Proper Support for the Workpiece
•
Support the workpiece on in such a way that the
kerf will not pinch down on the blade.
•
Secure the workpiece so that it will not roll, slip
away or move due to vibration while cutting
•
The cutting sequence is important when making
cutouts. Always make the last cut in a way that
avoids the blade being pinched. Thus, make the bottom horizontal cut first, then the sides and finally
make the top horizontal cut last.
•
Make note of the weight of the workpiece and the direction which it will fall when it is cut through.
•
Whenever there is a situation where severing the workpiece will cause a hazardous situation, leave a tab
of material intact and finish off the operation with a chisel or the like.
Cutting Technique
•
Holding the machine with both hands to resist the start up torque, press the release button and then
squeeze the trigger switch.
•
Allow the machine to reach full speed before contacting the workpiece.
•
Adjust the water flow as needed by turning the water feed valve.
•
Then gently begin the cut with the rear portion of the blade until the kerf is established. Make the first
cut in the forward direction (so that you can see
the line of cut). Then make following cuts in the
backward direction.
•
Do not try to cut too much depth in one pass.
Never exceed about 50mm (2”) per pass.
•
It’s a good idea to first cut a shallow guiding
groove before proceeding to make the main
cut . If any correction is needed. Lift the blade
and cut slightly ahead and then back into the
existing kerf. Take care to avoid the blade being
pinched.
•
In round workpieces, the best technique is to
use a slow, uniform back and forth motion while
cutting with the bottom quadrant of the blade.
•
Do not allow the machine to bog down. Limit
your feed pressure to keep the blade spinning at
high speed.
•
Never side load the blade in the kerf.
•
Concrete cutting is very stressful for the motor: After the cut is finished, it is a good practice to run the
machine at no load for a short time to lower the motor temperature before stopping.
Stopping
Release the trigger to stop the machine. After the trigger is released, the blade will continue spinning for a
time.
