The blade is spinning whenever the saw is running. Raise the blade as high as possible when ma-
neuvering so that the blade will not strike the pavement.
Dry cutting blades have been specially designed for use with concrete saws. Ensure that the blade
you are using is clearly marked for dry cutting.
When dry cutting, it is important to keep the air filter clean. Check the condition of the filter at least
every four (4) hours of operation. Clean the pre-filter (wash in soapy water and re-oil) and change the
paper filters as soon as it becomes clogged. Concrete dust is very abrasive and will quickly damage
internal engine parts, causing loss of compression and eventual engine failure.
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 1 inch (25 mm) or less, for the best results.
If reinforced abrasive blades are used for cured concrete, it is usually better to saw only 1 inch deep
per pass. If deeper cuts are required, cut in multiple passes.
Thinner Diamond Blades are especially advantageous when cutting dry.
MANEUVERING THE SAW
DrY CuttinG
Wet CuttinG
The water used on the blade is to provide coolant during cutting and to flush the concrete cutting from
the cut. Turn the water control to full “ON” when using wet cutting blades. The required flow rate is 5
to 8 gallons per minute.
Fnr HanDLe
The FNR handle moves the saw forward by pushing the lever away from the operator and moves the
saw in reverse by pulling the lever toward the operator. The further you push this lever, the faster the
saw travels.
WarninG
Before starting the engine, place this lever in neutraL.
The raise/lower handle controls the depth of the blade. When pulled back, the electric/hydraulic pump
will raise the blade out of the cut. When pushed forward the blade will lower. The lowering speed is
faster, the farther forward the lever is pressed.
