1. More often under extremely dusty or dirty
conditions.
2. Change engine oil after first 2 hours of
use, then every 25 hours or every
season, whichever comes first.
SERVICE POSITION
1. Remove the gas cap and place a piece of
plastic (a plastic garbage bag works well)
over the tank opening. Reinstall the cap.
This keeps gasoline from spilling out of
the tank.
2. Set the unit swivel in the center position.
3. Loosen the two wing nuts on the lower
handlebar.
4. Tip the unit up onto its back to rest on the
lower handlebar. A 10.2 x 10.2 cm wood
block under the swivel bracket helps
steady the unit by tilting it farther back.
5. When service is complete, place unit in its
normal operating position.
6. Align handlebars and tighten wing nuts.
7. Be sure to remove the plastic from the
gas tank opening.
