There are two types of Powder Actuated Tools:
CAUTION: The PT-22 is capable of fastening into concrete and/or steel. The
fastener enters the work surface with an extreme amount of energy. Make certain
not to misdirect the energy.

2. POWER LOAD SELECTION
1. The PT-22 is designed to use 4 levels of powder loads, each identified by
a number and color as follows:
For PT-22 / .22 caliber “A” crimp loads
2. When making a test fastening start with the lightest load first going up one
level at a time until the proper level is attained.
3. WARNING - Do Not Overpower, doing so many cause the fastener to break
and ricochet or pass completely through material and escape.
4. Do not attempt to force a load into the chamber of a tool.
Failure to observe these or any other warnings in this manual may result in
serious injury or death.
Simpson Strong-Tie power loads are
color-coded for safety and identification
purposes. Power level should be noted
before selecting and/or using load.
In addition each box of power loads is
labeled with an indicator dial denoting
the energy level on a scale from 1
(lowest) to 12 (highest). Power loads
numbered 1 through 6 have a brass
case, and those numbered 7 through 12
have a nickel case finish.

DIRECT-ACTING TYPE TOOL
Direct-acting type tools work by expanding gases that act directly on the
fastener without the use of a piston. Direct-acting tools are no longer
manufactured in North America and are regarded as far less safe to operate
than indirect-acting tools.
INDIRECT-ACTING TYPE TOOL
Indirect-acting type tools work by expanding gases that act directly on a
piston which drives the piston forward to strike the fastener.
