Fig.12

6.   Slide the guide bar slot over the alignment 

flanges until the tension adjusting pin is 

inserted in the lower hole in the tail of the 

bar.

NOTE: 

Small directional arrows are engraved 

in the saw chain. Another directional arrow is 

molded into the housing. When looping the 

saw chain onto the sprocket, make sure that 

the direction of the arrows on the saw chain will 

correspond to the direction of the arrow on the 

housing. If they face in opposite directions, turn 

over the saw chain and guide bar assembly.

7.   Replace the side cover and slightly tighten 

the side cover knob.(Fig. 13)

Fig.13

8.   Lift the tip of the guide bar up to check for 

sag. Release the tip of the guide bar and 

turn the chain tensioning knob clockwise. 

Repeat this process until the sag is 

eliminated.

9.   Tighten the side cover knob securely to 

ensure that the saw chain is properly 

tensioned before using.

NOTE: 

If chain is too tight, it will not rotate. 

Loosen the side cover knob slightly and turn the 

tensioning knob once from right to left. Lift the tip 

of the guide bar up and retighten the side cover 

knob securely. Assure that the chain will rotate 

without binding.

Adjusting the chain tension

-   Stop the motor and remove the battery pack 

before adjusting the chain tension. Make 

sure the side cover knob is loosened. Turn 

the chain tensioning knob clockwise to 

tension the chain. (Fig. 14)

Fig.14

-   A cold chain is correctly tensioned when 

there is no slack on the underside of the 

guide bar and the chain is snug, but it can 

be turned by hand without binding. The 

chain must be re-tensioned whenever the 

flats on the drive links do not sit in the bar 

groove.

-   During normal saw operation, the 

temperature of the chain will increase. The 

drive links of a correctly tensioned warm 

chain will hang approximately 0.08" (2 mm) 

out of the bar groove (Fig. 15).
