blade drive belt is self-adjusting also and
requires 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 ½ turn
counterclockwise. It is important not to over
tighten these levers. Damage may occur to the
pump if this valve is over tightened.
Bleeding 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 fully synthetic oil: Mobil 1 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.
