When both hoses and control cord are connected to the HydraPac, the pull and return cycles of the tool are controlled by depressing
and releasing the trigger switch located in the handle respectively.
When the switch is depressed the solenoid valve located in the HydraPac is energised and directs the pressurised oil flow to the pull
side of the piston in the tool. This also allows the oil in the return side of the tool to return to the tank. The piston/collet assembly
now moves towards the rear of the tool allowing the cushion to push the follower and jaws forward. If a Avdelok
inserted in the nose for assembly, the jaw set will clamp onto the pintail and assembly will commence.
The cycle of installation will first clamp the joint to be fastened and then as the anvil continues to move forward the collar will be
swaged into the locking grooves of the pin. At the end of the swaging cycle the anvil will come hard up against the joint and as
movement continues the pintail will be broken off.
The trigger switch must be released immediately after pin break occurs. Releasing the trigger switch will cause the solenoid to de-
energise and reverse the flow of pressurised oil.
Pressurised oil will now flow into the return side of the installation tool with the oil in the pull side returning to the tank.
The forward movement of the piston/collet assembly firstly ejects the installed fastener from the anvil and as the forward movement
continues, the jaw release mechanism will cause the jaws to open and release the broken off pintail, which will then be ejected.
When the piston returns to the fully forward position the pressure build up in the system will cause the Hydrapac to go into idle mode.
This keeps the installation tool in the forward position. Once the pintail has been ejected from the nose, the tool is ready for the next
installation.
Please note that with all HydraPacs there is a built in "Sleep Mode" which in effect means that the electric motor will automatically
switch off if the trigger switch is not operated for approximately 25 seconds. The HydraPac will automatically start up on depression
of the tool trigger switch.

•
Attach the correct nose assembly to tool as per instructions in the relevant nose assembly data sheet.
•
Ensure the HydraPac is not running.
•
Connect hoses and the control cord to the Hydrapac, the tool is supplied with a 0.7m hose length.
Additional hydraulic hose lengths are available to order separately as required. Refer to the table below for the available lengths
and associated part numbers.
•
Start the HydraPac. Depress and release the trigger switch a few times to almost the full stroke of the tool to circulate hydraulic
fluid. Observe action of tool. Check for fluid leaks and ensure that in the idler mode the piston is in the fully forward position.
