Bleeding Hydraulics
To function properly, the hydraulics must be free of air. If
hydraulics have not been bled, they will operate with
jerky, uneven motions and could cause wings to drop
rapidly during folding or unfolding. If hydraulics were not
bled during initial implement setup or if you replace a
part in hydraulic system during the life of the drill,
complete the following procedures.
High Pressure Fluid Hazard:
Only trained personnel should work on system hydraulics!
Check all hydraulic lines and fittings before applying
pressure. Relieve pressure before disconnecting hydraulic
lines. Wear protective gloves and safety glasses or goggles
when working with hydraulic systems. Fluid escaping from a
very small hole can be almost invisible. Use paper or
cardboard, NOT BODY PARTS, to check for leaks. Escaping
fluid under pressure can have sufficient pressure to penetrate
the skin causing serious injury. If hydraulic fluid is injected
into the skin or eyes, seek immediate medical assistance from a
physician familiar with this type of injury. Within a few hours
gangrene can start to develop. DO NOT DELAY.
Negative Tongue Weight Hazard:
Be certain that drill is hitched securely to your tractor draw
bar and the safety chain is securely attached to tractor before
raising openers and unfolding drill. Raising openers on
unfolded, unhitched drill will cause drill tongue to rise
suddenly, which could cause serious injury or death.
Bleed only at:
JIC (Joint Industry Conference, 37
flare) or
NPT (National Pipe Thread, tapered thread) fittings.
Never bleed at:
ORB (O-Ring Boss) or
QD (Quick Disconnect coupler) fittings.
Check hydraulic fluid level in tractor reservoir and fill to
proper level. Add fluid to system as needed.
System capacity for entire drill is about
