Safe Operating Limits for Leveling
Your apparatus should be as level as possible prior to operation. It must be leveled within the limits shown in the
“Apparatus Leveling Safe Operating Limits” tables found in
Load Chart and Level Chart Information
of this manual
for the load chart values to be valid. In these conditions the apparatus angle indicators will be within the green range.
If you are unable to level your apparatus within the green range, you may set up within the yellow range, but only
with reduced load chart capacity. If either the Grade or Slope apparatus angle indicators are outside the green range
but still within the yellow range, then the device can be operated at 50% (half) capacity. This means that you must
cut each of the load values in the load chart in half. For example, if the load chart indicates an acceptable load with
500 lbs at the mid and 250 lbs on the base, then the half-capacity values when operating in the yellow range would
be 250 lbs at the mid and 125 lbs on the base. This 50% capacity condition is only safe if the apparatus is leveled
within the limits shown in
Load Chart and Level Chart Information
of this manual.
If you are unable to set up your apparatus with the apparatus angle indicators within either the green or yellow safe
limits, then the apparatus must be repositioned until it can be.
