14.1) Regularlycheck forcorrect tightening(torque) ofthe fixingscrews ofthe drillingtools
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.

 WARNINGS
– Before using the drill, carefully read the instructions contained in
this manual.
SAVETHESEINSTRUCTIONS:thismanualcontainsimportantsafety
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.
– Avoid wearing clothes which may present a risk to personal safety.
14. WARNINGS
15. RETURN TO Cembre FOR OVERHAUL
In the case of a breakdown, contact our Area Agent who will advise you on the problem
andgive you the necessary instructionsonhow to dispatch the drilltoour 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”
Factorswhichinfluencethenumberofholesthatcanbemadeaccordingtothetoolused:
– 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) tokeepthe temperatureofthe toollowso
as not to compromise the efficiency of the cutting edges, whilst at the same time facili-
tating 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, progres-
sively increasing and then relaxing it when the tool is in the exit phase.
2) Avoidpressuresurges andadvanceaccordingtothediameterofthedrillingdiameter,
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 pres-
sure 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.

FIG. 30 – SPARK PLUG CLEANING
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.
– Disconnectthesparkplugwireleadandremovethesparkplugwiththekeysupplied.
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.
– Wheninstallinganewsparkplug,tighten1/2
turn with the key to compress the washer.
When reinstalling the original spark plug,
tighten1/8-1/4turn withthe keytocompress
the washer.
A loose spark plug can overheat and
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.
13.2.4) Check engine oil (each use) (Ref. to Fig. 31)
Before checking or refilling engine oil, be sure the machine is located on a stable, level
surface and stopped.
– Remove the oil filler cap/dipstick and wipe it clean.
– Insert the oil filler cap/dipstick without screwing it into the oil filler neck, then remove it
to check the oil level shown on the dipstick.
If the oil level is near or below the lower limit mark on the dipstick, fill to the bottom edge
of the oil fill hole with the recommended oil (see § 1).
– Change oil if it is contaminated.
– Wipe off any spilled oil before starting the engine.
– Reinstall the oil filler cap/dipstick and tighten securely.

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.
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.

max pressure valve
FIG. 3 – COOLANT UNIT
The type SR5000 coolant unit consists of a tank complete with tube and maximum pres-
sure 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).
Thedeliveryandshut-offofthelubrocoolantarecontrolledautomatically,whendrill-
ing 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.
Warning:
● When the tank is not under pressure, check that the bush on the maximum pres-
sure 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.

When the drill is positioned as shown in Fig. 26
unscrew the cap with magnetic insert (28) on
which any metal residues present in the oil will
have collected. Carefully clean the magnetic
insert with a clean cloth and screw it back into
the appropriate housing.

FIG. 4
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).
– Makesurethatalltheoilcomesoutbytiltingslightly
the drilling machine in order to make the operation
easier.
– Clean the cap (28) (see § 13.1.2).
– 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).
Ensure that disposal of used oil is
in accordance with current legislation.
13.1) ORDINARY MAINTENANCE OF THE DRILL
Every 20 hours of operation
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.
● 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
causedamage to theseals contained in
the drill coolant system.
It is therefore advisable, when storing
the drilling machine, to empty the lu-
brocoolant 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.

The spindle is advanced by moving the
lever (36) (See Fig. 6 a). The lever is fit-
ted with a release pawl (39) which, when
pressed, renders it independent of the
hub and hence the spindle; the opera-
tor can therefore easily vary the angular
positionof thelever withoutmovementof
the spindle (Fig.6).
6c - With the hub released, moving the lever
towards the operator produces a cor-
responding advance of this spindle.
6a - Moving the lever (36) towards the

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 as-
sociated self-locking nut, after removing the
protective cap (see Fig. 7).

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.
12.4) Place the drill and the SR5000 cooling unit in a sealed place free from dust, mois-
ture 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.Asuitable housing is also provided in this VAL LD for the
VAL MPA case containing the most commonly used accessories.

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).
– Forrapiddrillrelease,simplyback-offthehand-wheel(12)byapproximatelytwocomplete
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.
Inthisway,theoperatorcanrapidlyremovethemachinefromthetrackincaseofdanger,
