GASOLINE/PROPANE POWERED EQUIPMENT
• Engine exhaust from this product contains
chemicals known to the State of California to
cause cancer, birth defects or other reproductive harm.
• Gasoline is extremely fl ammable and poisonous.
It should only be dispensed in well ventilated areas,
and with a cool engine.
• Small gasoline engines produce high concentra-
tions of carbon monoxide (CO) example: a 5 HP 4 cycle
engine operation in an enclosed 100,000 cu. ft. area with
only one change of air per hour is capable of providing
deadly concentrations of CO in less than fi fteen minutes.
Five changes of air in the same area will produce noxious
fumes in less than 30 minutes. Gasoline or propane pow ered equipment should not be used in enclosed or partially
enclosed areas. Symptoms of CO poisoning include, head ache, nausea, weakness, dizziness, visual problems and
loss of consciousness. If symptoms occur - get into fresh
air and seek medical attention immediately.
ELECTRICAL POWERED EQUIPMENT
Extreme care must be taken when operating electric
models with water present: Ensure power cord is properly grounded, is attached to a Ground-Fault-Interrupter
(GFI) outlet, and is undamaged.
• Check all electrical cables - be sure connections are tight and
cable is continuous and in good condition. Be sure cable is
correctly rated for both the operating current and voltage of
this equipment.
• Improper connection of the equipment-grounding conductor can
result in a risk of electric shock. Check with qualifi ed electri-
cian or service person if there is any doubt as to whether the
outlet is properly grounded. Adhere to all local codes and
ordinances.
• NOTE: In the event of a malfunction or breakdown, grounding
provides a path of least resistance for the electric current to
dissipate. The motor is equipped with a grounded plug and
must be connected to an outlet that is properly installed and
properly grounded. DO NOT modify the plug provided on the
motor. If the plug does not fi t the outlet have a qualifi ed electri-
cian install the proper receptacle.
• Switch motor OFF before disconnecting power.
• Do not disconnect power by pulling cord. T o disconnect, grasp
the plug, not the cord.
• Unplug power cord at the machine when not in use and before
servicing.
GENERAL INSTRUCTIONS
• Equipment should only be operated by trained personnel in
good physical condition and mental health (not fatigued). The
operator and maintenance personnel must be physically able
to handle the bulk weight and power of this equipment.
• This is a one person tool. Maintain a safe operating distance
to other personnel. It is the operators’ responsibility to keep
other people (workers, pedestrians, bystanders, etc.) away
during operation. Block off the work area in all directions with
roping, safety netting, etc. for a safe distance. Failure to do so
may result in others being injured by fl ying debris or exposing
them to harmful dust and noise.
• This equipment is intended for commercial use only.
• For the operator’s safety and the safety of others, always keep
all guards in place during operation.
• Never let equipment run unattended.
• Personal Protection Equipment and proper safety attire must
be worn when operating this machinery. The operator must
wear approved safety equipment appropriate for the job such
as hard hat and safety shoes when conditions require. Hearing protection MUST be used (operational noise levels of this
equipment may exceed 90db). Eye protection MUST be worn
at all times.
Keep body parts and loose clothing away from moving
parts. Failure to do so could result in dismemberment
or death.
• Do not modify the machine.
• Stop motor/engine when adjusting or servicing this equipment.
Maintain a safe operating distance from fl ammable
materials. Sparks from the cutting-action of this machine
can ignite fl ammable materials or vapors.
DUST WARNING
Some dust created by power sanding, sawing,
grinding, drilling, and other construction activities contains chemicals known to cause cancer,
birth defects, or other reproductive harm. Some
examples of these chemicals are:
• Lead from lead-based paints, and
• Crystalline silica from bricks and concrete and other
masonry products.
Your risk of exposure to these chemicals varies depending
on how often you do this type of work. To reduce your risk:
work in a well ventilated area, use a dust control system, such
as an industrial-style vacuum, and wear approved personal
safety equipment, such as a dust/particle respirator designed
to fi lter out microscopic particles.
