9 MAINTENANCE AND SERVICE
The ESM301 should be operated in a dry and clean area. Under these circumstances only a few periodic
maintenance operations are required:
9.1 Acme screw lubrication – twice per year
1. Remove the right column cover by loosening the screws, as shown above.
2. Using a brush, apply a small amount of general purpose lithium grease to the lead screw.
3. Cycle the crosshead up and down several times until the newly applied grease has been spread
evenly over the length of the screw. Re-install the column cover.
9.2 Check for loosened grips and attachments – daily
Check to ensure that the grips attached to the force gauge and base plate are firmly secured. Looseness
could result in a potentially hazardous situation.
9.3 Check for loosened components – once per month
1. Remove the test sample from the test stand.
2. Turn off power to the test stand and disconnect the power cord. Attempt to loosen
subcomponents of the test stand (ex. fasteners, brackets, etc). All components should be firmly
attached. If any looseness is detected, stop using the test stand and contact Mark-10 or a
distributor for instructions.
