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.
