Description
Do not press the nosepiece of the fastening tool against any part of the
body!
Pressing the nosepiece against a part of the body (a hand, for example) can
make the fastening tool ready to fire. As a result, there would be the risk of a
fastener being fired into a part of the body.
Do not pull back the magazine or other fastener guides by hand!
Pulling the magazine back by hand can make the fastening tool ready to fire. As
a result, there would be the risk of a fastener being fired into a part of the body.
6.1 Driving fasteners 7
CAUTION
Risk of injury! If the tool is extremely hot (see service indicator display) cartridges may explode due to the
effect of the heat, causing flying fragments.
▶
Remove the cartridges from the tool immediately before breaks between working.
▶
If the cartridges cannot be removed from the tool, lay the tool down and make sure that all persons keep
a safe distance away from the tool (3 meters) until the pointer on the temperature indicator has moved all
the way to the left. Notify Hilti Service immediately.
1. Press the tool fully against the working surface at right angles.
2. Press the trigger buttons on the grip.
If the tool does not fire, check that a cartridge strip has been loaded and that there are enough
fasteners in the magazine.
The fasteners are not transported when the magazine contains less than 15 fasteners. You must
first insert additional nail strips in the magazine.
3. Position the tool at the point where the next fastener is to be driven and repeat the steps described. In
doing so, observe the information shown in the display. → page 6
Nail stand-off should be checked immediately after driving the first fasteners and subsequently at
regular intervals so that the driving power of the tool can be set to the right value in order to ensure
that fasteners are driven correctly.
6.2 Checking the nail stand-off
1. Use the test gauge to check the nail stand-off.
Result 1 / 3
• Nail stand-off is within the required range.
The tool power setting is incorrect. The test is
complete.
