REMOVE ALL GAGES - Reset the PowerView's gage memory.
SOFTWARE VERSION - View the PowerView's software version.
FAULT CODE CONVERSION - View/edit the J1939 fault code conversion method.
NOTE: There are four (4) different methods for converting fault codes. The PowerView always
looks for J1939 Version 4 and can be set to read the code as one of three (3) other J1939
versions if Version 4 is not being used. Most engine ECU’s use Version 4, therefore in most
cases adjustment of this menu option will not be required.
Upon receiving an unrecognizable fault, change to a different J1939 Version. If the fault SPN
does not change when the version is changed, the ECU generating the fault is using Fault
Conversion method 4. If the SPN number does change but is still unrecognizable, try changing to
another J1939 Version not yet used and continue to check the SPN number.
5. ANALOG INPUT – provides two setting options:
BACKLIGHT DIMMER, the default setting, will accept an optional backlighting dimmer.

IMPORTANT
The radiators must be kept clean and free of
obstruction AT ALL TIMES.
To clean the engine radiator –
Release the bottom hydraulic hose (from oil cooler) from
clamp under chassis (next to hydraulic reservoir).
Releasing the wing screws on the front of the radiator allow
the hydraulic radiator to PULL FORWARD so that the main
engine radiator may be cleaned. Release the bottom
hydraulic hose from its clamp on the chassis to fully move
the radiator.

Engine Air Intake Cleaner
The air cleaner is fitted with a vacuum gauge linked to a warning
light in the main console. When blocked the air cleaner element
will need cleaning or replacement.
SPECIFICATION
The air cleaner consists of a pre-cleaner assembly, which
generates a cyclone effect with the incoming air, throwing the
larger dust particles to the outside. The particles are then
sucked into the exhaust and ejected. It is important to ensure
the pipe between the pre-cleaner and exhaust is in place and
undamaged.
The air is then drawn into the main air cleaner containing two
paper elements, inner and outer. The inner element acts as a
safety element should the outer element becoming damaged.
The vacuum sensor will illuminate the instrument warning light
when the element has become blocked and is restricting air flow
to the engine.
The air compressor also takes its inlet air from the air cleaner.
MAINTENANCE
Remove the elements by unclipping the end housing and holding
firmly; draw back the outer element; it is held by a rubber
grommet on the inside that forms an air seal.
Always replace both elements together and ensure the rubber
seal is in good condition, they are correctly fitted and the end
cap re-fitted. Check also the hose and pipe from the air cleaner
to the engine is in good order and the band clamps are tight.
Any gap can lead to air being drawn directly into the engine
causing wear and failure.
IMPORTANT
If any of the air cleaner pipework to the engine is damaged,
the vacuum gauge is lost or sealing bands are broken,
replace these immediately before continuing to use the
machine.
The following four pages have specific information on the
servicing procedures for the air cleaner filter elements.

Pump/Motor Signal Valve
The control signal used to operate the motor from the pump is
isolated to the motor in LOW range to limit the speed to 4.2 kph.
Otherwise the ground speed in low range would be 7.2 kph
maximum.
The signal valve is positioned on the inboard side of the RHS
conveyor immediately above the drive motor & below the pressure
filter.
To override this valve and allow the motor to change
displacement in LOW speed, set the valve manual override into
the MANUAL POSITION.

If the valve fails to operate correctly, the High speed range will
also not achieve full speed of 28 kph but will be limited to 16
kph.
Maintenance
The hydrostatic circuit uses all Sauer-Danfoss components, as is
the control circuit and joystick, which do not require any regular
maintenance.
In the event of system performance failure, either contact
Phoenix Engineering or your local Sauer-Danfoss dealer for
assistance.

Pump priming –
In the event of a major hose failure or hydraulic oil leak,
the hydrostatic pumps will need priming with oil BEFORE
starting. This will prevent internal failure through poor
lubrication.
When priming the circuit it is recommended that the engine
be turned over, but prevented from starting, until hydraulic
oil has completely entered all of the circuit.
If dismantling the hydrostatic circuit, it is recommended that
specific information on the pump and motor servicing be
obtained first from Phoenix Engineering or Sauer Danfoss.
Cleanliness
At any time, when the circuit is dismantled, it is most
important to ensure dirt is not allowed to enter. All hose
unions or ports must be kept sealed and be cleaned before
being re-assembled.

2.2.3 Brake Circuit
Brake Specification
The brakes consist of
• Front & rear axle internal wet disc brakes, hydraulically
operated ON for service braking.
• Rear axle calliper hydraulically operated brakes, for
parking/emergency braking.
Brake sprung applied & pressure released to fail safe.
• Gearbox multi pack brake for parking/emergency use.
Brake sprung applied & pressure released to fail safe.
Hydraulic Brakes Circuit
Brake operation has three independent circuits that are all fitted
with accumulators to allow limited brake operation should the
power fail. Approximately 5 service and park brake operations
are possible before reserve hydraulic pressure is lost.
See circuit diagram SE703-01
Stored energy accumulators are used in the brake circuit. These
retain pressure when the power (engine) is off. This allows for up
to five brake operations until the reserve is exhausted.
IMPORTANT
If dismantling the hydraulic joints pressure in the lines will
need to be released. Operate all brake functions ten times
to drain the reserve pressure.
Maintenance
There is no regular service needed to the brake control
components. If these components fail to perform to specification,
they must be replaced IMMEDIATELY.
The hydraulic circuit used oil from the main hydraulic reservoir
and does not have its own supply.
The calliper brake pads need annual inspection.
See the ITL axle section for information on the maintenance of
the axle’s brakes.

