Maintenance

Adjusting the Throttle

1. Park the machine on a level surface, lower the
cutting units, engage the parking brake, shut off
the engine, and remove the key from the ignition
switch.
2. Position the throttle lever rearward so that it
stops against the control panel slot.
3. Loosen the throttle cable connector on the
injection pump lever arm

4. Hold the injection pump lever arm against the
low idle stop and tighten the cable connector.
5. Loosen the screws securing the throttle control
to the control panel.
6. Push the throttle control lever all of the way
forward.
7. Slide the stop plate until it contacts the throttle
lever and tighten the screws securing the throttle
control to the control panel.
8. If the throttle does not stay in position during
operation, torque the locknut, used to set the
friction device on the throttle lever, to 5 to 6 N∙m
(44 to 53 in-lb).
Note:
The maximum force required to operate
the throttle lever should be 89 N (20 lb).

Hydraulic System
Maintenance

Hydraulic System Safety

•
Seek immediate medical attention if fluid is injected
into skin. Injected fluid must be surgically removed
within a few hours by a doctor.
•
Ensure that all hydraulic-fluid hoses and lines are
in good condition and all hydraulic connections
and fittings are tight before applying pressure to
the hydraulic system.
•
Keep your body and hands away from pinhole
leaks or nozzles that eject high-pressure hydraulic
fluid.
•
Use cardboard or paper to find hydraulic leaks.
•
Safely relieve all pressure in the hydraulic system
before performing any work on the hydraulic
system.
Checking the Hydraulic
Lines and Hoses
Service Interval: Before each use or daily
Check the hydraulic lines and hoses for leaks, kinked
lines, loose mounting supports, wear, loose fittings,
weather deterioration, and chemical deterioration.
Make all necessary repairs before operating.
Checking the Hydraulic
Fluid
Service Interval: Before each use or daily—Check
the level of the hydraulic fluid.
The reservoir is filled at the factory with high-quality
hydraulic fluid. The best time to check the hydraulic
oil is when the fluid is cold. The machine should be in
its transport configuration.
1. Park the machine on a level surface, lower the
cutting units, engage the parking brake, shut off
the engine, and remove the key.
2. Clean the area around the filler neck and cap of
the hydraulic tank
