Ɣ Using the device for longer periods can cause poor
circulation in the hands due to vibrations. A general
period of use cannot be set, because this depends on
several influencing factors:

(frequently cold fingers, tingling sensation in the fin-
gers)
Ɣ Low ambient temperature. Wear warm gloves to
protect your hands.
Ɣ Holding the device too tightly hindering blood circu-
lation.
Ɣ Continuous operation is more harmful than opera-
tion interrupted by work breaks.
You should see a doctor if using the device regularly
and for lengthy periods of time, and in the event of re-
peated occurrences of symptoms such as tingling in
the fingers or cold fingers.
