saw spindle against the inner clamp washer
sure that the blade will rotate in the proper direction (the
direction of the rotation arrow on the saw blade and the
teeth must point in the same direction as the direction of
rotation arrow on the saw). Do not assume that the printing
on the blade will always be facing you when properly
installed. When retracting the lower blade guard to install
the blade, check the condition and operation of the lower
blade guard to assure that it is working properly. Make sure
it moves freely and does not touch the blade or any other
part, in all angles and depths of cut.
3. Place the outer clamp washer

Always use blades that are the correct size (diameter)
with the proper size and shape centre hole for mounting
on the saw spindle. Always assure that the maximum
recommended speed (rpm) on the saw blade meets or

Lower Blade Guard


WARNING: Under certain conditions of use, metal chips
may become imbedded in the surfaces of the lower guard,
causing the lower guard to rub against the upper guard.
Check the operation of the lower guard before each use
and remove any imbedded chips.

WARNING: The lower blade guard is a safety feature
which reduces the risk of serious personal injury.
Never use the saw if the lower guard is missing,
damaged, misassembled or not working properly.
Do not rely on the lower blade guard to protect
you under all circumstances. Your safety depends
on following all warnings and precautions as well
as proper operation of the saw. Check lower guard
for proper closing before each use as outlined
in Additional safety Rules for Circular saws. If
the lower blade guard is missing or not working
properly, have the saw serviced before using.
To assure product safety and reliability, repair,
maintenance and adjustment should be performed
by an authorised service centre or other qualified
service organization, always using identical
replacement parts.
Blades

WARNING: To minimise the risk of eye injury, always
use eye protection. Carbide is a hard but brittle material.
Foreign objects in the workpiece such as wire or nails
can cause tips to crack or break. Only operate saw when
proper saw blade guard is in place. Mount blade securely
in proper rotation before using, and always use a clean,
sharp blade.

Kickback
Kickback is a sudden reaction to a pinched, bound or misaligned
saw blade, causing an uncontrolled saw to lift up and out of the
workpiece toward the operator. When the blade is pinched or
bound tightly by the kerf closing down, the blade stalls and the
motor reaction drives the unit rapidly back toward the operator.
