Rear Attachment Switch
The rear attachment switch is used to raise and lower
therearattachment.Theswitchisattachedtotheright
side motion control handle (Fig. 13). The rear attach-
ment switch is connected to the switch wire harness that
runs through the right side handle and connects to the
main wire harness below the control panel.
When the top of the rear attachment switch is pressed,
the upper solenoid coil on the h ydraulic manifold valve
is energized causing the lift cylinder to extend and raise
the rear attachment. When the bottom of the rear attach-
ment switch is pressed, the lower solenoid coil on the hy-
draulic manifold valve is energized causing the lift
cylinder to retract and lower the rear attachment.
Testing
1. Make sure ignition switch is OFF. Remove key from
ignition switch.
2. Move RH control handle out of the neutral position
and remove two (2) screws that secure switch cap to
right side motion control h andle ( Fig. 14). Carefully slide
switch cap with rear attachment switch and attached
wire harness from control handle.
3. Disconnect wire harness connectors from the rear
attachment switch.
4. Check the continuity of the switch by connecting a
multimeter (ohms setting) across the rear attachment
switch connector terminals.
5. With the switch is its normal, centered position, there
should be no continuity (open circuit) between any of
the switch terminals.
6. With the top of the switch pressed, there should be
continuity (closed circuit) between the lower and cen-
ter switch terminals and no continuity (open circuit)
between the upper and center switch terminals.
7. With the bottom of the switch pressed, there should
be continuity (closed circuit) between the upper and
center switch terminals and no continuity (open circuit)
between the lower and center switch terminals.
8. If testing determines that rear attachment switch is
faulty, replace rear attachment switch.
9. Connect wire harness connectors to rear attachment
switch after testing is complete. Make sure that harness
wires are attached to the switch terminals as shown in
Figure 14. The upper switch terminal should have the
red wire connected to it for proper lift operation.
10.Carefully slide switch cap with rear attachment
switch and attached wire harness into right side control
handle and secure with t wo (2) screws.
