4. SPINDLE ADVANCE LEVER

The spindle is advanced by moving the lever (36) (Ref. to Fig. a).

The lever is ﬁ tted 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).

a) - Moving the lever (36) towards the operator produces a corresponding advance of the spindle.

b) - With the release pawl (39) pressed, the lever is released from its hub and can repeat the previous travel without the spindle moving.

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.

c) - With the hub released, moving the lever towards the operator produces a corresponding advance of this spindle.

self-locking nut

5. MOTOR ON/OFF SWITCH (EMERGENCY)

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 speciﬁ c 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 central position (0).

“Indexing” function:

is useful for easy access to the grub screws on the drill spindle. With one ﬁ nger, keep the interlock device forward (1) and with another repeatedly push the switch down (2).

With each press of the switch, the spindle rotates by 10°.

OFF in

central position

6. LED WORKLIGHTS ON/OFF SWITCH

Two high eﬃ ciency LED worklights enable eﬃ cient illumination of the drilling area (e.g. in tunnels or outdoors at night). Use the ON/OFF switch (16) 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 .

7. LED INDICATOR

The drill features a circuit board that constantly monitors the operating

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).

LED indicator

8. "DRILLING ASSISTANCE" FUNCTION

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. to TABLE 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.

9. RECHARGEABLE BATTERY

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 50-60 minutes are required to charge a fully depleted battery with ASC ULTRA 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” position 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 ﬂ ashing: 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 -15°C and + 50°C.

Insertion of the battery:

slide it down the guides until in place and locked.

9.1) Using the battery charger

Carefully follow the instructions in the battery charger user manual.

Removal of the battery:

unlock it by pressing the button

(P) and remove it in an upwards direction.

10. SR5000 COOLANT UNIT

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 ﬁ ll tank with lubrocoolant, turn handle anticlockwise approximately 2 turns to release 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 ﬂ uid must be eﬀ ec ted 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.

Detail of the

max pressure valve

01 – SR5000 coolant unit 02 – Tap 03 – Quick-coupling 17 – Vent valve 35 – Attachment coupling 36 – O-Ring

The drill is equipped with a coolant attachment valve (35) and a vent valve (17).

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 ﬁ t 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

attachment (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 ﬂ uid.

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 ﬁ xing 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 ﬁ tted with Quick push/turn

coupling; use of broach cutters and twist drill bits ﬁ tted 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.

guide bits PP or PPL

Insert the broach cutter into the spindle by positioning it so that the side ﬂ at 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 ﬁ tting, 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).

11.4) Assembling terminations on DBG-F2 clamping device

TDB 1, TDB 6 and TDB 3 terminations of the DBG-F2 device, with moving arm, have been designed for adaptation to the diﬀ erent operating conditions on rails and track ﬁ ttings; their assembly/disassembly is shown in the Figures. Normally they are mounted in the central holes of the clamping device. The two adjacent holes allow to adapt them to a variety of clamping conditions.

When disassembling the TDB 6 termination ﬁ rst remove the pivot and central bush, ensuring that it is slid

away downwards without acting on the holding plate.

Over-advancing the spindle after drilling must be avoided when using the TDB 1 and TDB3 terminations.

When assembling the TDB 3 termination ensure that the positioning pawl is pointing downward in relation

to the bolt.

11.6) Assembling positioning templates

Only Cembre positioning templates and jigs are to be used with the rail drill.

Choose the correct positioning template for the rail proﬁ le to be drilled.

Place the positioning template on to the front plate of the drill, aligning the two reference pins with the holes in the template.

MPAF.. MPSR and MPAU positioning templates are secured to the front plate by means of two screws M6x16 by using the 5 mm Allen key supplied in the ACCESSORIES KIT of the drill. For special positioning templates (e.g MPD... & MPR...) use the two screws M6x25.

11.7) Fitting “double-sided'” templates

Compared to the templates for positioning rail drills, the KPAF "double-sided templates" are equipped with a double

proﬁ le that enables positioning of the drill on two diﬀ erent types of rail by simply inverting them.

They are ﬁ xed on the sides of the front plate.

The inserts permit the drill to be positioned on

two types of rail with a speciﬁ c drilling axis.

During ﬁ tting, ensure that the inserts are facing

the correct side, corresponding to the rail being

drilled.

Rotate both inserts to the same

side, suited to the proﬁ le of the rail

being drilled.

Mount inserts onto the sides of the

drill’s front plate by ensuring that

the pins (S) match the correspond-



ing holes in the inserts (Ref. to Fig. a).

11.8) Clamping the drill to the rail web

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 moving arm (17) (Ref. to Fig. a); use the hand wheel (12) to completely open the moving arm.

