Select the desired travel speed by operating the travel speed control switch.
Make sure that the position of the upper structure and of the undercarriage is known before you move the machine. The drive sprockets should be at the rear of the machine.Note: The directional steering controls will operate normally if the drive sprockets are at the rear of the machine and the idlers are at the front of the machine and under the cab. When the sprockets are under the cab, the travel controls will operate backward.
Turn the engine speed dial in order to increase the engine speed (rpm) to the desired speed.
Push both travel levers forward at the same time in order to travel forward. If both travel levers are pushed farther, the travel speed at the selected engine speed (rpm) will be faster.Note: If the machine does not operate or if the machine does not travel in a straight line, consult your Caterpillar dealer.

Note: The following information applies to CJM1-UP,; DAP1-UP,; KDG1-UP, ; PEH1-UP,; AZP1-UP and ; SCR1-UP.Note: If the engine is operated at low idle or at low load for 24 or more consecutive hours, the engine should be run at rated conditions for five to fifteen minutes. Running the engine at rated conditions should clean out the catalytic converter/muffler.
The muffler and converter will become extremly hot during engine operation. A hot muffler and converter can cause serious burns. Allow adaquate cooling time before working on or near the muffler and converter.
Proper operation, driving techniques and maintenance are key factors in obtaining the maximum service life of the muffler and converter. Some precautions should be taken if the engine is equipped with a muffler and converter.Avoid excess idling. Excessive idling can cause the muffler and converter to plug. A plugged muffler and converter will lead to an increase in exhaust back pressure. Operating the engine in extremely cold conditions can cause the muffler and converter to plug sooner.
