Safety Notes
General Safety Rules for Pneumatic Tools
Read and observe all safety warnings and
instructions. Failure to follow the following
safety warnings and instructions may result in electric
shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
1) Work area safety
a)Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
b)Do not operate the pneumatic tool in explosive at-
mospheres, such as in the presence of flammable
liquids, gases or dusts. While working the work-
piece, sparks can be created which may ignite the
dust or fumes.
c)Keep children and bystanders away from your
workplace while operating the pneumatic tool. Dis-
tractions from other persons can cause you to lose
control over the pneumatic tool.
2) Pneumatic tool safety
a)Use compressed air of Quality Class 5 in accord-
ance with DIN ISO 8573-1 and a separate mainte-
nance unit close to the pneumatic tool. The com-
pressed air supplied should be free of foreign
material and moisture to protect the pneumatic tool
from damage, contamination, and the formation of
rust.
b)Check the connections and the air supply lines. All
maintenance units, couplers, and hoses should con-
form to the product specifications in terms of pres-
sure and air volume. Too low pressure impairs the
function of the pneumatic tool; too high pressure
can result in material damage and personal injury.
c)Protect the hoses from kinks, restrictions, sol-
vents, and sharp edges. Keep the hoses away from
heat, oil, and rotating parts. Immediately replace a
damaged hose. A defective air supply line may result
in a wild compressed-air hose and can cause per-
sonal injury. Raised dust or chips may cause serious
eye injury.
d)Make sure that hose clamps are always tightened
firmly. Loose or damaged hose clamps may result in
uncontrolled air escape.
3) Personal safety
a)Stay alert, watch what you are doing, and use com-
mon sense when operating a pneumatic tool. Do
not use a pneumatic tool while tired or under the
influence of drugs, alcohol, or medication. A mo-
ment of inattention while operating a pneumatic
tool may result in personal injury.
b)Use personal protective equipment. Always wear
eye protection. Protective equipment such as dust
mask, non-skid safety shoes, hard hat, or hearing
protection used for appropriate conditions will re-
duce personal injuries.
c)Prevent unintentional starting. Make sure that the
pneumatic tool is switched off before connecting
it to the air supply, picking it up or carrying it.
When your finger is on the On/Off switch while car-
rying the pneumatic tool or when connecting the
pneumatic tool to the air supply while it is switched
on, accidents can occur.
d)Remove any adjustment tools before switching on
the pneumatic tool. A wrench or key left attached to
a rotating part of a pneumatic tool may result in per-
sonal injury.
e)Do not overreach. Keep proper footing and bal-
ance at all times. This enables better control of the
pneumatic tool in unexpected situations.
f) Dress properly. Do not wear loose clothing or jew-
ellery. Keep your hair, clothing and gloves away
from moving parts. Loose clothes, jewellery or long
hair can be caught in moving parts.
g)If devices are provided for the connection of dust
extraction and collection facilities, ensure these
are connected and properly used. Use of dust col-
lection can reduce dust-related hazards.
h)Do not directly inhale the exhaust air. Avoid ex-
posing the eyes to exhaust air. The pneumatic
tool's exhaust air can contain water, oil, metal parti-
cles and debris from the compressor. This can cause
damage to one's health.
4) Pneumatic tool use and care
a)Use the clamping devices or a vice to secure and
support the workpiece. Holding the workpiece by
hand or against your body will not allow for safe op-
eration of the pneumatic tool.
b)Do not overload the pneumatic tool. Use the pneu-
matic tool intended for your work. The correct
pneumatic tool will do the job better and safer at
the rate for which it is designed.

