Push the cartridge strip, narrow end first, into the grip of the tool from below until the full length of the cartridge strip is inside the tool. If you wish to use a cartridge strip in which some of the cartridges have already been used, start pulling the strip up and out the top of the tool by hand until the first unused cartridge is in place in the cartridge chamber.
5.5 Driving fasteners with the single-fastener tool 1. Position the tool. 2. Hold the tool perpendicular to the working surface and then press it against the surface. 3. Press the trigger to drive the fastener. 5.6 Driving fasteners with the magazine tool 1. Position the tool. 2. Hold the tool perpendicular to the working surface and then press it against the surface. 3. Press the trigger to drive the fastener. 5.7 Unloading the single-fastener tool 1. Pull the cartridges out of the tool.
2. Pull the fastener out of the tool. 5.8 Unloading the magazine tool 1. Pull the cartridges out of the tool. 2. Pull the magazine cover down and remove the fastener strip. 5.9 Switching Bluetooth on and off Press and hold the pushbutton for 1-2 seconds to switch on Bluetooth. ▶ Note Bluetooth switches itself off automatically after 2 minutes. 5.10 Resetting the cleaning indicator Press and hold the pushbutton for 10-12 seconds to reset the cleaning indicator.
◁ Have the tool checked and, if necessary, repaired by Hilti Service. Note Dirt and residues build up in the tool under normal operating conditions and functional parts are also subject to wear. Carry out regular inspections and servicing. Servicing must be carried out after 30,000 fasteners have been driven. Clean the tool after every 2,500 - 3,000 fastenings. The fastener counter shows how many fasteners have been driven since the cleaning indicator was last reset. One bar stands for 500 fasteners.
◁ ◁ ◁ ◁ If the trigger resistance increases. If the power regulation wheel is stiff. If the cartridge strip is difficult to remove. If the maintenance indicator shows that a tool service is necessary. 6.4 Dismantling the single-fastener tool 1. 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. 2.
6.6 Checking the piston and buffer for wear WARNING Checking the buffer and piston for wear Check the buffer and piston for wear. ▶ Check the buffer and piston for wear. Do not tamper with or modify the piston. 1. The piston must be replaced in the following cases: ◁ The piston is broken. ◁ The piston is badly worn or chipped (e.g. a 90° segment broken away). ◁ The piston rings are cracked or missing. ◁ The piston is bent (check by rolling the piston on a smooth, flat surface). 2.
6.8 Cleaning and lubricating the single-fastener tool 1. Spray the piston rings lightly with oil and then use the flat brush to clean them using the flat brush until the rings are free to move. 2. Use the flat brush to clean the thread on the fastener guide. 3. Use the large round brush to clean the inside of the housing. 4. Dismantle the exhaust gas piston return unit. 5. Clean the exhaust gas piston return unit. 6. Spray the cleaned parts with the supplied Hilti lubricant spray.
6.9 Cleaning and lubricating the magazine tool 1. Spray the piston rings lightly with oil and then use the flat brush to clean them using the flat brush until the rings are free to move. 2. Use the flat brush to clean the thread on the fastener guide. 3. Use the large round brush to clean the inside of the housing. 4. Dismantle the exhaust gas piston return unit. 5. Clean the exhaust gas piston return unit. 6. Spray the cleaned parts with the supplied Hilti lubricant spray.
6.10 Assembling the single-fastener tool 1. 2. 3. 4. 5. Check whether there is a cartridge in the tool, and remove it if there is. Fit the exhaust gas piston return unit. Fit the piston. Fit the buffer onto the fastener guide. Screw on the fastener guide. 6.11 Assembling the magazine tool 1. 2. 3. 4. 5. Check whether there is a cartridge in the tool, and remove it if there is. Fit the exhaust gas piston return unit. Fit the piston. Fit the buffer onto the fastener guide. Screw on the fastener guide.
7 Troubleshooting 7.1 Problems with the tool Malfunction Possible cause The fastener is too short. ▶ Driving power is too high. ▶ ▶ ▶ ▶ Higher force required to press Build-up of combustion residues. the tool against the surface. Stiff movement of power regulation wheel. ▶ The fastener has no washer. The piston gets stuck in the base material. Trigger resistance increases. Action to be taken Build-up of combustion residues. The exhaust gas piston return unit jams. ▶ Service the tool.
Malfunction The tool cannot be fired. The piston jams in the fastener guide. Possible cause Nails in the magazine are not correctly positioned. Action to be taken ▶ Reload the tool. The piston and/or buffer are damaged. ▶ Plastic fragments in the magazine. Unscrew the magazine, check the piston and buffer and replace if necessary. ▶ Use of excessively high driving power on steel. ▶ Reduce the driving power. ▶ Avoid firing the tool without a fastener loaded.
Malfunction Possible cause A rebar is located just below the concrete surface. Action to be taken ▶ ▶ ▶ The fastener is not driven flush. Concrete spalling. Hard surface (steel, concrete). ▶ Hard/old concrete. ▶ Driving threaded studs: Spall stop: X-SS... Hard aggregates in concrete ▶ ▶ Use a more powerful cartridge. Use the single-fastener tool instead of the magazine tool. Driving power is too high. ▶ Reduce driving power (adjust the power regulating wheel). Use a less powerful cartridge.
Malfunction Possible cause Driving power is too low. Action to be taken ▶ ▶ Fastener breakage. The application limits have been exceeded (very hard material). ▶ ▶ ▶ Driving power is too high. ▶ ▶ ▶ ▶ Driving power is too high. ▶ ▶ ▶ ▶ The head of the fastener perforates the fastened material. Increase driving power (adjust power regulating wheel). Use a more powerful cartridge. Use a nail with a higher application limit. Use the single-fastener tool instead of the magazine tool.
Malfunction A cartridge detaches itself from the cartridge strip. Possible cause The fastener driving rate is too high. Build-up of combustion residues. Action to be taken ▶ ▶ Stop using the tool immediately. Remove the cartridge strip and allow the tool to cool. ▶ Service the tool. The cartridge strip cannot be removed. 7.5 Other malfunctions If the trouble you are experiencing is not listed in this table or you are unable to remedy the problem by yourself, please contact Hilti Service.
