IMPORTANT SAFETY
INSTRUCTIONS
When using the tool, please take the basic safety
precautions as described below to prevent possible
injury.
GENERAL: TOOLS
Warning
To Operators
●Wear proper clothing for the type of work being
done.
No loose clothing nor adornments when at work: you
will be pulled into the tool if you’re unlucky. Wear
nonskid footwear. If you have long hair, wear a
safety hat that can cover up your hair completely.
●Always wear safety glasses.
Remember, regular glasses are no safety glasses.
The lenses are only shock resistant, which will not
give you sufficient eye protection you may need in
your working environment.
●Wear respiratory protective equipment (PPE).
Wear respiratory protective equipment (PPE) when
working in an environment where dust particles are
generated in operation.
●Avoid working posture that is too stressful.
Secure good footing, work in a well-balanced
posture.
●Do not operate the machine if you are too tired.
●Never touch any moving member on the tip of
machine when running.
About Work Area
●Keep the work area clean.
Cluttered work areas (e.g. workbench) invite
accidents.
●Carefully select the work area.
Do not expose tool to rain. Do not use tool in a wet
or soaked area.
See that the work area is adequately illuminated.
●Never work near inflammable liquid or in a
potentially explosive atmosphere.
●Keep children off the work area.
Keep children and unauthorized persons off the
work area.
Before Operation
●Inspect tool before use.
Before using, check that screws are securely
tightened, that a protective cover and other parts
are free from damage, and that the tool runs as it
should.
Check that moving members are properly adjusted
for positioning and tightened, that parts are free from
damage and properly mounted, and that all other
parts are in good condition for normal operation.
Should you find any damage to the protective cover
or other part, replace it in accordance with the
Operation Manual. If there are no instructions in the
Manual, please contact sales agent through which
you have purchased your tool or an authorized
dealer near you for repair.
Likewise, if a switch failure occurs, contact sales
agent through which you have purchased your tool
or an authorized dealer near you for repair.
Do not use the tool -- if it does not start or stop with

●Always remove spanner, wrench, etc., once
adjustment is made with them.
●Use a tool appropriate for the application.
Avoid heavy-duty application that is beyond the
capacity of tool.
Do not use tool for other purposes than is geared to.
●Do not abuse tool.
Use tool in accordance with the specifications: you’ll
get the most out of it while ensuring safely.

damage to an accessory or part, please contact
sales agent through which you have purchased your
tool or an authorized dealer near you for repair.
●Check parts for damage.
When you have found damage to accessory or other
part, carefully check the damaged part to determine
the extent of influence it has upon the functions of
the power tool – that is, determine whether it can
still perform its normal functions. Check to see that
the linkage of the moving members is OK, that all
