Care And Maintenance - Hilti DX 35 Operating Instructions Manual

If the cartridge still fails to fire, withdraw the tool from the
working surface, taking care to avoid pointing it toward
your body or toward bystanders.
Load the next cartridge on the strip by cycling the tool.
Use up the remaining cartridges on the strip and remove
the used cartridge strip from the tool. The (partly) used
cartridge strip must then be disposed of appropriately to
prevent further use or misuse of any unfired cartridges.

8.2 Loading the tool 2
1. Push the nail, head first, into the nose of the tool
from the front until it is held in place in the tool by
the washer on the nail.
2. Push the cartridge strip, narrow end first, into the
grip of the tool from below until the full length of the
cartridge strip is inside the grip.
3. If you wish to use a partly-used cartridge strip, pull
the strip upwards by hand out of the tool slightly until
the first unused cartridge is in place in the cartridge
chamber.
8.3 Selecting the cartridge
1. Select the cartridge power level according to the
application to be carried out.
2. If you cannot estimate this on the basis of previous
experience, always begin with the lowest power.
Select the weakest cartridge color and make a trial
fastener placement.
3. Drive a nail.
If the nail is not driven in deeply enough, try using a
heavier cartridge.

9 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. Reg-
ular inspections and maintenance are thus essential
in order to ensure reliable operation. We recommend
that the tool is cleaned and the condition of the pis-
ton 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.

8.4 Driving a fastener 3
WARNING
Always observe the safety rules listed in the operating
instructions.
1. Press the tool against the working surface at right
angles.
2. Drive the fastener by pulling the trigger.
8.5 Cycle the tool. 4
NOTE
If the cycling action (i.e. pulling out, pushing back in)
is stiff, this indicates that the tool needs to be cleaned.
Service the tool! (see section 9.3).
1. After driving a fastener, grip the collar at the nose of
the tool between the thumb and forefinger.
2. Pull the nose unit forward in the main axis of the tool
as far as it will go.
3. Then pull the fastener guide all the way back to its
original position.
This movement brings the piston back to its starting
position and advances the cartridge strip to the next
cartridge.
The tool is then ready to drive the next fastener.
8.6 Unloading the tool 5
Check that there is no cartridge strip or fastener in the
tool.
If there is a cartridge strip or fastener in the tool, pull the
cartridge strip up out of the tool by hand from above and
remove the fastener from 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.
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 damaged or when the
controls do not function faultlessly. If necessary, the tool
should be repaired by Hilti Service.
