INSTALLATION (PAGE 7)
SAS™ QUICK COUPLER
STEP 1 - PREPARATION:
• Establish a safe work area. A flat surface clean work area without trip hazards.
• Park wheel loader on firm level ground.
Lower exiting attachment (ie: bucket) to rest on ground.
Set parking brake and turn engine off.
• Follow wheel loader manufacturer’s instructions to depressurize hydraulic system.
• Do not work under a lifted object, loader arms or Quick Coupler. Avoid pinch & crush hazards.
• Remove existing pinned on attachment.
• Inspect pins & bushings in machine arms, replace as necessary.
STEP 2 - INSTALLATION:
• Apply grease to pins, bushings and pin holes on Quick Coupler.
• Align pin holes, insert pins and secure pins properly.
• Grease all pin zerk points.
STEP 3 - HYDRAULIC CONNECTION:
• Option #1: Electric pump kit from SAS Forks (diagram on next page)
• Option #2: Bucket roll back hydraulics with solenoid valve/switch.
• Option #3: Use 3rd spool auxiliary hydraulics on loader.
• Reference matching parts page within this manual to determine
maximum psi. (either 3,500; 5,000; 6,000). Have hydraulic pressure set below maximum.
• Determine hose length to avoid creating tension in all positions.
• Avoid excessive length that hoses would hang down to ground.
• Install high pressure hydraulic hoses. Recommend hose psi. to exceed cylinder requirements.
STEP 4 - TEST ROLL FORWARD AND ROLL BACK:
• During this test of motion, ensure smooth lifting & tilting of Quick Coupler. Watch for undesirable
contact between wheel loader lift arms and Quick Coupler. Also watch for hose pinch points.
• Begin testing by moving control levers slowly:
A. With Quick Coupler near ground level, fully roll back.
B. With Quick Coupler lifted high, fully rotate to dump position.
• Contact SAS FORKS™ if you experience interference issues to discuss stop options.
STEP 5 - TEST CYLINDER AND LOCKING PIN ENGAGEMENT:
• Engage hydraulics to actuate cylinder within Quick Coupler to extend Locking Pins.
• Visually verify Locking Pins are extended fulling into the exterior pin holes on the Quick Coupler.
• A few cycles of extend and retract maybe required to remove air from lines.
STEP 6 - CHECK & FILL HYDRAULIC FLUID:
• After installation test, check wheel loader hydraulic fluid level and fill as needed.

Installation of purchased attachment may void machine manufacturer warranty, if any.
►Installation of QUICK COUPLER on wheel loader requires interfacing with high
pressure hydraulic system. Installation should only be performed by qualified indi-
viduals, such as an experienced Heavy Equipment Service Technician. Failure to
follow these instructions and precautions in wheel loader manufacturer’s service
manual can result in serious damage to equipment and/or result in injury or death.
►Failure of hydraulic system or high pressure fluid leaks can result in serious injury
►Use caution while installing, testing & operating this unit. Be aware of and avoid:
-Pinch Points, -High Pressure hydraulic fluids or stored energy, -People in the area.
