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 to the
chain.
1. Stop the engine before setting the chain
tension. Loosen the guide bar nuts slightly,
turn the chain tensioning screw clockwise to
tension the chain. Refer to Assembly-
Assembling the Bar and Chain Section.
Retighten guide bar nuts. A cold chain is
correctly tensioned when there is no slack on
the underside of the guide bar, the chain is
snug, but it can be turned by hand without
binding. For warm chain, see Item 3.
2. Chain must be retensioned whenever the
flats on the drive link tangs hang out of the
bar groove.
3. D u r i n g n o r m a l s a w o p e r a t i o n , t h e
temperature of the chain will increase. The
drive link tangs of a correctly tensioned warm
chain will hang approximately .050" (1.25
mm) 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.
CAUTION: Chain tensioned while warm,
may be too tight upon cooling. Check the
"cold tension" before next use.
C AUTION: A new chain has to be
retensioned more often than one that
has been in use for some time.
Breaking-in the Chain
New chains will stretch and must be tightened
frequently.
Lift the chain out of the bar groove and lubricate
the bar groove with additional oil. Place the chain
saw on a piece of cardboard or scrap plywood.
Start the chain saw (refer to the Operation-
Starting Engine Section) and allow it to run at
moderate speed for approximately one (1)
minute. Stop the engine. Check that the oil
pump is working properly. The cardboard should
have excess oil from the chain rotation if the oil
pump is working properly. Adjust the chain
