6.2 SERVICING THE DIRECT DRIVE

MOTOR AND FAN (C190-C3000)

For motor maintenance, follow the manufacturer’s
directions. If your motor requires servicing under the
motor manufacturer’s warranty, contact an
authorized service center. Motors are greased at the
factory and do not need lubrication at time of
installation. However, regreasing may be necessary
after 1,000 hours of use. As a guideline, grease the
motor every 3,600 hours with high grade ball and
roller bearing grease. Recommended greases are
Shell Dolium R or Chevron SRI#2.

All bearings used are sealed, have been lubricated
at the factory and do not need lubrication at the time
of installation. Subsequent lubrication will be
required and the motor and bearing manufacturer’s
recommendations should be followed. Use the
following instructions as guidelines.

The fan bearings should be relubricated at six week
intervals when utilized for eight-hour workday
operations. The fan bearings should be relubricated
more frequently if operation time is longer than eight
hours per day. When lubricating, be sure to grease
both bearings and use high grade medium weight
ball bearing grease.

It is also recommended that you consult your
lubricant supplier regarding proper greases for both
the motor and fan bearings. Proper grease should be
based on hours of usage and environmental
conditions.

If any bearing operates roughly, the unit should be
shut down and the bearing replaced immediately.

Periodically inspect the fan blades to ensure proper
fan life. Clean the fan to remove any deposited
material if required.