c)Do not use a pneumatic tool that has a defective
On/Off switch. A pneumatic tool that cannot be
controlled with the switch is dangerous and must be
repaired.
d)Disconnect the air supply before making any ad-
justments, changing accessories, or placing the
pneumatic tool aside. This safety measure prevents
accidental starting of the pneumatic tool.
e)Store idle pneumatic tools out of the reach of chil-
dren. Do not allow persons unfamiliar with the
pneumatic tool or these instructions to operate
the device. Pneumatic tools are dangerous in the
hands of untrained users.
f) Maintain the pneumatic tool with care. Check for
misalignment or binding of moving parts, breakage
of parts and any other condition that may affect
the pneumatic tool's operation. Have damaged
parts repaired before using the pneumatic tool.
Many accidents are caused by poorly maintained
pneumatic tools.
g)Use the pneumatic tool, accessories, application
tools, etc. according to these instructions. Take in-
to consideration the working conditions and the
activities to be carried out. Use of the pneumatic
tool for operations different from those intended
could result in hazardous situations.
5) Service
a)Have your pneumatic tool repaired only through a
qualified repair person and only using original re-
placement parts. This will ensure that the safety of
the pneumatic tool is maintained.
Safety Warnings for Compressed-air
Nailers/Staplers
Wear safety goggles.
f Always assume that the pneumatic tool is loaded
with fasteners. Careless handling of the pneumatic
tool can lead to unexpected shot actuation of fasten-
ers and cause injury.
f When working, hold the pneumatic tool in such a
manner that your head and body cannot be injured in
case of sudden kickback due to a malfunction of the
energy supply or from hard objects/locations in the
workpiece.
f Never point the pneumatic tool at yourself or at per-
sons close by. Unexpected actuation will expel a fas-
tener, which can lead to injury.
f Do not actuate the pneumatic tool until firmly placed
against the workpiece. When the pneumatic tool is not
in contact with the workpiece, the fastener can bounce
away from the fastening point and overload the pneu-
matic tool.
Do not work on ladders or scaffolds when
the actuation system “Contact actuation” is
set. In particular, do not move from one fas-
tening location to another, close boxes or
enclosures, or fasten transport-securing fix-
tures on e.g., vehicles and waggons, via scaf-
folds, stairs, ladders or ladder-like construc-
tions, such as roof battens. With this
actuation system, a fastener will be dis-
charged each time when accidentally apply-
ing the pneumatic tool while the discharge
lock-off is pressed in. This can lead to injury.
f Observe the conditions of the job site. It is possible
that fasteners can burst through thin workpieces or be
deflected when working in corners or against edges,
and harm persons.
Disconnect the air supply, when the fasten-
er is jammed in the pneumatic tool. When
the pneumatic tool is still connected to the
power supply, it can accidentally be actuated
when removing a jammed fastener.
f Use caution when removing a jammed or stuck fas-
tener. The system can be under tension and cause the
fastener to be shot or thrust out, while attempting to
clear the jam.
f Do not use this to pneumatic tool to fasten electrical
wiring. It is not suitable for fastening electrical wiring,
can damage the insulation of electric cables and thus
lead to electric shock and danger of fire.
f Never use oxygen or flammable gases as the energy
source for the pneumatic tool. Flammable gases are
dangerous and can cause the pneumatic tool to ex-
plode.
f Use appropriate detectors to determine if utility lines
are hidden in the work area or call the local utility
company for assistance. Contact with electric lines
can lead to fire and electric shock. Damaging a gas line
can lead to explosion. Penetrating a water line causes
property damage or may cause an electric shock.

f The pneumatic tool may only be connected to lines,
for which the maximal permissible pressure of the
pneumatic tool cannot be exceeded by more than
10 %; for higher pressures, a pressure control valve
(pressure reducer) with preceding pressure-limita-
tion valve in the compressed-air line must be in-
stalled. Excessive pressure leads to abnormal opera-
tion or breakage of the pneumatic tool, which can lead
to injury.

Assembly
Connecting the Air Supply (see figure A)
Make sure that the pressure of the compressed-air sys-
tem is below the maximum permitted rated pressure of
the pneumatic tool. Firstly, set the air pressure to the
lower value of the recommended rated pressure (see
“Technical Data”).
When in doubt, check the pressure at the air inlet with a
pressure gauge with the pneumatic tool switched on.
For maximum performance, the values for the supply-air
hose 17 (connection thread, maximum operating pres-
sure, inner hose diameter, maximum hose length; see
“Technical Data”) must be observed.
The compressed air supplied should be free of foreign
material and moisture to protect the tool from damage,
contamination, and the formation of rust.
All fittings, connecting lines and hoses must be dimen-
sioned for the pressure and the required air volume.
Avoid restrictions in the air supply, e.g., from pinching,
kinking, or stretching!
Connecting the Air Supply to the Pneumatic Tool
– Empty the magazine 8.
(See “Emptying the Magazine”, page 27)
For the following worksteps, a fastener can be dis-
charged when interior parts of the pneumatic tool are
not in the starting position due to repairs, maintenance
or transport.
– Connect the air connector 6 with a supply-air hose 17
equipped with an air-connection coupling 16.
– Check the proper function by placing the outlet 13 or
the rubber workpiece protector 1 of the pneumatic
tool onto a piece of scrap wood or wood material, and
discharging once or twice.
Loading the Magazine
Disconnect the air supply before making any
adjustments, changing accessories, or plac-
ing the pneumatic tool aside. This safety
measure prevents accidental starting of the
pneumatic tool.
f Use only original Bosch accessories (see “Technical
Data”). The precision parts of the pneumatic tool such
as the magazine, the outlet and the shot duct are
matched to Bosch staples, nails and brads. Other man-
ufacturers use other steel qualities and sizes.
Using fasteners not permitted, can damage the pneu-
matic tool and cause injuries.
While loading the magazine, hold the pneumatic tool in
such a manner that the outlet 13 is not pointed at your
own body or at other persons.

