OWNERS MANUAL
FOR MEC 300E/400EWOBBLE
(SHOWN ON T-CART, NOT INCLUDED)
PLEASE READ AND FULLY UNDERSTAND THE INSTRUCTIONS PRIOR TO SETTING OR
TUNING THE MACHINE.
CAUTION: ANY MEC CLAY TARGET MACHINE MUST BE IN THE DISARMED STATE WITH THE
BATTERY DISCONNECTED PRIOR TO MAKING ANY ADJUSTMENTS, LOADING THE CLAY
TARGETS OR TRANSPORTATION OF MACHINE.
Step 1 –Securely set the machine in the trap house. See below for the correct way to install the
MEC machine into the trap house. IF NOT FASTENED SECURELY, SERIOUS INJURY AND/OR
DAMAGE TO MACHINE CAN OCCOUR!!!
DO NOT CONNECT THE POWER. Ensure that the machine is in the DISARMED/SAFE position.

Step 2 –In most cases, your machine has been supplied to you ready to fire. If so, please proceed
to Step 3. If your machine is supplied in a box without its carousel (shown below) fitted, you will need
to attach it to the machine. Simply slide the carousel weldment onto the top plate shaft. If no grease
is present, please add a little bit to the shaft. You may have to spin/rotate the carousel counter
clockwise for it to slide on. Next, place the gray plastic collar over the shaft and onto the flange
bearing in the carousel. Now place the ¾” washer and nut onto the threads and tighten. Do not over
tighten. You want a little bit of resistance there, but not too much. You shouldn’t be able to spin the
carousel with one finger.

Step 3 –Your machine was factory set to White Flyer clays. Some clays vary in size based on
manufacturer. You may need to check the height / clearance of the knife-edges by placing a clay in
the carousel. Rotate the carousel so that the clay starts to pass underneath the inner and outer knife
separator blades. The clay must pass freely under the knife separator blades without binding but with
the minimum of clearance. Adjust if necessary with 7/16” open ended wrench. You are looking for a
gap about the thickness of a business card, between the horizontal shoulder of the clay and the
underside of the knife edges. Photos below show adjustment with carousel fitted, but you can
remove the carousel to make adjustment easier if preferred.
** ALL MEC MACHINES ARE SET UP USING THE WHITE FLYER STANDARD
TARGETS. ADJUSTMENTS NEED TO BE MADE WHEN USING OTHER BRANDS
OR STYLES OF TARGETS**

Rotation Toggle Switch –Pushing the switch downward will turn the oscillation motor on. Note that
the oscillation motor will randomly start/stop when the machine is in operation. This prevents
shooters from being able to predict the direction of the next target. Pushing the toggle switch upward
allows you to nudge the oscillation motor which pivots the machine from one side to the other
enabling you to check the angle of the clays flight.
Elevation Toggle Switch - Pushing the switch downward will turn the elevation motor on. Note that
the elevation motor will randomly start/stop when the machine is in operation. This prevents shooters
from being able to predict the direction of the next target. Pushing the toggle switch upward allows
you to nudge the elevation motor which elevates the machine up and down enabling you to check the
clays flight.
Remote Disarm Socket –The machine is supplied with a remote disarm box assembly and 10ft. of
cable. This unit plugs into the remote disarm socket on the control box, allowing the remote disarm
box assembly to be placed by the opening of the trap house. The user can now disarm the machine
before entering the trap house.
Fire Button –The fire button allows you to test fire the machine from inside the trap house.
Disarm/Off/Arm –Pushing the switch downward to the arm state will arm the machine. Pushing the
switch upward will cause the machine to fire (if in armed state) and disarm when the switch is
released. Note –holding the disarm toggle will continually fire clay targets. Please use caution!
Breakers –The breaker on the left is for the oscillation motor. The breaker on the right is for the
cocking motor. If the breaker trips, it needs to be pushed back in to reset.
---------------------------------------------------------------------------------------------------------------------------------------
Step 4 –Check that the ARM/OFF/DISARM switch on the electrical box is in the OFF position.
Step 5 –Visually check, from the rear of the machine, that the motion of the Throwing Arm is not
restricted or blocked in any way.
CAUTION: ALWAYS OPERATE THE MACHINE FROM BEHIND, NEVER FROM
THE FRONT OR THE SIDES OF THE MACHINE. KEEP HANDS AND BODY PARTS
AWAY FROM THE MACHINE WHEN ARMING, RELEASING AND DISARMING.

