4. Operation
Caution
(1) For cylinders with locking mechanism, do not apply external force from the opposite side
when the lever is locked.
Lower the cylinder before adjusting the conveyor or moving the pallet.
(2) For cylinders with locking mechanism, do not allow the pallet and roller to collide when the
lever is locked.
If the pallet collides with the roller in the locked state, it may cause lever malfunction. (The lever is
released when the cylinder is fully retracted.)
(3) For cylinders with locking mechanism, do not remove the grease applied to the lock pin.
If the cylinders are operated without grease, the lock / unlock may malfunction due to excessive wear
of the lock pin. Periodically check the lock pin is adequately greased, apply grease as necessary.
Grease No
：
GR-S-010 (10g)
Do not remove the grease applied to the piston rod end of the built-in shock absorber. Periodically check
the condition of this and apply grease as necessary.
(4) Do not let your hand become caught when operating the cylinder.
The lever holder goes up and down while the cylinder is in operation. Take care not to get your
hand or fingers caught between the rod cover and lever holder.
(5) Do not let water, cutting oil or dust splash on the equipment.
This can cause oil leakage and malfunction of the shock absorber.
(6) The stopping condition of the transferred object may vary due to changes in ambient
temperature or changes in the shock absorber resistance over time.
Check the stopping condition periodically and adjust the shock absorber resistance as necessary.
