1 INTRODUCTION
Congratulations on your choice of a Baumalight
Brush Mulcher to complement your mulching
operation. This equipment has been designed and
manufactured to meet the needs of a discriminating
buyer for efcient grinding of stumps.
The rotor is hydraulic powered by the hydraulic
system on your skid steer.
Replaceable bearings are provided at major pivot
points for extended service life.
Safe, efcient and trouble free operation of your
brush mulcher requires that you and anyone
else who will be operating or maintaining the
brush mulcher, read and understand the Safety,
Operation, Maintenance and Troubleshooting
information contained within the Operator’s
Manual.
This manual covers the Baumalight Brush Mulcher,
model MS348. Use the Table of Contents as a
guide to locate required information.

party for recycling.
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.
1.1 Overview
The brush mulcher 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 mulcher and the safe use
of the mulcher 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 mulcher
tool will not come across metallic objects, stones
or other materials.
Brush mulcher 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

4.5 Detach Brush
Mulcher
^ 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� Disconnect hydraulic hoses�
4� Shut off engine and remove key�
1. Park skid steer on a level surface.
2. Lower mulcher to the ground.
3. Shut off engine and remove key.
4. Disconnect hydraulic hoses.
5. Detach skid steer from mulcher. See skid steer
Operator’s Manual.
1. Verify all reectors and Slow Moving Vehicle
(SMV) sign are visible.
2. Raise brush mulcher slightly off ground.
3. Verify hydraulics are disengaged.
4. Travel at a reasonable and safe speed.
^ WARNING
To prevent bodily injury from rotating
cutting wheel, be sure to disengage
hydraulics before transporting mulcher�
4.6 Transporting
13

During the rst few hours of use, avoid hitting
stones as much as possible to allow the carbide
teeth to wear slightly.
This can be done by keeping the cutting wheel
above ground level. Brand new carbide tips are
razor sharp and can chip and shatter easily when
they hit hard objects.
Once the razor sharpness has worn away, the tips
do not chip as easily.
Observing these precautions will extend the life of
the carbide teeth and reduce operating expenses.
4.7 Carbide Teeth
Break-In
1. First, operate all functions in a clear area with
skid steer at idle speed to get a good feel for
the controls before you actually move into any
brush.
2. Choose low density brush and move into it
slowly, do not expect to get the rst area done
fast.
3. Slow travel speed if pressure surges up close
to max psi, doing this will greatly reduce rotor
jambs, and with practice, will almost eliminate
jambs.
4. Run throttle only at half speed for rst time
users.
5. Operate with mulcher slightly raised until you
have a better feel how much the unit can take.
^ WARNING
Always turn off the skid steer and
disengage hydraulic drive before
getting off the seat and approaching the
cutting wheel�
^ WARNING
Wear an approved respirator (N95 Type
as a minimum)�
Follow local, state and federal
regulations�
The health effects from exposure to
wood dust are due to chemicals in the
wood or chemical substances in the
wood created by bacteria, fungi, or
molds�

4.9 Field Operation
^ 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 off engine and remove key�
^ WARNING
Never operate brush mulcher when
other people are in the vicinity�
Do not allow riders on skid steer�
^ WARNING
Never operate brush mulcher when
other people are in the vicinity� Debris
can be thrown several feet from cutting
area� Keep all shields in place�
^ WARNING
Clean machine thoroughly before
service or maintenance procedures�
The health effects from exposure to
wood dust are due to chemicals in the
wood or chemical substances in the
wood created by bacteria, fungi, or
molds�
1. Attach brush mulcher to skid steer. See Attach
Brush Mulcher in this section.
^ WARNING
Prevent serious injury or death�
Operating unit must be equipped with a
forestry guard to protect the operator�
2. Lower mulcher so skid plates are on ground.
3. Set engine speed to low idle and engage
mulcher.
4. Slowly increase engine speed to high idle.
Verify mulcher is operating smoothly and start
travel.
5. If mulcher stalls, stop movement, slightly raise
mulcher and allow rotor to regain speed. Slow
ground speed to prevent further stalling.
^ WARNING
Moving parts can crush and cut�
Keep clear of moving components�
Lockout operating unit before clearing
jams�
^ WARNING
Never approach brush mulcher before
cutting wheel has come to a complete
stop�
15

If the rotor stalls, stop rotor motion, raise slightly
and try again.
1. If still stalled, lower unit so teeth tips dig slightly
into sod, a log or stump.
2. Reverse hydraulic ow to mulcher. Reversing
the ow does not power the rotor in the reverse
direction, it only opens the hydraulic lock on
the rotor. The rotor will not be powered in the
reverse direction.
3. Drag the rotor across sod, a log or stump in
reverse direction to dislodge the jam.
^ WARNING
Always turn off the skid steer and
disengage hydraulic drive before getting
off the seat and approaching the cutting
wheel�
