Overview
The CFB 16 is a compact hydraulic felling head designed
to cut and carry single trees up to 16" in diameter. The
CFB16 consists of a mounting plate, a deck, a tower, 2
conventional grapple arms ered by 2 cushioned
hydraulic cylinders, a hydraulic motor, a bearing block, a
disk hub, a cutting disk, multiple hoses, couplers, and
valves. The CFB 16 makes use of 1 hinged accumulator
arm, and an additional hydraulic cylinder, which allows
operators to bunch multiple trees at the same time.

Safe Maintenance & Maintenance Schedule| 4
Safe Maintenance & Maintenance Schedule
Daily maintenance
Failure to inspect or maintain the CFB16 daily may
cause premature wear of components, resulting in
component failure. Failure of components may result in
damage to unit, persons, and/or property. DFM
accepts no liability on any damage to property or
persons from failure to observe regular inspection and
maintenance procedures.
Tools & Skill Requirements
*Daily maintenance of your equipment requires basic
tools, skill, and expertise.
Welding & hydraulic repair work should be done by a
licensed professional. For a Turbo Saw maintenance
specialist in your area please contact our service
department at [phone] or email contact@
doughertymfg.com
Daily maintenance checklist:
Grease all pivot points
• Inspect all cutting teeth for tightness (tighten if
necessary)
• Check cutting disk for vertical play (excessive vertical
play is an indication of bearing failure)
• Inspect all hydraulic lines/couplers for leaks (replace if
necessary)
Practice Safe Maintenance
Always work in a clean and dry environment. Never work
on a running machine or on a machine with moving
parts. Lower unit onto hard surface, disengage unit from
carrier, engage brake, turn off carrier and remove key.
Allow the unit to cool off before maintaining. Caution,
parts may be hot, sharp, or hazardous. Follow guidelines
on protective equipment and clothing.
*If you are not a licensed welder or hydraulic specialist
call your DFM for maintenance assistance.
Beware of toxic fumes when maintaining your skid steer
saw. Weld, smolder, or torch in a well ventilated area.
Metal, paint, and other materials can be toxic when
heated. Please be mindful of your chemical environment
and wear the proper equipment when maintaining your
skid steer saw such as a breathing mask and/or welders
mask.

Applying Grease | 5
Applying Grease
Open the arms and look for grease zerks, then close the
arms and look for grease zerks.

Remove the back panel to access the grease zerks
on the base of the cylinders.

Rotating / Replacing Teeth | 6
2 3 41
Replace
The following signs indicate that the disc saw teeth
need to be replaced:
Damaged teeth
Missing segments of teeth
Unbalanced load
Worn cutting edges
Tools
A 1/4” hex bit socket and a ratchet are needed to
remove and fasten the teeth.
Note: Tighten to 30 to 40± Torque
Rotating & Changing The Teeth
The carbide teeth should be rotated every 125 hours or
when cutting rate has noticeably decreased. Depending
on cutting conditions, the teeth may need to be rotated
sooner or later.
DO NOT RUN A CUTTING DISC WITH BROKEN OR
MISSING TEETH. AN UNBALANCED LOAD COULD
OTHERWISE OCCUR CAUSING EXCESSIVE WEAR ON
THE BEARINGS.
IF THE SAW IS OPERATED WITH A TOOTH MISSING,
THE BACKING BLOCK WILL WEAR QUICKLY. IF THE
BACKING BLOCK IS WORN, IT MUST BE CUT OFF
AND A NEW ONE WELDED ON.
Rotate
Most wear occurs on the outside edge of the tooth.
A tooth needs to be rotated when cutting time has
noticeably increased. Rotate them 90° so that the top
edge faces out.
NOTE: When the tooth comes in contact with the
ground, the bottom edge will wear as well. If both the
bottom and outside edges of the tooth are noticeably
worn, rotate the tooth 180°.

Removing / Replacing the Blade | 7
Removing / Replacing the Blade
tWARNING: The cutting disc is heavy. Be careful and use assistance.
DISK REMOVAL: The cutting disk can be removed by simple hand tools, and can be done in the eld. Blade removal
must be done with unit off carrier.
Step 1: Disengage Hydraulics and Electronics
Disengage all hoses and electric lines (use zip tie to coil
them safely out of way)
Step 2: Place the Unit on the Ground
While the unit is attached to the carrier, roll the carrier
arms completely forward until unit is horizontal; lower
unit onto hard stable surface and disengage the
carriers lock feature. Unit is now disengaged from
carrier. Move carrier away from unit and work area.
Step 4: Remove the Blade
Once these bolts are removed the disk can be
taken off the unit; in order to fully remove the
disk, it needs be to be slipped past the slide rails.
To do this, the disk is rst pulled off the hub,
then slide all the way to the right of the deck,
Step 3: Remove The Bolts
Remove the 4 bolts that attach the skid plate using
an impact wrench and a ¾” socket. There are 2 more
bolts underneath the skid plate; remove these bolts.
To replace the disk back on the unit, repeat these steps
in reverse.
NOTE: Make sure to face the cutting edge of the teeth
towards a clockwise rotation from the bottom.
At this point it’s pivoted allowing the
left side of the disk to clear the rails.

Attaching the Feller Buncher | 8
Attaching the Feller Buncher
Mounting the unit to the carrier consists of 3 steps;
failure to follow these steps may result in the unit
disengaging from the carrier, causing injury or death.
STEP 1: The Mounting Plate
The CFB16 is equipped with a universal mounting plate;
to attach the unit, drive the carrier toward the plate,
hook the plate with the carriers brackets, and roll the
carriers brackets backwards. After the operator has
successfully “hooked” the brackets onto the plate, the
operator then engages the brackets lock function. The
operator must then visually conrm the lock function has
been successfully engaged.
STEP 2: Connecting the Hydraulics
The next step is to connect the hydraulic hoses from
the unit to the carrier’s auxiliary ports. CFB16 ships with
the correct hydraulic couplers for use on the carrier
specified. Standard flow units make use of 2 hoses to
operate, high flow models require a 3rd hose, acting as
a case drain to relieve excess back pressure. CASE
DRAIN LINE MUST BE ATTACHED AT ALL TIMES
WHEN IN USE, FAILURE TO DO SO WILL RESULT IN
DAMAGE TO THE HYDRAULIC SYSTEM, AND VOID
WARRANTY
The operator must line up the units couplers with the
correct couplers on the carrier side, and snap them into
place; the operator then rotates the couplers collar ¼
turn to engage the couplers lock function. Operator should
then visually confirm the couplers are all attached, and the
lock functions have been engaged.
STEP 3: Connecting the Electronics
The 3rd step is to hook up the electrical system. The CFB16
makes use of an electric over hydraulic circuit to engage
certain valves required to function properly, This unit will
ship with one of two options. Option 1: for carriers with a
pin connection system the unit will ship with a pin connector,
and will utilize the carriers own joystick buttons to operate.
To hook up this option,the operator will plug the pin
connector into the carrier side socket. Option 2: for units
not equipped with pin connection system; the unit will ship
with a wiring harness; this wiring harness will contain 4
sealed buttons, connection plugs, and a length of electrical
wire; to hook up this option the operator will need to tap
into a 12 volt source, as well as attach the buttons in cab in a
convenient location. (See Diagram)
