Operating Precautions


Use Good Judgement

Always make sure the cutter attachment is properly installed and firmly tightened before operation.

Never use a cracked or warped cutter or cutter bar: replace it with a serviceable one and make sure it fits properly.

Before starting the engine, make sure the cutter is not contacting anything.

Always stop the engine immediately and check for damage if you strike a foreign object or if the unit becomes tangled. Do not operate with broken or damaged equipment.

When cutting a branch that is under tension, be alert for spring-back so that you will not be struck by the moving branch.

Stop the unit immediately if it suddenly begins to vibrate or shake. Inspect for broken, missing or improperly installed parts or attachments.

Do not operate the articulated hedge trimmer with the muffler removed.

Make sure there is always good ventilation when operating the articulated hedge trimmer. Fumes from engine exhaust can cause serious injury or death. Never run the engine indoors!

Make sure there are no missing or loose fasteners, and that the stop switch and throttle controls are working properly.

If a cutter should bind fast in a cut, shut off the engine immediately. Push the branch or tree to ease the bind and free the cutter.

Make sure the cutters are correctly adjusted before operating the articulated hedge trimmer (see page 24 for cutter adjustment procedures). Never attempt cutter adjustment with the engine running!


Minimize the Risk of Fire

NEVER smoke or light fires near the unit.

ALWAYS stop the engine and allow it to cool before refueling. Avoid overfilling and wipe off any fuel that may

have spilled.

ALWAYS move the unit to a place well away from a fuel storage area or other readily flammable materials before starting the engine.

ALWAYS inspect the unit for fuel leaks before each use. During each refill, check that no fuel leaks from around the fuel cap and/or fuel tank. If fuel leaks are evident, stop using the unit immediately. Fuel leaks must be repaired before using the unit.

NEVER place flammable material close to the engine muffler.

NEVER run the engine without the spark arrester screen in place.
