4. Thread the blade clamping screw (f) into the
saw spindle by hand. (Screw has left-hand
threads and must be turned counterclockwise
to tighten. Refer to arrow in Figure 7A.)
5. Depress the spindle lock button (d) while turning
the saw spindle with the hex key (l, fig. 1) until
the spindle lock engages and the blade stops
rotating.
6. Tighten the blade clamping screw firmly with the
hex key.
NOTICE: Never engage the spindle
lock while saw is running, or engage
in an effort to stop the tool. Never turn
the saw on while the spindle lock is
engaged. Serious damage to your saw
will result.
TO REPLACE THE BLADE
1. To loosen the blade clamping screw (f), depress
the spindle lock button (d) and turn the saw
spindle (s) with the hex key (l) until the spindle
lock engages and the blade stops rotating.
With the spindle lock engaged, turn the blade
clamping screw clockwise with the hex key.
(Screw has left-hand threads and must be
turned clockwise to loosen. Refer to arrow in
Figure 7B.)
2. Remove the blade clamping screw (f) and outer
clamp washer (r) only. Remove old blade.
3. Clean any metal chips/shavings that may have
accumulated in the guard or clamp washer area
and check the condition and operation of the
lower blade guard as previously outlined. Do not
lubricate this area.
4. Select the proper blade for the application
(see Blades ). 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 exceeds the speed (rpm) of the saw.
5. Follow steps 2 through 6 under To Install the
Blade , making sure that the blade will rotate in
the proper direction.
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. If the blade becomes twisted or
misaligned in the cut, the teeth at the back edge of
the blade can dig into the top surface of the material
causing the blade to climb out of the kerf and jump
back toward the operator.
