C. flange Bearings
The Flange Bearings must be lubricated with
grease before every use or every 4 hours of
run time, whichever comes first, or warranty of
Flange Bearings will be voided.
d. machine & engine maintenance
1. Refer to engine manufacturer’s Owners
Manual and comply completely with the
instructions. Change the oil and filter according
to the engine Owners Manual.
2. Keep a good service log on each machine with
the date, hour meter reading, type(s) of service
performed and the name of the person who
performed them.
3. Clean the entire unit after each use. When
cleaning the unit, check for possible loose
nuts and bolts.
4. The foam engine dust filter should be
removed and cleaned periodically by shaking
out the accumulated dust and rinsing with
water and a mild detergent. Squeeze out excess
water (do not wring out). Allow the filter to air

clean may result in engine overheating.
Changing Gear drive lubricant
After the first 100 hours of operation, drain out
initial oil, flush out the gear case with an approved
nonflammable, non-toxic solvent and refill.
Thereafter, oil should be changed at least every
500 operating hours, or every 6 months, whichever
comes first, with Mobilgear 630 oil or equivalent.
e. maintenance schedule
Repairs and adjustments to the fuel system must be
performed by an authorized, properly trained service
technician. To keep the machine in good working
condition, follow the daily, weekly and monthly
maintenance procedures listed below. Keeping the
machine clean and free of accumulated dust, lint and
oil allows free air to flow across the engine and
proper cooling. Always use clean recoil dust filters.
These can be cleaned by washing them in flowing
water and shaking them dry. Keep a log book of
maintenance and/or repairs.
