Charge-control Indicator (see main figure)
The battery 6 is fitted with a charge-control indica-
tor 9.
By pressing the button 10, the battery charge can
also be checked when the battery has been
removed, or when the machine is at a standstill
(machine must be switched off for at least 1 minute).
After approx. 4 seconds the battery charge display
automatically turns off.
When the first display element begins to flash (0 –
10 %) the battery is almost empty and must be
recharged.

Before any work on the machine itself, remove
the battery.
Open the quick-change 3 holder by turning the
clamping ring in the direction of the arrow and
holding.
Insert the saw blade 1 as far as it will go and
release the tension ring. The saw blade is fixed
automatically. Check that the saw blade is sitting
firmly (wear protective gloves!)
Only use saw blades with adequate length. The
saw blade has to be longer than the working
piece even when working with the lowest stroke
rate (H). Saw blades can break if hit against the
working piece or the guide shoe.

The saw blade gets worn most in the area just
before the guide shoe. To increase the life of
the saw blade the guide shoe can be moved.
Pull the clamping lever 7 downward and move
the guide bracket to the requested position. Push
the clamping lever up again.

Operating Instructions
If you want to saw a cut into a panelled wall, check
beforehand if there are any electric or other cables
in the area to be sawn (eg. with metal detector).
When sawing, only hold plastic parts of machine.
This will prevent an electric shock should you saw
through a cable.
In order to avoid vibrations press the guide shoe flat
to the working material when sawing.
Sawing metal
F
When sawing into metal start with a low stroke rate,
then increase the stroke rate by depressing the switch.
For plunge cutting, first drill a hole which is slightly
larger than the saw blade and then start to cut.
When sawing into metal apply coolant and lubricant
(oil, paraffin oil) along the cutting line.
Plunge cuts
Plunge cutting is only possible in soft materials.
Switch on machine and rest guide shoe on work-
piece, hold housing firmly with one hand at the top
and with your other hand push upwards on the hand
grip, slowly plungeing in the saw blade.
Dust Protection
Dusts from materials such as lead-containing
coatings, some wood types, minerals and metal
can be harmful to one's health. Touching or
breathing-in the dusts can cause allergic reac-
tions and/or lead to respiratory infections of the
user or bystanders.
Certain dusts, such as oak or beech dust, are con-
sidered as carcinogenic, especially in connection
with wood-treatment additives (chromate, wood
preservative). Materials containing asbestos may
only be worked by specialists.
- Provide for good ventilation of the working
place.
- It is recommended to wear a P2 filter-class res-
pirator.
Observe the relevant regulations in your country
for the materials to be worked.
