3 Check the correct answer.
1 It is necessary to read the Operator's Manual
prior to operating a DEWALT low velocity
tool.
True False
2 When fastening into concrete, the base
material should be greater than the shank
penetration by at least:
1 time
2 times
3 times
3 When operating a powder actuated tool, your
hand should never be placed:
around the tool body
in front of the tool muzzle
over the tool handle
4 To determine the suitability of a base
material, use the fastener as a center punch.
• If the fastener is blunted, do not fasten; the
material is too:
soft hard brittle
• If the fastener penetrates easily, do not
fasten; the material is too:
soft hard brittle
• If the material cracks or shatters, do not
fasten; the material is too:
soft hard brittle
5 Unsafe applications for powder actuated
tools may be caused by which of the
following?
a soft base material
improper powder load
fastening too close to
an unsupported edge
a malfunctioning tool
fastening into a spalled area
fastening through a
pre-existing hole
all of the above
6 Which one of the following building materials
is not suitable as a receiving material (base
material) for powder actuated fasteners?

7 When considering the safety of a particular
application, the operator must think about:
the base material
the powder load power level
the operator's safety
the safety of bystanders
and fellow workers
all of the above
8 The proper loading procedure is: insert fastener
first, powder load second. The fastener should
always be placed in the tool prior to the load.

1/2"(13mm)
1-1/2"(38mm)
3"(76mm)

can occur when a powder actuated
fastener strikes a piece of hard aggregate
or very hard concrete, bends and comes out
of the work surface. A fishhook can cause a
serious injury or death.
True False
12 Placing a hand over the muzzle bushing of a
loaded tool can result in serious injury from
piston overdrive or an escaping fastener if
the tool is discharged accidentally.
True False
13 Piston overdrive is caused by overpowering
of the tool or by discharging the tool against
a soft surface.
True False
14 Malfunctioning tools cannot be used and
must be removed from service immediately.

15 After conducting a Center Punch Test,
the best way to check the base material
is to set several fasteners using the least

should not be worn by the operator and any
necessary bystanders when using the tool.
True False
17 A powder actuated tool cannot be safely
used in an explosive or flammable
atmosphere.
