Battery

-NOTE-

The battery is supplied partially charged. Completely charge the battery before using your power tool for the first time.

Battery with lithium-ion technology

Total discharge protection

The "Electronic discharge protection function" protects the LI battery against total discharge. Should the battery discharge, the power tool is switched off by a protective circuit. The power tool stops operating.

-WARNING-

Do not continue to press the On/Off switch after an automatic shutdown of the power tool.

The battery could be damaged.

Temperature-dependent overload protection

The LI battery is equipped with NTC temperature monitoring which only permits charging within a temperature range of 5^ - 45^ . This ensures long battery service life.

Special notes on batteries with NiMH cells

The power of NiMH batteries drops noticeably at ambient temperatures below 0^ C or over 45^ C .

Even when not in use, NiMH batteries should be recharged roughly every 4 months to ensure that they continue to work at full capacity.

After each tenth charging operation, NiMH batteries should be left in the charger for an extra hour to balance out differences in the capacities of the individual cells.

Because of the danger of self-discharging, NiMH batteries should be stored at ambient temperatures of between 0^ and 25^ where possible.

Battery care

Never charge batteries at temperatures lower than 5^ or higher than 45^ .

Never charge batteries in an environment with high air humidity or a high ambient temperature.

If the batteries are not used for a prolonged period, store them partially charged in a cool place.

IMPORTANT! Batteries will also self-discharge while the equipment is not in use. Charge the batteries regularly to prevent this.

Or even better: Insert the battery into the charger while it is plugged into the mains and ready for operation, as the charger switches to trickle charge when the charging process is completed. This is the best course of action with regard to the service life of the battery and in order to keep it fully operational.

Do not leave the battery in the charger when the charger is not ready for operation.

Charge the battery regularly to ensure maximum service life. This is especially important if you notice that the device is no longer functioning at full power.

To ensure maximum service life, do not recharge the battery immediately when it has only been in use for a short period. If possible, wait until it has reached its lower capacity limit before recharging it.

Try to avoid causing the machine to jam. When this happens, it requires an excessive amount of energy, which means that the battery becomes discharged sooner and is subject to higher wear.

If you notice that you have to charge the battery more and more frequently, it is spent and must be replaced.

Observe the instructions for disposal.

Workplace lighting (optional)

The lamp 7 allows you to cast more light on your working area where lighting conditions are unfavourable.

The lighting switches on automatically when you press the On/Off switch VI.

If the rotational direction switch V is in centre position, the lamp can be used without rotational movement of the driver.

Operating tips

Apply the power tool to the screw only when it is switched off.

Rotating tool inserts may slip.

After working for a long time at low speed, you should run the power tool for approx. 3 minutes at maximum speed in idle to allow it to cool.

Drilling

Always select the speed to suit the material in question and the drill bit diameter.

Fixing screws

Before screwing larger, long screws into hard materials, it is advisable to predrill a pilot hole with the core diameter of the thread to approx. 2/3 of the screw length.

Thread cutting

We recommend the use of machine thread taps.

Lightly oil the thread tap.
Select low speed and 1st gear.
- Cut in clockwise direction, stop, remove in anticlockwise direction.

-NOTE-

Always work at low speed when thread cutting. This prevents the thread tap breaking off.

5. Tools and accessories

When drilling metal, use only sharpened HSS drill tips (HSS=High-Speed Steel) which are in perfect condition.
