• If the cutting mechanism strikes a foreign object or if  
your machine should start making an unusual noise  
or vibration, immediately stop the engine and allow  
the machine to come to a complete stop. Disconnect  
the spark plug wire and move it away from the spark  
plug. Take the following steps.  
3. SERVICE  
• Use extreme care in handling gasoline and other  
fuels. They are extremely flammable and the vapors  
are explosive.  
• Store fuel and oil in approved containers, away from  
heat and open flame, and out of the reach of  
children. Check and add fuel before starting the  
engine. Never remove gas cap or add fuel while the  
engine is running. Allow engine to cool at least two  
minutes before refueling.  
Inspect for damage.  
Repair or replace any damaged parts.  
Check for any loose parts and tighten to assure  
continued safe operation.  
• Replace gasoline cap securely and wipe off any  
spilled gasoline before starting the engine as it may  
cause a fire or explosion.  
• Never attempt to attach or remove catcher bag when  
engine is running. Shut the engine off and wait for  
the impeller to come to a complete stop. The impeller  
continues to rotate for a few seconds after the engine  
is shut off. Never place any part of the body in the  
impeller area until you are sure the impeller has  
stopped rotating.  
• Extinguish all cigarettes, cigars, pipes and other  
sources of ignition.  
• Never refuel unit indoors because flammable vapors  
will accumulate in the area.  
• Muffler and engine become hot and can cause a  
burn. Do not touch.  
• Never store the machine or fuel container inside  
where there is an open flame or spark such as a gas  
hot water heater, space heater, clothes dryer or  
furnace.  
• Do not allow leaves or other debris to build up on  
engine's muffler. The debris could ignite and cause a  
fire.  
• Never run your machine in an enclosed area as the  
exhaust from the engine contains carbon monoxide,  
which is an odorless, tasteless and deadly poisonous  
gas.  
• Do not attempt to shred or chip material larger than  
specified in this manual. Personal injury or damage  
to the machine could result.  
• Do not operate engine if air cleaner or cover over  
carburetor air intake is removed, except for  
adjustment. Removal of such parts could create a  
fire hazard.  
• To reduce fire hazard, keep engine and muffler free  
of leaves, grass, and other debris build-up. Clean up  
fuel and oil spillage. Allow unit to cool at least 5  
minutes before storing.  
• Only use accessories approved for this machine by  
the manufacturer. Read, understand, and follow all  
instructions provided with the approved accessory.  
• Before cleaning, repairing, or inspecting, make  
certain the impeller and all moving parts have  
stopped. Disconnect the spark plug wire and keep  
wire away from spark plug to prevent accidental  
starting. Do not use flammable solutions to clean air  
filter.  
• If situations occur which are not covered by this  
manual, use care and good judgment. Contact your  
dealer for assistance.  
• Check the blade and engine mounting screws at  
frequent intervals for proper tightness. Also visually  
inspect blades for wear and/or damage (e.g., bent,  
cracked). Replace with blades which meet original  
equipment specifications.  
• Keep discharge chute deflector, chipper chute door,  
and all other guards and safety devices in place and  
operating properly.  
• Only operate unit in good daylight. Do not operate  
unit at night or in dark areas where your vision may  
be impaired.  
• Keep all nuts, bolts, and screws tight to be sure the  
equipment is in safe working condition.  
2. CHILDREN  
• Never tamper with safety devices. Check their proper  
operation regularly.  
Tragic accidents can occur if the operator is not alert to the  
presence of small children. Children are often attracted to  
the chipper-shredder and the chipping and shredding  
activity. Never assume that children will remain where you  
last saw them.  
• After striking a foreign object, immediately stop the  
engine, disconnect the spark plug wire from the  
spark plug, and thoroughly inspect the unit for any  
damage. Repair damage before starting and  
operating unit.  
• Keep children out of the work area and under the  
watchful eye of a responsible adult other than the  
operator.  
• Do not alter or tamper with the engine's governor  
setting. The governor controls the maximum safe  
operating speed of the engine. Overspeeding the  
engine is dangerous and will cause damage to the  
engine and to other moving parts of the machine.  
• Be alert and turn the unit off if a child enters the area.  
• Never allow children under the age of 16 to operate  
the chipper-shredder.  
WARNING - YOUR RESPONSIBILITY: Restrict the use of this power machine to persons who read,  
understand and follow the warnings and instructions in this manual and on the machine.

