8. Care and maintenance
When this type of tool is used under normal operating
conditions, dirt and residues build up inside it and func-
tionally relevant parts are subject to wear. Regular inspec-
tions and maintenance are thus essential in order to
ensure reliable operation.
Recommended interval for cleaning the tool and check-
ing the condition of the piston and piston stopper:
●
At least daily when the tool is subjected to inten-
sive use.
●
After driving 5,000 fasteners, at the latest.
-WARNING-
The tool must be unloaded before carrying out care and
maintenance.
– 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-
The tool must be unloaded.
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.
-NOTE-
Check the piston for straightness by rolling it on a smooth
surface.
Never use a worn or damaged piston and do not tam-
per with or modify the piston in any way.
7. Pull out the catch before inserting the piston. Hold
the catch in this position until the piston is fully
inserted and its tip no longer projects from the tool.
8. Insert the piston stopper the right way round in the
base plate (rubber part toward the front).
9. Press the base plate and the fastener transport sys-
tem against the threaded section on the tool and
rotate it in a clockwise direction until it is screwed
on as far as it will go.
10.Turn the base plate with the fastener transport sys-
tem back to its original position over the magazine.
11.Push the magazine back until it engages with the fas-
tener transport system.
-CAUTION-
●
The tool may become hot during
operation.
●
You could burn your hands.
●
Wear protective gloves before
carrying out care and maintenance.
8.1 Care of the tool
Clean the casing of the tool at regular intervals with a
damp cloth.
-NOTE-
Do not use a spray or steam-cleaning system for clean-
ing. Never operate the tool when the ventilation slots are
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 prop-
erly. Do not operate the tool when parts are damaged or
when the controls do not operate properly. If necessary,
have the tool repaired at a Hilti service centre.
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.
