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.
