only when the battery provided and rainproof cover are correctly used together.
Before use, always check:
• The precise positioning of the rainproof cover, especially around the battery area.
• The integrity of the rainproof cover, for example, the absence of cuts or abrasions; a damaged
cover must be replaced in order to avoid ingress of water and moisture into the motor and / or
the battery.
– When operating, stand in a stable, secure position and grip the drill firmly.
Be sure to work in good light conditions or with sufficient artificial lighting.
During drilling keep your hands outside the danger area.
Always wear protective glasses and working gloves.
Avoid wearing clothes which may present a risk to personal safety.
– Always remove the battery when servicing the drill, before performing any work in the area of
the spindle e.g removing cutting tools (broach cutters, spiral bits) assembling positioning tem-
plates, maintenance or cleaning.

The spindle is advanced by moving the lever (36) (Ref.
to Fig. a).
The lever is fitted with a release pawl (39) (Ref. to Fig. b).
which, when pressed, renders it independent of the hub
and hence the spindle;
The operator can therefore:
easily change the angular position of the lever without
movement of the spindle.
retrieve the stroke in phase of drilling (Ref. to Fig. c).
4.1) Adjustment of the advance lever
The movement of the lever must never be loose, for adjust-
ment proceed to tighten it by loading the cup springs by
means of the associated self-locking nut, after removing
the protective cap.

b) - With the release pawl (39) pressed, the lever is released
from its hub and can repeat the previous travel without
the spindle moving.
c) - With the hub released, moving the lever towards
the operator produces a corresponding advance

Two high efficiency LED worklights enable efficient illumination of the drilling area (e.g. in tunnels or outdoors at
night).
Use the ON/OFF switch (17) on the side of the motor switch to activate or deactivate the automatic illumination of
the lights on the front of the motor.
ON position: the lights turn on automatically at start-up and turn off automatically 20 seconds after the motor is
switched off.
OFF position: no automatic illumination, the lights remain off.
The motor switch (15) is placed on the motor in an easily visible position and can
be rapidly activated in case of emergency.
It is a tilt switch and provided with an interlock device to avoid unintentional start-ups.
The switch has two specific functions:
Start / Stop of the drill:
slide the interlock device forward (1) and
press the switch into operating position (2).
To stop the drill, return the switch to its cen-
tral position (0).

8. "DRILLING ASSISTANCE" FUNCTION
Thedrillfeaturesa circuitboardthatconstantlymonitorstheoperating
voltage, motor and battery current. This enables optimisation of the
electric motor's capability and consequently enables best possible
battery life, guaranteeing security and reliability.
An LED indicator is placed in an easily visible position on the motor
and has the dual function of:
Providing "Drilling Assistance" to the operator (Ref. to § 8).
Indicating any errors or operational anomalies of the machine
(Ref. to § 13).
The “drilling assistance” function has been developed and optimised for use with CEMBRE CY range Broach
Cutters (diameter from19 to 32 mm, ref. to § 3.10), on 800 and 900 quality steel rails (UIC 860.0).
The multiplicity of variables (hardness of the rail, typology and sharpness of the cutting tool in use) does
not permit all possible application criteria to be covered.
The “drilling assistance” function is not optimised for cutting tools of other manufacturers.
By responding to the changes in colour of the LED indicators (Ref. toTABLE 1), the operator is able to apply optimum
force on the spindle lever so as to obtain the maximum possible output, required to achieve predictable drilling
times by standard methods.

Batteries are supplied with a charge ≤ 30%. To maximise energy level, it is necessary to fully recharge them
before use.
Only use the battery charger supplied with the drill.
Charge the battery by following the instructions provided in the battery charger manual, approximately
120 minutes are required to charge a fully depleted battery with ASC 145 fast charger.
Before inserting the battery, ensure that the Motor switch is in the central OFF position “0”: if not, the yel-
low LED on the indicator will be lit with a subsequent electronic lock of the drill (Ref. to §12) in order to avoid
involuntary start-ups. To restore function, remove the battery, move the Motor switch to the OFF “0” posi-
tion and reinsert the battery.
The battery is equipped with LED indicators that indicate the remaining battery life at any time by pressing the
adjacent button (C):
4 LEDs illuminated: fully charged
2 LEDs illuminated: 50 % capacity
1 LED flashing: minimum charge, the battery is almost depleted and needs
to be charged.The electronics protect the battery from any damage caused
by complete depletion.
Continuous overload causes deactivation due to overheating. In such a
case, allow the battery to cool down; if the battery feels hot to the touch,
it can be cooled down more quickly by inserting it into the relevant “AIR
COOLED”battery charger.
A completely charged battery provides 100% of its energy between -20°C
and + 50°C.
Removal of the battery:
- Retract the upper and lower parts of the rainproof cover (16) to expose the battery (Fig. a).
- Unlock the battery by the button (P) and remove it in an upwards direction (Fig. b).
Insertion of the battery:
- Retract the rainproof cover (16) and slide the battery down the guides until in place and locked by the button
(P) (Fig. b).
- Carefully and precisely reposition the rainproof cover (16) so as to cover the upper and lower parts of the bat-
tery (Fig. c).

