• When sawing in walls or floors be aware
of the location of pipework and wiring.
Always hold the tool by its handle.
• Avoid overloading.
Prior to operation:
• Mount the appropriate type of saw blade.
Use narrow saw blades for cutting curves.
Use flexible bimetal saw blades for hard-to-reach
positions (e.g. close to walls, etc.).
Switching on and off (fig. A)
• To run the tool, press the variable speed switch (1).
The pressure exerted on the variable speed switch
determines the tool speed.
• 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.
• Always switch off the tool before unplugging.
Cutting wood (fig. A)
• Clamp the workpiece securely and remove all
nails and metal objects.
• Holding the tool with both hands, work with the
saw shoe (6) pressed against the workpiece.
Plunge cutting in wood
• Rest the saw shoe (6) 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 (6) on the workpiece and make sure
that the blade is positioned on the cutting line.
If necessary, e.g. in confined 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 firmly
against the workpiece.

• 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.
• Whenever possible, connect a dust extraction
device designed in accordance with the relevant
regulations regarding dust emission.
Cutting metal (fig. A)
• 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 film 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.
Consult your dealer for further information on the
appropriate accessories.

E
operate over a long period of time with a minimum
of maintenance. Continuous satisfactory operation
depends upon proper tool care and regular cleaning.
Lubrication
• If the tool will not be used for a long period of
time, coat the saw blade with a little oil
(e.g. machine oil).
