After longer periods of work at low stroke rate,
the machine can heat up considerably. Remove
the saw blade from the machine and allow the
machine to cool down by running it for approx.
3 minutes at maximum stroke rate.

Working Advice

Tips
When sawing light building materials, ob-
serve the statutory provisions and the rec-
ommendations of the material suppliers.
Note: Do not cover the ventilation slots under-
neath the tool holder with the hand.
Check wood, press boards, building materials,
etc. for foreign objects such as nails, screws or
similar, and remove them, if required.
Switch the machine on and guide it toward the
workpiece. Position the footplate 2 onto the sur-
face of the work and saw through the material ap-
plying uniform contact pressure and feed. After
completing the working procedure, switch the
machine off.
If the saw blade should jam, switch the machine
off immediately. Widen the gap somewhat with a
suitable tool and pull out the machine.
Plunge Cutting (see figures C–D)
The plunge cutting procedure is only suita-
ble for treating soft materials such as wood,
plaster board or similar! Do not work metal
materials with the plunge cutting procedure!
Use only short saw blades for plunge cutting.
Place the machine with the edge of the footplate
2 onto the workpiece and switch on. For power
tools with stroke speed control, set the maxi-
mum stroke speed. Press the power tool firmly
against the workpiece and allow the saw blade to
slowly plunge into the workpiece.
As soon as the footplate 2 fully lays on the sur-
face of the workpiece, continue sawing alongside
the desired cutting line.
Bosch Power Tools
Flush Cuts (see figure E)
Using elastic bimetal saw blades, items still at-
tached to a wall (e. g. projecting building ele-
ments such as water pipes, etc.) can be sawn off
flush at the wall.
Pay attention that the saw blade always ex-
tends beyond the diameter of the material
being worked. There is danger of kickback.
Position the saw blade directly against the wall
and apply some lateral pressure via the tool until
the footplate faces against the wall. Switch the
power tool on and saw through the workpiece,
applying constant lateral pressure.
Coolant/Lubricant
When sawing metal, coolant/lubricant should be
applied alongside cutting line because of the ma-
terial heating up.

Maintenance and Service

Maintenance and Cleaning

Before any work on the machine itself, pull
the mains plug.
For safe and proper working, always keep
the machine and ventilation slots clean.
Cleaning the Saw Blade Holder (see figure F)
Clean the saw blade holder preferably with com-
pressed air or a soft brush. Remove the saw
blade from the power tool for this. Ensure proper
operation of the saw blade holder by applying a
suitable lubricant.
Heavy contamination of the machine can lead to
malfunctions. Therefore, do not saw materials
that produce a lot of dust from below or over-
head.
