xx). Do not force the blade in to the cut!! Step Cutting provides the best performance (fastest cut and longest blade life). Never saw deeper than 4” per pass as deeper passes will shorten the blade life and places higher stresses on the saw. Never twist, rotate, or bend the blade while in the cut. Do not attempt to cut in a circle or arc as the blade may be damaged.
Step Cutting
1.Follow general instructions outlined in the section D. Operating the Saw pages 9 to 20.
2.When deep sawing (more than 4”) or concrete with hard aggregate, sawing to full depth in several cuts should be made in incremental steps of
3.Gradually move the speed control lever forward to increase the cutting speed. If the blade stalls in the cut (which can happen when deep sawing) immediately raise blade from cut using the button on the top of the speed control lever. If not done at once, the belts will spin freely and burn. Check belts for proper tension and continue sawing at a slower rate of speed.
4.On final pass, lower the blade until it hits the
It is common, on the final pass of the cut, for pavement to wedge blade, particularly on a hot day. When this happens, immediately stop engine. If the blade is wedged, remove the Blade Shaft Bolt and Outside Collar and move the saw away from the blade. To remove a wedged blade from the concrete, use a jack hammer and carefully chip out concrete around the blade. (Pounding or twisting the blade may cause severe damage).
6.Go slowly with a new blade until it "opens up" that is, until you can see and feel the diamonds.
7.If saw leads off excessively, adjustment can be made on the left side of the rear axle (see section F. Lead Off Adjustment on page 26 of this manual). Small corrections can be made by leaning on handles.
8.Deep sawing is very hard on saws and blades. Experienced operators soon get a "feel" for the saw and are constantly on guard to slow down when they hit excessive steel or hard aggregate.
