INITIAL INSPECTION
1. Upon receipt of your Brawn Mixer, check for possible
shipping damage. Report any damage immediately
to the carrier and to Brawn Mixer.
2. All Brawn Mixers are shipped with the shaft and
impeller(s) disassembled from the drive assembly.
In addition, the clamp or cup mount and any
mounting hardware for portable mixers are shipped
loose.
3. Storage: Mixers should not be stored near vibrating
machinery to avoid damage to the bearings. Store
mixers as packaged by the factory. For longer
storage periods, consult factory. If electric motors
have been subjected to humid conditions, check the
insulation resistance between phase and mass and
between the different phases. The resistance should
not be less than 100 megohms. If the resistance is
less, please consult the factory. If mixer is stored for
more than a year, the condition of the gear lubricant
should be checked before the mixer is put in
operation (see lubrication instructions).

Inadequately or improperly tightened hardware can
loosen, due to vibration during mixer operation. This can
result in reduced mixer life or damage to equipment.

average torque values should be considered only as a
guide and not as absolute values.
