Drive System _________________________________________________________

• The pump should be mounted on a level, horizontal surface,
secured with grade 5 or better fasteners.
• The drive system should be sized to supply the required horse-
power to the pump plus a reserve to insure long life.
• Make certain that all shafts, pulleys or turning parts are properly
guarded.
• Check the ratio of the drive system prior to installation to verify
that the pump will be turning at the proper speed and direction.
• The pump should be set up to engage slowly to avoid initial
torque damage.
Direction of Rotation
• The direction of rotation and RPM are marked on the front of
the pump.
• The direction of rotation required by your drive system should
be determined prior to ordering the pump.
• If during assembly of your unit you find you need the opposite
rotation, call the factory for instructions.

Factory Settings

• The automatic lubrication pumps are set at the factory during
pump testing and should require no further adjustment during
pump installation. The pump should consume 12 o.z.-15 o.z. of
oil per hour. Please contact us if oil usage is outside of these
parameters.
• It is the responsibility of the installer to ensure proper vacuum
and pressure settings and RPM.
