3. Adjust the cutting depth to the thickness of the
workpiece.
Less than a full tooth of the blade teeth should be
visible below the workpiece.
4. NEVER hold piece being cut in your hands or
across your leg. Secure the workpiece to a stable
platform.
It is important to support the work properly to
minimize body exposure, blade binding, or loss of
control.
5. Hold power tool by insulated gripping surfaces
when performing an operation where the cutting
tool may contact hidden wiring or its own cord.
Contact with a “live” wire will also make exposed
metal parts of the power tool “live” and shock the
operator.
6. When ripping always use a rip fence or straight
edge guide.
This improves the accuracy of cut and reduces the
chance of blade binding.
7. Always use blades with correct size and shape
(diamond versus round) arbour holes.
Blades that do not match the mounting hardware
of the saw will run eccentrically, causing loss of
control.
8. 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.
9. Causes and Operator Prevention of 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 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:
10. 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.
11. 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.
12. When restarting a saw in the workpiece, center
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.
13. Support large panels to minimize 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 as shown in Fig. 1.
To minimize the risk of blade pinching and
kickback. When cutting operation requires the
resting of the saw on the work piece, the saw shall
be rested on the larger portion and the smaller
piece cut off.
To avoid kickback, do support board
or panel near the cut.
Fig. 1
Don't support board or panel away
from the cut.

14. Do not use dull or damaged blades.
Unsharpened or improperly set blades produce
narrow kerf causing excessive friction, blade
binding and KICKBACK.
15. 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.
