- Always use blades with correct size and shape
(diamond versus round) of arbour holes. Blades
that do not match the mounting hardware of the saw
will run off-centre, causing loss of control.
- Never use damaged or incorrect blade washers
or bolt. The blade washers and bolt were specially
designed for your saw, for optimum performance
and safety of operation.
Kickback causes and related warnings
- kickback is a sudden reaction to a pinched, jammed
or misaligned saw blade, causing anuncontrolled
saw to lift up and out of the workpiece toward the
operator;
- When the blade is pinched or jammed 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 wood causing the blade
to climb out of the kerf and jump back toward the
operator.
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 so that the saw teeth
are not engaged into the material. If a saw blade
binds, 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 the cut.
If blade adjustment shifts while cutting, it may cause
binding and kickback.
- Use extra caution when sawing into existing
walls or other blind areas. The protruding blade
may cut objects that can cause kickback.
Lower guard function
- Prior to every use, check whether the lower saw
guard is closing properly. Do not use the saw if
the lower saw guard is not freely movable and
does not close immediately. Never clamp or tie
down the lower saw guard in an open position.
If the saw is dropped inadvertently, the lower saw
guard can get bent. Open the saw guard with the
pre-feed lever and ensure that it moves freely and
touches neither saw blade nor other parts
irrespective of the cutting angle and depth.
- Check the operation of the lower guard spring.
If the guard and the spring are not operating
properly, they must be serviced before use.
Lower guard may operate sluggishly due to
damaged parts, gummy deposits, or a build-up of
debris.
- Only manually open the lower saw guard for
special cuts, such as "plunge and angle cuts".
Open the lower saw guard using the pre-feed
lever and release the lever as soon as the saw
blade has penetrated the workpiece. During all
other sawing work, the lower saw guard is to
operate automatically.
- Always observe that the lower guard is covering
the blade before placing the 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 switch is released.
