STORAGE
If the Clamshell is to be stored or if it will remain out of service for a significant
period of time (30 days or more), it should be thoroughly cleaned lubricated and
sprayed with a rust preventative prior to storage.
Remove the airline Quick Disconnect and spray it with a lightweight oil.
Squirt oil into the male Quick Disconnect.
Reconnect the airline and turn on the Air Motor for 1 or 2 seconds to disperse oil
throughout the vanes and rotor.
ADJUSTMENT OF THE MAIN BEARING PRE-LOAD
Loosen all Bearing Adjustment Lock Screws about 1/2 turn (1 through 24).
Turn in Bearing Adjustment Screws (1, 5, 9, 13, 17, and 21) so that they are
snugged tightly.
This insures that the Bearings are fully pushed forward. Refer to the Bearing
Adjustment Screw locations.
Lightly turn in the remaining Bearing Adjustment Screws in the order shown until all
of the Bearings make contact with the Headstock.
Relax Bearing Adjustment Screws (1, 5, 9, 13, 17, and 21) and resnug them so that
all of the Bearing Adjustment Screws are evenly loaded against the Bearings.
Connect the air supply and apply power to the Clamshell so that it is running at full
speed.
