Dust Extraction; Cutting Metal - Berner BRS-1200 Bedienungsanleitung/Sicherheitshinweise

E N G L I S H
• Push the release lever (6) down.
• Slide the saw shoe (5) into the desired position.
• Push the lever up to secure the shoe in place.
Setting the pendulum stroke (fi g. D)
The adjustable pendulum stroke guarantees a perfect
cutting stroke for different materials. The tool can be used
in the following operating modes:
Straight reciprocating motion: for cutting metal
and tubes and for fi nishing wood.
Orbital motion: for fast cutting of wood.
• Turn the selector (3) into the required position aligning
the mark (9) with the arrow (10).
Instructions for use
• Always observe the safety instructions and
applicable regulations.
• Ensure the material to be sawn is secured
in place.
• Apply only a gentle pressure to the tool
and do not exert side pressure on the
saw blade. If possible, work with the saw
shoe pressed against the workpiece. This
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.).
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.
Setting the electronic sawing speed (fi g. A)
The speed control dial (2) can be used for advance setting
of the required range of speed.
• Turn the electronic speed control dial to the required
level. The required setting depends on the thickness
and kind of material.
• Use high speeds for sawing soft materials such as
wood. Use low speeds for sawing metal.
After using the tool for an extended period on
low speed settings, run it for approx. 3 minutes
on maximum no-load speed.
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. E)
• 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.
