8.3 Care of the Li-ion battery
Avoid entrance of moisture.
Charge the battery fully before using it for the first time.
In order to achieve maximum battery life, stop discharging the
battery as soon as a significant drop in performance is noticed.
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.
Check all external parts of the power tool for damage at regular
intervals 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.
