GENERAL INSPECTION

Prior to each use, the light tower should be cleaned and inspected. Check for loose, missing, or damaged nuts, bolts or other fasteners.

generator/ENGINE MAINTENANCE

Refer to the accompanying DCA25SSIU3 Operator and Parts Manual (Part Number 49810) for information on how to maintain the generator and engine.

Check Cable Wear

The wire rope (cable) that raises and extends the mast is a very important part of the light tower. There is one cable/ hand winch system, located on the tongue of the trailer, that raises and extends the light tower mast. There is a second cable/hand winch system located on the mast that serves to raise and lower the two extendable sections of the mast.

DANGER

Wire rope (cable) will fail if it is worn, frayed, misused, crushed, kinked or damaged in any way. Always check the cables and pulleys for any abnormalities before use.

Do not use it if there is even the slightest cause for concern and replace any damaged cables or pulleys immediately.

Servicing the Mast Raise/Lower Cable System

To replace any components in the mast raise/lower cable system, use the following steps (See Figure 12):

HAND WINCH

CABLE

MAST

PULLEY

CABLE SHEAVE

Figure 12. Mast Raise/Lower Cable System

1.Lower the mast to the horizontal resting position.

2.Inspect the cable clamps, pulleys, and other components for worn or damaged parts.

3.Disconnect the cable from the ball socket pin and remove from the mast pulley and cable sheave. Detach the cable from the hand winch as necessary.

4.Replace the pulley and the cable as needed.

5.Rethread the cable through the pulley and reattach the cable to the ball socket pin.

6.Raise and lower the mast several times to verify correct operation.
