STEP 2: Set the Grapple down in front of the Postmaster, aligning the square tubes of the
Grapple with the square tubes of the Postmaster (one on either side of the chain
guard and drive assembly).
STEP 3: Remove the hitch pins from the Grapple mounting tubes.
STEP 4: Slide the square tubes of the Grapple into the tubes of the Postmaster. Align the
mounting holes, and insert the provided hitch pins and hair pins.
STEP 5: Route the hydraulic hoses for the Grapple through the quick attach plate hose
holder, and connect the couplers to the corresponding couplers located directly
below the flow control.
STEP 6: The Grapple hydraulic system has been shipped dry and will require the auxiliary
hydraulics be activated slowly to fill the hoses and cylinder. (The Grapple may act
erratic until all the air is out of the hydraulic system.)
STEP 7: With the vehicle running at slow idle, turn the auxiliary hydraulics to the forward
position for a few seconds at a time until the Grapple arms raise. (Be cautious
when the Grapple is raised and the jaws are completely open, as the hammer will
rise.)
STEP 8: Reverse the auxiliary hydraulics until the jaws close.
STEP 9: Repeat STEPS 7 and 8 until Grapple operation is smooth.
STEP 10: Once you have accomplished smooth operation and the Grapple jaws are closed,
return the auxiliary hydraulics to the forward position until the hammer starts to
raise. This will raise and open the Grapple jaws.
