Maintenance
filter, are removed or any of the hydraulic lines are
disconnected.
1. Stop engine and wait for all moving parts to stop.
Raise the rear of the machine up onto jack stands
high enough to raise the drive wheels off the
ground.
2. Check oil level as stated in Check Hydraulic Oil
Level section.
3. Start engine and move throttle control ahead to
full throttle position. Move the speed control
lever to the middle speed position and place the
drive levers in the “drive” position.
4. Open the drive wheel release on each pump.
5. With the machine running, stroke the drive levers
from forward to reverse several time, slowly.
Then, retighten the drive wheel release valves.
Note:
If either drive wheel does not rotate, it
is possible to assist the purging of the charge
pump by carefully rotating the tire in the forward
position.
6. If either drive wheel still does not rotate, stop and
repeat steps and above for the respective pump. If
wheels rotate slowly, the system may prime after
additional running. Check oil level as stated in
Check Hydraulic Oil and Tank Level section.
7. Allow the machine to run several minutes after
the charge pumps are “primed” with drive system
in the full speed position. Check oil level as stated
in
Check the Hydraulic Oil Level section.
8. Check hydro drive linkage adjustment as stated in
Hydro Drive Linkage Adjustment section in
Adjustments.
Check Tire Pressures
Service Interval: Every 50 hours
1. Stop engine, wait for all moving parts to stop, and
remove key. Engage parking brake.
2. Check tire pressure in drive tires.
3. Inflate all tires to 18 psi (124 kPa).
Check Spreader System
Service Interval: Every 50 hours
Spray the hopper cables, accuway cable, and the
deflector shield cable with silicone spray if needed.
Clean the bottom of the hopper with a wire brush
and clean off any fertilizer if needed.
Change out the hopper bottom bushing or the
impeller if needed.
Check Sprayer System
Service Interval: Every 50 hours
1. Stop engine, wait for all moving parts to stop, and
remove key. Engage parking brake.
2. Check all hoses, nozzles, and fittings for leaks.
3. Check nozzle strainers and in-line strainers.
4. Replace as needed.
Check In-line Filter
Service Interval: As required
Periodically check the in-line filter for any debris in
the screen. If debris is present, this can create erratic
pressure spikes and/or not allow the proper flow
through system. After clearing any debris, ensure that
gasket remains intact and tighten in-line filter cap (if
not installed properly, this will allow air to get in the
system and system will lose or not create pressure).
