blade release button depressed and use a screwdriver to turn
the location pin into the correct position.
Removing

N
the blade downward through 90°.

Use
Warning! Let the tool work at its own pace. Do not overload.
Charging the battery (fig. A)
The battery needs to be charged before first use and
whenever it fails to produce sufficient power on jobs that
were easily done before. When charging the battery for the
first time, or after prolonged storage, it will only accept an
80% charge. After several charge and discharge cycles, the
battery will attain full capacity. The battery may become warm
while charging; this is normal and does not indicate a problem.
Warning! Do not charge the battery at ambient temperatures
below 4 °C or above 40 °C. Recommended charging
temperature: approx. 24 °C.
Using the 3 hr charger
To charge the battery (4), remove it from the tool.
N
Slide the charger receptacle (6) onto the battery.
N
Plug in the charger (5).
N
After approx. 3 hours of charging, the battery will be sufficiently
charged for use in regular applications. After approx. 6 hours
of charging, the battery will be fully charged.
Remove the charger receptacle from the battery.
N
Using the 1 hr charger
To charge the battery (4), remove it from the tool and
N
insert it into the charger (7). The battery will only fit into
the charger in one way. Do not force. Be sure that the
battery is fully seated in the charger.
Plug in the charger.
N
Check if the red charging indicator (8) lights up. If the
N
green end of charge indicator (9) lights up now instead,
the battery is too hot and cannot be charged. If this
happens, remove the battery from the charger, let the
battery cool down for approx. 1 hour and re-insert it.
6
After approx. 1 hour of charging, the red charging indicator (8)
will stop lighting and the green end of charge indicator (9) will
light up. The battery is now fully charged.
Remove the battery from the charger.
N
Switching on and off (fig. F)
To switch the tool on, push the two lock-off button (2) into
N
the unlock position and squeeze the variable speed switch
(1).
To switch the tool off, release the variable speed switch.
N
Sawing (fig. G)
If possible, always hold the tool with both hands.
N
Let the blade run freely for a few seconds before starting
N
the cut.
Apply only a gentle pressure to the tool while performing
N
the cut.
Use the same back and forth movement you would
N
employ with a normal hand saw. This enables a quicker
and cleaner cut.
Hints for optimum use
Sawing wood
Clamp the workpiece securely and remove all nails and
N
metal objects.
When splintering is to be minimised, e.g. when cutting
N
laminates, clamp a piece of scrap wood or hardboard to
both sides of the workpiece and saw through this sandwich.
Sawing metal
Be aware that sawing metal takes much more time than
N
sawing wood.
Use a saw blade suitable for sawing metal. Use a fine-
N
tooth saw blade for ferrous metals and a coarser saw
blade for nonferrous metals.
When cutting thin sheet metal, clamp a piece of scrap
N
wood to the back surface of the workpiece and cut
through this sandwich.
Spread a film of oil along the intended line of cut.
N
Cutting branches
Cut downward and away from your body.
N
Make the cut close to the main branch or tree body.
