0: PROTECTION OF CONTROLLER Always keep cover (1) of the display panel closed unless necessary. If rain or dust gets in, it may cause a failure in the controller. P: HOW TO ESCAPE FROM MUD 0 Always operate carefully to avoid getting stuck in mud. If the machine does get stuck in mud, use the following procedures to get the machine out. 1. When one side is stuck. When only one side is stuck in mud, use the bucket to raise the track, then lay boards or logs and drive the machine out. If necessary, put a board under the bucket also. * When using the boom or arm to raise the machine, always have the bot- tom of the bucket in contact with the ground.
(Never push with the teeth.) The angle between the boom and arm should be 90” to 110”. The same applies when using the inverting bucket. 2. When both sides are stuck. When the tracks on both sides are stuck in mud and the machine will not move, lay boards as explained in the diagram, and dig the bucket into the ground in front, Then pull in the arm as in normal digging operations and put the travel levers in the FORWARD position to pull the machine out. 3 Method of towing machine If the machine sinks in mud and cannot get out under its own power, or if the drawbar pull of the excavator is being used to tow a heavy object, use a wire rope (a) as shown in the diagram on the right.
t Do not use the hole for the towing hook. - 78 -
