42 IMPORTANT INFORMATION ON EXCAVATOR OPERATION If the water or mud level reaches higher than the top of the tracks, the swivel bearing, swivel motor gear and ring gear may be exposed to mud, water and other foreign objects. The excavator must be properly pressure washed after each use. Do not try to crush concrete or boulders using side swings with the bucket. Also avoid using side sweeps of the bucket to move earth piles. Under all circumstances avoid the following operations: Thoroughly clean the area around the swivel bearing, swivel motor gear and ring gear to remove foreign objects. Excavation using the gravitational impact of the machine.
Inspect the swivel motor oil sump (if equipped) for water contamination. If water is present, refer to operator's manual for lubricant replacement procedure. Compacting of gravel or soil using the dropping action of the bucket. Excavation using the travelling power of the machine. Do not try to drop or shake off soil adhering to the bucket in the manner given in the points below. This can cause damage to the machine. Adhered soil can be shaken off when the bucket is being emptied by moving the bucket out to the maximum stroke of the cylinder. Should this not suffi ce, swing out the arm as far as possible and operate the bucket back and forth. Do not hit the dozer with the boom cylinder!
Make sure that the boom cylinder does not hit the dozer when doing deep excavation. If necessary swing around so that the dozer is in the back of the machine. Pay attention when pulling in the bucket! When pulling in the bucket (for driving or transportation) avoid hitting the dozer. Avoid collisions! When moving the excavator, pay attention that the dozer does not collide with obstructions such as boulders etc.. Such collisions shorten the life of the dozer and the cylinder substantially. Support the machine correctly! When stabilizing the machine with the dozer, Iower the dozer to engage the full width on the ground.
Refer to operator's manual for proper swivel bearing, swivel motor gear and ring gear lubrication procedures. Reinstall any protective covering if removed earier.
