7. Operation
■ The base material may splinter
when a fastener is driven or frag-
ments of the cartridge strip may
fly off.
■ Flying fragments may injure parts
of the body or the eyes.
■ Wear safety goggles and a hard
hat (users and bystanders).
■ The nail or stud is driven by a car-
tridge being fired.
■ Excessive noise may damage the
hearing.
■ Wear ear protection (users and
bystanders).
■ The tool could be made ready to
fire if pressed against a part of
the body (e.g. hand)..
■ This could cause a nail to be dri-
ven into a part of the body.
■ Never press the muzzle of the tool
against parts of the body.
■ Under certain circumstances, the
tool could be made ready to fire
by pulling back the fastener guide
or the fastener by hand.
■ When in the "ready to fire" state,
a fastener could be driven into a
part of the body.
■ Never pull back the fastener guide
or fastener by hand.

Loading the tool
1. Insert the fastener (head first) until the washer is held
in the tool.
2. Load the cartridge strip (narrow end first) by insert-
ing it into the bottom of the tool grip until flush. If
the strip has been partly used, pull it through until
a live cartridge is in the chamber. (The last visible
number on the back of the cartridge strip indicates
which cartridge is next to be fired.)

Adjusting the driving power
Select a cartridge power level and power setting to suit
the application. If you cannot estimate this on the basis
of previous experience, always begin with the lowest
power.
1. Press the release button.
2. Turn the power regulation wheel to 1.
3. Drive a fastener.
4. If the fastener doesn't penetrate deeply enough,
increase the power level and repeat steps 1 to 3.
Repeat until the desired depth of penetration is
reached. Use a more powerful cartridge if neces-
sary.

Fastening with the tool
1. Press the tool firmly against the work surface at right
angles.
2. Fire the tool by pulling the trigger.
WARNING
● Never attempt to drive a fastener in an existing hole
except where recommended by Hilti, e.g. when using
the DX X-BT system.
● Never attempt to redrive the same fastener.
● Never exceed the maximum fastener driving rate.
