SECTION 4 - MACHINE OPERATION
4-6 – JLG Lift – 3120727
DO NOT ATTEMPT TO DRIVE MACHINE ONTO, OFF OF, OR PUSH
MACHINE ONTO A TILTED ROLL-BACK TRUCK BED.
WHEN TOWING OR WINCHING, THE MACHINE’S BRAKES MUST BE
DISENGAGED (SEE SECTION 3-4. CONTROLS AND INDICATOR,
SUB-SECTION “BRAKE RELEASE CONTROL”)
, AND THE EMER-
GENCY STOP BUTTON SET TO THE OFF POSITION, (DEPRESSED).
DO NOT ATTEMPT TO TOW OR WINCH THE MACHINE AT A SPEED
GREATER THAN (2) MPH, OR DAMAGE COULD OCCUR TO THE
MACHINES ELECTRONIC CONTROLLER BOX, (DUE TO HIGH VOLT-
AGE BEING GENERATED BY THE DRIVE MOTORS FEEDING BACK
INTO THE CONTROLLER BOX)
.
RE-ENGAGE THE BRAKES ONCE MACHINE IS IN PLACE WITH
TRUCK BED LEVEL AND READY FOR TIE DOWN.
TIE DOWN BARS ARE PROVIDED ON BOTH ENDS OF THE BASE
FRAME TO SECURE MACHINE TO BED OF TRANSPORT VEHICLE.
Machine Tie-Down
With machine in position to be tied down and brakes
engaged, use the following guidelines for restraining the
machine during transport.
USE OF EXCESSIVE FORCE WHEN SECURING MACHINE (DRIVE
WHEEL LOAD), CAN CAUSE DAMAGE TO THE MACHINES DRIVE
COMPONENTS, I.E. AXLES, AXLE BEARINGS, TORQUE LIMITING
CLUTCH, OR DRIVE GEARS.
1. Secure machine with an adaquate chain attached
through the tie down bars at the front and back of
machine. (See Figure 4-2.)
2. The chain should be securely tightened with a force
of approximately 100 lb. applied two feet from the
pivot handle. (i.e.. the chain is properly tightened
when a 200 lb. load placed on the chain (a 200 lb.
man standing on the chain), just flexes the chain).
Fork-lift Truck Transport
ALWAYS RELEASE THE DRIVE MOTOR BRAKES AND SET THE
EMERGENCY STOP BUTTON TO THE OFF POSITION, (DEPRESSED)
ON THE MACHINE WHEN MANUALLY PUSHING, PULLING, OR
WHEN TRANSPORTING MACHINE BY FORK-LIFT TRUCK. THIS WILL
ALLOW THE DRIVE MOTORS AND GEARS TO ROTATE WITH LEAST
RESISTANCE SHOULD THE DRIVE WHEELS COME IN CONTACT
WITH ANY SURFACE. IF CONTACT OF THE REAR DRIVE WHEELS
DOES OCCUR WHILE FORKLIFT TRUCKING, AT SPEEDS GREATER
THAN 2 MPH, DAMAGE COULD OCCUR TO THE MACHINES ELEC-
TRONIC CONTROLLER BOX, (DUE TO HIGH VOLTAGE BEING GEN-
ERATED BY THE DRIVE MOTORS FEEDING BACK INTO THE
CONTROLLER BOX)
.
ALWAYS REMEMBER TO RE-ENGAGE THE BRAKE SYSTEM
BEFORE MACHINE OPERATION.
As standard equipment, all VP series lift models are
equipped with 7-1/2 in. wide fork-lift pockets running
through the base frame. This allows the machine to be
either transported around a work area or lifted onto a
higher level using a standard fork-lift truck.
NOTE: Fork-lift trucks must be capable of handling the fol-
lowing weights:
