3. Assembly, installation and commissioning
3.1 Unpacking and fitting
• Remove packaging materials. Check all parts for transport damage. If any damage is
apparent, inform carrier immediately.
3�2 Trial run
• We recommend pumping the cylinder a number of times through a complete stroke
before use (also after extended periods without use). See chapter 4.
3�3 Aids to be supplied by the user
• Personal protective equipment. See paragraph 1.6.
• Safety blankets if not included.
4. Operation
4�1 General operation
WARNING!
• Never heat a job that is connected to the BETEX Hydraulic Puller as the heat
can damage parts of the BETEX Hydraulic Puller.
Remove the pulley remover from its case. Keep your place of work tidy. Remove excess
grease from the workpiece to be removed or mounted.
4�2 Removing jobs using an HXP puller
The HXP pullers can be used with 2 or 3
puller arms. It is recommended that the
3-arm configuration is used whenever
possible, as this distributes the puller
force better.
The puller must be inspected for damage
before every use. Any loose bolts must
also be re-tightened!
1. Select the right puller for the removal.
See the figure in section 7.1.
2. Connect the external pump. The
connector can be rotated 360°.
3. Loosen the ring of the cylinder to open the arms. Place the puller and the arms around
the workpiece to be removed. Tighten the ring so that the arms grip firmly around the
workpiece. Back off the press cylinder further so that the arms grip firmly behind the
workpiece. If necessary, adapters can be placed between the plunger and the shaft. Start to
pump. Stop when the plunger contacts the shaft and check whether the puller is clamped
correctly at all 2 or 3 points. The puller must be in line with the workpiece to be removed.
4. Place the safety blanket around the puller and the workpiece to be removed.
5. Start to pump. The plunger presses against the shaft and the workpiece comes loose.
If the workpiece does not come loose, the capacity of the puller is not sufficient for this
application.
6. Allow the plunger to retract fully. Loosen the ring of the cylinder to open the arms.
7. Check that the system is completely free of pressure. Then disconnect the external pump.
8. Clean the puller and store it after use in the carrying case supplied.
