OPERATION

n Do not cut from a ladder; this is extremely dangerous. Leave this operation for professionals.

n Do not make the flush cut next to the main limb or trunk until you have cut off the limb further out to reduce the weight. Following proper cutting procedures will prevent stripping the bark from the main member.

n Do not use the pruner for felling or bucking.

n To prevent electrocution, do not operate within 50 ft. of overhead electrical lines.

n Keep bystanders at least 50 ft. away.

MAINTENANCE

WARNING:

When servicing, use only identical replacement parts. Use of any other parts may create a hazard or cause product damage.

WARNING:

Always wear safety goggles or safety glasses with side shields during power tool operation or when blowing dust. If operation is dusty, also wear a dust mask.

WARNING:

Before inspecting, cleaning or servicing the unit (except for carburetor adjustments), shut off engine, wait for all moving parts to stop, and disconnect spark plug wire and move it away from spark plug. Failure to follow these instructions can result in serious personal injury or property damage.

GENERAL MAINTENANCE

Avoid using solvents when cleaning plastic parts. Most plastics are susceptible to damage from various types of commercial solvents and may be damaged by their use. Use clean cloths to remove dirt, dust, lubricant, grease, etc.

WARNING:

Do not at any time let brake fluids, gasoline, petroleum- based products, penetrating lubricant, etc., come in con- tact with plastic parts. Chemicals can damage, weaken, or destroy plastic, which may result in serious personal injury.

All pruner service, other than the items listed in the instruc- tion manual maintenance instructions, should be performed by competent pruner service personnel. (For example, if improper tool is used to hold the flywheel in order to remove the clutch, structural damage to the flywheel could occur and subsequently could cause the flywheel to burst).
