HYDRAULIC SYSTEM SERVICE PRECAUTIONS
Relieve all trapped pressure before performing any service to the
hydraulic system. Pressure can be maintained in the hydraulic circuits
long after the power source and pump have been shut down.
Relieve all pressure before disconnecting hoses or tubes.
Tighten all connections before applying pressure.
It is important that each person who comes in contact with the machine
be alert to any faults.
Follow these basic precautions:

Never adjust a pressure relief valve or other pressure-limiting
device to a higher pressure than specified.

Check to make sure hydraulic hoses are not worn or damaged,
and are routed to avoid chafing.

When connecting mower to tractor ensure hydraulic hoses have
sufficient slack for negotiating turns and uneven terrain.

Immediately replace any hydraulic hose that shows signs of
swelling, wear, leaks or damage so it does not burst.

Do not use your hand to check for hydraulic oil leaks. Use a
piece of cardboard instead. Hydraulic fluid escaping under
pressure can penetrate the skin causing serious injury. If skin
penetration occurs, seek medical attention immediately. Relieve
all pressure before disconnecting hoses.

Do not bend or strike high-pressure lines, tubes or hoses, or
reinstall them in a bent or damaged condition.
HYDRAULIC OIL HANDLING PRECAUTIONS
Oils can irritate and damage the eyes, throat, and sensitive skin. Avoid
contact.
Petroleum based oils are hazardous to the environment. Take special
care not to spill or discharge these fluids. Use approved containers and
methods to handle and dispose of them.
Use authorized disposal and recycling methods per jurisdictional
requirements.
Risk of personal injury! Wear safety glasses
and use protective gloves.
