This unit utilizes a high speed cutting disk to fell trees,
the speed of the disk results in clean and efficient
cutting. Operation of this unit is broken in to 5 steps.
STEP 1: Cutting
The operator should be safely seated in the carrier with
all necessary safety equipment in place; carrier should
be started and revved to¾ of maximum rpms, When
the desired tree is chosen (16" or below diameter on
CFB16) the carrier should be aligned in front of the
tree. The Hydraulic system should then be engaged,
upon engagement the cutting disk should be allowed
to spin up to the maximum rpms; once max rpms have
been achieved, the carrier should then be moved
forward slowly, keeping the cutting disc level, allow the
cutting disk to move into the tree at a steady feed rate.
The feed rate of the unit is based on many factors
including carrier size, and hydraulic flow. The correct
feed rate can only be determined by the operator
FEEDING THE CUTTING DISK INTO A TREE TOO
FAST WILL RESULT IN THE DISK BEING UNABLE TO
RECOVER ITS RPMS AND STALLING OUT
A
WARNING: Cutting disk should be fed
into tree in a level position. DO NOT feed
cutting disk into tree at an angle. Doing
so may result in bent blade and/or bearing
damage.

WARNING: DO NOT attempt to raise or
lower unit while disk is cutting tree. Doing
so may result in bend blade and/or damage
bearings.
If the desire of the operator is to cut and drop, simply
continue feeding the disk through the tree until the
trunk of the tree contacts the top of the CFB16's tower
at which point the tower will push the tree away from
Basic Operation
the carrier and the tee will fall. If the desire is to cut and
carry the tree, the operator will not push the tree over,
but proceed to step 2.
STEP 2: Holding
Holding tree(s) is achieved by the use of two grapple
arms powered by two cushioned cylinders. The arm
movements are controlled by two in cab buttons
1
for
closing,
1
for opening, the holding function is used
while transporting tree(s) to drop piles. To operate the
hold feature while cutting, the operator must wait to
start to engage until ¾ of the way through a tree; At
which point press and hold the closing control button
until closing movement stops, when closing movement
stops, tree is in held position; allowing operator to move
the tree (see step 5)
A
DANGER: Do not use arms to pull disk into
tree, leveraging stalled blade into uncut
tree, will result in bearing/cutting disk
damage.
STEP 3: accumulating
If the operator desires to cut multiple smaller diameter
trees without having to drop them individually at the
drop pile, the CFB16 has a built in accumulator arm.
This arm is controlled by two in cab buttons;
1
for
closing,
1
for opening. To operate the accumulator
feature, the operator must have the first tree in the
held position (see step 2). The operator then moves
the carrier to the next desired tree, when the unit is in
position to cut, no more than 2 feet away from the tree
to be cut; the operator then engages the accumulator
arm to temporarily keep the previously cut tree from
falling off of the butt plate. The Holding arms can then
opened and the tree is cut as outlined in step 2; after
both trees are in the held position, the accumulator
arm can be safely opened* ready to repeat the process.
*NOTE: Once the accumulator arm slides out from
between the trunks and back into the open position, the
operator will need to press the close button once more
on the holding arms, the space the accumulator arm
occupied will be empty causing the load to be loose.
A
DANGER: The accumulator arm (CFBl 6)
is for temporarily retaining trees(s) it is
not designed for holding, never attempt to
carry trees without use of holding arms.
