Operating Guide

MAINTENANCE

• Turn 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.

• Rotate the chain cover lock knob clockwise to secure. Retension the chain whenever the ats

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 1/16" (1.3 mm) 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.
