660GC OPERATOR’S MANUAL
14
PRE-CUT CHECKLIST
• Proper Diamond Chain Tension: The diamond chain should be tight but easily pulled around the
guidebar 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 are present.
• Always wear protective clothing, including hard hat, eye protection, hearing protection, non-slip
safety boots, gloves, and avoid wearing loose fitting clothing.
PLANNING THE CUT
• Outline the cut with a permanent marker for a visual cutting guide.
• Avoid pinching the guidebar 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 guidebar. 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.
OPERATION
IMPORTANT
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, and/or damage to the
guidebar nose sprocket.
