4. COOLANT UNIT TYPE SR5000 (Ref. to Fig. 3)
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, from the position of 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.
Warning:
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.

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 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 (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.

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.

5. SPINDLE ADVANCE LEVER (Ref. to Fig. 6)
The spindle is advanced by moving the lever
(36) (see Fig. 6a). 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).
FIG. 6
6b - With the release pawl (39) pressed, the lever is
released from its hub and can repeat the pre vious travel without the spindle moving.
5.1) Adjustment of the advance lever
The movement of the lever must never be loose,
for adjustment proceed to tighten it by loading
the cup springs by means of the associated
self-locking nut, after removing the protective
cap (see Fig. 7).
6a - Moving the lever (36) towards the operator
produces a corresponding advance of the
spindle.
6c - With the hub released, moving the lever
towards the operator produces a corre sponding advance of this spindle.

6. PREPARING THE RAIL DRILL
DISCONNECT always the power supply 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.
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.

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).
13
6.2.2) Insert into the spindle shaft, the DPE spacer required to activate the coolant system.
If it is necessary to use an APE... adaptor the bit must first be fitted in 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 againt 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 hexagon key.

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:
7.4.1) Withdraw the spindle shaft (07) completely by means of the lever (36).
7.4.2) Insert the threaded bush (39) of screw (11) into its seat (A) in the mobile arm (17) (see
detail in Fig. 17); use the hand-wheel (12) to completely open the mobile arm.
7.4.3) Place the drill on the track at the point to be drilled and clamp it by tightening the handwheel 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 (01).
7.4.4) 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 hand-wheel 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 forwards 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.

8. DRILLING (Ref. to Figs. 17-18)
N.B.: make sure the mains voltage corresponds to that on the drill rating plate.
N.B.: switch on the cooling system before starting the drill (§ 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 (12)
on the drill.
8.1.2) Open the tap (02) fitted onn the coolant unit hose.
8.1.3) Using the lever (36) bring the guide bit almost in contact with the rail (Fig. 17a); keeping
the release pawl (39) pressed, release the lever from its cup and return it to the initial position
(Fig. 17b), which will enable the travel of the lever (36) to be used in the most advantageous way.
Fig. 17a
Fig. 17b

8.1.4) Connect the electric plug and press the automatic switch (position "I") (Fig. 17d)
CAUTION: the automatic switch is equipped with
protection against motor overheating and with an underpower relay; should the motor overheat or there is a fall
in voltage below the relay cut-out setting, the switch will
move into the "0" position. At this stage, if the conditions
are correct, the switch will have to be re-set manually.

8.1.5) ONLY FOR LD-4EF DRILL
Set the motor speed, by means of the selector
switch under the automatic switch (see Fig.
17e), in correlation to the diameter of the hole
to be. We suggest to use the standard speed
(280 rpm) for holes smaller than ø 28 mm and
the lower speed (250 rpm) for holes between
dia 28 and 40 mm inclusive.
ONLY FOR LD-4EF DRILL:

SPEED CHANGE SWITCH
8.1.6) 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.
8.1.7) The guide bit will enable the lubrocoolant to be discharged throughout the drilling
process.
8.1.8) When drilling has been completed, fully retract the spindle, stop the motor by pressing the automatic switch (position " 0 "), and make sure that drilling swarf is removed before
recommencing drilling.
8.1.9) After drilling it is advisable to remove all swarf from the tool 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.

10. STORING THE DRILL
When work has been completed, store the drill by proceeding as follows:
10.1) Depressurise the tank of the SR5000 coolant unit (see § 4), close the tap (02) on the hose
and disconnect the quick-coupling (03).
10.2) Carefully clean the drill, particularly in the spindle area, removing machining waste (swarf,
etc.) and any deposits of lubrocoolant.
10.3) Fully withdraw the spindle.
10.4) Place the drill and the SR5000 coolant 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 § 3.4), which enables the drill to be inserted thanks to the DBG-F2 clamping
device, and to be locked in the case. Suitable housings are also provided in this case for the DBSN
clamping device and the VAL MPA tool case.

