Operation
WPP 15 E | Version 1.02 11
Step 1: position the support blocks on the press table.
Step 2: press the four pins in the support blocks down
on each side so they are fully inserted in the
press table.
This prevents the support blocks from slipping or tilting
during processing.
10.3 Adjusting the horizontal working position
Step 1: align the workpiece so that it is horizontal to the
hydraulic cylinder.
As a result, it cannot tilt during hydraulic cylinder pro-
cessing.
10.4 Aligning hydraulic cylinders
The hydraulic cylinder can be manually moved to the
desired position over the workpiece. For this purpose, it
can be moved towards the left or right.
10.5 Building up pump pressure
Step 1: move the switching valve to the right-hand posi-
tion to access the hydraulic cylinder for filling.
Step 2: move the pump lever and the pedal up and
down until the stamp comes into contact with the
workpiece. Fill the hydraulic cylinder with oil.
Step 3: continue to pump until the required pump pres-
sure has built up. For this purpose, monitor the
pressure gauge.
The pump pressure can also be built up using the pneumatic
foot-operated pump.
For this purpose, operate the pneumatic foot-operated
pump and proceed as described for the pump lever un-
til the required pressure has been built up.
10.6 Marking the cylinder limit position
Fig. 9: Cylinder limit position mark on the piston rod
1 - Cylinder
2 - Limit position mark on the piston rod
3 - Piston rod
If the marking on the piston rod [2] becomes visible dur-
ing the pressing process, the pressing process must be
terminated to prevent potential damage to the cylinder.
In the event of non-observance and continued pumping
the cylinder will be damaged with the result that the cyl-
inder may no longer retract correctly.
Retract the cylinder if the pressing process was insuffi-
cient up to the mark (see section 10.7). In this case, ele-
vate the press table and repeat the pressing process
(from section 10.2).
10.7 Retracting hydraulic cylinders
IMPORTANT!
Make sure the workpiece has been centred under
the piston!
NOTE!
Monitor both the working area and the pressure
gauge during pressing to exclude potential damage
to the press or workpiece caused by overloads.
IMPORTANT!
- Do not exceed the press capacity!
- Do not use extensions for the pressure lever
NOTE!
Monitor both the work area and the piston rod during
the pressing process for the purpose of marking the
limit position to prevent potential damage to the cyl-
inders caused by overloads.
Tips and recommendations
The manufacturer has already configured the
retracting speed of the hydraulic cylinder. Modifica-
tions are required or permitted following mainte-
nance work or repairs only. For this reason, the
adjusting screw has been covered.

Disposal, reusing used machines
11.2.5 Oil changes
Draining oil:
Step 1: open the screw connection on the retracted hy-
draulic cylinder.
Step 2: pump out the hydraulic oil and collect it in a suit-
able container using a hose.
Topping up oil:
Step 1: retract the piston so that it is in the base position.
Step 2: top up new oil via the filler neck.
Step 3: vent the hydraulic system. For this purpose, turn
the switching valve in anti-clockwise direction.
Operate the pump lever several times to remove
the air from the hydraulic system. Then once
again close the switching valve.
12 Disposal, reusing used machines
In your own interest and to protect the environment
make sure that all machine components are exclusively
disposed of in as intended and permitted.
12.1 Decommissioning
Disused machines must be decommissioned immedi-
ately to prevent misuse at a later point and putting the
environment or persons at risk.
Step 1: remove all environmentally hazardous process-
ing materials from the used machine.
Step 2: if necessary, disassemble the machine into as-
semblies and components that are easy to han-
dle and suitable for recycling.
Step 3: the machine components and processing mate-
rials must be disposed of using the intended dis-
posal methods.
12.2 Disposing of lubricants
Remove escaping, used or excess grease from the lu-
brication points featuring lubricant.
Lubricant manufacturers provide disposal information
for the lubricants used. If necessary, request product-
specific data sheets.
