1. Assemble the existing hoses from the boom fold cylin-
ders as well as the elevator and attach them to the hy-
draulic solenoid, you will need to detach them from the
existing elbows in each hydraulic hose.
2. Assemble the hydraulic solenoid wiring harness (5) to
the solenoids according to the wire colors shown.
Route your wiring harness from the hitch to the sole-
noid valve in a manner that prevents kinking, droop-
ing, or damage to the harness. If you have a TS
sprayer, route the harness next to the existing sprayer
harness. Loop the harness around the left side of the
elevator similar to the routing of the hydraulic hoses.
Make sure the wiring harness has enough slack
around the elevator when the elevator is raises.
3. Hook up the power terminals on your control box with
the red terminal on the (+) positive battery terminal
and the black wire on the (-) negative battery terminal.
4. Make sure your hydraulic cylinders are primed with
hydraulic fluid, and the cylinders are cycled at least
two strokes before attempting to fold the boom.
!
WARNING
Failure to prime the cylinders with hydraulic oil before folding
a boom that has just been assembled can cause serious injury
or death to bystanders and serious damage to the boom.
5. Use the control box to actuate the hydraulic solenoid
valves and see if the boom is operating correctly. To
use, engage the hydraulic lever on the remote that has
the hydraulic hoses attached that feed the hydraulic
solenoid valves, and then operate the switches.
6. After checking the function of the solenoid valves,
place the cover (4) on the solenoid mount (1) with the
bolts and washers provided.
Bypass Valve Assembly Instructions
The bypass valve is used when you have an open-center
hydraulic system or a flow-compensated hydraulic system
on your tractor. The valve allows flow back into the hydrau-
lic reservoir on the tractor and keeps the hydraulics from
going through the relief valve on the tractor. To assemble
the bypass valve on the existing solenoid valve, follow the
following instructions.
