1. Retract the lower blade guard
retracting lever 6 and place the blade on the saw spindle
against the inner clamp washer, 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). 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.

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 blade 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 blade guard for
proper closing before each use as outlined in Further
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 authorized service center or other
qualified service organization, always using identical
replacement parts.
Blades

WARNING: To minimize 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.

WARNING: Do not cut metal, plastic, concrete, masonry
or fiber cement materials with this saw.
Do not use abrasive wheels or blades. A dull blade will
cause slow inefficient cutting, overload on the saw motor,
excessive splintering, and could increase the possibility of
kickback. Please refer to the table below to determine the
correct size replacement blade for your model saw.
