7 Troubleshooting
WARNING
Risk of explosion! Cartridges may fire (explode) if handled improperly.
▶
Do not use force to remove cartridges from the fastening tool or the magazine strip.
WARNING
Hazard due to hot surfaces! The fastening tool can become hot in use.
▶
Wear protective gloves.
7.1 Cartridge does not fire when fastening tool is hot (above design-base maximum operating
temperature)
1. Keep the fastening tool pressed against the work surface for at least 10 seconds and trigger the fastening
tool again.
2. If the cartridge still does not fire, lift the fastening tool away from the work surface.
▶
Be sure not to point it toward yourself or other persons!
3. Immediately pull the cartridge strip out of the fastening tool.
If the cartridge strip cannot be removed, allow the fastening tool to cool down sufficiently under
observation. Make sure that the fastening tool is not pointed at yourself or other persons while it
is cooling down.
4. Move the cartridge to a safe location.
5. Dispose of the cartridges that have not fired.
▶
Comply with the locally applicable disposal regulations.
6. Allow the fastening tool to cool down and resume work with a new cartridge strip.
7.2 The cartridge does not fire when the fastening tool is at operating temperature
1. Stop using the tool immediately.
2. Unload and dismantle the fastening tool.
3. Check that you are using the correct combination of fastener guides, piston, fasteners and cartridge.
4. Check the buffer, piston and fastener guides for wear; replace the components as necessary.
5. Clean the fastening tool.
▶
If the problem persists after the measures described above have been taken, further use of the
fastening tool is not permissible.
▶
Have the fastening tool checked and, if necessary, repaired by Hilti Service.
Dirt and residues build up in the tool under normal operating conditions and functional parts are
also subject to wear.
Service the tool at regular intervals. Check the piston and buffer daily if the fastening tool is used
intensively, or at the latest after every 2500 to 3000 fasteners. The interval corresponds to the
regular cleaning cycle of the fastening tool. The service and cleaning cycles are based on typical
tool use.
The fastener counter shows how many fasteners have been driven since the cleaning indicator
was last reset. One segment stands for 500 fasteners driven.
When 30,000 fasteners have been driven, have the tool serviced by Hilti Service.