11. MAINTENANCE
Before servicing or maintenance, stop the motor and disconnect the plug
from the electric source.
After first 10 operating hours, proceed with sump oil
change, as follows:
(Ref. to Fig. 26a and 26b)
– Remove the cap with the magnetic insert (21).
– Remove oil filler cap (07).
– Make sure that all the oil comes out by slightly tilting
the drill.
– Clean up the cap (21) (see § 11.1.2).
– Reassemble the cap (21).
– Fill the sump with oil to the level indicator (see § 11.1.1)
using the oil supplied with the drilling machine; it will
be necessary to use about 140 ml oil.
– Replace the filler cap (07).
07
Ensure that disposal of used oil is in
accordance with current legislation.
11.1) ORDINARY MAINTENANCE OF THE DRILL
Every 20 hours of operation
11.1.1) Topping up oil (Ref. to Figs. 26a and 26b)
With the drill switched off and placed on a flat 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.

11.1.2) Removal of 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
11.1.3) Checking of screws
– Check and re-tighten all screws where necessary.
11.1.4) Lubrication
Lubricate the spindle support housing by means of the appropriate lubricator (35), the screw of
the clamping device with moving arm, DBG-F2 and DBG-LF2.
11.1.5) Coolant filter cleaning (Ref. to Fig. 27)
The coolant circuit of the drilling machine is provided with anti-impurity filter; should an evident
decrease of the flow of the lubrocoolant occur, it could be necessary to clean the filter in the
following way:
– Using a 14 mm 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 and fully tighten the
coupling.

11.3) SPECIAL MAINTENANCE OF THE DRILL
The special maintenance operations require the intervention of qualified personnel only, Please
contact Cembre (See § 13).
APPENDIX “A”
Factors which influence the number of holes that can be made according to the 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 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 cutter/bit with the material to be drilled;
bear in mind that the faster the hole is made the greater the efficiency.
– Observance:
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 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 tool with efficient cutting edges requires a pressure lower than that ap plied to one with which a certain number of holes have already been made.
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.

Protection of operators against risksof exposure to noise during work.
Cembre drills type LD-2E and LD-2E-110 are designed and constructed according to EEC
directives 80/1107 and 86/188 relating to the protection of operators against risks arising from
exposure to chemical, physical and biological agents during work, and with particular regard to
the risk of exposure to noise.
This has enabled a range of drills to be manufactured for drilling rails and track equipment, at
reduced noise levels.
The degree of exposure of an operator to noise produced from this equipment depends on the
duration of the loading times and the intervals between exposures, and finally on the number
of holes made within the space of one working day.
For example, an operator using the drill correctly for making holes 19 mm in diam., with a type
RCV 190 broach cutter on rails classified as UIC 60, quality 900, producing up to 400 holes/day,
the daily personal exposure to noise, due solely to the use of the drill, is less than 80 dB (A); under
similar conditions producing 700 holes/day, the daily exposure to noise would be 82.1 dB(A).
Since noise levels vary according to the many different operating conditions, Cembre engineers
are available to give further details on the correct use of the drills.

12. WARNINGS
12.1) Always disconnect the electrical supply when working on the drill to replace cutters, bits,
positioning templates and/or end pieces for maintenance.
12.2) Regularly check for correct tightening (torque) of the fixing screws of the cutters/bits and
positioning templates.
12.3) Avoid pressure jolts on the advancing lever during drilling.
12.4) Always make sure that drilling swarf is properly removed before starting to drill a new
hole.
12.5) Incomplete clamping of the drill on the rail to be drilled may lead to the breakage or ac celerated wear of the cutter/bit and damage to the spindle shaft bearings.
12.6) If it is necessary to operate the drill without the cutter inserted, remove the locking grub
screws from the spindle shaft.
12.7) Avoid leaving the SR5000 coolant tank under pressure or exposed to sunlight for long
periods of time.
12.8) Should the DBG-F2 clamping device be removed when using the drilling machine in an
upright position, make sure that by reassembling it, the two locking screws are firmily
fastened.
