Operation Notes  
At engine start-up, the engine of your chipper operates under no load until approximately  
1200-1400 RPM’S at which speed the centrifugal clutch engages and begins driving the  
rotor.  
Proper rotor speed is 2400 RPM +/- 200 RPM.  
When viewed from the operator zone, the flywheel turns in a clockwise direction. This  
rotation pulls branches into the chipper.  
Always wear protective gloves and safety glasses during operation of the chipper.  
If it becomes necessary to push material into the chipper hopper, only use a wood stick,  
never your hands or anything steel.  
Never assume you know where the knife is. You don’t know where it is. Always keep  
hands out of the chipper hopper.  
Keep area of discharge clear of people, animals, buildings, glass or anything else that will  
obstruct clear discharge, cause injury or damage. Wind can also change discharge  
direction, so be aware.

SECTION IV - CHIPPING  
THIS CHIPPER WAS DESIGNED FOR CHIPPING LIMBS OR BRANCHES.  
NEVER USE THIS MACHINE FOR ANY OTHER PURPOSE AS IT COULD  
CAUSE SERIOUS INJURY.  
SAFETY FIRST  
Always wear protective gloves and safety glasses during operation of the chipper.  
Never allow your hands or any part of your body or clothing inside the chipper hopper or  
discharge area of the chipper.  
Keep all protective guards and warning labels on the machine and in good working  
condition.  
Always stand clear of the discharge area when the chipper is running.  
Keep your face and body back from the chipper hopper to avoid being struck by any  
material that may bounce back.  
Keep proper balance and footing while operating the chipper.  
If it becomes necessary to push material into the chipper hopper, only use a wood stick,  
never your hands or anything steel.  
Never assume you know where the chipper knife is. You do not know where it is.  
Keep area of discharge clear of people, animals, buildings, glass or anything else that will  
obstruct clear discharge, cause injury or damage. Wind can also change discharge  
direction, so be aware.  
Always keep hands out of the chipper hopper.  
Never operate the chipper without the chipper hopper in place.  
Do not transport the chipper while the engine is running.  
Do not refuel the engine while it is hot, warm, or running.  
Do not cover the chipper while the muffler is still hot.  
PROCESSING LIMBS OR BRANCHES  
Your chipper can process dry or green material.  
Remove side limbs, branches or twigs from main branch.  
Feed branch into chipper hopper.  
Keep branch at same angle as chipper hopper.  
As the branch becomes short and is inside the chipper hopper, finish processing it by  
pushing it into the chipper with the next branch.  
If branches are 2” or larger in diameter, feed only one branch at a time into the chipper.  
If branches are smaller than 2”, more than one at a time can be fed into the chipper.  
Green branches process quicker and easier than dry branches.  
Soft wood processes easier than hard wood.  
When chipping branches, sometimes a tail will be left at the end of the branch (usually  
green wood) that will increase in length as you chip. To avoid this, rotate or twist the  
branch as you feed it into the chute.  
Rotating the branch as you feed it into the machine will improve chipping performance.

SECTION V - MAINTENANCE AND STORAGE  
IMPORTANT: The knife should be checked for sharpness and the nuts and bolts attaching it to the  
flywheel for tightness every 8-10 hours of operation.  
IMPORTANT: Every time you perform maintenance or any kind of service or check on the knife, be sure  
to check the gap between the knife and wear plate for proper setting.  
NOTE: A knife gauge has been provided with your machine. It is 1/16th” thick and should be used to set  
the correct gap between the knife and wear plate.  
If the cutting mechanism strikes any foreign object or if your machine should start making an  
unusual noise or is vibrating, stop the engine, disconnect the spark plug wire from the spark  
plug. Allow the engine to cool before you;  
a. Inspect and examine for obvious damage.  
b. Check for loose parts, bolts, and nuts.  
1. When not in use, your chipper should be stored out of the reach of children. Be sure there are no gasoline  
fumes in the storage area. For long periods of storage (over winter), refer to the engine owner’s manual.  
2. After every 8 hours of operation, lubricate the chipper side and drive side bearings with multi-purpose lithium  
grease. Also, check the bearing collar set screws regularly to be sure they are tight. If they are loose, reset  
them with Loctite 243, obtainable at any hardware store.  
3. You will find information included referring to operation and maintenance of the chipper engine. Look it over  
carefully. BE CERTAIN TO SERVICE THE ENGINE BEFORE YOU START IT.  
4. When the steel chipping knife (item #21, pg. 30) needs replacing or sharpening, refer to the section on  
removal, sharpening and re-installation.  
5. Care must be exercised when sharpening the knife to maintain the correct bevel and a straight edge. Refer  
to sharpening directions. When you install a knife, the clearance between the knife and wear plate must be  
checked and set. This clearance or gap should be set to 1/16” (see figure 1).  
6. To adjust this clearance, loosen the three ¼” nuts and bolts (item #16 & #22, pg. 30) holding the wear plate  
in place. The wear plate can be slid up or down (in or out) to achieve the correct gap setting.  
7. Take the knife gauge and slide between the knife and wear  
plate. If the gap is set correctly, the knife gauge will lightly  
touch both the knife and wear plate. If the gap is too small,  
you will not be able to get the gauge between the knife and  
wear plate. If the gap is too large, there will be excess room  
between knife gauge, knife and wear plate. Tighten the nuts  
and bolts when the wear plate is in the correct position. Be  
certain the flywheel rotates without hitting anything before  
starting the chipper.  
8. If the gap between the wear plate and the knife is not set  
correctly, you will have excessive vibration when chipping  
and the blade will seem to be dull. This should be checked  
every 8-10 hours of operation.  
9. If at any time it becomes necessary to disassemble the  
chipper for repairs, the chipper disk (item #13, pg. 30) must  
be re-installed in exactly the same position on the rotor shaft.  
NOTE: Proper gap setting is critical to the proper operation of your machine.

