STRAWSON INCLINOMETER
WARNING
IF THE INCLINOMETER EXCESSIVE TILT WARNING LIGHT ILLUMINATES AND THE
AUDIBLE WARNING SOUNDS, LOADING/UNLOADING OPERATIONS MUST CEASE
IMMEDIATELY.
86
The Strawson Inclinometer consists of two units, the sensing head housed in a gimbal assembly
mounted on the rear chassis frame crossmember, and the alarm unit (See Fig 1 (8)) located in the cab
header shelf above the drivers head.
87 · The alarm unit will give .an audible and visual.warning when the sensing head detects a side tilt
angle in excess of 5 degrees either side of centre in the lateral plane, or, 18 degrees tilt angle in the fore
and aft planes.
88
The gimbal assembly allows the sensing head to be rotated in excess of 5 degrees either side of
centre in the lateral plane and 18 degrees in the fore and aft planes to enable a non-operational test of
the inclinometer function.
Alarm unit test facility
89
Energise the vehicle electrical system by turning the master start key to position "2". Turn the LHS
mode rotary selector switch to position "1" (auto) (See Fig 9), this will illuminate the PTO red warning
light, the inclinometer alarm unit green 'wine glass' symbol and activate the audible warning momentarily.
90
Pressing the test button below the green 'wine glass' symbol will illuminate the red 'tilted wine
glass' symbol and activate the audible alarm.

91
NOTE: Only when the conditions described in Para 90 have been met, should the following tests
be carried out.
92
Lateral inclination test- RH
92.1 To test the RH 5 degrees setting, slacken the two screws (5 & 6) securing gimbal bracket
(3) to pivot bracket (2).
92.2 Rotate the sensing head (1) and gimbal bracket (3) clockwise (when viewed from the front)
until it reaches the stop.
92.3 When the stop has been reached, the red wine glass on the alarm unit should illuminate, the
audible alarm should sound and the green wine glass should be extinguished.
93
Lateral inclination test - LH
93.1 To test the LH 5 degrees setting, rotate the sensing head and gimbal bracket anti-clockwise
past the alignment mark on pivot bracket until it reaches the stop on the LH side.
93.2 Again the red wine glass should illuminate, the audible alarm should sound and the green

10 Unlock and release the start pilot plunger (Chap 2, Fig 1 (45)) and fully depress the accelerator pedal.
.Operate the starter motor and simultaneously pump the start pilot plunger to deliver two full strokes of
fluid.
NOTE
If after 30 seconds the engine fails to start, allow two minutes before attempting to restart the
engine.
11 When the engine fires and runs, operate the start pilot as necessary to assist the engine until it is
capable of running unaided up to a maximum engine speed of approximately 1,000rpm. When the engine
is running satisfactorily turn and lock the start pilot plunger in position before driving off.
TO STOP ENGINE:
12 Allow the engine to ru·n at idle speed (550-600rpm) in neutral for at least three minutes before
stopping .the engine by means of the master start switch (Chap 2, Fig 1 (48)). This will allow the turbo
charger to reduce speed and temperature.
13 In an emergency, push the engine stop button in the front of the vehicle.
TO DRIVE OFF
14 Fasten seat belts.
15 Check the brake air pressure and ensure that all reservoirs are at full pressure. DO NOT attempt to
drive the vehicle if the warning buzzer is sounding or the low air pressure warning lights are illuminated.
The spring brakes cannot be fully released below (8 lb/sq in).
16 Ensure that there is sufficient oil pressure in the engine, 207kN/sq.m (30 lb/sq.in) at idling speed.
350-480 kN/sq.m (50-70 lb/sq.in) at normal running.
17 Check that the differential locks and front wheel drive are disengaged if the vehicle is to be driven
over normal road surfaces.
TRANSMISSION
CAUTION • Transmission
Do not select reverse gear when the vehicle is moving forward or select a forward gear
whilst the vehicle is moving backwards. The vehicle must be stationary and the engine at
idling before making these gear selections.
18 The engine should be at idle and the vehicle stationary when any shift from neutral to a drive range is
made. If a drive range is selected with engine speed above 900rpm and/or with the accelerator
depressed, an interlock in the automatic control unit prevents a gear being selected.
19 With the engine at idling, select the desired speed range on the gearbox selector lever, release the
parking brake and depress the accelerator.
20 Depressing the accelerator influences the automatic shifting. When the pedal is depressed as far as
the contact point for the kickdown switch the transmission will automatically upshift to near the governed
speed of the engine. A partially depressed position of the pedal will cause the upshifts to occur sooner, at
a lesser engine speed.

