General Hints to Danger
STOP D A N G E R !
With assembly and disassembly of the PIK’s it has to be made sure that the entire
drive train is protected against unintentional engagement. You can be seriously
hurt by rotating parts. Please make absolutely sure to read through and observe
the following safety instructions.
• All operations on and with the PIK have to be performed taking into account "safety first".
• Please make sure to disengage the power pack before you perform your work at the PIK.
• Protect the power pack against unintentional engagement, e. g. by providing hints at the place of
engagement or removing the fuse for current supply.
• Do not touch the operation area of the machine as long as it is in operation.
• Please protect the rotating drive parts against unintentional touch. Please provide for the necessary
protection devices and caps.
Proper Use
You may only assemble and disassemble the PIK if you
• have carefully read through the mounting instructions and understood them
• and if you are authorized and have proper skills
The PIK ring may only be used in accordance with the technical data (see hydraulic components
catalogue). Unauthorized modifications on the PIK design are not admissible. We do not take any
warranty for resulting damages. To further develop the product we reserve the right for technical
modifications.
The PIK described in here corresponds to the technical status at the time of printing of these mounting
instructions.

Hints concerning the PIK
• The max. permissible operating pressure for the installed heat exchanger is 15 bar.
! C A U T I O N !
Peak pressures must be avoided.
The permanent operating pressure should not exceed 10 bar during static
operation and be max. 6 bar in case of pulsating dynamical load. In case of
dynamical load peak pressures of more than 10 bar must be avoided.
A T T E N T I O N !
The sense of rotation of the engine is right - from the pump shaft!
• Please see diagrams 1 to 8 regarding the permissible oil quantity flowing through and the pressure
difference. If the max. permissible quantities flow through, please make sure that there is a free
flowing-through of the cooler output line in order to avoid peak pressures.
A T T E N T I O N !
Please consult with our Engineering Department in case of quantities flowing
through which are higher than indicated in these diagrams.
• The position to assemble the PIK oil cooler is optional.
! C A U T I O N !
Please make sure that there is free space approx. 10 cm in front of and behind
of the air input and air output. The performance of the PIK is increased by the
natural flow direction of warm air if the air output is on the top.
The fixing threads of the PIK feet are respectively arranged.

Assembly / Starting the PIK
Continuation:
• You generally need fixing threads to fix the PIK feet.
The nylon stoppers in the threads must be removed before the assembly.
Hexagon socket screws acc. to DIN EN ISO 4762 must be used.
The tightening torque T A of the screws to the PIK is indicated in table 1.
• Fixing threads are generally planned to fix the tank (type V1).
The nylon stoppers in the threads must be removed before the assembly.
The screw tightening torques of the screws from the tank cover to the PIK are indicated in table 1.
! C A U T I O N !
The oil connection pieces must show to the direction of the engine (The heat
exchanger can be turned if V1 is used)!
• The fan wheel must be pushed onto the engine shaft until the stop and secured against axial
displacement.
Safety device against axial displacement:
Fan wheel with radial safety device: The screw tightening torques for the assembly of the fan
wheel are shown in table 2 (see picture 3).

• The mounting instructions for the respective coupling type are generally valid for the assembly of
the coupling. The dimensions for the assembly of the coupling hubs are shown on the drawing of
the respective engine-pump combination.
• The DT damping ring can only be used in the variation DT.../2.
Before the assembly the nylon caps in the threads must be removed.
Hexagon socket screws acc. to DIN EN ISO 4762 must be used.
The DT damping ring must be screwed with the PIK. Please make sure that the hexagon socket
screws are plugged into the DT damping ring through the cylinder bores and screwed into the PIK
housing.
The tightening torques of the screws from the DT damping ring to the PIK housing are mentioned

Frequently Answers and Questions
How often does the PIK - Oil cooler need to be maintained?
The PIK oil coolers are maintenance-free. Due to the vacuum principle and airflow, dirt can be cleaned from the outside without disassembling the heat exchanger.
What is the max. oil temperature I can use with the PIK - Oil cooler?
Before initial operation, ensure the max. oil temperature does not exceed +80 °C.
Where should I position the PIK - Oil cooler in the hydraulics circle?
The PIK oil cooler should be the last element in the oil circulation to avoid pressure buildup. Filter units should be positioned in front of the PIK.
What is the maximum tightening torque for the PIK oil cooler?
The maximum tightening torque for the PIK oil cooler is 40 Nm.
Which type of screws should I use for assembling the PIK - Oil cooler?
Use hexagon socket screws according to DIN EN ISO 4762. The tightening torques are specified in the manual.
