Engine Oil Level Check
Check the engine oil level before each use, or every 10 hours if
operated continuously. Rest the trimmer on a level surface, with the
engine stopped and in an upright position.
1. Remove the filler cap/dipstick and wipe it clean.
2. Insert and remove the dipstick without screwing it into the filler
opening. Check the oil level shown on the dipstick.
3. If the oil level is low, fill to the edge of the oil filler hole with the
recommended oil (see page 18). To avoid overfilling or underfilling,
be sure the engine is in a level position, as shown.
NOTICE
Running the engine with too little or too much oil can cause engine
damage.
4. Screw in the oil filler cap/dipstick securely.
Engine Oil Change
Drain the used oil while the engine is warm. Warm oil drains quickly
and completely.
1. Place a suitable container below the engine to catch the used oil,
then remove the filler cap/dipstick and drain the used oil through
the filler opening. Allow the used oil to drain completely.
Please dispose of used motor oil in a manner that is compatible
with the environment. We suggest you take used oil in a sealed
container to your local recycling center or service station for
reclamation. Do not throw it in the trash or pour it on the ground or
down a drain.
2. With the engine in an upright position, fill to the edge of the oil filler
hole with the recommended oil.
3. Screw in the filler cap/dipstick securely.
