Adjusting the Depth Stop (see figure F)
The driving depth of the staples (GTK 40) or brads
(GSK 50) can be set with thumbwheel 3.
– Empty the magazine 8.
(See "Emptying the Magazine", page 15)
– Nails are driven in too deeply:
To reduce the driving depth, turn thumbwheel 3 in anti-
clockwise direction.
or
Nails are not driven in deep enough:
To increase the driving depth, turn thumbwheel 3 in
clockwise direction.
– Refill the magazine.
(See "Loading the Magazine", page 15)
– Test the new driving depth on a test workpiece.
Repeat the worksteps as required.

Maintenance and Service

Maintenance and Cleaning

Disconnect the air supply before making
any adjustments, changing accessories,
or placing the pneumatic tool aside. This
safety measure prevents accidental start-
ing 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.

Maintenance Schedule

Always keep air outlet 4, discharge lock-off 2 and trigger
10 clean and free of foreign material (dust, chips, sand,
etc).

Clearing Jams
Single staples (GTK 40) or brads (GSK 50) can become
jammed in the shot duct. If this should occur frequently,
please contact an authorised service agent for Bosch pow-
er tools.
Note: When the driver blade does not return after clearing
a jam, please contact an authorised service agent for
Bosch power tools.
GTK 40 (see figures G1–G3)
– Empty the magazine 8.
(See "Emptying the Magazine", page 15)
– Press clamping lever 12 down so that the shot duct
opens.
– Remove the jammed staple. For this, us a pair of pliers,
if required.
– When driver blade 21 is extended, push it back into the
piston using a lubricated screwdriver or other suitable
lubricated object.
– Lubricate the shot duct with 2–3 drops of engine oil
(SAE 10 or SAE 20).
– Close the shot duct, hang the clip of clamping lever 12
into the hooks on the shot duct and then push the
clamping lever up again.
– Refill the magazine.
(See "Loading the Magazine", page 15)
GSK 50 (see figure H)
– Empty the magazine 8.
(See "Emptying the Magazine", page 15)
– With the magazine open, remove the jammed brad. For
this, us a pair of pliers, if required.
– When driver blade 21 is extended, push it back into the
piston using a lubricated screwdriver or other suitable
lubricated object.
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.
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:
Clean the magazine 8. Remove any plastic or wood chips
that may accumulate in the magazine during operation.
Explanation
Prevents the accumulation of dirt/ debris and moisture in the
pneumatic tool.
Ensures the lubrication of the pneumatic tool.
Prevents a staple (GTK 40) or brad (GSK 50) from becoming
jammed.
Promotes your work safety and efficient usage of the pneu-
matic tool.
Reduces the wear of the pneumatic tool.
Prevents the accumulation of dirt/ debris and moisture in the
pneumatic tool.
– Lubricate the shot duct with 2–3 drops of engine oil
(SAE 10 or SAE 20).
– Refill the magazine.
(See "Loading the Magazine", page 15)
Changing the Workpiece Protector (see figure I)
The workpiece protector 1 at the end of the discharge lock-
off 2 protects the workpiece until the pneumatic tool is cor-
rectly placed for the driving procedure.
The workpiece protector can be removed and replaced.
– Pull the workpiece protector from the discharge lock-
off.
– Push the new workpiece protector via the open end
over the discharge lock-off.
GSK 50: This pneumatic tool allows for a spare workpiece
protector to be stored at the top side of magazine 8. For
this, push the workpiece protector into the depot 22.
Adjustable Air-outlet cap (see figure J)
With the adjustable exhaust cap at the air outlet 4, it is pos-
sible to deflect the exhaust air away from yourself or the
workpiece.
Transport and Storage
For transport, disconnect the pneumatic tool from the air
supply; especially when using ladders or moving in an unu-
sual stance or posture.
At the workplace, carry the pneumatic tool only by the han-
dle 5 and with the trigger 10 released.
Always store the pneumatic tool disconnected from the air
supply and at a clean and dry location.
When not using the pneumatic tool for a longer period of
time, cover steel parts with a fine oil coating. This prevents
the formation of rust.
– 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.
Clean the pneumatic tool in regular intervals using com-
pressed air.
Action
– Open the drain valve.
– Fill lubricator with the recommended lubricants.
(See "Lubricating the Pneumatic Tool", page 16)
