8. In sub-zero temperatures, the unit experiences decreased efficiency due to a change in grease viscosity.
Ensure that the drive source can accommodate this change.
9. Keep away from the input shaft and ZIP CHAIN when the ZCA is in operation to avoid injury.
10. The following loads may cause decreased ZCA performance, adversely affect the service life, and damage
the ZIP CHAIN, drive section, end fitting bracket, etc.
１
) Lateral loads: Provide a linear guide in the direction of travel so bending loads are not applied directly
to the ZIP CHAIN
２
) Shock loads
３
) Overloads
5. Maintenance & Inspection
5.1. Inspection
1. Routine inspection (visual checks)
Check the following items every day before operating the ZCA.
・
Check for defects in appearance (loose bolts or nuts, etc.)
・
Check for unusual movement
・ Check for unusual noises
・
Check for unusual smells
・ Check whether the ZIP CHAIN has enough grease
・
Check for wear on the ZIP CHAIN (Fig. 6)
① Check for the oxidized wear dust (rust color) on the following parts
 Between plates
 Front face and end face of the plates
 Outer circumference of the bushings (ZCA45: pins)
 Extended pins
②
Ensure that bushings and extended pins are not cracked or broken
(Note: The bush is curled and therefore has a seam. This is not a crack.)
If there are any defects, stop the ZCA, perform lock-out-tag-out safety measures on equipment, and conduct
the following periodic inspection
2. Periodic inspection
Check the following items.
・
Check for loose bolts and nuts (every 6 months)
Follow the instructions below.
 Remove all loads

Stop the equipment and perform lock-out-tag-out safety measures.
 Shut off the power source and ensure that power cannot be turned on accidentally
 Perform inspections. When bolts are loose, tighten them to the torque specified in JIS and
take measures to prevent them from loosening.
 Turn on the power and return the ZCA to normal operation
・ Check for damage to the ZIP CHAIN (every 6 months)
Follow the instruction below.
 Remove all loads
 Stop the equipment and perform lock-out-tag-out safety measures
 Shut off the power source and ensure that power cannot be turned on accidentally
 Fully extend the ZIP CHAIN from the unit
 Check for wear on the outer diameter of the bushings or pins. Ensure that the diameter is
within the limits shown in the table below.