21 Depressing the accelerator to the kickdown position will effect the earliest possible change to a lower
.gear.
22 A lock up clutch in the torque converter provides a direct mechanical link between the engine and
planetary gearbox.
23. Speed ranges are selected by moving the gear selector lever (Fig 2(1 )) to the following positions:
?3.1
R- Reverse
23.2
N- Neutral

24 The hydraulic retarder is operated by button (3) mounted on the rear face of the gear selector lever
console. It is designed to supplement the vehicle's main brakes not to replace them. Selection of the
retarder is recommended during descent of long shallow gradients which would otherwise require
constant light braking, or used with the vehicle brakes to give maximum braking effect in the event of an
emergency.
25 Full retarder operation without interruption is available in all forward gears.

26 When the retarder is selected with the accelerator in the idling position, an upshift lock comes into
effect. If the accelerator is depressed with the retarder selected, the retarder will automatically disengage
and the upshift interlock will be removed, when the accelerator is released the retarder and interlock will
come back into operation.
27 The transmission oil temperature must n.ot be allowed to exceed 150 degrees C C300 degrees F).
28 If excessive transmission oil temperature is indicated when the retarder is in operation, the vehicle ·
must be slowed down using the vehicle brakes until a downshift is made into a lower gear in which the oil
temperature does not exceed the given limits.
29 Should the oil temperature remain in the danger zone the retarder must be switched off completely. If
this does 11_()t c:aus~ th~E! oil temperatyre to drop, the vehicle must be brought to allalt Put the gearbox in
NEUTRAL and depress the accelerator fully. Within a few seconds a visible decrease in oil temperature
should result. Should the high temperature persist, stop the engine and have the ove'rheating condition
investigated by qualified personnel.
EMERGENCY GEAR LEVER
CAUTION
Ensure that the parking brake is applied and the engine is at idle before operating the
emergency gear lever. Failure to apply the parking brake will allow the vehicle to move
immediately the gear is selected.
30 The emergency gear lever (Chap 2, Fig 1 (59)) permits travel in 3rd and reverse gear only in the
event of failure of the vehicle electrical system or transmission electronic control unit.
GEARBOX DRIVEN STEERING PUMP
31 The gearbox driven steering pump maintains the supply of hydraulic pressure to the power steering
system, in the event of engine shutdown and vehicle coasting, when the vehicle is being towed, or, failure
of the engine driven steering pump under normal vehicle operating conditions.
TOWING
32 The automatic transmission is fitted with a secondary oil pump, this allows the vehicle to be towed
forwards without restriction to distance but speeds must be reduced accordingly. To tow the vehicle
rearwards the gearbox to transposing box propshaft must be disconnected.

Emergency release
48 In the case of total loss of air pressure in the braking circuits the spring brakes will be automatically
applied.
49 Operation of the emergency brake release (Chap 2 Fig 1 (56)) allows air pressure from an
independent reservoir to be supplied to each spring brake actuator to release the brakes. At the same
time a warning bell will ring. The reservoir holds enough air pressure for one application of the emergency
brake release system.
Manual release
WARNING - SPRING PRESSURE
THE SPRING BRAKE ACTUATORS CONTAIN AN EXTREMELY POWERFUL COIL SPRING.
THERE IS A RISK OF SERIOUS PERSONAL INJURY IF INEXPERIENCED PERSONNEL
ATTEMPT TO RELEASE THE ACTUATORS PARTICULARLY IF THE ACTUATORS HAVE
SUSTAINED ACCIDENT DAMAGE.
50 The spring brake actuators can be released mechanically as follows:
50.1
Scotch the tractor wheels.
50.2 Remove the breather cap from the end of the spring brake cylinder and unscrew the release
bolt until the brake shoes are free from the drum.
NOTE
REME assistance is to be requested to carry out this operation.
MANOEUVRING BRAKE
51 The manoeuvring brake is fitted to control the vehicle movement during load handling system
operations.
52 The manoeuvring brake valve (Chap 2 Fig 1 (44)) is foot operated by the driver, and will only operate
with the transmission selected in '1' (first) or 'R' (reverse).
53 During this operation air is supplied only to the bogie brakes.
POWER STEERING WARNING LIGHT
54 The power steering warming lamp (Chap 2 Fig 1 (1 )) will illuminate should one of the hydraulic pumps
supply pressure fail. Hydraulic pressure will be maintained for the steering system from the serviceable
pump via the automatic change over valve.
NOTE
The warning lamp will illuminate when the vehicle is brought to a halt with the engine running.
55 Should both hydraulic pumps fail the vehicle remains steerable but a considerably higher effort has to
be applied to the steering. As such a situation occurs very seldom and then in most cases totally
unexpectedly, the driver may erroneously come to assume that the steering system is locked up.
However, this is not the case. The driver must apply the necessary increased steering effort to perform
the steering manoeuvre.

