WARNING

The engine's exhaust contains harmful emissions. ALWAYS ventilate the exhaust when operating inside tunnels, excavations or buildings. Direct exhaust away from nearby personnel.

Before starting the engine, make sure of the following:

The electrical load is disconnected and the main circuit breaker and all lamp (4) circuit breakers are switched to the OFF position.

CAUTION

NEVER start the engine with any circuit breakers in the ON position.

Light tower is placed on secure level ground with chock blocks underneath each wheel to prevent the light tower from rolling.

Outriggers have been fully extended to prevent the trailer from tipping.

Light tower trailer support stands have been positioned properly and the trailer is level.

Lamps have been adjusted to desired position.

Chocked blocks have been positioned under each wheel to prevent trailer from rolling.

Light tower trailer frame has been grounded correctly.

Lamps do not interfere with any overhead obstructions.

DANGER

ALWAYS make sure the area above light tower is open and clear of overhead power lines and other obstructions. The tower extends in excess of 30 ft. (9 meters). Contact with overhead power lines or other obstructions could result in equipment damage, serious injury or death!
