Hydraulic Lift Lever Interlock Switch - Toro Workman HDX Service Manual

Hydraulic Lift Lever Interlock Switch

The lift lever interlock switch is a normally open proximity
switch that is attached to the control lever support (Fig.
14). The interlock switch is in its normal open position
whenever the hydraulic lift lever is moved away from the
neutral position. When the lift lever is in the neutral posi-
tion, the retainer pin that attaches the lift lever link to the
lift valve is positioned close to the interlock switch caus-
ing the switch to close. The closed bed lift switch is used
in the starting interlock system to make sure that the hy-
draulic lift circuit is disengaged during engine starting.
Testing
1. Park vehicle on a level surface, shut engine off, re-
move key from ignition switch and apply parking brake.
2. Remove knobs from control levers, then remove con-
trol plate assembly from seat base (Fig. 15).
3. Locate the lift lever interlock switch (Fig. 14).
4. Disconnect the wire harness connector from the lift
lever interlock switch.
5. With the use of a multimeter (ohms setting), test for
continuity across the two (2) switch terminals. There
should be continuity (zero ohms) when the lift lever is
in the neutral position and there should not be continu-
ity (infinite ohms) when the lift lever is out of the neutral
position.
6. After switch testing is completed, connect the wire
harness connector to the lift lever interlock switch. Se-
cure panel to seat base.
7. Secure center console control plate to seat base with
removed screws. Torque screws a maximum of 12 in- -lb
(1.3 N- -m). Install knobs on control levers.
