by loosening the oil drain valve.
CAUTION! Do not fill above the "FULL" mark. Excess
oil will cause a smoking condition and may cause the
engine to overheat.
Oil Change
1. Use only Sentinel Synthetic Propane Engine Oil.
Sentinel is specially formulated for small, hot-tem-
perature engines and provides a longer 250 hour
service interval. If conventional SH or SJ SAE 30 oil
is used instead of Sentinel, scheduled maintenance
MUST revert to every 100 hours to maintain engine
warranty.
2. Change the oil after the first 100 hours of operation
and every 250 hours or 90 days, whichever occurs
first.
3. Start and warm the engine so the oil will drain easily
and completely. Push machine to a level surface.
Stop the engine.
4. Turn off LP cylinder and remove it.
