Pre ‐ cut checklist 4.4

Ensure proper chain tension: The chain should be 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, etc.) and no unnecessary people
present.

Always wear protective clothing, including hard hat, eye protection, hearing protection, non ‐ slip safety
boots, gloves. Avoid wearing loose fitting clothing.
Planning the cut 4.5

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
12 mm (1/2 in) deep using the nose of the guide bar. Next, deepen the cut by about 50 mm (2 in). Then
plunge all the way through and complete the cut using the WallWalker®.
Warning!
-
Be sure cut concrete cannot fall and injure operator or bystanders.
Concrete is very heavy, one cubic foot = 30 cm x 30 cm x 30 cm = 68 kg
(12 in x 12 in x 12 in = 150 lbs).
-
Check for live electrical wiring near the cutting area or in the concrete to
avoid electrocution.
