Assembling the Bar and Chain

DANGER

Contact with the chain saw teeth can cause serious
injury.

Remove the battery before performing any
adjustments or maintenance to the chain saw.

Always wear gloves when performing any
adjustments of maintenance to the chain saw.

If the bar and chain are not already installed, perform the following
steps:

1.

Place the chain saw on a level surface.

2.

Remove the two bolts that secure the cover (Figure 1).

Align the bar with the two studs and the adjusting pin.

5.

Place the chain around the drive sprocket, with the teeth of
the chain facing away from the sprocket (Figure 2).

6.

Feed the chain into the groove in the bar.

7.

Install the cover and the nuts, but do not fully tighten the
nuts.

8.

Hold up the tip of the bar (Figure 3).

Figure 3

9.

Tighten the chain by turning the tensioning bolt to the right
(Figure 2), until the chain touches the underside of the bar.

10.

Tigthen the 2 nuts (Figure 1).

11.

Check the chain tension. If more tensioning is required,
repeat this procedure starting at 7.

Note:

The chain tension is correct when you are able

to use a gloved hand to pull the chain smoothly around
the blade bar

Note:

A new chain may need adjusting after it’s first

use. Refer to Adjusting the Chain Tension (page 14).
