Operation
Saw only as deep as the specifications and job conditions require.
Remember, airflow helps to cool the blade during dry cutting.
Cutting too deep with one pass, or exerting excessive forward or
side pressure can be dangerous. Step cut in increments of 2 inches
(50 mm) or less, for the best results.
If reinforced abrasive blades are used for cured concrete it is usually
better to saw only 1 deep per pass. If deeper cuts are required, cut in
multiple passes.
Thinner Diamond Blades are especially advantageous when cutting
dry.
5.8 Aligning the Saw with a Marked Line
Refer to the figure below. Push the saw forward and approach the
marked line at an angle. Stop when the distance from the rear edge
of the saw frame to the line (distance A) and the distance from the
pointer to the line (distance B) are approximately equal. Lift the rear
wheels slightly off the ground by lifting on the handles and swing the
rear of the saw around until the pointer is on the line and the saw
frame is parallel to it. Do not tilt the saw too far forward to keep the
blade from contacting the concrete. The saw should now be aligned
with the marked line. Practice will fine tune this method. Critical to
this method of alignment is to ensure that the saw pointer is properly
aligned (see alignment procedures).
5. Starting a Cut
With the engine running at half-throttle, open the water valve to
full open. Check to verify that the water is flowing fully. Adjust the
amount of water flowing on the blade to a desired amount.
After adjusting the flow of water increase to proper throttle setting.
Lower the blade into the cut by slowly turning clockwise on the
depth control wheel. If the water supply is interrupted,
stop cutting
immediately.
When the desired depth of cut is reached, lock the control wheel in
position with the depth control locking knob. During cutting, do not
exert excessive side pressure on the handle bars to attempt to steer
the saw. Use only enough pressure to follow the original marked line.
