6. Insert the rear pin of the FlexArm into the upper bearing bore of the angle mount as shown in
Figure 4
.
Use care when inserting the pin into the bearings; the pin may need to be tapped by a rubber mallet
into the bearing as it is a snug fit. If the pin slides through the top
bearing, the washer and flat head screw shown in
Figure 4 can be
used to draw the pin completely through the second bearing.
7. Install the unit’s airline into the press-to-release airline fitting.
8. Install a ¼” NPT fitting into the incoming air port on the unit’s filter /
lubricator (see Figure 5). 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.
9. 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.
10. 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.
11. The filter is equipped with an auto drain and will
automatically remove water from the filter bowl.
