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 be more oecumenical.
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,
Attention in excavation
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 6 m away
from working radius. When begin to work or transport with full load, operator should ring
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.
5) During work, do your best to avoid pulling the handle to the end, otherwise it will make
hydraulic oil overheated and damage components.
6) Slewing is not allowed if bucket has not left the working face.
7) It allows using arm and bucket to impel or level off rideau, but never operate side of bucket
to work by slewing force.
8) When work at swampy ground (especially on rainy day), the excavator must be kept at a
proper distance away from working face to prevent collapse.
9) After stopping machine, shut off all switches of control panel, shut off electric power and
lock cabin.
10) During digging work, avoid overload work to reduce energy consumption and hydraulic oil
temperature.
11) During digging work, pay attention to the cylinder stroke end, avoid using baffle of boom,
arm, and bucket to prolong the lifetime of framework.
12) If the productivity can satisfy the working demand, in order to prolong engine lifetime and
