CAUTION
Unintentional starting. If the battery is not removed from the power tool there is a risk of the power tool
starting unintentionally while it is being cleaned. This could lead to injury.
▶ Remove the battery from the power tool before beginning cleaning.
▶ Keep the power tool, especially its grip surfaces, clean and free from oil and grease. Do not use cleaning
agents containing silicone.
▶ Never operate the angle grinder when the air vents are blocked. Clean the air vents carefully using a dry
brush. Do not permit foreign objects to enter the interior of the power tool.
▶ Clean the outer surfaces of the power tool with a slightly damp cloth at regular intervals. Do not use a
spray system, pressure jet washer or running water for cleaning as this may negatively affect the electrical
safety of the power tool.
Frequent work on conductive materials (e.g. metal, carbon fiber) may make shorter maintenance
intervals necessary. Take your individual workplace risk assessment into account.
To help ensure safe and reliable operation, use only genuine Hilti spare parts and consumables.

Care of the Li-ion battery
▶ Keep the battery clean and free from oil and grease.
▶ Clean the outer surfaces with a slightly damp cloth at regular intervals. Do not use cleaning agents
containing silicone.
▶ To achieve maximum battery life, stop drawing power from the battery as soon as a significant drop in
the performance of the power tool is noticed.
▶ Charge the batteries using the Hilti chargers approved for use with Li-ion batteries.
7.3
Checks after care and maintenance work
▶ After carrying out care and maintenance, check that all protective and safety devices are fitted and that
they function faultlessly.
7.4
Transport and storage
WARNING
Fire hazard. Risk of short circuiting.
▶ Never store or transport Liion batteries in loose, bulk form.
▶ Pull the battery out of its locked position and into the first engagement position.
▶ Observe the nationally and internationally applicable transport regulations when shipping batteries by
road, rail, sea or air.
Ideally, the battery should be stored in a fully-charged state in a dry place that is as cool as
possible. 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.
If the battery no longer reaches full charge, it may have lost capacity due to aging or overstressing.
It is still possible to work with this battery. You should, however, soon replace the battery with a
new one.
