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
Pull back locking ring on coupler.
Insert hose nipple into coupler until it snaps into
position.
Disconnection
Note: With both the vehicles turned off, move the lift
lever back and forth to remove the system pressure and
ease the disconnection of the quick couplers.
Pull back locking ring on coupler.
Pull hose firmly from coupler.
Important: Clean and install dust plug and dust
covers to quick coupler ends when not in use.
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.
