Tips
When sawing lightweight materials, take into account
u
the statutory provisions and recommendations of the
material manufacturers.
Before sawing into wood, chipboard, building materials,
etc., check for any foreign objects such as nails, screws, etc.
and use a suitable saw blade.
Switch on the power tool and guide it towards the workpiece
you wish to work on. Place the base plate (2) on the surface
of the workpiece and saw through the material applying even
pressure and feed. Switch the power tool off once you have
finished your work.
Switch the power tool off immediately if the saw blade jams.
Widen the sawing gap slightly with a suitable tool and pull
the power tool out.
Swivelling and removable base plate (see figures D−E)
Thanks to its mobility, the base plate (2) adopts the required
angle position of the surface.
Depending on the application and the saw blade being used,
the base plate (2) can be moved continuously in length dir-
ection to different settings.
Loosen the screws (13) with the hex key (5) and slide the
base plate (2) into the desired position. Re-tighten the
screws and check whether the base plate is fixed in place.
Plunge cutting (see figure F)
Plunge cuts may only be applied to soft materials,
u
such as wood, gypsum board, etc. Do not plunge cut
metal materials.
For plunge cutting, use only short saw blades.
Place the power tool so that the edge of the base plate (2)
rests on the workpiece, without the saw blade (1) touching
the workpiece, and switch it on. When using power tools
with stroke rate control, select the maximum stroke rate.
Press the power tool firmly against the workpiece and allow
the saw blade to plunge slowly into the workpiece.
As soon as the base plate (2) rests fully on the workpiece,
continue sawing along the required cutting line.
For particular jobs, the saw blade (1) can also be fitted after
being turned 180° in order to operate the power tool the
other way around.
Flush sawing (see figure G)
Protruding components such as water pipes, for example,
can be cut directly at the wall using elastic bi-metal saw
blades.
Ensure that the saw blade is always longer than the
u
diameter of the workpiece. There is a risk of kickback.
Place the saw blade directly against the wall and bend it
slightly by applying lateral pressure to the power tool until
the base plate is flush with the wall. Switch on the power tool
and saw through the workpiece applying consistent lateral
pressure.
Bosch Power Tools
Utility hook (see figure H)
Your power tool is equipped with a utility hook (6) for
hanging it, e. g., from a ladder. Simply fold out the utility
hook to the required position.
When the power tool is hung up, take care that the
u
saw blade is protected from accidental contact. This
poses a risk of injury.
Fold the utility hook (6) in again when you want to begin
work with the power tool.
Coolant/lubricant
As the material heats up along the cutting line when cutting
metal, you should apply coolant or lubricant.

Maintenance and Service

Maintenance and Cleaning

Remove the battery from the power tool before carry-
u
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.
To ensure safe and efficient operation, always keep
u
the power tool and the ventilation slots clean.
Carefully clean the saw blade receptacle with a soft cloth. To
do so, remove the saw blade from the power tool. Keep the
saw blade receptacle operational using suitable lubricants.
If the power tool becomes very dirty, this can lead to serious
faults. For this reason, do not cut materials which generate
large quantities of dust from below or overhead.
