1. INTRODUCTION
1.1 Overview
Congratulations on your choice of a Baumalight 3-Point Stump Grinder to complement your stump grinding operation. This equipment has been designed and manufactured to meet the needs
of a discriminating buyer for efcient grinding of
stumps.
Model 3P24 has 34 teeth on a 24 in. cutter and models 3P34 and 3P40 have 54 teeth on a 34 in. cutter. This means less cutting for each tooth resulting in longer tooth life and smoother cutting for less wear on the tractor. Heavy tooth population
makes ner mulch and smoother operation.
The cutting wheel is powered by the PTO (540) on your tractor with the swing and lift cylinders activated by the standard remote hydraulic connectors on the tractor.
Grease zerks and replaceable brass bushings are provided at major pivot points for extended service life.
The debris shields is standard equipment on all stump grinders. It is recommended that the stump grinder never be operated without one.
When this machine is worn out and no longer in use, it should be returned to the retailer or other party for recycling.

4.3 Driveline Dimension
To accompany the variety of 3 point hitch geometry available today, the driveline can be too long for some machines or too short for others. It is very important that the driveline be free to telescope but not to bottom out when going through its working range. If the driveline bottoms out, the bearings on both the machine and tractor PTO shaft will be overloaded and fail in a short time.
To determine the proper length of the driveline, follow this procedure:
1. Attach stump grinder to tractor but do not attach driveline.
2. Raise grinder until the input shaft is level with tractor PTO shaft.
3. Measure dimension (A) between locking grooves on tractor PTO shaft and grinder input shaft.
4. Measure same dimension (B) on compressed driveline.
1. Subtract machine dimension (A) from uncut driveline dimension (B). This dimension determines how much too long the driveline is.
2. Add 1 in. (25 mm) to the dimension to be sure it doesn’t bottom out, to determine cut off dimension (C).
3. Use a hacksaw to cut dimension (C) from both ends. Cut both plastic tubes and metal cores.
5. If compressed driveline dimension (B) exceeds the machine dimension (A), driveline must be cut.
When cutting driveline, follow this procedure:
12
4. Use a le to remove burrs from cut edges.
5. Assemble shaft.
6. Make sure shaft can telescope freely. If it does not, separate and inspect for burrs or cuttings on shaft ends. Be sure it telescopes freely before installing.
5. OPERATION
5.1 Preparation For Use
^ WARNING

5.8 Carbide Teeth Break-In
5.9 First Time User Tips
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.
Before you begin, make sure the tractor is turned off and the PTO drive is disengaged.
Stand to the side of the stump grinder and observe the center point on the bottom of the cutting wheel. Now sit on the tractor seat and observe the center point again. This point will appear different depending on where you are positioned. This can be very deceiving! Familiarize yourself with the view of the stump grinder from the tractor seat.
Test all operating functions in an open area with the tractor at idle speed to get a feel for the controls. Take your time.
Start with a small stump. Make the rst pass then
disengage the PTO drive and get off the tractor to see how much you have removed.
Get off the tractor after each pass to check the progress. The cutting wheel is shielded from view
when sitting on the tractor seat so it is difcult to
accurately determine the progress. The ability to judge the positioning improves with practice. Do
not expect to get the rst stump done quickly.
^ WARNING
Always turn off the tractor and disengage the PTO 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 moulds.
19
5.10 Field Operation
^ WARNING
Entanglement in a rotating drive line can cause serious injury or death.

6.2 Maintenance
Maintenance Chart
General Inspection Inspect the unit for any buildup of
contamination (dirt, stones, etc.). Hydraulics Check hydraulic hoses and ttings for leaks. Daily Cutting Teeth Check and replace one at a time as
necessary. The teeth on the outer edge of
the wheel wear faster and are more prone to
chipping. With daily use expect to replace 5
to 10 teeth per week. (See Replace Cutting
Teeth in this section.) Deector Shield Pins Lubricate pins so deector can move freely. Every 6 hours. Pivot Pins Lubricate nine (9) pivot pins. Every 10 hours. Gearbox Oil Change gear box oil. Use synthetic 90W
gear oil. Capacity is 1.5 L (1.5 qts.). Cutting Wheel Retaining Nut Torque to 176-190 N•m (130-140 lb-ft.) Only if cutting wheel is

7. TROUBLESHOOTING
PROBLEM CHECK SOLUTION
Cutting wheel does not spin. Cutting wheel jammed. Remove material from cutting wheel.
Verify PTO drive line is connected properly. Connect drive line to tractor.
Slip clutch is slipping. Remove jam from cutting wheel.
Cutting wheel does not have much power. Slip clutch is slipping. Check to determine if the slip clutch is
hot. Use Caution: This Can Be Very Hot! A hot clutch does NOT grip.
Slippage on the clutch occurs if there is more power than the unit is rated for: Model 3P24 is rated for 20-60 hp input. Model 3P34 is rated for 50-80 hp input. A bigger tractor can be used if it is idled down as this will decrease the output power of the engine.
Take smaller passes (less cutting) to decrease the strain on the clutch.
Turn the flow control knob to a lower number (1) to reduce the strain on the slip clutch.
Be careful when tightening the tension setting on the slip clutch as this could put excess strain on the gear box.
Tractor is not able to lift 3-point. Tractor is too small. Move link pins to the top position on the
stump grinder to add leverage.
Cutting wheel cannot be lifted high enough. Stump too tall. Cut stump shorter.
Shorten top link on 3-point hitch.
Cutting wheel cannot be lowered far enough. Top link not correct length. Lengthen top link on 3-point hitch.
No movement on cylinders. No oil flow. Check for plugged or reversed hydraulic
lines.
Adjustment valve is closed. Open adjustment valve.
