WARNING!
Avoid Injury Or Death.
Diesel fuel or hydraulic fluid under pressure can penetrate skin or
eyes, causing serious injury or death. Fluid leaks under pressure may
not be visible. Use a piece of cardboard or wood to find leaks. Do not
use your bare hand. Wear safety goggles. If fluid enters skin or eyes,
get immediate medical attention from a physician familiar with this
injury.
To Connect: Remove dirt or
debris from the surface of both
the male and female couplers,
and from the outside diameter
of the male coupler. Visually
check the couplers (Item 1 and
2) for corroding, cracking, dam-
age, or excessive wear. If any of
these conditions exist, the cou-
pler(s) must be replaced.
Install the male coupler into the
female coupler. Full connection is made when the ball release
sleeve slides forward on the female coupler.
To Disconnect: Relieve hydraulic pressure. Hold the male cou-
pler. Retract the sleeve on the female coupler until the couplers
disconnect.
Relieve Hydraulic Pressure (Utility Vehicle And
Attachment)
Utility Vehicle
• Lower the attachment
arm fully and put the
attachment flat on the
ground. Stop the engine.
Place the gear selector
lever in Park. (The util-
ity vehicle key needs to
be in the ON position.)
• Move the switch (Item
1) to the left and right
several times to relieve
pressure at the couplers.
Attachment
• Follow procedure above to release pressure in the utility
vehicle.
• Connect male coupler from attachment to female coupler of
the utility vehicle then repeat procedure above. This will
release pressure in the attachment.
• Connect the female coupler from the attachment to the male
coupler of the utility vehicle.
Hydraulic pressure in the auxiliary hydraulic system can make
it difficult to engage quick couplers to an attachment.
