Checking Hydraulic Hose
To avoid personal injury:
A
Be sure to stop the engine, remove the key, and
relieve pressure before checking and replacing
the hydraulic hose.
A
Allow the transmission case to cool down
sufficiently; oil can be hot and may cause
burns.
Check to see if hydraulic hoses are properly fixed every
200 hours of operation.
1. Check to see that all lines and hose clamps are tight
and not damaged.
2. If hoses and clamps are found worn or damaged,
replace or repair them at once.
3. Escaping hydraulic fluid under pressure has sufficient
force to penetrate the skin causing serious personal
injury. Before disconnecting lines, be sure to relieve all
pressure. Before applying pressure to the system,
make sure all connections are tight and that lines,
pipes, and hoses are not damaged.
4. Fluid escaping from pinholes may be invisible. Use a
piece of cardboard or wood to search for suspected
leaks: do not use hands. Use safety goggles or other
eye protection.
If injured by escaping fluid, see a medical doctor at
once. Serious infection or reaction will result if proper
medical treatment is not administered immediately.
This fluid can produce gangrene or severe allergic
reaction.
