LUBRICATION

Choose engine oil that meets or surpasses the latest API service

classification. 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 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 under

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.

IMPORTANT

PROPER POSITION FOR CHECKING OIL LEVEL OR

REFILLING OIL IS FACE DOWN, WITH THE GAS TANK

OF THE MC440 DOWN ON A HORIZONTAL SURFACE.

SEE FIGURE 3A ON PAGE 10. 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 FIGURE 3A 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 (SEE

FIGURE 3B on page 10).

5. Reinsert dipstick or oil fill cap and tighten.