Place the drill on the rail at the point to be drilled and clamp it by tightening the hand-wheel fully down (12): the positioning template will automatically position the cutting tool in line with the designated axis; if precise positioning is necessary to the longitudinal track axis, use the reference pin (01).

For rapid drill release, simply back-oﬀ the hand-wheel (12) by approximately two complete turns, and while supporting the drill by its handle (09), pull the hand-wheel towards you. The threaded bush (39) will disengage the seat (A) in the moving arm (17) (Ref. to Fig. b) 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 simpliﬁ ed: after positioning the drill at the point to be drilled, simply push the hand-wheel forwards so that the threaded bush (39) engages the seat (A) of the moving arm. Now, a few turns on the hand-wheel will be suﬃ cient to engage the drill correctly on the rail.

When the drill is ﬁ tted with “long” type broach cutter (for drilling thickness up to 50 mm) take care to posi tion the drill on the rail by keeping the spindle fully withdrawn.

12. DRILLING OPERATION

To optimise battery charge and for safety reasons, the drill is equipped with a timer.

If drilling operations continue for more than 120 seconds, the motor automatically stops.

To re-start it, it is suﬃ cient to operate the Motor switch.

Switch on the cooling system before starting the drill (§ 10).

Avoid pressure jolts on the advancing lever during drilling.

When drilling close to raised markings on the rail the initial pressure must be extremely light until the mar-

kings disappear, otherwise the cutter may be damaged.

Always ensure that swarf is regularly removed before starting to drill a new hole.

Incomplete locking of the machine on the rail being drilled may cause breaking or accelerated wear of the

cutting tool as well as damage to the spindle shaft bearings.

max.120 s

12.1) Drill ﬁ tted with broach cutter

The drilling sequence may be started with the drill corrected clamped to the rail (Ref. to § 11.8) than:

1) Connect the female quick-coupling of the SR5000 coolant unit to the male coupling on the drill (§ 10).

2) Open the tap ﬁ tted on the coolant unit hose.

3) Using the lever (36) bring the guide bit almost in contact with the rail (Ref. to Fig. a);

4) Keeping the release pawl (39) pressed, release the lever from its cup and return it to the initial position (Ref. to

Fig. b), which will enable the travel of the lever to be used in the most advantageous way (Ref. to Fig. c).

FIG. a FIG. b FIG. c

5) Start the machine by pressing the Motor switch (15) as described in

the § 5. If necessary, activate switch (16) for the automatic illumination of the LED worklights.



6) Proceed to drill the hole by initially applying a light pressure on the lever,

gradually pushing it so that the green LED on the indicator display turns on (Ref. to § 8 for further details); continue this progress, avoiding any changes, so that the green LED stays il luminated for the entire drilling process; only alleviate the pressure on the lever during the exit phase. To ﬁ nish drilling, depending on the thickness being drilled, a stroke recovery may be performed by releasing the lever, as described in point 4 above.

The guide bit will enable the lubrocoolant to be discharged throughout the drilling process.

7) When drilling has been completed, fully retract the spindle, stop the machine by pressing the Motor switch in 0 position "OFF".

Any shut-oﬀ of the motor during the drilling process, combined with illumination of an LED on the indicator,

indicates the presence of a fault. In such a case refer to §13.

12.2) Drill ﬁ tted with special spiral bit

Follow the sequence described in § 12.1, 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 APED adapter or DPE spacer ﬁ tted on the spigot of the spiral bit; it must therefore

be activated, by opening the tap, before starting to drill, then switched oﬀ after drilling by closing the tap.

Normally, using twist drill bits up to Ø 13 mm (Ref. to § 3.11) does not require a force that illuminates the

green LED on the indicator.

In such a case, it is however acceptable for the WHITE LED to remain illuminated.

15. STORING THE DRILL

When work has been completed, store the drill by proceeding as follows:

Depressurise the tank of the SR5000 coolant unit (Ref. to § 10), close the tap on the hose and disconnect the

quick-coupling.

Remove the battery from the drill, thoroughly clean it with a dry cloth and place in the appropriate canvas bag

032, also suitable for the storage of the battery charger and the spare battery.

Carefully clean the drill, particularly in the spindle area, removing machining waste (swarf, etc.) and any deposits

of lubrocoolant, then fully withdraw the spindle.

Place the drill, batteries, battery charger and the SR5000 coolant unit in a sealed place free from dust, moisture

and the risk of accidental impact.

The optimum storage temperature of the batteries is between 10 ° C and 30 ° C.

For better protection Cembre recommends the use of the VAL P24 or VAL P24-CS (with wheels) plastic cases de-

signed for this purpose, which enable to store the drill blocked by means of the DBG-F2 clamping device and canvas

bags for batteries and battery charger.

