Chapter 4

OPERATING THE SAW

NOTE

Ensure the saw is properly set up and ready for operation in accordance with

Chapter 3 of this manual.

STANDARD CUTTING

WARNING!

Never stand directly in line with a spinning blade. Severe

injury could result if a segment breaks off or the blade

fractures.

1. Before starting any cut, make sure there is enough room to work without reaching

beyond your area of control. Ensure there is enough hydraulic and water hose

length to complete the cut without creating a safety hazard.

2. Start the cooling water flow to the blade.

3. With the saw blade above the cut, squeeze the trigger and allow the saw blade to

reach operating speed before the blade contacts the surface.

4. Pivot the saw on the front edge and slowly lower the blade into the cut line

approximately 2”–3”.

5. Run the saw along the cut line until the end of the cut.

6. At the end of the cut, pivot the saw on the front edge and raise the blade until it

clears the cut, then release the trigger.

7. Allow the blade to come to a stop before setting it down.

8. All cuts must be made in 2”-3” increments until the desired depth of cut is

attained.

•

If the cut runs lengthwise through a reinforcing bar, cut completely through it

in one pass to prevent the blade from deviating in the cut and jamming.

•

Attempting to cut too deep in one pass will result in a poor quality cut and may

cause the blade to jam.

9. When the final cut is complete, turn off the power unit and water supply, relieve

the pressure in the hoses, and disconnect the hoses from the saw. Wash down the

saw to remove all concrete slurry. Remove the blade and store everything in a

secure location.

CORRECTING A WANDERING CUT

1. If the cut starts to wander, stop sawing and correct the cut by plunging a straight

and deeper cut before and after the error.

2. After this go back with the blade, cutting twice the depth of the error, and cut

between the two new cuts using the blade to guide past the error.
