Operation

4.9.3 Permissible depth of water

Note:

When driving your machine out of water, an

inclination of slope exceeding 15° would have

the rear of its upper turntable immersed in

water, thus the fan could be damaged due to

water.

Pay special attention to your machine when

driving it out of water.

CZ335-1103189

● Don not drive your machine into water

Fig. 4-74

where water level could reach the center of

carrier roller (1).

● Add grease to parts that have been soaked

long in water, till old grease is completely

squeezed out of the bearing (especially the

area around the pin of bucket).

● Never operate your machine in water un-

less the foundation of job site is strong

enough so that the level of water could not

1

CZ335-1103190

reach the center of carrier roller.

Fig. 4-75

● If the swing bearing, swing gear and cen-

tral swing joint are soaked in water, the

drain plug should be opened to remove

mud and water. Clean the swinging area

and reinstall the plug. Lubricate the mesh

gear and swing bearing inside the swing

unit.

4.10 Traveling on Slope

● When operating your machine on a slope,

never turn your machine or operate the

work equipment as that would cause your

machine to loose balance.

● It is dangerous to swing downward on a

slope when your bucket is loaded. If such

operation is necessary, you have to pile

Platform

up a platform on the slope with earth so

CZ335-1103191

that your machine could be kept on a level

ground.

Fig. 4-76

4-42

Operation

●

Never travel on a steep slope, which could

cause your machine to tip over.

●

The bucket must be lifted 20-30 cm above

the ground during traveling.

●

Never travel reversely down a slope.

●

Never turn your machine on a slope or tra-

verse a slope.

●

The above operations must be carried out

on a level ground. You might have to travel

a long distance for the sake of safety.

●

The operations must be performed in this

CZ335-1103192

way because the machine can be stopped

Fig. 4-77

safely at any time when it skids or be-

comes instable.

●

If the track shoes skid or the power of

tracks is unable to help your machine run

up a slope, never use the pulling force of

arm to run up the slope as that could dam-

age your machine.

1.

The travel control lever and fuel control dial

are used to keep your machine traveling at

a low speed when running down a steep

bucket.

When one of the tracks is trapped in the mud,

use the bucket to lift the track, place wood

planks or logs under the track and then drive

your machine out of the mud.

When both tracks are trapped in the mud and

the machine cannot move due to skidding, use

wood planks as described in the above meth-

od and cut your bucket into the ground in front

of your machine. Retract the arm as you do

in normal excavation, place the travel control

lever in "FORWARD" position, and drive your

machine out.

4.12 Recommended Applications

Besides the following applications, the scope

of application could be expanded by using

various additional attachments.

4.12.1 Backhoe operation

Backhoe operation is suitable for digging an

area which is lower than your machine.

90°

When your machine is in a state shown in the

right illustration (the angle between (bucket

90°

cylinder and link) and (bucket cylinder and

arm) is 90°), maximum digging force can be

obtained through the thrusting force of each

CZ335-1103197

hydraulic cylinder.

Fig.

4-82

When digging, using this angle effectively can

help you achieve the maximum working effi-

ciency.

4-45

Operation

The digging range of arm is from 30 to 45°, as

45°

30°

relative to the machine.

The angle may vary according to digging

depth, but it is better to keep it within the

above range if possible. Never operate the hy-

draulic cylinders to their full stokes.

CZ335-1103198

Fig. 4-83

4.12.2 Trench work

You can dig a trench efficiently by installing

a bucket suitable for this job and adjust your

tracks to parallel the to-be-dug trench line.

When digging a wider trench, excavate first

Parallel

both sides of the trench and then remove the

CZ335-1103199

middle part.

Fig. 4-84

4.12.3 Loading operation

In a place where the swinging angle is small,

working efficiency can be improved by parking

the dump truck at where the operator could

see easily.

It is more convenient to load more material if

the truck is loaded from rear rather than from

CZ335-1103200

its sides.

Operation

4.13 Parking Operation

Park your machine on a hard, level ground

that is free from dangers. If you have to park

your machine on a slope, chock the tracks

with blocks. You can also penetrate the bucket

120°

into ground as additional safety support.

If any of the control levers is moved unexpect-

edly, the machine may move suddenly and

CZ335-1103205

cause serious accidents. Make sure that the

hydraulic lockout control has been placed in

Fig. 4-86

"locked" position before you leave the cab.

1. Place both right and left travel control

1

levers (1) in neutral position to stop your

machine.

4.14 Checks after Each Workday

1. Inspect your machine and check the work

equipment, the exterior of machine, and

the undercarriage. Check for leaks of oil or

coolant. Repair it in case of any problem.

2. Refuel the tank to maximum level.

3. Check the engine compartment for any

paper or other debris. Remove them, if

any, in order to prevent fire.

4. Remove mud built up on the undercar-

riage.

5. If the ambient temperature is below -35°C,

make sure to drain the coolant of radiator

and engine (Sany uses the type of anti-

freeze liquid that freezes at -35°C. )

Operation

4.16.2 After each workday

CAUTION

Rotating track can cause severe injury.

Always keep a safe distance from rotating

track.

Observe the following precautions to prevent

the machine from being immobilized the next

day due to frozen mud and ice on the under-

carriage.

●

Remove all mud and water from your ma-

chine. Clean especially the piston rods of

hydraulic cylinders in order to prevent mud,

dirt or water from penetrating the cylinders

and spoiling the seals.

●

Park your machine on a hard, level ground.

Park your machine on planks if possible.

The planks can prevent your machine from

freezing with the ground and you can move

your machine the next day.

●

Open the drain valve to discharge accu-

mulated water of the fuel system so as to

prevent it from freezing.

●

Refill the fuel tank to the maximum level. In

this way, when ambient temperature drops,

the condensate in the tank could be mini-

mized.

●

After operation in water or mud, remove

the water on the undercarriage according

to the following instruction so as to extend

its service life.

1.

When the engine is running at idle speed,

swing the upper structure by 90° in order

to maintain the work equipment at the track

side.

2.

Lift one side of your machine just above

the ground, as shown in the illustration,

and run the track freely. Cycle this opera-

CZ335-1103210

tion between the left and right tracks.
