Operating Precautions

■ Make sure the chain and

sprocket are correctly adjusted

before operating the pruner

(see page 15 for adjustment

procedures). Never attempt

chain adjustment with the

engine running!

■ Always make sure the cutting

attachment is properly

installed and firmly tightened

before operation.

■ Never use a cracked or

warped guide bar: replace it

with a serviceable guide bar

and make sure it fits properly.

■ If a saw blade should bind fast

in a cut, shut off the engine

immediately. Push the branch

or tree to ease the bind and

free the blade.

■ Make sure there are no missing

or loose fasteners, and that the

ignition switch and throttle

controls are working properly.

■ Before starting the engine,

make sure the saw chain is

not contacting anything.

■ Make sure there is always

good ventilation when operat-

ing the pruner. Fumes from

engine exhaust can cause

serious injury or death. Never

run the engine indoors!

■ Do not operate the pole pruner

with the muffler removed.

■ When cutting a limb that is

under tension, be alert for

springback so that you will not

be struck by the moving limb.

■ 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.

■ Stop the unit immediately if it

suddenly begins to vibrate or

shake. Inspect for broken,

missing or improperly in-

stalled parts or attachments.

■ Never transport the pruner

nor set it down with the

engine running. An engine

that’s running could be

accidentally accelerated

causing the chain to rotate.

WARNING!

Use Good Judgement

WARNING!

Minimize the Risk of Fire

■ NEVER smoke or light fires

near the unit.

■ ALWAYS stop the engine and

allow it to cool before refuel-

ing. 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.
