For Your Own Safety, Read Instruction
Manual Before Operating this Machine
The purpose of safety symbols is to attract your attention to possible hazardous conditions.
This manual uses a series of symbols and signal words intended to convey the level of impor-
tance of the safety messages. The progression of symbols is described below. Remember that
safety messages by themselves do not eliminate danger and are not a substitute for proper
accident prevention measures.

No list of safety guidelines can be complete.
Every shop environment is different. Always
consider safety first, as it applies to your
individual working conditions. Use this and
other machinery with caution and respect.
Failure to do so could result in serious per-
sonal injury, damage to equipment, or poor
work results.
Like all machinery there is potential danger
when operating this machine. Accidents are
frequently caused by lack of familiarity or
failure to pay attention. Use this machine
with respect and caution to decrease the
risk of operator injury. If normal safety pre-
cautions are overlooked or ignored, serious
personal injury may occur.

these products.
Many cleaning solvents
are toxic if concentrat-

NOTICE
Avoid chlorine-based solvents, such as
acetone or brake parts cleaner, that may
damage painted surfaces. Test all cleaners
in an inconspicuous area before using to
make sure they will not damage paint.
