12 Volt Power and Hydraulics Set-up
If the unit has been crated and delivered via closed-van commercial freight, the tongue (if
equipped) may need to be installed prior to use. Prior to operating the implement for the first time,
it is important to check all fasteners – some may have loosened during shipment. Route cables
and hydraulic hoses along tongue and through hose guide. Tie-strap securely. Connect electrical
cables to battery. Be careful to attach black cable to negative/ground terminal. DO NOT
REVERSE POLARITY.
Figure 2
Insert hydraulic ends into quick-couplers, being careful to insert the end marked “P” into the tractor
extension coupler, and the end marked “T” into the tank or return line coupler; in this configuration,
tractor’s hydraulic lever will be secured in raised position. If sampler shoe operates in reverse,
simply reverse hydraulic hoses, or secure lever in lowered position. Note: Be certain whether
tractor or hydraulic power source utilizes open or closed-center hydraulics. Damage to
tractor could occur if not set properly. The poppet knob is set ‘up’ for open systems, and
‘down’ for closed-center systems – (see settings below.) Press down and turn knob to lock down—
press down, turn and release to allow it to move up to open position.
