OPERATION AND MAINTENANCE
MANUAL
WARNINGS
14. WARNINGS
– Before using the drill, carefully read the instructions contained in
this manual.
SAVE THESE INSTRUCTIONS: this manual contains important safety
and operating instructions for the drill.
– STOP THE ENGINE when servicing the drill: before removing the
broach cutters, spiral bits, positioning templates etc.
– During operation keep hands away from the danger zone.
– Always wear protective glasses and work gloves.
14.1) Regularly check for correct tightening (torque) of the fixing screws of the drilling tools
and positioning templates.
14.2) Avoid pressure jolts on the advancing lever during drilling.
14.3) Always make sure that the drilling swarf is properly removed before starting to drill
a new hole.
14.4) Incomplete clamping of the drill on the rail to be drilled may lead to the breakage or
accelerated wear of the drilling tool and damage to the spindle shaft bearings.
14.5) If it is necessary to operate the drill without the cutter inserted, remove the locking
grub screws from the spindle shaft.
14.6) Avoid leaving the SR5000 tank under pressure and exposed to sunlight for long
periods of time.
14.7) Should the DBG-F2 clamping device be removed, make sure that by reassembling
it, the two locking screws are firmly fastened.
– Avoid wearing clothes which may present a risk to personal safety.
15. RETURN TO Cembre FOR OVERHAUL
In the case of a breakdown, contact our Area Agent who will advise you on the problem
and give you the necessary instructions on how to dispatch the drill to our nearest service
Centre; if possible, attach a copy of the Test Certificate supplied by Cembre together
with the drill or, if no other references are available, indicate the approximate purchase
date and the drill serial number.

APPENDIX “A”
Factors which influence the number of holes that can be made according to the tool used:
–
–
–
–
LD-41P
(LD–41PN + DBG-F2)
basic drill complete with
railweb clamping device
1
Hardness of the material to be drilled.
Thickness to be drilled.
Stability of the drill clamping and correct assembly of the drilling tool.
Suitable lubrocooling (lubrication/cooling) to keep the temperature of the tool low so
as not to compromise the efficiency of the cutting edges, whilst at the same time facilitating the removal of the swarf.
– Contact time of the cutting edges of the tool with the material to be drilled; bear
in mind that the faster the hole is made, the greater the efficiency.
– Observance of these basic rules:
1) Commence drilling by exerting light pressure on the advancing lever, progressively increasing and then relaxing it when the tool is in the exit phase.
2) Avoid pressure surges and advance according to the diameter of the drilling diameter,
to avoid scratching the material or damaging the cutting edges of the tool.
3) Remember that a tool with efficient cutting edges requires a lower application pressure than one that has already made a certain number of holes.
4) When holes are made close to raised lettering on the rails, commence drilling
with very light pressure until the lettering disappears, to avoid possible breakage
of the tool.
5) Bear in mind that when operating on very hard rails, as in the case of quality 1100
steel, it is advisable to increase the lubrocoolant flow rate.

13.2.3) Spark plug cleaning (Ref. to Fig. 30)
– Using a 4 mm allen key remove the fixing screw on the top of the red cover.
– Disconnect the spark plug wire lead and remove the spark plug with the key supplied.
Inspect the spark plug. Replace it if damaged or badly fouled, if the sealing washer is
in poor condition, or if the electrode is worn. Measure the spark plug electrode gap,
correct the gap if necessary by carefully bending the side electrode.
The gap should be: 0.60-0.70 mm (0.024-0.028 in).
– Install the spark plug carefully, by hand, to
avoid crossthreading.
– When installing a new spark plug, tighten 1/2
turn with the key to compress the washer.
When reinstalling the original spark plug,
tighten 1/8-1/4 turn with the key to compress
the washer.
A loose spark plug can overheat and
spark plug
damage the engine. Overtightening the
spark plug can damage the threads in
the cylinder head.
– Attach the spark plug cap to the spark plug.
Install the top cover, and tighten the fixing
screw.
– In case of plug replacement, use type NGK
CM5H, CMR5H or equivalents.

