General information 2.1 Signal words -WARNINGThe word WARNING is used to draw attention to a potentially dangerous situation which could lead to severe personal injury or death. -CAUTIONThe word CAUTION is used to draw attention to a potentially dangerous situation which could lead to minor personal injury or damage to the equipment or other property. -NOTEUsed to draw attention to an instruction or other useful information. 2.2 Pictograms Warning signs The numbers refer to the illustrations.
The drop-firing safety device 2 is the result of coupling the firing mechanism with the cocking movement. This is designed to help prevent the Hilti DX tool from firing when it is dropped onto a hard surface, no matter at which angle the impact occurs. 2 4 3 5 en The trigger safety device 3 ensures that the cartridge cannot be fired simply by pulling the trigger only. The tool can be fired only when fully depressed.
Prevention of misuse: – When the piston tip is worn or damaged, never try to grind the tip in order to re-use the piston. This may cause serious damage to the tool and will adversely affect fastening quality. – Please refer to the table below for the right fastener guide/piston/fastener combination. Use of the wrong combination may result in damage to the tool.

7.1 Fastening guidelines -NOTEThese application recommendations must always be observed. For more specific information, refer to the Hilti Fastening Technology Manual, which is available from your local Hilti organisation. 7.1.1 Driving threaded studs 1. Mark the point where the stud is to be driven. 2. Drill a hole. Continue drilling until the drill bit cuts a bright ring around the hole. 3. Keep the hole clean (clean away any debris, dirt, water or other liquids). 4.
8. Care and maintenance en When this type of tool is used under normal operating conditions, dirt and residues build up inside the tool and functionally relevant parts are also subject to wear. Regular inspections and maintenance are thus essential in order to achieve reliable operation. We recommend that the tool is cleaned and the piston and piston brake are checked at least weekly when the tool is subjected to intensive use, and at the latest after driving 2,000 fasteners. 8.
3. Fit the complete unit into the tool so that the marks on the piston guide and on the metal housing are in alignment. 4. Press in the piston stops when the piston guide has been inserted far enough for the stops to fit into the openings at the side of the piston guide. 5. Release the black housing and screw it on to the tool (only 1–2 turns). 6. Push in the piston as far as it will go. The piston can be inserted only before the black housing is screwed on fully (before the final turn).
9. Troubleshooting en Fault Possible cause Remedy Cartridge not transported ■ Damaged cartridge strip ■ Carbon build-up ■ Cartridge strip cannot be removed ■ Tool damaged If the problem persists: ■ Contact Hilti Repair Centre ■ Tool overheated because of high ■ Let the tool cool down and then setting rate ■ Tool damaged -WARNINGNever attempt to pry a cartridge from the magazine strip or tool.
Fault Possible cause Remedy The operator notices: ■ increased contact pressure ■ increased trigger force ■ power regulation stiff to adjust ■ cartridge strip is difficult to remove ■ Carbon build-up ■ Clean the tool ■ Check that the correct cartridges Threaded studs driven to different depths or sealing washer pressure/contact not constant ■ Hole not deep enough ■ Drill to correct depth ■ Piston broken or damaged ■ Fastener guide damaged ■ Damaged protective cover ■ Tool misfires ■ Replace the pis
en Fault Possible cause Remedy The thread on the stud is damaged ■ Fastener guide damaged ■ Replace the fastener guide. Stud doesn’t hold in the base material ■ Steel base material too thin ■ Drive studs only on steel base (< 8 mm) ■ Hole damaged or previously used ■ Driving power too low ■ Hole not deep enough ■ Drill new hole. ■ Increase driving power.
10. Disposal Most of the materials from which Hilti power actuated tools are manufactured can be recycled. The materials must be correctly separated before they can be recycled. In many countries, Hilti has already made arrangements for taking back your old powder actuated tools for recycling. Please ask your Hilti customer service department or Hilti sales representative for further information.
