Nails are not driven in deep enough:
To increase the driving depth, turn thumbwheel 12 in clockwise direc-
tion.
– Refill the magazine.
(See "Loading the Magazine", page 17)
– Test the new driving depth on a test workpiece.
Repeat the worksteps as required.
Removing the Discharge Lock-off
For service or cleaning purposes, the discharge lock-off 2 can be re-
moved.
– Turn thumbwheel 12 in clockwise direction, until the first thread can be
seen.
– Carry out 6 further turns in clockwise direction.
The discharge lock-off 2 can now be pulled off.
– To reinsert again, slide discharge lock-off 2 back into the holes intend-
ed for this, and turn thumbwheel 12 in anticlockwise direction until no
more threads can be seen.
Clearing Jams (see figures G1
Single nails can become jammed in the shot duct. If this should occur fre-
quently, please contact an authorised service agent for Bosch power
tools.

(See "Emptying the Magazine", page 18)
– Press clamping lever 3 down so that the shot duct opens.
– Remove the jammed nail. For this, us a pair of pliers, if required.
– When driver blade 19 is extended, push it back into the piston using a
lubricated screwdriver or other suitable lubricated object.
– Lubricate the shot duct with 2
SAE 20).
– Close the shot duct, hang the clip of clamping lever 3 into the hooks on
the shot duct and then push the clamping lever up again.
– Refill the magazine.
(See "Loading the Magazine", page 17)
Note: When the driver blade does not return after clearing a jam, please
contact an authorised service agent for Bosch power tools.
Changing the Workpiece Protector (see figure H)
The workpiece protector 1 at the end of the discharge lock-off 2 protects
the workpiece until the pneumatic tool is correctly 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.
Note: A spare workpiece protector can be stored at the top side of maga-
zine 10. For this, push the workpiece protector into the depot 9.
Adjustable Air-outlet cap (see figure I)
With the adjustable exhaust cap at the air outlet 4, it is possible to deflect
the exhaust air away from yourself or the workpiece.

Transport and Storage
For transport, disconnect the pneumatic tool from the air supply; espe-
cially when using ladders or moving in an unusual stance or posture.
At the workplace, carry the pneumatic tool only by the handle 7 and with
the trigger 5 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.
Maintenance and Service
Maintenance and Cleaning
Disconnect the air supply before making any adjust-
ments, 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.
In all correspondence and spare parts orders, please always include the
10-digit article number given on the type plate of the pneumatic tool.
Have maintenance and repair work carried out only through quali-
fied 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 J)
When the pneumatic tool is not connected to a maintenance 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 8. Do not apply too much
–
lubricant, which could then accumulate in the pneumatic tool and be emit-
ted 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.
