• Due to our continuing programme of research and development, the specifications herein are subject to change without notice.
• Specifications may differ from country to country.
• The declared vibration emission value has been measured in accordance with the standard test method and may be used for comparing one tool with another.
• The declared vibration emission value may also be used in a preliminary assessment of exposure.
WARNING:
• The vibration emission during actual use of the power tool can differ from the declared emission value depending on the ways in which the tool is used.
• Be sure to identify safety measures to protect the operator that are based on an estimation of exposure in the actual conditions of use (taking account of all parts of the
operating cycle such as the times when the tool is switched off and when it is running idle in addition to the trigger time).
