Important
Check hydraulic oil level after installation
of attachment. Check operation of attachment by cycling
attachment several times to purge air from system, then
recheck hydraulic oil level. Attachment cylinder will
slightly affect transaxle oil level. Operation of vehicle with
low oil level can damage pump, remote hydraulics, power
steering and vehicle transaxle.
Caution
Hydraulic fluid escaping under pressure can have
sufficient force to penetrate skin and do serious
damage. Care must be used when connecting or
disconnecting hydraulic quick couplers. Stop
engine, apply parking brake, lower attachment
and place remote hydraulic valve in float detent
position to relieve hydraulic pressure before
connecting or disconnecting quick couplers.
Quick Coupler Operation
Connection
Important
Clean dirt from quick couplers before
connecting. Dirty couplers can introduce contamination to
hydraulic system.
Insert hose nipple into coupler until it snaps into position.
Note: When attaching remote hydraulic cylinders to the
quick couplers, determine which side of the remote
cylinder requires pressure, then attach that hose to quick
coupler "B". Only connect double acting cylinders (two
hoses).
Disconnection
Pull hose firmly from coupler
Important
Clean and install dust plug and dust covers
to quick coupler ends when not in use.

• Difficulty in connecting or disconnecting quick
couplers.

pressure).
• Engine running.
• Remote hydraulic valve not placed in float.
• Power steering hard.
• Remote valve not in neutral or float position.

• Hydraulic oil level low.
• Hydraulic oil hot.
• Hydraulic leaks.
• Fittings loose.
• Fitting missing o–ring.
• Attachment does not function.
• Quick couplers not fully engaged.
• Quick couplers are interchanged.
• Squealing noise.
