Level 2 Maintenance, X-1000 Series Dispensing Systems 3-28 P/N 196515 (Revision A)
Exercise Sheet 3-6-1
Lubricating the Positioner Cables
Verify that the Main Power Circuit Breaker is locked out and the facility
air supply is disconnected from the Main Air Inlet before attempting this
procedure or serious injury may occur.
Use Personal Protective Equipment when working with cleaning and
lubrication materials. Refer to the applicable MSDS. Remove all spills
and properly dispose of contaminated materials.
This procedure assumes that there is access to the sides and back of the
dispensing system. This procedure is performed more efficiently if the service
technician has an assistant.
Tools and Materials Needed:
• Safety Glasses • Grease, Lithium (Moly-Graph Grey)
• 4-mm Hex Key • Isopropyl Alcohol
• Rubber Gloves • Soft, Lint-free Cloth
1. Perform a Service Shutdown as specified in Information Sheet 1-3-2 on page 1-11.
2. Remove the 4-mm screws attaching the Motor Cover, Motor Access Panel, and two Rear
Safety Covers on the back of the dispensing system (See Diagram Sheet 3-6-1 on page
3-29).
3. Disconnect the electrical cables from the rear of the X and Y Servo Motors.
CAUTION! If the motor cables are not disconnected, rapid movement of the
Positioner during this procedure will generate electrical current that may damage the
X and Y Servo Motor drive circuitry.
4. Remove dispensing system side panels as shown in Diagram Sheet 3-6-1 on page 3-29.
5. Open the dispensing system Hatch and move the Dispensing Head to the front middle of
the dispensing area.
6. Wearing gloves, clean all accessible cables using a soft lint-free cloth and isopropyl
alcohol.
Fingers may be pinched if the Dispensing Head is moved while cleaning and
lubricating the cables
7. Visually inspect the cleaned cables for uneven and excessive wear. Run a lint-free cloth
over cables while feeling for breaks in sheathing or swollen spots.
If the cables show signs of wear, skip this procedure and contact Asymtek. If the
cables show no signs of wear, proceed with the next step.
8. Move the Dispensing Head to the rear middle of the dispensing area and repeat Steps 5
and 6.
9. Wearing rubber gloves, apply an adequate but not excessive amount of grease with
your gloved fingertips to the exposed portion of all mechanical cables.
Moving the Dispensing Head in the X and Y direction while applying the grease to the
motor pulley simplifies this step.
10. Manually move the carriage to the front middle of the system and repeat Step 8.
11. From the rear of the system, repeat Step 8 for the X and Y cables on the Motor Pulleys.
