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.

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

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.

FUEL CAP
WARNING:
A leaking fuel cap is a fire hazard and must be replaced

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.
