** Change oil after the first 20 hours of operation or 1 month. Continue to check at intervals of 100 hours or 6 months, whichever occurs first. Severe duty oil
drain intervals: In cold weather conditions (ambient below 40
ºF/4.4 ºC) change engine oil every 6 months or 50 hours of operation to prevent accumulation
of water in the oil. If the unit will be operated continuously in hot ambient conditions (ambient above 85
ºF/29.4 ºC) or operation in an extremely dusty or dirty
environment change the engine oil every 3 months or 50 hours of operation to prevent oil breakdown.
