cooler hoses so they do not snap pump fans. The
debris screen should be removed before blowing
cooler out from the bottom. When reinstalling the
cooler, make sure the cooler hoses do not interfere
with the fans and ensure the cooler housing is secure
under the four tab points of the cooler bracket.

How to Move the Mower if the Engine Won’t
Start
Rotate both of the manual “release” valve levers on
the rear 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. 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 2” – 2 1/2” 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.
Fuel Evaporation System
All Wright Stander ZK’s need to have this mandatory
feature.
• Do Not alter or remove.
• Do Not fill past the “Max Fill Level” line shown in
figure.
• Over-filling could result in clogging the roll-over
vent and/or contaminating the purge canister.
• The vapor canister is located under the dash.
• Inspect and clean dust filter every 500 hrs or
annually.
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.
