Maintenance
Change Fuel Filter
Service Interval: As required
A fuel filter is installed in the fuel line between the
fuel tank and the engine. Replace when necessary.
Note:
It is important to reinstall the fuel line hoses
and secure in place, the same way as originally
installed at the factory, to keep the fuel line away
from components.
Change Hydraulic Filters and
Fluid
Service Interval: After the first 100 hours
Every 500 hours/Yearly
(whichever comes
first) thereafter
(Every 250 hours/Yearly
if using Mobil 1 15W-50
thereafter)
1.
Stop engine, wait for all moving parts to stop, and
remove key or spark plug wire(s). Engage parking
brake.
2.
Place a catch pan below the hydros and allow oil
to drain from the reservoir.
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 finish
draining from drive system.
Important:
Before reinstalling new filters,
apply a thin coat of Premium Hydro Oil on
the surface of the filters rubber seal.
Turn the filters clockwise until rubber seal
contacts the filter adapter then tighten the filter
an additional 3/4 to 1 full turn.
5.
Reinstall the drain plug.
6.
Fill the hydraulic reservoir until fluid is halfway up
the sight window.
Exmark Premium Hydro Oil is recommended.
Refer to the chart for an acceptable alternative:

*Every 250 hours
thereafter
*May need more often under severe conditions.
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.
8.
Start engine and move throttle control ahead to
1/2 throttle position. Disengage parking brake.
A.
With the engine running, slowly move the
directional control in both forward and
reverse directions (5 to 6 times). Check the oil
level, and add oil as required after stopping
the engine.
B.
It may be necessary to repeat step A. until all
the air is completely purged from the system.
When the transaxle operates at normal noise
levels and moves smoothly forward and
reverse at normal speeds, then the transaxle
is considered purged.
Note:
Do Not
change the hydraulic system oil
(except for what can be drained when changing filter
and removing the drain plugs), unless it is felt the oil
has been contaminated or been extremely hot.
Changing oil unnecessarily could damage hydraulic
system by introducing contaminants into the system.
