The tool can be made ready to fire by pressing the nosepiece against a part of the body (e.g. a hand). When the tool is ready to fire, fasteners or the piston could be driven inadvertently into parts of the body. Never press the tool against parts of the body.
The material may splinter or fragments of the magazine strip may fly off when the fastener is driven. The user of the tool and other persons in the immediate vicinity must wear suitable eye protection and a hard hat. Splintering material presents a risk of injury to the eyes and body.
The fastener driving action is initiated by ignition of a propellant charge. The user of the tool and other persons in the immediate vicinity must wear ear protectors. Exposure to noise can cause hearing loss.
Never redrive a fastener. This may cause the fastener to break and the tool may jam.
Never drive fasteners into existing holes unless this is recommended by Hilti (e.g. DX‑Kwik).
If the tool has overheated, allow it to cool down. Do not exceed the recommended fastener driving rate.
If a cartridge fails to fire or misfires, always proceed as follows:
Keep the nose of the tool pressed at right angles against the working surface for 30 seconds.
If the cartridge still fails to fire, withdraw the tool from the working surface, taking care to avoid pointing it toward your body or toward bystanders.
Load the next cartridge on the strip by cycling the tool. Use up the remaining cartridges on the strip and remove the used cartridge strip from the tool. The (partly) used cartridge strip must then be disposed of appropriately to prevent further use or misuse of any unfired cartridges.

Always observe the safety rules listed in the operating instructions.
Fig.5
Do not use a swinging movement to cycle the tool (piston return and cartridge transport). The swinging movement may lead to injury or cause damage to the tool.
NOTE: If the cycling action (i.e. pulling out, pushing back in) is stiff, this indicates that the tool needs to be cleaned. Service the tool! (see "Servicing the tool" section).
Fig.6
Check that there is no cartridge strip or fastener in the tool.
If there is a cartridge strip or fastener in the tool, pull the cartridge strip up out of the tool by hand from above and remove the fastener from the fastener guide.
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 ensure reliable operation. We recommend that the tool is cleaned and the condition of the piston checked at least daily when the tool is subjected to intensive use, and at the latest after driving 3,000 fasteners.
All cartridges must be removed from the tool. Check to ensure that no fastener is present in the fastener guide before carrying out maintenance or repairs.
The tool may get hot during use. You could burn your hands. Wear protective gloves when carrying out care and maintenance. Allow the tool to cool down.
Clean the outside of the tool at regular intervals with a slightly damp cloth.
Do not clean with a spray or pressure washer. Do not permit foreign objects to enter the interior of the tool.
Check all external parts of the tool for damage at regular intervals and check that all controls operate faultlessly. Do not operate the tool if parts are damaged or when the controls do not function faultlessly. If necessary, the tool should be repaired by Hilti Service.
Use the tool only with the recommended cartridges and power settings. Use of the wrong cartridges or use of excessively high power settings may lead to premature failure of parts of the tool.
Dirt and residues in DX tools contain substances that may be hazardous to your health. Do not inhale dust / or dirt from cleaning. Keep the dust or dirt away from foodstuffs. Wash your hands after cleaning the tool. Never use grease for the maintenance/lubrication of parts of the tool. This may lead to malfunctions. Use only Hilti lubricant spray or a product of comparable quality.
Service the tool if fastener driving power is found to be inconsistent, if cartridges misfire or if parts of the tool no longer move or operate smoothly and easily. In other words, the required contact pressure increases, trigger resistance increases, the cartridge magazine strip can only be removed with a degree of difficulty or the cycling action becomes stiff.
Fig.7
When removing the spring clip from the base plate, the spring clip may jump off the base plate very suddenly. Take care to avoid injury to yourself or other persons. Hold the base plate so that the spring clip, if it jumps off, tends to jump towards the floor.
NOTE: If the parts of the tool tend to stick due to carbon build-up, use the piston to push the fastener guide out of the base plate from the front.
NOTE: Never use a worn or damaged piston and do not tamper with or modify the piston.
Replace the piston if:
Replace the fastener guide if the tubular section is damaged (e.g. bent, widened, cracked or broken).
Replace the spring clip if it is badly worn, bent or widened.
Clean the tool at least once a week or, respectively, immediately after each period of heavy use (after driving approx. 3,000 nails).
Use the appropriate brushes to clean the individual parts:
Spray the cleaned parts lightly with the Hilti lubricant spray supplied. Use only Hilti lubricant spray or a product of comparable quality.
Fig.12
NOTE: Handle the small parts carefully. They could get lost.
After carrying out care and maintenance, check that all protective and safety devices are fitted and that they function faultlessly.
NOTE: The tool can be checked, as follows, to determine whether it is ready to fire: Press the nose of the unloaded tool (i.e. no cartridges or fastener in the tool) firmly against a hard surface and pull the trigger. A clearly heard click from the trigger mechanism indicates that the tool was ready to fire.
The tool must be unloaded before taking any steps to remedy faults.
