obstructed. 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 regu-
lar intervals and check that all controls operate properly.
Do not operate the tool when parts are damaged or when
the controls do not operate properly. If necessary, have
en
the tool repaired at a Hilti service center.
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- when cleaning:
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 comparable
quality.
The residues deposited inside DX tools contain sub-
stances that may be injurious to your health:
– Do not inhale any dust or dirt while cleaning.
– Keep the dust or dirt away from foodstuffs.
– Wash your hands after cleaning the tool.
8.2.1 Checking and replacing the piston and piston
stopper
-NOTE-
– If the tool is used incorrectly (e.g. no fastener loaded
in the tool before firing or the fastener is driven into
unsupported sheet metal), the piston may become
jammed against the piston stopper. Should the piston
and piston stopper become fully seized in this way,
these parts have reached the end of their life. The tool
cannot be cycled when in this status.
– The condition of the piston and piston stopper must
be checked at regular intervals and at least daily.
-WARNING-
All cartridges must be removed from the tool.
1. Stand the tool on its grip (upside down).
2. Press the red button above the magazine and allow
the fastener strips to slide out of the magazine.
-CAUTION-
Parts of the tool may become very hot after a period of
use. Protective gloves must be worn if the following
maintenance procedure is carried out before the tool
has been allowed to cool down.
3. Unscrew the base plate with the fastener transport
system in a counter-clockwise direction until it is
released from the tool. Lift the base plate and fas-
tener transport system away from the tool.
4. Pull the piston out of the piston guide.
5. Also pull the piston stopper out of the base plate
(with the aid of the piston, if necessary).
6. Check the piston and piston stopper for damage. If
signs of damage are found or the piston is jammed
against the piston stopper, the piston and piston
stopper must be replaced.
