HYDRAULIC SYSTEMS
HYDRAULIC CONNECTION:
Your Bin Trailer is supplied with Safeway or Pioneer tips. These will attach to most
tractor hydraulic systems. Contact your Northstar Attachments Dealer if other style of
tips are necessary. (Note: always clean tips of dirt and oil before installing.) The
hydraulic valve is set to operate with an open center hydraulic system. If your tractor has
a closed center system, you will need to replace plug @ 'A' as shown below. ) The closed
center plug is not supplied with your Bin Trailer.) Failure to change to a closed center
system will cause damage to your tractor hydraulic system.
HYDRAULIC OPERATION:
Your Bin Trailer is operated with a 2 function or 3 function valve. Handles 1 and 2 are for
tilting of Bin Trailer and lowering of the axle. Handle 3 is for operating the pick-up chain.
This function is supplied with a detent position that allows the operator to fully engage
the pick-up chain while tilting or lowering the Bin Trailer. Note: while operating your Bin
Trailer, you experience the inability to fully pick-up the fourth bin, you may need to adjust
the hydraulic pressure @ 'B'. (Remove the acorn nut and turn screw clockwise one turn
for every 300 PSI. Your tractor will only produce about 2200PSI and the valve is factory
set at 1500PSI.) If this does not correct the problem, your tractor may not have enough
hydraulics to operate the Bin Trailer properly.
