attachments with a hydraulic motor attached.
Important: If used with a hydraulic cylinder
or no attachment, the O
hydraulic-fluid flow to go over a relief valve which
can damage the hydraulic system. Use this position
only momentarily or with a motor attached.
Important: Check the hydraulic-fluid level after
installation of an attachment. Check the operation
of the attachment by cycling the attachment several
times to purge air from the system, then check
hydraulic-fluid level again. The attachment cylinder
will slightly affect the fluid level in the transaxle.
Operating the vehicle with a low hydraulic-fluid level
can damage the pump, remote hydraulics, power
steering, and the vehicle transaxle.
Connecting the Quick Couplers
Important: Clean dirt from quick couplers before
connecting. Dirty couplers can introduce contamination
into the hydraulic system
1. Pull back the locking ring on the coupler.
2. Insert the hose nipple into the coupler until it snaps
into position.
Note: When attaching remote equipment to the quick
couplers, determine which side requires pressure, then attach
that hose to quick coupler B, which will have pressure when
the control lever is pushed forward or locked in the O
position.
Disconnecting the Quick Couplers
Note: With both the vehicle and attachment turned off,
move the lift lever back and forth to remove the system
pressure and ease the disconnection of the quick couplers.
1. Pull back the locking ring on the coupler.
2. Pull the hose firmly from the coupler.
Important: Clean and install the dust plug and
dust covers to the quick coupler ends when not
in use.

– The pump is not operating.
•
There are hydraulic leaks.
– The fittings are loose.
– The fitting is missing the O-ring.
•
An attachment does not function.
– The quick couplers are not fully engaged.
