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 chainsaws operate with looser chain tension than wood
chainsaws. It is common, especially on gas powered, concrete cutting
chainsaws to have the drive links hang completely out of the bar. Concrete
cutting chainsaws 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
saw’s 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.