REMOVAL, SHARPENING AND RE-INSTALLATION OF CHIPPER KNIFE  
HOW TO REMOVE THE KNIFE  
Stop the engine.  
Remove the spark plug wire and keep away from the spark plug.  
Disconnect battery at negative terminal.  
Remove both access covers from the chipper basic machine.  
Rotate the chipper disk until the three countersunk screws and nylock nuts attaching  
the knife to the flywheel are visible through the access doors.  
Clean out the heads of the allen screws with an awl or sharp tool.  
Insert a 3/16” allen wrench into the heads of the screws.  
Use a ½” socket and ratchet to remove the nylock nuts from the screws.  
Remove all three allen screws and nuts in this manner.  
If your chipper has two knives, rotate the flywheel 180 degrees and repeat above  
process.  
KNIFE SHARPENING  
You should never attempt to sharpen the chipper knife (or knives) freehand.  
It is extremely important that the 45 degree angle be maintained consistently for  
proper performance.  
The chipper knife (or knives) should be taken to a machine shop for proper  
sharpening.  
If your chipper is equipped with two knives, it is extremely important that they be  
balanced to equal weights to eliminate vibration.  
If your chipper is equipped with two knives, replace in pairs only.  
Excessive heat generated during the sharpening process will damage knives and  
weaken the metal. Be sure the knives are not overheated.  
KNIFE INFORMATION  
The chipper knife should be checked routinely for sharpness.  
Using a dull knife (knives) will decrease performance and cause excessive vibration  
that will cause damage to the chipper.  
How many times a knife can be sharpened is determined by how much material needs  
to be taken off to sharpen or to compensate for dents or gouges.  
A new chipper knife has 5/16” measurement between the short side bevel edge and  
the knife mounting holes. See figure 2.  
Figure 2

Download from Www.Somanuals.com. All Manuals Search And Download.  
The knife should never be sharpened to the extent that more than 3/32” is taken off  
this measurement.  
Once this measurement is below 7/32” (see figure 3) the knife should be replaced.  
If you are unable to remove dents or gouges with these guidelines, replace the knife.  
Figure 3  
KNIFE INSTALLATION  
Clean chipper disk where knife is going to be attached.  
Visually inspect the chipper disk slot and knife mounting area and be sure they are  
clean and that the knife will be able to mount flush against the chipper disk.  
Visually inspect and clean the knife.  
Hand tighten the knife to the chipper disk with bolts and nylock locking nuts. If you are  
installing a new knife, use the new hardware that comes with the knife when attaching  
it to the chipper disk.  
Tighten the center nut and bolt.  
Tighten the outer nut and bolt.  
Tighten the inner nut and bolt.  
Double check all three for tightness one more time.  
If your chipper has two knives, rotate the flywheel 180 degrees and repeat above  
process.  
WEAR PLATE  
The wear plate should have a square edge and be free of dents or gouges.  
The wear plate can be sharpened by hand, but as with the knife, do not overheat  
during the sharpening process. This will change the characteristics of the steel and it  
should be replaced.  
Check the gap between the knife and wear plate every time any adjustments are done  
to either piece, or every 8-10 hours of operation.

