SAFETY RULES
NO MORE THAN 6 V-DOSC ENCLOSURES SHOULD BE STACKED ON ONE BUMP2.
ALWAYS ATTACH ROTATING LEGS AND ANGLE STRAPS BETWEEN ENCLOSURES.
Test the strength of the supporting floor and, if necessary, use plywood sheets or steel plates under
individual screwjack feet in order to help distribute the load.
The maximum downward or upward tilt angle of the bumper is 12 degrees.
When stacking on scaffold platforms, install 2 rear screwjacks only (for downwards tilt) and ratchet
strap the BUMP2 to the platform for improved stability (see Figure 91)
