HYDRAULIC LIFT VERTICAL MAST OPERATION
DESCRIPTION OF OPERATION
The Allmand MAXI-LITE V Series hydraulic lift tower assembly consists of a seven sec­tion telescoping mast which can be extended by operating a single hydraulic cylinder. The light bar assembly can be rotated into position by releasing the light bar park pin. To release the park pin, pull the ring and turn it 90 degrees so that the pin remains in the retracted position. The light bar is designed to rotate with enough resistance so that the bar will stay in the desired position once the operator has directed the lights on the work zone. if the light bar rotates too easily or does not stay in position, remove the cap plug from the center of the light bar cover and tighten the nut to achieve the desired resistance and replace the cap plug.
SAFETY WARNING!
TO SET UP TOWER AND RAISE LIGHTS
1. Extend both side outrigger jacks, rear jack and tongue jack to stabilize and level the trailer.
NOTE: Jacks should be placed only on
rm footing.
SAFETY WARNING!
THE SUPPLEMENTAL GROUND ROD IS
A SAFETY DEVICE THAT MAY REDUCE THE CHANCE OF PERSONAL INJURY
FROM STRAY ELECTRICAL CURRENT
Therefore, Allmand recommends using the ground rod. However, it is the user’s responsibility to determine the require­ments and/or applicability of local, state, or national electrical code which governs the use of the ground rod.
.
 ALWAYS CHECK FOR OVERHEAD OB-
STRUCTIONS 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 SUPPORT 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 STUDYING THIS MANUAL. OBSERVE ALL CAU­TION DECALS LOCATED ON EQUIPMENT
.
2. Attach the ground rod to the grounding lug, and drive the ground rod fully for adequate electrical ground, as required by local, state, or national code.
3. Start engine.(NOTE: Tower may be raised and lowered as needed without engine run­ning.)
4. While the tower is still in the down position, position the light bar and lamps so they are aimed at the work zone and tilted at the ap­proximate angle to get maximum coverage once the tower is raised.
5. Stand clear of the tower when raising and lowering the lights.
8
Page 9
HYDRAULIC LIFT VERTICAL MAST OPERATION
6. Operate the hydraulic lift switch to the “up” position to raise tower to the de­sired height.
7. If lights need to be adjusted for better lighting of the work zone after raising the tower, lower the tower using the “down” switch position and make desired adjust-
ments to the light bar and light xtures.
Raise the tower into position. Repeat this step if necessary.
SAFETY WARNING!
 VISUALLY INSPECT EQUIPMENT FOR
DAMAGE BEFORE OPERATING. ALLOW ADEQUATE CLEARANCE AROUND TRAIL­ER FOR TOWER AND INSURE THAT NO PERSONS ARE STANDING IN UNDER THE LIGHTS WHEN LOWERING.
5. Reposition the lamp xtures for transport
by pulling them down into the lowest posi­tion and face the
xtures toward the center of the trailer.
6. Remove ground rod from earth. Discon­nect wire from ground lug and secure in trailer
7. Raise jacks and rear stand, retract outrig­gers and secure for towing
NOTE: Ensure the detent pins are prop-
erly engaged in the outriggers before
towing.
TO LOWER TOWER AND LIGHTS
1. Turn off lights.
2. Operate the hydraulic lift switch in the down position to lower the lights to the lowest vertical position. When tower reaches the bottom, run switch for three additional seconds to ensure that the tower is at it’s lowest possible position.
3. Stop engine.
4. Rotate the light bar into the transport park position (in line with trailer) and engage the park pin by twisting on the park pin ring until the plunger is released and the pin engages the hole in the light bar.