4. COOLANT UNIT TYPE SR5000
The type SR5000 coolant unit consists of a tank complete with tube and maximum pressure valve (01), fitted with a pump device for pressurisation, which must be connected to
the attachment (35) on the drill by means of its quick-coupling (03).
The delivery and shut-off of the lubrocoolant are controlled automatically, when drilling with a broach cutter, by the guide bit; when drilling with a spiral bit, delivery and
shut-off of the fluid must be effected manually by operating the tap (02). The use of
the lubrocoolant supplied by Cembre, in the recommended concentrations, guarantees
optimum use of the drilling tools.
Consumption of the lubrocoolant depends both on the variable degree of opening
of the tap (02) and the inner pressure of the tank: it is therefore advisable to open
the tap a little when the tank is at maximum pressure, while it must be fully opened
when the pressure in the tank is low.
When using the coolant system, pay careful attention to the instructions on the tank label.
28
Every 50 hours of operating
Warning:
13.1.3) Checking of screws.
– Check and re-tighten all screws where necessary.
13.1.4) Lubrication (Ref. to Figs. 33 and 34)
– Lubricate the spindle support housing by means of the appropriate lubricator (25), the
screw of the DBG-F2 clamping device.
●
When the tank is not under pressure, check that the bush on the maximum pressure valve is screwed right down.
●
To fill tank with lubrocoolant, turn handle anticlockwise approximately 2 turns to
release handle locking mechanism. Remove handle/piston assembly from tank.

13.1.5) Cleaning of coolant filter (Ref. to Fig. 27)
The coolant system of the drilling machine is provided with anti-impurity filter; should a
decrease of the flow of the lubrocoolant be noticed, it may be necessary to clean it in the
following way:
– Using a 14mm key, unscrew the coupling (02).
– Extract the filter and clean it carefully.
– Reassemble the filter into the coupling (02) as shown in the Fig. 27, fully tighten the
coupling.

● The drill is equipped with a coolant attachment valve (35) and a vent valve (17)
which are located as shown (Fig. 3).
If under certain operating circumstances they need to be interchanged, proceed
as follows:
– Using a 17 mm hexagonal spanner unscrew the vent valve from its seat.
– Using the 4 mm allen key provided with the drill, remove the appropriate coolant
valve from its seat and fit into the vent valve seat.
– Fit the vent valve into the vacant coolant valve seat.
● When temperatures fall below 0° C the
lubrocoolant may freeze which could
cause damage to the seals contained in
the drill coolant system.
It is therefore advisable, when storing
the drilling machine, to empty the lubrocoolant system completely.
Proceed as follows (Fig. 4):
– Disconnect the quick coupling (03) from
the coolant attachment (35) on the
drilling machine.
– Tilt the machine so that the coolant
attachment is at its lowest point - allowing
for natural drainage.
– Operate the advancing lever (36) to advance
and retract the drilling spindle.
– Gently shake the machine to expel all fluid.
13. MAINTENANCE
Before you service or remove parts, stop the engine and allow it to cool.
Always remove the spark plug cap from spark plug when servicing
the engine to prevent accidental starting.
After the first 10 operating hours, proceed with sump oil change, as follows:
(Ref. to Figs. 25 and 25a)
– Remove the cap with the magnetic insert (28).
– Remove the oil filler cap (07).
– Make sure that all the oil comes out by tilting slightly
the drilling machine in order to make the operation
easier.
– Clean the cap (28) (see § 13.1.2).
07
– Reassemble the cap.
– Fill the oil sump to the level indicator (see § 13.1.1)
using the oil supplied with the drilling machine; it will
be necessary to use about 100 ml oil.
– Replace the oil filler cap (07).
36
Ensure that disposal of used oil is
in accordance with current legislation.

4.1) ARE adaptor
For use with type SR5000 coolant unit. The ARE adaptor is inserted in the quick-coupling
of the tank tube (Ref. to Fig. 5), it may be used to provide manual external cooling
when cutters are used to enlarge existing holes, or when using spiral bits not designed for automatic cooling.
If necessary the ARE adaptor can also be used to clean various parts of the drill, by means
of the lubrocoolant pressure jet, e.g. parts such as the tool clamping seat in the spindle
shaft, seats for the jig fixing screws, etc.

13.1.1) Topping up oil (Ref. to Figs. 25 and 25a)
With the drill switched off and placed on a flat surface,
check the oil level in the crankcase by looking through
the transparent inspection cover (19).
The level must be approximately half way up the cover;
if the level is low, top up the oil by unscrewing the cap
(07) at the top of the crankcase and adding the quantity
of oil required.
Only use the oil grade recommended in § 1.
Never use regenerated or used oil.
The oil must be clean.

