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 scrubber” in the warnings refers to your battery-operated floor scrubber.
1. WORK AREA SAFETY
a. Keep work area clean and well lit during operation.
b. Do not operate floor scrubber in explosive atmospheres, such as in the presence of flammable liquids,
gases, or dust.
c. Keep children and bystanders away while operating a floor scrubber to avoid potential injury.
2. ELECTRICAL SAFETY
a. Avoid body contact with grounded surfaces, such as pipes, radiators, ranges, and refrigerators.
b. Do not expose floor scrubbers to rain or wet conditions. Water entering the floor scrubber will increase the risk of
electric shock.
c. If operating a floor scrubber 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 scrubber. Do not use a floor
scrubber while you are tired or under the influence of drugs, alcohol, or medication.
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 scrubbers with your finger on the power switch may cause accidents.
d. Make sure that you are balanced and stable before operation. Keep proper footing and balance at all times.
This enables better control of the floor scrubber 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 SCRUBBER USE AND CARE
a. Use the correct floor scrubber for your application. The correct floor scrubber will do the job better and safer at
the rate for which it was designed.
b. Do not use the floor scrubber if the switch does not turn it on and o. Any floor scrubber that cannot be
controlled with the switch is dangerous and must be repaired.
c. Disconnect your floor scrubber 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 scrubber accidentally.
d. Store idle floor scrubbers out of the reach of children and do not allow persons unfamiliar with the floor scrubber
or these instructions to operate the floor scrubber.
e. Maintain floor scrubbers and accessories. Check for misalignment or binding of moving parts, breakage of parts,
and any other condition that may aect the floor scrubber’s operation. If damaged, have the floor scrubber
repaired before use. Accidents may be caused by poorly maintained floor scrubbers.
f. Only use the floor scrubber and accessories in accordance with these instructions. Always take into account the
working conditions and the work to be performed. Use of the floor scrubber 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.
5. SERVICE
