g. Use the power tool, accessories and tool bits etc.,
in accordance with these instructions and in the
manner intended for the particular type of power
tool, taking into account the working conditions
and the work to be performed. Use of the power tool
for operations different from those intended could result
in a hazardous situation.
5. Service
a. Have your power tool serviced by a qualified repair
person using only identical replacement parts. This
will ensure that the safety of the power tool is maintained.
Safety instructions for all saws
Danger:
Keep hands away from cutting area and the blade.
N
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
N
cannot protect you from the blade below the workpiece.
Adjust the cutting depth to the thickness of the
N
workpiece. Less than a full tooth of the blade teeth
should be visible below the workpiece.
Never hold piece being cut in your hands or across
N
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.
Hold power tool by insulated gripping surfaces
N
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.
When ripping always use a rip fence or straight
N
edge guide. This improves the accuracy of cut and
reduces the chance of blade binding.
Always use blades with correct size and shape
N
(diamond versus round) of arbour holes. Blades that
do not match the mounting hardware of the saw will run
eccentrically, causing loss of control.
Never use damaged or incorrect blade washers or
N
bolt. The blade washers and bolt were specially designed
for your saw, for optimum performance and safety of
operation.
Further safety instructions for all saws
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;
6
- 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.
Maintain a firm grip with both hands on the saw
N
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
N
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
N
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
N
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
N
improperly set blades produce narrow kerf causing
excessive friction, blade binding and kickback.
Blade depth and bevel adjusting locking levers
N
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
N
existing walls or other blind areas. The protruding
blade may cut objects that can cause kickback.
