ENGLISH
Make sure that dies are exactly positioned on the area to be crimped; otherwise re-open dies following
instructions as per § 2.4 and position the connector again.
2.4) Crimping
Operate the pump to advance the main ram until the die faces touch.
It is recommended to continue pumping until the maximum pressure valve is activated and a
"click" is heard.
2.5) Die opening
Fully discharge the oil pressure from the pump, to retract the ram and release the crimped connector.
3. MAINTENANCE
The head is robust and requires very little daily maintenance.
Compliance with the following points should help to maintain the optimum performance of the tool.
3.1) Accurate cleaning
Dust, sand and dirt are a danger for any hydraulic device.
Avoid putting the head on muddy or dusty ground. Any dirt particles may score the ram and create
oil leaks.
Every day, after use, the head must be cleaned with a clean cloth, taking care to remove any residual
particles, especially around the moving parts.
3.2) Replacement of the automatic coupler
Use a 22 mm spanner to unscrew the old coupler:
– Remove the obsolete coupler.
– Carefully clean the thread to remove the old sealant.
– Apply Teflon tape to the thread.
– Fit the new automatic coupler and tighten to 30 Nm (22 lbf ft).
The oil pressure in the head must always be completely released before disconnecting the head
from the hose.
3.3) Storage
(Ref. to Fig. 2)
When not in use, the head should be stored and transported in the canvas bag, to prevent damage.
Canvas Bag; ref.: 007; Size 350x105 mm (13.8x4.1 in.); weight 0,13 kg (0.29 lbs).
