7.9.2 Inserting the cartridge strip
NOTE
Use blue cartridges for best results when fastening

commended cartridges, please refer to the applicable

cartridge strip guideway on the side of the tool.

8. 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. Regular inspections and maintenance are
thus essential in order to ensure reliable operation.
We recommend that the piston and piston brake are
checked and inspected at least daily when the tool
is subjected to intensive use, and at the latest after
driving 3,000 fasteners.
WARNING
All cartridges must be removed from the tool. All
nails must be removed from the nail magazine or
the fastener guide.
CAUTION
The tool may get hot during use. You could burn your
hands. Wear protective gloves when carrying out
care and maintenance. Allow the tool to cool down.

fastener guide 18
1. Drill through the profile metal sheet and into the
concrete with the step drill bit.
2. Guide the tip of the fastener projecting from the
fastener guide into the previously drilled hole and
press the tool at right angles against the working
surface.
3. Drive the fastener by pulling the trigger.
4. Prepare the tool for driving the next fastener by
pushing the cycling grip back toward the rear of
the tool and then forward to its original position.
7.9.4 Checking and adjusting fastener driving
depth 3 6
NOTE
Fastener driving depth can be adjusted by turning
the power regulation wheel on the tool. (setting 1 =
minimum; setting 4 = maximum)
Check the nail stand-off and power setting in ac-
cordance with section 7.2.5 "Checking and adjusting
fastener driving depth".
8.1 Care of the tool
Clean the outside of the tool at regular intervals with
a slightly damp cloth.
NOTE
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.
8.2 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 dam-
aged 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
and power settings. Use of the wrong cartridges or
use of excessively high power settings may lead to
premature failure of parts of the tool.
CAUTION
Dirt and residues in DX tools contain substances that
may be hazardous to your health. Do not inhale dust /
