Homelite CSP4518 Adjusting The Chain Tension, Chain Maintenance, APPROXIMATELY 1.25 mm, UK - Page

MAINTENANCE

ADJUSTING THE CHAIN TENSION

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 nuts are loosened to finger
	tight and turn the chain tensioner clockwise to tension
	the chain.

APPROXIMATELY 1.25 mm

NOTE: A cold chain is correctly tensioned when there is

no slack on the underside of the guide bar, the chain is

snug and can be turned by hand without binding.

3. Re-tension 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 approximately1.25 mm

(1/8 in) out of the bar groove. To help determine the

correct warm chain tension, the tip of the combination

wrench can be used as a guide. See Figures 52, 53

and 54.

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 when cool. Check the “cold tension” before next use.

CHAIN MAINTENANCE

CAUTION:

Check that the switch is in the STOP “ / O ” position before working on the saw.

Use only a low-kick-back chain on this saw. This fast-cutting chain provides kick-back 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 increases the risk of a severe kick-back.
