In order to protect the electric parts in
cabin, close top window and cabin door when
you park the excavator.
In cold weather, the excavator should be
parked on hard ground to avoid crawler and
ground congealing together. If congealment
happens accidentally, please lift crawler
by using boom, move excavator carefully to
avoid damaging drive wheels.
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
keep low noise running, try your best not to run at maximum accelerograph, the best revs of
engine should be 1600-1800 r/min.
13) Before every shift, according to the rules, inject grease to all reaming connections through
grease nozzles until the grease overflows. Otherwise it will cause axle and sleeves damage.
3.5.5 Park excavator
1) Place excavator on a horizontal ground.
2) Lower the bucket to ground.
3) Place accelerograph handle on minimum
load position for 5 minutes.
4) Turn ignition key to “OFF” position, and take out key.
5) Pull pilot control lever to lock position.
6) Lock all doors and compartments.
7) Inspection after the engine is stop.
z Check the oil tank and water tank, work
device, superstructure and infrastructure,
repair all the abnormal parts;
z Fill all the oil tank, this can refer to
chapter “check the oil level”, and clean
all the paper scrapes and dirt from engine.
