USE PROPER EXTENSION CORD. 9.
Make sure your extension cord is
in good condition. When using an
extension cord, be sure to use one
heavy enough to carry the current
your product will draw. An undersized
cord will cause a drop in line voltage
resulting in loss of power and overheating. Table A shows the correct
size to use depending on cord length
and nameplate ampere rating. If in
doubt, use the next heavier gauge.
The smaller the gauge number, the
heavier the cord.

wear loose clothing, gloves, neckties, rings, bracelets, or other jewelry
which may get caught in moving

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

harm. Some examples of these
chemicals are:
• Lead from lead-based paints
• Crystalline silica from bricks and ce-
ment or other masonry products
• Arsenic and chromium from chemically treated lumber
Your risk from these exposures varies, depending on how often you do
this type of work. To reduce your
exposure to these chemicals: work in
a well ventilated area, and work with

Vibration Safety
This tool vibrates during use. Repeated or long-term exposure to
vibration may cause temporary or
permanent physical injury, particularly
to the hands, arms and shoulders. To
reduce the risk of vibration-related
injury:
Do not smoke during use. Nico-2.
tine reduces the blood supply to the
hands and ngers, increasing the risk
of vibration-related injury.
Wear suitable gloves to reduce the 3.
vibration effects on the user.
Use tools with the lowest vibration 4.
when there is a choice between different processes.
Include vibration-free periods each 5.
day of work.
Grip tool as lightly as possible (while 6.
still keeping safe control of it). Let
the tool do the work.
To reduce vibration, maintain the tool 7.
as explained in this manual. If any
abnormal vibration occurs, stop use
immediately.
