Change Hydraulic Oil and Filter
NOTICE:
Change the hydraulic oil and oil
filter every season or 100 hours.
1. Clean area around hydraulic supply hose.
2. Place container under oil filter and
hydraulic supply hose to catch oil.
3. Remove hose clamp and disconnect
hose from hydraulic tank.
4. Remove oil filter. See Figure 23.
5. Allow tank to drain.
6. Reinstall hydraulic supply hose
and
tighten hose clamp.
7. Lubricate rubber gasket on new oil filter
with clean hydraulic oil.
8. Spin new oil filter onto filter housing until it
makes contact. Tighten oil filter another
1/2 turn.
9. Add hydraulic oil.
10. Check hydraulic oil level.
11. Properly dispose of waste oil.
Purge Air From Hydraulic System
1. With the engine running, extend the
hydraulic cylinder out fully and then
retract fully.
2. Repeat 4 – 5 times. Erratic movement in
the hydraulic cylinder indicates that there
is air in the system.
3. Stop the engine and check the hydraulic
oil level. Add if necessary.
4. Repeat extending and retracting of
hydraulic cylinder unit motion is
consistent and smooth in both directions.
5. Ensure that hydraulic oil is at proper level.
IMPORTANT:
At this point a large amount of
hydraulic oil has been drawn into the
hydraulic cylinder and hoses. Be sure to refill
the oil reservoir to prevent pump damage.
CHECK TIRE PRESSURE
Check tire pressures and inflate to
recommendation. See
Figure 22

WARNING:
AVOID INJURY.
Explosive separation of tire and
rim parts is possible.
• DO NOT inflate tires above
maximum pressure listed on tire
sidewalls.
• DO NOT inflate tires with a
compressor; use a hand pump.
• DO NOT stand in front of tire
assembly when inflating. Use a
clip-on chuck and extension
hose long enough to allow you
to stand to one side.
• DO NOT mount a tire without
proper equipment and
experience.