HYDRAULIC T OWER POWER UNIT
GENERAL START UP INSTRUCTIONS
NOTE: The ports are marked on the casing UP and DN. When facing the power unit with the motor up, plug the right hand, or DN port Jog the motor until the oil flows from the left hand, or up port. If oil does not flow from the UP port, reverse the wire leads on the motor, and re­peat. The pump is now primed. Connect the hose (or tubing) to the UP port and tighten. Connect the other hose end to the blind end of a fully retracted hydraulic cylinder. With the hose fitting loose, operate the power unit until oil (and no air) bleeds from the fitting. Tighten the fitting. Refill the reservoir.

TOWING AND STARTING INSTRUCTIONS
TOWING INSTRUCTIONS
Before towing the MAXI-LITE the trailer should be inspected visually to insure that the following operations have been completed.
1. Hitch is securely attached to towing vehicle (safety chains secure).
2. All outriggers and jacks are retracted and secured.
3. Tower is lowered.
4. Light xtures are positioned for transport.
5. Doors are closed and secure.
6. Check tires for adequate air pressure
7. Taillights are connected and operating (if equipped).
8. Ground rod is removed from ground and secured in the trailer
GROUND ROD INSTRUCTIONS (If so equipped)
1. Remove optional ground rod stowed just inside the left door (attached to the lower frame)
2. Unroll the electrical wire lead from the ground rod.
3. Attach the ground rod lead to the grounding lug located near the ballast compartment.
4. Drive the ground rod a minimum of 2 1/2 FT into the earth for adequate electrical grounding.
If this is not possible consult your local qualied electrician.
5. AFTER SHUTDOWN OF ENGINE: Remove the ground rod from the earth, remove lead from the trailer ground lug and store ground rod inside left door.
BEFORE STARTING
1. Fill the engine with the right grade of lubricating oil (see pg. 19) and to correct level (check
dipstick).
2. Ensure there is an adequate supply of fuel.
3. Ensure that the air cleaner is rmly attached, the air canister seals and the hose clamps
are properly sealed. Air cleaner element should be checked and replaced if necessary.
4. Install the ground rod.
DESCRIPTION OF OPERATION
By depressing the start assist switch, the fuel solenoid is energized. The solenoid plunger is drawn into the coil and activates the fue! control linkage to RUN position. When the engine starts, adequate engine oil pressure at the oil pressure switch will maintain the solenoid in the energized position. The start assist switch can be released as soon as the engine starts. A 10A inline fuse protects the solenoid from electrical damage.
LOW OIL PRESSURE SHUTOFF SYSTEM
Should a low oil pressure condition occur (less than 5 PSI), the pressure sending unit breaks the circuit between the battery and the fuel solenoid, allowing the spring load to immediately move the fuel control to the shutoff position.
HIGH COOLANT TEMPERATURE SHUTOFF SYSTEM
Should a high coolant temperature condition occur, the temperature sending unit breaks the cir­cuit between the battery and the fuel solenoid, allowing the spring load to immediately move the
fuel control to the shutoff position.

STARTING INSTRUCTIONS
STARTING THE ENGINE
NOTE: The Isuzu engine includes a glow plug cold start system controlled by the ignition switch on the control panel. Glow plugs are not needed on a warm engine or if the ambient temperature is above 50 F. Do not use starting uid or ether!
1. Turn the ignition switch to the PREHEAT position and hold until the glow plug lamp goes out.
2. Turn the ignition switch to the Start position until the engine starts. Release key as soon as the
engine starts.
3. If engine fails to start it may be necessary to cycle the glow plugs again.
NOTE: To prevent equipment damage, DO NOT hold ignition switch for more than 10 sec-
onds in the start position. If the engine does not start in 10 seconds, wait 30 seconds and
try the start sequence again. Do not run the cell motor for more than 20 seconds continu-
ously. Limit engine cranking to 3 attempts with a 2 minute cooi-down between each. After 3 attempts allow to cool to ambient temperature.
STOPPING THE ENGINE
1. Turn the ignition switch to the OFF position. This breaks the circuit between the battery and the fuel solenoid, allowing the spring load to immediately move the fuel control to the shutoff
position.
2. Disconnect the ground rod (if so equipped).
