7.0Assembly

The sander should be placed on a level, sturdy floor, preferably concrete, with plenty of space surrounding it for on- and off-loading of stock, and general maintenance work.

Open the two lower side panels and use the leveling screws inside the cabinet (Figure 1) to level the sander. The machine can also be secured to the floor with high quality lag screws (not provided) through the four mounting holes inside the cabinet.

Remove the protective coating from exposed metal surfaces with a soft cloth moistened with kerosene or a good commercial solvent. Do not use acetone, gasoline or lacquer thinner, as these have a low flash point and can be a fire hazard, as well as damage the paint finish. Do not get solvents on rubber or plastic areas of the machine.

7.1Air Supply Connection

The sander must be connected to an air supply unit. The recommended working pressure is 75 to 80 PSI.

The air connection is on the Filter/Regulator unit located at the back of the sander (Figure 2). Attach the incoming air supply to the connector with a flexible hose.

The working pressure can be adjusted with the pressure regulator. Lift up on the adjustment knob and rotate it clockwise to increase air pressure, counterclockwise to decrease air pressure. When the desired pressure is shown on the pressure gauge, push down the adjustment knob to lock the setting.

7.2Dust Collection

Connect a dust collection system (not provided) to the dust ports atop the sander cabinet with 5” flexible hose and hose clamps. Make sure your dust collector has sufficient capacity for this machine.

Always turn on the dust collector prior to operating the sander.
