NOTICE: When replacing the guide bar and chain, always use the specified bar and chain combination listed in this manual.
Disassembling the Worn Bar and Chain
a. Remove the battery, allow the saw to cool and tighten the oil tank cap.
b. Position the chainsaw on its side on a firm, flat surface, so that the side cover is facing upwards.
c. Rotate the side-cover knob counterclockwise one turn, then turn the chain-tensioning knob towards the
front handle as far as it will go to loosen the chain.
d. Rotate the side-cover knob counterclockwise, then remove the side cover. Clean the side cover with a dry cloth (Fig. 1).
e. Remove the bar and saw chain from the mounting surface. Remove the worn chain from the bar.
NOTICE: This is a good time to inspect the drive sprocket for excessive wear or damage.
Assembling the New Bar and Chain
a. Remove the battery, allow the saw to cool, and tighten the oil tank cap.
b. Lay the new saw chain in a loop on a flat surface and straighten any kinks. The cutters should face in the
direction of chain rotation, if they face backwards, turn the loop over. (Fig. 2 & 3).
c. Place the chain-drive links into the guide-bar groove. Position the chain so there is a loop at the back of
the guide bar (Fig. 4).
d. Place the loop around the sprocket of the power head.
NOTICE: 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.
e. Place the guide bar on the mounting surface by sliding the guide bar slot over the alignment flanges,
making sure that the tension-adjusting pin is inserted in the lower hole in the tail of the bar (Fig. 5).
f. Replace the side cover and lightly tighten the side cover knob by turning it clockwise. The bar must be
free to move for tension adjustment (Fig. 6).
NOTICE: To extend the guide bar life, invert the bar occasionally.
CAUTION
• The saw chain must be properly tensioned before using.
g. Remove all the slack from the chain by turning the chain-tensioning knob clockwise until the chain seats
snugly against the guide bar with the drive links in the guide bar groove.
h. Lift the tip of the guide bar up to check for sag (Fig. 7). Release the tip of the guide bar and turn the
chain-tensioning knob once clockwise. Repeat this process until the sag is eliminated.
i. Hold the tip of the guide bar up and tighten the side cover knob securely. The chain is correctly tensioned when
there is no sag on the underside of the guide bar and the chain is snug, but it can be turned by hand without binding.
NOTICE: If chain is too tight, it will not rotate. Loosen the side cover knob slightly and turn the tensioning
knob once to the "-" direction. Lift the tip of the guide bar up and retighten the side cover knob securely.
Assure that the chain will rotate without binding.
