6. Slide the rear pin of the FlexArm into the upper
bore of the angle mount as shown in Figure 4.
Note: Use caution not to damage the two roller
bearings in the upper bore of the angle mount.
7. Install the unit’s airline into the press-to-
release airline fitting (see Figure 4).
8. Cut and remove the shipping zip tie strap (see
Figure 4).
9. Install a ¼” NPT fitting into the incoming air
port on the unit’s filter / lubricator (see Figure
4). The supply airline should have a minimum
½” I.D. The unit must have a proper air supply
(90 – 120 psi and 27-28 cfm) at the motor to
generate the torque required to drive the
maximum tap capacity for this unit.
10. Fill the lubricator bowl approximately ¾ full by removing the black fill plug on the top of the lubricator
and pouring oil into the fill port. Use only a quality ISO Grade 32 hydraulic or spindle oil. Never use
Marvel Mystery Oil, synthetic air tool oil, or
similar products.
11. With the motor running, slowly adjust the
lubricator adjustment knob (see Figure 5) so 1-3
drops of oil are dispensed per minute. The site
glass to see the drops is located in the
adjustment knob. Clockwise decreases the flow,
counter-clockwise increases it. NOTE: It may be necessary
to open the adjustment knob considerably before the oil starts to drip. Once oil starts to drip, slowly
close the adjustment knob to achieve the target drip rate of 1-3 drops per minute.
