prevents damage to the blade and stops
the tool from jerking and vibrating.
• When sawing in walls or fl oors be aware of
the location of pipework and wiring. Always
hold the tool by its handle.
• Avoid overloading. Let the blade run freely
for a few seconds before starting the cut.
Never switch on the tool when the saw
blade is jammed in the workpiece or in
contact with the material.
Prior to operation:
• Mount the appropriate type of saw blade. Use narrow
saw blades for cutting curves. Use fl exible bimetal
saw blades for hard-to-reach positions (e.g. close to
walls, etc.).
Proper Hand Position (fi g. D, E)
WARNING: To reduce the risk of serious
personal injury, ALWAYS use proper hand
position as shown.
WARNING: To reduce the risk of serious
personal injury, ALWAYS hold securely in
anticipation of a sudden reaction.
Proper hand position requires one hand on the back
handle (7), with the other hand on the front grip (5).
Switching on and off (fi g. A)
• To run the tool, press the variable speed switch (1).
The pressure exerted on the variable speed switch
determines the tool speed.
• To stop the tool, release the switch. Always switch off
the tool when work is fi nished and before unplugging.
Cutting wood
• Clamp the workpiece securely and remove all nails
and metal objects.
• Holding the tool with both hands, work with the saw
shoe pressed against the workpiece.
Plunge cutting in wood (fi g. C)
• Rest the saw shoe on the workpiece in such a position
that the blade forms an appropriate angle for the
plunge cut.
• Switch the tool on and slowly feed in the blade. Make
sure that the saw shoe remains in contact with the
workpiece at all times.
Pocket cuts
• Measure and mark the required pocket cut.
• Using a narrow saw blade rest the bottom of the saw
shoe on the workpiece and make sure that the blade
is positioned on the cutting line. If necessary, e.g. in
confi ned spaces, use the outer edge of the saw shoe
as your guideline.
• Switch on the tool and feed the blade into the material
at full speed, holding the tool fi rmly against the
workpiece.
Dust extraction
• When the tool is used indoor for extended periods
of time, use a suitable dust extractor designed in
compliance with the applicable Directives regarding
dust emission.
Cutting metal
• When cutting thin metal always stabilize the
workpiece with wood on both sides. This guarantees
clean cuts and prevents damaging of the material.
• For long, straight cuts draw a line on the workpiece.
• Apply a thin fi lm of lubricant along the cutting line,
switch on the tool and follow the cutting line.
Cutting plastics
• Always work at reduced speed. Carry out a test cut
to check whether the material is sensitive to heat.
Cutting masonry
When sawing asbestos cement hazardous
dust may be produced. Follow the statutory
guidelines and observe the recommendations
issued by the asbestos cement manufacturers.
Sawing up to a projecting edge (fi g. D)
• Using a conventional blade installed upside down,
cut up to the projected edge.
Parallel cutting (fi g. E)
With the blade installed in the horizontal orientation, the
tool can be used for parallel cutting close to fl oors, walls
or ceilings.
• Make sure that the saw shoe remains in contact with
the workpiece at all times.
Consult your dealer for further information on the
appropriate accessories.
Maintenance
Your Berner power tool has been designed to operate
over a long period of time with a minimum of maintenance.
Continuous satisfactory operation depends upon proper
tool care and regular cleaning.
