7 Care and maintenance
CAUTION
Disconnect the supply cord plug from the power out-
let.
7.1 Care of the appliance
The outer casing of the appliance is made from impact-
resistant plastic.
Clean the exterior of the appliance at regular intervals with
a slightly damp cloth or a dry brush. Do not use a spray,
steam pressure cleaning equipment or running water for
cleaning. This may negatively affect the electrical safety
of the appliance. Always keep the appliance free from oil
and grease. Do not use cleaning agents which contain
silicone.
7.2 Maintenance
WARNING
Repairs to electrical parts and replacement of the
supply cord may be carried out only by trained elec-
trical specialists.
Check all external parts of the appliance for damage
at regular intervals and check that all controls operate
faultlessly. Do not operate the appliance when parts are
damaged or when the controls do not function correctly.
If necessary, the power tool should be repaired by Hilti
Service.
7.3 Care of the battery
Keep the electrical contacts free from dust, oil and
grease.
If necessary, use a clean cloth to clean the contact
surfaces.
If battery capacity drops below an acceptable level after
many periods of use and recharging, we recommend
having it checked by Hilti.

The burning of plastic components generates toxic fumes which may present a health hazard.
Batteries may explode if damaged or exposed to very high temperatures, causing poisoning, burns, acid burns or
environmental pollution.
Careless disposal may permit unauthorized and improper use of the equipment. This may result in serious personal
injury, injury to third parties and pollution of the environment.
