Chainsaw Maintenance Guide
Maintenance of Chainsaw Trouble Shooting Chart
When a chainsaw stops working, it proves expensive with regard to its repair costs and lost production. For a secure, consistent and a hassle-free operation, it is vital that regular maintenance of the chainsaw is carried out in accordance with the manufacturer’s recommendations. Chainsaw maintenance calls for an expert approach and adhering to the following facts:
- The recommended servicing need to be accomplished at regular intervals.
- Need to perform a cautious scrutiny of all parts.
- Cleaning of the saw and connected equipment.
- Quickly addressing of the problems and faults found.
- When needed organizing for professional repairs.
In case, any components become faulty, mainly any safety devices, you must not operate the saw.
Chainsaws are available in petrol power for light trimming as well as heavy cutting. However, purchasing the right chainsaw for your precise use is of prime importance. Refer to our chain saw buying guide to identify your chain saw use.

Every Day Service (or Frequent Service as Needed)
Based on a regular daily engine operating time of 6 to 8 hours, the maintenance of chain saw is scheduled accordingly. However, the service duration may need to be reduced when you work mainly in dirty or dusty conditions, or when cutting dry timber. As per the manufacturer’s specifications, below tasks should be carried out on a daily basis:
- To stop the entry of foreign matter, apply the choke to shut off the carburettor throat, prior to removing the filter.
- To detect damage and infiltration of foreign matter, take out and check the filter.
- In case, the filter is damaged, replace it and clean as per manufacturer’s instruction.
- It’s highly suggested that a spare filter be kept so that it can be used as a replacement when need be.
Saw body, air intake vents and cooling fins must be carefully cleaned. In order to prevent damage to the paintwork and possible corrosion, you need to use plastic or wooden scrapers instead of metal screwdrivers.
Specifically, around brake band and operating mechanism, you must thoroughly clean. In order to keep the brake’s internal components free from amassing dirt and saw dust, repeated operation of the brake all through the day is necessary. Make sure of the right operation.

- Take outside cover, clean and inspect.
- To detect possible wear and cracks, you need to visually check chain and bar after removing the saw chain.
- Work from the nose backwards and clean out the groove. Remove burrs, if any.
- Oil holes need to be cleaned.
- Clean out wreckages.
- Make sure sprocket rotates and scrutiny for broken teeth.
- Grease, if suitable.
- To balance wear, reverse the guide (cutter) bar.
- Sharpen the chain after installing or install the spare chain.
- Several times during the day, it may be required to replace or sharpen the chain.
- Correctly tension the chain.
Loose Screws/ Nuts
- For stiffness, check screws/ nuts.
- Don’t tighten up more than required.
Ensure all safety devices are functioning properly.
Fill Fuel and Chain Oil Tanks
Reduce condensation of water in the tanks during storage by filling the tanks at the end of the day.
Refer to the owner’s handbook for other tasks that should be carried out on a normal basis in addition to the daily service items. This may include:
- For wear, inspect weekly.
- In case, wear marks on teeth exceed 0.5mm, change after two chains or sooner.
- When changing sprockets, always clean crankshaft stub and needle bearing, and lubricate bearing.
Take out, clean and scrutiny gap. Change as needed.
- Inspect filter.
- Fuel tank - With 2-stroke mix, flush out any amassed saw dust.
- To make sure effective operation, repeated lubrication of the pivot or sliding surfaces is required.
- Take to a competent chainsaw mechanic for chain brake fine-tuning.
Clean as required and inspect for maneuverability.
Clean fan and the cylinder fins after taking out fan housing.
For looseness and deterioration, examine springs/ rubber mountings.
- Take out and clean the spark arrester when the engine performance starts to decline.
- The spark arrester must be safely fixed always.
It is highly recommended to refer to a dealer/ service person for the most modern chainsaws that require a digital tachometer for tuning.
Within the first 20cm, the most common point of cord wear is. Examine the starter cord for possible rupture and change it if required, so as to avoid breaking up while on the job.
