injuries, and damage to the tractor.
Despite the superb stability characteristics of the C992 Holder tractor, the operator may cause
the tractor to tip over.
To prevent the tractor from tipping over:
lMaintain safe operating speed according to road/surface conditions.
lSlow down when
oturning
oworking on slopes
ocarrying heavy loads
odriving near ditches, ravines, excavations, embankments

Voltage Safety distance (m) Safety distance (ft.)
> 1 kV 1.0 3.5
< 1 kV > 110 kV 3.0 10.0
< 110 kV > 220 kV 4.0 13.5
< 220 kV > 1380 kV 5.0 17.0
Unknown voltage above 5.0 above 17.0
Table 2-1. Safety distance to overhead power lines
Risk of chemical burns from battery acid
Warning: Failure to comply with the following guidelines could result in serious or fatal
injuries.
