8.1 Care of the tool
The outer casing of the tool is manufactured from impact-resistant plastic. The grip sec-
tion and supply cord protective sleeve are manufactured form an elastomer material.
Never operate the tool if its ventilation slots are blocked. Clean the ventilation slots
carefully with a dry brush. Do not allow foreign objects to enter the interior of the tool.
Clean the outside surfaces of the tool with a damp cloth at regular intervals. Do not
use a spray, steam cleaning equipment or running water for cleaning. This could neg-
atively affect the electrical safety of the tool. Always keep the grip surfaces of the tool
free from oil and grease. Do not use cleaning agents which contain silicone.
8.2 Maintenance
Check all external parts of the tool for damage at regular intervals and check that all
operating controls function faultlessly. Do not operate the tool when parts are dam-
aged or when operating controls do not function faultlessly. The tool should be repaired
at a Hilti service center.
Repairs to the electrical section of the tool may be carried out by trained electrical
specialists only.
8.3 Checking the tool after care and maintenance
After cleaning or maintenance, check that all guards or other protective devices are
fitted and that they function faultlessly.
