Chapter XII Troubleshooting

Section I General

To ensure excellent performance of Haihongexcavator, all components and parts are of high quality. Machine’s
performance and service life are determined not only by manufacturing quality and assembling quality, but also
maintenance quality.

The marketing representative and service engineer shall remind the user that preventive maintenance is the easiest
and most economical one among various ways of maintenance.

There are daily inspection and long-, medium- and short-term maintenance according to maintenance frequency.

Section II Troubleshooting of mechanism system

Symptom

Possible causes

How to solve

1.

The loose fasteners make noise.

1.

Inspect and tighten

Noisy structural components

2.

Aggravated

abrasion

between 2.

Adjust the clearance to less

bucket and end face of bucket rod

than 1mm

1.

Deformed spring and weakened

Bucket teeth have dropped

during operation

2.

elasticity of bucket tooth pin

Unmatched bucket tooth pin and

Change the bucket tooth pin

seat

1.

Loose crawler

1.

Tighten the crawler

2.

The guide wheel shall move
slowly in front on rugged road

The crawler has tangled up

2.

The driving wheel moves fast in

front on rugged road.

Section III Troubleshooting of hydraulic system

Symptom

Possible causes

How to solve

The whole excavator

does not move

Low oil level of hydraulic oil tank that the
main pump sucks no oil

Add enough hydraulic oil

Oil filter is blocked

Change the filter and clean the

system

Engine coupling is damaged (such as plastic
plate, elastic plate)

Change

The main pump is damaged

Change or repair the main pump

The servo system pressure is low or zero

Adjust to regular pressure. If it fails

to increase the pressure of servo

overflow valve, disassemble to wash;

if the spring is fatigue, add a washer

or change the spring.

The safety valve is set at low pressure or
stuck.

Adjust to regular pressure. If it fails

to increase the pressure, disassemble

and wash. If the spring is fatigued,

ass a washer or change the spring.

Oil suction pipe of main pump explodes or
comes off

Change with a new one
