Note:
When you connect the attachment male coupler
first, you will relieve any pressure build up in the
attachment.
Hydraulic fluid escaping under pressure can
penetrate skin and cause injury. Fluid injected
into the skin must be surgically removed within a
few hours by a doctor familiar with this form of
injury or gangrene may result.
•
Keep your body and hands away from pin hole
leaks or nozzles that eject high pressure
hydraulic fluid.
•
Use cardboard or paper to find hydraulic leaks,
never use your hands.
Warning
Hydraulic couplers, hydraulic lines/valves, and
hydraulic fluid may be hot. If you contact hot
components you may be burned.
•
Wear gloves when operating the hydraulic
couplers.
•
Allow the traction unit to cool before touching
hydraulic components.
•
Do not touch hydraulic fluid spills.
Caution

If the attachment uses hydraulics, move the auxiliary
hydraulics lever forward, back and forth, and back to
neutral to relieve pressure at the hydraulic couplers.
