9. Care and maintenance

CAUTION
en
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 tool is cleaned and the
condition of the piston checked 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. Check
to ensure that no fastener is present in the fastener
guide before carrying out maintenance or repairs.
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.

9.1 Care of the tool

Clean the outside of the tool at regular intervals with
a slightly damp cloth.
WARNING
Do not clean with a spray or pressure washer. Do not
permit foreign objects to enter the interior of the tool.
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 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 /
or dirt from cleaning. Keep the dust or dirt away from

foodstuffs. Wash your hands after cleaning the tool.
Never use grease for the maintenance/lubrication of
parts of the tool. This may lead to malfunctions. Use
only Hilti lubricant spray or a product of equivalent
quality.

9.3 Servicing the tool

Service the tool if fastener driving power is found
to be inconsistent, if cartridges misfire or if parts
of the tool no longer move or operate smoothly and
easily. In other words, servicing is necessary when it
takes more force to press the tool against the work
surface, when trigger resistance increases, when the
power regulating wheel begins to stick, when the
cartridge strip is difficult to remove or the cycling
action becomes increasingly stiff.
9.3.1 Disassembling the tool 8
CAUTION
Forcing the spring clip into place may cause it to
jump off with considerable energy. Take care to avoid
injuring yourself or others. Hold the assembly with
its back facing downwards.
1. Pivot the catch out by turning the ring through
45 degrees.
NOTE If the catch sticks, a nail can be used to
help release it.
2. Allow the assembly to slide out of the tool.
NOTE If the assembly sticks in place it can be
released by pulling with a jerk.
3. Remove the spring clip. Use a suitable tool for
this purpose (e.g. screwdriver or nail).
4. Pull the base plate, complete with the fastener
guide, off the piston guide.
5. Pull the piston out of the piston guide.
6. Allow the fastener guide to slide out of the base
plate toward the rear.
NOTE If the parts of the tool tend to stick due
to carbon build-up, use the piston to push the
fastener guide out of the base plate from the
front.
