6.1 Care and maintenance of the power tool
WARNING
Electrical hazards. Improper repairs to electrical parts may lead to serious injuries.
▶ Electrical parts may be repaired only by trained electrical specialists.
▶ Keep the tool, especially its grip surfaces, clean and free from oil and grease. Do not use cleaning agents
containing silicone.
▶ Never operate the power tool 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 tool.
▶ Clean the outside of the 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.
Note
To help ensure safe and reliable operation, use only genuine Hilti spare parts and consumables.
Spare parts, consumables and accessories approved by Hilti for use with the product can be
found at your local Hilti Center or online at: www.hilti.com
6.2 Care of the Li-ion battery
▶ Keep the battery clean and free from oil and grease.
▶ Clean the outer surfaces of the tool with a slightly damp cloth at regular intervals. Do not use cleaning
agents containing silicone.
▶ To achieve maximum battery lifetime, 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.
6.3 Transport and storage
WARNING
Fire hazard. Risk of short circuiting.
▶ Never store or transport Liion batteries in loose, bulk form.
▶ Remove the battery before transporting or storing the drill / driver.
▶ Observe the nationally and internationally applicable transport regulations when shipping batteries by
road, rail, sea or air.
Note
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 lifetime 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.
