Towinga trailer requires care! Both thetrailer and vehicle must bein good condition and securelyfas-
tened to each other to reduce the possibility of an accident. Also, some states require that large trailers
beregistered and licensed. Contact your localDepartment of Transportation office tocheck on license
requirementsforyourparticularunit.
•Check that the hitch and coupling on the towing vehicle are rated equal to, or greater than, the trailer's
"grossvehicleweightrating"(GVWR).
• Checktiresontrailerfortreadwear,inflation,andcondition.
•Inspectthehitch andcouplingforwearor damage. DO NOT towtrailerusing defectiveparts!
•Make sure the trailer hitch and the coupling are compatible. Make sure the coupling is securely
fastenedtothevehicle.
•Connect safety chains in a crossing pattern under the tongue and attach the breakaway cable TO
THE REAR BUMPER OF THE TOWING VEHICLE. Do not attach the cable to the trailer hitch.
•Makesuredirectionalandbrakelightson the trailer are connected and working properly.
•Check that all lug nuts holding wheels on are tight and that none are missing.
•Maximumrecommendedspeedforhighwaytowingis45m.p.h. Recommendedoff-roadtowingspeed
is not to exceed 10 m.p.h. or less depending on terrain.
Whentowing,maintainextra space between vehicles and avoid soft shoulders, curbs andsuddenlane
changes. Ifyou have not pulleda trailer before, practiceturning, stopping, and backingup in an area
awayfromheavy traffic.
A film of grease on the coupler will extend coupler life and eliminate squeaking. Wipe the coupler clean
and apply fresh grease each time the trailer is towed.

1. Remove the mast cradle locking pin from the mast cradle (I).
2. Check both sets of mast cables for excessive wear or damage. Make sure the cables are properly centered in
each pulley (J). Check the electrical cord for damage.
3. Make sure the area behind the unit is clear before
raising the mast to the vertical position.
4. Remove the safety pin (K) from the mast lock bar
(L). Using the handle for the lower mast winch (M),
raise the mast until it is vertical and the tab on the
mast is positioned into the mast lock. The mast lock
bar should snap into place automatically. Secure
the lock with the safety pin (N).
5. After the mast is up and locked into place, use
the upper mast winch (O) to telescope the
tower to the desired height. Extend the mast slowly,
making sure that the electrical cord is extending
at the top sections of the mast. If, for any reason,
the winch cable begins to develop slack or any of
the tower sections get stuck, STOP IMMEDIATELY
andcontact anauthorizedservicecenter.
6. The mast can be rotated by loosening the locking
knob at the bottom of the mast (Q). Turn the mast
until the lights face in the desired direction and
then tighten the knob.
The trailer must be leveled with the outriggers extended before raising the tower. The outriggers
must remain extended while the tower is up. Failure to level the trailer or extend the outriggers
will severely reduce the stability of the unit and could allow the tower to tip and fall.
WARNING
Do not start the unit if the insulation on the electrical cord is cut or worn through.
Bare wires in contact with the mast or frame may energize the trailer and cause electrocution.
Repair or replace cord.

NOTICE
Do not crank the engine longer than 10 seconds at a time. If the engine will not start, wait 30 seconds to
allow the starter motor to cool and then repeat the starting procedure. Excessive cranking will cause
damage to the starter.
5. Note: If oil pressure is not obtained within 30 seconds after the key is switched to the RUN position, the low-oil
automatic shutdown will turn off the fuel supply, stopping the engine. Check the oil level and turn the key to the
OFF position to reset the oil pressure timer before attempting to restart the engine.
6. Oncetheengineisrunning,allow it to reach normal operatingtemperaturebefore switching on any loads.
AUTOMATIC SHUTDOWN
This unit is equipped with a low oil pressure and high coolant temperature auto-shutdown system. This system will
automatically shut off the fuel supply to stop the engine if oil pressure drops too low or the engine exceeds normal
operating temperature. Return the switch to the OFF position to reset the unit after you have determined the cause
oftheshutdown.
ENGINE STARTING AND OPERATION
Do not start the unit if the insulation on the electrical cord is cut or worn through.
Bare wires in contact with the mast or frame may energize the trailer and cause electrocution.
Repair or replace cord.
WARNING
NEVER START THE ENGINE WITH ANYOF THE
CIRCUIT BREAKERS SWITCHED ON! Any load on
the generator during start up will cause severe
damage or destroy the generator!

