1 INTRODUCTION
Congratulations on your choice of a Baumalight
Skid Steer Brush Cutt to complement your brush
cutting operation. This equipment has been
designed and manufactured to meet the needs of
a discriminating buyer for ecient brush cutting.
The Brush Cutt has four blades and can cut a
path 72 inches wide. The unique blade design
reduces the brush to mulch. Controlling the Brush
Cutt is done completely from the cab of the skid
steer providing the ability for precise control and
operator comfort.
Safe, ecient and trouble free operation of your
Brush Cutt requires that you and anyone else
who will be operating or maintaining the Brush
Cutt, read and understand the Safety, Operation,
Maintenance and Troubleshooting information
contained within the Operator’s Manual.
This manual covers the CF772 Baumalight Skid
Steer Brush Cutt. Use the Table of Contents as a
guide to locate required information.
Keep this manual handy for frequent reference
and to pass on to new operators or owners. Call
your Baumalight dealer, distributor or the factory
if you need assistance, information or additional
copies of the manuals.
OPERATOR ORIENTATION - The directions left,
right, front and rear, as mentioned throughout this
manual, are as seen from the skid steer driver’s
seat and facing in the direction of travel.
The brush cutter is designed to be used by
experienced operators, trained in the safe
operation of a skid steer and trained in the hazards
related to using the brush cutter and the safe use
of the cutter for the intended purpose. Operators
will require personal protective equipment to
reduce the risk from some hazards that cannot be
completely eliminated or controlled by the design
of the tool.
Care is required to ensure that the brush cutter
tool will not come across metallic objects, stones
or other materials.
Brush Cutt tools are not designed for use in
hazardous atmospheres where there is a risk
of re or explosion due to ammable gases or
vapors. Use in hazardous, explosive atmospheres
is prohibited.
Serious injury or death of the operator or bystanders
may be caused if the tool is misused. Misuse may
also cause damage to the machine carrying the
implement.

^WARNING
Prevent serious injury or death caused
by unexpected movement:
1� Park skid steer on a level surface�
2� Engage skid steer park brake�
3� Disengage hydraulic drive�
4� Shut o engine and remove key.
^WARNING
Never operate brush cutter when other
people are in the vicinity� Debris can be
thrown several feet from cutting area�
Keep all shields in place�
Do not allow riders on skid steer�

4�7 Field Operation
^WARNING
Wear an approved dust mask or
respirator�
Follow local, state and federal
regulations�
1. Attach cutter to skid steer. See Attaching/
Detaching in this section.
2. Check the area you plan on working for any
large stones or metal objects. Hitting these
objects is very dangerous and will decrease the
life of your blades and the machine in general.
3. The blades must be free to rotate before you
start hydraulic oil ow. The blades need to be
running at full speed before you start cutting
brush.
4. If the blades stop rotating, raise deck a few
inches until blades are rotating at full speed.
If blades do not start rotating immediately after
deck has been raised, stop oil ow on skid
steer, lock all controls and check that blades
are able to rotate freely.
5. If the brush is not as ne as desired, try slowing
your travel speed or continuously travel the
same path until brush is shredded to the
desired level.
6. When you are nished, stop oil ow and idle
skid steer for a few minutes to allow skid steer
engine to cool before shut down.

5�4 Motor Shaft Seal
The cutter is equipped with a case drain line that
is to be routed to the skid steer hydraulic reservoir.
It is normal for a hydraulic motor to have a slight
amount of internal leakage.
The case drain line will allow this internal leakage to
be returned to the reservoir, preventing excessive
pressure on the motor seal.
If the case drain line is not connected or becomes
obstructed, the zero leak relief valve will vent the
pressurized hydraulic oil to the atmosphere. The
zero leak relief valve will self reset after hydraulic
pressure reduced.
^ WARNING
Pressurized uids can penetrate the
skin�
Keep bystanders away from machine
during operation�
Atiny, almost invisible leak can penetrate
the skin, thereby requiring immediate
medical attention�
If hydraulic oil is coming out of the zero leak relief
valve, shut down machine immediately. Inspect the
case drain line connection and lines. Contact your
dealer if case drain lines and connection are good.
NOTICE
Environmental hazard�
Clean up any spilled hydraulic oil
immediately�
A properly installed case drain protected by a zero
leak relief valve will save the work of replacing the
motor shaft seal and also improve the eciency of
your hydraulic system.

6 TROUBLESHOOTING
PROBLEM CHECK SOLUTION
Rotor does not spin. Rotor jammed. Remove material from rotor. See
Clearing Jams.
Low oil level. Check oil level in skid steer. Add if
necessary.
Low oil ow. Check ow control on skid steer. See
your dealer.
Can rotor be turned by
hand with the hydraulics
disconnected?
If yes, check for a stuck relief valve.
If no, determine if the rotor is stuck or
the motor or over hung load adaptor are
stuck.
If the motor or overhung load adaptor is
stuck, remove and determine cause of
problem.
Rotor rotates slow or sluggish. Low oil. Check oil level in skid steer. Add if
necessary.
Oil lter plugged. Replace skid steer oil lter.
Relief valve not set
properly. Set relief pressure 2500 - 3500 psi.
Low oil ow. Check ow control on skid steer. See
your dealer.
Excessive vibration. Cutting blades worn or
missing.
Replace worn, broken or missing
blades.
Debris lodged in rotor. Remove debris.
Hydraulic oil coming out of zero
leak relief valve.
Case drain connector for
proper connection and
line for obstructions or
pinched line.
Connect case drain line if not connected.
Replace line if damage, obstructed or
pinched.
Combo coupler seals on
skid steer.
Combo coupler seals may be leaking,
allowing pressurized uid to escape to
the case drain line.
