Before Use - Hilti GX 90-WF Operating Instructions Manual

NOTE
The sound pressure and vibration values given in these instructions have been measured in accordance with a
standardized test and may be used to compare one fastening tool with another. They may be used for a preliminary
assessment of exposure. The data given represents the main applications of the fastening tool. However, if the
fastening tool is used for different applications, with different accessories or is poorly maintained, the data may
vary. This may significantly increase the level of exposure over the total working period. An estimation of the level of
exposure should also take into account the periods of time when the tool is not actually in use. This may significantly
reduce the level of exposure over the total working period. Prescribe additional safety measures to protect the operator
en
from the effects of noise and/or vibration, such as: maintaining the fastening tool and its additional equipment or
accessories, keeping the hands warm, reorganization of work patterns.
