PRE-CUT Checklist, Planning the CUT

613GC OPERATOR’S MANUAL

OPERATION

PRE-CUT CHECKLIST

•Proper Diamond Chain Installation: The bumper should lead the segment into the cut.

•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) and no unnecessary people present.

•Always wear protective clothes, including hard hat, eye protection, hearing protection, non-slip safety boots, gloves, and avoid wearing loose fitting clothing.

•Diamond chains with SealPro® require a minimum water pressure of 20 psi (1.4 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. (30cm x 30cm x 30cm = 68kg).

•Check for live electrical wiring near the cutting area or in the concrete to avoid electrocution.
