CAUTION - Shut-down Saw for Cleaning

Whenever cleaning, adjusting or lubricating any part of the saw, MAKE CERTAIN to stop the engine and disconnect the spark plug wire from the spark plug.

The MP2 Saw gasoline model utilizes some of the same procedures that are used for the electric models. Please reference pages 20 and 21 for the below referenced procedures:

Conveyor Cart Placement

Blade Selection and Inspection

Saw Blades

Blade Installation

Assembly (Gasoline Powered Saws Only)

1.Remove the saw from its container and place it on a stable, level surface. Make sure location you choose can support the weight of the saw. The saw location should be rigid and stationary so that the saw will not move, sag, or sway due to the vibrations and movements of the saw.

2.The gasoline powered saw uses a mechanical water pump. This pump operates by drawing power from the drive V-belts, and has been adjusted dry cutting operation when shipped from the factory.

3.Fill the water tray with clean fresh water. The water pump intake (strainer) must always be fully covered by water to operate effectively. Also, keep the pump intake free of sludge, debris and other materials that may accumulate in the tray.

4.Make certain that the water hose will not come in contact with the blade or interfere with any moving parts. The best location for the water pump/strainer is between the splash shield and the rear of the water tray. This will prevent some of the abrasive particles from flowing through the pump.

CAUTION -Water Strainer Placement

ALWAYS position the strainer in the water tray in a manner that will allow the free movement of the conveyor cart, and clearance from the cutting blade and cutting action.

The mechanical water pump is

NOTEshipped from the factory for dry cutting applications.

Wet Cutting Setup (Gasoline Only)

To connect the mechanical water pump to the drive V- belts for Wet Cutting, perform the following:

1.Loosen the 2 hex head cap screws (Figure 12) that secure the pump mount bracket.

2.Push the pump handle downward to engage the pump. The drive belt should have approximately 1/8 to 3/16 inch belt deflection.

3.Tighten the 2 hex head cap screws that secure the pump mount bracket.

Figure 12. Pump Engage

4.With the engine running, squeeze the water pump priming bulb (Figure 13) until water begins to flow through the water lines.If the pump is working correctly, the cutting blade should be covered with a steady water mist. This will keep the blade cool while cutting.
