8. PREPARING THE CIRCULAR SAW 5. HEALTH AND SAFETY INFORMATION
- 8 -
– Kickback is the result of saw misuse and/or incorrect operating procedures or conditions and can
be avoided by taking proper precautions as given below.
● Maintain a firm grip with both hands on the saw and position your arms to resist kickback forces.
Position your body to either side of the blade, but not in line with the blade. Kickback could
cause the saw to jump backwards, but kickback forces can be controlled by the operator, if
proper precautions are taken.
● When blade is binding, or when interrupting a cut for any reason, release the trigger and hold
the saw motionless in the material until the blade comes to a complete stop. Never attempt to
remove the saw from the work or pull the saw backward while the blade is in motion or kickback
may occur. Investigate and take corrective actions to eliminate the cause of blade binding.
● When restarting a saw in the workpiece, centre the saw blade in the kerf and check that saw
teeth are not engaged into the material. If saw blade is binding, it may walk up or kickback from
the workpiece as the saw is restarted.
● Support large panels to minimise the risk of blade pinching and kickback. Large panels tend to
sag under their own weight. Supports must be placed under the panel on both sides, near the
line of cut and near the edge of the panel.
● Do not use dull or damaged blades. Unsharpened or improperly set blades produce narrow
kerf causing excessive friction, blade binding and kickback.
● Blade depth and bevel adjusting locking levers must be tight and secure before making cut. If
blade adjustment shifts while cutting, it may cause binding and kickback.
● Use extra caution when making a “plunge cut” into existing walls or other blind areas. The
protruding blade may cut objects that can cause kickback.
5.3 PENDULUM GUARDS
Check lower guard for proper closing before each use. Do not operate the saw if lower guard does
not move freely and close instantly. Never clamp or tie the lower guard into the open position. If the
saw is accidentally dropped, the lower guard may be bent. Raise the lower guard with the retracting
handle and make sure it moves freely and does not touch the blade or any other part, in all angles and
depths of cut.
Check the operation of the lower guard spring. If the guard and spring are not operating properly,
they must be serviced before use. The lower guard may operate sluggishly due to damaged parts,
gummy deposits, or a build up of debris.
Lower guard should be retracted manually only for special cuts such as “plunge cuts” and
“compound cuts”. Raise lower guard by retracting handle and as soon as the blade enters the
material, the lower guard must be released. For all other sawing, the lower guard should operate
automatically.
Always observe that the lower guard is covering the blade before placing saw down on bench
or floor. An unprotected, coasting blade will cause the saw to walk backwards, cutting whatever is in
its path. Be aware of the time it takes for the blade to stop after the switch is released.
5.4 ADDITIONAL SAFETY INSTRUCTIONS FOR CIRCULAR SAW BLADES
Safe Working Practice
Maximum speed. The maximum speed marked on the tool shall not be exceeded. Where stated, the
speed range shall be adhered to.
Circular saw blades
– Circular saw blades, the bodies of which are cracked, shall be scrapped (repairing is not
permitted).
– Composite (tipped) circular saw blades, where the tip dimension is reduced to less than 1mm, shall
be taken out of service.

Warning! Do not use abrasive wheels. Only use saw
blades recommended.
8.1 BLADE INSTALLATION
AND REPLACEMENT –
FIGS. 1 – 2
– Press and hold the spindle lock
button
(17)
. The spindle may
rotate slightly before the spindle
lock fully engages.
– Loosen the saw blade locking hex. bolt
(3)
anti-clockwise.
– Remove the hex. bolt
(3)
and the saw blade
locking flange
(4)
. If the rear flange is removed for
cleaning, ensure it is replaced in its correct
orientation.
– Slide the lower blade guard
(5)
back using tab
(2)
and hold.
– Ensure the specification of the replacement blade
conforms with the machine (i.e. outer diameter,
bore diameter, width, rpm and type, e.g.
woodcutting etc.). Before fitting the new blade
wipe a drop of oil on the inner and outer flanges
where the arbor locates.
– Insert the new blade.
Note: Install the blade with the direction of rotation
arrow matching the direction of rotation arrows on the
machine. The teeth face upward at the front of the
saw.
– Reassemble the locking flange
(3)
and secure the
locking hex. bolt
(3)
firmly.
Note: This saw is not designed to cut metal or masonry.
It is intended for cutting wood and analogous materials
only.
