14. Apply a thread-locking adhesive to the second spacer
nut, and thread it onto the axle with the wrench flats
facing outward.
15. Torque the nut to 8 to 9 N-m (75 to 80 in-lb), loosen,
then torque to 2 to 3 N-m (20 to 25 in-lb).
Note: Make sure axle does not extend beyond either
nut.
16.
Install the seal guards over the wheel hub, and insert
wheel into the caster fork.
17.
Install the caster bolt and tighten the nut fully.
Important: To prevent seal and bearing damage, check
the bearing adjustment often. Spin the caster tire. The
tire should not spin freely (more than 1 or 2 revolutions)
or have any side play. If the wheel spins freely, adjust the
torque on the spacer nut until there is a slight amount of
drag. Apply another layer of thread-locking adhesive.
Engine Maintenance
WARNING
Contact with hot surfaces may cause personal
injury.
Keep hands, feet, face, clothing, and other body
parts away the muffler and other hot surfaces.
Servicing the Air Cleaner
Service Interval: Every 250 hours—Replace the primary air
filter.
Every 250 hours—Check the secondary air filter.
Every 500 hours—Replace the secondary air filter.
Note: Service the air cleaner more frequently if operating
conditions are extremely dusty or sandy.
Removing the Filters
1. Disengage the PTO, move the motion-control levers to
the neutral-locked position, and set the parking brake.
2. Stop the engine, remove the key, and wait for all moving
parts to stop before leaving the operating position.
3. Push down to release the retaining clamps on the air
cleaner, and pull the air-cleaner cover off the air-cleaner
body
(Figure
47).
4. Clean the inside of the air-cleaner cover with
compressed air.
5. Gently slide the primary filter out of the air-cleaner
body
(Figure
47). Avoid knocking the filter into the
side of the body.
6. Remove the secondary filter only if you intend to
replace it.
Important: Never attempt to clean the secondary
filter. If the secondary filter is dirty, then the
primary filter is damaged and you should replace
both filters.
7. Inspect the primary filter for damage by looking into
the filter while shining a bright light on the outside of
the filter.
Note: Holes in the filter will appear as bright spots.
Note: If the filter is damaged discard it.
