3-1 Grease lubrication
3 - 2
The tester mechanism is composed of high quality ball-screws and slide rails, and they are lubricated with
grease that is made from Li-Soap Grease Lubricant and is water-proof and heat resistant at the delivery. It is
unnecessary to lubricate these mechanical parts with grease within one year after delivered. However, after
the tester was used for more than a year, you are recommended to check if grease film still coats them
periodically (even a half year at least). In case of insufficient grease on them, they must be lubricated with
grease additionally in the manner explained below.
WARNING
Make sure that the tester is powered off and unplugged before starting your operation. Otherwise it could
possibly cause bodily injury or mechanical trouble.
CAUTION
Once grease run out, the moving speed may not only go down, but also the probe contact accuracy may
decrease due to the increased friction. As the result, normal testing would not be performed.
If the mechanical part was lubricated too much, the moving speed may not only go down, but also the
probe contact accuracy may decrease due to the increased friction. As the result, normal testing would not
be performed.
In case that you would lubricate grease by hand directly, be sure to wipe out the old grease in advance.
We will give a simple explanation as to how the mechanical parts on the X-axes should be lubricated with
grease.
