• Do not repair the tool at the work site. Always take the tool to a repair shop. Never drag the tool on the ground.
The air port and other openings will become clogged with dirt and debris.
• Compressed air is dangerous. Avoid pointing the hose at any of your co-workers or yourself and never use the
air to clear the worksite or work clothing.
• Do not operate the tool unless the drill steel is pushed against the worked material to avoid premature wear of
parts and reduce the vibration isolation properties of the tool.
