WARNING
The HawkJaw is a closed center system which must
have a pressure compensated volume controlled
power unit. If the only available hydraulic power
unit is constant volume, then the optional hydrau-
lic converter kit (Part # 061-J80) is required. Run-
ning 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.
