Section 2 - Paint Hog Systems
Most hydraulic motors are designed to rotate in one
direction. If a motor needs to be removed for any
reason, always make sure to mark the hoses and
ports so they will be installed in the correct position.
If the hoses are installed in the wrong ports, the
motor will rotate opposite of the designed rotation
which will permanently damage the motor.
Hydraulic Actuators
Hydraulic actuators are used to move the carriages
in or out while steering. Another hydraulic cylinder
raises and lowers the pointer arm.
All hydraulic circuits and actuators require special
procedures for bleeding air from the system after
servicing components or replacing hoses. Contact
Hog Technologies if you need assistance in bleeding
the air from the hydraulic system.
Hydraulic Hoses
The hydraulic system operates at pressures of up
to 3,000 psi (207 BAR). Therefore, it is critical that
the operator and maintenance personnel inspect
the hydraulic hoses, fittings and other components
frequently. A visual inspection of the entire hydrau-
lic system should be conducted each day before
operating the unit. Any hose or component that is
questionable or shows any sign of deterioration,
wear or leakage should be replaced immediately
and before operating the unit. A more thorough
inspection of the pumps and other components
should be conducted at each routine service inter-
val. Remember that the hydraulic system can be
severely damaged if it runs low on fluid.
Protect the hoses from contact with sharp objects
or kinks. Never operate the hydraulic system with
a damaged hose or a hose that is questionable.
Hydraulic Fluid Cooler
A heat exchanger on the side of the paint deck cools
hydraulic fluid during operation. It is equipped with
a fan powered by the 12 volt system that runs con-
stantly whenever the hydraulic system is activated.
The heat exchanger will loose efficiency if it be -
comes dirty. It is important to inspect cooling fins
at least once a week and clean them as necessary.
If the fins are not cleaned regularly, debris can
buildup to the point where the cooler will become
ineffective, causing the fluid and components to
overheat. This can result in severe damage to hy-
draulic system components.
