Method For Escaping From Mud - Komatsu PW118MR-11 Operation & Maintenance Manual

MACHINE OPERATIONS AND CONTROLS
When ascending a slope, the bucket must always be upstream
of the tractor unit.
When operating on slope
• Never perform the swing operation on a slope by using the left work equipment control lever if the engine is
stopped. Otherwise, the upper structure will swing under its own weight.
• Do not open or close the slide door while traveling or operating the machine on a slope. The operating force
may vary suddenly.
Always keep the door locked in place.
• Pay close attention when opening or closing the sliding door while the machine is idle. The door opens or
closes suddenly under its own weight, and it is dangerous.
• Before working on a slope or traveling on a rough ground, check DEF tank and add sufficient amount of
DEF as necessary. If the remaining DEF level becomes low, sudden drop of its level or abnormality in urea
SCR system may be detected. If DEF level caution lamp or DEF system caution lamp lights up in red, move
the machine to a level place immediately and add DEF.

METHOD FOR ESCAPING FROM MUD

get the machine out.
