3 Check the correct answer.
1 It is necessary to read the Operator's Manual
prior to operating a D WALT low velocity tool.
e
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.
True False
9 Which one of the following materials
is usually suitable for powder actuated
fastenings?
poured concrete
hollow tile
surface hardened steel
glazed brick
10 In concrete, a fastener should be driven no
closer to an unsupported edge than:
1/2"(13mm)
1-1/2"(38mm)
3"(76mm)
11 Fishhooking is a condition which
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.
True False

15 After conducting a Center Punch Test,
the best way to check the base material
is to set several fasteners using the least
powerful load.
True False
16 Eye protection and hearing protection
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.
True False
18 List the proper powder load level number
(1-6) next to each
color listed.
Red ___ Brown ___
Green ___ Yellow ___
Gray ___ Purple ___
19 The weakest power level should
be used when making the first fastening.
True False
20 You can fasten into welded areas of steel.
True False

• The proper procedure if a powder load fails
to ignite is to hold the tool against the work
surface and wait 30 seconds, then proceed
exactly as directed in the Operator's Manual.
True False
• DEWALT Fasteners powder loads for the
P35s are .22 caliber, "A" tapered, neck down,
rim fire, short crimped cartridges. No other
powder load may be used in this tool.
True False
• Operators should never compress the P35s
or any other powder actuated tool against any
part of their body.
True False
• If a piston buffer for the P35s becomes
deformed, simply remove it, and use the tool
without the buffer?
True False
