OPERATION
PRE-CUT CHECKLIST
• Proper Diamond Chain Tension: The diamond chain should be tight but easily pulled around the
guide 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).
• Always wear protective clothing, including hard hat, eye protection, hearing protection, non-slip
safety boots, gloves, and avoid wearing loose fitting clothing.
• Adequate Water Supply and Pressure:
Minumum flow: 2 gpm (8 l/min)
Minimum water pressure: 20 psi (1. bar)
Note: The single most important factor an operator can control to increase chain life is to
use adequate water pressure. Insuffecient water supply will result in excessive wear to
the chain, which can lead to loss of strength and chain breakage.
• Proper Hydraulic Supply to the saw:
Maximum Flow: 12 gpm (5 l/min) fixed flow
Maximum Hydraulic Pressure: 2,500 psi (172 bar)
PLANNING THE CUT
• Outline the cut with a permanent marker for a visual cutting guide.
• Avoid pinching the guide bar and diamond 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 guide 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. (0cm x 0cm x 0cm = 68kg).
• Check for live electrical wiring near the cutting area or in the concrete to avoid electrocution.
