613GC OPERATOR’S MANUAL

SET-UP

GUIDE BAR AND DIAMOND CHAIN INSTALLATION

Note 1: Be aware that the guide bar rails may develop sharp edges over time so always pull the diamond

chain by the diamond segments.

Note 2: Do not “over tension” the diamond chain. Loss of power will result. It is normal for the drivelinks to

hang underneath the guide bar. The diamond chain should be tight but be able to be pulled around the

guide bar by hand.

Note 3: To prevent chain tensioner breakage, be sure the side cover nuts are tightened to approximately

20 ft-lbs (27Nm).

STEP 7

Manually pull the chain across the top of the

guide bar away from the Wallwalker®. It is

normal for the chain hanging under the guide

bar to alternately tighten and loosen as the

chain rotates. See Note 1.

STEP 8

Hold the guide bar nose up and tension the

chain. The chain should be tight but able to be

pulled around the guide bar by hand.

See Note 2

STEP 9

Continue to lift up on the nose of the guide bar

and firmly tighten the side cover nuts.

See Note 3.

STEP 6

Install side cover and thread the side cover

nuts on finger tight.
