WARNING
Never make the tool ready to fire by pressing it against a
part of the body (e.g. the hand). This could cause a nail
or the piston to be driven into a part of the body. Never
press the tool against a part of the body.
WARNING
Never redrive a fastener. This may cause the fastener
to break and the tool may jam.
WARNING
Never drive fasteners into existing holes unless this
is recommended by Hilti (e.g. DX‑Kwik).
CAUTION
Do not exceed the recommended fastener driving rate
(number of fasteners driven per hour).
8.1 Procedure if a cartridge fails to fire
If a cartridge fails to fire or misfires, always proceed as
follows:
Keep the nose of the tool pressed at right angles against
the working surface for 30 seconds.
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 3
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.
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-
8.3 Setting the power level 4
1.
Select a cartridge power level and power setting to
suit the application.
2.
If you cannot estimate this on the basis of previous
experience, always begin with the lowest power.
Select a cartridge of the lowest power level (color
code) and turn the power regulating wheel to 1.
3.
Drive a nail.
If the nail doesn't penetrate deeply enough, increase
the driving power by turning the power regulating
wheel. If necessary, use a more powerful cartridge.
8.4 Driving a fastener 5
DANGER
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 Cycling the tool 6
NOTE
If the cycling action is stiff (i.e. pulling out, pushing back
in), 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 move the nose unit 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 7
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.
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.
