Shaker operation
If you have never operated a shaker before or a
new COE S7 model shaker follow these easy
steps to help familiarize yourself with the machine,
its operation and characteristics. It is important to
make sure you know and have experience with the
controls and operation of them. If you have not re-
viewed the “Operators Control Area” on the previ-
ous page, take the time to do that now. With the
machine off, sit in the seat in a comfortable posi-
tion. Look over the various controls and there label-
ing. Also take time to view all safety warning decals
and there placements. Now that you have done the
above its time to try the controls with the machine
running.
BEFORE STARTING make sure all controls are in
neutral or off. To start the machine simply turn the
key as you would in a car. After starting raise the
Shaker head from its resting position on the
ground. Now you can begin to activate each func-
tion individually. Make sure to do this at an Idle with
the machine clear of people and objects. When
operating the functions notice the speed and
changes of what is going on. Take special notice of
the moving parts. NEVER allow people or objects
in these crush hazard areas serious injury or death
could occur. Continue to repeat these functions
until you become familiar with the use and feel of
them.
Now you are ready to try on real trees. Set engine
RPMs to 1,700 to 1,800. ALL functions of shaker
were designed to operate optimal at this RPM set-
ting. When entering the row make sure the SHAK-
ER HEAD is fully retracted and the HEAD is low to
clear all branches and limbs when entering tree
row. Try to enter the tree row as square with the
row you are going to shake as possible keeping
about 12” to 18” between the HEAD and tree trunk.
Pull up to the tree you are going to shake and plac-
ing the clamp jaws as close to the center of the
trunk as possible. Now extend the shaker head out
(always make sure the clamp is fully opened)
toward the tree until the trunk is in the center of the
shaker pads. It is very important to make sure
clamp is centered on trunk or clamp may “PINCH
OFF” bark. Now begin the clamping. When the set
clamp pressure is reached the shaking will auto-
matically begin.
You can use the throttle to increase or decrease
the speed of the shake or other hydraulic functions.
When you have finished shaking simply release the
button to stop the shaking action. ONLY when shak-
ing has fully stopped may you un clamp from the
tree trunk. “ALWAYS WAIT FOR SHAKING TO
FULLY STOP OR DAMAGE TO TREE AND SHAK-
ER HEAD WILL OCCUR.” When unclamping open
the shaker head clamp fully, this is necessary to re-
set the shake sequence.
Now retract the shaker head. After fully retracting
depress the propulsion pedal to the forward position
to move to the next tree. Continue to repeat each
sequence of event. Take it slow at first. As you be-
come more used to the shaker your speed and ac-
curacy will increase.
The COE side mount shaker is very rugged but not
indestructible. It is important to follow these guide-
lines to prevent unnecessary damage and costly
repairs.
LINE UP TREE TRUNK TO STATIONARY SIDE
OF SHAKER HEAD (NOT CLAMP ARM)
NEVER UNCLAMP UNTIL SHAKE HAS FULLY
STOPPED. CLAMP CYLINDER FAILURES WILL
OCCUR IF OPENED WHILE STILL SHAKING.
FULLY UNCLAMP BEFORE RETRACTING
SHAKER HEAD OR MOVING TO NEXT TREE.
FULLY RETRACT SHAKER HEAD BEFORE
MOVING TO NEXT TREE.
KEEP 12” TO 18” BETWEEN SHAKER HEAD
AND TREE TRUNK.
DO NOT RUN INTO OBJECTS WITH SHAKER
HEAD OR CARRIAGE DAMGE WILL OCCUR.
SET THE PROPER CLAMP PRESSURE FOR
THE SIZE TREES BEING SHAKEN.
WARM SHAKER UP FOR 10-15 MINUTES
PRIOR TO SHAKING.
PERFORM ROUTINE MAINTENANCE AND
REPAIRS AS REQUIRED.
MAKE SURE ALL FLUID LEVELS ARE AT
REQUIRED LEVELS PRIOR TO OPERATION.
ALWAYS USE SILICONE SOLUTION IN WATER
SYSTEM OR BARK DAMAGE WILL OCCUR.

BRAKES
The braking system has two settings. PARKING and ACTIVE. SET the brake to AC-
TIVE in hilly conditions to AUTOMATICALLY DECELERATE and HOLD the shaker on
hills. USE the PARKING setting when you want to set brake when loading shaker on a
trailer. This brake is a DUAL style with a SPRING applied PRESSURE released FAIL-
SAFE and a PRESSURE applied SERVICE brake. The ACTIVE brake has an adjusta-
ble valve to control the braking speed. It is not recommended to use the ACTIVE brake
on flat ground as the ground drive provides sufficient braking.
If shaker requires to be towed out of a stuck position (such as mud or sand) always
make sure to turn ACTIVE brake to off position prior to tow vehicle towing or damage
to ground drive components will occur.
STEERING
The steering system is the same as in an automotive application. Turning the wheel in
desired direction of travel creates travel in that direction. Turning the wheel more or
less generates the desired amount of steering angle.
SHAKE
It is recommended to use the secondary throttle to set a fixed RPM for operation at
1,700 to 1,800 RPMs. All shake patterns have multiple frequencies and work best with
a fixed RPM in the 1,700 to 1,800 range. ALL patterns CAN be varied by using MORE
or LESS weight. The foot throttle can be used if extra variation is wanted. It is not rec-
ommended to exceed 2,000 RPMs while shaking as this reduces shake effectiveness.
ENGINE MONITOR or EXCELERATE DISPLAY
The in dash monitor is a multi function interface that displays vital engine information
as well as any engine fault codes. The monitor can be programmed to display only the
information that the operators prefers. The monitor is connected with the engines ECU
and communicates the information of the ECU. If there is a problem with the engine or
ECU the monitor will then display the ERROR CODE so the repair can be made.
HIGH and LOW GEAR
High or Low gear can be selected by the rocker switch located on the control console.
ONLY use HIGH gear when moving long distances NEVER use HIGH gear in tree to
tree shaking. USE LOW gear for tree to tree shaking. This machine is NOT equipped
for road use. It is recommended to ONLY move shaker on a trailer. DO NOT drive
shaker on PUBLIC roads. Moving shaker on rough roads at high speeds may cause
damage to chassis and head mounting systems.
