Starting the Pump
While the planter is stationary, it may be necessary to
briefly operate the pump for any of several reasons:
• verify system installation or PTO operation.
• verify oil level with system fully charged.
• set initial meter pressurization.
Refer to Figure 13
1.
If the system is adjusted, leave the flow control
valve as-is.
If the system is not yet adjusted, close the flow
control valve to prevent fan motion. Turn the lock
disc
counter-clockwise to release the knob .
Turn the knob fully clockwise to close the valve.
2. Clear the hitch area of non-essential persons.
Check essential personnel for long hair, scarfs,
cords, frays, loose flaps and anything else that
might get entangled. Clear the area of dangling or
loose wires, straps, cord and other lines that might
become entangled and pull someone in.
3. It is not necessary to run the PTO at the full 540 or
1000 rpm. You may run it any lower speed that
provides sufficient meter pressurization (page 17).
Equipment Damage Risk:
Do not START the pump and fan suddenly at high PTO power.
Engage the PTO clutch slowly (if possible) and/or at low
engine rpm, and gradually increase PTO rpm. The hydraulic
fan can be damaged by sudden acceleration.
4. • Check that tractor is in Park or Neutral.
• Check parking brake set.
• Set the tractor PTO controls for
540 or 1000
a
rpm gearing (if multi-speed) and
clockwise rotation (if bidirectional).
• Start tractor engine and set throttle to idle.
• Engage the PTO.
• Bring the tractor engine and PTO up to intended
field rpms.
5. Check for hydraulic fluid leaks.
6. Verify fluid level in tank (page 14).
a. Operate above 540 rpm only with a 1000 rpm pump.

Entanglement and Crushing Hazard:
Use extreme caution in the hitch area when the PTO is
operating.
High Pressure Fluid Hazard:
Watch for signs of fluid leaks. Escaping fluid under pressure
can have sufficient pressure to penetrate the skin causing
serious injury. Use a piece of paper or cardboard, NOT BODY
PARTS, to check for leaks. Wear protective gloves and safety
glasses or goggles when working with hydraulic systems. If an
accident occurs, seek immediate medical attention from a
physician familiar with this type of injury.
