Panasonic PTO 540 RPM User Manual

PTO-Driven 6" Wood Chipper  
OWNER’S MANUAL  
Read carefully and understand RULES FOR SAFE OPERATION and instructions  
before operating. Failure to follow the safety rules and other basic safety precautions  
may result in serious personal injury.  
Item #180100  
WORK AREA  
Keep everyone — especially children — away from the area of operation.  
Anyone who has not read this manual and received instructions from a  
qualified person should not be in the area.  
Provided labels on the unit advise the user of proper hitch dimensions and  
maximum safe operating speed. Check that proper danger labels are supplied with  
the drive-line (replacements are available from your drive-line supplier). Provide  
easy-to-understand instructions for proper drive-line operation, maintenance and  
repair in the operator’s manual.  
PERSONAL SAFETY  
Stay alert, watch what you are doing and use common sense when operating a  
chipper. Do not use a chipper while you are tired or under the influence of  
drugs, alcohol or medication. A moment of inattention while operating a chipper  
may result in serious personal injury.  
Do not attempt to operate the chipper until you have read and understood the  
owner’s manual.  
Always keep the guards and chip deflector installed properly while operating  
the chipper.  
Keep the decals in place and in good repair. The factory or your dealer will furnish  
new decals upon request.  
Keep hair, hands, feet and other extremities out of and away from the hopper.  
Make sure there are no loose ends or strings to be caught by the machine.  
Point the discharge chute away from doorways, sidewalks, or any areas where  
your view is obstructed. The chute should be pointed downwind when possible or the  
fines will blow into your eyes and down your neck.  
WEAR PROTECTIVE GEAR:  
EYES — Wraparound ANSI-approved safety glasses.  
EARS — Ear plugs  
HANDS — Leather gloves  
FEET — Steel-toed boots  
LEGS — Heavy pants  
ARMS — Long-sleeved shirt  
Always use the appropriate eye and ear protection and other safety equipment.  
Safety equipment such as dust mask, non-skid safety shoes and a hardhat used for  
appropriate conditions will reduce personal injuries.  
Avoid accidental starting. Disconnect chipper from PTO when not in use, and when  
moving chipper to another work area.  
Never leave the chipper running unattended.  
Do not attempt alterations, repairs, or adjustments while the chipper head is  
turning. Always disconnect the PTO and stop the motor.  
ALWAYS make sure the feed roll drive-shaft and pivots are properly lubricated.  
ALWAYS make sure the feed roll clutch is properly lubricated and the clutch  
releases when the handle is pushed toward the chute.  
ALWAYS make sure the PTO shaft does not come apart or bottom out during  
the normal lifting range.  
Check the chip pile to see if the blades need to be serviced. Long slivers in the  
chip pile are a good indication that the blades are dull and need sharpening.  
CAUTION: Turn the chipper head over by hand before applying power to  
make sure that the head is clear, all the bolts are clear and the knives clear the  
case and cutter bar.  
DRIVE-LINE SAFETY CHECKLIST  
DRIVE-LINE SPECIFICATIONS The first step toward a safe application is  
to specify and test the drive-line to make sure it operates properly  
under expected field conditions.  
Specify and test the proper size joints and telescoping members based upon the  
power required by the implement, speed of rotation, joint angles, shock loads, and  
expected life. More information may be found in all drive-line manufacturers’ catalogs.  
Design and test the hitch angle to prevent the drive-line from:  
Extending beyond the recommended maximum length.  
Bottoming out.  
Reaching a position that allows joints to lock.  
Exceeding the maximum allowable angle for constant velocity (CV) joints.  
Specify and test telescoping members to allow the lowest possible thrust loads,  
considering the expected working conditions.  
Specify and test torque limiters to control excessive shock loads. Where necessary,  
specify and test overrunning clutches to prevent inertial loads from overpowering the  
tractor.  
Specify and test torque limiters to control excessive shock loads.  
Where necessary, specify and test overrunning clutches to prevent inertial loads from  
overpowering the tractor.  
HAZARD REDUCTION The second step in specifying a safe drive-line  
application is to eliminate as many hazards as possible.  
On drive-lines with torque limiting or overrunning devices, specify that the device be  
positioned on the end of the drive-line by the implement.  
For implement connections which require bolts or set screws, select and/or supply  
hardware which minimizes protrusions.  
For tractor PTO shaft connections, specify a safety type yoke (twist or slide collar) to  
minimize protrusions.  
Provide a proper clearance zone for the operation of the drive-line to avoid damaging  
the shielding components.  
Some common areas of interference are:  
Three point linkage.  
Extended or eye loop hitch pins.  
Hydraulic hoses.  
GUARDING Hazards which cannot be eliminated effectively must be  
guarded against at all times.  
The PTO master shield, integral drive-line shield and implement input connection  
shield should provide an interactive guarding system.  
Provide instructions by labels or manuals. The implement should be used only with  
the tractor’s PTO master shield in place.  
Specify and test an integral drive-line shield with end cones which will overlap, but not  
interfere with the PTO master shield or implement input connection shield.  
Provide an implement input connection shield to interact with the integral drive-line  
shield to provide guarding of the shaft coupling and any torque limiting device installed  
on the drive-line.  
Check that all routine maintenance of the drive-line can be done without removal of  
the shields.  
MACHINE OPERATION  
CAUTION! Turn the chipper head over by hand before applying power to make  
sure that the head is clear, all the bolts are clear and the knives clear the case and cutter  
bar.  
CAUTION: Do not move the unit while the flywheel is turning. Block the wheels and  
set the brake while running the head.  
