HYDRAULIC MAST OPERATION

DESCRIPTION OF OPERATION

The Allmand MAXI-LITE tower assembly

consists of a three section telescoping

mast that can be raised and extended by

operating two toggle switches mounted on

the D.C. Control Panel. The lift cylinder

toggle switch operates a solenoid on a

hydraulic pump that pressurizes a cylinder

to raise the mast from the horizontal towing

position to the vertical position. The extend

cylinder toggle switch operates a solenoid

on the same hydraulic pump that pressur-

izes a cylinder that extends the telescoping

sections.

The three section mast assembly can be

rotated from the ground by loosening a knob

and rotating the entire assembly 360° to aim

the lights as necessary.

 ALWAYS CHECK FOR OVERHEAD

OBSTRUCTIONS BEFORE RAISING

AND LOWERING MAST. ALLOW 35'

CLEARANCE. AVOID ALL OVERHEAD

ELECTRICAL WIRES

.

 TO PREVENT INSTABILITY AND HELP

ENSURE SAFE OPERATION, ALWAYS

PROVIDE PROPER GROUND SUP-

PORT BEFORE RAISING MAST.

 BEFORE RAISING MAST, VISUALLY

INSPECT EQUIPMENT FOR DAMAGE

OR WEAR. FAMILIARIZE YOURSELF

WITH THE LOCATION AND FUNCTION

OF ALL OPERATING PARTS BY STUDY-

ING THIS MANUAL. OBSERVE ALL

CAUTION DECALS LOCATED ON

EQUIPMENT.

NOTE: The latch locks the mast in the

vertical position and disengages the

sections allowing the tower assembly

to be rotated to position the lights.

the ground rod. However, it is the user’s

responsibility to determine the require-

ments and/or applicability of local, state,

or national electrical code which governs

the use of the ground rod.

and drive the ground rod fully for adequate

electrical ground, as required by local,

state, or national code.

3. Release the pin that secures the mast to

the rear mast support.

4. Operate the LIFT CYLINDER toggle switch

UP to raise the mast from horizontal to

vertical.

5. Turn black knob counterclockwise and

engage latch in strike plate. Retighten black

knob.

6. Operate the EXTEND CYLINDER toggle

switch UP to raise the lights vertically.

7. To rotate the lights, loosen the black knob
