Lubrication

z Thoroughly remove anti-rust oil and feed lubricant before using the product.
z Do not mix different lubricants. Even grease containing the same type of thickening agent
may, if mixed, interact in an adverse manner due to disparate additives or other ingredients.
Check lubricant
z When using the product in locations subject to constant vibrations or in special environments
such as in clean rooms, vacuums, and under low or high temperatures, be sure to use a
lubricant suitable for the specifications and environment.
z When lubricating products that do not feature a grease nipple or oil hole, directly coat the
raceway surfaces with lubricant and perform several warm-up strokes to ensure that the
grease permeates the interior.
Grease consistency can vary depending on the temperature. Keep in mind that the LM Guide
sliding resistance will be affected by changes in consistency.
z Following greasing, the stirring resistance of the grease can cause the LM Guide to exhibit
increased rolling resistance. Before commencing operations, make sure to run the unit
through several warm-up cycles to ensure that the grease is adequately integrated and
dispersed.
z Excess grease may spatter immediately after lubrication. Wipe off spattered grease as
necessary.
z The properties of the grease deteriorate over time, thereby degrading the lubricity. It is
necessary to inspect and apply the grease in accordance with the usage frequency.
z How often grease should be replenished varies depending on the usage conditions and
environment. We recommend greasing the system approximately every 100 km traveled (three
to six months). Final greasing interval/amount should be set at an actual machine.
z If the installation direction is other than horizontal use, the lubricant may not reach the
raceway completely. See the general catalog for information regarding installation direction
and lubrication.
z When using oil lubrication, the lubricant may not be distributed throughout the LM Guide
depending on the installation direction of the LM block. Contact THK for details.

Storage

Store the LM Guide horizontally in its original packaging in an indoor location where it is not ex-
posed to high or low temperatures or high humidity.
Please note that if the product has been kept in storage for an extended period of time, the lubri-
cant inside may have deteriorated. Please therefore ensure that you replenish the lubricant be-
fore re-use.

Disposal

The product should be disposed of appropriately as industrial waste.
