LUBRICATION
Choose engine oil that meets or surpasses the latest API service
classication. For temperatures higher than 32º F, use 10W-30
motor oil. Use SAE 5W-30 if temperatures are below 32º F.
OIL MAINTENANCE
After the rst ve hours of operating a new Viper® engine the oil
should be replaced, and every 50 hours of operating time there-
after. The oil should be changed every 25 hours if used under
severe conditions, such as in high temperatures or under heavy
loads. Check oil periodically; do not overll!
CHANGING OIL
Be sure the engine is not operating and is located on a level
surface before checking or relling oil. Engine should be warm
for easy removal of oil.
IMPORTANT
PROPER POSITION FOR CHECKING OIL LEVEL OR RE
FILLING OIL IS FACE DOWN, WITH THE GAS TANK OF
THE CULTIVATOR DOWN ON A HORIZONTAL SUR
FACE. SEE OPERATION SECTION FOR CHECKING AND
ADDING OIL. FAILURE TO MAINTAIN THIS POSITION
CAN RESULT IN OVER FILLING THE ENGINE WITH OIL
WHICH WILL IMPAIR THE ENGINE’S PERFORMANCE.
STEPS FOR CHANGING OIL
1. Flip the ON/OFF switch to the OFF position.
2. Unscrew oil drain screw and empty oil into suitable oil
container (See Operation Section for checking and adding
oil). Dispose of oil properly.
3. Reinsert drain screw and remove oil dipstick.
4. Fill with appropriate oil to “FULL“ or top line of dipstick (See
Operation Section for checking and adding oil).
5. Reinsert dipstick or oil ll cap and tighten.
