of the frame base.
2. Adjust the orientation of the rear pointer rod and
retighten the screw and nut to secure.
Concrete Cutting
WARNING
 DO NOT expose yourself or anyone
else to the direct line of the blade
when operating the saw.
 The direct work area should not contain buried
or embedded electrical, gas, or water lines that
could be damaged and/or cause personal
injury while cutting.
Note: Always raise the blade to provide proper clearance
between the blade and the ground when maneuvering
the saw.
Helpful Hints Prior to Cutting
Keep the following in mind for better efficiency while
cutting:
 Use just enough handle pressure to guide the saw
down the cutting line. DO NOT forcibly direct (twist)
the saw from side to side when cutting. DO NOT
jam, cock, or wedge the blade in a cut.
 Moving too quickly when cutting may stall the saw,
or may cause the blade to climb out from the cut. If
the saw stalls while cutting, put the saw in neutral
and raise the blade from the cut to restart the
engine.
 Avoid sawing excessively deep to preserve the
blade and reduce sawing costs.
 DO NOT lower the blade too quickly or move the
saw forward too quickly when finishing a partial-cut
to avoid forcing the blade into the concrete.
 Always have a proper water flow when cutting for
maximum blade efficiency. Using too much water
when cutting will make the slurry look clear. Not
using enough water will make the slurry look thick
and pasty.
 Refer to the Diamond Products’ Guide for
Professional Concrete Cutters for additional cutting
tips and information.
Tasks Prior to Cutting
Complete the following tasks prior to cutting:
 Align the cutting guide(s) with the blade.
 Clearly mark the cutting line.
 Turn off all electricity, gas, and water around the
direct work area.
Making a Cut
1. Align the blade and cutting guide(s) with the cut line.
2. If the saw is equipped with a clutch (optional), turn
on the Blade Clutch switch with engine at idle to
start the blade rotation.
3. Turn on the water and adjust the water flow.
4. Lower the blade to just above the cutting surface
and set the cutting depth indicator at zero (ref. fig.
15).

Indicator
5. Turn on the Auto Water switch if desired for
automatic water on/off when cutting. Note: When the
cutting depth indicator enters the Auto Water On/Off
Zone the water will turn on/off automatically and will
not require the water flow to be reset every time the
blade is lowered back into the cut. If the auto water
feature is functioning in reverse (water goes off
when blade is lowered into cut), rotate depth
indicator 360 degrees to reset.
6. Slowly lower the blade into the surface at the start of
the cut line for the initial cut. Make the initial pass
across the entire cutting line using the most effective
travel speed. If the blade is coming up out of the cut,
decrease travel speed and/or feed depth. DO NOT
CUT FULL DEPTH IN ONE PASS. Always use the
step-cut method when cutting for maximum
efficiency. For example, when cutting to a depth of
ten inches, begin with a two-inch deep maximum
initial pass, then a four-inch deep pass, and finish
with another four-inch deep pass to complete the
cut.
7. Raise the blade out of the cut and reposition the saw
at the start of the cut line. DO NOT move backwards
with the blade in a previous cut.
