6. CAUTION
1) Basically, regular maintenance work is not necessary for this unit.
In case of using the unit at the dusty environment, clean the inside of the housing regularly.
Wipe dust and oil off especially the slide part of the unit with an alcohol-moistened cloth.
2) Use the designated springs.
3) Set the moving speed of the weld head with the P-unit loaded at the followings:
20N:
slower than 50mm/s
50N:
slower than 80mm/s
200N: slower than 200mm/s
500N: slower than 200mm/s
The impact that occurs when the application comes back to the starting point is stronger than the
one that occurs when pressuring is stopped.
Consult us if you would like to use it at faster speed than the recommended speed.
4) The load cell of 50N or less may be damaged if transported by being attached to the P-unit.
When transporting the load cell, be sure to remove it from the P-unit and pack it separately.
NOTE: To the customers who have replaced an old version of P-unit with a new version:

provides lower friction of the inside parts. Please make sure of following the instructions below.
a. The moving speed of the weld head must be set as mentioned above.
b. Set the squeeze time long. The squeeze time depends on each pressure set value,
pressure spring, loaded head speed, and application. Examine proper squeeze time while
actually operating. Unless the squeeze time is set long enough, the measuring value
won’t be stable.
