Bleeding/Purging the Hydraulic System
IMPORTANT: Air in the hydraulic system is the primary
cause of hydraulic pump failures. Following hydraulic
system service or repair, the hydraulic system MUST be
correctly purged of trapped air before placing the mower
back in operation.
1. To bleed the system make sure the oil tank is full, the
oil must barely cover the fill baffle inside of the tank.
2. Raise the rear unit tires off the floor and place it on
suitable jack stands.
3. Open both pump bypass valves, one on each pump,
two full turns maximum.
4. Sitting in the operator's seat, start the engine and run it
at idle.
5. Slowly cycle the steering control levers full forward and
full reverse for 10 seconds in each direction, 5 or 6
times.
NOTE: The rear tires should rotate, but they'll not be under
load.
6. Shut off the engine, check and add hydraulic oil as
necessary.
7. Close the bypass valves on both pumps. Do not over
tighten.
8. Sitting in the operator's seat, start the engine and run it
at idle.
9. Slowly cycle the steering control levers full forward and
full reverse, 5 or 6 times.
NOTE: It may be necessary to repeat purging procedures
until all air is vented out of the hydraulic system. When the
Pump moves forward and reverse at normal speed and the
reservoir oil remains at a constant level, purging is complete.
IMPORTANT: The rear tires are now rotating under power.
Do not touch or contact them. If they do not rotate after 2-3
cycles, stop immediately. There may still be air in the
system. Let the pumps cool and try purging again from
Step 1.
10. Shut off the engine, lower the unit back to the floor and
check and add hydraulic oil as necessary.
Checking The Hydraulic Hoses
Inspect the hydraulic hoses every 250 hours to ensure they
are in good working order.
Check both the hoses and hose clamps to ensure there is no
wear or damage. If either is found worn or damaged, repair
or replace them at once.
BATTERY MAINTENANCE
Battery
WARNING: AVOID INJURY. Read and
understand entire Safety section before
proceeding.
WARNING: Battery posts, terminals and
related accessories contain lead and lead
compounds, chemicals known to the State of
California to cause cancer and reproductive
harm. Wash hands after handling.
Unit comes equipped from the factory with a
maintenance-free battery that requires no regular
maintenance except cleaning the terminals.
Removing the Battery
WARNING: The battery terminals or metal
tools could short against the metal components
of the mower causing a spark that could ignite
explosive battery gases. When removing the
battery from the mower, do not allow the
battery terminals to touch any part of the
machine. Do not allow metal tools to touch
metal parts of the machine while in contact with
the battery terminals.
Incorrect battery cable routing could damage
the mower or cause a spark that could result in
explosive battery gases being ignited.
Always disconnect the black (negative) battery
cable before disconnecting the red (positive)
battery cable. Always reconnect the red
(positive) battery cable first before
reconnecting the black (negative) battery
cable.
1. Disengage the mower PTO switch, put the steering
control levers in the park position, turn the ignition key
to "Off" and remove the key.
2. Raise the seat and lock it in the upright position.
3. Disconnect the negative battery cable from the battery
terminal.
4. Slide the red boot off of the positive battery terminal
and remove the positive battery cable.
5. Slide the rubber strap out from the battery tray.
Carefully release the strap and slide the opposite end
out of the hooks on the battery tray.
6. Carefully remove the battery. Avoid touching the
terminal posts on any metal parts.