12. STORING THE DRILL
5. SPINDLE ADVANCE LEVER
When work has been completed, put away the drill by proceeding as follows:
12.1) Depressurise the tank of the SR5000 cooling unit (see § 4), close the tap (02) on
the tube from the tank, and disconnect the quick-coupling (03).
12.2) Carefully clean the drill, particularly in the spindle area, removing machining waste
(swarf, etc.) and any deposits of lubricating coolant.
12.3) Fully withdraw the spindle.
The spindle is advanced by moving the
lever (36) (See Fig. 6 a). The lever is fitted with a release pawl (39) which, when
pressed, renders it independent of the
hub and hence the spindle; the operator can therefore easily vary the angular
position of the lever without movement of
the spindle (Fig.6).
36
12.4) Place the drill and the SR5000 cooling unit in a sealed place free from dust, moisture and the risk of accidental impact.
For better protection Cembre recommends the use of the VAL LD metal case designed
for this purpose (see § 3.2). The DBG-F2 moving arm device allows the drill to be
housed and locked in the case. A suitable housing is also provided in this VAL LD for the
VAL MPA case containing the most commonly used accessories.

6. PREPARING THE DRILL
STOP THE ENGINE when servicing the drill: before removing
the broach cutters, spiral bits, positioning templates etc.
6.1) Assembling broach cutters (Ref. to Figs. 8-11).
6.1.1) Insert the guide bit in the cutter from the side of the spigot.
6.1.2) Using the lever (36), position the spindle shaft (07) so that both grub screws (18)
become accessible and sufficient space is provided to insert the cutter; if necessary
rotate the spindle shaft manually and sufficiently by inserting the 4 mm male hexagon
key in the appropriate intermediate gear housing (33) in the crankcase of the drill
corresponding to the feed handle (71) (see Fig. 11).
6.1.3) Insert the cutter in the spindle shaft so that the two engaging dogs on the cutter
spigot line up with the grub screws (18).
6.1.4) Clamp the cutter by fully tightening the grub screws by means of the 4 mm male
hexagon key.
6.1.5) Check that the guide bit slides freely by applying slight pressure on it.

Before starting the engine, ensure that:
- the spindle shaft is fully retracted.
- the accelerator control lever is positioned at the low
speed position "0".
11.1) Set the engine "ON/OFF" switch to the "ON" position
(Fig. a).
11.2) Set the choke lever to the CLOSED
position;
when engine is warm or in the case of high ambient
temperatures, this lever may require setting to the OPEN
position (Fig. b).
11.3) Keeping the accelerator control lever at the low
speed position, press the priming bulb repeatedly until fuel
can be seen in the clear-plastic fuel-return tube (Fig. c).
11.4) Pull the starter grip lightly until resistance is felt, then
pull briskly (Fig. d). Return the starter grip gently.
Do not pull the rope out all the way.
Do not allow the starter grip to snap back against
the engine, return it gently to prevent damage to the
starter.
11.5) If the choke lever was moved to the CLOSED
position to start the engine, gradually move it to the OPEN
position as the engine warms up (Fig. e).
11.6) Keep the engine “warming up” for at least 3 minutes
before starting any actual drilling.
11.7) To stop the engine, set the accelerator lever at the
low speed position and allow the engine to run at low
speed for 2 or 3 minutes before stopping. Set the "ON/
OFF" switch to the "OFF" position.
NOTE: the engine will
perform at its optimum
after a "running-in" period of approximately 200
drilling operations.
6.2) Assembling spiral bits (Ref. to Figs. 9 - 11)
6.2.1) Using the advance lever, position the spindle shaft so that both grub screws become accessible and sufficient space is provided to insert the spiral bit; if necessary
rotate the spindle shaft manually and sufficiently by inserting the 4 mm male hexagon key in the appropriate intermediate gear housing in the crankcase of the drill
corresponding to the feed handle (see Fig. 11).

