Belt Tension Adjustment
The pump drive belt is self-adjusting, and re-
quires no adjustment, just replacement. The
blade drive belt is self-adjusting also and re-
quires no adjustment, just replacement.
How To Move The Mower If The
Engine Won’t Start
Rotate both of the manual “dump” valve levers on
the top of each hydraulic pump about 1/2 turn
counterclockwise. It is important not to over-
tighten these levers. Damage may occur to the
pump if this valve is overtightened.
How To Bleed Air From The
Hydraulic System
Whenever servicing the hydraulic system, it is of
the utmost importance to keep any dirt or debris
from getting into the system. Clean off all parts
before disassembly and assembly. When any of
the hydraulic parts are disconnected or removed
or when the oil is changed, air must be bled from
the system. If air is entrained in the system, loss
of power, excessive heat, and damage to the
hydraulic pumps may occur. First make sure the
oil level in the reservoir is correct. The level
should be between 4"-4.5" below the top of the oil
fill tube. Use synthetic oil: Mobil 1 10W-30 or
AmsOil 10W-40. 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 a few times until all the air
is purged and the rear wheels are turning at
normal speed. After purging is complete, re-
check the oil level in the reservoir and top off if
necessary.
Battery service
The battery is 12 volts and is a maintenance free
battery. Only charge the battery 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 charg-
ing of the battery.
Maintenance Service Intervals
It is very important to keep good maintenance
records. Use the hour meter on the mower and
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 slower it will depreciate.
