8 MAINTENANCE AND LUBRICATION
8.7 HYDRAULIC HOSES ___________________________________________________
Always lower the cutting units to the ground, disengage all drives, engage parking brake, stop the engine and
remove the key before you inspect or disconnect hydraulic lines or hoses.
Check visible hoses and tubes each day. Look for wet hoses or oil marks. Replace worn or damaged hoses and
tubes before you operate the mower.
The replacement tube or hoses must follow the same path as the original hose. Do not move the clamps,
brackets and cable-ties to a new location.
Completely inspect all tubes, hoses and connections in accordance with the maintenance chart.
Before you disconnect any hydraulic component, clean the area around the fittings and the ends of the hoses to
stop the entry of dirt into the system.
Before you disconnect any hydraulic component, tag or mark the location of each hose then clean the area
around the fittings.
To stop the entry of dirt into the system when you disconnect the component, be prepared to assemble plugs or
caps to the ends of hoses and open ports. Clean any hydraulic fluid that spills.
Make sure “O” rings are clean and hose fittings are correctly installed before you tighten.
Prevent the hose from twisting. Twisted hoses can cause the hose connections to loosen as the hose moves
while you operate the mower and can cause oil leaks.
The hydraulic hoses that are twisted or have sharp bends can decrease the oil flow and cause damage to the
hoses. The decreased oil flow can cause system problems and increase the temperature of the hydraulic fluid.
WARNING
To prevent injury from the hot, high pressure oil, never use your hands to check for oil leaks. Use the
paper or cardboard to find leaks.
The hydraulic fluid pressure can have enough force to enter your skin. If hydraulic fluid has entered
your skin, a doctor must remove the hydraulic fluid surgically within a few hours or gangrene can
occur.
NOTICE
If the hydraulic fluid becomes dirty, damage to the hydraulic system can occur.
WARNING
Only trained personnel must service the hydraulic system.
CAUTION
Hydraulic oil can damage your skin. Use gloves when you use hydraulic oil. If hydraulic oil touches
your skin, clean the area immediately.
Discard used hydraulic oil in accordance with local regulations.
