"HYDRAULIC SYSTEM"
The hydraulic system supplied with a given hoist manufactured by TBEI-Rugby is made up of
components (pump, valves, reservoir, hoses, cylinder, etc.) that are designated to be compatible with
each other.
WARNING:
If you substitute hydraulic components, it is your responsibility to
BE SURE
they are
compatible with the other components supplied by TBEI-Rugby. Incompatible
hydraulic components may cause failure of the hoist that, in turn, could damage the
vehicle, damage other property, and cause human injury or death.
All TBEI-Rugby's liability and warranty for a given hoist will be voided, if it is determined by TBEI-
Rugby, that substituted hydraulic components were incompatible with those supplied by TBEI-Rugby.
Several hoist parameters are given in the following table, these parameters are given as a general
guide. To ensure component compatibility, consult TBEI-Rugby.
