Cleaning
Do not clean with solvents or abrasive cleaners. Some household or commercial
cleaners can react with painted surfaces or panel markings.
Do not apply excessive amounts of detergent cleaner. It may seep into electrical circuits
within the base and cause equipment failure.
Do not use too much oil. It attracts abrasive particles that may accelerate wear.
Use low pressure air to blow dust. Do not direct the air stream directly at sensitive
components.
It is recommended that the machine be cleaned weekly, or more often if it is operating
in a dusty or dirty environment.
To clean the load frame, wipe exterior surfaces of the load frame with a moist cloth.
Lubrication
The following areas of the machine will require periodic lubrication:
• Ballscrews - The ballscrews are lubricated via a ballnut that is located on the
crosshead where the ballscrew intersects the crosshead. As the crosshead moves
up and down, the ballnut disperses a thin layer of lubricant over each ballscrew as
the ballscrew passes through the ballnut. Periodically, the ballnut must be filled with
lubricant to ensure that the ballscrews remain well lubricated. The ballnut must be
maintained and filled in accordance with Table 10 on page 114.
Inspect the ballscrew and lubricate more frequently if any of the following conditions
exist:
• There is high-load or high-speed testing.
• There is long-term, continuous movement of the crosshead.
• The system operates in a dirty environment.
• There are high-load cycling tests.
• Linear Guide Carriages - These should be lubricated at the same time as the
ballnuts.
• Guide columns - The guide columns require only a thin film of lubrication. It is
recommended that the machine be re-lubricated every two years.
The guide column is located behind the ballscrew. If you suspect that the guide
column needs lubrication, contact Instron
