Keep the extension cord clear of the working area. Position the cord so that it will not come in contact with the drum or mixing materials while you are using the mixer. Failure to do so can result in serious personal injury.

WARNING:

Check extension cords before each use. If damaged replace immediately. Never use tool with a damaged cord since touching the damaged area could cause electrical shock resulting in serious injury.

ELECTRICAL CONNECTION

This tool is powered by a precision built electric motor. It should be connected to a power supply that is 120 V, AC only (normal household current), 60 Hz. Do not operate this tool on direct current (DC). A substantial voltage drop will cause a loss of power and the motor will overheat. If the tool does not operate when plugged into an outlet, double check the power supply.

GROUNDING INSTRUCTIONS

See Figure 1.

This product must be grounded. In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This tool is equipped with an electric cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances.

Do not modify the plug provided. If it will not fit the outlet, have the proper outlet installed by a qualified electrician.

WARNING:

Improper installation of the grounding plug is able to result in a risk of electric shock. When repair or replacement of the cord is required, do not connect the grounding wire to either flat blade terminal. The wire with insulation having an outer surface that is green with or without yellow stripes is the grounding wire.

Check with a qualified electrician or service personnel if the grounding instructions are not completely understood, or if in doubt as to whether the tool is properly grounded.

Repair or replace a damaged or worn cord immediately.

ELECTRICAL

This product is for use on a nominal 120 volt circuit and has a grounding plug similar to the plug illustrated in Figure 1. Only connect the product to an outlet having the same configuration as the plug. Do not use an adapter with this product.

Ground Fault Circuit Interrupter (GFCI) protection should be provided on the circuit(s) or outlet(s) to be used for the tool. Outlets are available having built-in GFCI protection and may be used for this measure of safety.

If the tool is used with an extension cord, ensure the connection of the tool's power cord and the extension cord are not on the ground. Auxiliary devices should always be plugged into the wall outlet and not at the connection of an extension cord and the power tools' power cord.

If a protected outlet is not available, do not use the tool until an outlet can be changed or auxiliary protection can be obtained. These auxiliary protection devices are available at your local retailer.

To avoid the possibility of the tool plug or outlet getting wet, position mixer to one side of a wall-mounted outlet to prevent water from dripping onto the outlet or plug. The operator should arrange a “drip loop” in the cord connecting the mixer to the outlet. The “drip loop” is that part of the cord below the level of the outlet or the connector if an extension cord is used, to prevent water traveling along the cord and coming in contact with the outlet.

If the plug or outlet does get wet, DO NOT unplug the cord. Disconnect the fuse or circuit breaker that supplies power to the tool then unplug and examine for the presence of water in the outlet.

WARNING:

To reduce the risk of electrocution, keep all connections dry and off the ground. Do not touch the plug with wet hands.

Use caution when working with fast hardening material such as quick set concrete. A few minutes of inactivity may be sufficient to allow the material to set. Setting times vary, refer to the material manufacturer's instructions.

NOTICE:

Routinely make a visual inspection of the mixer and the material being mixed. Do not let materials dry and harden inside the drum or on any part of the product. Failure to follow this warning could result in property damage or malfunction of the product.

■ Add and mix materials as described in the previous section.
■ Turn the mixer off.
■ Loosen the bolt on the back of the pivot bracket.
■ Carefully rotate the drum until it is pointing away from the frame (front and rear leg) and towards the work area.
■ Tighten the bolt at the rear of the pivot bracket to prevent the drum from rotating.

NOTICE:

Always keep the drum's opening in view when filling or emptying the concrete mixer. Certain mixing substances can harden quickly and could cause property damage or personal injury if spilled.

■ Unlock the drum.
■ Slowly lift the handles up to lower the drum opening.
■ Once the drum is empty or the job is complete, raise the drum opening and lock the drum in place.
■ Clean the mixer as described later.
