the system, then check hydraulic-fluid level
again. The attachment cylinder slightly affects
the fluid level in the transaxle. Operating the
machine with a low hydraulic-fluid level can
damage the pump, remote hydraulics, power
steering, and the machine 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 you push the control lever
forward or lock it in the O
Disconnecting the Quick Couplers
Note:
With both the machine 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.