Unloading on to higher ground (loading dock)
109To drop a flatrack onto a loading dock or a similar situation, it is important that the height is
determined by reversing up to the dock with the projection of the flatrack over the dock, check that there
is a minimum of 150mm (6 in) between the bottom of the rear corner casting of the flatrack and the dock.
11 0 Should there be enough clearance, fit the rollers to the flatrack, unload as normal releasing the
hand brake when the flatrack touches the dock and then pushing into place when it is off the vehicle.
Unloading on to lower ground
111 No special techniques are required to unload a flatrack below ground level, other than to make sure
there is enough travel in the hook arm to unload. Also take care that the flatrack does not hit the rear of
the vehicle.
EXTREME ANGLE BETWEEN FLATRACK AND LHS
112 Should it be impossible to approach the flatrack at a reasonable angle, the following procedure
should be adhered to:
113 Hook onto the flatrack and check that the hook bar is sitting down in the hook correctly, failure to do
this could twist the hook, should the bar not sit in the hook correctly, pull the flatrack out with chains
between the hook and the flatrack.
1141f the bar sits correctly in the hook, follow the normal loading procedure, steering the vehicle
underneath the flatrack but taking care during fitting that the rear lights do not hit the front of the flatrack ask someone to check the clearance as the flatrack is pulled on.
·
115 Because of limited steering lock, difficulty may be experienced in steering under the flatrack far
enough, and if this is so, pull the flatrack on as far as possible, then apply the opposite lock and push off
again, then reversing the .lock again pull on the flatrack which should come on to the rollers. If not,
continue the process until it does.

BLACK OUT OPERATIONS
116 When operating in blackout conditions, ensure there are personnel each side at the rear, and in
contact with the operator, to check that the flatrack locates on the rear rollers correctly.
RESTRICTED HEIGHT OPERATION
117 Should there be insufficient headroom to load or unload a flatrack, rear rollers should be attached to
the flatrack and it should be unloaded and then pushed to the desired drop area. When pulling or pushing
the flatrack the front should be lifted approximately 300mm (12 in) before moving.
118 Should the normal loading or unloading operation be unable to handle the flatrack for any particular
reason, by using 'manual' mode it is possible to move the hook frame to alter the geometry and lift the
flatrack that way, but the hook frame must be returned to its normal loading position before the flatrack is
fully pulled on.
OPERATING ON AN INCLINE
119When operating on a hill have the vehicle facing downhill, this will allow normal operations. Use of the
manoeuvring brake when in first or reverse, or the footbrake will be necessary if the vehicle is facing up
hill, or, the vehicle and flatrack are likely to move downhill.
SLAVE HYDRAULIC COUPLINGS
WARNINGS
(1) ALL SLAVE HYDRAULIC COUPLING CONNECTIONS AND DISCONNECTIONS MUST BE
MADE WITH THE VEHICLE ENGINE SWITCHED OFF. WHEN COUPLING THE PRESSURE
MUST BE RELIEVED IN THE LHS FEED CIRCUIT.
(2) HIGH HYDRAULIC OIL PRESSURE IS PRESENT IN THE FLEXIBLE HOSES WHEN
CONNECTED TO THE SLAVE COUPLINGS. PERSONNEL SHOULD STAND WELL CLEAR
WHEN THESE HOSES ARE IN USE IN CASE OF SEPARATION OR BREAKAGE.
(3) SAFETY MUST BE PARAMOUNT WITH ALL ROUND VISIBILITY BEING MAINTAINED AT
ALL TIMES, ESPECIALLY WHEN THE VEHICLES ARE MOVING IN REVERSE.
(4) ENSURE THAT THE HYDRAULIC PIPES ARE NOT ALLOWED TO DRAG ON THE FLOOR
WHEN THE VEHICLES MOVE.
120The two quick release couplings (Fig 9 (1 )) located on top of the LHS reservoir are used for supplying
hydraulic power to a stricken LHS on another vehicle.
121 When using the slave hydraulic couplings the mode selector switch must be in the 'AUXILIARY'
position on the 'live' vehicle. On completion, the slave coupling and the mode selector must be returned
to the 'OFF' position.
122 Ensure before connecting the couplif1gs that the pressure in the LHS feed circuit is relieved. To
relieve the pressure, disengage the PTO and switch the engine 'OFF', switch electrical power 'ON' and
select 'AUTO' on the LHS mode selector, connect the hydraulic hoses to the slave couplings, select LHS
to 'OFF', start the engine and select LHS mode to 'AUX'.
OFF LbADING A 'DEAD' DROPS VEHICLE LHS USING HYDRAULIC SLAVE CO.UPLINGS
123 The procedure details the operations required to off-load a flatrack from an unserviceable 'dead'
vehicle, using the assistance of a serviceable 'live' vehicle. The procedure is applicable to both MMLC
and IMMLC DROPS
124 The task may be performed by either a two or three person team. When using two people, a 'live'
vehicle with a loaded flatrack must first be offloaded to ensure unrestricted visibility between the
operators. Only when a third person (Banksman) relays the signals between the operators can the 'live'
vehicle remain in the loaded condition.

