3.13 WORKING INSTRUCTIONS OPERATION G When working with the bucket in the longitudinal direction, the final drives should be in the rear position illust. (Z 0144), for the following reasons: The travel motors and travel gears are protected from fall- ing rocks etc. When the Shovel is operated on muddy ground and the tracks are covered with mud, the sprocket runs on a clean track when backing up. G When working with the loader in a cross direction to the track group, be sure that the track is not raised off the ground, illust. (Z 20978). This can cause the track to set-off from the rollers when it is lowered down on the ground.
Also the flanges of the track rollers and the track shoes can be bent by the excessive load. G Loading Trucks: Position the truck as closely as possible to the Shovel. Do not swing the attachment over unprotected driver cabs. Swing the attachment at a sufficient height over the loading platform Distribute material evenly on loading platform. Do not overload the truck. G Remove sticky material from the bucket. G Always keep the Shovel as close as possible to the work area. Short boom trips - high efficiency. G When turning into a pit, the rotating motion must not be stopped by the walls of the pit.
G Only a bucket with a complete set of teeth and cutting edges in good condition ensures efficient performance. G Loosen hard material and rocks with the bucket, not with the stick crowding thrust. G Correct bucket size and properly adjusted equipment pre- vents overloading and ensures maximum operating efficiency of the Shovel. 238
