MAINTENANCE

ADJUSTING THE CHAIN TENSION

See Figures 52, 53, and 54.

WARNING:

Never touch or adjust the chain while the motor is running. The saw chain is very sharp. Always wear protective gloves when performing maintenance on the chain.

1.Stop the engine before setting the chain tension.

2.Make sure the guide bar mounting nuts are loosened to finger tight, turn the chain tensioner clockwise to tension the chain.

Note: A cold chain is correctly tensioned when there is no slack on the underside of the guide bar, the chain is snug and it can be turned by hand without binding.

3.Retension the chain whenever the flats on the drive links hang out of the bar groove.

Note: During normal saw operation, the temperature of the chain increases. The drive links of a correctly tensioned warm chain will hang approximately .050 in. (1.25 mm) out of the bar groove. To help determine the correct warm chain tension, use the tip of the combina- tion wrench as a guide.

Note: New chain tends to stretch, check the chain tension frequently and tension as required.

CAUTION:

A chain tensioned while warm may be too tight upon cooling. Check the “cold tension” before next use.

CHAIN MAINTENANCE

See Figures 55 and 56.

CAUTION:

Check that the Ignition Switch is in the OFF “O” position before you work on the saw.

Use only a low-kickback chain on this saw. This fast-cutting chain provides kickback reduction when properly main- tained.

For smooth and fast cutting, maintain the chain properly.

The chain requires sharpening when the wood chips are small and powdery, the chain must be forced through the wood during cutting, or the chain cuts to one side. During maintenance of the chain, consider the following:

■Improper filing angle of the side plate can increase the risk of a severe kickback.
