MAINTENANCE
Cylinder Rod Maintenance
It is important to visually inspect the hydraulic cylinder rods daily before use. It is highly recommended that
while the machine is stored or getting very little use that a protectant is applied to the hydraulic cylinder rods to
prevent degradation. If the machine receives more frequent use, be sure to fully cycle each cylinder function so
that the cylinder rod is coated by the systems hydraulic fluid. Depending on your operating environment it may
be necessary, under normal operating conditions, to apply a protective lubricant to the cylinder rods for
protection against rust and pitting. Hydraulic fluid may provide a suitable amount of protection, but remember
any protectant can attract dust and debris so attention must be given to the cylinder rods daily. Also remember
that any other protectant must be compatible with hydraulic fluid. Bush Hog is not responsible for rust or pitting
of the cylinder rod due to weather exposure or impacts from normal operation or mounting. If hydraulic
cylinders and or the cylinder rods are damaged as a result of the rods rusting or pitting, the hydraulic cylinders
and rods will not be covered under warranty by Bush Hog.
CONTROL VALVE
Non Return Valve
The non return valve prevents the feedback of oil from the service parts. It is unlikely to need attention but if
removed for cleaning, a new “O” ring should be used when refitted.
