GENERAL SAFETY RULES
POWER TOOL USE AND CARE
Do not force the power tool. Use the correct power
■
tool for your application. The correct power tool will
do the job better and safer at the rate for which it was
designed.
Do not use the power tool if the switch does not
■
turn it on and off. Any power tool that can not be
controlled with the switch is dangerous and must be
repaired.
Disconnect the plug from the power source
■
before making any adjustments, changing
accessories or storing power tools. Such
preventive safety measures reduce the risk of starting
the power tool accidentally.
Store idle power tools out of the reach of children
■
and do not allow persons unfamiliar with the
power tool or these instructions to operate the
power tool. Power tools are dangerous in the hands
of untrained users.
Maintain power tools. Check for misalignment or
■
binding of moving parts, breakage of parts and any
other condition that may affect the power tools
operation. If damaged, have the power tool repaired
before use. Many accidents are caused by poorly
maintained power tools.
Keep cutting tools sharp and clean. Properly
■
maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control.
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 intended could result
in a hazardous situation.
SERVICE
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.
Check damaged parts. Before further use of the
■
tool, a guard or other part that is damaged should be
carefully checked to determine that it will operate
properly and perform its intended function. Check for
alignment of moving parts, free running of moving
parts, breakage of parts, mounting and any other part
that is damaged should be properly repaired or
replaced by an authorized service centre unless
otherwise indicated in this instruction manual.
Have defective switches replaced by an authorized
service centre. Do not use the tool if the switch does
not turn it on and off.
PARTICULAR REQUIREMENTS FOR CIRCULAR
SAWS
Not to use any abrasive wheels
Ensure that the riving knife is adjusted so that the
distance between the riving knife and the rim of the
blade is not more than 5mm, and the rim of the blade
does not extend more than 5mm beymond the lowest
edge of the riving knife.
Safety instructions for all saws
DANGER:
Keep hands away from cutting area and 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.
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.
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.
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.
When ripping always use a rip fence or straight
■
edge guide. This improves the accuracy of cut and
reduces the chance of blade binding.
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
eccentrically, 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.
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;
