LUBRICATION
Choose engine oil that meets or surpasses the latest API
service classification. For temperatures higher than 32º F, use
SAE 30 or 10W-30 motor oil. Use SAE 5W-30 if temperatures are
below 32º F.
OIL MAINTENANCE
After the first five hours of operating a new Viper engine the
oil should be replaced, and every 50 hours of operating time
thereafter. The oil should be changed every 25 hours if used
under severe conditions, such as in high temperatures or un-
der heavy loads. Check oil periodically; do not overfill!
CHANGING OIL
Be sure the engine is not operating and is located on a level
surface before checking or refilling oil. Engine should be warm
for easy removal of oil.
1. Flip the ON/OFF switch to the OFF position.
2. Unscrew oil drain screw and empty oil into suitable oil con-
tainer. (SEE FIGURE 3 on PAGE 10) Dispose of oil properly.
3. Reinsert drain screw and remove oil dipstick.
4. Fill with appropriate oil to “FULL“ or top line of dipstick; oth-
erwise to top thread of oil fill hole.
5. Reinsert dipstick or oil fill cap and tighten.
