OPERATION AND MAINTENANCE
It is the owner’s/operator's responsibility to perform all safety
checks; to make sure that all maintenance for safe operation is
performed promptly; and to have the engine checked by an
authorized dealer periodically. Normal maintenance service and
replacement of parts are the responsibility of the
owner/operator and, as such, are not considered defects in
materials or workmanship within the terms of the warranty.
Individual operating habits and usage contribute to the need for
maintenance service.
Proper maintenance and care of your engine assures a
minimum number of problems and keeps your operating
expenses at a minimum. See your authorized dealer/distributor
for service aids and accessories.
BEFORE STARTING THE ENGINE
Perform the following tasks before trying to start the engine:
CHECKING AND ADDING ENGINE OIL
NOTE:
When adding oil to the engine crankcase in the future,
use only high quality detergent oil rated with API service
classification SF or SG SAE 30 weight. Use no special
additives.
Select the oil’s viscosity grade according to the expected
operating temperature. Do not use SAE 10W-40.
• Above 40°F, use SAE 10W-30 or SAE 30.
• Below 40°F, use synthetic 5W-20 or 5W-30.
Check your engine oil level frequently to avoid possible
damage from running low on oil.
• Place engine on a level surface.
• Clean area around oil fill and remove oil fill cap and
dipstick. (Figure 1 or figure 2)
• Wipe dipstick clean. Reinstall and check oil level on dipstick.
• Slowly fill engine with oil through the oil fill opening
until it reaches the full mark on the dipstick. Stop filling
occasionally to check oil level. DO NOT OVERFILL.

securely.
