Adjusting The Chain Tension - POWER SMITH PCS140H Manual Del Operador

•
hold the chain in position on the bar and place the loop
around the sprocket.
•
Fit the bar flush against the mounting surface so that the
bar studs are in the long slot of the bar.
•
When placing the bar on the bar studs, ensure that the
adjusting pin is in the chain tension pin hole.
•
Replace the chain cover and lightly tighten the chain
cover locking knob by turning it clockwise. The bar must
be free to move for tension adjustment.
CAUTION:
The saw chain must be properly tensioned
before using.
•
Remove all slack from the chain by turning the chain
tensioning wheel clockwise until the chain seats snugly
against the bar with the drive links in the bar groove.
•
Release the tip of the guide bar and turn the chain
tensioning wheel 1/2 turn clockwise. Repeat this process
until sag does not exist.
•
Tighten the chain cover locking knob. The chain
is correctly tensioned when there is no sag on the
underside of the guide bar, the chain is snug, but it can
be turned by hand without binding.
NOTE:
If chain is too tight, it will not rotate. Loosen the
chain cover lock knob slightly and turn the chain tensioning
wheel 1/4 turn anti clockwise. Lift the tip of the guide bar
up and retighten the chain cover lock knob. Ensure that the
chain will rotate without binding.

ADJUSTING THE CHAIN TENSION

(FIG 32)
Warning:
remove the battery pack. 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. Failure to follow these instructions can
result in serious personal injury.
•
The more you use a chain the longer it becomes. It is
therefore important to adjust the chain regularly to take
up the slack.
•
Check the chain tension every time you refill with saw
chain oil. A new chain has a running-in period during
which you should check the tension more frequently.
Tension the chain as tightly as possible, but not so tight
that you cannot pull it round freely by hand.
•
Slide the chain cover lock knob lever out.
•
Turn the chain cover knob counter-clockwise to loosen the chain cover.
•
hold the knob and adjust the tension on the chain by turning the chain tension wheel clockwise for tighter tension
and counter-clockwise to loosen the tension.
•
Tighten the chain cover by turning the chain cover lock knob clockwise.
•
Slide the knob lever back in to lock the tensioning.
•
During normal saw operation, the temperature of the chain will increase. The drive links of a correctly tensioned
warm chain will hang approximately 0.050 in. (1.3 mm) out of the bar groove.
