3.2 Intended use
The product described is a gas-actuated fastening tool (“fastening tool”). It is designed to drive suitable
fasteners into concrete, steel, sand-lime block, concrete-block masonry, rendered masonry and other
materials suitable for use of the direct fastening technique.
The fastening tool is for hand-held use or use with the pole tool extension (accessory) only.
3.3 Items supplied
Gas-actuated fastening tool with fastener guide, toolbox, operating instructions.
Other system products approved for use with this product can be found at your local Hilti Center or online
at: www.hilti.group
3.4 Fastener guide
The fastener guide holds the studs or, respectively, guides the nails and, when the tool is fired, thus directs the
fasteners into the supporting material at the desired position. Application-specific fastener guides (IF or ME)
are available for the GX 3 and GX 3-ME fastening tools (see type identification plate for exact designation).
3.5 Fasteners
Two types of fastener can be driven by the fastening tool: nails and threaded studs. Additional fastening
components, which can be inserted in the fastener guide, are also available for various applications.
3.6 Slider for fastener driving depth adjustment and for releasing the fastener guide
The slider can be used to reduce the depth to which the fastener is driven. In the EJECT position, it releases
the fastener guide for removal.
Status Meaning
+
• Standard fastener driving depth

• Reduced fastener driving depth
EJECT
• Fastener guide release
3.7 RESET button
After driving a fastener, under certain circumstances, the fastener guide may not return to its outset position.
This is caused by the piston being incorrectly positioned. The incorrect piston position can be remedied by
pressing the RESET button.
Status Meaning
RESET button projects from the tool casing. Its
white edge is visible.
• Piston position is incorrect
RESET button is flush with the tool casing.
• Piston position is correct
3.8 Support leg
On an even working surface, the support leg makes it easier to hold the fastening tool perpendicular as
attention then only has to be paid to lateral alignment. On an uneven or undulating surface it may be necessary
to remove the support leg in order to allow the fastener guide to be held perpendicular to the working surface.
