2 Safety
The operational safety of the P1Z is only guaranteed if it used for the
intended purpose. It is only assured if the P1Z is used:
• to move loads,
• to exert force.
The P1Z is operated with compressed air (other media on request). The
following must also be taken into consideration:
• all of the conditions specified in the order confirmation, these operating
instructions and the P1Z catalog.
All other uses are deemed to be “Not for the intended purpose”.
Failure to observe this instruction could result in the risk of injury or
property damage. We accept no liability for such damages.
Operating personnel
The operator of the overall system must ensure that only authorized and
qualified professional staff handle the P1Z. Authorized professional staff are
the trained technicians working for the operator, the manufacturer and the
service partner.
Safety-conscious work
The information contained in these operating instructions must be observed.
Not permitted: are unauthorized modifications to the P1Z, and work

4.2 Installation
4.2.1 Mechanical
• Make sure the payload is only fastened to the provided fixing points.
• Position the payload in such a way that the forces and tilting moments on
the piston are below the limits specified in the P1Z catalog.
• Use appropriate coupling and connecting procedures to prevent any
constraining forces from external linear loads.
• Observe the permissible weight and speed as specified in the damping
diagram in the P1Z catalog. Compliance with these specifications is
mandatory.
4.2.2 Pneumatic
Switching examples
• Use two 3/2 or one 5/3 directional control valve to control the cylinder. The
normal setting is open.
• Avoid any uncontrolled movements when commissioning or unintentionally
stopping the machine.
• Use filling units, soft-start valves, etc., from the range offered in our catalog.
• Use the control mechanism to ensure that the piston cannot move against
a completely vented cylinder barrel.
• Use throttle check valves from the range in our catalog to set the speed.
These valves are bolted directly into the cylinder.
• Make sure the compressed air ports are sufficiently large.
• Do not position magnetic switches close to ferritic parts or moving loads.
4.3 Lubrication
The P1Z is suitable for operation with oil-free compressed air.
Once they have been operated with oiled compressed air, the cylinders must
continue to be operated with oiled compressed air.

5 Commissioning
All assembly and commissioning works must be performed by
trained personnel!
Caution! Strong magnetic field!
There can be no guarantee that this field will not influence sensitive
equipment in the vicinity, e.g., measuring equipment.
If the holding force between the two magnet stacks on the piston and
carriage is exceeded, the two may separate. The cylinder will then no longer
function (see Section 9.2 ”Connecting the piston and carriage”).
The magnetic pull-off forces for the individual diameters are as follows:
Diameter [mm] Ø16 Ø20 Ø25 Ø32 Ø40
Magnetic force [N] 157 236 383 703 942
When using the equipment for a specific application, make very sure that
these forces are not exceeded.
Risk of crushing.
Linear actuation can produce rapid and forceful linear movements. This can
injure or crush limbs, or cause damages as a result of collisions with other
parts of the system.
Checks that must be performed prior to commissioning:
• Can covers and/or safety guards effectively prevent anyone from reaching
into the moving parts of the cylinder?
• Can the carriage be manually moved over the entire length of travel?
Identify and eliminate any possible areas of collision and check the
functioning of position detection solenoids.
End cushioning on basic model cylinders
• Move the carriage to the center position and fully tighten both end
cushioning screws. Then loosen by about half a turn.
End cushioning on cylinders with parallel rod guidance
See Section 4.4
Warning, automatic movement!
• Slowly vent both cylinder barrels.
• Bleed at one end; the piston moves to an end position.
• Start the overall test run.
• Use the throttle check valve to set the speed.
• Use the damping screw to set the end cushioning.
The setting of the end cushioning must ensure that the cylinder operates
without jolting or vibrating.
6 Decommissioning
Risks arising after the P1Z and/or the entire system have been shut down
Pressure may still be present in the cylinder, in spite of venting.
This can cause uncontrolled movements of the piston.
Consult the operating instructions for the entire system.

