SERVICE SAFETY Do not use open pans of gasoline or diesel fuel for cleaning parts. Use good commercial, nonflam- mable solvents. Be sure you understand a service procedure be- fore you work on the Crawler. Provide adequate ventilation when charging bat- tery.
START ENGINE ONLY FROM THE OPERATOR’S SEAT! Avoid possible injury or death from Crawler run- away. Do not start Engine by shorting across starter so- lenoid terminals. Crawler may start and move if normal circuitry is bypassed. CAUTION: Never start Engine while standing on ground.

The following material is designed to familiarize you with the basic characteristics of a MAGNATRAC (tracked Vehicle). Its purpose is to teach you how a MAGNATRAC responds in comparison to the more familiar wheeled tractors. In addition, it outlines safe and efficient work procedures for a compact crawler tractor equipped with optional attachments (loaders, backhoes, blades, etc.)

BACKHOE OPERATION When lifting a full bucket, there is a tendency for the front of the tractor to rise. Counterweight in the form of a TERMINOLOGY ballast box is required to overcome this tendency. The backhoe should not exert more lift force than the effective BOOM counterweight can balance.

DUMPING THE BUCKET To dump the bucket at the end of the digging cycle, lift the bucket clear of the trench while crowding it out and swinging it to the spoil pile. As the pile is approached, dump the bucket. When the bucket is empty, the dipstick and bucket are in position to resume digging upon return to the trench.
