Electrical Connections; Light Installation; Spinner Sensor; Filling Hydraulic System - New Leader L3020G4 General Manual

ELECTRICAL CONNECTIONS

Connect all electrical control circuits. The supply conductors should be connected to the accessory
terminal of the truck ignition switch through the fifteen amp. circuit breaker provided in the control
panel. All wiring should be approved automotive insulated wire, supported adequately with insulating
ties or straps, and located where it will not interfere with any control or access. Make sure wiring does
not contact any moving parts or sharp edge and is kept away from any hydraulic line or any heated part.

LIGHT INSTALLATION

Light installation must comply with all applicable requirements prescribed by FMVSS/CMVSS 108,
state and local regulations. See "Lights" parts list and instructions below for example of installation.
Use two belt reflector mounts to attach rear red reflectors if mudflaps are not installed. Mount three
lamp cluster to rear endgate. Mount red lamps on back of fenders facing rearward and amber lamps at
the opposite end of fenders facing forward.

SPINNER SENSOR

The spinner sensor must be mounted under the right-hand spinner disc. See "Spinner Sensor" parts list
for illustration. Rotate the disc so that one of the cap screws is directly above the sensor. Position the
sensor 1/8-inch or less below the cap screw and tighten the sensor hardware. If the distance between
the sensor and the spinner cap screw is more than 1/8 inch, the sensor may not get a good RPM
reading. See "Spinner Sensor" parts list for illustration.

FILLING HYDRAULIC SYSTEM

IMPORTANT!
Fill reservoir with hydraulic oil as specified in the "Lubricant Specifications" section of this manual.
Be sure oil is clean, free from dirt, water and other contaminants.
Lubricate all points requiring lubrication per "Lubrication Chart" in this manual.

CHECKING INSTALLATION

See "Initial Start-Up" procedure.
INSTALLATION INSTRUCTIONS CONTINUED
