1. Manual toggle release
For a product with rubber cover, the toggle link mechanism
can easily be released by hitting the round tab on the cover
with a plastic hammer (made of soft material).
Always confirm safety before operating the manual toggle
release. The clamp arm may suddenly operate during manual
release.
For a product with metal cover, the toggle link mechanism can
easily be released by hitting the tab of the knuckle joint with a
plastic hammer (made of soft material) after opening the
cover.
2. Do not disassemble the power clamp
No special maintenance is necessary because the power
clamp has a fully enclosed design to protect the clamp against
welding spatter, and also the power clamp has a contamination
resistant construction.
Do not disassemble any parts other than replaceable parts,
otherwise it may reduce the performance of the clamp cylinder.
3. Tightening torque of spare parts
Please make sure to tighten spare parts recommended in
accordance with the following torque shown in the table.
