Always use proper tools that are in good condition.
Make sure the procedure is understood before
performing any service work.
2.9 Hydraulic System Safety
1. Make sure that all the components in the hydraulic
system are kept clean and in good condition.
2. Make sure all components are tight, and that lines,
hoses and couplings are not damaged before
applying pressure to the system.
3.
Do not use a hand to check for
hydraulic oil leaks. Hydraulic fluid
escaping under pressure can
penetrate the skin causing serious
injury. Use a piece of cardboard.
4. Wear proper hand and eye
protection when searching for a
high pressure hydraulic leak.
5. If injured by a concentrated high-pressure
stream of hydraulic fluid, seek medical attention
immediately. Serious infection or toxic reaction
can develop from hydraulic fluid piercing the skin
surface.
6. Do not attempt any makeshift repairs to the
hydraulic lines, fittings or hoses by using tape,
clamps or cements. Doing so can cause sudden
failure and create a hazardous and unsafe
condition.
7. Relieve pressure on the hydraulic system before
working it. The hydraulic system operates under
extremely high pressure.
8. Replace any hydraulic hose immediately that
shows signs of swelling, wear, leaks or damage
before it bursts.
9. Do not bend or strike high-pressure lines, tubes
or hoses, or reinstall them in a bent or damaged
condition.
10. Check to make sure hydraulic hoses are not worn
or damaged, and are routed to avoid chafing.
11. Never adjust a pressure relief valve or other
pressure-limiting device to a higher pressure than
specified.
12.
Never disable a hydraulic system interlock device.
They prevent the engine from starting or the
hydraulic system from engaging if the operator
restraint is not fastened or properly positioned.
