Concerning your safety – Start-up procedure
Avoid operation in closed or partly closed rooms, or ensure ade-
quate ventilation when working in trenches.

3.6.4 Operation in trenches

Applies only to Germany.
The vibratory tamper or the vibratory plate were tested outdoors by
BG Bau (Germany) regarding CO emissions. The tests were car-
ried out in a trench with a width of 1.5 metres, a depth of 3 metres
and a length of 10 metres.
These test showed CO emissions below the occupational exposure
limit (OEL) according to TRGS 900 when operating a maximum of
4 times 15 minutes per shift (8 hours).
For this reason, take care to ensure sufficient ventilation when
operating the vibratory tamper or vibratory plate in more than
shoulder-deep trenches which have a width of less than
1.5 metres, a maximum depth of less than 3 metres or a maximum
length of less than 10 metres.
