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 'O' Ring type cushion to push the follower and jaws forward. If a Hydraloc pin has been 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 will eject the installed fastener from the anvil and as the forward movement
continues, the jaw release mechanism will partly open the jaws to allow the next fastener to be inserted into the nose.
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.
Please note that with all electric 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 10 seconds. The Hydrapac will automatically start up on depression of
the tool trigger switch. (The diesel Hydrapac does not have a "Sleep Mode".)

•
Attach the proper nose assembly to tool per instructions on the nose assembly data sheet.
•
Ensure the Hydrapac is not running.
•
Connect hoses and the control cord to the Hydrapac.
•
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.

To install a Hydraloc Fastener
•
Check work and remove excessive gap. (Gap is the space between components of the Joint. Gap is excessive if not enough pintail
sticks through the collar for the nose assembly jaws to grab onto.)
•
Put Hydraloc pin into hole.
•
Slide Hydraloc collar over pin. (The bevelled end of the collar must be towards the nose assembly and tool.)
•
Push nose assembly onto pin until the nose assembly anvil stops against the collar. Tool and nose assembly must be held at right
angles (90°) to the work.
•
Depress tool trigger switch to start installation cycle.
•
When the forward motion of the nose assembly anvil stops and the pintail breaks off, release the switch. The tool will go into its return
stroke and push off the installed fastener. At the end of the return stroke the jaws will partially release the expended pintail which can
then be pushed through the jaws with the next installation and then ejected through the rear of the tool.
•
Once the installed fastener been ejected, the tool and nose assembly is ready for the next installation.
DO NOT ATTEMPT TO BREAK OFF A PINTAIL WITHOUT THE INSTALLATION OF A COLLAR AS THIS WILL CAUSE THE
UNSECURED PORTION OF THE HYDRALOC PIN TO EJECT FROM THE NOSE AT A HIGH SPEED AND FORCE.