neutral position.
168 Also in the hatch observer platform is the emergency spring brake release lever (See chap 2
Fig 1 (57)). In the case of the total loss of air pressure in the casualty braking circuits, operation of this
lever will allow air from an independent reservoir to release the spring brakes for one application only.
NOTE
A warning bell will sound with the casualty electrics switched on when emergency spring brake
release is selected
169 A secondary oil pump incorporated in the gearbox allows, forward towing without disconnection of
propshaft.
170
The casualty may be towed without restriction to distance but speeds must be reduced accordingly.
171 Should the casualty engine be inoperative, a gearbox driven emergency steering pump will provide
hydraulic power to the steering system while the casualty is moving in either direction.
172 In the case of failure of either the gearbox, steerdrive axle, or rear bogie axles the stricken
component should be isolated by removing the appropriate propshafts.
Front and rear towing points
173. The front bumper incorporates a towing pin and jaw, the rear chassis cross member a towing
pintle. Recovery eyes to DEF STAN 25-6/3 are fitted to the front and rear of the vehicle. Recovery eyes
can only be used for suspend tows.

GEARBOX
45
The six speed automatic gearbox consists of a torque converter with lock up clutch, retarder and a
planetary geartrain.
CAUTION
GEARBOX SAFETY. The maintenance of the correct oil level is of great Importance for an
automatic gearbox. Low oil level will result in gearbox defects and malfunction. Too high an
oil level results in the transmission overheating. Oil level checks must be carried out at
regular intervals (weekly). Vehicle must be on a level standing. Gearbox must be in neutral
position with the engine running at Idle, speed. The transmission and oil must be hot for
accurate oil level checks. The purpose of the cold level inarks are only to determine if it is
safe to- run the vehicle until an oil level check can be-mad-e atnorma!"operatlng temperature.~ . ~ ..
To check gearbox oil level (See Fig 12)
46
The gearbox dipstick (Fig 12(1)) is housed in the oil filler spout located on the right hand side of the
gearbox housing.
46.1 The dipstick is marked with an upper, high level, STOP mark and two zones or operating
ranges. The upper zone indicates the level range at operating temperature (HOT) and the lower
zone, the cold oil level. The bottom mark of the cold zone also indicates the minimum oil level.

