WARNING
DO NOT disconnect or remove any hydraulic system line or fitting unless engine is shut
down and hydraulic system pressure has been relieved.
Escaping hydraulic fluid under pressure can penetrate the skin, causing injury to
personnel.
When disposing of hydraulic fluid, consult your unit/local hazardous waste disposal center
or safety office for local regulatory guidance.
Lubricating/hydraulic oils can be very slippery. Immediately wipe up any spills.
Failure to follow these warnings may result in injury to personnel.
NOTE
Tag and identify all hose flanges for ease of installation and to protect and identify for
assembly. Cap all hose flanges to prevent contamination and leaks.
