Hydraulic Hoses; Tires - Jacobsen F305 Operation And Maintenance Manual

8 MAINTENANCE AND LUBRICATION

8.17 HYDRAULIC HOSES __________________________________________________

!
WARNING
To prevent injury from the hot, high pressure oil, never use your hands to check for oil leaks.
Use 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,
please seek medical attention as soon as possible.
Always lower the cutting units to the ground, disengage all drives, engage Park 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. Prevent hose twist.
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.
IMPORTANT: If the hydraulic fluid becomes contaminated, damage to the hydraulic system can occur.
Before you disconnect any hydraulic component, clean the area around the fittings and the ends of the hoses to
stop the entry of contaminates 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 contaminates 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 twist. The 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.

8.18 TIRES _______________________________________________________________

Keep the tires correctly inflated to achieve optimum traction and tire life. Inspect the tread wear.
Check the tire pressure each day, while the tires are cool. Use an accurate low-pressure tire gauge.
Keep tires inflated at the correct pressure (see section 4.4)
!
CAUTION
DO NOT try to put a tire on a rim unless you have the correct training, tools and experience. Incorrect
mounting can cause an explosion which can cause injury.
