Maintenance

Owner’s Manual for MLT Light Tower

25

Section 4: Maintenance

Emissions Information

For warranty information, please refer to the diesel
engine manual supplied with this unit.

Daily Walk-Around Inspection

Perform a walk-around inspection of the unit every day
before starting the unit. Look for conditions that could
hinder performance or safety, such as (but not limited to):

Oil, coolant and fuel leakage

Blocked vents

Loose or missing hardware

Loose or broken electrical connections.

Inspect the fan belt for cracks, fraying, or stretching. Verify
the belt is properly seated in the pulley grooves. Replace
the belt according to the manufacturer’s recommendations.

General Maintenance

Poorly maintained equipment can become a safety
hazard. In order for the equipment to operate safely and
properly over a long period of time, periodic maintenance
and occasional repairs are necessary. 

DO NOT

 perform

routine service (oil and filter changes, cleaning, etc.)
unless all electrical components are shut off. 
Regular maintenance will improve performance and
extend engine/equipment life. Generac Mobile Products
LLC recommends that all maintenance work be
performed by a Generac Mobile Products Authorized
Service Dealer. Regular maintenance, replacement or
repair of the emissions control devices and systems may
be performed by any repair shop or person of the owner’s
choosing. However, to obtain emissions control warranty
service free of charge, the work must be performed by a
Generac Mobile Products Authorized Service Dealer or
authorized engine dealer depending on the repair. See
the emissions warranty.

Preparing for Service

Before servicing the unit, always follow the instructions
listed below.

1.

Verify the key switch is in the OFF position.

2.

Verify the circuit breakers are switched OFF (O).

3.

Disconnect the negative (–) terminal on the battery.

4.

Attach a “Do Not Start” sign to the control panel.
This will notify everyone that the unit is being
serviced and will reduce the chance of someone
inadvertently trying to start the unit.

Cleaning the Unit

Always clean the Light Tower after each use to remove
dust, grease, mud, or spilled fuel or oil. Use soft, clean
rags to wipe the cabinet exterior and control panel. Low-
pressure compressed air (less than 40 PSI [276 kPa])
can also be used to remove dust and debris from the
cabinet interior.
This unit contains sensitive electronic components that
can be damaged by high pressure and heat. Therefore:

Do not wash the unit with a high pressure hose or
power washer.

Do not wash the engine block or fuel tank with a
power washer or steam cleaner. Water may enter
the cabinet and collect in the generator windings or
other electrical parts, causing damage. 

Inspecting the Unit

If the unit is stored outside, check for water inside
the cabinet and generator before each use. If wet,
dry the unit thoroughly before starting.

Inspect condition of electrical cords. 

DO NOT

 use

the unit if insulation is cut or worn through.

Verify winch cables are in good condition and
centered on each pulley. 

DO NOT 

use a cable that

is kinked or starting to unravel.

Verify the safety pins for the mast lock rod and
mast lock bar are present and secured with a
chain. Check that the spring located in the mast
lock bar is not broken or missing. Check the
operation of the mast lock bar.

See 

Figure 4-1

. Verify correct mast cable routing.

Figure 4-1. Power Mast Cable Routing

Verify the wheel lugs are present and properly
tightened. Refer to

 

Towing Safety

.

CAUTION

inspection could result in damage to the unit.
