Oil Service
• Check oil level regularly.
• Be sure correct oil level is maintained. Check every five
to ten hours before starting engine. See oil checking
procedure in the Set-Up section.
Oil Drain
IMPORTANT: Be sure to check engine on a level surface with the
engine stopped. Drain the oil while the engine is still warm to
assure rapid and complete draining.
Note :
1. Remove all fuel from tank by running engine until it stops
from lack of fuel.
2. Snap the small end of oil drain sleeve (if equipped) onto the
engine casting around the oil drain plug. See Fig. 6-1.
3. Remove drain plug and allow oil to drain into a suitable
container. See Figure 6-1.

WARNING:
Before tipping engine or equipment to
drain oil, drain fuel from tank by running engine
until fuel tank is empty.
3. Reinstall the drain plug and tighten it securely, 12-14 Nm
(106.2-123.9 in-lb).
IMPORTANT: Used motor oil may cause skin cancer if repeatedly
left in contact with the skin for prolonged periods. Although this
is unlikely unless you handle used oil on a daily basis, it is still
advisable to thoroughly wash your hands with soap and water as
soon as possible after handling used oil.
NOTE: Please dispose of used motor oil in a manner that is
compatible with the environment. We suggest you take it in a
sealed container to your local service station for reclamation. Do
not throw it in the trash or pour it on the ground.
