Danfoss T-420 Crimp machine operator´s manual December 2022
Table of contents
1. PREVENT UNAUTHORIZED
OPERATION. Do not permit
anyone to operate this
equipment unless they
have read and thoroughly
understood 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 T-420 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 hardened
instrument.
5. USE ONLY SPECIFIED
DANFOSS PRODUCTS.
Make hose assemblies using
only Danfoss's hose and
Danfoss 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 locator bracket, and the
pusher halves are closed
before crimping.
8. DO NOT OVER PRESSURIZE.
Do not exceed the 5,000 psi
hydraulic pressure supplied
to the machine
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. See pages 4-5 for
mounting instructions.
11. UNPLUG THE POWER
SUPPLY WHEN NOT IN
USE.
12. KEEP WORK AREA CLEAN.
Cluttered areas and
benches invite accidents.
13. DO NOT OPERATE
WITHOUT THE BASE
ADAPTER RING IN PLACE.
Safety instructions
T-420 Crimp machine
WARNING
Danfoss's hose and Danfoss hose fittings should only be assembled using
Danfoss approved assembly equipment. Do not use any combinations
of Danfoss's hose, Danfoss hose fittings, or Danfoss assembly equipment
with hose, hose fittings, or assembly equipment supplied by another
manufacturer.
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,
Danfoss hose fittings, or Danfoss assembly equipment be used with
any hose, hose fittings, or assembly equipment supplied by another
manufacturer, or in the event that product instructions for each specified
hose assembly are not followed. (Reference SAE J1273 – Recommended
practice for hydraulic hose assemblies).
WARNING
Failure to follow Danfoss processes and product instructions and
limitations could lead to premature hose assembly failures, resulting in
property damage, serious injury, or death.
Danfoss fitting tolerances are engineering to match Danfoss's hose
tolerances. The combination or use of Danfoss's hose and hose fittings
supplier by another manufacturer may result in the production of
unreliable and/or unsafe hose assemblies and is neither recommended
nor authorized by Danfoss.
Read and understand the operator’s manual before
attempting to operate any equipment.
