8. Never use damaged or incorrect blade wash-
ers 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, 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 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.
9. 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.
10. 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
11.
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.
12. 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.
To avoid kickback, do support
board or panel near the cut.
Do not support board or
panel away from the cut.
13. Do not use dull or damaged blades. Unsharpened
or improperly set blades produce narrow kerf causing
excessive friction, blade binding and kickback.
14. 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.
15. Use extra caution when sawing into existing
walls or other blind areas. The protruding blade
may cut objects that can cause kickback.
16. ALWAYS hold the tool firmly with both hands.
NEVER place your hand, leg or any part of your
body under the tool base or behind the saw,
especially when making cross-cuts. If kickback
occurs, the saw could easily jump backwards over
your hand, leading to serious personal injury.
17. Never force the saw. Push the saw forward at a
speed so that the blade cuts without slowing.
Forcing the saw can cause uneven cuts, loss of
accuracy, and possible kickback.
Guard function
18. Check guard for proper closing before each
use. Do not operate the saw if guard does not
move freely and enclose the blade instantly.
Never clamp or tie the guard so that the blade
is exposed. If saw is accidentally dropped, guard
may be bent. Check to make sure that guard
moves freely and does not touch the blade or any
other part, in all angles and depths of cut.
19. Check the operation and condition of the guard
return spring. If the guard and the spring are not
operating properly, they must be serviced before
use. Guard may operate sluggishly due to damaged
parts, gummy deposits, or a build-up of debris.
20. Assure that the base plate of the saw will not
shift while performing the "plunge cut" when the
blade bevel setting is not at 90°. Blade shifting
sideways will cause binding and likely kick back.