Page 6 Version 2
Step 6 –Standing at arm’s length behind the machine and making sure that all body parts are clear
of the machine, push the ARM/OFF/DISARM toggle switch into the DISARM position and then
release it as soon as the throwing arm fires. The toggle switch is spring loaded and will return to the
off position as soon as the switch is released, stopping the machine from re-arming itself. If done
correctly the arm will be pointing away from the left side of the machine when viewed from behind.
Disconnect the power supply to ensure that the machine is not accidentally armed while
adjusting and loading the machine.
Step 7 –Place a couple of clays in each of the carousel columns, for the purpose of testing the clay
flight and trajectory.

ADJUSTING THE ELEVATION OF THE MACHINE
Step 8 –For ATA, set the angle of elevation, push the elevation toggle switch upwards to the nudge
position and release when the correct elevation is achieved. See the ATA guidelines for correct rules
regarding clay height and distance.
Step 9 –The machine comes pre-set from the factory, but it is possible to increase the Wobble
minimum angle of elevation in the following way. Loosen the ¾” jam nuts on the elevation crank
assembly and then either extend or retract the threaded rod. You will need to remove 3/8” allen bolt
from the elevation clamp block to allow you to adjust the height setting. NOTE: YOU WILL NEED TO
SUPPORT THE FRONT OF THE MACHINE WHEN MAKING THIS ADJUSTMENT AS THE
MACHINE WILL ROTATE DOWNWARD.
Step 10 –When shooting Wobble, push the elevation toggle switch down to the on position and the
machine will automatically move up and down.
Step 11 –The up and down angle of elevation is adjustable. Simply loosen the 3/8” allen bolt and
slide it out on the slot of the clamp block to increase the height of the clay flight. Retighten the bolt
securely and test fire. Sliding the bolt in on the slot will reduce the height of the clay flight.

ADJUSTING THE TILT/ANGLE OF THE MACHINE
Step 12 –Adjust the machines tilt by loosening the lever on the rear side (Photo #1) of the upright of
the machine as shown below. Tilt the machine to the desired angle by adjusting the turnbuckle.
(Photo #2) Adding tilt allows the machine to throw a flat target with no curl. Once the correct tilt has
been achieved
RETIGHTEN THE LEVER TO KEEP THE MACHINE FROM SHIFTING OVER TIME. NOTE: You
may need to use a ¾” wrench to make this adjustment on the turnbuckle.

CENTERING THE FIELD
Step 13 –Set the bolt in the center of the rotation gear box shaft as shown in Photo #1 below. To
center the field, fire a clay and see if the clay comes out of the center of the trap house and travels
straight away down the center of the field.
Step 14 –Next, adjust the turnbuckle if the clay is not traveling straight away down the center of the
field. Simply loosen the nuts on the turnbuckle and either push or pull the machine to get the trap to
fire the clay on center. RETIGHTEN THE NUTS ON THE TURNBUCKLE TO HOLD THE
CORRECT ADJUSTMENT!!!
Step 15 –Once centering the clay is achieved, remove the 3/8” allen bolt from the center of the shaft
(Photo #1), and place the jam nut under the clamp block as shown below in Photos #2, #3 and #4.
Step 16 –Tighten the bolt in the center of the clamp block slot. You can now test the angle that the
machine will throw the clay.
Step 17 –To open up the flight angle of the clay, loosen the 3/8” allen bolt and slide it out on the slot
of the clamp block. Retighten the bolt securely and test fire. Sliding the bolt in on the slot will reduce
the angle flight of the clay.
