OPERATION
5.3 PRE-OPERATION CHECKLIST
Efficient and safe operation of the Tile Plow requires that
each operator reads and understands the operating pro-
cedures and all related safety precautions outlined in this
section. A pre-operation checklist is provided for the opera-
tor. It is important for both personal safety and maintaining
the good mechanical condition of the equipment that this
checklist is followed.
Before operating the equipment and each time thereafter,
the following areas should be checked off:
1. Service the machine per the schedule outlined in the
maintenance checklist.
2. Use only a tractor of adequate power and specifications
to operate the machine.
3. Check that all guards are installed, secured and func-
tioning as intended. Do not operate with missing or
damaged shields.
4. Ensure that the equipment is properly attached to the
tractor and that mechanical retainers, such as quick
pins, are installed.
5. Visually inspect the hydraulic system for leakage, loose
fittings, and damaged hoses. Tighten fittings, replace
damaged components and wipe up leaked or excess
hydraulic fluid.
5.2 INITIAL ADJUSTMENTS
Before going to the field be sure to do the following:
• If using a Dual Grade system the relief valve
should be turned out all the way.
•
FOR PITCH-ONLY GRADING: Set the relief
valve. At the base of your lower cylinders there
is a pressure relief valve with a gauge. This is
used to determining how the plow goes through
the ground, the toe and heel angle. To set this
valve turn the knob on the valve in all the way,
raise the plow out of the ground and put lower
cylinders in the float position, the plow should
stay in the air. Then turn the knob out slowly
until the plow starts to creep down. Then turn it
back in about 1/4 turn and secure the jamb nut.
This is usually around 500lbs. of backpressure.
You will only see pressure on this gauge when
the plow is in the air, with the cylinders in “float”,
or when using the hydraulic pressure to lower the
plow. To check make a dry run and watch your
laser arm where your receiver is attached. This
arm is parallel to the bottom of the plow. When you
are plowing, the front of the laser arm should be a
½ to 1 inch higher than the back. If you see more
than that, increase backpressure by turning the
valve in. If the nose is down, decrease pressure.
• Calibrate your water level. With the boot and shank
placed on level ground adjust the indicator on your
water level to reflect where the water settles to.
This will ensure that you have the proper bench-
mark for further steps in this manual.
• Check the cylinders for proper travel direction.
When given a extend or up command from your
hydraulic toggle the cylinders must extend. This is
true for both Pitch and Elevation cylinders.
• Set your hydraulic flow rate for your 1 port and
3 port cylinders. Most tractors should be set to
60-70% on your dial to start. NOTE: For plow
operation with external hydraulic valve, tractor
hydraulic flow should be set to max or 100% so
there is adequate hydraulic flow for both pitch and
elevation cylinders working at the same time.
•
You will use a remaining free port for the power
feeder. This hydraulic flow should be set to around
30-40% on your dial. You can change the speed for
the feeder from either your hydraulic control panel
(this is preferred method to avoid generating ex-
cess heat in hydraulic oil) or minor adjustments at
the flow valve right before the motor on the power
feeder. Set the speed of the wheel a little faster
than what the tile is actually moving so it can spin
a little. Don’t forget to engage and disengage when
you stop and start or you run the risk of burning a
hole in the tile.
• If using the automatic hydraulics of your tractor
there will be an existing OEM machine control
cable installed on the tractor. Please refer to DAC
7000 machine controller manual to determine cable
location for your specific tractor. If you then remove
the DAC 7000 machine controller and leave the
wire attached to the tractor you may see an error
code on the tractor display.
•
If using GPS for corrections calibrate you survey
pass offset from the ground. This distance is the
measured difference from when the globe is in the
survey position on the plow and the when the plow
is level to the ground.
• Measure your rod height. This is the height from
the ground to the globe when the plow is set level
on the ground.
