Hardware
Check daily. Inspect the entire machine for loose
or missing hardware.
Air filter
See engine manufacturers specifications for
cleaning and replacement intervals.
Hydraulic system
Check oil level in tank daily. Oil level should be 3/
4” to 1” below the top of the tank. Check all fit-
tings, hoses and lines for damage or leaks. Re-
place or repair any questionable lines or fittings.
Change the oil and filter after the first 250 hours of
operation then annually after that. Drain tank and
remove filter, be sure to clean around the tank and
filter head before removal. Replace filter and drain
plug and refill hydraulic tank. Only use MOBIL 1
synthetic oil. FIG - 11
Raise and block up the rear of the machine so the
drive wheels can rotate freely. Start the engine at
the lowest RPM possible, move the motion con-
trol levers forward and run machine for several
minutes. Stop engine and recheck the oil level.
If the wheels do not respond an air lock has oc-
curred within the system. The system must be
bled off of air or let the machine set overnight to
allow the air time to dissipate out of the oil. DO
NOT run the machine with an air lock serious dam-
age can occur to the pumps and wheel motors.

Deck belt
Check every 75 to 100 hours of operation. Check
for severe cracking and large nicks. NOTE: The
belt will show some small cracks in normal op-
eration.
To replace belt lower the deck to its lowest posi-
tion. Remove the foot plate and belt shields. Use
a ratchet with a 9/16” socket on the spring idler
bolt to relieve the tension on the belt. Slide the belt
off of pulley and fully remove the belt. Reverse the
procedure for installation. See the decal on the
top of deck for belt routing information. FIG - 12.
After installation is complete check the belt for
twists.
WARNING!
If a leak is suspected, use a piece of card-
board or wood, NOT your hands. to check
for leaks.
Escaping hydraulic oil under pressure can
have sufficient force to penetrate the
skin, causing serious injury.
If injured by escaping fluid, see a doctor
at once. Serious infection or reaction can
develop if proper medical treatment is not
administered immdediately.
