12.1) Always disconnect the electrical supply when working on the drill to replace cutters,
bits, positioning jigs and/or end pieces for maintenance.
12.2) Regularly check for correct tightening (torque) of the fi xing screws of the drilling
tools and positioning shoes.
12.3) Avoid pressure jolts on the advancing lever during drilling.
12.4) Always make sure that the 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 accelerated wear of the drilling tool 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 tank under pressure and exposed to sunlight for long
periods of time.
12.8) Should the DBG-Y clamping device be removed, make sure that by reassembling
it, the 2 locking screws with 4 washer are fi rmily fastened.

ARE adaptor
FIG. 5 – ARE ADAPTOR

03
4.1) ARE adaptor
For use with type SR5000 coolant unit. The ARE adaptor is inserted in the quick-coupling
of the tank tube (refer 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 de-
signed 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 fi xing screws, etc.
●
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 fi t 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
fl uid.