13 Liability for defects (warranty)
Our customers also represent consumers and they are subject
to statutory regulations. Customers must give us the opportu-
nity to audit the defect and transport the goods to our work-
shops for auditing upon our request and at our expense. The
following applies to our commercial customers:
(1) Customers shall check delivered goods for defects immedi-
ately on delivery. In this process, any identified, obvious dam-
age must be immediately indicated in writing. Transport
damage and missing packaging items shall also be reported
to the haulage company immediately. Any defects that were
not identified despite thorough inspections shall be reported in
writing immediately after having been identified. In this case,
our customer must immediately stop processing and using the
ordered goods. Customers must give us the opportunity to
audit the defect and transport the goods to our workshops for
auditing upon our request and at our expense. After having
carried out a mutually agreed approval, any indication of
defects that were identified upon approval shall be excluded.
The statutory period of liability for defects of two years shall not
apply to commercial customers.
(2) The period of liability for defects shall be one year from the
transfer of risk, providing no other periods have been specified
in agreements or statutory regulations. If the manufacturer of
the item subject to delivery grants a longer period of liability for
defects or a warranty, we shall transfer our resulting rights to
the ordering party/purchaser upon making the purchase. We
can provide an up-to-date list of individual periods of liability
for defects and their terms and conditions as well as warranty
periods and their terms and conditions as specified by the
manufacturer.
(3) In the event of a warranty case we shall carry out improve-
ments or provide replacement deliveries following coordination
with the manufacturer. We shall not be obliged to reimburse
any incurred costs, in particular for transport, travelling, labour
and material caused by transporting the item subject to the
purchase to a different location than the place of fulfilment,
unless specified in the statutory regulations. If any improve-
ments or replacement deliveries as a result of defects fail twice
(provide verification) or if the elimination of the defect would
incur unfeasibly high costs, causing improvements to be
denied, customers shall be permitted to demand either a
reduction of the price or annulment of the contract. We hereby
notify customers that there shall be no liability for defects in
particular for damage caused at customer premises as a result
of misuse or unintended use as well as for damage caused by
subjecting products to damaging, external influences at cus-
tomer premises (in particular extreme temperatures, humidity,
extraordinary physical or electrical loads, voltage fluctuations,
lighting strikes, static electricity, fire).
(4) If audits as part of claims for liability for defects result in that
the claim has been unjustified, we shall be authorised to
charge a conventionally applicable remuneration for the audit
of the goods as well as shipping costs.
(5) Our warranty shall not apply to natural wear, incorrect use
and storage, incorrect installation or damage caused after the
transfer of risk as a result of incorrect or irresponsible handling,
excessive use, unsuitable processing materials or as a result
of other influences that have not been specified in the contract.
(6) Any repairs carried out by ordering parties/purchasers or
third parties without our consent or incorrect repairs by a ser-
vice partner that has not been authorised by the manufacturer
shall render any claims for liability for defects void.
NOTE!
Dispose of the removed oil separately.
Consult the lubricant manufacturer for appropriate
information.

(7) In the event of active, contractual infringements, delays,
non-performance, unauthorised actions or any other legal rea-
son (except infringements occurring prior to conclusion of the
contract) we shall be liable in case of intent or gross negli-
gence only. In the event of culpable damage to life, health or
injuries, in case of culpable infringements of major, contractual
obligations (main contractual obligations) or in the event of
malicious actions and claims for replacement as per Article
437, Section 2 of the German Civil Code (BGB), we shall be lia-
ble as per the statutory regulations, whereby our liability in the
event of an infringement of major, contractual obligations shall
be restricted to the typical, foreseeable damage. The term
"major, contractual obligations" shall either be used to specify
a specifically described, paramount infringement of obliga-
tions that put the objective of the contract at risk or, in abstract
terms, it shall be defined as an obligation as part of which its
compliance guarantees the correct implementation of the con-
tract on which customers can rely on a regular basis. In the
event of delays, customers shall be permitted to demand com-
pensation or alternatively withdraw from the contract.
(8) In the event of a loss of data we shall exclusively be liable if
our customers can verify that they have backed up the data
once a day (at minimum). The liability for data loss shall be
restricted to the recovery costs if there are backups, unless we
caused the data loss intentionally or as a result of gross negli-
gence. In any other case, except in the event of intent or gross
negligence, liability shall be excluded.
(9) The scope of our liability as per product liability legislation
shall remain unaffected.