Feedroller Circuit
Each of the three feedrollers is driven by its own high torque,
low speed hydraulic motor, as are the two extension agitators.
The centre section feedroller and agitator are driven through
chain and pinion. The motor is mounted onto a plate that can be
adjusted in increase drive chain tension. The extension
feedrollers and agitator drive directly into their shafts.
The flow from the hydraulic pump is feed into the main control
block. This block contains a main relief valve, a solenoid
proportioning flow control valve and a pair of solenoid valves for
each feedroller (R1,R2 &R3) The circuit feeds the centre
feedroller (R2) then left hand extension (R1) and last the right
hand extension feedroller (R3), all in series, to maintain equal
speeds on the feedrollers.
Each feedroller has its own control switch that acts upon that
pair of solenoid valves, so each feedroller is individually
controllable ON/OFF in any sequence. The master switch (on
Joystick) will trigger the proportional flow control to allow flow
into the remaining part of the circuit.
Phœnix ‘SPC10e’ Self Propelled Chipping Spreader
10/10
Instruction and Maintenance Manual
Sheet 2.53
The pair of solenoid valves consists of one normally open ‘NO’
and one normally closed ‘NC’. Both are de-energised when the
feedroller is stationary and energise to engage the feedroller
motor. The ‘NO’ solenoid normally allows the flow to divert past
that feedroller to the next and from there back to the hydraulic
reservoir. Each ‘NC’ solenoid shuts the circuit to the feedroller
so stopping the motor from rotating.
On the centre section feedroller there is a check valve mounted
directly next to the motor to counteract a small amount of
counter rotation when the circuit closes at the solenoids.
The solenoid valves will operate in the following sequence.
Master ‘OFF’
- All solenoid de-energised, all
feedrollers ‘OFF’
Master ‘ON’ & R2 ‘ON’- 1st pair solenoids energised,
centre feedroller only operates.
R1 and R3 ‘OFF’, 2nd and 3rd pair of solenoids deenergised.
Master ‘ON’ & R1, R2, R3, ‘ON’ - all solenoids
energised (6 no.) all feedrollers operate
The proportioning solenoid valve allows a proportion of the total
flow into the circuit that is a function of ground speed and the
setting of the FeedRoller Speed Adjuster. The bypassed flow is
passed into the tank line.
The optional extension hopper agitators have a manually
controlled hydraulic block mounted directly to their motors.
This hydraulic block contains a diverter valve.
HAZARD WARNING
The central position has a detent location in which
the lever must be set to disengage the agitator; failure
to correctly position the lever can restrict the flow
causing excessive load and heat to build up.

2.4 Spreading System & Aggregate Handling
2.4.1 Front Spreading Hopper
SPECIFICATION
Centre spread hopper with feedroller, feedgate, agitator, drive
system and 296mm wide individual shut-off-doors raised by
pneumatic cylinders.
Two extension hoppers with feedrollers, feedgates, optional
agitators and drive systems.
Extension rail support front and rear with hydraulic rams to
extend and retract hoppers.
MAINTENANCE
The feedrollers and feedgates must be kept in good order, to
ensure the performance of the spreading system is maintained.
Weekly, the threads on feedgate adjusters should be cleaned and
treated with a spray lubricant (such as WD40 or similar).
Check the feedgate mesh remains in good order and does not
wear away or locally lift off the feedroller surface. It must
remain tightly held onto the drum surface.
When the feedroller mesh requires replacement, (less than 2mm
thickness remains) the feedgate rubber, cut-off-door rubber and
feedroller scraper rubber should also be changed at the same
time.
To replace the feedroller mesh, dismantle from the hopper and
remove the old mesh from the roller with a hand chisel, breaking
the welds. Lightly grind the surface to clean off the old weld.
DO NOT grind off the mesh or use heavy grinding on the surface
of the feedroller as excessive heat can cause it to distort. Place
a pre-rolled mesh over the feedroller and clamp into place so
that it tightens down fully onto the surface. Weld short runs
along both ends and seam so that no loose edges are left.
When the length of the feedroller requires more than one section
of mesh, stagger the longitudinal join so that there is not a
continuous line of weld at one point for the full length.
Fixed on each end of each feedroller is a large diameter disc.
There are plates that closely fix over them (centre feedroller) or
on to their outside edge (extension hoppers) these should be
Phœnix ‘SPC10e’ Self Propelled Chipping Spreader

