In order to assure many years of trouble-free service from any ADC system, thefollowing guidelines should be followed. Each of the suggestions below has beenclassified as to its recommended frequency. If any damage is discovered, or if anyquestions should arise, contact ADC or the representative for additional information.

A. Daily Inspection

1. Inspect the test chamber. Remove any debris or broken balls from thesystem.

2. Inspect the ball rails inside and outside of the chamber. Remove any debris,dirt or dust from the rails.

3. Check for any loosened bolts and screws, especially in the area of movingparts.

4. Inspect all airlines and wires to detect any pinching or chafing. Repair orrelocate as necessary.

5. Add air power to the system and inspect all airlines and fitting for leaks. If anyare detected, remove the air power from the system and make the necessaryrepair.

B. Weekly Inspection

1. Inspect and clean all sensors, especially any photo-eyes and particularly theADC iBeam sensors. Any dust or dirt on the sensing surfaces could affectthe operation and sensing capability of the visual sensors.

2. Refer to Figure 1. Check the water level in the moisture-collection filter andempty it if the level is above the safe operating point.

3. Again, refer to Figure 1. Inspect the dust-collection filter to assure that thefilter is clean and not clogged with debris.

BEFORE ATTEMPTING MAINTENANCE ONANY ADC SYSTEM, REMOVE ALL

ELECTRICAL POWER AND COMPRESSEDAIR FROM THE SYSTEM.

C. Monthly Inspection

1. ADC Ball Cannon, Style II(Available on all ADC Systems) Refer to Figure 2

Carefully inspect the cannon, outer & inner surfaces.

Remove any debris and dirt from all cannon surfaces.

Verify that all screws and bolts are tight.

Verify that the Cannon Ball Retaining Rod is tight and in the properposition.

Using a rag and a suitable rod, clean the firing tube inner surface. Apply alight oil lubricant to the tube inner surface.

Apply a white silicon grease lubricant to the cannon breech slide.

2. Club Clamping Mechanism(ADC ClubTesters ONLY) Refer to Figure 3 &4.

Inspect the Club Clamping for any wear or misalignment of the clampingblocks.

Clean the surfaces of the slide shafts of both the horizontal and verticalslides. Apply a white silicon lubricant and remove any excess lubricantfrom the mechanism.

3. Ball Accumulation-Style Elevator(ADC ClubTesters ONLY) Refer to Figure5

Carefully inspect the elevator assembly.

Remove any debris or dirt from the assembly.

Verify that all screws, bolts are tight. Check all air lines.

Verify that the photo-eye is clean and tight.

Apply white silicon lubricant to the air cylinder rods as shown below.

5. Inspect theBall Size-Checker(Available on ALL ADC Systems).

Clean all surfaces and remove any debris that may affect function.

Carefully remove the yellow guard and apply white silicon lubrication to

the bronze slides and the cylinder rod. Verify that the photo-eye is clean and unobstructed.

D. Semi-Annual Inspection

1. (ADC ClubTesters ONLY) Refer to Figure 6. Inspect the club Stabilizermechanism for wear. Assure that the device is properly adjusted for the bestperformance.

2. (Available on ALL ADC Systems) Inspect the Ball Catch Tarp and theCannon Ball seal for wear. If these items are worn, contact ADC or theirauthorized representative for replacement parts.