1. Oncetheengine is up to temperature and running smoothly,
switch main circuit breaker (1) to the ON “I” position.
2. With main circuit breaker on, switch each individual circuit
breaker for the lights (2) to ON “I”, one at a time.
3. The ballast indicator lights (3) will come on momentarily as the
lights strike. As the lights warm up, the ballast indicator lights
will continue to get brighter and then remain on. This confirms
thatpower is coming from the ballasts to the lights.
4. If an indicator light does not come on, the ballast may need to
be serviced. If the indicator light comes on and stays lit but
the related light is not illuminated, check the bulb or the mast
wiring.
5. The lights require a warm up period of 5-15 minutes before they reach full output. If the lights are shutdown, they
requireacool-downperiod of approximately 10 minutes before they can beswitchedonagain.
6. The light tower uses four 1000W bulbs. When checking or replacing the bulbs, wipe them with a clean cloth to
avoid leaving any grease, oil residue or fingerprints on the glass. Any residue can create a hot spot on the bulb,
causingprematurebulbfailure.
AUXILIARY OUTLETS
Thecontrolpanel is equipped with two outlets forrunningaccesso-
ries or tools from the generator. Power is supplied to the outlets
any time the engine is running and the main circuit breaker is
switched ON “I”. Note: Do not pull more than 1000W from each
outletwhenthelights are on. This will overload the generator and
cause the main circuit breaker to trip. Should the breaker trip,
switch off the lights, remove some of the load to the outlets and
wait 10 minutes for the bulbs to cool before turning them back on.
With all of the lights off, the full generator output may be used with
the optional 240V twist-lock outlet.
VOLTAGE REGULATION (OPTIONAL)
Someunitsmaybeequipped with an electronic voltageregulator. This voltageregulatorcontrolstheoutput of the
generatorbyregulatingthecurrentintothe exciter field. The regulator has three screwdriver adjustable potentiom-
etersthatmay be adjusted for voltage, stability and underfrequency(U/F). Ifequipped, the voltage regulator on your
unitisadjusted before shipment from the factory. ContactMagnumProductsLLC foradditionalinformationbefore
attemptingtoadjustthevoltageregulator.
Bulbs become extremely hot in use! Allow bulb fixture to cool 10-15 minutes before handling.
WARNING
NEVER OPERATE THE LIGHTS WITHOUT THE PROTECTIVE LENS COVER OR WITHALENS
COVER THAT IS CRACKED OR DAMAGED! The bulbs in the light fixtures produce high
temperatures and operate under pressure. A broken or missing lens cover could cause the
bulbs to shatter, causing injury.

DERATING FOR ALTITUDE
Alllight towers are subject to deratingforaltitude and temperature. Although derating shouldnotaffecttheoperation
of the lights, it will reduce the available power for operating tools and accessories connected to the auxiliary outlets.
Typical reductions in performance are 2-4% for every1000ft.(305 m) of elevation and1%per10ºF(3-5º C) increase
inambientairtemperatureover 72º F (22.2º C).
SHUTTING DOWN
Whenyou have finished using the lighttowerproceed with shut down as follows:
1. Removeanyloadsfromtheauxiliaryoutlets.
2. Switchtheindividualcircuitbreakersforeach

4. Release the mast lock by pulling the safety pin on the mast lock and pulling the lock free. Turn the handle of
the lower mast winch until the mast spring begins to pivot the tower down. Release the mast lock and continue
to lower the tower until it rests in the cradle. Note: If the mast lock does not pull free, operate lower winch
slightly to relieve pressure on the mast lock.
5. After the mast is completely down, insert the cradle lock pin and secure it with the safety pin.
6. Position lights to aim at the ground. If the trailer is going to be moved,
MagnumProductsLLC strongly recommends that the lights be removed
from the mast and stowed for transportation. On units equipped with quick
disconnect fittings for the lights, disconnect the power cords from the
junction box at the top of the mast. Replace the dust caps on the junction
box. On other units, remove the junction box cover on the top of the mast
anddisconnect the wires from theterminalblocks by flipping the leverdown
on the block and pulling the wire free. Remove only the wires that are
connected to the mast lights. Note: Consult the wiring diagrams on page
24 for the proper locations when connecting the mast light wiring to the
terminal blocks.