6.2.2) Insert into the spindle shaft, the DPE spacer required to activate the coolant system.
If it necessary to use an APE... adaptor, the bit must first be fitted into the corresponding
APE adaptor and locked with the appropriate grub screw, then the DPE spacer inserted.
Note: Adaptors type APED… (e.g. APED 135/165) do not require use of DPE spacer.
6.2.3) Insert the bit-spacer unit in the spindle shaft so that the two engaging dogs on the bit
spigot line up with the grub screws. Press the bit-spacer unit home against the
inner seat of the spindle: this will enable the DPE spacer to open the coolant
circuit (see Fig. 10).
6.2.4) Clamp the bit by fully tightening the two grub screws (18) using the 4 mm male allen
key.

8.3) Drill fitted with special spiral bit
Follow the sequence described in § 8.1, taking care to position the drill on the rail by keeping the spindle fully withdrawn. Bear in mind that the coolant circuit, instead of being
automatically opened and closed by the guide bit, is kept open at all times by the DPE
spacer fitted on the spigot of the spiral bit; it must therefore be activated, by opening the
tap (02), before starting to drill, then switched off after drilling by closing the tap.
7.4) Clamping to the rail web (Ref. to Fig. 16)
The drill has a rapid rail engagement/release mechanism and specially shaped positioning
templates for each rail type which facilitate precise and certain location of the part to be drilled.
To fully exploit the special features of the engagement device, we recommend calibrating
it to the rail type to be drilled as follows:
– Withdraw the spindle shaft (07) completely by means of the lever (36).
– Insert the threaded bush (39) of screw (11) into its seat (A) in the mobile arm (17) (see
detail in Fig. 16); use the hand-wheel (12) to completely open the mobile arm.
– Place the drill on the track at the point to be drilled and clamp it by tightening the
hand-wheel fully down (12): the positioning template will automatically position the
cutter or drill bit in line with the designated axis; if precise positioning is necessary to
the longitudinal track axis, use the reference pin (18).
– For rapid drill release, simply back-off the hand-wheel (12) by approximately two complete
turns, and while supporting the drill by its grip (09), pull the handwheel towards you. The
threaded bush (39) will disengage the seat (A) in the mobile arm (17) which will open
automatically, freeing the drill.
In this way, the operator can rapidly remove the machine from the track in case of danger,
or move on to drill another hole.
Thus, the next track engagement operation will be considerably simplified:
after positioning the drill at the point to be drilled, simply push the hand-wheel forward
so that the threaded bush engages the seat (A) of the mobile arm. Now, a few turns on the
hand-wheel will be sufficient to engage the drill correctly on the track.

Check engine oil level before operation (see § 13.2.4).
Switch on the cooling system before starting the drill (see § 4).
8.1) Drill fitted with “short” type broach cutter (for drilling thicknesses of up to 25 mm).
The drilling sequence may be started with the drill fitted with the broach cutter (§ 6.1),
clamping end piece (§ 7.1), positioning template (§ 7.3), the drill being clamped to the rail
(§ 7.4), as follows:
8.1.1) Connect the female quick-coupling of the SR5000 coolant unit to the male coupling (35) on the drill.
8.1.2) Open the tap (02) fitted on the coolant unit hose.
8.1.3) Using the lever (36) bring the guide
bit almost in contact with the rail Fig. 17a
(Fig. 17a);
keeping the release pawl (39) pressed,
release the lever from its cup and
return it to the initial position
36
(Fig. 17b), which will enable the travel
of the lever (36) to be used in the
most advantageous way.
8.1.4) Start the engine, following instructions § 11.
8.1.5) Proceed to drill by initially applying light pressure on the lever (36), increasing
the pressure progressively, avoiding jolts, and finally relieving the pressure in
the exit phase. When drilling close to raised markings on the rail the initial
pressure must be extremely light until the markings disappear, otherwise the
cutter may be damaged.
8.1.6) The guide bit will enable the lubrocoolant to be discharged throughout the drilling
process.
8.1.7) When drilling has been completed, fully retract the spindle, stop the motor by
pressing the switch to "OFF" position, and make sure that drilling swarf is removed
before recommencing drilling.
8.1.8) After drilling it is advisable to remove with the brush all swarf from the broach cutter
or spiral bit and spindle area.
8.2) Drill fitted with “long” type broach cutter (for drilling thicknesses of up to 50 mm).
Follow the sequence described in § 8.1, taking care to position the drill on the rail by keeping
the spindle fully withdrawn.
