Maintenance
13. Torque the nut to 75-80 in-lb (8-9 N-m), loosen,
then re-torque to 20-25 in-lb (2-3 N-m). Make
sure axle does not extend beyond either nut.
14. Reinstall the seal guards over the wheel hub and
insert wheel into caster fork. Reinstall caster bolt
and tighten nut fully.
Important:
To prevent seal and bearing damage,
check the bearing adjustment often. Spin the
caster tire. The tire should not spin freely
(more than 1 or 2 revolutions) or have any side
play. If the wheel spins freely, adjust torque on
spacer nut until there is a slight amount of drag.
Reapply thread locking adhesive.

remove key or spark plug wire(s). Engage parking
brake.
2. Place a catch pan under the hydro.
3. Carefully clean area around filter. It is important
that no dirt or contamination enter hydraulic
system.
4. Unscrew filter to remove and allow oil to drain
from reservoir.
Important:
Before reinstalling new filter, fill
it with Exmark Premium Hydro oil and apply
a thin coat of oil on the surface of the rubber
seal.
Turn filter clockwise until rubber seal contacts the
filter adapter, then tighten the filter an additional

*May need more often under severe conditions.
6. Loosen filter 1/2 turn and allow a small amount
of oil to leak from the oil filter (this allows air to
be purged from the oil filter and supply hose from
the hydraulic reservoir). Turn filter clockwise
until rubber seal contacts the filter adapter. Then
tighten the filter an additional 2/3 to 3/4 turn.
7. Raise the rear of machine up and support with
jack stands (or equivalent support) just high
enough to allow drive wheels to turn freely.
CAUTION
Raising the mower for service or maintenance
relying solely on mechanical or hydraulic
jacks could be dangerous. The mechanical or
hydraulic jacks may not be enough support
or may malfunction allowing the unit to fall,
which could cause injury.
Do Not rely solely on mechanical or hydraulic
jacks for support. Use adequate jack stands
or equivalent support.
