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.
 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.

Maintenance Schedule

Always keep air outlet 4, discharge lock-off 2 and trigger
10 clean and free of foreign material (dust, chips, sand,
etc).
Measure
Draining the exhaust filter daily.
Keeping the lubricator filled at all times.

Correction of Malfunctions

Problem
The pneumatic tool is ready for operation, but no
staples (GTK 40) or brads (GSK 50) are dis-
charged.
The staples (GTK 40) or brads (GSK 50) are dis-
charged very slowly and with too little pressure.

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.
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.
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.
jammed.
Promotes your work safety and efficient usage of the pneumat-
ic tool.
Reduces the wear of the pneumatic tool.
Prevents the accumulation of dirt/ debris and moisture in the
pneumatic tool.
Cause
A staple (GTK 40) or a brad (GSK 50) has become jammed in
the shot duct.
The magazine slider is 11 defective.
The spring of the magazine slider is too week or defective.
The fasteners being used are not permitted.
The magazine 8 is empty.
The rated pressure of the compressed-air supply is too low.
The driver blade is damaged.
The sealing ring of the piston is worn or damaged.
The buffer is worn.
The length and diameter of supply-air hose 17 do not corre-
spond with the data of this pneumatic tool.
The supply-air hose 17 is bent/creased.
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.
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)
– Blow out the mechanism of the magazine/magazine slider daily with
compressed air.
– Blow out the mechanism of the discharge lock-off daily with com-
pressed air.
– Apply 2–3 drops of lubricant into air connector 6.
(See "Lubricating the Pneumatic Tool", page 16)
– Open the drain valve of the compressor tank.
Corrective Measure
– Clear the jam.
(See "Clearing Jams", page 15)
– Clean and lubricate the magazine slider 11 as required and make
sure that the magazine 8 is not dirty/soiled.
