3. Definitions 3. Definitions Stak Jaks lift evenly almost over the entire surface during inflation and thanks to their construction, also maintain the shape and size of the bearing surface Bearing surface is the surface of the Stak Jak in contact with the load or the object to be lifted Controller is a device that supplies, empties and monitors the filling procedure with the air.
If the Stak Jak is stored vertically (upright) it is recommended fixing it to a surface (e.g. a wall) to protect against bending. The inflation connector should face upwards and be covered by the protective cap� It is recommended that Stak Jaks are stored in their original packaging to minimise various environmental influences on the product during storage.
• Inflate the Stak Jak until a required or maximum height, or maximum working pressure is reached. • Improper use of Stak Jaks should be avoided. MFC International Ltd assumes no responsibility for damage resulting from improper use of the product. •...
5.3. SYSTEM FOR STAK JAK INFLATION • Stak Jaks are to be infl ated solely with air, other gases should not be used. Controllers with built-in safety valves should be used for infl ation of Stak Jaks. • Never infl ate a Stak Jak without a load to more than 1 bar pressure. •...

Step 1: Position the Stak Jaks Position the Stak Jak in a defi ned and previously prepared location. Follow the rules defi ned in sections 5.1 and 5.2. Use mechanical supports for load stabilization. Fig 5�2 Step 2: Connect outlet hoses to Stak Jak Outlet hoses are of diff erent colour to prevent confusion during use.

Step 4.1: Remove the safety plug from the compressed-air cylinder Before removing the safety plug, check if the valve on the cylinder is shut-off ; to shut-off the valve turn it clockwise� Unscrew the safety plug and keep it in a safe place�...

Step 4.4: Set the pressure regulator to the required value Open the valve on the cylinder. Unscrew it completely then turn back by half a turn� The pressure gauge should indicate a value of 200 or 300 bar depending on cylinder capacity. The required working pressure is set by turning the adjusting valve.
5.3.2. WORKING WITH THE CONTROLLERS Always monitor the pressure on the respective pressure gauge, the behaviour of the Stak Jaks and the load during inflation. If the maximum pressure is exceeded the safety valve on the controller activates and relieves the pressure from the Stak Jak�...

Step 6: Dismount the pressure regulator Unscrew the locking nut on the pressure regulator and detach the regulator from the compressed- air cylinder, see Fig 5.7. Step 7: Attach the safety plug on the compressed-air cylinder, see Fig 5.5. Step 8: Disconnect the outlet hoses from the controller by pushing the hose connector towards the controller.
5.4. LIFTING PROCEDURE Before starting work, check the location where the Stak Jak is to be positioned. Remove any sharp objects such as glass fragments or other foreign particles to avoid damaging the Stak Jak. Never lift with a Stak Jak that is in contact with any sharp metal edges, nails, screws or similar that may puncture, abrade or otherwise damage the Stak Jak.
5.4.1. LIFTING WITH A SINGLE STAK JAK If only one Stak Jak is available and the gap between the ground and the object to be lifted exceeds 70mm, build a firm and sufficiently high support to a point that just allows enough space to insert an uninflated Stak Jak.
5.4.2. LIFTING WITH SEVERAL STAK JAKS, INCREASING THE LIFTING CAPACITY Lifting capacity can be increased by positioning two Stak Jaks side by side and simultaneously inflating, see Fig 5.18. The new capacity is double that of a single Stak Jak. Example: The capacity of combined Stak Jaks KSM17 and KSM17 side by side and simultaneously inflated amounts to 34 t, i.e.
5.4.2.1 LIFTING USING TWO OR THREE STAK JAKS A MAXIMUM of THREE Stak Jaks may be combined to increase lifting height. If lifting with two or three Stak Jaks to achieve a higher lift, only use Stak Jaks of the same dimensions. When combining Stak Jaks to increase lifting height, place the Stak Jaks on top of each other and make sure that all connectors are facing forwards, see Fig 5.20.
5.4.3. LIFTING LOADS OF UNUSUAL SHAPE 5.4.3.1. LIFTING OF PIPES AND PROFILES A problem arises when the load does not rest over the entire lifting surface of the Stak Jak. Moreover, the Stak Jak may become damaged if it bends or is overloaded with angular, jagged or sharp-edged loads.
5.4.3.3. USING A STAK JAK TO SEPARATE OR MOVE AN OBJECT Stak Jaks can be used for separating and moving objects horizontally. Position one face of the Stak Jak against a bar, a pillar or another firm and rigid object; position the opposite face against the object to be moved.
5.5. UNEXPECTED SITUATIONS If the Stak Jak, hoses or any other components of the lifting system suff er damage which may compromise safety at work, immediately interrupt work and replace the damaged component. Never use Stak Jaks and hoses that exhibit cracks, bulges, unusual deformations or similar.

5.7. DISPOSAL OF WASTE MATERIAL A damaged or unserviceable product or a product whose service life has expired should be withdrawn from the use. As Stak Jaks are designated as recyclable, waste classification according to valid local regulations applies� 6. Maintenance and Cleaning 6.
6.2.1.1 REPLACING THE STAK JAK INFLATION CONNECTOR The following items are required when replacing a Stak Jak inflation connector: • Spare Type 25 male connector (male thread) • 2 x 17mm spanner • Liquid thread sealant Using two 17mm spanners, unscrew the damaged inflation connector from the Stak Jak as shown in Fig 6.1.
6.2.3. MAINTENANCE OF THE CONTROLLER AFTER USE Controllers should be cleaned and maintained in compliance with the relevant instructions supplied. 6.3. PREVENTIVE MAINTENANCE Preventive maintenance includes routine inspection of Stak Jaks and associated equipment for lifting, performance of tests and replacement of damaged parts. The enclosed check-up lists can offer assistance when carrying out preventive maintenance.
