GENERAL SAFETY RULES
WARNING: Read all safety warnings and instructions prior to use.
Failure to follow all warnings and instructions may result in electric shock, fire, and/or
serious injury.
Save all warnings and instructions for future reference.
The term “floor machine” in the warnings refers to your corded floor machine.
1. WORK AREA SAFETY
a. Keep work area clean and well lit during operation.
b. Do not operate floor machine in explosive atmospheres, such as in the presence of
flammable liquids, gases, or dust.
c. Keep children and bystanders away while operating a floor machine to avoid potential
injury.
2. ELECTRICAL SAFETY
a. Floor machine plugs must match the outlet. Never modify the plug in any way. Do not use
any adapter plugs with grounded floor machines. Unmodified plugs and matching outlets
will reduce risk of electric shock.
b. Avoid body contact with grounded surfaces, such as pipes, radiators, ranges, and
refrigerators.
c. Do not expose floor machines to rain or wet conditions. Water entering the floor machine
will increase the risk of electric shock.
d. Do not abuse the cord. Never use the cord for carrying, pulling, or unplugging the floor
machine. Keep cord away from heat, oil, sharp edges, or moving parts. Damaged or
entangled cords increase the risk of electric shock. Never operate this unit with a damaged
cord.
e. When operating a floor machine outdoors, use an extension cord suitable for outdoor use.
Use of a cord suitable for outdoor use reduces the risk of electric shock.
f. If operating a floor machine in a damp location is unavoidable, use a residual current
device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.
3. PERSONAL SAFETY
a. Stay alert, watch what you are doing, and use common sense when operating a floor
machine. Do not use a floor machine while you are tired or under the influence of drugs,
alcohol, or medication. Lack of attention while operating a floor machine may result in
serious personal injury.

INSTRUCTION MANUAL  3
b. Always use appropriate personal protective equipment. Always wear eye protection.
Protective equipment such as a dust mask, non-skid safety shoes, hard hat, or hearing
protection used for appropriate conditions can reduce personal injuries.
c. Ensure the switch is in the o-position before connecting to power source, picking up, or
carrying the tool. Carrying floor machines with your finger on the power switch may cause
accidents.
d. Make sure that you are balanced and stabile before operation. Keep proper footing
and balance at all times. This enables better control of the floor machine in unexpected
situations.
e. Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing, and gloves
away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts.
f. Always stay alert during machine operation. A lack of awareness while in use can cause
severe injury.
4. FLOOR MACHINE USE AND CARE
a. Use the correct floor machine for your application. The correct floor machine will do the job
better and safer at the rate for which it was designed.
b. Do not use the floor machine if the switch does not turn it on and o. Any floor machine
that cannot be controlled with the switch is dangerous and must be repaired.
c. Disconnect your floor machine from the power source before making any adjustments,
changing accessories, or storing the unit. Such preventive safety measures reduce the risk
of starting the floor machine accidentally.
d. Store idle floor machines out of the reach of children and do not allow persons unfamiliar
with the floor machine or these instructions to operate the floor machine.
e. Maintain floor machines and accessories. Check for misalignment or binding of moving
parts, breakage of parts, and any other condition that may aect the floor machine’s
operation. If damaged, have the floor machine repaired before use. Accidents may be
caused by poorly maintained floor machines.
f. Only use the floor machine and accessories in accordance with these instructions. Always
take into account the working conditions and the work to be performed. Use of the floor
machine for unintended functions could result in hazardous situations.
g. Keep handles and grasping surfaces dry, clean, and free from oil and grease. Slippery
handles and grasping surfaces do not allow for safe handling and control of the tool in
unexpected situations.
