4. Lower blade into cut slowly.
5. Cut as fast as blade will allow. If blade misaligns from cut, reduce forward speed or
depth of cut.
6. Use only enough side pressure on saw handles to follow cutting line.
2.9 Cutting
Lower the blade into concrete to the required depth by turning the tilt crank counter-
clockwise. Ease the saw slowly forward. Slow forward pressure if the saw begins to stall.
Note: For deeper cuts (4 inches/102mm or more), several cuts should be made in incre-
mental steps of 1-1/2 inch (38mm) to 2 inches (51mm) until the desired depth is reached.
Push the saw steadily forward using the front pointer as a guide. Exert enough forward
pressure so that the engine/motor begins to labor, but does not slow down. If the saw
begins to stall, slow forward movement until full RPM is restored to the blade. If saw
stalls, raise the blade out of the cut before restarting. Avoid excessive side pressure or
twisting of the blade in the cut.
2.10 Belts & Pulleys
Never adjust the V-belts and pulleys when engine is running.
1. The best tension for a v-belt drive is the lowest tension at which the belts will not slip
under full load.
2. Increase tension until the belts are snug in the grooves. Run the drive for about five (5)
minutes to “seat” the belts. Impose the peak load. If the belts slip, tighten them until
they no longer slip at peak load. Most new belts will need additional tensioning aer
seating.
3. Remember, too much tension shortens belt and bearing life.
4. Check the belt tension frequently during the first day of operation. Check the belt
tension periodically thereaer and make any necessary adjustments.
5. The two most common causes of sheave misalignment are:
a) The engine drive sha and the blade sha are not parallel.
b) The pulleys are not located properly on the shas.
