! WARNING! WARNING

! DANGER! DANGER

! CAUTION! CAUTION

• Be prepared in case of emergency:

Keep a fire extinguisher nearby

Keep a first aid kit nearby

Keep emergency contact numbers handy

• Replace any missing or damaged safety labels on shop equipment.

• Replace any missing or damaged safety labels on equipment being serviced.

• Remember that some hazards have a cumulative effect. A single exposure may

cause little or no harm, but continual or repeated exposure may cause very serious

harm.

• Clean spills and fix obviously dangerous conditions as soon as they are noticed.

• Lift and support heavy objects safely and securely.

• Be aware of your surroundings and potential hazards that are inherent to all power

equipment. All the labels in the world cannot protect a technician from an instant of

carelessness.

! CAUTION! CAUTION

• Grooming and attire:

Do not wear loose fitting clothing that may become entangled in equipment.

Long hair should be secured to prevent entanglement in equipment.

Jewelry is best removed.

• Protective gear: includes, but is not limited to

Clear eye protection ................................ while working around any machinery

Protective gloves..................................... where necessary

Armored footwear.................................... when working around any machinery

Hearing protection................................... in noisy environments

Chemically resistant gloves..................... when working with chemicals or solvents

Respirator................................................ when working with chemical or solvents

Appropriate tinted eye protection............. when cutting or welding

Flame resistant headgear, jacket, chaps. when cutting or welding

! WARNING! WARNING

• Exhaust fumes from running engines contain carbon monoxide (CO). Carbon

monoxide is a colorless odorless gas that is fatal if inhaled in sufficient quantity.

Only run engines in well ventilated areas. If running engines indoors, use an

exhaust evacuation system with adequate make-up air ventilated into the shop.

Fasteners

• The fasteners used on the equipment described in this manual, and the engine that powers it are a combi-

nation of metric and fractional inch. For this reason, wrench sizes are frequently identified in the text, and

measurements are given in U.S. and metric scales.

• If a fastener has a locking feature that has worn, replace the fastener or apply a small amount of releas-

able thread locking compound such as Loctite® 242 (blue).

• Some fasteners, like cotter pins, are single-use items that are not to be reused. Other fasteners, such as:

lock washers, retaining rings, and internal cotter pins (hairpin clips), may be reused if they do not show

signs of wear or damage. This manual leaves that decision to the judgment of the technician.

Assembly instructions

•Torque specifications may be noted in the part of the text that covers assembly. They may be summa-

rized in tables along with special instructions regarding locking or lubrication. Whichever method is more

appropriate will be used. In many cases, both will be used so that the manual is handy as a quick-refer-

ence guide as well as a step-by-step procedure guide that does not require the user to hunt for informa-

tion.

•Lubricant quantity and specification may be noted in the part of the text that covers maintenance, and

again in the section that covers assembly. They may also be summarized in tables along with special

instructions. Whichever method is more appropriate will be used. In many cases, the information will be

found in several places in the manual so that the manual is handy as a quick-reference guide as well as a

step-by-step procedure guide that does not require the user to hunt for information.

• The level of assembly instructions provided will be determined by the complexity of reassembly, and by

the potential for damage or unsafe conditions to arise from mistakes made in assembly.

• Some instructions may refer to other parts of the manual for subsidiary procedures. This avoids repeating

the same procedure two or three times in the manual.

The 22” wheeled string trimmer was intended for clear-

ing heavy growth from unimproved land. This model has a

engine brake feature. When the engagement control lever
