Bosch GNA 3,5 Professional Original Instructions Manual page 5

Keep cutting tools sharp and clean. Properly main-
u
tained cutting tools with sharp cutting edges are less
likely to bind and are easier to control.
Use the power tool, accessories and tool bits etc. in
u
accordance with these instructions, taking into ac-
count the working conditions and the work to be per-
formed. Use of the power tool for operations different
from those intended could result in a hazardous situation.
Keep handles and grasping surfaces dry, clean and
u
free from oil and grease. Slippery handles and grasping
surfaces do not allow for safe handling and control of the
tool in unexpected situations.
Service
Have your power tool serviced by a qualified repair
u
person using only identical replacement parts. This
will ensure that the safety of the power tool is maintained.
Safety instructions for nibblers
This power tool is not suitable for bench-mounted use.
u
It must not be clamped into a vice or fastened to a work-
bench, for example.
Wear protective gloves during work and pay particu-
u
lar attention to the cord. Sharp burrs develop on the cut
sheets; these can cause injury or damage the cord.
Products sold in GB only:
Your product is fitted with an BS 1363/A approved electric
plug with internal fuse (ASTA approved to BS 1362).
If the plug is not suitable for your socket outlets, it should be
cut off and an appropriate plug fitted in its place by an au-
thorised customer service agent. The replacement plug
should have the same fuse rating as the original plug.
The severed plug must be disposed of to avoid a possible
shock hazard and should never be inserted into a mains
socket elsewhere.
Hold the power tool firmly with both hands and make
u
sure you have a stable footing. The power tool can be
more securely guided with both hands.
