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.
Check the piston and the buffer daily when the tool is subjected to intensive use, or at the very
least, before the end of the recommended regular cleaning interval of 2,500 - 3,000 fastenings.
The inspections, service intervals and cleaning intervals are based on typical tool use. If you find
that the tool is not functioning correctly before a scheduled interval is reached, service the tool
immediately.