Operation
Actuation systems
The pneumatic tool can be operated with two different
actuations systems:
– Single actuation with safety run
With this actuation system, the discharge lock-off 2
must first be firmly pressed against the workpiece. A
fastener is not discharged until the trigger 10 is pulled.
Afterwards, further discharging procedures can only
be actuated, when the trigger and the discharge lock-
off have first been set back to the starting position.
– Contact actuation
With this actuation system, the trigger 10 must be
pulled first. A fastener is always discharged when the
discharge lock-off 2 is firmly pressed against the work-
piece while the trigger is pressed.
This enables a higher working speed to be achieved.
The actuation system is set via the selector switch 9.
Starting Operation
Disconnect the air supply before making any
adjustments, changing accessories, or plac-
ing the pneumatic tool aside. This safety
measure prevents accidental starting of the
pneumatic tool.
Working with Single Actuation (see figure D)

pivot it to the bottom position until it engages.
The actuation system “single actua-
tion” is set.
– Release the selector switch 9 again.
– Firmly position the outlet 13 or the rubber workpiece
protector 1 on the workpiece until discharge lock-off 2
is pressed in completely.
– Afterwards, briefly press trigger 10 and release again.
A staple (GTK 40) or a brad (GSK 50) is discharged.
– Allow the pneumatic tool to bounce back from the
workpiece.
– For another driving procedure, completely lift the
pneumatic tool from the workpiece and position it
firmly at the next desired location.
Working with Contact Actuation (see figure E)
– Press selector switch 9 inward and at the same time
pivot it to the upper position until it engages.
The actuation system “contact ac-
tuation” is set.
– Release the selector switch 9 again.
– Press and hold the trigger 10.
– Firmly position the outlet 13 or the rubber workpiece
protector 1 on the workpiece until discharge lock-off 2
is pressed in completely.
A staple (GTK 40) or a brad (GSK 50) is discharged.
– Allow the pneumatic tool to bounce back from the
workpiece.
– For another driving procedure, completely lift the
pneumatic tool from the workpiece and position it
firmly at the next desired location.
– Move the pneumatic tool uniformly over the workpiece
by lifting it off and applying it again.
Each time when applying the pneumatic tool while the
discharge lock-off is pressed in, a staple (GTK 40) or a
brad (GSK 50) is discharged.
– As soon as the desired amount of staples (GTK 40) or
brads (GSK 50) have been driven in, release trigger 10
again.
Working Advice
Disconnect the air supply before making any
adjustments, changing accessories, or plac-
ing the pneumatic tool aside. This safety
measure prevents accidental starting of the
pneumatic tool.
Check the proper function of the safety and actuation de-
vices, and the tight seating of all screws and nuts each
time before using.
Disconnect a defective or not properly operating pneu-
matic tool immediately from of the air supply and contact
an authorised service agent for Bosch power tools.
Do not perform any incorrect manipulations on the pneu-
matic tool. Do not disassemble or block any components
of the pneumatic tool, such as the discharge lock-off.
Do not carry out “emergency repairs” with unsuitable
means. The pneumatic tool is to be maintained regularly
and properly (see “Maintenance and Cleaning”, page 28).

Bosch Power Tools 1 609 929 U13 | (9.12.09)
Avoid any weakening and damage whatsoever of the
pneumatic tool, e.g., through:
– Imprinting or engraving,
– Retrofitting measures not approved by the manufactur-
er,
– Guiding along templates manufactured of hard materi-
al, e.g. steel,
– Dropping on or sliding over the floor,
– Using as a hammer,
– Applying any kind of force.
Make sure to check whatever is below or behind your
workpiece. Do not shoot staples (GTK 40) or brads
(GSK 50) into walls, ceilings or floors, when persons are
behind them. The fasteners can burst through the work-
piece and injure someone.
Do not shoot a staple (GTK 40) or brad (GSK 50) on al-
ready driven-in fasteners. This could cause the fastener to
deform, the fasteners could become jammed or the pneu-
matic tool could move uncontrolled.
When the pneumatic tool is used under cold ambient con-
ditions, the first staples (GTK 40) or brads (GSK 50) are
driven in slower than usual. Once the pneumatic tool has
warmed up during working, normal operating speed will
be regained.
Avoid blank shots in order to reduce the wear of the im-
pact striker.
For longer work breaks or after finishing work, discon-
nect the pneumatic tool from the air supply and empty
the magazine.

When not using the pneumatic tool for a longer period of
time, cover steel parts with a fine oil coating. This pre-
vents the formation of rust.
Maintenance and Service
Maintenance and Cleaning
Disconnect the air supply before making any
adjustments, changing accessories, or plac-
ing the pneumatic tool aside. This safety
measure prevents accidental starting of the
pneumatic tool.
If the pneumatic tool should fail despite the care taken in
manufacture and testing, repair should be carried out by
an authorised customer services agent for Bosch power
tools.
In all correspondence and spare parts orders, please al-
ways include the 10-digit article number given on the type
plate of the pneumatic tool.
f Have maintenance and repair work carried out only
through qualified persons. This will ensure that the
safety of the pneumatic tool is maintained.
An authorized Bosch after-sales service agent will carry
out this work quickly and reliably.
Lubricating the Pneumatic Tool (see figure K)
When the pneumatic tool is not connected to a mainte-
nance unit, it must be lubricated at regular intervals:
– For light-duty use 1x per day.
– For heavy-duty use 2x per day.
Apply 2–3 drops of lubricant into air connector 6. Do not
apply too much lubricant, which could then accumulate in
the pneumatic tool and be emitted via air outlet 4.
Use only the lubricants recommended by Bosch.
– SAE 10 mineral engine oil (for use at very cold ambient
conditions)
– SAE 20 mineral engine oil
Observe all applicable environmental regulations when
disposing of old grease and solvents.
