Maintenance
6. Clean around oil fill cap and remove cap. Fill to
specified capacity and replace cap.
7. Remove drain hose, close fuel tank, and lower
hopper.
8. Use oil recommended in engine owner's manual.
Do Not overfill. Start the engine and check for
leaks.
9. Wipe up any spilled oil from engine deck
mounting surfaces.

Check Hydraulic Oil Level

Service Interval: Every 40 hours
WARNING
Oil spilled or vented from an overfilled
hydraulic reservoir onto the PTO brake band
will cause a longer stopping time for the deck
and blower rotating components. The deck
and blower rotating components can cause
serious injury.
• Wait for all moving parts to come to a
complete stop before servicing.
• Do Not overfill the hydraulic reservoir.
Carefully fill only to the recommended
level.
• Replace the brake band if it becomes
contaminated with oil.
1. Stop engine and wait for all moving parts to stop.
Engage parking brake.
2. Tilt hopper 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 only
Exmark Premium Hydro oil. Replace hydraulic
reservoir cap and tighten until snug. Do Not
overtighten. Do Not overfill.
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. Do Not
overfill.

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.
3. Inflate drive tires to 15 psi (103 kPa).
4. The rear caster tire is semi-pneumatic and does
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. Tilt hopper up and check pump and PTO drive
belts for wear, cracking, or contamination.
3. Belts are spring tensioned and no adjustment is
necessary unless belts are replaced. See PTO
Belt Replacement and Pump Drive Belt
Replacement sections for belt replacement.

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 Lubrication Chart for fitting locations
and lubrication schedule.
