3.8) SPECIAL SPIRAL TWIST BITS
Using these bits guarantees optimum performance during the drilling operations. As a
rule, under normal conditions, a spiral bit can drill 70-100 holes, depending on the hard-
ness of the rail.

For tools of other types, check the dimensional compatibility (particularly the size of the attachment and the length).
3.9) "LR2" LUBROCOOLER CONCENTRATE, 1 or 5 gallons for optimum
operation of both the broach cutters and the spiral bits.
This product of vegetable origin, to be watered down in the percentage
95% water, 5% oil, will provide a white colour mixture very effective for
the drilling operations resulting in no heating at the rail or the drilling
machines.
3.10) "LR 3" ANTIFREEZE CONCENTRATE of 1 or 5 gallons added
to the lubrocooling mixture with the right percentage will maintain the
lubrocooling mixture fl uid in negative temperature consitions.

13.1.3) Checking the bolts
Check and retighten all bolts.
13.1.4) Lubrication (Ref. to Figs. 27 and 28)
Lubricate the spindle support housing by means of the appropriate lubricator (18), the
screw (07) of the clamping device with moving arm DBG-Y.
13.1.5) Cleaning of the coolant fi lter (Ref. to Fig. 25)
The coolant system of the drilling machine is provided with anti-impurity fi lter; should an
evident decrease of the fl ow of the lubrocoolant be verifi ed, it could be necessary to clean
it in the following way:
– Using a 14mm key, unscrew the coupling (02).
– Extract the fi lter and clean it carefully.
– Reassemble the fi lter into the coupling (02) as shown in the Fig. 25, fully tighten the
coupling.
13.2) ORDINARY MAINTENANCE OF THE MOTOR
Every 50 hours of operation
13.2.1) Changing the brushes (Ref. to Fig. 26)
After disconnecting the power plug check the degree of wear of the brushes; if necessary
replace them by proceeding as follows:
– Unscrew with a screwdriver the two screws located underneath the protective covers.
– Remove the two protective covers.
– Replace the brushes.
– Reassemble the two protective covers.
– Tighten the locking screws.
