oil fill tube. Use fully synthetic oil: Mobil1 15W-
50. Lift the mower so that the rear wheels are
off the ground. Be careful to support the mower
so that it will not fall or tip while the system is
bled of air. With the bypass valves open and the
engine running, slowly move the control levers
back and forth five or six times. Now close the
bypass valves and with the engine running,
slowly move the control levers back and forth
five or six times. It may be necessary to repeat
the above steps until all the air is purged and the
rear wheels are turning at normal speed. After
purging is complete, adjust the oil level in the
reservoir if necessary.
The battery is 12 volts and is a maintenance free
battery. Charge the battery only if it will not start
the mower properly. Remove the battery from
the mower before charging. Follow the
instructions of the battery charger for proper and
safe charging of the battery.
The underside of the mower deck should be
checked and cleaned twice daily, and more
often if the grass being mowed is lush or wet.
The entire mower should be cleaned daily at the
end of the work day.
Cleaning should be done with a leaf blower or
low-pressure compressed air. Wash with water
only when necessary and do not use a pressure
washer or nozzle as the water can enter
electrical connections causing an electrical
short, rust and corrosion. When washing with
water, do so when the unit has cooled down.
Washing a hot machine can cause various
unseen system damage. If water is used for
cleaning, immediately dry it with a leaf blower or
low-pressure compressed air. Once the wash is
complete, always lubricate and grease all
applicable areas.
