8.2 Care of the power tool
CAUTION
Keep the power tool, especially its grip surfaces, clean and free from
oil and grease. Do not use cleaning agents which contain silicone.
The outer casing of the power tool is made from impact-resistant plastic.
Sections of the grip are made from a synthetic rubber material.
Never operate the power tool 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 power tool. Clean the outside of the
power tool at regular intervals with 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 power tool.
8.3 Care of the Li-ion battery
Avoid ingress 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 battery performance is noticed.
NOTE
If use continues, further battery discharge will be stopped automatically
before the battery cells suffer damage.
Charge the battery using an approved charger from Hilti designed 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. Storing the battery in places subject to high ambient
temperatures (e.g. at a window) has an adverse effect on battery life
and increases the rate of self-discharge.
