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 careful not to touch the bar with thumb or forefinger. 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.
5. Always turn the engine off before tensioning the chain.
ADDITIONAL INFORMATION
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. Wood
cutting chainsaws use oil to lubricate the chain. The oil makes the chain
very slippery and allows the drive links to fully nest between the teeth of
the drive sprocket. Concrete cutting chainsaws require water for cooling
and flushing the cut. Water is not as good as oil as a lubricant. Also, there
are concrete particles mixed in with the water. As a result, sometimes the
drive links do not nest properly on the drive sprocket. When this happens,
the chain acts like it got tighter. There seems to be tight spots and loose
spots as you pull the chain around the bar. If you tension when the chain
is in one of the loose spots, it will be too tight at some point in it’s rotation
around the bar. Rotating the chain completely around the bar by hand will
let you know you have the chain properly tensioned.
