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:

Air Filter

• 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.

Cleaning

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.

Sprocket Nose:

• Clean out wreckages.
• Make sure sprocket rotates and scrutiny for broken teeth.

• 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.
