WARNING:
When servicing, use only identical replacement parts.
Use of any other parts could create a hazard or cause
product damage.
WARNING:
Always wear eye protection with side shields marked to
comply with ANSI Z87.1, along with hearing protection.
Failure to do so could result in objects being thrown into
your eyes and other possible serious injuries.
WARNING:
Before inspecting, cleaning, or servicing the machine,
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 lubricants, etc., come in con-
tact with plastic parts. Chemicals can damage, weaken or
destroy plastic which may result in serious personal
injury.
You can often make adjustments and repairs described here.
For other repairs, have the trimmer serviced by an authorized
service dealer.
WARNING:
Blades are sharp. When handling the blade assembly,
wear non-slip, heavy-duty protective gloves. Do not place
your hand or fingers between blades or in any position
where they could get pinched or cut. NEVER touch blades
or service unit with the spark plug wire connected.

REPLACING BLADES

See Figure 7.
Periodically inspect the blades for damage and wear. Always
use the manufacturer's specified replacement blades.
 Stop the engine and disconnect the spark plug wire.
 Place the hedge trimmer upside down on a workbench
and remove the gear box cover screws.
MAINTENANCE
 Remove the gear box cover and set aside.
 Remove the blade screws.
 Remove the old blade.
 Install the new blade and reinstall blade screws to
secure.
 Install the gear box cover and reinstall gear box cover
screws to secure.

LUBRICATING THE BLADE

See Figure 8.
For easier operation and longer blade life, lubricate the hedge
trimmer blade before and after each use.
 Stop the engine and disconnect the spark plug wire.
 Lay the hedge trimmer on a flat surface. Apply light weight
machine lubricant along the edge of the top blade.
If you will be using the hedge trimmer for an extended period,
it is advisable to lubricate the blade during use.
NOTE: Do not lubricate while the hedge trimmer is running.
 Stop the engine and disconnect the spark plug wire.
 Lubricate the hedge trimmer as described above.
 Reconnect the spark plug wire and resume use.

CLEANING THE HEDGE TRIMMER

 Stop the engine and disconnect the spark plug wire.
 Slide the scabbard over the blade.
 Clean dirt and debris from the body of the hedge trimmer,
using a damp cloth with a mild detergent.
NOTE: Do not use any strong detergents on the plastic
housing or the handle. They can be damaged by certain
aromatic lubricants such as pine and lemon, and by sol-
vents such as kerosene.
CLEANING THE AIR FILTER SCREEN
See Figures 9 - 10.
For proper performance and long life, keep air filter clean.
 Remove the air filter cover by pushing down on the latch
with your thumb while gently pulling on the cover.
 Brush the air filter screen lightly to clean.
 Replace the air filter cover by inserting the tabs on the
bottom of the cover into the slots on the air filter base;
push the cover up until it latches securely in place.
NOTE: For best performance, replace annually.
FUEL CAP
Check for fuel leaks. A leaking fuel cap is a fire hazard
and must be replaced immediately. If you find any leaks,
correct the problem before using the product. Failure
to do so could result in a fire that could cause serious
personal injury.
