6.6 Bleeding Air from the Hydraulic System
First, make sure the oil level in the reservoir is correct. The oil should be level with the bottom threads
of the oil level port. Use fully synthetic oil: Mobil1 15W-50. 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.
6.7 Hydro Oil Tank Check/Fill
Checking oil
•
Ensure mower is on a level surface.
•
Lift hinged pad and remove hex socket plug from oil level
port on the back of the tank.
•
Hydro oil should be at the bottom of the threads.
Filling oil
•
Lift hinged pad and remove hex socket plug.
•
Using a funnel, fill tank through oil level port until oil
reaches bottom threads of the port.
6.8 Lubrication
The Wright Stander is made with sealed bearings, oil based bushings and with limited grease fittings
therefore only the front caster wheels and caster pivots need to be
greased. (See maintenance chart for service intervals)

grease.
•

out from the bearings.
