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 into the vacant coolant valve seat.
•
When temperatures fall below 32° F (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.
ARE adaptor
FIG. 5 – ARE ADAPTOR
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 fi xing screws, etc.
