1 SAFETY PRECAUTIONS
SAFETY PRECAUTIONS
Prepare for Loading
1. Prior to using the tool, make sure it
is unloaded and then do the functional
check: Check the functioning of the tool,
without a powder load or fastener, by
pushing down against the work surface,
making sure the groove on the barrel
aligns with the markings on the receiver.
Repeat this several times to insure tool is
operating properly.
2. Always check the material being fastened into, by performing the Center
Punch Test: Using a fastener as a center punch, strike the fastener against the
work surface using an average hammer blow and check the results. Wear eye
protection while performing this test.
1. If the fastener point
is blunted, material
is too hard.
(Typical base materials: poured concrete, structural steel and masonry.)
2. If material cracks or
shatters, material is
too brittle.
3. If the fastener pen-
3. If the base material is suitable for powder
actuated fasteners, make a test fastening
into a suitable base material with a number 1 (gray) load. If the number 1 load
does not fully set the fastener, try the next
higher power load until the proper level
is found. Failure to properly test fire to
determine correct power level may result
in overpowering the fastener, causing
it to pass completely through the work
material, injuring someone on the other
side. Overpowering the fastener may also
damage the tool.
SAFETY PRECAUTIONS
etrates the material
easily, material is
too soft.
4. If the fastener makes
small indentation into
material, material is
suitable for fastening.
Power Levels Available for HD22:
Power Level No. Color
1. Gray Weakest
2. Brown
3. Green
4. Yellow Strongest
NOTE: Ramset loads are designed for
use with Ramset tools. Do not attempt
to use other power loads. Doing so may
lead to unintentional load discharge as
well as damage to the tool. This tool is
NOT designed to use red (5) or purple
(6) power level loads. Using red (5) or
purple (6) loads can result in serious
injury to the operator or bystanders.

SAFETY PRECAUTIONS
Operating the Tool
1. Always point the tool away from people
and in a safe direction.
2. Never use tool when explosives or flam-
mable materials are nearby.
3. Never fire the tool without a fastener.
The piston will protrude from the muzzle
of the tool, enter the work surface and
possibly cause injury to the operator or a
bystander. Firing without a fastener may
also damage the tool.
4. Always hold the tool perpendicular to the
work surface to avoid serious injury or
death from ricocheting fasteners. Use a
spall guard* whenever possible.
5. Never set a fastener too close to another
fastening or a free edge. This can cause
the fastener to ricochet. Always follow
the minimum spacing and edge distance
requirements.
6. Never fire into very hard or brittle mate-
rials such as cast iron, tile, glass or
rock. These materials can shatter, causing
sharp fragments and/or the fastener to fly
freely.
* To order optional spall guard,
call 1-877-ITW-BRANDS (1-877-489-2726)
3 SAFETY PRECAUTIONS
SAFETY PRECAUTIONS
7. Never fasten into structural steel base
material thinner than 3/16". Never fasten
into concrete base material thinner than 3
times shank penetration. Always maintain
minimum penetration requirements.
8. Fastening into block and masonry is not
recommended. When it is necessary to fasten into masonry walls, it is recommended
that fasteners be driven into the horizontal
joints only. Published holding values for
these materials is not available due to the
inconsistency of the materials.
9. Never fasten through or into a hole. Always
maintain at least 1/2" distance from any
pre-drilled or pre-punched hole.
10.
Should you decide not to make a fastening
after the tool has been loaded, always
remove the powder load first, then the
fastener. Never attempt to pry an unfired load
out of the tool. Call The Technical Department
at 1-877-ITW-BRANDS (1-877-489-2726) for
assistance.

Handling Tool and Powder Loads
1. Never leave a loaded tool unattended.
Someone may pick it up, not know it is
loaded and accidentally discharge the tool
causing serious injury or death. Never load
the tool until you are prepared to complete
the fastening. Always store loads and tool,
unloaded, under lock and key.
SAFETY PRECAUTIONS

SAFETY PRECAUTIONS
2. Never carry fasteners or other hard
objects in the same pocket or container
with powder loads. The loads could be set
off, causing serious injury or death.
3. A person that is color blind must be extra
careful when loading the tool. One must
only take a load from a box that is identified by powder load number. Never use
loose loads that can be misidentified.
4.
Powder loads must never be used in firearms. They are more powerful than the
charges normally used in small firearms.
This could result in serious injury or death.
Fasteners
1. A powder actuated fastener, after it has
been installed, is considered a permanent
fastening. Do not attempt to pull a fastener
out of concrete or steel. Attempting to do
so may result in serious injury.
Operating Problems
1.
If the tool fails to fire, hold the tool firmly against
the material for 30 seconds. Remove the tool
from the work surface, open the barrel to reset
the piston. Re-chamber the load and repeat
firing sequence. If the tool fails to fire again,
hold for 30 seconds, unload the tool, and then
discard the load into a bucket of water. Never
attempt to pry an unfired load out of the tool.
Call The Technical Department at
1-877-ITW-BRANDS (1-877-489-2726) for

