7.1 Loading the tool
1. Push the nail or stud into the front end of the tool until
it is held by the washer.
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 an
unused cartridge is in the chamber. (The last visible
number on the back of the cartridge strip indicates
which cartridge is next to be fired.)

7.2 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 nail or threaded stud.
4. If the fastener doesn't penetrate deeply enough,
increase the driving power by turning the power reg-
ulation wheel. Use a more powerful cartridge if nec-
essary.
aa
7.3 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 Kwik system.
● Never attempt to redrive the same fastener.
● Never exceed the maximum fastener driving rate.
aa
7.4 Reloading the tool
Ensure that no cartridge strip or fastener is loaded in the
tool. Remove the cartridge strip by pulling it upwards
out of the tool and remove the fastener from the fastener
guide.

8. Care and maintenance

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.
Regular inspections and maintenance are thus essen-
tial in order to ensure reliable operation. We recom-
mend that the tool is cleaned and the piston and piston
brake are checked at least weekly when the tool is sub-
jected to intensive use, and at the latest after driving
10,000 fasteners.
8.1 Care of the tool
The outer casing of the tool is manufactured from
impact-resistant plastic. The grip comprises a synthetic
rubber section.
The ventilation slots must be unobstructed and kept
clean at all times. Do not permit foreign objects to enter
the interior of the tool. Use a slightly damp cloth to
clean the outside of the tool at regular intervals. Do not
use a spray or steam-cleaning system for cleaning.
8.2 Maintenance
Check all external parts of the tool for damage at reg-
ular intervals and check that all controls operate prop-
erly. Do not operate the tool when parts are damaged
or when the controls do not operate properly. If nec-
essary, have the tool repaired at a Hilti service centre.
■ The tool can get hot while oper-
ating.
■ You could burn your hands.
■ Do not disassemble the tool while
it is hot. Let the tool cool down.
Servicing the tool
The tool should be serviced if:
1. Cartridges misfire
2. Fastener driving power is inconsistent
3. If you notice that:
● contact pressure increases,
● trigger force increases,
● power regulation is difficult to adjust (stiff),
● the cartridge strip is difficult to remove.
CAUTION while cleaning the tool:
● Never use grease for maintenance/lubrication of tool
parts. This may strongly affect the functionality of the
tool. Use only Hilti spray or such of equivalent quality.
● Dirt from DX tool contains substances that could be
endangering your health.
– Do not breath in the dust from cleaning
– Keep dust away from food
– Wash your hands after cleaning the tool
