INSPECTING HYDRAULIC HOSES AND FITTINGS
Do not attempt to inspect the hydraulic hoses or
fittings with the truck engine running, the truck
hydraulic power engaged, the spinner motors
operating, or the conveyor drive motor operating.
Check the condition of the hydraulic hoses. The hoses
have a protective covering to control leakage in the
event of a hose breaking. Leaks and worn hoses
should be fixed or replaced before the machine is put
into service. The hydraulic system has pipe thread
fittings on some of the components. If disassembled,
reseal the pipe thread fitting with Teflon
®
tape or pipe
dope.
TO AVOID SERIOUS INJURY,
Never Service Any Part Of The
Hydraulic System With The Engine
and Pump Operating. High Hydraulic
Pressure And High Oil Temperatures
Can Cause Serious Injury Or Death.
Do Not Use Your Fingers Or Hands To Check
For Hydraulic Leaks. High Pressure Leaks Can
Puncture The Skin And Force Oil Into The Body.
This Can Cause Severe Injury Or Death.
Be Aware of High Hydraulic Oil Temperatures.
Serious Burns and Injuries Are Possible.
HYDRAULIC FLUID
The machine was factory tested using “vegetable”
based biodegradable hydraulic fluid. Approximately
1.9 liters (1/2 gallon) of vegetable based fluid can
remain in the WideSpin 1540 TEC hydraulic system
after testing. This fluid will mix well with mineral based
fluids. However, when vegetable fluid is mixed with
mineral fluids, it can have a minor effect on the overall
fluid properties. If this fluid is not compatible with the
fluid in the truck, or if concerns of contamination to the
trucks system are present, flush the hydraulic system
in the WideSpin 1540 TEC before attaching the hoses
to the truck. See section “Draining Hydraulic System”.
This procedure is meant for qualified service personnel
only.
TO AVOID CONTAMINATION OR DAMAGE TO THE
TRUCKS HYDRAULIC SYSTEM,
Properly Identify the Type of Hydraulic Fluid
Being Used Before Refilling the Trucks Reservoir.
The trucks hydraulic system provides all of the hydraulic
power and fluid to operate the WideSpin 1540 TEC. The
WideSpin 1540 TEC does not have its own separate
hydraulic fluid reservoir. Check the trucks system for
the type of fluid to use (vegetable or mineral) before
replenishing the trucks hydraulic system.
Refer to the operators manual for the truck to
determine the proper type of hydraulic fluid to use
and for the maximum operating temperature range for
the type of fluids being used.
DRAINING HYDRAULIC SYSTEM
The hydraulic system is self-bleeding and does not
normally store or retain any pressure when the trucks
pump is not in operation. However, in the event of
failure of certain components, hydraulic pressure
can be trapped in the system. Pressure can also be
present in the lines if a hose was removed from the
truck while the trucks pump is in operation. Before
servicing any component, check for any remaining
hydraulic pressure.
● Allow time for the hydraulic oil in the system to cool.
● Disconnect the quick release fittings from the spinner
assembly.
●
Do Not Start Engine To Use The Hydraulic Pump To
Pump The Hydraulic Oil Out Of The System.
TO AVOID SERIOUS INJURY,
Be Aware of the Possibility of Trapped High
Pressure in the Hydraulic System.
DO NOT USE HANDS TO CHECK FOR LEAKS!!
WEAR SAFETY GLASSES!!
To drain the system, remove the quick release fitting
from the end of the “pressure out” hydraulic hose that
connects to the truck. Be prepared to safely catch and
contain approximately 1.9 liters (1/2 gallon) of hydraulic
oil.
Do Not Use The Trucks Hydraulic Pump To Pump
The Hydraulic Oil Out Of The System.
Some hydraulic oil will always remain in the system
and in the components. Always be prepared to properly
catch and contain any remaining hydraulic oil when
servicing the hydraulic system components.
PRESSURE IN AND OUT HYDRAULIC HOSES
The quick disconnect on the pressure out hose must
be properly and completely connected to the truck. If
the quick disconnect is not properly connected to the
truck, excessive pressure can build up in the WideSpin
1540 TEC resulting in a safety hazard and causing
serious damage to the top dressers hydraulic system.
