Operating Precautions

!

CAUTION

READ, UNDERSTAND AND FOLLOW ALL OF THE

PRECAUTIONS BELOW.

Always perform the pre-start checklist before starting the engine.

• Never operate the chipper/shredder without safety guards and covers

in place.

• Keep hands, feet, and clothing away from rotating parts. Keep

clear of chipper/shredder tines at all times.

• Use extreme caution when operating on or crossing gravel drives,

walks, or roads. Stay alert for hidden hazards or trac.

• If a limb or branch becomes stuck in the chipper inlet or debris

becomes clogged in the shredder hopper, stop the engine, remove
the wire from the spark plug, manually remove the obstacle before
restarting the engine.

• Engine muer will be hot from operation. Do not touch it with

bare skin or a severe burn may result.

• Do not run the engine indoors; exhaust fumes are deadly.

• Do not overload the chipper/shredder by trying to process too much

debris at one time or force a limb in the chipper inlet that is a greater
diameter than the machine’s capacity.

• Never operate the chipper/shredder on slippery surfaces.

• Use only attachments and accessories approved by the manufacturer.

• Never operate the chipper/shredder without good visibility or

adequate light.

• Take precautions when leaving the machine unattended. Stop the

engine, wait for all moving parts to stop, and make certain guards and
shields are in place.

• Shut o the engine when leaving the operating position for any

reason. Wait for all moving parts to stop before attempting to dislodge
debris, or limbs.

• e chipper/shredder blades are extremely sharp. Avoid contact with

bare hands at all times.

Operation

!

CAUTION

DO NOT ATTEMPT TO START ENGINE

BEFORE ADDING OIL TO ENGINE

e engine is shipped from the factory without oil.

Use only the recommended weight of oil for a 4-cycle engine (See

Engine Operation Manual).

OIL

YOU MUST ADD ENGINE

OIL BEFORE STARTING

THE ENGINE.

NOTE: Upon start-up and shut-down, you may hear the metal-to­metal sound of the triangular hammers and J-hammers positioning
themselves on the rotor. is is normal.

Chipper Operation

e chipper is designed to handle tree limbs and branches up
to 3”. e chipping knives also permit the processing of coarse
organic matter like corn stalks. Tree branches must be inserted large­end first into the chipper inlet. Since occasional kick-backs may
occur, always stand off to the side of the unit. Allow the self-feeding
action of the unit to draw the sticks in.

NOTE: CHALK THE WHEELS BEFORE OPERATION!

Shredder Operation

e shredder is designed to shred light brush, leaves, and
other soft but bulky organic waste. As material, no larger than
1/2 inch in diameter, is loaded into the shredder hopper it is pulled
into the path of the triangular and J-hammers by air flow.

Operating Location

Select an area with firm, level ground, covered by dirt or grass.
Do not operate on wet or slick surfaces, or near bystanders.
Locate and organize the materials to be processed so that you
don’t have to walk in front of the inlet or discharge openings,
and so you have adequate room to work safely.

!

CAUTION

DO NOT ALLOW DEBRIS TO COLLECT

ON THE ENGINE.

A DANGER OF FIRE OR DAMAGE

TO THE ENGINE MAY RESULT.

Operation

Preparation for Operation

Fill Engine Crankcase with Oil

1. Add oil according to engine manual. Do not overll. Use
a clean, high quality detergent oil. Use no special additives
with recommended oils. Do not mix oil with gasoline.
Oil level must be full. Check the oil level by removing oil
ll plug. Oil level should be up to the bottom of the ll
plug opening (see Figure 7).

2. Always check oil level before starting engine. Refer to
engine manual for capacity and type of oil to use.

Pre-Start Inspection

1. Make sure safety shields are in place and nuts & bolts are
secure.

2. Check oil level in engine crankcase. See your engine
manual for procedure and specications.

3. Inspect air cleaner for cleanliness.

4. Check the fuel supply. Fill the fuel tank no closer than 1
inch from top of tank to provide space for expansion. See
your engine manual for fuel recommendations.

5. Be sure spark plug wire is attached and spark plug is
tightened securely.

6. Examine underneath and around engine for oil or fuel
leaks.

7. Inspect fuel hoses for tightness and to ensure there is no
fuel seepage.

8. Look for signs of engine damage.

9. Remove excessive debris from muer area and air inlets
near the recoil starter.

Operation

Starting the Engine

Turn fuel shut-off valve to ON position.

Cold Starts

1. Move the engine control lever to the left (choke) position (see
Figure 8).

2. Pull recoil handle out slowly one time and allow to return
normally.

3. Pull recoil handle out slowly but with force, and allow rope to
return normally.

Note: You must overcome the inertia of the ywheel.

4. When engine starts, gradually move the engine control lever to the
right (fast) wide open position to increase engine speed.

Restarting A Warm Engine

Restarting an engine that is already warm from previous running does
not normally require use of the choke.

1. Move the engine control lever to “Run” position.

2. Pull the recoil handle out slowly but with force until engine starts.
Allow rope to return normally. Repeat until engine starts.

3. Adjust the engine control lever speed to “fast” (wide open position)
for best chipper/shredder operation.

Figure 8

Idle Speed

Use the “slow” position on the engine control lever to reduce stress
on the engine when chipping or shredding is not being performed.
Lowering the engine speed to “idle” will help extend the life of the
engine, as well as conserve fuel and reduce the noise level of the
equipment.

Operating Speed

For normal shredding and chipping, set the throttle lever to “fast”.

Shutting Down

1. To stop the engine at any time, move the engine control lever to
the STOP position.

Note: Due to the inertia of the ywheel, extra time is required for the
engine to fully stop.

2. Close fuel shut-o valve.

13

Operation

Chipping Recommendations

• Prune branches down close to the main branch to make feeding them into the
chipper inlet easier.

• Large, hard, dried tree branches that resist chipping can be processed by
rotating them as you alternately insert and retract them.

• Material conditions vary, sometimes exceeding the capacity of the equipment.
If the material to be chipped is extremely hard, kicks back forcefully when
being fed into the chipper inlet, or cannot be easily controlled, remove
the material immediately and set it aside. Do not attempt to process these
materials.

• If additional force is required to insert materials into the chipper, the blades
probably need to be sharpened. Consult the Troubleshooting and Repair
section of this manual, or see your authorized dealer.

• Maintain control of the materials you are feeding to prevent them from
whipping around.

• Do not insert short pieces of material into the chipper inlet by hand. Use a
larger piece of material to push them into the chipper inlet.

Shredding Recommendations

• Don’t overload the shredder by dumping large volumes of material into the
hopper opening.

• Alternate loads of wet and dry material to prevent the discharge from
becoming plugged.

• Never use any object to force material into the shredding chamber. It could
get caught in the shredding hammers, kick back, whip around, or cause injury
to the operator.

OPERATION TYPE OF MATERIAL SIZE METHOD

Shredding Dry or moist organic material Branches and twigs up to 1/2” Alternately chip or shred
