During the first half to one hour of operation while the chain,
bar and sprocket are wearing in together, chain slack will
develope. Stop cutting every five to ten minutes and check
the chain tension. BE SURE TO SHUT OFF SAW. Always
reset tension when it is incorrect. TOO MUCH TENSION
creates excessive heat and wear, robs power and overloads
the engine. TOO LITTLE TENSION allows the chain to ham-
mer and chatter during operation, damaging the chain, bar
groove and sprocket ..
ADDITIONAL TENSJON CHECK: The chain should coast
slightly after throttling' down 'the
enqine ,
If
the chain stops
instantly, it is an indication that the chain is too tight.
NOtE': A loose 'chain is "normally caused by Stretch and
not a' loosecover nut.