CAUTION
GEARBOX SAFETY. When a vehicle has been parked and stationary for several hours the
main gearbox oil: level should be higher than. the 'hot zone' marks on the dipstick but
below the STOP mark. If this is not the case; oil must be added before starting the engine.
Jun 13
Chap4
Page 15
2320-R-301-201
ARMY EQUIPMENT
SUPPORT PUBLICATION
47
When the vehicle has been stationary for a period of time the transmission oil drains out of the
convertor. As a result, a high reading between the top hot zone mark and the STOP mark is indicated on
the dipstick.
47.1 Do not drain any oil because of this result. A high oil level is normal for a cold transmission
before the engine is started. See CAUTION.
Cold"oillevel check
48
To make a cold oil level check of the main gearbox, start the engine. After approximately two or
three minutes of running at idle speed check the main gearbox oil level; the correct oil level is within the
'cold zone'. The colder the oil temperature, the. lower the oil level.
48.1 If the oil level is below the 'minimum level' mark, then oil must be added immediately. Only
when the oil is within the 'cold zone' mark should the engine be warmed up or the vehicle driven.
48.2 Due to the churning effect of cold oil, an "excessive" oil level may be found. However, do not
drain any oil because of the result of the cold oil level check. The transmission and oil must be hot
in order to achieve an accurate oil level check. The purpose of the 'cold level' marks are only to
determine if it is safe to run the vehicle until an oil level check can be made at a normal operating
temperature.
48.3
Finally, make a further oil level check at operating temperature and adjust level accordingly.
Operating temperature (hot) oil level check
49
To carry out an operating temperature (hot) oil level check on the main gearbox, run the engine at
idle speed until the oil temperature reaches between 80° - 90°C ( 175° -195°F). The correct oil level is
between the high and the low marks of the 'hot zone'.
49.1 If the initial check shows that the oil level is not in the 'hot zone', repeat the level check
again and ensure that the dipstick cap seats firmly into the bayonet fitting when the dipstick is
inserted. In addition, check that the oil and transmission are at the correct temperature.
To add oil to the gearbox.
50
Oil is added to the main gearbox through the filler spout (See Fig 12) which also houses the
dipstick. Do not allow the level to go above the STOP mark.
To drain the gearbox oil
51
If possible, operate the gearbox until normal operating temperature (80° to 90°C, 175° to 195°F) is
reached prior to draining the oil.
51.1 Place a suitable container beneath the sump drain plug (Fig 13(3)) ready to receive the
drained oil. Main gearbox oil capacity is approximately 251itres (5 1/2 galls).
51.2
Remove the drain plug (3) from the base plate of the gearbox and wipe clean.
51.3 Renew the drain plug seal, fit plug and tighten to 50Nm (37ft lbf). DO NOT overtighten drain
plug.
51.4
Proceed to change the gearbox oil filter before filling the gearbox with new oil.

111 The tyres should be inspected regularly for damage and depths of tread. If a tyre is damaged or the
depths of tread is below the legal minimum THE TYRE MUST BE REPLACED.
To inflate a tyre (See Fig 29)
112 A dual tyre inflator controlled by a two way cock, situated in the LH side stowage box, is provided
to make tyre inflation possible from the vehicle air system. The inflator is equipped with two self sealing
quick release adaptors to allow the inflation of one or two tyres simultaneously. The method of inflation is
as follows:
113 Start the engine and set to run using the hand throttle. Op~rate the brakes to exhaust some air
from the system. This will ensure that the governor is not unloading. Connect the tyre inflation hose(s)
firstly to the inflator by pushing upwards the knurled sleeve on the quick release_adaptor(s) (2)~ncl firmly_
inserting-the hose quick release -coupling(s}into fhe adaptor(s). Release the sleeve to lock the coupling
then attach the other end of the hose(s) to the tyre(s).
114
Turn the handle on the inflation cock (1) to the 'INLINE' position to admit air to the tyre(s).
115
On completion of tyre inflation turn the handle to the 'OFF' position.
116 When disconnecting the inflation hose, always remove it first from the tyre then from the inflator
connection, otherwise a loss of air will result. To disconnect from the inflator reverse the connection
procedure.
To deflate a tyre (off-road conditions) (See Fig 29A)
WARNING
WHEN DEFLATING TYRES TAKE CARE TO KEEP THE BODY, PARTICULARLY BARE SKIN
AND EYES, CLEAR OF THE AIR STREAM; SAFETY GOGGLES MUST BE WORN.
117 A set of four deflation valves in a black leather wallet are provided for this purpose. There are two
valves with knurled head plungers for the front tyres and two with hexagon head plungers for the rear
tyres. The deflation method is as follows:
118 Select the appropriate valve, front or rear, and decide which of the valve settings relates to the type
of terrain on which the vehicle will be operating.
119 Set the valve by holding the knurled fixed ring between the thumb and forefinger of one hand and
the operating plunger between the thumb and the forefinger of the other hand. Push the plunger down
and turn it clockwise for sand terrain and anti-clockwise. for gravel track terrain.· Release the plunger to
engage the selected slot.
120 Remove the tyre valve adaptor cap and store safely. Using a small clean screwdriver or similar
implement, momentarily depress the. valve core and allow a discharge of air to dispel any dust or grit
particles which may be present.
121 Making sure that the valve adaptor thread is clean, screw 'the deflation valve onto the adaptor.
Resistance will be felt when the sealing washer in the valve contacts the adaptor. Continue to tighten
using light finger pressure only until a loud noise of escaping air is evident. Do not overtighten.
122 When the sound of escaping air has reduced to a gentle hiss, press and release the plunge'r.
Unscrew the deflation valve and replace the valve adaptor cap using reasonable finger and thumb force.
123
Repeat Paras 117 to 122 for the other tyres.

