repOrting safety Defects  
If you believe that your vehicle has a defect that could cause a crash or could cause  
injury or death, you should immediately inform the National Highway Traffic Safety  
Administration (NHTSA) in addition to notifying Multiquip at 1-800-421-1244.  
If NHTSA receives similar complaints, it may open an investigation, and if it finds  
that a safety defect exists in a group of vehicles, it may order a recall and remedy  
campaign. However, NHTSA cannot become involved in individual problems  
between you, your dealer, or Multiquip.  
To contact NHTSA, you may either call the Vehicle Safety Hotline toll-free at 1-888-

sTaBILITY  
The Multiquip MLT25 Series Light Tower is a dedicated  
general purpose light tower engineered to provide  
dependable lighting for a wide range of applications. This  
includes lighting for construction sites, industrial locations,  
special events, and emergency conditions.  
The light tower can be raised vertically in excess of 31.5  
feet (9.6 meters) by means of a manual winch. The tower  
tensioning system is designed to provide the necessary  
tension to safely control the pivot of the tower. The light  
tower has a wind stability of up to 65 mph with outriggers  
and jackstands fully deployed.  
MeTaL HaLIDe LaMps  
The lighting system of the MLT25 Series Light Tower is  
comprised of 6 metal halide, 1000-watt lamps.These lamps  
provide maximum illumination with typical lighting coverage  
of 5 to 7 acres.The lamps are controlled by individual circuit  
breakers for versatility.  
paneL LIgHT  
A panel light automatically illuminates the control panel and  
all functions when the engine access door is opened.This  
feature is convenient for night deployment.  
engIne  
TRaILeR DesIgn  
The MLT25 Series Light Tower is powered by a diesel  
engine that is equipped with automatic shutdowns for  
low oil pressure, high coolant temperature, and alternator  
charge failure.  
The trailer design of the MLT25 Series light tower  
withstands the rigors of the jobsite in addition to providing  
smooth highway towing.

Figure 2. Major Components (Control Panel Side)  
Figure 2 and Figure 3 show the location of the controls and  
components for the MLT25 Series light tower.The function  
of each control is described below.  
6. Mast Cradle support — When towing of the light  
tower is required, place the tower mast into the cradle  
support. Make sure cradle lock/release pin has been  
inserted and mast is locked.  
1. Mast Rotation Locking Knob — Unscrew this knob  
to release mast for rotation. Tighten this knob to lock  
mast after it is set to the desired position.  
7. T-Bar — Allows the lamps to be mounted vertically or  
horizontally.  
2. Mast extension Winch — Use this winch to extend  
the mast to the desired height. Maximum height is  
approximately 31.5 feet (9.6 meters).  
8. Lamps — Six 1000-watt metal-halide bulbs with a  
110,000 lumens capacity each. Light coverage is  
typically between 5 to 7 acres.  
3. Mast Rotation Handles — Grip these handles to rotate  
mast to desired position.  
9. Cradle Lock/Release pin — Locks mast in cradle  
support and releases mast when removed.  
4. Lifting Bale — Light tower can be lifted using this lifting  
bale. The lifting bale is balanced for a fully configured  
light tower.Removal of any components will unbalance  
the lifting bale.  
10. Rear Jackstands There are two jackstands located  
at the rear of the trailer. Use these jackstands to level  
and support the light tower.  
11. Chock Blocks — Place these blocks (not included  
as part of the light tower package) under each trailer  
wheel to prevent rolling.  
5. Forklift pockets — Light tower can be lifted using  
these forklift pockets. Insert the forks of the forklift as  
far possible into the pockets.  
12. Outrigger Jacks — Use these 2 outrigger jacks to  
level and support the light tower.For more stability, the  
outriggers can be deployed.