AFTER ANY BLADE OR WEAR PLATE MAINTENANCE OR ADJUSTMENT, ROTATE  
THE CHIPPER DISK BY HAND. WATCH AND LISTEN CAREFULLY FOR ANY UNUSUAL  
NOISES, CLICKING OR VIBRATION. IF ANY OF THESE ARE DETECTED, INSPECT THE  
MACHINE FOR DAMAGE, REPAIR OR REPLACE ANY DAMAGED PARTS AND CHECK  
FOR ANY LOOSE PARTS AND RETIGHTEN.  
KNIVES MUST BE CHECKED AND MAINTAINED!  
KNIVES MUST BE SHARP!  
BE SURE TO REINSTALL THE KNIFE CORRECTLY AND DOUBLE  
CHECK FOR TIGHTNESS!  
CHANGING OIL  
Your chipper is equipped with an oil drain valve to make changing the oil easy.  
The valve is located on the engine, on the towing side of the machine.  
Place engine level.  
Disconnect spark plug wire and keep it away from spark plug. Disconnect battery (if  
equipped with electric starter) at negative terminal.  
With engine OFF but still warm open oil drain valve and drain oil into appropriate  
receptacle.  
Note: To open valve, push in and turn counterclockwise.  
Close oil drain valve.  
Remove dipstick (if equipped) or oil fill cap.  
Add new oil (28 ounces). Fill to FULL line on dipstick or to point of overflowing at oil fill  
cap. Do not overfill.  
Replace dipstick or oil fill cap.

INSTRUCTIONS FOR ADJUSTING OR REPLACING BELT  
BELT ADJUSTMENT  
The belt on your chipper should deflect 3/8” under three pounds of pressure as shown in  
figure 1 below. If it doesn’t, adjust per the following directions.  
Figure 1  
Remove belt guard.  
Loosen engine bolts.  
Tighten or loosen the nut on the belt tensioner until you have the correct tension as  
shown in figure 1.  
Retighten engine bolts.  
Check alignment of the clutch (item #12, pg.28) with the drive pulley (item #13, pg 28)  
by placing a straightedge across both faces as shown in figure 2. If adjustment is  
necessary, correct alignment by moving rotor pulley in or out on the rotor shaft. Do  
not make adjustment by moving the clutch on the engine shaft.  
Replace belt guard.  
Figure 2  
BELT REPLACEMENT  
To replace the belt, follow the above belt adjustment directions.  
After you have loosened the engine bolts, remove the old belt and replace it with a  
new one.  
Set belt tension and alignment per above directions.  
NOTE: Check and re-tighten belt after initial break-in period, one hour of use.

CENTRIFUGAL CLUTCH TECH TIPS  
CLUTCH PART NO. 030-0202  
THE SHOES AND SPRINGS ON THE CLUTCH ARE NORMAL WEAR ITEMS. IF YOU  
NOTICE DECREASED PERFORMANCE OF THE CLUTCH THEY SHOULD BE CHECKED  
AND REPLACED IF NECESSARY.  
The clutch on your machine is designed for rugged, dependable service, however, it is  
important to understand the limitations of a clutch. A clutch is designed to provide load free  
starting of the engine, and slippage under excessive overloading of the driven application.  
These features help protect the engine from damages such as broken crankshafts and  
starters.  
The clutch obtains its power from engine RPM’s. The lower the engagement speed, and the  
higher the maintained engine speed, the more torque the clutch can transfer to the driven  
unit. Do not operate at less than full RPM’s.  
At engine start-up, the engine of your chipper operates under no load until approximately  
1000-1200 RPM’S at which speed the centrifugal clutch engages and begins driving the  
rotor.  
Proper rotor speed is 2400 RPM +/- 200 RPM.  
Do not tamper with the engine’s governor setting. The governor controls the maximum  
safe operation speed and protects the engine. Over-speeding the engine is dangerous  
and will cause damage to the engine and to the other moving parts of the machine. See  
your authorized dealer for engine governor adjustments.  
Become familiar with successful operating conditions and avoid those that can  
overload and damage the machine.  
Do not overload or attempt to chip material beyond manufacturers recommendation.  
Personal injury or damage to the machine could result.  
Learn to recognize the sound of the machine when it is overloaded.  
If the machine becomes jammed by overloading or any other cause, stop the machine  
immediately.  
If you jam the machine and do not stop the engine, it can:  
Burn the belt.  
Ruin the clutch.  
Only your operator experience will tell you how fast you can successfully feed limbs into  
the machine.  
Clutch damage can be costly and it may not be covered under warranty. For this  
reason, it is important that you immediately shut off the machine if it becomes  
jammed.
