Adjust only those screws, which bear directly in line with the Tool Holder.
Tighten the Hold down Screws to about 12 to 24 in-lbs. (1.4 to 2.7 N-m). (Finger tight
using a hex key)
Using the Spanner Wrench, run the Tool Holder to the inward most position.
Note any changes in the feed pressure.
Adjust the remaining Adjustment Set Screws so that the Tool Holder has a smooth,
even feel.
Run the Tool Holder the full length of the Slide Rail.
Tightly lock the Adjustable Slide Rail in place with the Hold-down Screws and fully
snug the Adjustment Set Screws.
Check that the Tool Holder runs smoothly and evenly for the full length of travel.
Readjust as necessary.
The Tool Holder should move snugly.
In general, when the Slide Rail is set correctly, the Feed Sprocket cannot be turned
by hand but may be turned easily with the Spanner Wrench.
The torque on the Spanner Wrench should be about 2 to 5 ft-lbs. (2.7 to 6.8 N-m).
AIR MOTOR LUBRICATION
No direct maintenance is normally required on the Air Motors.
However, the air supply must flow through a filter/regulator/lubricator (FRL) unit or
separate units before arriving at the motor.
The FRL unit must be maintained as required (frequency dependent on the basic air
supply) to keep the water trap drained, filter cleaned and the lubrication oil reservoir
filled so that a drop of oil every 2 to 5 seconds is flowing.
If the Clamshell is to be left idle for 24 hours or more after being run on ‘wet’ air, it
is advisable to squirt oil directly into the motor inlet and run the motor for 2 to 3
seconds. This will prevent rusting and ‘freezing’ of the rotor vanes.
