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. 
 
Battery Service 
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. 
 
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.
