            How to maintain excavator


Any excavator is an expensive and valuable piece of equipment that needs careful care.An 

on-site outage means a loss of money.Downtime can be avoided by regular maintenance,

 and spending time and money on maintenance will help save money in the future.A routine 

maintenance routine can help avoid many problems that are time consuming and costly to fix.

Here are some Suggestions:

Check engine and hydraulic oil



These should be checked daily and added as

 needed.All machines are slightly different, so

 check your excavator manual for how often

 the oil needs to be changed.Contaminated 

oil can cause the hydraulic system to fail.

Use the right type of oil

This is not a place to try and save, and using low quality oil can cause a lot of problems.

High grade oils are specially formulated to prevent thermal and oxidative breakdown, 

as well as to improve soot related viscosity control and wear protection.Hydraulic systems

 are designed to exact tolerances, so the wrong oil or any other type of contamination 

often results in hydraulic failures.Cheaper oils often contain additives that will break when 

using a high load cycle.This is especially true for high-load boom operations, as the correct

 type and viscosity of the hydraulic oil is fundamental, as corrosion and wear 

resistant additives degrade at high temperatures.Conventional oil sample procedures 

are recommended and will show any contaminants.


Check water and fuel separator

Most modern excavators have a fuel filter, which has a water separator to separate

 the water from the fuel.These filters need to be checked daily and drained regularly.


The fuel

Just as the oil should be the correct type and of high quality, so should the fuel. 

For larger job sites it is common for a fuel technician to be contracted, who

 is responsible for delivering the correct fuel and ensuring cleanliness of the fuel

 and its delivery. A fuel technician will also make sure that the fuel contains the

 appropriate additives that prevent the growth of algae and other organisms. If 

you have hired a compact excavator for a smaller job, be sure to seek advice

 on the type of fuel and any additives needed. It is also important to remember 

to check the fuel tank vent, this can easily become clogged when working in

 dusty conditions, leading to over exertion on the fuel pump when delivering fuel.




Inspect the cooling system on a regular basis

The insulation and heat shield of the radiator in the engine room should be

 placed in the correct position.The heat exchanger must be kept clean.A coolant

 or oil leak can lead to a buildup of dust and debris, which slows air flow and, in

 turn, ACTS as an insulator to reduce heat exchange.The coolant must also be 

replaced as recommended by the manufacturer, as the coolant additive may stop

 working over time, leading to overheating and possible engine failure.


Well lubricated pivot points

All accessories must be lubricated regularly, using high quality grease.This should

 include boom, bucket, bucket, all pins and liners.Adequate lubrication is the key to

 prolong the service life of equipment, however, excessive lubrication will also cause

 environmental hazards and other problems.The accumulation of grease and oil on 

the machine can also cause a fire, not to mention getting dirty.

Checking the bucket and attachments

The bucket should be inspected on a daily basis during use, for cracks and wear. If the

 bucket is being used for heavy duty cutting work, the teeth will wear quickly. It is advisable

 to have a fresh set of teeth and keepers available. Other attachments should also be 

inspected for cracks and wear.



Track adjustment/track tension

If excavators are used in large quantities, this should be inspected daily.Too tight tracks can

 lead to premature wear and tear, and too loose tracks can lead to poor handling and eventually

 stall.A properly tuned track will maximize life and minimize wear on the track and its components.



Service the gearbox

Gearboxes require regular oil changes and maintenance, this is an area that is sometimes overlooked.



Check for leaks

All leaks must be corrected, to check for leaks monitor fluid levels, inspect the cooling system,

 the hydraulic system, the swing drive. If you suspect a leak anywhere, it must be immediately corrected.



General cleaning and maintenance

Excavator should be cleaned regularly, and external cleaning can be steam cleaning or 

high-pressure water.

The cabin should also be cleaned regularly.

Safety information must be visible at all times and cannot be obscured by dust and debris.

Steps and handles must be checked for safety to ensure they do not loosen or break.

Air recirculation filter elements must be cleaned regularly.If full of dust can shorten the life

 of air conditioning or cabin heaters, resulting in performance degradation.


We suggest you walk around and check your machine every day.Manufacturers and

 local dealers can provide training and necessary information on how to maintain your 

excavator as all models are slightly different from their own specifications.Some excavators

 have electronic screens that display maintenance alerts and programs that alert them to

 any potential problems, which help operators quickly identify and fix problems.Spending

 time on maintenance will help save money in the long run.
