Maintenance
2. Tilt seat up.
3. Clean area around hydraulic reservoir cap and
remove cap. Oil level should be to the top of the
baffle inside the tank. If not, add oil. Use Exmark
Premium Hydro oil. Replace hydraulic reservoir
cap and tighten until snug. Do Not overtighten.
Note: The baffle is labeled "HOT" and
"COLD". The oil level varies with the
temperature of the oil. The "HOT" level shows
the level of oil when it is at 225°F (107°C). The
"COLD" level shows the level of the oil when
it is at 75°F (24°C). Fill to the appropriate level
depending upon the temperature of the oil. For
example: If the oil is about 150°F (65°C), fill to
halfway between the "HOT" and "COLD" levels.
If the oil is at room temperature (about 75°F
(24°C)), fill only to the "COLD" level.
Check Auxiliary Hydraulic
Oil Level
Service Interval: As required
Note: Check the auxiliary hydraulic oil level if there
is evidence of a leak or the hydraulic cylinder does
not perform normally.
1. Retract the hydraulic cylinder.
2. Stop engine and wait for all moving parts to stop.
3. Tilt the seat forward.
4. Locate the auxiliary hydraulic power unit reservoir
(see Figure 9).

1. Auxiliary hydraulic reservoir plug
5. Clean area around the reservoir plug and remove.
Oil level should be up to the reservoir plug hole.
If not, add oil. Use only Exmark Premium Hydro
oil. Replace reservoir plug and tighten until snug.
Do Not overtighten.

Check Tire Pressures

Service Interval: Every 40 hours
1. Stop engine, wait for all moving parts to stop, and
remove key. Engage parking brake.
2. Check tire pressure in drive tires.
Bar lug drive tires should be inflated to 9 psi (62
kpa).
Turf drive tires should be inflated to 13 psi (90
kpa).
3. The rear caster tires are semi-pneumatic and Do
Not need to be inflated.
Note: Do Not add any type of tire liner or foam
fill material to the tires. Excessive loads created by
foam filled tires may cause failures to the hydro drive
system, frame, and other components. Foam filling
tires will void the warranty.

Check Condition Of Belts

Service Interval: Every 40 hours
1. Stop engine, wait for all moving parts to stop, and
remove key. Engage parking brake.
2. Check pump and PTO drive belts.
3. Belts are spring tensioned and no adjustment is
necessary. See Pump Drive Belt Tension and
Replacement sections in Adjustments.

Lubricate Grease Fittings

Note: See chart for service intervals.
1. Stop engine, wait for all moving parts to stop, and
remove key. Engage parking brake.
2. Lubricate fittings with one to two pumps of
NGLI grade #2 multi-purpose gun grease.
Refer to the following chart for fitting locations
and lubrication schedule.
