Safety Instructions

  WARNING

Failure to follow Danfoss process and product instructions and limitations 
could lead to premature hose assembly failures, resulting in property 
damage, serious injury or death.

Danfoss fitting tolerances are engineered to match Danfoss hose tolerances. 
The use of Danfoss fittings on hose supplied by other manufacturers and/or 
the use of Danfoss hose fittings supplied by other manufacturers, may result 
in the production of unreliable and unsafe hose assemblies and is neither 
recommended nor authorized by Danfoss.

Safety Instructions

1. 

Prevent Unauthorized operation. Do not permit anyone to operate 
this equipment unless they have read and thoroughly understand this 
manual.

2. 

Wear safety glasses.

3. 

Avoid pinch points. Do not rest your hand on the crimp ring. Keep 
your hands clear of all moving parts. Do not allow anyone, other than 
the operator, close to the equipment while it is in operation.

4. 

Maintain dies with care. Dies used in the ET4020 crimp machine are 
sintered powdered metal, offering the best combination of strength 
and wear resistance for long life. Sintered powdered metal dies are 
generally brittle and care should be taken to avoid any sharp impact. 
Never strike a die with a hardened instrument.

5. 

Use only specified Danfoss products. Make hose assemblies using only 
Danfoss hose and fittings specified for this assembly equipment.

6. 

Verify correct crimp diameters. Check and verify correct crimp 
diameters of all fittings after crimping. Do not put any hose assemblies 
into service if the crimp diameters do not meet Danfoss crimp 
specifications.

!

Read and understand the operator’s manual before attempting to operate 
any equipment.

Danfoss hereby disclaims any obligation or liability (including incidental and 
consequential damages) arising from breach of contract, warranty, or tort 
(under negligence or strict liability theories) should Danfoss hose, fittings or 
assembly equipment be used with the hose, fittings or assembly equipment 
supplied by another manufacturer, or in the event that product instructions 
for each specified hose assembly are not followed.

7. 

Make sure all dies are completely in place and the cage is positioned 
properly on the pressure plate.

8. 

Do not over pressurize. Do not exceed the 10,000 psi hydraulic 
pressure supplied to the machine. This setting is preset at the factory 
and should not require adjustment. 
Note: All components used to connect the pump and crimp cylinder 
must meet the criteria set forth in the Material Handling Institute 
Specification #IJ100 for hydraulic jacking applications.

9. 

Die change. Do not insert/remove dies while the power is on.

10.  Secure the equipment to a stable work surface. Prior to operation, 

secure the crimp machine to a stable work surface to prevent the 
equipment from tipping.

11.  Unplug the power supply when not in use.

12.  Keep work area clean. Cluttered areas and benches invite accidents.
