MAINTENANCE
This section refers to components commonly found in a hydraulic system.
General
1. Keep the components clean at all times. Many hydraulic service
problems are caused by dirt and/or metallic particles in the hydraulic
system. To avoid these problems, the use of proper maintenance
including rust prevention and cleanliness will help extend the life of
your hydraulic system.
2. Use only an approved clean hydraulic fluid and change fluid as
recommended by the manufacturer. Change fluids more often if unit is
used under extreme conditions.
3. Change or clean the filter in the system periodically if one is used.
Hydraulic Hoses
1. Hydraulic hoses should be left in carton until needed.
2. Store hoses at a temperature between 50º to 75ºF [10º to 24ºC ] and
at a humidity between 20 and 70 percent.
3. Never store hoses in a hot, damp room, in direct sunlight or near heat
sources.
4. Do not stack hoses. The weight of the pile will tend to flatten the hose
on the bottom. Hanging in a rack is preferred.
5. Do not carry or drag hydraulic assemblies by pulling or pushing on
couplings or hoses.
Fittings and Couplers
1. All coupler threads, either male or female, must be kept clean and
lubricated regularly. Cover couplers with dust caps when not
connected to system. Do not remove covers or plugs until component
is ready to be used.
2. Keep dust caps on couplers when not in use. Make certain that all
unused couplers are sealed with dust caps/thread protectors.
3. Be sure all hose connections are free of grit and grime.
