This manual provides guidelines and instructions for correctly operat-
ing and maintaining your Rugby Manufacturing Co. product. Any and all
people that own and operate a Rugby Manufacturing dump trailer are
recommended to read and fully understand each section in this manual.
Throughout this manual, the three following types of labels will be used:
Danger, Warning, and Caution. For the safety of the operator, it is impera-
tive that all labels are obeyed.
DANGER
Indicates imminent danger. Failure to follow this instruc-
tion will result in death or serious injury.
WARNING
Indicates a possibly impending danger. Failure to follow
this instruction can result in death or serious injury.
CAUTION
Indicates a hazardous situation or unsafe practice which,
if not avoided, could result in injury or component
damage.
In all cases, Rugby products are sold with the understanding that the pur-
chaser agrees to thoroughly train all operating and maintenance person-
nel in the correct and safe installation and operation of hoist equipment
and to provide adequate supervision of personnel at all times.
Read the following in its entirety before connecting, operating or repair-
ing equipment. Purchasers and operators also should be familiar with
the current version of any applicable OSHA regulations, standards and
guidelines.

The hydraulic system supplied with an SR-Series hoist manufactured by
Rugby Manufacturing Co. is made up of components (pump, valves, res-
ervoir, hoses, cylinder, etc.) designed to be compatible with each other.
Several different types of pump and hydraulic components are available
to power the SR-Series hoists. Refer to the pump and hydraulic compo-
nent Installation and Operation Manual for more information.
DANGER
It is the installer’s responsibility to ensure any substitut-
ed components are compatible with Rugby Manufactur-
ing Co. components. Incompatible hydraulic components
may cause failure of the hoist, which in turn, could
damage the vehicle, damage other property, and cause
death or injury.
If hydraulic components are substituted, it is the installer’s responsibility
to be sure they are compatible with the components supplied by Rugby
Manufacturing Co. Incompatible hydraulic components may cause failure
of the hoist which in turn could damage the truck, damage other prop-
erty, and cause human injury or death. Rugby Manufacturing Company’s
liability and warranty for a given hoist will be voided if it is determined
by Rugby Manufacturing Co. that substituted hydraulic components were
used that were incompatible with those supplied by Rugby Manufacturing
Co.

DANGER
Avoid bouncing or jerking of the hoist. This may result in
component failure, injury or death.
DANGER
Never raise or drive a raised body against another object.
This may result in property damage, injury or death.
DANGER
Never connect the hoist to a hydraulic system with more
pressure (psi) or flow (gpm) than is recommended. This
may result in component failure, injury or death.
DANGER
Never operate the hoist until bystanders are free & clear
of the hoist and body. This may result in injury or death.
DANGER
Never exceed the gross vehicle weight (GVW) or gross
axle weight (GAW) rating of your vehicle. This may result
in component damage, injury or death.
CAUTION
Unlatch tailgate prior to elevating a loaded dump body as
excessive forces on the rear of the dump body may result
in component failure.
