Safety Precautions
BEFORE USING
1. ALWAYS handle the tool as if it
were loaded. Before starting work,
check that the tool is unloaded and
the muzzle is clear. NEVER load a
tool unless it is going to be used.
2. ALWAYS inspect to make sure the
tool is working properly. If the tool
does not work properly or is dam-
aged remove from service and tag
DEFECTIVE.
3. Operators and bystanders must
ALWAYS wear goggles and hear-
ingprotectionwhichmeetorexceed
the accepted standards for ad-
equateprotectioninyourcountry.In
the U.K., refer to BSI standards.
4. ALWAYS clearthe workareaon all
sides and post appropriate warning
signs on job sites.
The following pages contain detailed
warnings, cautions, and rules of safe
operation. Read carefully and become

or cracked areas.
Safety Precautions
KNOW YOUR FASTENING BASE
MATERIAL
1. ALWAYS know the thickness and
typeofbasematerialintowhichyou
are fastening. NEVER GUESS.
Test the base material by using the
Center Punch Test. The Center
PunchTestis performed by using a
hammer to test drive the particular
fastener to be used into the mate-
rial. 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. ALWAYS wear approved
goggles.
2. NEVER attempt to drive fasteners
into very hard or brittle materials
including, but not limited to cast
iron,glass,tile,stone,brick,orhard-
ened steel. Materials of this type
tend to shatter and create hazard
from flying particles.

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
CenterPunchTest.Checkcontinu-
ally to avoid fastening into unsuit-
able material, especially in older
buildings.
5. DO NOT fasten thru or within
12.7mm (1/2") of predrilled or pre-
punched holes.
6. DO NOT drive fasteners into con-
crete less than three times as thick
as the intended fastener penetra-
tion, within 76mm (3") of the edge,
within 76mm (3") of another fas-
tenerorwithin76mm(3") ofafailed
fastener.
7. DO NOT drive fasteners into steel
base material less then 4.8mm
(3/16") thick, within 51mm (2") of a
weld, within 12.7mm (1/2") of the
edgeorwithin25mm(1")ofanother
fastener.
8. Whenfasteningintomasonrywalls,
always drive into horizontal mortar
joints, NEVER into vertical mortar
joints. BE CAREFUL, a poorly laid
joint may permit too much penetra-
tion, and/or unsatisfactory holding
power.

face for 30 seconds. Then remove
the tool, eject the load and safely
discard the misfired load into water
or oil. Return misfired power loads
to SGB Youngman or an approved
distributor.
3. ALWAYSusethespallshieldwhen

Always start with the lowest power
level (gray-level 1) and increase until
a proper fastening is made.
CAUTION: Always use Remington

Safety Precautions
Why A Fastener Holds
7. NEVER use fasteners longer than
68mm(211/16").NEVERusecom-
mon nails. Remington Power Fas-
teners are manufactured from spe-
cial steel and heat treated to pro-
duce a very hard, yet ductile fas-
tener. Remington tools drive flat-
headed fasteners. The use of
dome-headed fasteners can dam-
age your tool.
8. NEVER pry a load out of the cham-
ber. Prying can discharge the load
causing serious injury.
9. ALWAYS insert the fastener first,
thenthe power load.If work is inter-
rupted for any reason, ALWAYS
remove the power load before re-
moving the fastener.
CONCRETE:
Asa general rule, penetration should be
approximately 22mm (7/8") to 32mm
(1 1/4") into the base concrete. Make
sure the concrete is at least three times
as thick as the intended fastener pen-
etration. Never have the fastener point
protude thru the concrete.
NOTE: Concrete needs to cure for 28
daysbeforemaximumfastening holding
power will be achieved.
STEEL:
In steel, the point of the fastener must
penetrate completely through for high-
est holding power. If not, the spring
action of the steel pushes back on the
pointandtendstoforcethe fastenerout.
Recommendedapplicationarebetween
4.8mm (3/16")-8mm (5/16") steel.

15
Safety Precautions
Overdriven Fasteners
An overdriven fastener results when too
strong of a power load is used causing
the piston to extend past the muzzle.
Move to the next lightest power load.
Repeated overdrive will damage your
tool. By avoiding overdrive, you can ex-
tend 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
fasteneruntilthepointisevenwiththe
end of the muzzle.
2. Grabthemuzzleandpullforwarduntil
it stops. This sets the piston and
opens the chamber area.
3. Insert the proper Remington Power
Loadinto the chamber, whileholding
the muzzle downward. Be sure to
keep holding the muzzle downward
and away from you. The power load
will not seat fully.
4. Push the barrel into the housing until
itstopsandholdintheclosedposition
keeping the muzzle pointed down.
Thiskeepsthepowerloadfromfalling
out of the chamber.
FIRING THE POWERHAMMER
1. Place the muzzle of the tool against
theworksurface,hold at90°,DoNot
Tilt.
2. Holdthegripwithonehandandpush
down, compressing the spring. The
groovearoundthebarrelandoutside
of the housing at the chamber area
MUST line up (as shown) for the tool
tooperateproperly.IfthegroovesDO
NOT line up, check that the power
loadhasnotfallenoutofthechamber.
3. ALWAYSkeepthechamberopening
away from the wrist to avoid contact
from escaping gas.
4. Usingaonepoundhammer,HITTHE
FIRING PIN SQUARELY WITH A
SHARP, STRONG BLOW. Hold the
hammer as close as you can to the
tool head to improve your accuracy.
Forbestresults,workatalevelbelow
shoulder height.
5. Ifthepowerloaddoesnotfirewiththe
first blow, wait 30 seconds, eject the
power load and start over again. Re-
turn misfired power loads to SGB

NOTE: The labor regulations of many
communitiesrequire thatthe operatorof
this tool on a job site be thoroughly
trained and certified for compentence
prior to operating this tool. Contact SGB
Youngman or the nearest distributor for
trainings.
6. Afterthefasteningismade,remove
thetoolfromtheworksurface.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 POSI-
TION.
PISTON OVERDRIVE
If the tool does not open after firing
andthepistonis12.7mm(1/2"),ormore
out of the muzzle:
1. Place the muzzle end of the tool
against wooden work surface and
hold grip with one hand.
2. Hitthefiringpinwithahardhammer
