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.