1. The chipper is a flywheel-and-knife type of chipper, not a shredder. The blades  
actually chip the limbs as they are fed into the head. The blades must be sharp to  
operate properly. Dirt, rocks, nails, or other foreign material will shorten blade life.  
2. Before operating the chipper, review the machine checklist. After turning the chipper  
by hand and making sure there are no obstructions in the head, start the tractor and  
raise the chipper until the PTO shaft is within 15 degrees of straight.  
3. Start the chipper slowly with the PTO engaged, and release the PTO clutch slowly.  
Gradually increase speed until the tractor PTO speed is 540 RPM.  
4. The material will feed into the head more easily if you start the pieces with the large  
end first. The feed roll will fold branches as they are pulled into the hopper.  
Occasionally, a limb fork may have to be cut to feed properly.  
5. If the material stops feeding, sometimes a little push on the long end of the limb will  
help.  
6. If the material stops the feed roll, release the feed roll clutch by pushing it toward the  
chute. Hold the clutch in the disengaged mode, and pull the material out of the  
hopper. Release the feed roll clutch and the feed roll will turn again.  
NOTE: Cut only clean material, or blade life will be shortened.  
7. Watch the discharge chute while operating the unit. If the chips stop flowing, stop  
feeding material into the unit by moving the feed roll clutch handle toward the chute  
and pulling the material from the hopper. Most of the time this will be enough to clear  
the chips out of the unit. If the unit slows down noticeably, first shut off the PTO  
power, then the tractor, and remove the key.  
8. Unplug the head by turning it backwards by hand with the discharge chute and top  
section of the wrapper off.  
9. Remove the chips from the top of the head. If this fails, remove the clean-out door,  
located on the lower part of the front side-plate of the chipper below the main shaft,  
then work the chips out of the case.  
10. Replace the clean-out door after all the chips are removed, being sure to use both  
the lock washers and flat washers.  
11. Do not operate the unit without the deflector in place.  
12. Before stopping the chipper, be sure the all of the material is out of the head and out  
of the feed roll.  
13. All of the material in the chute must be gone or the unit could jam on a small piece of  
material. This can usually be cleared by turning the unit backwards by hand.  
14. To replace the blades, take the PTO shaft out of gear, then turn off the tractor. The  
blades on most models are replaced or turned by removing the inspection plate on  
the side opposite the chute.  
15. Unhook the feed roll springs, block the feed roll to maximum position, and, with an  
Allen wrench on the chute side and a socket on the other, remove the bolts. (Be  
careful not to drop any part inside.)  
16. Remove the blade, clean the blade pocket and turn or sharpen the blade. Replace  
blade.  
17. Torque the bolts to 50 ft.-lbs. in all holes so the bolts are straight through the  
flywheel. A small screwdriver or ice pick works well to clean pockets for the Allen  
wrench. Replace the inspection plate and reattach the springs.  
18. Turn over by hand before applying power.  
19. The cutter bar should be adjusted to 0.010 to 0.030" from the blades by loosening  
the bolts in the bottom of the chute in the slotted holes and moving the bar on slots.  
20. Bolts are to be torqued to 35 ft.-lbs.  
21. The cutter bar can be reversed and/or resharpened.  
22. Dull blades cause many problems, such as: Seeming lack of power, plugging of the  
discharge chute, rough cutting with more vibration than usual, feed roll shaft broken,  
main bearing housing broken, main bearing working loose and the flywheel or  
blades hitting the case or bed knife, feed roll kicking out of gear, and not feeding.  
INSPECTION, MAINTENANCE AND CLEANING  
WARNING: Always stop the PTO, turn off the engine and remove the key before  
performing any inspection, maintenance, adjustments or cleaning.  
Lubricate:  
PTO shaft — 2 zerks on universals once a day with multipurpose grease.  
Slip Joint — Lubricate with multi-purpose grease.  
Feed roll pivot — 2 zerks on underside of chute end. Multipurpose grease every 4 to 8  
hours of operation. If dust or fine particles make pivot bind, unhook feed roll springs,  
use cleaning solvent on pivot while moving up and down, wipe off, lubricate slides,  
and replace springs.  
Feed roll drive-shaft — Zerk on feed roll drive-shaft lubricates both the slide and both  
universal joints. Add multipurpose grease until grease shows at both universals every  
4 to 8 hours of operation, particularly before each use. Occasionally remove and  
thoroughly clean this assembly.  
Feed roll clutch — While feed roll shaft is off, lubricate the feed roll clutch inside and  
outside with multipurpose grease.  
Gear box — Check label on the gear box for gear box lubrication.  
Check all bolts, set-screws and fasteners after running four hours, and once per day  
thereafter.  
Check for loose belts and broken pulleys, loose springs, dry slides and proper  
lubrication of both feed roll drive-line and feed roll clutch.  
The main drive belts on the chipper need co be tight. To tighten these belts, first  
loosen the four bottom nuts that hold the jack-shaft bearing. Loosen them about three  
turns, then move the nuts on the top of the bearings down an equal amount. Keep the  
jack-shaft parallel with the main shaft. Torque the bottom nuts to 80 ft.-lbs.  
The belts of the main drive on the PTO chipper should be checked every 8 hours of  
operation.  
Look for cracks, looseness or other signs of deterioration. For best performance,  
replace with a matched set of eight belts.  
The feed roll drive belt can be adjusted by first loosening the four bolts that hold the  
worm gear box to the base, then moving the gear box away from the chute and  
re-torques the bolts to 40 ft.-lbs.  
All decals and safety instructions should be kept clean and legible. It is the operator’s  
responsibility to replace the decals as needed (they will be mailed at no charge).
