POWER ADJUSTMENT

The power adjustment mechanism of the PA3500 allows the user to adjust the
penetration of the pin through the fixture ensuring a precise fastening. To operate the
power adjustment mechanism, move the scroll wheel which is situated on the PA3500
housing in the + or – direction to increase or decrease the power of the tool thus
adjusting the pin penetration.
1 = minimum power
3 = medium power
6 = maximum power
Note: Start with minimum power. If the fastener does not penetrate deep enough,
increase the power.
FASTENER FUNCTIONING
Prior to learning the safe operating procedures for this tool, it is important to understand
how a powder actuated fastener works. A powder actuated fastener is considered to be
a direct drive or forced entry type of fastener because it is driven directly into the base
material. The driving action causes tremendous forces to be applied to the fastener.
DEWALT powder actuated fasteners are specially designed and manufactured to
withstand the forces imposed during the driving operation. Only fasteners manufactured
or supplied by DEWALT should be used in this tool.
FUNCTIONING IN CONCRETE
The performance of a powder actuated fastener when installed into concrete or
masonry base materials is based on the following factors:
1. Strength of the base material
2. Hardness and concentration of the aggregate
3. Shank diameter of the fastener
4. Depth of embedment into the base material
Washer
5. Fastener spacing and edge distance
In addition to these factors, installation tool accessories such as a stop spall, which
reduces the tendency of the concrete surface to spall during the driving action, can
increase the performance of the fastener.
When a powder actuated fastener is driven into concrete, it displaces the volume of

concrete around the embedded area of the fastener shank. As this occurs, the concrete
directly surrounding the fastener is compressed and in turn presses back against the
shank of the fastener. Additionally, the driving action generates heat which causes
particles within the concrete to fuse to the shank of the fastener. This combination
of compression and fusion holds the fastener in the concrete base material. A similar
action occurs when fastening into block masonry.
Generally, the performance of the fastener in a given concrete strength will increase
with greater embedment depths in a certain range. Depending on the fastener style
