7.2.4 Driving fasteners with the magazine
tool 5
1. Press the tool against the working surface at
right angles.
2. Drive the fastener by pulling the trigger.
3. Prepare the tool for driving the next fastener by
pushing the cycling grip back toward the rear of
the tool and then forward to its original position.
7.2.5 Checking and adjusting fastener driving
depth 3 6
NOTE
Fastener driving depth can be adjusted by turning
the power regulation wheel on the tool (setting 1 =
minimum; setting 4 = maximum).
1. Use the test gauge to check nail stand-off.
2. If a fastener is not driven deeply enough, driv-
ing power must be increased. Adjust the power
regulation wheel to the next higher setting. If a
fastener is driven too deeply, check to ensure that
a supporting member (e.g. a beam) is present at
this point. Do not drive fasteners into unsuppor-
ted sheet metal. Check to ensure that the metal
sheets lie snugly against the supporting struc-
ture or, respectively, that any gaps beneath the
sheets are kept to an absolute minimum.
3. Drive a fastener.
4. Use the test gauge to check nail stand-off.
5. If the fastener is still not driven deeply enough
or, respectively, is driven too deeply, steps 2
to 4 must be repeated until the correct depth
is achieved. If necessary, use a cartridge with a
higher or lower power rating.
7.3 Unloading the tool
7.3.1 Removing cartridges from the tool 7
WARNING
Do not attempt to forcibly remove cartridges from
the magazine strip or tool.
1. Advance the cartridge strip through the tool by
moving the cycling grip until the strip is visible
at the exit aperture.
2. Pull the cartridge strip out of the tool at the
cartridge strip exit aperture.

7.3.2 Removing fastener strips from the tool 8
WARNING
Check that no cartridge strip is loaded in the tool. If
a cartridge strip is still present in the tool, operate
the cycling grip until the strip projects from the tool
and then pull the strip out of the cartridge strip exit
by hand and remove it from the tool.
CAUTION
The fastener strip will be ejected by spring pressure.
1. Push the fastener strip 5 mm further into the
magazine and hold it securely in this position.
2. Push the catch forward with the thumb and hold
it in this position.
3. Remove the fastener strip from the magazine.
7.4 Changing the nail magazine or fastener
guide (accessory)
7.4.1 Disassembly 9
WARNING
All cartridges must be removed from the tool. All
nails must be removed from the nail magazine or
the fastener guide.
CAUTION
After the tool has been in use, the parts to be handled
may be very hot. It is essential that gloves are worn
if the following maintenance operations have to be
carried out before the tool has been allowed to cool
down.
1. Check that the tool cycling grip is in its starting
position.
2. Unscrew and remove the fastener guide (or
fastener magazine).
3. Remove the piston brake from the fastener guide.
7.4.2 Assembly 10
1. Insert the piston brake, the right way round, in
the piston guide (or fastener magazine) that is to
be fitted to the tool.
Exception: With the HVB base plate, the piston
stopper must be inserted the right way round
(rubber part toward the front).
