the blade. Keep your second hand on auxiliary
handle, or motor housing. If both hands are
holding the saw, they cannot be cut by the blade.
Do not reach underneath the workpiece. The
guard cannot protect you from the blade below
the workpiece.
2.
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.
3.
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.
4.
Hold the power tool by insulated gripping
surfaces only, when performing an operation
where the cutting tool may contact hidden wiring.
Contact with a "live" wire will also make exposed
metal parts of the power tool "live" and could give
the operator an electric shock.
5.
When ripping, always use a rip fence or straight
edge guide. This improves the accuracy of cut
and reduces the chance of blade binding.
6.
Always use blades with correct size and shape
(diamond versus round) of ar bour holes. Blades
that do not match the mounting hardware of the
saw will run eccentrically, causing loss of control.
7.
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, 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.
8.
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.
9.
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.
10.
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.
11.
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.
12.
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.
13.
Use extra caution when sawing into existing walls
or other blind areas. The protruding blade may
cut objects that can cause kickback.
14.
ALWAYS hold the tool firmly with both hands.
NEVER place your hand or fingers behind the saw.
If kickback occurs, the saw could easily jump
backwards over your hand, leading to serious
personal injury.
15.
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. Lower guard
function
16.
Check lower guard for proper closing before each
use. Do not operate the saw if lower guard does
not move free lyand close instantly. Never clamp
or tie the lower guard into the open position. If
saw is accidentally dropped, 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.
17.
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.
18.
Lower guard may be retracted manually only for
special cuts such as "plunge cuts" and
"compound cuts". Raise lower guard by retracting
handle and as soon as blade enters the material,
the lower guard must be released. For all other
sawing,
the
automatically.
19.
Always observe that the lower guard is covering
the blade before placing saw down on bench or
floor. Anun protected, coasting blade will cause
