IMPORTANT: 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

against the inner clamp
washer
30
, making 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 lower bladeguard).
IMPORTANT: Always ensure the diamond-shaped arbor
centre of the blade aligns with the raised diamond-shaped
arbor centre on the outer clampwasher.
NOTE: Do not assume that the printing on the saw blade will
always be facing you when properlyinstalled.

27
on saw spindle
29
with the
large flat surface against the blade and the wording on the

, retract the
lower blade guard. Remove used blade and properlydiscard.
5. Install new blade as previouslydescribed.
6. Clean any sawdust that may have accumulated in the guard
or clamp washer area. Check the condition and operation
of the lower blade guard as previously outlined. Do not
lubricate thisarea.
7. Select the proper blade for the application (refer to Blades).
Always use blades that are the correct size (190mm
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 exceeds the speed (rpm) of thesaw.
Lower Blade Guard

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 Safety
Instructions for All 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 organisation, 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.
Do not use abrasive wheels or blades. A dull blade will cause
slow, inefficient cutting resulting in overload to the saw motor,
excessive splintering and could increase the possibility of
kickback. Please refer to the following table to determine the
correct size replacement blade for your modelsaw.
