MAINTENANCE AND STORAGE
Please read the maintenance schedule, found in the
accompanying combined exhaust and evaporative emissions
control warranty statement, and observe these recommended
care operating intervals to extend the life of your engine.
Good maintenance is essential for safe, economical, and
trouble-free operation. It will also help reduce air pollution.
To help you properly care for your engine, the following
pages include routine inspection procedures and simple
maintenance procedures using basic hand tools. Other service
tasks that are more dicult, or require special tools, are best
handled by professionals and are normally performed by a
technician or other qualied mechanic.
Maintenance, replacement or repair of the emissions
control devices and systems may be performed by any
non-road engine repair establishment or individuals.
However, items must be serviced by an authorized dealer
to obtain "no charge" emissions control warranty service.

LUBRICATION
Choose 4-cycle engine oil that meets or surpasses the latest
API service classication SJ or equivalent as labeled on the oil
container. Synthetic oils may be substituted for petroleum-based
oils in extreme temperatures. For temperatures higher than
32°F, use SAE 30 or SAE 10W-30 motor oil. Use SAE 5W-30 or
SAE 10W if temperatures are below 32 °F. DO NOT USE SAE
10W40 MOTOR OIL.
OIL MAINTENANCE
After the rst 20 hours, or after the rst month 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, otherwise changed
weekly. 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.
1. Detach spark plug wire and move away from spark plug. If
the engine uses a battery, disconnect at negative terminal.
SEE FIGURE 9.
2. Remove oil drain plug and empty oil into suitable oil
container. Dispose of oil properly. SEE FIGURE 10.
