WARNING
57
If resin residue is to be removed or
58
for any other cleaning, do NOT use
any cleaning agents that contain
acids or caustic or corrosive sub-
stances which would tend to corrode
the light metal components of the
machine if splashing occurs. The
stability and safety of the machine
could be compromised if such sub-
stances were used for cleaning and
are inadvertently splashed onto the
machine.
7. Put the inner blade flange (63) on
the saw spindle.
A
WARNING
59
Make sure the inner blade flange is
correctly fitted. Otherwise the saw
may jam or the saw blade may work
itself loose! The inner blade flange
(63) is correctly installed when the
bevelled collar (65) points to the
right and the groove for the safety
ring (64) points to the left.

8. Mount the new saw blade (62) and
pay attention to the direction. The
arrow on the saw blade must point
in the same direction as the arrow
on the blade cover (66).

A
DANGER
Do not use blunt, damaged or
warped saw blades.
A
WARNING
Never use grinding or cut-off
wheels instead of saw blades.
Use only saw blades approved
by the manufacturer. Do not use
super-speed steel (HSS) saw
blades.
Do not use loose-fitting reduc-
tion rings; the saw blade could
work itself loose.
Be sure that the saw blade is
properly fitted. Make sure the
blade it is firmly secured, does
not wobble, runs balanced and
cannot work itself loose.
9. Install the outer blade flange (61)
and be sure that the flat surfaces
are properly aligned and match.
10. Insert the arbor bolt (60), turn it
counterclockwise (left-hand thread)
and hand tighten with a metric Allen
wrench while keeping saw blade in
place with the saw blade lock (59).

Do not extend your wrench to
get more leverage.
Do not hit your wrench with a
hammer to tighten the arbor
bolt.
When tilting the sawhead assem-
bly, keep your hands out of the
track arm holder's tilting range!

sawhead assembly:
The retractable blade guard must
open without touching the saw
blade or any other parts.
When returning the sawhead
66
assembly to its starting position
the retractable blade guard must
return automatically so that the
entire saw blade is covered.
Check the saw blade lock – the
saw blade must turn freely.
