13. When moving the saw to a new location, be sure the blade is not
touching the ground. Always pay close attention to where you are
moving and where the blade is at all times.
E. Cutting Technique
Lower the blade into the concrete to the required depth by turning the hand
wheel clockwise.
Reduce the forward pressure if the saw begins to stall.
Note: For deeper cuts (4 inches or more), several cuts should be made in
incremental steps of 1-1/2 to 2 inches until the desired depth of cut is
reached.
Push the saw steadily forward using the front pointer as a guide. Exert
enough forward pressure so that the engine begins to labor, but does not
slow down. If the saw begins to stall, reduce the forward movement until full
rpm is restored to the blade. If the saw stalls, raise the blade out of the cut
before restarting. Avoid excessive side pressure or twisting of the blade in
the cut.
Additional Guide Lines For Sawing:
• Understand and follow all of the instructions in this owner’s manual.
• If wet cutting, turn on the water supply so that there is a minimum of 4-6
gallons per minute of water flow!!
• In critically hard aggregate, more than a single pass may be needed to cut
the desired depth.
• If the saw stalls in the cut, immediately stop the forward speed and raise
the blade out of the cut. If this is not done the belts can fail or the blade
may be damaged.
• Go slowly with a new blade until it opens up, that is, until the diamonds
can be seen and felt.
