6.1 Care of the rotary hammer

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 rotary hammer, especially its grip surfaces, clean and free from oil and grease. Do not
use cleaning agents containing silicone.
▶ Never operate the rotary hammer 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 rotary hammer.
▶ Clean the outside of the electric tool at regular intervals with a slightly damp cloth. Do not use a spray,
steam pressure cleaning equipment or running water for cleaning.

6.2 Cleaning the dust shield

▶ Clean the dust shield on the chuck with a dry, clean cloth at regular intervals.
▶ Clean the sealing lip by wiping it carefully and then grease it again lightly with Hilti grease.
▶ It is essential that the dust shield is replaced if the sealing lip is damaged.
6.3 Care of the lithium­ion batteries
Note
Battery discharge is stopped automatically before the battery cells suffer damage.
A conditioning charge of the battery is not necessary.
Interruption of the charging operation has no negative effect on battery life.
Charging can be started at any time with no negative effect on battery life.
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.
▶ Charge batteries fully before using them for the first time.
▶ Do not allow moisture to enter the interior.

6.4 Transport and storage of batteries

WARNING
Risk of fire! Risk of short circuiting.
▶ To avoid short circuits and associated heat generation, lithium-ion batteries should never be stored
or transported in loose, bulk form and without protective measures.
▶ Pull the battery out of its locked position and into the first engagement position.
