SAFETY
The warnings, precautions, and instructions discussed in this instruction manual cannot cover all possible
conditions and situations that may occur. It must be understood by the operator that common sense and
caution are factors which cannot be built into this product, but must be supplied by the operator. Read

Gasoline is extremely ammable and poisonous. It should only be dispensed in well ventilated areas,
and with a cool engine. • Small gasoline engines produce high concentrations 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 fteen minutes. Five changes
of air in the same area will produce noxious fumes in less than 30 minutes. Gasoline or propane powered
equipment should not be used in enclosed or partially enclosed areas. Symptoms of CO poisoning include,
headache, nausea, weakness, dizziness, visual problems and loss of consciousness. If symptoms occur
- get into fresh air and seek medical attention immediately.
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.
Improper connection of the equipment-grounding conductor can result in a risk of electric shock. Check with
qualied electrician 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 t the outlet have a qualied electrician install the proper receptacle.
Switch motor OFF before disconnecting power.
DO NOT disconnect power by pulling cord. To disconnect, grasp the plug, not the cord.
Unplug power cord at the machine when not in use and before servicing.
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 ying debris or exposing them to harmful dust and noise.
For the operator’s safety and the safety of others, always keep all guards in place during operation.
NEVER let equipment run unattended.

ammable materials. Sparks from the cutting-action of this machine can ignite ammable materials or
vapors.
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
