OPERATION & MAINTENANCE MANUAL SWE18UF

 Do not allow operation on rocks (neither hard rocks nor soft ones).
 Do not allow breaking or flat operation by slewing the machine. (e.g. break wall
or flat the ground).
 Do not allow digging the bucket teeth into ground while slewing.
 Do not allow pulling the machine forward by digging bucket teeth into ground.
 Do not allow excavation by walloping or using the weight of the machine.
 Break the hard groundsill rocks into small pieces by hydraulic hammer before
excavation, etc. This can prevent damage to machine and will save cost
comparatively.
 During excavation, especially deep digging work, pay attention to avoid bucket teeth
and boom cylinder colliding with dozer blade.
 Try your best to place the dozer blade at the rear end.
 The dozer is used for simple bulldozing work, so never dig the dozer blade too deep,
or the dozer blade or even the infrastructure may be damaged.

4.5.2 Composite Movements of Excavator
1) When the machine slews, you can operate the composite
movement of boom and bucket.
2) It can operate as follows: bucket digs while extending or
retracting arm; arm digs while lowering boom, etc.
3) Besides the co-operation between right and left joystick,
pull either of the joysticks to any diagonal orientation (45
direction), can achieve the adjacent two composite
movements.
4.5.3 Upper-Structure Slewing Brake
Release slewing control handle, return it to neutral position, it will bring sufficient brake power to brake the
platform. While reversing the handle operation can bring more brake torque.
4.5.4 Excavation Keypoints
1) Operator must wear safety helmet and work clothes, make sure the safety of working area before starting
machine.
2) During digging work, the dozer blade should be placed on ground.
3) Other people are not permitted to stand on the machine or within the range of 6m away from working
radius. When begin to work or transport with full load, operator should honk the horn to warn.
4) Bucket should dig along the cutting track and avoid digging hard earth constrainedly, otherwise it will
cause the hydraulic oil overheated.
