6.10 Lubricating the Cables and Linear Guides
The XYZ-axes support the dispensing head and allow it to travel within the dispensing area. To ensure
smooth dispensing head movement, the cables and linear guides must be lubricated approximately every
three months.
NOTE To perform the following procedures, you will need Asymtek Grease Kit (Item 58). The
kit contains a grease pump, two cartridges of grease, and a lint-free cloth.
Tools and Materials Needed
• Safety Glasses
• Rubber Gloves
WARNING! Refer to the applicable Safety Data Sheet for materials used in this procedure for
important safety information.
6.10.1 Loading the Grease Gun
To load the grease gun:
1. Unscrew and remove the grease pump from the grease gun canister.
2. Remove the cap from the grease cartridge.
3. Remove the seal and screw the grease cartridge into the grease pump.
4. Fit the canister of the grease gun over the grease cartridge and screw into the grease pump.
5. Screw the nozzle into the grease pump.
6. Screw the grease fitting adapte
r into the nozzle.
7. Purge the air from the grease gun cartridge by dispensing grease into a waste receptacle
until a solid stream flows from the grease gun.
6.10.1 Lubricating the Cables
NOTE Use Moly-Graph grease included in the Grease Kit (Item 58). DO NOT USE FOR
CLEANROOM SYSTEMS! See warning below.
WARNING! For S2-9X0 Series Cleanroom Systems, use only NSK Clean Grease LG2
(Item 58) included in your grease kit.
To lubricate the cables:
1. Perform a service shutdown, see 2.14 Service Shutdown.
2. Open the dispensing area door.
3. Remove the axis and cable covers, see 6.9 Removing and Installing the Axis Covers.

4. Manual move the dispensing head to the front middle of the dispensing area.
5. Wearing gloves, clean all accessible cables using a soft lint-free cloth (Item 58).
DO NOT clean the cables with isopropyl alcohol. Doing so will damage the nylon
jacket.
WARNING! Use Personal Protective Equipment (PPE) when working with cleaning and
lubrication materials. Refer to the applicable Safety Data Sheet (SDS). Remove
all spills and properly dispose of contaminated materials.
6. Visually inspect the cleaned cables for uneven and excessive wear.
NOTE 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.
7. Wearing rubber gloves, manually apply 2.8-3.0 grams of Moly-Graph grease to the exposed
portion of all mechanical cables.
2.8-3.0 grams is the amount Asymtek has determined to be optimal for performance
without spattering the grease from cables to parts. If you are experiencing this issue,
reduce the amount of grease on the cables.
8. Move the X-beam to the rear of the machine and apply grease to all exposed cables on the
left and right sides of the machine.
WARNING! Fingers may be pinched if the dispensing head is moved while cleaning and
lubricating the cables.
9. Move the X-beam to the front of the machine and apply grease to all exposed cables on the
left and right sides of the machine.
10. Move the Z-head to the left side of the X-beam and apply grease to all exposed cables on
the X-beam.
11. Move the Z-head to the right side of the X-beam and apply grease to all exposed cables on
the X-beam.
12. While an assistant is moving the X-beam SLOWLY in the Y-direction from bump stop to
bump stop, apply grease to the exposed cables near the Y-motor drive pulley.
13. While an assistant is moving the X-beam SLOWLY in the X-direction from bump stop to
bump stop, apply grease to the exposed cables near the X-motor drive pulley.
NOTE Do not apply grease directly to the drive pulleys or cable pulleys as this will
over grease the mechanics.
14. Manually exercise the X/Y mechanics fully in all directions.
15. Wipe excess grease off drive pulleys, motor pulleys, cables, and frame.
16. Install the X- and Y-axis covers, see 6.9 Removing and Installing the Axis Covers.
