1. With the manual bypass valve open and the
engine running, slowly move the directional
control in both forward and reverse directions
(5 to 6 times), as air is purged from the unit,
the oil level will drop.
2. With the manual bypass valve closed and the
engine running, slowly move the directional
control in both forward and reverse directions
(5 to 6 times). Check the oil level, and add oil
as required after stopping engine.
3. It may be necessary to repeat Steps 1 and 2
until all the air is completely purged from the
system. When the mower moves forward and
reverse at normal speed purging is complete.
Battery Service (if electric start version )
Remove battery (if electric start version) from
machine and fully charge in an open, well-
ventilated area according to the recommendations
of the battery charger manual. The battery is 12
volts. After fully charged, install on mower and
attach battery cables, positive first (from starter
motor) and negative last (from ground).
Cleaning the Mower
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.
MAINTENANCE SERVICE INTERVALS (see chart on following page)
It is very important to keep good maintenance records. Use the hour meter
on the mower to record the hour reading of each maintenance service so
you will not forget how long it has been since you last did certain
maintenance. The more faithful and consistent you are, the longer the
mower will last and hold its value.
