MAINTENANCE
Pump belt
Check belt every 100 hours for excessive wear.
To replace belt. Relieve tension on the deck belt
and remove deck belt from clutch. See deck belt
instructions on previous page. Loosen bolt on the
clutch tie down and rotate out of the way. Using a
1/2” drive ratchet inserted into the square hole in
the pump idler arm relieve the tension on the pump
belt and remove belt. To reinstall belt. Swing pump
idler pulley out toward engine to route belt around
it. Then route belt around right side pulley first as
you are looking up from the underside of machine.
Reinstall idler spring and use the ratchet to rotate
idler so the belt may be installed all the way around
the last pulley.

Winter storage
To prepare the machine for storage. Clean the
machine, especialy under the deck. Touch-up the
paint or spray the underside of deck with a light
coat of oil.
Inspect the machine for damage and loose hard-
ware.
Change the oil.
Drain the fuel system or add stabilizer to fuel. Make
sure to run the machine after to circulate stabi-
lizer throughout system.
Remove the plugs and add 1 tablespoon of oil in
each cylinder. Install plugs and crank the engine
two or three revolutions.
Grease all zerks.
Remove battery and store inside and protect it
from freezing temperatures.
Caster Wheels
Check every 200 hours. Lift front of unit off of
ground so caster wheels can rotate freely. Tighten
caster bolt then back off 1/2 turn. Check that wheel
rotates freely. If wheel does not rotate freely back
the caster bolt off in 1/4 turn increments until wheel
rotates freely.
NOTE: DO NOT add any type of tire liner or foam
fill material to the tires. Excessive loads created
by foam filled tires will cause premature failures.
Only use O.E.M. specified tires. Foam filling tires
or solid tires will void the warrany.
Fuel filter
Replace every 500 hours or annually. In extremely
dirty conditions replacement may need to be at
shorter intervals.
