der actuated tool and loads in a
locked container. Keep powder
loads of different power levels in
separate containers.
3. NEVERcarryorpassaloadedpow-
der actuated tool. NEVER point a
powder actuated tool at anyone.

Safety Precautions
KNOW YOUR FASTENING BASE
MATERIAL
1. ALWAYS know the thickness and
typeofbasematerialintowhichyou
are fastening. NEVER GUESS.
Test the base material by using the
Center Punch Test. The Center
Punch Test is performed by using a
hammer to test drive the particular
fastener to be used into the mate-
rial. If the point penetrates easily,
the material is too soft. If the point
becomes blunt, the material is too
hard. If the material fractures,
cracks or shatters, the material is
too brittle. Test fastenings should
always be made starting with the
lowest power load (Gray-Level 1)
and proceeding with the order
shown. Operators and bystanders
must ALWAYS wear goggles and
ear protection that meet or exceed
CE standards.
2. NEVER attempt to drive fasteners
into very hard or brittle materials
including, but not limited to cast
iron,glass,tile,stone,brick,orhard-
ened steel. Materials of this type
tend to shatter and create hazard
from flying particles.

Safety Precautions
4. NEVER drive fasteners into thin or
easily penetrated materials unless
it is backed by concrete or steel.
When in doubt, such as when base
material is concealed, conduct a
Center Punch Test. Check continu-
ally to avoid fastening into unsuit-
able material, especially in older
buildings.
5. DONOTfastenthruorwithin13mm
(1/2”) of predrilled or pre-punched
holes.
6. DO NOT drive fasteners into con-
crete less than three times as thick
as the intended fastener penetra-
tion, within 76mm (3”) of the edge,
within 76mm (3”) of another fas-
tener or within 76mm (3”) of a failed
fastener.
7. DO NOT drive fasteners into steel
base material less then 5mm
(3/16”) thick, within 51mm (2”) of a
weld, within 13mm (1/2”) of the
edgeorwithin25mm(1”)ofanother
fastener.
8. Whenfasteningintomasonrywalls,
always drive into horizontal mortar
joints, NEVER into vertical mortar
joints. BE CAREFUL, a poorly laid
joint may permit too much penetra-
tion, and/or unsatisfactory holding
power.
