Bar and Chain Removal and Assembly
1. Place the power unit on a flat, stable work surface with
the muffler facing to your right.
2. Pull back (toward the forward handle) on the chain brake
lever to ensure that the chain brake is disengaged.
3. Using the “Scwrench” multi-tool, loosen and remove the
bar nuts securing the clutch cover to the power unit. Set
the clutch cover aside. Tip: If working in the field, place the
bar nuts in the clutch cover to keep from losing them in
grass or foliage.
4. Install the guide bar on the bar studs, and slide the bar
back until it comes into contact with the drive sprocket.
5. Protective gloves should be used when handling the
chain. Carefully remove the saw chain from its package.
Stretch the chain out into a long horizontal loop. The
cutting teeth on the top length of chain should face
away from the power unit. The cutting teeth on the
bottom length of the chain should face toward the power
unit.
6. Wrap the chain around the drive sprocket first, and lay
the drive links of the chain into the groove along the
outer perimeter of the guide bar. Lay the chain over the
nose (tip) of the guide bar.
7. Slide the bar forward until the bar mates with the
tensioning tab. Make sure that the drive links of the
chain are seated within the groove around the perimeter
of the bar. If the bar will not slide forward far enough, use
the screwdriver end of the Scwrench to turn the tension
screw counter-clockwise. The tension screw is located on
the front of the power unit, next to the guide bar.
WARNING
FAILURE TO PROPERLY TENSION THE CHAIN
COULD RESULT IN DAMAGE TO THE UNIT OR
SEVERE INJURY OR DEATH. OVER TENSIONING
COULD CAUSE DAMAGE TO THE SAW’S POWER
UNIT OR GUIDE BAR. LACK OF TENSION COULD
CAUSE THE CHAIN TO DISENGAGE THE BAR
COMPLETELY, ALLOWING IT TO WHIP BACK
WHERE IT COULD CONTACT THE OPERATOR
CAUSING SEVERE INJURY OR DEATH.
NOTE: Make sure the chain brake is OFF.
8. Replace the clutch cover over the bar, and turn the bar
nuts onto the bar studs. Only finger tighten the bar nuts at
this step.
9. Locate the tension screw on the front of the power unit
next to the guide bar. Use the Scwrench to turn the
tension screw clockwise. This will take the slack out of
the saw chain. When properly tensioned, two conditions
must be met:
•
The chain should not hang or droop away from the
guide bar.
•
You should be able to pull the chain slightly away from
the guide bar, but not so far as to be able to disengage
the drive links from the groove around the perimeter of
the bar.
10. Pull up on the guide bar’s nose and use the Scwrench to
tighten the bar nuts. Check that the chain spins freely
around the bar by hand. If there is resistance, the chain
may be too tight.
11. Place the bar scabbard over the guide bar and saw chain.
This guard will help to protect the user from the sharp
cutting teeth as well as help keep the cutting teeth sharp
when the saw is not in use.
12. Check the tension of the saw chain frequently during
use, especially during the first two hours of use on a new
chain. Re-tension as needed.
13. Always release the tension in the chain after finishing
work and before the saw chain and guide bar cool
completely. As the saw chain heats up during operation,
it will expand and stretch, requiring re-tensioning on
occasion. As the saw cools down the saw chain will
shrink, and if left tensioned, could cause severe and
permanent damage to the guide bar or the power unit’s
drive components.
