Governor Control Lever
To prevent engine damage, the governor must be out of slow range when operating hydraulic controls.
Slow (1.) - Move the lever to this position to decrease the engine speed. Economy (2.) - Move the lever to the detent position for lower fuel consumption and quieter operation. Fast (3.) - Move the lever to the right and rear, beyond the detent position, to increase the engine speed. Use this position for maximum production work.Directional Travel Pedals
The farther the pedals are pushed down, the faster the travel speed.The brakes are applied automatically when the travel pedals are released. Reverse Direction Travel Pedal (1.) - Push down on the left pedal for reverse travel. The machine will always travel toward the sprockets. Forward Direction Travel Pedal (2.) - Push down on the right pedal for forward travel. The machine will always travel toward the idlers.Steering Control
The travel pedals must be used with the steering control lever to allow machine movement. Spot Left Turn (1.) - Move the lever all the way to the left to reverse the left track, allowing a quick left turn (counter rotation). Pivot Left Turn (2.) - Move the lever part way to the left to stop the left track, allowing the machine to turn gradually. Straight (3.) - Move the lever to this position to allow the machine to go straight in either direction. Pivot Right Turn (4.) - Move the lever part way to the right to stop the right track, allowing the machine to turn gradually. Spot Right Turn (5.) - Move the lever all the way to the right to reverse the right track, allowing a quick right turn (counter rotation).Hydraulic and Directional Lock Lever
Locked - Push the lever down and all hydraulic controls and the travel pedals are inoperable. Unlocked - Pull the lever up and all hydraulic controls and the travel pedals are operable.Swing Lock Pin
Engage the pin only when the upper structure is aligned with the track to avoid machine damage.Do not attempt to engage the pin when the upper structure is rotating.
Engaged - Push the lever down and forward to lock the upper structure to the lower structure and prevent rotation. Disengaged - Pull the lever up and back to unlock the upper from the lower structure and allow rotation.Swing Brake Control
Apply - Pull the lever up over center, to prevent movement of the upper structure that could be caused by swinging load. Release - Lower the lever to release the swing brake.Turn the knob on the end of the lever, to adjust the brake. It should require a firm pull to apply the brake. The brake should prevent swing movement against swing motor torque when properly adjusted. Turn the knob to the right to tighten the brake, or to the left to loosen the brake.If the brake cannot be adjusted, consult your Caterpillar dealer.
