OPERATION

PRE-CUT CHECKLIST

ADDITIONAL TENSIONING TIPS:

1. To reduce chain stretch and tensioning downtime, use 20 psi (1.5 bar) or

greater water pressure.

2. Oil the chain at the end of the day to prevent rust but be careful not to over

tension in this condition.

3. When pulling the chain around the bar by hand, be sure to wear gloves. The

bar rails can be very sharp. Grab only the diamond segments to pull the
chain.

4. Always pull the chain away from the WallWalker

®

. The point of the

WallWalker can also be very sharp.

PROPER CHAIN TENSION

Concrete cutting power cutters operate with looser chain tension than wood
chainsaws. It is common, especially on gas powered, concrete cutting
power cutters to have the drive links hang completely out of the bar. Concrete
cutting power cutters require water for cooling and flushing the cut. Rotating
the chain completely around the bar freely by hand will let you know you have
the chain properly tensioned.

Before tensioning chain, always turn the compressor off and relieve system
pressure before disconnecting from the compressor.

To maximize the life of the cutting system, ensure that proper chain

tension is maintained.

If tension is too tight, it will lead to excessive chain stretch, and a lot of the
power cutters power will be used to overcome friction. In severe cases the
chain may not turn at all and can lead to chain breakage. If the tension is set
too loose, the chain could be thrown off of the bar, or allow the sprocket to
turn with out turning the chain, which will damage the drive links.
