SAFETY RULES
Personal Safety
Any person working on or around a machine must
be aware of all known safety hazards. Personal
safety and the continued safe operation of the
machine should be your top priority.
Read each procedure thoroughly. This
manual and the decals on the machine use
signal words to identify the following:
Safety alert symbol—used to alert
personnel to potential personal
injury hazards. Obey all safety
messages that follow this symbol
to avoid possible injury or death.
Used to indicate the presence of
an imminently hazardous situation
which, if not avoided, will result in
death or serious injury.
Used to indicate the presence of a
potentially hazardous situation
which, if not avoided, could result
in death or serious injury.
Used to indicate the presence of a
potentially hazardous situation
which, if not avoided, may result in
minor or moderate injury.
Used to indicate the presence of a
potentially hazardous situation
which, if not avoided, may result in
property damage.
Be sure to wear protective eye wear and
other protective clothing if the situation
warrants it.
Be aware of potential crushing hazards
such as moving parts, free swinging or
unsecured components when lifting or
placing loads. Always wear approved steel-toed
shoes.
Workplace Safety
Be sure to keep sparks, flames and
lighted tobacco away from flammable and
combustible materials like battery gases
and engine fuels. Always have an approved fire
extinguisher within easy reach.
Be sure that all tools and working areas
are properly maintained and ready for
use. Keep work surfaces clean and free
of debris that could get into machine components
and cause damage.
Be sure any forklift, overhead crane or
other lifting or supporting device is fully
capable of supporting and stabilizing the
weight to be lifted. Use only chains or straps that
are in good condition and of ample capacity.
Be sure that fasteners intended for one
time use (i.e., cotter pins and self-locking
nuts) are not reused. These components
may fail if they are used a second time.
Be sure to properly dispose of old oil or
other fluids. Use an approved container.
Please be environmentally safe.
Be sure that your workshop or work area
is properly ventilated and well lit.
