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, and then remove the fill-
er cap/dipstick and the drain plug.
2. Allow the used oil to drain completely, and
then reinstall the drain plug, and tighten it se-
curely.
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;
pour it on the ground; or down a drain.
3. With the engine in a level position, fill to
the outer edge of the oil filler hole with the
recommended oil.
4. Screw in the filler cap/dipstick securely.

ENGINE OIL RECOMMENDATIONS
Oil is a major factor affecting performance and
service life. Use 4-stroke automotive detergent
oil. SAE 10W-30 is recommended for general
use. Other viscosities shown in the chart may
be used when the average temperature in your
area is within the recommended range.

STORAGE
If possible keep your vibrator horizontal in a
special rack; Otherwise roll up trying to protect
the coupling. It is not recommended to hang it
because the grease can enter the head in pro-
longed storage.
