INSTALLATION

UNPACKING

Immediately after unpacking the mixer, check for possible shipping damage. If this machine is found to be damaged after unpacking, save the packaging material and contact the carrier within 15 days of delivery.

LOCATION

Prior to installation, test the electrical service to assure that it agrees with the specifications on the machine data plate.

Place the mixer in its operating location. There should be adequate space around the mixer for the user to operate the controls and to install and remove bowls. The area above and to the right side of the mixer should allow the top and side covers to be removed for routine maintenance and servicing.

Once in position, the mixer must be leveled:

• Remove the two top cover screws and the top cover.

• Place a level on the top rim of the large pulley (Fig. 1). Slide shims under the base contact surface of the mixer as required to level it front-to-back and side-to-side.

• Do not replace the top cover until installation is completed.
