1. Remove the battery, allow the pole saw to cool and tighten the oil tank cap.

2. Position the pole saw attachment on its side with the chain-sprocket cover is facing upwards.

3. Wear gloves. Using the dual-head wrench provided, loosen the cover screw to remove the screw and the chain-sprocket cover. Clean the chain-sprocket cover with a dry cloth and save it for reassembly (Fig. H).
   

4. Remove the bar and chain from the mounting surface. Remove the worn chain from the bar.

NOTICE: If there is difficulty in removing the bar and chain from the mounting surface, place the pole saw upright, with one hand support the bar, to loosen the chain tensioning screw counterclockwise with the other hand (Fig. I) and then remove the bar with the chain.

NOTICE: This is a good time to inspect the drive sprocket
for excessive wear or damage.

1. Lay the new saw chain in a loop on a flat surface and straighten any kinks (Fig. J).
   

 
2. 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. K).

Fig. K parts description see below:

• K-1 Chain Drive Links

• K-2 Guide-bar Groove

3. Hold the chain in position on the guide bar and place the loop around the sprocket of the pole saw.

NOTICE: Small directional arrows are engraved in the saw chain. Another directional arrow is molded into the tool body (Fig. L). 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 tool body. If they face in opposite directions, turn over the saw chain and guide bar assembly (Fig. M).

Fig. L parts description see below:

• L-1 Sprocket

• L-2 Tension-adjusting Pin

• L-3 Alignment Bulges

• L-4 Chain-tensioning Screw

• L-5 Guide-bar Slot

4. Place the guide bar on the mounting surface by sliding the guide bar slot over the alignment bulges, making sure that the tension adjusting pin is inserted in the lower hole in the tail of the bar (Fig. L).

NOTICE: If there is difficulty in inserting the tension adjusting pin into the hole, adjust the chain-tensioning screw properly until the tension adjusting pin is located exactly in the hole.

5. Replace the chain-sprocket cover and the cover screw. Slightly tighten them.

6. Remove all the slack from the chain by turning the chain-tensioning screw clockwise until the chain seats snugly against the guide bar with the drive links in the guide bar groove and lift the tip of the guide bar to check for sag. Release the tip of the guide bar and turn the chain-tensioning screw once clockwise. Repeat this process until the sag is eliminated (Fig. N).

7. Hold the tip of the guide bar up and tighten the chain-sprocket-cover screw securely.

NOTICE: To extend the guide bar life, invert the bar occasionally.

NOTICE: If chain is too tight, it will not rotate. Loosen the chain-sprocket-cover screw slightly and turn the tensioning screw 1/4 turn counterclockwise. Lift the tip of the guide bar and retighten the chain-sprocket-cover screw securely. Assure that the chain will rotate without binding.
