Servicing
Switch the engine off and let it cool down. Pull out the
mains plug or close the fuel valve.
Check the general condition of the machine. Check
for loose screws, misalignment or jamming of moving
parts, part breakages and other conditions that could
impair safe operation.
Remove all foreign objects and other materials that
have collected on the saw blade and on the unit.
Clean the machine after every use. Then use a
high-quality, low-viscosity machine oil to lubricate all
moving parts.
m Never use a high-pressure cleaner to clean
your machine. Water can penetrate sealed areas
of the machine and the transmission housing
and cause damage to spindles, gear wheels,
bearings or the engine. The use of high-pressure
cleaners shortens the service life and reduces
the ease of maintenance.
Experienced craftsmen can carry out small repairs
on the machine themselves.
• Check the saw blade at regular intervals. Only
use saw blades that are free of cracks and not de-
formed. Only use tools that comply with the Euro-
pean standard DIN EN 847-1.
• Replace worn swivel frame bearings immediately.
• Check all safety devices after all maintenance or
cleaning work.
• Check that no tools or miscellaneous parts are on
or in the machine before putting it back into oper-
ation.
• Remove any sawdust accumulations that may arise
at the discharge.
