Homelite UT43122, UT43102 Chain Maintenance, See Figures 36, RAKER DEPTH GAUGE CLEARANCE 025 in

MAINTENANCE

nStop the motor and disconnect from power supply before setting the chain tension.

nSlightly loosen the chain cover lock knob.

nTurn the chain tensioning knob 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.

nRotate the chain cover lock knob clockwise to secure.

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

NOTE:  During normal saw operation, the tem- perature of the chain increases. The drive links of a correctly tensioned warm chain will hang approximately .050 in. out of the bar groove.

NOTE:  New chains tend 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 36 - 37.

WARNING:

Before performing any maintenance, make sure the tool is unplugged from the power supply. Failure to comply could result in accidental starting and possible serious personal injury.

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

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:

nRaker (depth gauge) clearance.

•  Too low increases the potential for kick- back.

•  Not low enough decreases cutting ability.

nIf the cutter teeth hit hard objects such as nails and stones, or are abraded by mud or sand on the wood, have an authorized service center sharpen the chain.

NOTE:  Inspect the drive sprocket for wear or damage when replacing the chain. If signs of wear or damage are present in the areas indi- cated, have the drive sprocket replaced by an authorized service center.

NOTE:  If you do not fully understand the correct procedure for sharpening the chain after reading the instructions that follow, have the saw chain sharp- ened by an authorized service center or replace with a recommended low-kickback chain.
