10.2 Cleaning the fastening tool
Note
The fastening tool must be cleaned and serviced regularly. We recommend that a cleaning service is
carried out, at the latest, after driving 25,000 fasteners.
▶ Clean the fastening tool, or have it cleaned, if malfunctions such as misfiring occur increasingly.
▶ For cleaning, use the cleaning set (available as an accessory) and observe the illustrated cleaning
instructions enclosed with it.
10.3 Maintenance
▶ To help ensure safe and reliable operation, use only genuine Hilti spare parts and consumables. Spare
parts, consumables and accessories approved by Hilti for use with the product can be found at your
local Hilti Center or online at: www.hilti.group.
▶ Check all external parts of the fastening tool for signs of damage at regular intervals and make sure that
all the controls function correctly.
▶ Do not use the fastening tool if parts are damaged or if the controls do not function correctly.
▶ Have a defective fastening tool repaired by Hilti Service.
10.4 Checks after care and maintenance work
