WARNING
The HawkJaw is a closed center system which
must have a pressure compensated volume con-
trolled power unit. If the only available hydraulic
power unit is constant volume, then the optional
hydraulic converter kit (Part # 061-J80) is re-
quired. Running the HawkJaw with a constant
volume hydraulic power unit may result in bodily
injury and will cause damage to the HawkJaw
and to the hydraulic power unit.
WARNING
The HawkJaw must receive clean hydraulic fluid.
Running the HawkJaw without a Hawk approved
filter (Part # 061-H25) and installed filter element
(Part # 061-H25A) voids the warranty and severely
shortens component life.
