7.2.1 Loading MXR fastener strips
1. Insert 4 fastener strips in the magazine from above.
2. Press the last fastener strip into the magazine as far
as it will go.
7.2.2 Selecting the cartridge
1. Determine the thickness of the material to be fastened
and the strength of the supporting steel.
2. Select a suitable type of cartridge and power setting
for normal steel or high-strength steel (according to
cartridge recommendations).
7.2.3 Loading a strip of Hilti 6.8/18 M40
(=.27 CAL long) cartridges
1. Slide the cartridge strip into the cartridge loading chan-
nel from above.
2. Press the cartridge strip into the cartridge loading
channel until flush with the top edge of the channel.
7.2.4 Driving fasteners
-CAUTION-
Never attempt to redrive a fastener that has already been
driven. Use the tool only in an upright position with the
tool nosepiece (fastener exit aperture) pointing down-
wards.
-WARNING-
Never point the tool toward other persons.
1. Press the tool against the work surface at right angles.
2. Drive the fastener by pressing the trigger on the hand
grip.
7.2.5 Checking and adjusting fastener stand-off
Fastener stand-off (an indication of depth of penetra-
tion) can be adjusted by turning the power regulation
wheel on the tool (6).
Setting 1
= minimum
Setting 4
= maximum
1. Check the fastener stand-off. (5A)
2. If a fastener is not driven deeply enough, driving power
must be increased. Adjust the power regulation wheel
to the next higher setting. (5D) If a fastener is driven
too deeply, driving power must be decreased. (5E)
Adjust the power regulation wheel to the next lower
setting.
3. Drive a fastener.
4. Check the stand-off. (5A)
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 nec-
essary, use a cartridge with a higher or lower power
rating.
7.1 Using the tool
-NOTE-
Fastening instructions
These instructions must be observed at all times.
For detailed information, please ask your local Hilti rep-
resentative for a copy of the applicable technical guide-
lines or national technical regulations.
7. Operation
-WARNING-
●
Driving the fastener may cause
flying fragments (i.e. fragments of
the material fastened, the fastener
or cartridge strip etc.).
●
Flying fragments may injure parts
of the body or the eyes.
●
The operator and bystanders must
wear protective glasses and a hard
hat.
-WARNING-
●
Making the tool ready to fire
by pressing it against a part of
the body (e.g. the foot) is not
permissible.
●
This could cause a fastener to be
driven into a part of the body.
●
Never press the tool against a part
of the body.
-CAUTION-
●
The fastener is driven by the energy
released when a cartridge is fired.
●
An excessively high noise level may
damage the hearing.
●
The operator and bystanders must
wear ear protectors.
