STARTING UP
Before starting-up the tool, ensure that:
- the packaging is complete and does not show signs of having been
damaged during storage or transport;
- the tool is complete; check that the number and type of components
comply with that reported in this instruction booklet;
- the power supply and socket outlet can support the load reported in the
table and that indicated on the tool identification plate reproduced and
explained on page 11.
ASSEMBLING THE TOOL
CHARGE THE BATTERY (H)
The new battery is supplied uncharged therefore it must be charged before
use. The new battery requires at least ten charge-uncharge cycles before pro-
viding the services indicated on the label.
To charge proceed as follows:
- insert the battery charger plug in the power socket;
- insert the battery in the specific housing (15) making sure that the rib on the
battery side corresponds to the groove on the battery housing;
- check that the red light (14) is on; charging is complete when the green light
goes on.
Warning: only use the battery charger in dry, clean areas away from heat
sources and flammable substances!
BATTERY ASSEMBLY (A)
Insert the battery (9) in the lower part of the handle (7) pushing upwards until
the fastening device clicks. Make sure that voltage is suitable for tool opera-
tions.
BIT AND INSERT ASSEMBLY AND DISMANTLING

chosen bit or insert;
2 -tighten the chosen tool between the jaws by screwing in the chuck;
3 -make sure the tool does not rotate off-centre;
4 -follow the instructions in reverse order to dismantle.
ROTATION DIRECTION SELECTION (C)
