Read and understand the operator’s manual 
before attempting to operate any equipment. 
!WARNING
Aeroquip hose, hose fittings and assembly 
equipment should be used only with other 
Aeroquip hose, hose fittings and assembly 
equipment and Weather-head hose, hose 
fittings and assembly equipment should 
be used only with Weatherhead hose, hose 
fittings and assembly equipment. Do not 
combine or use Aeroquip or Weatherhead 
hose, hose fittings and assembly equipment 
with each other, i.e. Aeroquip hose with 
Weatherhead fittings, or with hose, hose 
fittings or assembly equipment supplied by 
an-other manufacturer. 
Danfoss hereby disclaims any obligation or 
liability (including incidental and consequen-
tial damages) arising from breach of contract, 
warranty, or tort (under negligence or strict 
liability theories) should Aeroquip or Weath-
erhead hose fittings or assembly equipment 
be used interchangeably or with any hose, 
fittings or assembly equipment supplied by 
another manufacturer, or in the event that 
product instructions for each specified hose 
assembly are not followed.
!WARNING
 Failure to follow process and product instruc-
tions and limitations could lead to premature 
hose assembly failures, resulting in property 
damage, serious injury or death. Aeroquip and 
Weatherhead fitting tolerances are engineered 
to match Aeroquip and Weatherhead hose tol-
erances. The combination or use of Aeroquip 
or Weatherhead hose and hose fittings with 
each other, i.e. Aeroquip hose with Weather-
head fittings, or with hose or fittings supplied 
by another manufacturer may result in the 
production of unreliable and/or unsafe hose 
assemblies and is neither recommended or 
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 any-
one, other than the operator, close to the 
equipment while it is in operation.
4. MAINTAIN DIES WITH CARE. Dies used in 
the ET1187 crimp machine are hardened 
steel, offering the best combination of 
strength and wear resistance for long life. 
Hardened dies are generally brittle and 
care should be taken to avoid any sharp 
impact. Never strike a die with a hard-
ened instrument.
5. USE ONLY SPECIFIED AEROQUIP/ 
WEATHERHEAD PRODUCTS. Make hose 
assemblies using only Aeroquip and 
Weatherhead 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.
7. Make sure all dies are completely in 
place, the spacer ring rests against the 
placement pins, and the pusher is pulled 
forward into the detent position before 
crimping.
8. DO NOT OVER PRESSURIZE. Do not exceed 
the 10,000 psi hydraulic pressure supplied 
to the machine. 
 NOTE: All components used to connect 
the pump and crimp cylinder must meet 
the criteria set forth in the Material Han-
dling Institute Specification #IJ100 for 
hydraulic jacking applications.
9. DIE CHANGE. DO NOT INSERT/REMOVE 
DIES WHILE THE POWER IS ON OR 
MACHINE IS IN OPERATION.
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 AREACLEAN. Cluttered areas 
and benches invite accidents.