7 Maintenance / Service
Caution
Maintenance and repair works may only be performed by trained or
instructed personnel!
Risk of crushing
Maintenance works may only be performed once the machine has been
switched off and the compressed air system has been vented.
Preparation
• Turn off the main switch and make sure it cannot be unintentionally
switched on again.
• Dismantle the necessary parts to ensure the free movement of the
carriage. If necessary, completely dismantle the cylinder.
7.1 Cleaning and lubrication
Only use gentle agents and non-linting cloths to clean the cylinder.
Do not use high-pressure washers!
Basic model:
• P1Z-S16, 20, 32 cylinder:
Clean and lubricate the entire outside of the cylinder barrel using lithium
paste-based grease.
• P1Z-S25, 40 cylinder
Clean the cylinder barrel and grease the lubricating nipples on the
carriage until you see fresh grease.
Use lithium paste-based grease.
Cylinder with parallel rod guidance:
• Use the same lubrication procedure as for the basic model cylinder.
The guide rods and friction bushes do not need lubricating.
7.2 Maintenance intervals
Recommended lubrication intervals: every 500 km.
Please bear in mind that shorter lubrication intervals are necessary if:
• the temperature loads are higher,
• the cylinder is very soiled,
• the cylinder is positioned close to grease-dissolving liquids or vapors.
Please also consult the operating instructions for the entire system!
8 Disposal
Compliance with the regulations and laws governing the disposal of
environmentally harmful substances is absolutely mandatory.

9 Repairs
Please avail yourself of our repair service if your P1Z requires repairs.
9.1 Troubleshooting
Malfunction Possible cause Help
Uneven movement of
the carriage.
Lack of lubrication. Check lubrication, lubricate.
Incorrect use of the throttle
check valve. Always throttle the outlet air.
Soiled cylinder barrel. Clean, lubricate, use cover.
Damaged cylinder barrel. Contact Parker.
Carriage does not travel
to end position.
End cushioning damping
screw tightened to the full.
Loosen the damping screw
slightly.
Magnetic coupling interrupted.
Press the carriage rmly
against the repulsion force into
the end position until the piston
and carriage re-engage
(see also following section).
9.2 Connecting pistons and carriages
Aligning the piston and carriage if they separate
If the piston and carriage separate, e.g., because of a load blockage, they can
be realigned as follows:
1. Depressurize the cylinder. Lock the entire cylinder.
2. Make sure the cylinder is horizontal, then push the inside piston with the
carriage to the end of the piston. (The carriage pushes the piston ahead of it.)
3. Push the carriage back to the other end of the cylinder.
Caution:
When performing the next steps, keep a safe distance away from
the cylinder: Risk of injury.
Do not push the carriage manually onto the piston. Risk of injury.
Do not stand in the extended direction of travel of the piston.
Do not damage the outer surface of the cylinder barrel!
4. Apply compressed air to the side at which the piston is located. Use the
maximum pressure of 7 bar that is permitted for these cylinders.
The piston is accelerated and pushed into the carriage.
5. Depressurize the cylinder.

P1Z series GB
11
6. Test:
Push the cylinder (and – with it – the piston) first to one end position of the
cylinder and then to the other. In both cases, the distance from the center of
the carriage to the respective end plate must be the same.
If the carriage is asymmetrical on the piston, the carriage must be pushed to
that end of the cylinder where the distance to the end plate is smaller.
7. Then push the carriage back approx. 5 mm and lock it into position.
(Clamp or use a spacer to the end plate.)
8. Still observing the safe distance, apply pressure once more (see point 4) to
the side of the cylinder that is not facing the carriage.
9. Again check for correct alignment, as described in point 6).
If the carriage and piston cannot be aligned using this method, the entire
cylinder must be sent in for repair.
10. If the carriage is centered on the piston, the cylinder can be put back into
service once it has been carefully checked for damages.
9.3 Dismantling from the system
Risk of crushing
Particular care is needed when dismantling the P1Z. Read Section 2, page
4 “Safety”, and observe local safety regulations.
Potential risks:
Residual pressure in the lines and control elements
• Slowly depressurize the cylinder/system to eliminate any residual
pressure in the lines and control elements.
Sharp edges
• Protective gloves must be worn to prevent injuries from sharp edges.
Piston movement
• The cylinder/system must be vented slowly to prevent any uncontrolled
movement of the piston.
When installed vertically or at an angle, the piston must be moved to
the lower end position prior to venting to avert the risk of it falling.