Suitable side housings are also provided in this case for storing comon accessories.

16. MAINTENANCE

Before servicing or maintenance the drill, always remove the battery.

After ﬁ rst 10 operating hours, proceed with sump oil change,

as follows:

Remove oil ﬁ ller cap (07).

Remove the cap with the magnetic insert (21).

Make sure that all the oil comes out by slightly tilting the drill.

Clean up the cap (21) (see § 16.1.3).

Reassemble the cap (21).

Fill the sump with oil to the level indicator (see § 16.1.2) using the oil supplied (100 ml) in the ACCESSORIES KIT of the rail drill.

Replace the ﬁ ller cap (07).

Ensure that disposal of used oil is in accordance with current

legislation.

Daily maintenance is indispensable to keep the machine in best condition. Maintenance not carried out properly, or carried out by unauthorised or unqualiﬁ ed personnel can noticeably reduce the machine’s eﬃ cienc y and increase the risk of accidents and serious injury. The maintenance procedures described may be carried out by the operator. For any eventual ﬁ ne tuning or repairs, return to Cembre (Ref. to § 17).

16.1) ORDINARY MAINTENANCE OF THE DRILL

Daily

Before use, check:

The drill in its entirety (securing of various components).

The correct operation and integrity of the Motor switch (Ref. to § 5).

The integrity and charge of the batteries.

After use:

Clean the machine of any contaminants and swarf by using a clean rag.

Thoroughly clean the spindle area and the drilling machine of any swarf.

Clean the air intake on the side of the motor if it is clogged.

Every 20 hours of operation

16.1.1) Check screws

Check and re-tighten all screws where necessary.

16.1.2) Top up oil

With the drill placed on a ﬂ at surface, check the oil level in the crankcase by looking through the appropriate transparent inspection cover (13). The level must be approximately half way up the cover; if the level is low top up the oil by unscrewing the cover (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.

16.1.3) Remove metallic residues from the crankcase

When the drill is positioned as shown in Figure unscrew the appropriate cap, with magnetic insert (21) on which any metallic residue will have collected. Carefully clean the magnetic insert with a clean rag and screw it back in the appropriate housing.

Every 50 hours of operation

16.1.4) Lubricate

Lubricate the spindle support housing by means of the appropriate lubricator (18), the screw (17) of the clamping device with moving arm.

16.1.5) Clean coolant ﬁ lter

The coolant circuit of the drilling machine is provided with an anti-impurity ﬁ lter; should an evident decrease of the ﬂ ow of the lubrocoolant occur, it could be necessary to clean the ﬁ lter in the following way:

Using a 14 mm key, unscrew the coupling (02). Extract the ﬁ lter and clean it carefully. Reassemble the filter into the coupling (02) as

shown in the ﬁ gure.

Reposition and fully tighten the coupling (02).

anti-impurity ﬁ lter

16.2) SPECIAL MAINTENANCE OF THE DRILL

Special maintenance operations require the intervention of qualiﬁ ed personnel only, please contact Cembre (Ref. to § 17)

APPENDIX “A” Factors which inﬂ uence the number of holes that can be made according to the cutting tool

used.

– Hardness of the material to be drilled. – Thickness to be drilled. – Stability of the drill clamp and correct assembly of the cutter/bit. – Suitable lubrocooling (lubrication/cooling) to keep the temperature of the cutter low so as not to compromise

the eﬃ ciency of the cutting edges, whilst at the same time facilitating the removal of the swarf. – The contact time of the cutting edge with the material and the force exerted on it; bear in mind that drilling the hole in the shortest time may mean excessive pressure has been applied to the cutter thus reducing its ef ﬁ ciency. The "drilling assistance" function allows the operator to work in a manner which optimises force and time thereby maximising cutter eﬃ ciency.

Observe these basic rules:

1) Commence drilling by exerting light pressure on the advancing lever, progressively increasing and then relaxing it only when the cutter is in the exit phase.

2) Avoid pressure jolts and only advance according to the drilling diameter to avoid scratching the material or damaging the cutting edges of the cutter/bit.

3) Remember that a cutter with eﬃ cient cutting edges requires a pressure lower than that applied to one with which a number of holes have already been made.

4) When holes are made close to raised lettering on the rails, the initial pressure must be extremely light until the markings disappear, otherwise the cutter may be damaged.

17. 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 machine to our nearest service Centre; if possible, attach a copy of the Test Certiﬁ cate supplied by Cembre together with the machine or ﬁ ll in and attach the form available in the “ASSISTANCE” section of the Cembre website.
