OPERATING INSTRUCTIONS
BEFORE YOU START DIGGING (CONTINUED)
Once the unit is positioned, lower the stabilizers to the ground. The tires should still be
supporting most of the vehicle weight with the stabilizers relieving only part of the weight, and mainly
acting to give the unit a wider base for increased stability and to keep the unit from moving or bouncing
with backhoe use. The front end loader should also be lowered if the unit is so equipped. The vehicle
should at no time be supported by the stabilizers and loader with any of it's wheels off the ground. Severe
damage to the vehicle could result. When operating the unit on a delicate surface (such as concrete, or
stone work) or on sandy, loose, or soft ground place plywood under the stabilizers to help distribute the
load over a wider area.
