Charge Hydraulic System<br />
NOTE: When initially starting the hydraulic system with<br />
new or rebuilt components such as motors or pumps, it<br />
is important that the hydraulic system be charged properly.<br />
Air must be purged from the system and its components<br />
to reduce the chance of damage.<br />
IMPORTANT: Change hydraulic oil filter whenever<br />
hydraulic components are repaired or replaced.<br />
1. Position machine on a level surface, engage parking<br />
brake and remove key from the ignition switch.<br />
2. Make sure all hydraulic connections, lines, and components<br />
are tight.<br />
3. If component failure was severe or the system is contaminated,<br />
flush and refill hydraulic system and reservoir<br />
(see Flush Hydraulic System in this section).<br />
4. Make sure hydraulic reservoir is full. Add correct hydraulic<br />
oil if necessary (see Operator’s Manual).<br />
5. Check control cable to the piston (traction) pump for<br />
proper adjustment, binding, or broken parts.<br />
6. Disconnect wire harness electrical connector from<br />
the engine fuel stop solenoid to prevent the engine from<br />
starting.<br />
7. Make sure traction pedal is in neutral.. Turn ignition<br />
key switch to start; engage starter for ten (10) seconds<br />
to prime hydraulic pumps. Wait fifteen (15) seconds to<br />
allow the starter motor to cool and then repeat cranking<br />
procedure again.<br />
8. Connect wire harness electrical connector to fuel<br />
stop solenoid to allow engine to start.<br />
WARNING<br />
Before jacking up the machine, review and follow<br />
Jacking Instructions in Chapter 1 - Safety.<br />
9. Raise rear wheels off the ground, and place support<br />
blocks under the frame. Chock front wheels to prevent<br />
movement of the machine.<br />
10.Start engine and run it at low idle (1200 -- 1250 RPM).<br />
The charge pump should pick up oil and fill the hydraulic<br />
system. If there is no indication of fill in 30 seconds, stop<br />
the engine and determine the cause.<br />
11.After the hydraulic system starts to show signs of fill,<br />
rotate steering wheel until the steering cylinder rod<br />
moves in and out several times. If the cylinder rod does<br />
not move after 15 seconds, or the gear pump emits abnormal<br />
sounds, shut the engine off immediately and determine<br />
cause or problem. Inspect for the following:<br />
A. Loose filter or suction lines.<br />
B. Blocked suction line.<br />
C. Faulty charge relief valve.<br />
D. Faulty gear pump.<br />
12.If cylinder does move in 15 seconds, proceed to<br />
step 13.<br />
13.Operate the traction pedal in the forward and reverse<br />
directions. The rear wheels should rotate in the proper<br />
direction.<br />
A. If the wheels rotate in the wrong direction, stop<br />
engine, remove lines from side of piston (traction)<br />
pump, and reverse the connections.<br />
B. If the wheels rotate in the proper direction, stop<br />
engine.<br />
14.Adjust traction pedal to the neutral position (see Operator’s<br />
Manual).<br />
15.Check operation of the neutral switch (see Operator’s<br />
Manual).<br />
16.Remove blocks from frame and lower machine to the<br />
ground. Remove chocks from front wheels.<br />
17.If the piston (traction) pump or a wheel motor was replaced<br />
or rebuilt, run the machine so wheels turn slowly<br />
for 10 minutes.<br />
18.Operate machine by gradually increasing it’s work<br />
load to full over a 10 minute period.<br />
19.Stop the machine. Check hydraulic reservoir and fill<br />
if necessary. Check hydraulic components for leaks and<br />
tighten any loose connections.<br />
