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
solvents 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
WARNING:
A leaking fuel cap is a fire hazard and must be replaced
immediately.
The fuel cap contains a non-serviceable filter and a check
valve. A clogged fuel filter will cause poor engine performance.
If performance improves when the fuel cap is loosened,
check valve may be faulty or filter clogged. Replace fuel
cap if required.
