– The special spiral bits in the PE range allow automatic cooling by means of the SR5000 unit sup-
plied with the drilling machine.
– All spiral bits in the PE range allow drilling of thicknesses up to 45 mm.
The drilling tools indicated in the table guarantee optimum results. For tools of other types,
check the dimensional compatibility (particularly the size of the attachment and the length).
3.10) LR2 BIODEGRADABLE LUBROCOOLANT
3 litre container to be used in a 5-10 % solution, for optimum operation of both broach
cutters and spiral bits.
3.11) LR3 ANTIFREEZE CONCENTRATE
3 litre added to the lubrocoolant mixture in the right concentration will
maintain the lubrocoolant mixture fl uid in negative temperature conditions.

13.2) ORDINARY MAINTENANCE OF THE COMBUSTION ENGINE
Every 100 hours of operation
13.2.1) Fuel fi lter cleaning (Ref. to Fig. 28)
– Check that the engine oil fi ller cap is tightened
securely.
– Remove the fuel fi ller cap, and drain the fuel
into an approved gasoline container by tipping
the engine toward the fuel fi ller neck.
– Pull the fuel fi lter out through the fuel fi ller neck
by hooking the black fuel tube with a piece of
wire, such as a partly straightened paper clip.
– Inspect the fuel fi lter. If the fuel fi lter is dirty,
wash it gently with nonfl ammable or high fl ash
point solvent. If the fuel fi lter is excessively
dirty, replace it.
– Remove water and dirt from inside the fuel tank
by rinsing it out with non-fl ammable or high
fl ash point solvent.
Adaptor
– Insert the fuel fi lter into the fuel tank and tighten
ref.
the fuel fi ller cap securely.
Improper use of solvents can result in fi re
or explosion.
Every 3 months or 25 hours of operation
13.2.2) Air fi lter cleaning (Ref. to Fig. 29)
– Press the latch tab (A) on the top of the air cleaner
cover and remove the cover.
– Clean the fi lter element in warm soapy water, rinse
and allow to dry thoroughly, or clean in non fl am-
mable solvent and allow to dry.
– Dip the fi lter element in clean engine oil, then
squeeze out all excess oil.
– Wipe dirt from the air cleaner body and cover,
using a moist rag. Be careful to prevent dirt from
entering the carburettor.
– Reinstall the fi lter element and air cleaner
cover.
Always replace damaged fi lter elements.
Operating in dusty condition may require more
frequent maintenance than above.
Do not operate the engine with air fi lter re-
3l
moved.
