1 INTRODUCTION
Congratulations on your choice of a Baumalight
Tree Saw to complement your pruning, trimming
and clearing operation. This equipment has been
designed and manufactured to meet the needs
of a discriminating buyer for ecient clearing of
brush, shrubs and trees.
The blade is hydraulic powered by the hydraulic
system on your skidsteer.
Replaceable bearings are provided at major pivot
points for extended service life.
Safe, ecient 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 DSM230 and DSM530
Baumalight Tree Saw. 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.
When this machine is worn out and no longer in
use, it should be returned to the retailer or other
party for recycling.
OPERATOR ORIENTATION - The directions left,
right, front and rear, as mentioned throughout this
manual, are as seen from the operator’s seat and
facing in the direction of travel.
1�1 Overview
The Tree Saw is designed to be used by
experienced operators, trained in the safe
operation of a skidsteer 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 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 tree saw is misused. Misuse
may also cause damage to the machine carrying
the implement.

^ WARNING
To prevent injury or machine damage
put transmission in park�
Never position yourself between
skidsteer and tree saw�
Only experienced and properly trained
operator’s should operate the skidsteer
and tree saw�
1. Read and follow all safety instructions.
2. Attach tree saw to skidsteer. 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. Move to a clear open area to test functions.
4�5 Detach Tree Saw
^ WARNING
Prevent serious injury or death�
1� Park machine on rm, level surface.
2� Engage parking brake�
3� Disconnect hydraulic drive�
4� Shut o engine and remove key.
1. Park on a level surface.
2. Lower tree saw to the ground.
3. Shut o engine and remove key.
4. Disconnect hydraulic hoses.
5. Detach tree saw from skidsteer.
6. See Operator’s Manual.
12

1. Verify all reectors and Slow Moving Vehicle
(SMV) sign are visible.
2. Raise tree saw slightly o 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 4�7 Carbide Teeth Break-In
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.
13

• 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
and an angled 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 o.
• For tall brush, you can use the angled push
bar to push the brush over and cut it o close
to ground. Each operator must experiment to
nd a technique that works for them in their
application.
^ WARNING
Always turn o the skidsteer and
disengage hydraulic drive before
getting o the seat and approaching the
blade�
4�9 First Time User Tips
4�8 Hydraulic Connections
^ WARNING
Pressurized uids can penetrate the
skin�
Disconnect and lock out power source
before disconnecting and/or connecting
hydraulic hoses�
The tree saw is equipped with three hoses,
pressure, return and case drain. Hydraulic
couplers are not provided with the tree saw. You
must install couplers and connect your skidsteer
pressure, return and case drain hoses to the tree
saw hoses.
Skidsteer hoses must be the same size as the
tree saw hoses. Using smaller diameter hoses will
decrease hydraulic ow.