Connect the SR5000 coolant unit to the attachment (35) on the drill by means of its quick-coupling (03) by passing
the hose through the O-Ring (36) so as to support the tap (02).
The use of the lubrocoolant supplied by CEMBRE, in the recommended concentrations, guarantees optimum life
of the cutting 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.
To fill tank with lubrocoolant, turn handle anticlockwise approximately 2 turns to releas handle locking mechanism.
Remove handle/piston assembly from tank.
When drilling with a broach cutter, the delivery and shut-off of the lubrocoolant are controlled 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).
When the tank is not under pressure, check that the
maximum pressure valve is screwed right down.
Avoid leaving the SR5000 coolant tank under pressure
or exposed to sunlight for long periods of time.

After removing or inserting the battery make sure of the precise repositioning
of the rainproof cover.
Check that the cover adheres laterally and covers the upper and lower parts of
the battery.
Wrong positioning of the rainproof cover can cause water ingress resulting in
damage to the motor and/or battery.
9.1) Using the battery charger
Carefully follow the instructions in the battery charger user manual.

The drill is equipped with a coolant attachment valve (35) and a vent valve (20).
If under certain operating circumstances they need to be interchanged, proceed as follows:
Using a 17 mm spanner unscrew the vent valve from its seat.
Remove the protection plate and using the 4 mm T-handle Allen key provided with the drill, remove the appro-
priate coolant valve from its seat and fit into the vent valve seat, then assemble the protection plate.
Fit the vent valve into the removed 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:
Disconnect the quick-coupling (03) from the coolant at-
tachment (35) on the drilling machine.
Tilt the machine so that the coolant attachment is at its
lowest point allowing natural drainage.
Operate the advancing lever (36) to advance and retract
the drilling spindle.
Gently shake the machine to expel all fluid.
ARE adapter
Adapter ARE
The ARE adapter is inserted in the quick-coupling (35) of the tank tube of the SR5000, 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.
To clean various parts of the drill, by means of the lubrocoolant pressure jet, e.g. the tool clamping seat in the
spindle shaft, seats for the template fixing screws, etc.

11. PREPARING THE RAIL DRILL
Always remove the battery when servicing the drill, before removing the cutting tools (broach cutters, spiral
bits and positioning templates etc).
Be careful of the broach cutter’s sharp edges. Always wear work gloves to avoid injury.
The drill spindle is factory-set to operate with CEMBRE CY range broach cutters fitted with Quick push/turn
coupling; use of broach cutters and twist drill bits fitted with Weldon shank only requires disassembly of the
transverse pin in the spindle (Ref. to §11.2).
11.1) Assembling broach cutters with Quick push/turn shank
Using the drive lever, turn the spindle so as to facilitate operation.
Insert the correct guide bit into the broach cutter (Ref. to § 3.10), from the shank end.
Insert the broach cutter into the spindle by positioning it so that the side flat lines up with the transverse pin
within the spindle, then rotate in a clockwise direction (2); the broach cutter will be locked without the need to
tighten the two grub screws (18).
Check that the guide bit slides freely by applying slight pressure on it.
To disassemble the broach cutter, turn in an anticlockwise direction and remove it from the spindle.
Before fitting, always check that the broach cutter is provided with the O-ring to ensure it secures correctly.
It is also possible to assemble broach cutters with Weldon shanks (Ref. to § 11.2).

11.2) Assembling broach cutters with Weldon shank
Using the spindle lever, advance the spindle to
make the transverse threaded pin accessible;
if it is not in a easily-accessible position, insert
the battery and slide the Motor switch forward
(indexing function (Ref. to § 5) to make the pin
visible, then remove the battery.
With the 4mm T-handle Allen key, remove the
transverse threaded pin from the spindle (1) and
screw it into the "parking hole" in the clamping
device.
To protect the transverse threaded pin, tightly screw it into the “parking hole” (2) on the clamping device;
A spare pin is available in the ACCESSORIES KIT.
Using the advance lever, position the spindle shaft so that both grub screws (18) become accessible.
If necessary, insert the battery, slide the Motor switch forward to generate successive rotations of the spindle
(indexing function (Ref. to § 5), making the grub screws (18) visible, then remove the battery.
Insert the correct guide bit into the broach cutter (Ref. to § 3.10), from the shank end.
Unscrew grub screws (18) and insert the broach cutter into the spindle (1) in such a way that the two engaging
dogs on the shank of the broach cutter correspond to the grub screws.
Grub screws (18) have stops that prevent their complete unscrewing, do not force them past this stop.
Lock the broach cutter by fully tightening the screws using the 4 mm T-handle Allen key (2).
Check that the guide bit slides freely by applying slight pressure on it.