Instruction and Maintenance Manual
Sheet 2.63
adjusted or replaced as they wear, to prevent aggregate
becoming jammed behind the end of the feedroller and the
hopper outside plates.
IMPORTANT
Do not allow the feedroller to bow out of shape. A
distortion of even 1mm will lead to uneven spreading
characteristics.
When replacing the feedgate rubber, care must be taken to
ensure the bottom edge remains perfectly straight.
The feedroller scraper rubbers should be adjusted so that any
gap behind the feedrollers is closed up. However, they should
not be pushing onto the surface of the feedrollers.
The separate feedgates must all remain parallel to the feedroller
when replaced. Check by allowing feedgate rubbers to rest on
the feedroller so that along their full length they rest equally
onto the feedroller.
The agitator shaft has eccentric discs welded on to break up
lumps of aggregate. These discs will wear away when frequently
used and should be replaced. The remains of the old disc should
be ground away and new ones welded in their place.
The extension hopper support rails, front and back, is held on
nylon wear pads. These will only wear very slowly and, should in
normal use, last the life of the machine. If however the hopper
becomes slack on the rails additional packing can be placed
under the pads to take up this wear.
The scatter plates at the front of each hopper should be kept in
good condition and retain their straightness. If they become
damaged or bent, they should be immediately repaired or
replaced.
When the feedrollers or agitators are removed from the machine,
the bearings in which they rotate should be checked. Regular
greasing is not required, but they should be free running. The
bearings should be locked to the shaft to prevent movement
through the bearing occurring.
The extension hopper cut-off plates, located above the extension
feedroller and sliding over it, will catch aggregate. It should be
fully cleared and any aggregate fouling the slot in the extension
hopper removed. The level of wear on the end pushed though the

To adjust belt tension, slacken the nuts on the tail drum adjuster
screws and draw the tail drum down the slot, until sufficient tension
is applied. Re-secure the nuts on the tensioner.
Do not over tension the belts, as they will stretch if pulled too tight.
Only adjust the minimum amount if belt to drive drum traction is
lost and they slip on the drive drum.
Always ensure the tail drum remains square to the elevator belt
and parallel to the head drum. Always adjust by the same amount
on each of the screws.
Conveyor belt tracking :
If the belt, at the top or bottom, runs to one
side use the following procedure to centralise it.
1)
Ensure the head drive drums and tail drums are square and
parallel to the machine’s structure.
Never try to track the elevator belts by moving either the
head or tail drums out of square.
2)
The idler rollers are in slotted holes, to allow them to be
moved at a slight angle to the belt.
If the belt is moving to the left on the load (top) side, adjust
the idler on the left, at the beginning of the misalignment,
forward. This has the effect of moving the belt back towards

the centre. Alternatively, move the right hand side of the
idler back.
If this does not bring the belt sufficiently back into the
centre, move to the next idler up and adjust its position,
Carry on until the belt tracks into the middle on the head
drum.
3)
If the belt is moving off centre on the return side, and the belt
is off centre on the tail drum, move the return idlers forward
on the side the belt is moving towards.
4)
Securely lock all the idlers after the elevator belt has been
tracked. The elevator belt tracking should be checked
weekly.
Idler rollers : These have sealed for life bearings inside them and should be
checked annually to ensure that none have seized. Weekly,
the return idler should be checked to ensure that the rubber
support wheels are not in contact with the cross lugs. The
cross lugs can be pulled off by being constantly hitting
against these rubber wheels, causing then to be stripped
from the belt surface.
Adjustment of front hopper sensors:
The level switch / float, will detect when the front hopper is
full and stop the elevator belt on that side. The position of
the arm and the angle at which it will switch the elevator belt
ON/OFF is adjustable.
The vertical position of the float can be adjusted by moving
the arm through the pivot assemble. The higher the float
position the greater the front hopper will fill before the belts
are stopped. The angle at which the switch is ON and OFF is
adjusted by slackening the pilot assembly on the splined
shaft of the switch and moving it to a new position so that
the switch is off in the vertical position and switches on at
the correct angle to sense the hopper is full. Re-secure the
pivot assembly when the angle of the switch and float is
correct.
Note
The switch is open (OFF) when the elevators are operating
and closed (ON) when the elevators are stopped.

MAINTENANCE
The folding side hinges should be lubricated weekly. The hinge pin can be
removed rearwards to release the folding side. The rubber around the back
of the hopper needs replacing when it becomes damaged.
The elevator belt aperture and rear flap rubber needs changing only when
heavily worn.

Tow Hook
SPECIFICATION
Supported on a rubber/elastic bush to allow angular movement and to
absorb shock loads, the bush will gradually ‘relax’ causing the tow hook’s
position to drop.
The tow hook is operated by a two way hydraulic ram.
To Re-Position Hook
To re-position the hook when the bush has relaxed, slacken the three cap
head set screws, holding the bush into the bracket, until the bush outer
ring can rotate inside the bracket. Lift the tow hook until positioned
correctly and re secure the cap head screws.
When the rubber / elastic bush no longer maintains its flexibility, it will
require replacement.
See section 4.4 for details of tow hook truck attachment layout.
