Safety Precautions
KNOW YOUR FASTENING BASE
MATERIAL
1. ALWAYS know the thickness and
type of base material into which you
are fastening. NEVER GUESS.
Test the base material by using the
Center Punch Test. The Center
Punch Test is performed by using a
hammer to test drive the particular
fastener to be used into the material. If the point penetrates easily,
the material is too soft. If the point
becomes blunt, the material is too
hard. If the material fractures,
cracks or shatters, the material is
too brittle. Test fastenings should
always be made starting with the
lowest power load (Gray-Level 1)
and proceeding with the order
shown. Operators and bystanders
must ALWAYS wear goggles and
ear protection that meet or exceed
CE standards.
2. NEVER attempt to drive fasteners
into very hard or brittle materials
including, but not limited to cast
iron, glass, tile, stone, brick, or hardened steel. Materials of this type
tend to shatter and create hazard
from flying particles.
3. NEVER make fastenings in spalled
or cracked areas.

Safety Precautions
4. NEVER drive fasteners into thin or
easily penetrated materials unless
it is backed by concrete or steel.
When in doubt, such as when base
material is concealed, conduct a
Center Punch Test. Check continually to avoid fastening into unsuitable material, especially in older
buildings.
5. DO NOT fasten thru or within 13mm
(1/2”) of predrilled or pre-punched
holes.
6. DO NOT drive fasteners into concrete less than three times as thick
as the intended fastener penetration, within 76mm (3”) of the edge,
within 76mm (3”) of another fastener or within 76mm (3”) of a failed
fastener.
7. DO NOT drive fasteners into steel
base material less then 5mm
(3/16”) thick, within 51mm (2”) of a
weld, within 13mm (1/2”) of the
edge or within 25mm (1”) of another
fastener.
8. When fastening into masonry walls,
always drive into horizontal mortar
joints, NEVER into vertical mortar
joints. BE CAREFUL, a poorly laid
joint may permit too much penetration, and/or unsatisfactory holding
power.

2. Remington Powder Loads are
available in four power levels with
gray (1) being the lowest power
level and yellow (4) being the highest power level. Always start with
the lowest power level (gray-level 1)
and increase until a proper fastening is made.Always use Remington
powder loads or loads manufac-
tured to specifications outlined in
the P.A.T.M.I. “Technical Data Pertaining to Powder Loads (Boosters)”.
3. NEVER use powder loads in firearms.
4. NEVER carry fasteners or other
hard objects in the same pocket or
container with powder loads.
5.A color blind person must take extra
precautions to prevent the chance
of mixing the powder loads of various levels.
6. Fasteners are a permanently installed fixture. An act of demolition
is required for their removal. Appropriate safety precautions must be
taken.

Safety Precautions
7. NEVER use fasteners longer than
63.5mm (2 1/2”). NEVER use common nails. Remington Power Fasteners are manufactured from special steel and heat treated to produce a very hard, yet ductile fastener.
8. NEVER pry a load out of the chamber. Prying can discharge the load
causing serious injury.
9. ALWAYS insert the fastener first,
then the powder load. If work is
interrupted for any reason, AL-
WAYS remove the powder load
before removing the fastener.
Why A Fastener Holds
CONCRETE:
As a general rule, penetration should be
approximately 25mm to 32mm (1” to 1 1/
4”) into the base concrete. Make sure
the concrete is at least three times as
thick as the intended fastener penetration. Never have the fastener point
protude thru the concrete.
NOTE: Concrete needs to cure for 28
days before maximum fastening holding
power will be achieved.
STEEL:
In steel, the point of the fastener must
penetrate completely through for highest holding power. If not, the spring
action of the steel pushes back on the
point and tends to force the fastener out.
Recommended application are between
5mm to 8mm (3/16-5/16”) steel.

Overdriven Fasteners
An overdriven fastener results when too
strong of a powder load is used causing
the piston to extend past the muzzle.
Move to the next lightest powder load.
Repeated overdrive will damage your
tool. By avoiding overdrive, you can extend the life of your tool considerably.
NOTE: NEVER fire the tool without a
fastener. This can damage the tool and/
or cause possible injury to the operator.
IMPORTANT: If the tool does not open
after firing and the piston is overdriven,
see
Piston Overdrive
, page 18.

LOADING THE POWERHAMMER
1. Insert the proper fastener into the
muzzle, round metal head first.
Push fastener until the point is even
with the end of the muzzle.
2. Grab the muzzle and pull forward
until it stops. This sets the piston
and opens the chamber area.
3. Insert the proper Remington Powder Load into the chamber, while
holding the muzzle downward. Be
sure to keep holding the muzzle
downward and away from you. The
powder load will not seat fully.
4. Push the barrel into the housing
until it stops and hold in the closed
position keeping the muzzle
pointed down. This keeps the powder load from falling out of the chamber.
FIRING THE POWERHAMMER
1. Place the muzzle of the tool against
the work surface, hold at 90°, Do
Not Tilt.
2. Hold the grip with one hand and
push down, compressing the
spring. The groove around the barrel and outside of the housing at the
chamber area MUST line up (as
shown) for the tool to operate properly. If the grooves DO NOT line up,
check that the powder load has not
fallen out of the chamber.
3. ALWAYS keep the chamber opening away from the wrist to avoid
contact from escaping gas.
4. Using a one pound hammer, HIT
THE FIRING PIN SQUARELY
WITH A SHARP, STRONG BLOW.
Hold the hammer as close as you
can to the tool head to improve your
accuracy. For best results, work at a
level below shoulder height.
5. If the powder load does not fire with
the first blow, wait 30 seconds, eject
the powder load and start over
again. NOTE: A LIGHT HAMMER
BLOW WILL JAR THE DRIVE PISTON OUT OF PROPER POSITION
CAUSING LESS POWER AND
PENETRATION OF THE FASTENER.

6. After the fastening is made, remove
the tool from the work surface. Grab
the barrel and pull forward rapidly.
This ejects the spent load and sets
the piston in the firing position.
7. NOTE: THE TOOL CANNOT BE
FIRED IN THE OVERHEAD POSITION.
PISTON OVERDRIVE
If the tool does not open after firing and
the piston is 13mm (1/2 ”), or more out of
the muzzle:
1. Place the muzzle end of the tool
against wooden work surface and
hold grip with one hand.
2. Hit the firing pin with a hard hammer
blow several times and force piston
back into muzzle.
3. Eject the powder load. (See step 6
of
Firing The Powerhammer
OVERDRIVE
).
CARE OF YOUR POWERHAMMER
Clean your Powerhammer after each
day’s use. Clean chamber with accessory wire brush, part number 56485.
Apply good quality penetrating lubricant
spray (such as WD-40) sparingly and
wipe dry.
NOTE: The labor regulations of many
counties require that the operator of this
tool on a job site be thoroughly trained
and certified for compentence prior to
operating this tool.
