Drilling Tools Inspection and maintenance guidance for DTH hammers, drill bits, drill rods, couplings and other drilling consumables.
Air-Treatment Equipment Support for air dryers, filtration systems, drainage components and other compressed-air treatment equipment.
Preventive Maintenance Maintenance recommendations may be reviewed according to equipment model, operating hours and working conditions.
Spare Parts & Consumables Required maintenance parts, replacement components and consumables can be identified together with the maintenance request.

Start With the Right Information

A fault code alone may not explain the complete cause of an equipment problem.

Operating pressure, temperature, abnormal noise, maintenance history, environmental conditions and recent component replacement can all affect troubleshooting.

Fault Diagnosis

Identify issues and analyze possible causes.

Operating Guidance

Provide guidance for safe and efficient operation.

Maintenance Support

Recommend maintenance items and service intervals.

Spare-Part Identification

Help identify correct parts and confirm compatibility.

Installation Guidance

Offer installation recommendations and best practices.

Technical Documentation

Provide manuals, diagrams and technical information when available.

How Our Troubleshooting Process Works

A structured troubleshooting process helps reduce unnecessary part replacement and improves communication between operators and technical personnel.

Submit Equipment Details

Send the equipment model, serial number, nameplate, fault information and a description of the problem.

Provide Photos, Videos or Operating Data

Photos, controller displays, videos and operating parameters can help our technical team understand the equipment condition.

Technical Review

The available information is reviewed together with the equipment configuration, operating condition and maintenance history.

Recommended Checks

We may recommend inspection steps, operating checks, maintenance actions or further information required for diagnosis.

Repair or Parts Recommendation

When a component requires replacement, suitable spare parts or maintenance items can be identified according to the equipment information.

Follow-Up Support

Additional technical guidance may be provided as troubleshooting or maintenance work progresses.

Know the Hazards

Troubleshooting industrial equipment may involve rotating machinery, electrical systems, hydraulic pressure, compressed air, hot surfaces and other hazards.

Stop & Isolate

Stop the equipment when required and follow applicable lockout, isolation and stored-pressure release procedures before inspection or maintenance.

Use Qualified Personnel

Electrical, hydraulic, pressure-bearing or other safety-critical work should be carried out by trained and qualified personnel.

Pressure & Heat Safety

  • Release stored pressure where appropriate
  • Allow hot components to cool
  • Do not open pressure-bearing systems while energized

PPE & Site Procedures

  • Use suitable personal protective equipment
  • Follow the equipment manual
  • Follow applicable site safety procedures

Stop Before Restarting

If continued operation may cause injury or serious equipment damage, stop the machine and arrange inspection by qualified personnel before restarting.

Maintenance & Troubleshooting FAQ

How often should Kaishan equipment be maintained?

Maintenance intervals depend on the equipment model, operating hours, application and working environment. Refer to the applicable maintenance documentation and provide the equipment model when requesting specific guidance.

What information should I provide for troubleshooting?

Provide the equipment model, serial number, nameplate photo, fault code, problem description, operating hours and clear photos or videos of the issue.

Can you diagnose equipment problems remotely?

Many common operating and maintenance issues can be reviewed remotely using equipment information, operating data, fault codes, photos and videos. Complex problems may require an on-site inspection.

Can you help identify the required replacement part?

Yes. Provide the equipment model, serial number, original part number if available and clear photos. Dimensions and installation-position photos can also help when the part number is unavailable.

Can you recommend maintenance parts?

Maintenance items can be reviewed according to the equipment model, operating hours and service requirements.

Do you provide installation or repair guidance?

Remote guidance may be available for suitable maintenance and replacement procedures. Complex mechanical, electrical, hydraulic or safety-related work should be completed by qualified personnel.

What should I do if the machine has a serious fault?

Stop operation if continued use may create a safety risk or cause serious equipment damage. Record the fault information and arrange inspection by qualified technical personnel before restarting.

For faster troubleshooting: provide the equipment model, serial number, nameplate photo, fault code, operating hours and clear photos or videos when submitting your request.
