the saw and put the chain around the sprocket. Align the sprocket teeth with the chain.

11. Make sure the adjustment pin is in the adjustment

pin hole of the guide bar. (Fig. 70) Note: An adjustment pin and screw are used to adjust the tension of the chain. It is very important when you assemble the guide bar that the adjustment pin is engaged in the adjustment pin hole on the guide bar.

12. Attach the sprocket cover (A), washer (B) and

sprocket cover nut (C). Lightly tighten the nut with your fingers. (Fig. 71)

13. Adjust the chain tension. See

To adjust the chain tension on page 20

Note: Examine the chain tension regularly. A chain that has the correct tension has better performance and longer life. To adjust the chain tension

Put on the gloves before you adjust the chain tension. The chain is sharp and can cause injuries to you. Note: The chain extends during the operation, specially when you operate for the first 15 minutes. You must examine and adjust the chain tension frequently after you use or refuel the product.

1. Examine the chain and guide bar for any damage.

Replace any part that is damaged.

3. Use your fingers to tighten the nut against the cover.

4. Turn the adjustment screw clockwise until the saw

chain touches the bottom of the guide bar, then turn the adjustment screw clockwise an additional ¼ turn. (Fig. 72)

5. Use the screwdriver end of the combination tool to

move the chain around the guide bar. The chain must move smoothly and freely. (Fig. 73)

6. If the chain does not move, it is too tight. Loosen the

sprocket cover nut and turn the adjustment screw counterclockwise ¼ turn. Tighten the sprocket cover nut.

7. Make sure there is not a gap between the chain and

the bottom of the guide bar. If there is a gap, the chain is too loose and further adjustment is needed. Do not operate the product if the chain is loose.

8. When the chain has the correct tension, lift the end

of the guide bar and firmly tighten the sprocket cover nut clockwise with the combination tool. (Fig. 74) (Fig. 75) Note: The chain has the correct tension when it moves freely around the guide bar, but it does not hang below the guide bar. To sharpen the chain

WARNING: Put on the gloves before you

sharpen the chain. Sharpen the chain from inner side of the cutter to the outer side.

WARNING: Sharpen on the forward stroke

only. Use 2 or 3 strokes for each cutting edge. Sharpen sufficiently to remove damage to the cutting edges, which include the side plates and the top plates of the cutters. Keep all cutters at the same length. Sharpen the chain when:

• The wood pieces decrease in size.

• The saw cuts to one side or at an angle.

• You must push the saw through branches with force.
