related to vibration (such as tingling,
numbness, and white or blue ngers),
seek medical advice as soon as
possible.
Do not smoke during use. Nicotine 2.
reduces the blood supply to the

vibration may cause temporary or
permanent physical injury, particularly
to the hands, arms and shoulders. To
reduce the risk of vibration-related
injury:

vibration effects on the user.
Use tools with the lowest vibration 4.
when there is a choice between
different processes.
Include vibration-free periods each 5.
day of work.
Grip tool as lightly as possible (while 6.
still keeping safe control of it). Let
the tool do the work.
To reduce vibration, maintain the tool 7.
as explained in this manual. If any
