INSTALLATION & TENSIONING
Following are the basic instructions for guidebar and diamond chain
installation and tensioning.
Never perform any maintenance or adjustments on the power cutter while
the hydraulic power source is connected.
Improper chain tension can lead to failure of the chain or derailing of the
chain off of the guidebar.
Check tension frequently and adjust if drive links of chain hang 18 mm (3/4 in)
or more below the guidebar groove
Always wear gloves when handling the bar and chain.
These components can develop sharp edges and cause cuts.
