SET--UP PROCEDURE
1. Position the peck--feed drill in the fixture, being certain the
unit is in the full retract position (control rod (37) all the way
back).
2. Shut off air supply to the drill.
3. Loosen screws (30), releasing cover (33).
4. Determine the total distance the drill bit must travel (distance
‘‘A’’, figure 4). Also determine the distance from the drill point
to the workpiece (distance ‘‘B’’, figure 4). NOTE: This dis-
tance to be a minimum of .100 inches.
5. To set pre--travel (figure 1), set adjustment knob on the hy-
draulic check (129) to its lowest setting. Push plunger of hy-
draulic check forward to achieve desired pre--travel distance
(this distance should be .005 to .015 inches less than dis-
tance ‘‘B’’ to assure the drill point does not strike the work-
piece during rapid advance.
6. To set the stroke adjustment ‘‘A’’ (figure 1), push adjustment
screw (20) forward (lightly) to take the slack out of plunger in
valve assembly (137). Adjust collar (23) to achieve desired
distance ‘‘A’’ and tighten screw (22) to secure collar.
7. Replace cover (33) and secure with screws (30).
8. Attach air supply to tool. NOTE: Air supply at inlet should not
exceed 110 P.S.I.
9. Set hydraulic check adjustment to a medium setting (approx-
imately 20).
10. Remove cap screw (117)(figure 3). Back meter needle (114)
out against retaining ring and depress start button. Tool
should start and peck at a rapid rate. Turn meter needle (114)
in several turns and depress start button. Peck rate will de-
crease as needle is adjusted inward. When desired peck
rate is achieved, replace cap screw (117).
11. Start the drill, check for proper feed rate. If feed rate is cor-
rect,gotostep13.
12. To adjust feed rate, stop the drill. Increase or decrease feed
rate by rotating hydraulic check knob toward lower numbers
or higher numbers respectively. Continue until desired feed
rate is achieved. ‘‘0’’ equals highest feed rate. ‘‘30’’ equals
lowest feed rate.
13. Depressing the stop button at any point in the cycling of the
tool should cause the tool to retract and shut down complete-
ly. When tool stops, the hydraulic check should return to its
original position.
