9-1-1 Description
All Cumberland 40 Series machines are equipped with
rotor bearings that are prelubricated and sealed for life and
therefore require no further lubrication.
9-1-2 Screw Jack Lubrication Instructions
Lifting screws should be checked periodically to ensure that
they are adequately lubricated. It is recommended that the
screw jack be lubricated at monthly intervals, unless
experience indicates that re-greasing should occur at more
regular intervals.

9-2 Motor & Belts Servicing
Prior to startup of this machine, it is recommended that the
drive belt tension be checked for proper “RUN IN”
deflection force as listed in column A of the table on page
35.
After the equipment has run between 24 and 48 hours, drive
belt tension must be checked for proper “OPERATIONAL”
deflection as listed in column B of the table on page 35.
A V-belt drive will successfully transmit its rated capacity
if the belts are properly tensioned. The method of
tensioning is explained here in detail for your information.
