The tool must be cycled and loaded before driving each
fastener.
1. Grip the fastener guide between the thumb and
en
forefinger and pull it forward in the main axis of the
tool as far as it will go.
2. Insert an unused cartridge in the cartridge chamber.
NOTE Insert the cartridge in the tool gently. Do not
press it in!
3. Then pull the fastener guide all the way back to its
original position.
This movement returns the piston to its original
position, ready to drive a fastener.
4. Push the nail, head first, into the nose of the tool
from the front until it is held in place in the tool by
the washer on the nail.
NOTE If the cycling action (i.e. pulling out, pushing
back in) is stiff, this indicates that the tool needs to
be cleaned. Service the tool! see section 9.3
The tool is then ready to drive the next fastener.

1. Select the cartridge power level according to the
application to be carried out.

9 Care and maintenance

CAUTION
When this type of tool is used under normal operating
conditions, dirt and residues build up inside the tool and
functionally relevant parts are also subject to wear. Reg-
ular inspections and maintenance are thus essential
in order to ensure reliable operation. We recommend
that the tool is cleaned and the condition of the pis-
ton checked at least daily when the tool is subjected
to intensive use, and at the latest after driving 3,000
fasteners.
WARNING
Make sure there is no cartridge in the tool before
carrying out maintenance or repairs. Make sure there
is no fastener in the fastener guide.
CAUTION
The tool may get hot during use. You could burn your
hands. Do not dismantle the tool while it is hot. Allow
the tool to cool down.

WARNING
Never attempt to remove a cartridge from the cart-
ridge chamber by prying it out from behind with a
pointed or sharp object.
As soon as you have finished the work, check to ensure
that there is no cartridge or nail in the tool. If the tool is
still loaded after finishing the work, remove the cartridge
and the nail from the tool.
NOTE
If a cartridge case remains stuck in the cartridge chamber,
disassemble the tool as described in section 9.3.1 and
use the ramrod to push the cartridge case out of the
cartridge chamber from the front.
9.1 Care of the tool
WARNING
Do not use a spray or steam/water jet system for
cleaning. Never operate the tool when the ventilation
slots are blocked. Do not permit foreign objects to
enter the interior of the tool.
Clean the outside of the tool at regular intervals with a
slightly damp cloth.
9.2 Maintenance
Check all external parts of the tool for damage at regular
intervals and check that all controls operate faultlessly.
Do not operate the tool if parts are damaged or when the
controls do not function faultlessly. If necessary, the tool
should be repaired by Hilti Service.
Use the tool only with the recommended cartridges. Use
of the wrong cartridges or use of excessively high power
settings may lead to premature failure of parts of the tool.
WARNING
Dirt and residues in DX tools contain substances that
may be hazardous to your health. Do not inhale dust /
or dirt from cleaning. Keep the dust or dirt away from
foodstuffs. Wash your hands after cleaning the tool.
If you cannot estimate this on the basis of previous
experience, always begin with the lowest power.
Select the lowest power level according to the color
code.
Drive a nail.
If the nail does not penetrate deeply enough, use a
more powerful cartridge.
Press the tool against the working surface at right
angles.
Drive the fastener by pulling the trigger.
