1. Stop engine, wait for all moving parts to stop, and
remove key. Engage parking brake.
2. Raise seat.
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 Mobil 1 15W-50 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
2/3 to 3/4 turn.
5. Fill reservoir as stated in Check Hydraulic Oil
Level.
6. Raise the rear of machine up and support with
jack stands (or equivalent support) just high
enough to allow drive wheels to turn freely.
7. Start engine and move throttle control ahead to
full throttle position. Move the speed control
levers to the full speed and run for several
minutes. Shut down machine and recheck oil
level.
Note: Do Not change hydraulic system oil (except
for what can be drained when changing filter), unless
it is felt the oil has been contaminated or been
extremely hot.
Changing oil unnecessarily could damage hydraulic
system by introducing contaminates into the system.

Wheel Hub - Slotted Nut
Torque Specification
Service Interval: After the first 100 hours
When tightening the slotted nut on the wheel motor
tapered shaft:
1. Torque the slotted nut to 125 ft-lb (169 N-m).
2. Check distance from bottom of slot in nut to
inside edge of hole. Two threads (0.1 inch) or less
should be showing.
3. If more than two threads (0.1 inch) are showing
remove nut and install washer (P/N 1-523157)
between hub and nut.
4. Torque the slotted nut to 125 ft-lb (169 N-m).
5. Then tighten nut until the next set of slots line up
with the cross hole in shaft.
6. Replace cotter pin.
Note: Do Not use anti-seize on wheel hub.

Check Engine Coolant Level

Service Interval: Before each use or daily
1. Stop engine and wait for all moving parts to stop.
Make sure unit is on a level surface.
2. Check with engine cold.
3. View coolant level in overflow bottle on the left
side of the engine compartment. Coolant level
should be at the indicator line on the overflow
bottle.
4. If the coolant level is low, open hood or raise
radiator, remove the cap to the overflow bottle
and fill to the indicator line. Units should only be
filled with a 50/50 mix of Dex-Cool© extended
life coolant and water. Dex-Cool© can be
identified by its orange color.
