IMPORTANT SAFETY INFORMATION

WARNING! Read all instructions.

Failure to follow all instructions listed below may result in re, serious injury and/or DEATH.

The warnings and precautions discussed in this 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.

SAVE THESE INSTRUCTIONS

Set Up Precautions

1. Gasoline fuel and fumes are ammable, and
potentially explosive. Use proper fuel storage
and handling procedures. Do not store fuel

or other ammable materials nearby.

2. Have multiple ABC class re extinguishers nearby.

3. Operation of this equipment may create sparks that
can start res around dry vegetation.
A spark arrestor may be required.

The operator should contact local re

agencies for laws or regulations relating

to re prevention requirements.

4. Set up and use only on a at, level,
well-ventilated surface.

5. Wear ANSI-approved safety goggles, heavy-duty
work gloves, and dust mask/respirator during set up.

6. Use only lubricants and fuel recommended
in the engine manual or in the

Specications chart of this manual.

Engine Precautions

Follow engine precautions and instructions in
the included engine instruction manual.

Operating Precautions

1. CARBON MONOXIDE HAZARD
Using an engine indoors CAN KILL
YOU IN MINUTES.

Engine exhaust contains carbon
monoxide. This is a poison you cannot
see or smell.

NEVER use inside a home or garage,
EVEN IF doors and windows are open.

Only use OUTSIDE and far away from windows,
doors, and vents.

2. Keep children away from the equipment,
especially while it is operating.

5. Wear heavy-duty work gloves
when handling the blade.

6. People with pacemakers should consult their
physician(s) before use. Electromagnetic

elds in close proximity to a heart pacemaker

could cause pacemaker interference or
pacemaker failure. Caution is necessary when
near the engine's magneto or recoil starter.

7. Use only accessories that are recommended
by Harbor Freight Tools for your model.
Accessories that may be suitable for one
piece of equipment may become hazardous
when used on another piece of equipment.
