Changing Engine Oil
Check engine oil level regularly - WHILE THE UNIT IS IN A LEVEL POSITION.
Check the oil before each usage. Stop engine and wait several minutes before
checking oil level. With engine level, the oil must be about a 1/4 inch below the
top of the yellow oil fill cap opening. Change oil after the first five hours of
operation and every 25 hours thereafter. Refer to the engine manual enclosed
with this unit for additional information on your engine.
Bag Maintenance
Keep the bag clean by occasionally
washing it by hand with mild soap and
water. A clean bag improves air flow and
results in better vacuuming performance.
Do not wash the bag in an automatic
washer. Do not use a cleaner which
contains bleach. Allow the bag to dry