discharges materials with considerable  
velocity. Keep away from the area around  
the discharge chute. Always stop the  
engine and disconnect spark plug wire  
when removing or attaching the bag,  
changing containers, or removing the  
shredded material. Wear safety glasses  
and gloves whenever using your chipper-  
shredder.  
USINGYOUR CHIPPER-SHREDDER  
WARNING: Do not attempt to shred or  
chip any material other than vegetation  
found in a normal yard (i.e., branches,  
leaves, twigs, etc.).  
SECTION 9: MAINTENANCE  
• Leaves and small branches up to 1/2"  
diameter (maximum) can be fed into the  
hopper assembly when it is in the raised or  
lowered position.  
GENERAL RECOMMENDATIONS  
• Always observe safety rules when performing  
any maintenance.  
• For model 462B (5 H.P.), bulky material, such  
as stalks or heavy branches, up to 2” in  
diameter should be fed into the chipper chute.  
• The warranty on this chipper shredder does  
not cover items that have been subjected to  
operator abuse or negligence. To receive full  
value from the warranty, operator must  
maintain the chipper shredder as instructed in  
this manual.  
• For model 465A (8 H.P.), bulky material, such  
as stalks or heavy branches, up to 3” in  
diameter should be fed into the chipper chute.  
WARNING: Do not put material larger  
than is specified into the hopper, and/or  
into the chipper chute. Personal injury or  
damage to the machine could result.  
• Periodically check all fasteners and make  
sure these are tight.  
WARNING: Always stop the engine and  
disconnect the spark plug wire before  
• If it becomes necessary to push material into  
the chipper-shredder, use a small diameter  
stick -- NOT YOUR HANDS. The stick should  
be small enough that it will be ground up if it

performing  
any  
maintenance  
or  
adjustments. Never remove discharge  
chute till the engine has completely  
stopped.  
WARNING: Temperature of muffler and  
nearby areas may exceed 150o F(65oC).  
LOWERING THE HOPPER ASSEMBLY  
Avoid these areas.  
1. To lower the hopper assembly, use one hand to  
grasp the hand-hold at the top of the hopper  
assembly and lift slightly.  
LUBRICATION  
2. Pull out on the release knob, and lower the  
hopper assembly to the ground.  
Lubricate the pivot points on the release knob  
bracket, hopper assembly, chute deflector and once  
a season using a light oil.  
NOTE: For best performance, it is important to  
keep the shredding blade and the chipper blades  
sharp. If the composition of the material being  
discharged changes (becomes stringy, etc.) or if the  
rate at which the material is discharged slows down  
considerably, it is likely that the shredding blade and/  
or chipper blades are dull and need to be  
sharpened or replaced. Refer to Maintenance  
section.  
CLEANING  
• Clean engine periodically. Remove dirt and  
debris with a cloth or brush.  
• Frequently remove leaves, dirt and debris  
from cooling fins, air intake screen and levers  
and linkage. This will help ensure adequate  
cooling and correct engine speed.

• Clean the chipper shredder by running water  
from a hose through the hopper assembly  
and chipper chute with the engine running.  
Allow the chipper-shredder to dry thoroughly.  
SPARK PLUG  
• Service the spark plug according to the  
separate engine owner’s guide supplied with  
your chipper shredder.  
NOTE: Cleaning with a forceful spray of water is  
not recommended as water could contaminate the  
fuel system.  
REMOVING THE FLAIL SCREEN  
(See Figure 7)  
• Wash the bag periodically with water. Allow to  
dry thoroughly in the shade. Do not use heat.  
If the discharge area becomes clogged, remove the  
flail screen and clean area as follows:  
1. Stop engine, make certain the chipper-shredder  
has come to a complete stop and disconnect  
spark plug wire from the spark plug before  
unclogging the chute.  
2. Remove the two hand knobs on each side of  
the discharge chute (also called the chute  
deflector).  
3. Lift the discharge chute up, and keep it out of  
the way.  
4. Remove two hairpin clips from the clevis pins  
which extend through the housing. Remove the  
clevis pins.  
ENGINE OIL  
The engine oil is the most important “insurance  
policy” your new chipper shredder has. It protects it  
from excess wear and tear and helps the cooling  
process. It is important that you maintain the  
engine oil at the proper level and that it is changed  
on a regular basis.  
• Service the engine oil according to the  
separate engine owner’s guide supplied with  
your chipper shredder.  
5. Pull the flail screen from inside the housing.  
6. Clean the screen by scraping or washing with  
water.  
7. Reinstall the screen.  
8. Put the discharge chute back to its original  
position and tighten the hand knobs.  
AIR CLEANER  
The air cleaner prevents damaging dirt, dust, etc.,  
from entering the carburetor and being forced into  
the engine and is important to engine life and  
performance. Never run the engine without air  
cleaner completely assembled.  
NOTE: Be certain to reassemble the flail screen  
with the curved side down
