- With your thumb, position switch "G" of the sliding plate (21) as shown in dia. (extension
"H"). At the same time, with your middle finger, secure the transmission lever (25) on the
backside of the sliding plate to prevent unhinging or slipping away (see dia. "sliding
plate").
- In this position, the sliding plate (21) is, now, to be pushed through the leads "K" into the
chassis.
- Switch "G" must remain in the position described above.
- Shortly before the lower edge of the sliding plate (21) reaches lead "L", the cradle "J"

Power supply and battery test
After accomplishing the aforementioned electric test (i.e. in a discharged mode) recharge the
appliance for a period of 15 minutes, then remove it from the power supply.
•Important! Oil the cutter system.
•Let the appliance run into a discharged state. After the motor has come to a full stop, the
display must indicate "0".
•Switch off the appliance.
•Recharge the appliance control the energy or power consumption respectively by means of
an ammeter (measuring range 0 to 200 mA max.) or a watt meter (measuring range 0 to
200 watts max.). After 90 minutes max. the recharging process is accomplished, and the
appliance switches to the recharged state (ammeter and watt meter needle respectively fall
into the range of "0").
If these values are maintained within this range, the P.C.B. is functional.
Attention: If the appliance is removed from the power supply for more than 10 minutes after
total recharge is accomplished, a boost charge of approx. 5 minutes will take place
before the appliance switches over to the recharged state.