GENERAL DESCRIPTION
The EKA Simple Rail Transfer Equipment is specially designed for the unloading and loading of
flatrack loads at rail head areas.
WARNINGS
(1)
ENSURE THAT PERSONNEL ARE CLEAR OF THE VEHICLE AND LIFTING AREA.
(2) ENSURE THERE ARE NO OVERHEAD POWER CABLES OR OBSTRUCTIONS THAT
MAY COME INTO CONTACT WITH THE B.OOMS THROUGHOUT THEIR RANGE OF
MOVEMENT.
(3) ALL SLAVE HYDRAULIC COUPLING CONNECTIONS AND DISCONNECTIONS MUST BE
MADE WITH THE VEHICLE ENGINE SWITCHED OFF. WHEN COUPLING THE PRESSURE
MUST BE RELIEVED IN LHS FEED CIRCUIT.
(4) ENSURE PALLET LOAD LASHINGS AND SIMMO ARE IN GOOD CONDITION AND LOAD
SECURE TO PREVENT SLIP.
(5) VALVE CHEST AND PIPELINES POSITIONED BELOW LEVEL OF SRTE CHASSIS ARE
VULNERABLE EQUIPMENT. THE SRTE MUST ONLY BE DISMOUNTED FROM BEARER
VEHICLE ON TO A SMOOTH FLAT SURFACE.
CAUTIONS
(1) Check the around conditions for firmness and inclination. Any around instability
beneath the stabiliser feet or vehicle wheels could affect the safe operation of the Simple
Rail Transfer Equipment.
(2)
The S.R.T.E. chassis overhangs the rear of the vehicle by approximately 1850 mm.
(3) Ensure that the hydraulic hoses do not get trapped between the rear rocking arm and
stabiliser extension housing when retracting stabiliser.
(4) The S.R.T.E chassis when mounted increases the vehicle overall width by
approximately 175 mm either side. Care should be exercised when passing vehicles,
buildings or similar obstructions.
(5) All self sealing hose couplings, connectors and stowage dummy couplings must be
maintained in a clean and serviceable condition. Weatherproof blanking caps must be fitted
when this equipment is not in use.
2
Ensure before connecting the couplings that the pressure in the LHS feed circuit is relieved. To
relieve the pressure, disengage. the PTO and switch the engine 'OFF', switch electrical power 'ON' and
select 'AUTO' on the LHS mode selector, connect the hydraulic hoses to the slave couplings, select LHS
to 'OFF', start the engine and select LHS mode to 'AUX'.
CONTROLS AND INSTRUMENTS

extension.
37
Deploy fully out the rocking arms.
38
Retract rocking arm extensions to enable shoes to be fitted to flatrack, lock handles when
connected.
39
Lift up flatrack by first tensioning the lifting chains by extending and retracting rocking arms. When
chains are equally tight, retract rocking arms, extend rocking arms as necessary to prevent flatrack
fouling MM chassis. Load onto locating pegs on SRTE frame. When load correctly located, stow arms
fully, lift stabiliser jacks and retract stabiliser extensions.
40
Disengage PTO and move MMLC, SRTE and load to unloading point,
41

USE OF THE EXTENSION FEET AND LOAD; SPREADERS'
Extension feet
52
If the stabiliser jacks are fully extended but do not reach the ground, or if it is not possible to level
the SRTE by extending the jacks, the extension feet must be fitted.
53
These are intended for use when the surface onto which the stabilisers must bear is up to 300.mm
below the road surface on which the vehicle is standing.
54
Whilst the extension feet may be left attached to the stabilisers during transfer operations in a rail
yard, they must be removed and stowed prior to road travel, as the SRTE is over legal width when the
stabilisers are retracted with the extension feet fitted.

