ers switch off when the first cells have reached full charge,
the other partly charged cells do not receive the full
charge. The user becomes aware of this effect in the
form of inadequate battery capacity.
This effect can be eliminated by applying a conditioning
charge. During this procedure, the charger supplies a
small current over several hours and monitors the tem-
perature of the battery in order to avoid overheating the
battery. Depending on its condition, the battery will take
6 (fully charged batteries) to 12 hours (empty batteries)
to reach full charge.
The conditioning charge begins when the battery pack
is inserted in the charger and secondly, the condition-
ing mode button
is pressed for approx. 2 seconds.
The yellow LED lights while the battery is being charged
in conditioning mode.
Conditioning charge mode should not be used more
than once per month as battery capacity may otherwise
be negatively affected.
Battery (accessory)
Before a battery is used for the first time, it must
be charged for 24 hours in normal mode or for up to 12
hours in conditioning mode in order to permit "form-
ing" of the battery cells.
– At low temperatures: Battery performance drops at
low temperatures. Store batteries at room tempera-
ture when not in use.
– At high temperatures: Do not store batteries where
they may be subjected to high temperatures (e.g.
exposed to the sun, at a window, behind a car wind-
screen or on a radiator).
– Never fully discharge a battery. Recharge the battery
as soon as its performance drops noticeably. When
approaching total discharge, the cells, which reach a
state of complete discharge first (due to slight differ-
ences in their condition), will be damaged by the cur-
rent still being drawn from the other cells.
Care and maintenance
When conducting care and maintenance work
always pull out the mains plug.
Care of the charger
The outer housing of the charger is made from impact-
resistant plastic.
Clean the outside of the charger at regular
intervals using a slightly damp cloth. Do not use a spray,
steam pressure cleaning equipment or running water
for cleaning. This may negatively affect the electrical
safety of the charger. Do not use cleaning agents which
contain silicone.

Never operate the charger when the ventilation
slots are blocked. Clean the ventilation slots carefully
using a dry brush. Do not permit foreign objects to enter
the interior of the charger.
Take care of your batteries. If necessary, use a dry cloth
to clean the contacts.
Maintenance
Check all external parts of the charger for damage
at regular intervals and check that all controls operate
faultlessly. Do not operate the charger when parts are
damaged or when the controls do not function fault-
lessly. When necessary, your electric tool should be
repaired at a Hilti service centre.
