A-4SC/A-5SC Set-Up Procedure
1. CAUTION Before connecting the air compressor:
a. Make sure that all lock pins are in their locked position.
b. Make sure all controls are in the “off” position and the lift lever (if so equipped) is in the “up” position.
c. Make sure the lubricator is filled with proper lubricant. See recommended lubricants below.
d. Make sure air line is cleaned out and is of the proper size and pressure rating for the drill unit.
e. Make sure that the air compressor is set at an operating pressure of not more than 120 PSIG (8 Bar).
f. Install the drill steel and bits into the drill motors and close the latch retainers and rod guides.
2. Connect the air line to the drill in accordance with hose connection instructions.
3. Start the compressor in accordance with manufacturer’s instructions.
4. Position the drill unit where the first set of holes is to be drilled, keeping the drill unit back from the edge of the slab
slightly. Set the brake if so equipped.
5. With the lift lock still engaged, charge the lift cylinder by toggling the lift lever up and down.
6. With the lift valve in the up position and after making sure that there are no obstructions in the path of the drill bed,
remove the lift lock pin.
7. Using the lift lever, lower the drill bed into the drilling position.
8. Measure the drilling position from the top of the slab to the center of the drill steel. If necessary loosen the locknuts
and, using the adjusting screws to raise or lower the drill bed to the proper drilling position. Tighten the locknuts.
9. Check to make sure the drill bed is parallel with the slab that is to be drilled into. If necessary, loosen the locknut on
the lift cylinder and turn the adjusting screw in or out to align the drill bed with the slab to be drilled.
10. To set the drill depth, remove all the rail locking pins and feed the drill bit into the face of the slab without turning on
the drills.
a. On Standard Machines: Measure the distance between the drill stop rod and the drill stop pad. Adjust the
stop bolt so that the distance between the stop pad and the stop bolt equals the drill depth.
b. On Wireless Machines: Measure the distance that the feed cylinder rod extended. Add this distance to the
required drill depth. Measure along the feed cylinder tube from the trunnion end to the position sensor;
adjust the sensor so that it is set at the distance determined above. Note: After drilling the first hole with
each drill, it is recommended to measure the actual drill depth and then readjust the position sensor
accordingly.
11. Set the feed regulator to 20-24 PSIG (1.4-1.7 Bar).
12. See operating instructions to drill the first set of holes.