It is essential for the safe operation of the SRTE that the stabiliser jacks are only allowed to bear
on a surface which will not sink or collapse under load during the transfer operation.
56
When transferring a flatrack from a rail wagon the stabilisers will normally bear on the wc;~gon deck
and it is essential that one of the wagon main sidemembers is directly beneath each of the stabiliser feet.
If the planking over the chosen sidemember is damaged or uneven, a load spreader must be ·placed
beneath each of the stabiliser jacks.
57
Similarly, when the SRTE is transferring the load to the ground the stabilisers should normally bear
onto a flat concrete surface. However, if the ground is uneven, or of a compacted soil or if there is any
ris_k oftl1e surface 'giving way' u.nder loa_d, the load spreaders must also be used.
58
The load spreaders must be such that with the maximum stabiliser jack load applied they should
not unduly distort or crack. A typical spreader would be about 600 mm square made of cross-bolted
hardwood 100 mm thick, or sheet of 20 mm thick steel plate.
HYDRAULIC RESERVOIR

(14) REPEATED FAILURE OF THE SAME FUSE INDICATES A CIRCUIT FAULT WHICH
MUST BE INVESTIGATED AND RECTIFIED.
CAUTIONS
(1) The blink code system is intended as a Workshop diagnostic aid and must only be
operated by authorised workshop personnel. Comprehensive operating instructions are
contained in AESP 2320-R-301-512, Annex A, Chap 10.
(2) The ABS diagnostic socket must only be used in conjunction with the WABCO
Diagnostic Controller. The use of any other electronic test equipment may cause irreparable
damage to the ABS electronic control unit (ECU).
(3) The multimeter is an integral component of the diagnostic controller and has been
designed for the measur~ment of the vehicle specific range (low voltage). It must not be
used beyond its quoted measuring range.
(4) Damaged sustained to the ABS trailer socket or protective hinged cover will
necessitate the renewal of the complete socket assembly and the entire ABS trailer wiring
harness.
(5)
Do NOT use the ABS exciter ring as a lever (fulcrum) point.
(6)
Do NOT strike or dent the ABS exciter ring; protect the ring from damage.
(7)
Do NOT support the hub on the ABS exciter ring.
(8) To prevent damage to the ABS sensor when fitting the hub, push the sensor into the
mounting bracket until flush with the bottom face of the sensor bore.
(9) The ABS exciter rings-are non-serviceable components. In the event of accidental
damage to any exciter ring, the affected hub assembly must be renewed.

AXLES
1
Each hub on the front steer driven axle and each hub on both rear axles is fitted with an anti-lock
braking system (ABS) exciter ring .
.2
The brake brackets on the front steer driven axle and both rear axles are fitted with ABS sensor
mounting brackets. Each sensor is held in position by a special spring clamp bush.
BRAKE SYSTEM
Foundation brake assemblies
3
In accordance with current EEC legislation, the brake shoe linings are manufactured from a nonasbestos friction material.
4
The brake shoes used on all ABS equipped vehicles, have a 12 mm access hole machined in each
brake shoe to enable the ABS wheel sensor to be adjusted.
5
The brake drum assemblies on the drive steer front axle are fitted with a 2-piece brake drum dust
cover assembly. Removal of the upper dust cover will expose the brake shoe ABS sensor access hole.
Pneumatic brake system
6
Additional relay valves are fitted to the front and rear brake circuits to enable the vehicle braking
system to achieve rapid brake respon~e times in accordance with current EEC directives.
7
The vehicle air system is equipped with a revised multi-circuit protection valve that incorporates a
full feedback function. The full feedback function is an inherent safety feature that ensures that there is
sufficient service brake pressure before the handbrake (park) brake can be released.
8
The second steer axle is equipped with type 24 service brake chambers. The revised brake
chambers are used to enhance the braking performance and achieve a balance brake response.
Anti-lock braking system (ABS)
9
All vehicles are, equipped with a WASCO 'D' type (six-channel) anti-lock braking system (ABS).
10
The primary function of the ABS is to prevent the wheels of the vehicle locking due to brake
applications whilst travelling on low adhesion road surfaces (e.g. ice, water, loose gravel etc.). The ABS
is a fully automatic system and does not require any action on part of the driver to operate or select the
ABS operation.
11
The operational-integrity of the vehicle ABS and, when applicable, trailer anti-lock braking systems
are monitored byABS warning lamps which are mounted in the instrument panel (see Para 15).
12
An ABS trailer socket is fitted adjacent to the standard towing couplings on the rear towing crossmember. The ABS trailer socket-conforms to the requirements of ISO 7638.
13
The ABS incorporates a rudimentary fault diagnostic system. This system utilises the 'ABS'
warning lamp to transmit a coded message ('blink code') indicating the operational integrity of the vehicle
ABS components.
CAUTION
The blink code system is intended as a Workshop diagnostic aid and must only be operated
by authorised workshop personnel: Comprehensive operating instructions are contained in
AESP 2320-R-301-512, Annex A, <;:hap 10.

