Replaceable bearings are provided at major pivot
points for extended service life.
Safe, efcient and trouble free operation of your
Tree Saw requires that you and anyone else
who will be operating or maintaining the Tree
Saw, read and understand the Safety, Operation,
Maintenance and Troubleshooting information
contained within the Operator’s Manual.
This manual covers the DXA530 Baumalight Tree

TheTreeSaw is designedto be usedbyexperienced
operators, trained in the safe operation of an
excavator and trained in the hazards related to
using the tree saw and the safe use of the tree saw
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 tree saw will
not come across metallic objects, stones or other
materials.
Tree saw is not designed for use in hazardous

4�3 Machine Components 4�4 Initial Startup
Perform an initial startup and carefully move tree
saw and boom to all positions to verify hoses and
wires will not be damaged.
Carefully watch the circled areas in below images
to be sure hoses and wires are not pinched or
kinked. Reroute if damage may occur.
Baumalight does not provide these hoses
and wires, and they are not covered by the
Baumalight warranty�
15

4�5 Attach Tree Saw
^WARNING
To prevent injury or machine damage
put transmission in park�
Never position yourself between
excavator and tree saw�
Only experienced and properly trained
operator’s should operate the excavator
and tree saw�
1. Read and follow all safety instructions.
2. Attach tree saw to excavator. See Operator’s
Manual.
3. Verify pins are secure in the correct position.
4. Connect hydraulic hoses. Verify hydraulic
hoses are clear of pinch areas and moving
parts.
5. (If Equipped) Connect optional remote pendent
connector (A) to excavator 12 volt power
supply.
A
6. Move to a clear open area to test functions.
1. Verify all reectors and Slow Moving Vehicle
(SMV) sign are visible.
2. Raise tree saw slightly off ground.
3. Verify hydraulics are disengaged.
4. Travel at a reasonable and safe speed.
^WARNING
To prevent bodily injury from rotating
blade, be sure to disengage hydraulics
before transporting tree saw�
4�6 Transporting
16

4�8 Carbide Teeth Break-In
4�7 Detach Tree Saw
^WARNING
Prevent serious injury or death�
1�
2� Engage parking brake�
3� Disconnect hydraulic drive�
4� Shut off engine and remove key�
1. Park on a level surface.
2. Lower tree saw to the ground.
3. Shut off engine and remove key.
4. Disconnect hydraulic hoses and optional
remote pendent connector (if equipped).
5. Detach tree saw from excavator. See
Operator’s Manual.
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.
The teeth bolts must be retightened every ten
minutes for the rst hour of use on a new tree saw.
17

• First, operate all functions in a clear area with
throttle at low idle to get a good feel for the
controls before you actually move into any
brush.
• Slow cutting speed if pressure surges up close
to max psi. Doing this will greatly reduce blade
stoppage.
• Run throttle only at half speed for rst time
users.
• Move the tree saw slowly until you have a
better feel how much the unit can take.
• The machine is equipped with a front push
bar to push brush or small trees over. This will
allow the tree saw teeth to contact the lower
portion of the brush and the blade to cut it off.
• Each operator must experiment to nd
a technique that works for them in their
application.
^WARNING
Always turn off excavator and disengage
hydraulic drive before getting off the
seat and approaching the blade�
^WARNING
Drilling, sawing, sanding or machining
wood products can expose you to wood
dust, a substance known to the State of
California to cause cancer�
Avoid inhaling wood dust or use a dust
mask or other safeguards for personal
protection� For more information go to
www�P65Warnings�ca�gov/wood�
4�9 First Time User Tips
^WARNING
Wear an approved dust mask or
respirator�
Follow local, state and federal
regulations�
