OPERATING PROCEDURES
Do not allow anyone to operate the YardJack Elevator who has not been properly trained
in its safe operation.
Prior to operation the following items must be checked and/or adjusted to obtain maximum
performance and avoid unnecessary wear and stoppages.
1. Check and clean engine air filter. See Engine Air Filter Maintenance instructions
Pages 14.
2. Check the engine oil level and add oil if low. See Maintenance Materials
Specifications Page 4 & 7.
3. Check engine fan and alternator belt. Tighten if loose. See Engine Maintenance
Manual for proper tension.
4. Check engine cooling air intake. Make sure it is clean and unobstructed. Clean with high
pressure air if dirty.
5. Check battery connections. Clean terminals if they are corroded.
6. Check the hydraulic oil level. Add oil if level is below bottom sight gauge (Bullet Type).
7. Check fuel level and fill if low.
8. Check tension of both conveyor belts on elevator. All conveyor belts should be tightened if loose.
Check the tension of Woodchuck conveyor belts and chain.
9. Start engine (warm up 3 - 4 minutes) at idle.
10. Turn on elevator and Woodchuck conveyor belts. Both horizontal and incline conveyor belts must
move freely. If they don’t move freely STOP engine and free belt or belts that do not
move freely.
11. After conveyor belts run smoothly at low speed check each belt. Make sure they track
evenly on both head shaft and tail shaft pulley. Adjust belts if they do not track evenly
Or if they are loose. They must carry a full load without slipping. See Conveyor Belt
Adjustments Instructions Page 17.
12. Run belts at fast speed 3 - 4 minutes then recheck tracking. Adjust as necessary.
Now you are ready to start operations.

DAILY OPERATION
The YardJack Elevator is designed to stockpile almonds or similar crops.
1. The Yard Jack Elevator engine should be started at idle. Warm up the engine at
Idle for 1 - 2 minutes.
2. To drive the YardJack Elevator from service or storage area the rear wheels used to drive
sideways must be raised to their full UP position.
A. PULL rear wheels height control joystick (15) and hold until both wheels are
In full up position. The wheels may come up one at a time.
3. PUSH the top of FRONT DIRECTION rocker switch (5) on the control panel. This
increases the flow of oil to the front drive wheel and allows faster forward travel.
4. Turn pivot seat until facing forward (toward single drive wheel).
5. Use joystick to turn front drive wheel until it faces forward. This should be done with the
wheel in the full raised position.
6. Lower the front drive wheel by pushing front wheel height control (18). Hold the joystick
forward until the wheel is in down position.
7. To travel forward PUSH the joystick forward. Turning while traveling can be
accomplished by:
A. Turning to left, PUSH joystick to the left.
B. Turning to right, PUSH joystick to the right.
C. To slow down or stop quickly, let the joystick come back to its resting position
and lower the drive over ramp.
The steering is non reactive. The front wheel stays where you put it. It does not return to
center.
8. With the YardJack located where the stockpile will be built:
A. Raise the front wheel to its full up position (18).
B. Lower the hopper flaps (17).
C. Raise or lower winkie to desired angle (16).
9

9. Drive a set of bottom dump trailers over the horizontal conveyor pan.
A. Center the first trailer door over the conveyor belt.
B. Raise the hopper flaps (17).
C. Turn on belts with engine at idle (2).
D. Increase engine speed to full throttle (3).
E. Smoothly open trailer door. The open door width should load the horizontal belt
and the horizontal belt speed control (19) adjusts the rate of flow to the incline
conveyor belt. The rate of flow on to the incline conveyor should be heavy but
allows the engine to run free (do not lug the engine).
F. A bottom dump trailer (semi doubles) should be unloaded in 2 - 4 minutes
provided it is relatively stick free.
G. After the first trailer is empty the YardJack’s engine speed is reduced to idle, the
belts are stopped, and the hopper flaps lowered and the second trailer door is
centered over the conveyor belt. Unload the second trailer as described above.
10. When the stockpile is built to the desired height the YardJack is moved laterally
to lengthen the stockpile.
A. The driver seat is turned with the driver facing the conveyor and looking in the
direction the YardJack will travel.
B. The rear wheels are lowered until they are in the full down position.
10

C. The front drive steering wheel is rotated 90 degrees to allow sideways travel.
D. The front drive wheel is lowered to its full down position.
E. the YardJack driver slowly pushes the joystick forward with his right hand and
simultaneously pushes forward the rear wheel drive control to move the YardJack
sideways.
F. The YardJack can be backed up by pulling the controls instead of pushing
them.
11. With the YardJack in a new stockpiling location:
G. The front and rear wheels are raised to their full up position.
H. The hopper flaps are lowered and you are ready for another set of doubles.
The joystick and the rear wheel drive control can operate the front and rear wheels at slightly
different speeds. This provides the ability to steer the YardJack along the stockpile. Severe
speed differences can cause air loss in tires or tire damage.
WOODCHUCK DESTICKER
The YardJack Elevator can be equipped with a Woodchuck desticker. When the
Woodchuck is used the Woodchuck/Winkie switch must be toward the Woodchuck and left
in the ON position. It will automatically start when the belt ON switch is pushed.
The drive over ramp belt must be slowed down (control 19) to allow time for the for the
Woodchuck to remove the sticks.
The Woodchuck can be turned OFF and raised above the crop when the crop is free of most
sticks.
11
10B

To raise the Woodchuck:
1. Turn the Key to The ON position.
2. Push the Woodchuck/ Winkie switch to the toward “Woodchuck” position.
3. Push and hold the Woodchuck/ Winkie joystick down of the rocker switch (arrow
pointing up 10) until the Woodchuck reaches its maximum height.
To lower the Woodchuck:
1. Turn the Key to The ON position
2. Push the Woodchuck ON – OFF switch to the ON position.
*Make sure the Woodchuck/ Winkie switch is set to Woodchuck.
3. Push the hold lever labeled Winkie until the Woodchuck rests on the incline
conveyor frame.
