3.Three dust intake port caps (D) Fig. 25, are supplied with the dust collector. NOTE: These caps should be

inserted into the intake ports as shown, when they are not in use. WARNING: DO NOT INSERT FINGERS

OR ANY FOREIGN OBJECT INTO THE DUST INTAKE PORTS WHEN UNIT IS OPERATING.

CONNECTING MACHINE TO POWER SOURCE

ELECTRICAL CONNECTIONS

A separate electrical circuit should be used for your tools. This circuit should not be less than #12 wire and should be protected with a 20 amp time lag fuse. Use proper extension cords. Make sure your extension cord is in good condition and is a 3-wire extension cord which has a 3-prong grounding type plug and a 3-hole receptacle which will accept the tool’s plug. When using an extension cord, be sure to use one heavy enough to carry the current of the tool. An undersized cord will cause a drop in line voltage, resulting in loss of power and overheating. Fig. 25A, shows the correct gauge to use depending on the cord length. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord. Have a certified electrician repair or replace damaged or worn cord immediately. Before connecting the motor to the power line, make certain the switch is in the “OFF” position and be sure that the electric current is of the same characteristics as stamped on the motor nameplate. All line connections should make good contact. Running on low voltage will damage the motor.

SINGLE PHASE

INSTALLATION

The motor rating of the Model 50-851 Dust Collector is 2 HP, 230 Volt, Single Phase. Before connecting your dust collector to an electrical power system, be sure the electrical system agrees with the motor rating of the tool.

The power cord is equipped with a plug that has two flat, current-carrying prongs in tandem and one round or “U” shaped, longer ground prong. This is used only with the proper mating 3-conductor grounding type receptacle as shown in Fig. 26.

When the 230 Volt three-prong plug on your machine is plugged into a grounded 3-conductor receptacle, the long ground prong on the plug contacts first so the machine is properly grounded before electricity reaches it.

WARNING: MAKE CERTAIN THE RECEPTACLE IN QUESTION IS PROPERLY GROUNDED. IF YOU ARE NOT SURE, HAVE A QUALIFIED ELECTRICIAN CHECK THE RECEPTACLE.