CAUTION!
operate the tool. Check to be sure the tool is unloaded and no foreign objects or
fasteners are in the barrel. Perform daily function test before operating.
OPERATION
Check the functioning of the tool, without a powder load or fastener in the tool, by
pushing down against the work surface, checking to be sure the groove portion of
the barrel aligns with the arrows on the tool body. Function unloaded tool several
times and insure that the breech parts and firing mechanism operate freely before
fastening with the tool.
1. Point the tool in a safe direction and slide
the barrel forward with your other hand.
This action resets the piston for the next
fastening. Loss of power may be the result
of an improperly reset piston.
2. Place a fastener, point out, into the front
end of the barrel until the plastic fluted tip
fits inside. Always load the fastener before
inserting the power load to prevent accidental discharge. Do not use excessive
force when inserting the fastener. Stop if
excessive force is required and call 1-877
ITW-BRANDS for technical assistance.
and complete the Operator's Exam before attempting to
3. Insert the powder load after making sure
the chamber is clear. The powder load will
not fully set until the tool is compressed
against the work surface. Always start
with the lowest level and increase until the
proper level is found. Note: Overpowering
a fastener into steel or concrete is
dangerous.
Note: Before making the fastening, the base material should be center punch tested
for suitability of powder actuated fastenings (see pg. 2).
7 TOOL OPERATION
TOOL OPERATION
4. Close tool by pulling the barrel back to
the semi-closed position. Never attempt
to close the tool by exerting force on the
front of the barrel. Never place your fingers
or hands over the muzzle end of the barrel. The proper position of the hands and
fingers are shown in the illustration.
5. With the tool in the semi-closed position,
place it against the material to be fastened.
Hold the tool firmly at 90º with one hand and
completely depress, check to be sure the
groove on the barrel aligns with the marking
on the receiver.
6. Using a one pound hammer, strike the
firing pin button with a sharp, firm blow.
If the tool fails to fire, follow the misfire
procedure on page 5.
Note: It is important to strike the firing pin button
firmly and squarely. A light blow or one off-center
may not activate the load, however it will jar the
piston out of position which will cause a reduction in
power. (See Troubleshooting, page 10.)

7. To prepare for the next fastening, point the
tool in a safe direction, and slide the barrel
firmly forward. This action ejects the fired
load out of the tool and properly resets the
piston. The tool is now ready for the next
fastening.
THOROUGH CLEANING
To maintain your tool in good working condition, it is recommended that the tool be
cleaned after heavy use or constant exposure to dirt and debris. Call 1-877-ITW-BRANDS

TROUBLESHOOTING
Tool operator must carefully follow all operating instructions and
precautions to successfully operate the tool. Following is a list of
potential situations an operator may encounter and the probable causes:
• If a tool problem occurs and technical assistance is required, please
call 1-877-ITW-BRANDS (1-877-489-2726)
WARNING: Do not operate a tool that is not functioning properly.
TOOL FAILS TO FIRE
There are three causes for most all misfires.
• Firing pin button struck
too lightly
• Firing pin button
struck off center
• Tool not completely
compressed
INCONSISTENT FASTENER SETTING
The major reason for inconsistent fastening is the improper position of
the piston. There are two reasons for an improperly positioned piston:
1. Failure to completely reset the piston.
2. A missed hit of the rear button.
In both cases the barrel must be fully
extended to reset the piston.
Note: It is a good practice to fully extend the
barrel and re-chamber the load after the tool is
improperly struck causing a misfire, and after
the misfire procedure has been followed.
9 TROUBLESHOOTING
TROUBLESHOOTING
PISTON OVERDRIVE
Piston overdrive is a problem that occurs after
the tool is fired. The piston may extend into the
work surface as much as 1/2".
can occur because of several reasons:
• Powder load too strong
• Soft base material
• Void in the masonry
material that you're
fastening into.
• Incorrect fastener selection.
Piston overdrive
Caution: Constant overdrive will damage the tool beyond repair. For technical
assistance or service information call 1-877-ITW-BRANDS (1-877-489-2726).
Note: When overdrive occurs, the piston may jam
into the front barrel. In this case be sure the tool
is unloaded, turn the tool upside down and place
on the work surface. Strike the exposed piston
with a hammer until it moves downward into the
barrel. Reset the piston. Wear safety goggles when
performing this task.
TO AVOID PISTON OVERDRIVE
• Decrease power level.
Always make test fastenings
with lightest load and increase
until proper level is found.
• Make sure base material is
checked according to the
Center Punch Test.
• When fastening into masonry,
always make fastenings into
horizontal joints.
• Check page 12, "How to Select
a Power Actuated Fastener."
Note:
Fastening to Concrete
When fastening into concrete always maintain a minimum 3" spacing between
fastenings and 3" from any free edge. Penetration into concrete should always be 1"
(see page 12, "How to Select a Powder Actuated Fastener"). The concrete thickness
should be at least 3 times the penetration depth.
Fastening to Steel
When fastening into steel always maintain a minimum 1-1/2" spacing between fastenings and 1/2" from any free edge. Fastener length should be long enough to penetrate
the steel completely (see page 12) Steel thickness is limited to 3/16" to 5/16".
