Switch Installation and Testing
1. Route the wiring from the dash, through the bezel,
then connect the wiring to the auxiliary hydraulic
pressure release switch (1) as labeled during switch
removal.
2. Make sure the symbol (4) is at the bottom of the
switch (1), then press or “snap” the switch into place
in the bezel.
3. If the vehicle has dual batteries, connect both
negative battery cables (9 and 10) to both batteries.
Connect the lower negative battery cable (9) to the
negative (-) terminal on the lower battery (11). Swing
the upper battery box (14) in and make sure that the
lip (13) on the upper battery box slides below the
knob (12). Secure in place with the knob.
4. Lower and lock engine cover. To release and lower
the engine cover (7) from the fully raised position, lift
up slightly on the cover and push the upper part of
the right gas shock (8) (orange tab) to the left. Line
up the upper part of the shock lock tube with the
lower part of the gas shock and pull the cover down
to the closed position.
5. The ignition switch must be in the RUN position. The
engine can be either idling or shut OFF. Press and
hold the momentary auxiliary hydraulic pressure
release switch for two seconds to release trapped
pressure in the auxiliary hydraulic system. If the two
auxiliary hydraulic couplings can now be easily
connected or disconnected, the switch is operating
properly.
