OPERATION
PRE-CUT CHECKLIST
•
Proper Chain Installation: The bumper should lead the segment into the cut.
•
Proper Chain Tension: The chain should be tight but easily pulled around the bar by hand.
•
Ensure all safety devices are properly mounted and functional and that all controls are in proper
working order.
•
Be sure there are no obstructions (plumbing, electrical conduit, air ducts) and no unnecessary people
present.
•
Always wear protective clothes, including hard hat, eye protection, hearing protection, non-slip safety
boots, gloves and avoid loose fitting clothes
•
Adequate Water Supply and Pressure:
Minimum Flow: 2 gpm (8 lpm)
Minimum Water Pressure: 20 psi (1.4 bar)
The single most important factor an operator can control to
increase chain life is to use adequate water pressure. Insufficient
water supply will result in excessive wear to the chain, which can
lead to loss of strength and chain breakage.
Note: Diamond chains with SealPro™ require a minimum water
pressure of 20 psi (1.4 bar).
PLANNING THE CUT
•
Select the proper chain type for the material being cut.
•
Outline the cut with a permanent marker for a visual cutting guide.
•
Avoid pinching the bar and chain. Always cut the bottom of an opening first, then top, and then the
sides. Save the easiest cut for last.
•
For the straightest cuts use the “Step Cut” method. First score the entire cut line approximately a
half-inch deep using the nose of the bar. Next deepen the cut by about two inches. Then plunge all
the way through and complete the cut using the Wallwalker®.
•
Be sure cut concrete cannot fall and injure operator or bystanders. Concrete is very heavy, one cubic
foot = 12”x12”x12” = 150 lbs. (30cm x 30cm x 30cm = 68kg).
•
Check for live electrical wiring near the cutting area or in the concrete to avoid electrocution.
