the hydraulic system. Use this position only
momentarily or with a motor attached.
Important: Check hydraulic oil level after
installation of an attachment. Check the
operation of the attachment by cycling the
attachment several times to purge air from
system, then recheck hydraulic oil level. The
attachment cylinder will slightly affect transaxle
oil level. Operation of vehicle with low oil level
can damage the pump, remote hydraulics,
power steering, and the vehicle transaxle.
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 the engine, apply the parking
brake, lower the attachment, and place the
remote hydraulic valve in the float detent
position to relieve hydraulic pressure before
connecting or disconnecting quick couplers.
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 On 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.
Troubleshooting the Hydraulic Control
• Difficulty in connecting or disconnecting quick
couplers.
Pressure not relieved (Quick coupler under
pressure).
• Power steering hard
– Hydraulic oil level low
– Hydraulic oil hot
– Pump not operating
– Belt loose
• Hydraulic leaks
– Fittings loose
– Fitting missing O-ring
• Attachment does not function
– Quick couplers not fully engaged
– Quick couplers are interchanged
• Squealing noise
– Remote valve left in the On detent position
causing hydraulic oil to flow over the relief valve
– Belt loose
• The engine will not start.
