SPECIAL TOOLS / CONSIDERATIONS: NONE
(Estimated time to complete: 8 hours)
When assembling / disassembling hydraulic components:
1. Thoroughly clean outside of hydraulic components before disconnecting hydraulic hoses or fittings
and flush hoses and fittings with air, solvent, or hydraulic fluid and cap disconnected hoses or open
ports to prevent contaminants from entering system.
2. Mark hydraulic hoses with locations of where they are attached. Markings make it easier to reconnect
hoses to proper locations.
3. Discard all hydraulic fluid drained from the system. Use only new approved hydraulic fluid to replenish
hydraulic reservoir. Hydraulic fluid is potentially dangerous to the environment. Obey all federal, state,
and local laws/regulations governing the disposal of environmentally hazardous materials when
disposing hydraulic fluid.
PROTECT THE ENVIRONMENT
Please dispose of packaging materials, used machine components
such as batteries and fluids in an environmentally safe way according
to local waste disposal regulations.
Always remember to recycle.
