NOTE
If use of the power tool continues, battery discharge is stopped automatically
(indicated by LED 1 blinking) before the battery cells suffer damage.
Charge the battery with the Hilti charger approved for use with Li-ion
batteries.
NOTE
– A conditioning charge (as is required with NiCd or NiMH batteries) is
not necessary.
– Interruption of the charging procedure has no negative effect on
battery life.
– Charging can be started at any time with no negative effect on battery
life. There is no memory effect (as with NiCd or NiMH batteries).
– For best results, batteries should be stored fully charged in a cool dry
place. Avoid charging the battery in places subject to high ambient
temperatures (e.g. at a window) as this has an adverse effect on
battery life and increases the rate of self-discharge.
– If the battery no longer reaches full charge, it may have lost capacity
due to aging or overstressing. It is possible to continue working with a
battery in this condition but it should be replaced in good time.
8.4 Maintenance
WARNING
Repairs to the electrical section of the power tool may be carried out
only by trained electrical specialists.

and check that all controls operate faultlessly. Do not operate the power
tool if parts are damaged or when the controls do not function faultlessly. If
necessary, the power tool should be repaired by Hilti Service.
8.5 Checking the power tool after care and maintenance
After carrying out care and maintenance work on the power tool, check that
all protective and safety devices are fitted and that they function faultlessly.
