MAINTENANCE
HYDRAULIC FILTER
The hydraulic filter keeps the machines hydraulic system clean to a level of 10 microns. The hydraulic fluid filter is located just inside the left rear frame. The filter should be changed every 500 hours.
TO REPLACE FILTER ELEMENT:
1.Stop the engine and set the parking brake.
2.Open the seat support.
3.Unthread and discard the hydraulic fluid filter element.
4.Apply a thin coat of hydraulic fluid to the seal of the new hydraulic fluid filter element.
5.Thread and hand tighten the new hydraulic fluid filter element on the filter head.
6.Close the seat support.
7.Operate the machine and check for leaks. Correct any leaks found.
8.Check the hydraulic fluid reservoir level and fill as required.
DIRECTIONAL CONTROL SYSTEM
(Refer to the Electrical Control Group in the Parts section)
The directional control system controls the direction and speed of the machine. The system is made up of the directional pedal, the throttle box, the transistorized controller and contactors. The controller, located in the electrical drive compartment, is sealed and can only be serviced by trained service personnel.
Do not use a pressure washer to clean the inside of the electrical drive compartment.
When servicing machine, disconnect battery connections before working on machine.
DIRECTIONAL CONTROL PEDAL ADJUSTMENT (Refer to the Console Group in the Parts section) The directional control pedal is designed to prevent driver fatigue. However if a different pedal angle is preferred, these directions should be followed.
1.Raise rear cover.
2.Disconnect batteries from machine.
3.Locate and remove the directional control pedal stop bolt.
4.Locate the linkage rod beneath the directional control pedal.
5.Adjusting the length of the linkage rod controls the pedal angle. Shortening the linkage rod causes the pedal to have a flatter angle with the floor. Lengthening the linkage rod causes the pedal to have a steeper angle.
6.To change the length of the linkage rod, disconnect the upper end of the linkage rod from the forward/reverse arm.
7.Loosen the locking nuts on both ends of the threaded portion of the linkage rod.
8.Turning the balljoint changes the length of the linkage rod, be sure that there is a minimum of 5/16” of threaded rod engaged in each of the balljoints.
9.When the new length is established, reconnect the upper balljoint to the forward/reverse arm.
10.Tighten the two locking nuts on the threaded portion of the linkage rod.
11.Reposition the directional foot pedal stop bolt.
12.The stop bolt must be adjusted so that the directional foot pedal comes in contact with the stop while there is still a small amount of travel remaining in the throttle arm. This is done to prevent heavy foot pressure from damaging the throttle unit.
THROTTLE “NEUTRAL POSITION” ADJUSTMENT (Refer to the Console Group in the Parts section)
The throttle is automatically returned to its neutral position by a spring centering system. If the machine tends to creep forward or reverse when the operators foot is removed from the directional foot pedal, the throttle “neutral position” may require adjustment as described below:
1.Turn off machine and set parking brake.
2.Raise the rear cover.
3.Disconnect the batteries from the machine.
4.Remove the drive motor dust cover.
5.Locate the throttle and spring centering assembly.
6.Disconnect the linkage rod from the throttle arm.
7.With the throttle arm free, the throttle will return to its neutral position using its internal centering spring.
8.Position the linkage rod balljoint over the hole in the throttle arm. The balljoint should slide into the hole without repositioning the throttle arm.
9.If required, shorten or lengthen the linkage rod until proper engagement occurs.
10.Reattach linkage rod to the throttle arm.
11.Install the drive motor dust cover.
12.Connect batteries.
13.Lower hopper.