ABS ELECTRICAL SYSTEM
14
The vehicle ABS electrical circuits are protected by three plug-in blade type fuses which are
attached to the main electrical component board beneath the centre fascia
15
The instrument panel incorporates two additional warning lamps that monitor the operational
integrity of the anti-lock braking system (ABS). The 'ABS' warning lamp monitors the vehicle ABS whiist
the 'ABS TRLR' monitors the trailer ABS.
NOTE
The 'ABS TRLR' warning lamp will only function whilst the vehicle is connected to an ABS
equipp~d trail~r.
16
The vehicle electrical system incorporates five. additional electrical wiring harnesses for the antilock lock braking system (ABS).

The ABS electrical circuits incorporate a gearbox retarder inhibit circuit. This electrical inhibit circuit
will automatically disable/disengage the gearbox retarder whenever an ABS wheel slip condition is
detected: Normal operation/re-engageinent of the gearbox retarder will be automatically resumed when
. normal tyre adhesion is established.
FV lighting switch circuit
7
The ABS electrical circuits incorporate an FV lighting switch inhibit circuit. This electrical inhibit
circuit will automatically disable the ''ABS." and ''ABS TRLR" warning lamps whenever the FV lighting
switch is in the "C" (convoy) or "CS" (convoy/sidelight) lighting positions.

ABS DRIVING INSTRUCTIONS
WARNINGS
(3) DO NOT ABUSE THE ANTI-LOCK BRAKING SYSTEM BY BRAKING HARSHLY OR BY A
DELAYED APPLICATION OF THE SERVICE BRAKES.
· (4) DO NOT RELY UPON THE ABS TO SHORTEN THE OVERALL STOPPING DISTANCE OF
THE VEHICLE. DEPENDENT UPON THE ROAD CONDITIONS, THE OVERALL VEHICLE
STOPPING DISTANCE CAN BE INCREASED.
(5) TO MAXIMISE THE EFFICIENCY OF THE ABS SYSTEM, DO NOT USE A CADENCE
BRAKING TECHNIQUE (i.e. RAPID AND. REPETITIVE APPLICATIONS OF THE SERVICE
BRAKES). WHEN BRAKING, ENSURE THAT A CONTINUOUS PRESSURE IS APPLIED TO
THE FOOTBRAKE PEDAL.
(6) FAILURE OF THE VEHICLE OR TRAILER ABS WARNING LAMPS TO ILLUMINATE
INDICATES A POSSIBLE MAJOR MALFUNCTION OF THE ABS ELECTRONIC CONTROL
UNIT (ECU).
(7) IN THE EVENT OF A VEHICLE COMBINATION ABS FAILURE THE DRIVER MUST
COMPENSATE HIS DRIVING TECHNIQUES ACCORDINGLY.
1
The anti-lock braking system (ABS) prevents the vehicle road wheels from locking during an
emergency stop or when braking on a slippery road surface. The ABS will enable the driver to retain full
control of the vehicle and maintain directional stability during an ABS detected wheel lock condition.
2
It is essential that the vehicle be driven in a safe and conventional manner. Do not adapt your
normal driving style when driving a vehicle equipped with ABS.
3
If during the 'first parade service' an ABS warning light remains illuminated the fault must be
reported; do not proceed until authorised.
NOTE
When towing a DROPS trailer fitted with ABS, the trailer warning lamp will remain illuminated and
will extinguish when the vehicle combination road speed exceeds 6 km/h. If the warning lamp does
not extinguish, carry out the same action as with a vehicle fault.
4
If during the journey an ABS warning light illuminates this indicates, an ABS. fault has occurred
which, will return- the vehicle to a conventional braking system. Missions can be completed as the
conventional braking system remains fully operational. On completion of the mission the fault must be
reported.
