SECTION 1: SAFETY
For Your Own Safety, Read Instruction
Manual Before Operating this Machine
The purpose of safety symbols is to attract your attention to possible hazardous conditions. This
manual uses a series of symbols and signal words which are intended to convey the level of
importance of the safety messages. The progression of symbols is described below. Remember
that safety messages by themselves do not eliminate danger and are not a substitute for proper
accident prevention measures.
Indicates an imminently hazardous situation which, if not avoided,
WILL result in death or serious injury.
Indicates a potentially hazardous situation which, if not avoided,
COULD result in death or serious injury.
Indicates a potentially hazardous situation which, if not avoided,
MAY result in minor or moderate injury. It may also be used to alert
against unsafe practices.
This symbol is used to alert the user to useful information about
proper operation of the machine.

Additional Safety Instructions
for Chipper/Shredders
1. READ THIS ENTIRE MANUAL AND THE
BRIGGS & STRATTON® MOTOR MANU-
AL: These manuals contain proper operat-
ing and safety instructions for this chipper/
shredder.
5. CLOTHING: DO NOT wear loose clothing,
neckties, scarves, or jewelry which may
get caught in moving parts. DO NOT wear
clothing or gloves with pull ties or straps.
This type of clothing could get tangled with
material that is being shredded, pulling you
into the chipper/shredder.
2. SAFETY EQUIPMENT: Wear safety glass-
es, hearing protection, and gloves when
operating a chipper/shredder. Make sure
any bystanders are also wearing safety
equipment.
6. OPERATING LOCATION: Set up the chip-
per/shredder on firm, level, grass or dirt.
DO NOT set up the chipper/shredder on
gravel, asphalt, concrete, or stone. The
chips are expelled from the machine with
enough force to ricochet off of hard sur-
faces and cause serious injury. DO NOT
set up the chipper/shredder in a location
where sparks or heat from the motor could
cause a fire.
3. ENGINE OPERATION: Refer to the Briggs
& Stratton motor manual for operating
instructions and gasoline motor safety
warnings.
4. HAND SAFETY: DO NOT put hands or
other body parts into hopper, funnel, or
outlet while the blades are turning. The
chipper/shredder can drag you into the
blade, causing amputation of fingers, hands
or other body parts. DO NOT touch the
exhaust during or immediately after opera-
tion to prevent burns.
-6-

7. SECURE FOOTING: Placing the chip-
per/shredder on a slope or slippery surface
may cause the operator to fall into the
machine, causing burns from the motor, or
an amputation if an arm accidentally goes
into the hopper. Wear non-slip, closed toed
shoes or boots to maintain secure footing.
10. TURN OFF CHIPPER/SHREDDER: Turn
OFF the machine, allow all moving parts
to come to a complete stop, and discon-
nect the spark plug wire before moving the
machine, emptying the bag, unclogging
the inlets or outlets, filling the gas tank, or
performing maintenance and repairs.
8. JAMS AND CLOGGING: Turn the chip-
per/shredder OFF, allow all moving parts to
come to a complete stop, and disconnect
the spark plug wire before attempting to
free a jam or clog.
11. STARTING THE CHIPPER/SHREDDER:
Make sure the hopper and funnel are
empty when starting the machine. The pull
start cord may stop suddenly causing the
chipper/shredder to fall over or injure your
hand or arm.
9. FEEDING MATERIAL: Hold branches and
brush loosely, and allow the chipper/shred-
der to draw the material in. The machine
sometimes will draw material in very quick-
ly and your hand may be drawn in if you
are holding tightly. If the blades hit a hard
object, or if the machine begins to make
an unusual noise or vibration, immediately
shut the chipper/shredder OFF.
12. CLEANING CHIPPER/SHREDDER: Allow
the motor to cool off, then brush dust and
chip build-up off of the motor to prevent fire
or motor overheating.
No list of safety guidelines can be complete.
Every environment is different. Always con-
sider safety first, as it applies to your indi-
vidual working conditions. Use this and
other machinery with caution and respect.
Failure to do so could result in serious per-
sonal injury, damage to equipment, or poor
work results.
Like all machinery there is potential danger
when operating this machine. Accidents are
frequently caused by lack of familiarity or
failure to pay attention. Use this machine
with respect and caution to lessen the pos-
sibility of operator injury. If normal safety
precautions are overlooked or ignored, seri-
ous personal injury may occur.

SECTION 2: SET UP
Set Up Safety
Site Considerations
Location
The chipper/shredder must be placed on a firm,
flat, grass or dirt surface to prevent the machine
from tipping. DO NOT place the machine on con-
crete, asphalt, or other hard surfaces. The chips
could bounce up from the hard surface and cause
injury.
This machine presents
serious injury hazards
to untrained users. Read
through this entire manu-
al to become familiar with
the controls and opera-
tions before starting the
machine!
Working Clearances
Consider the length of the material to be pro-
cessed through the machine and make sure that
there is enough height above the chipper/shred-
der to accommodate the material.
Unpacking
Make sure the unit is located close to the area
where the chips are going to be used to reduce
carrying.
The Model G0594 was carefully packed when it
left our warehouse. If you discover the machine
is damaged after you have signed for delivery,
please immediately call Customer Service at
(570) 546-9663 for advice.
Stay clear of the discharge area. Make sure all
bystanders, children, pets, or objects that you do
not want damaged or covered in chips, are clear
of the discharge area.
Save the containers and all packing materials for
possible inspection by the carrier or its agent.
Otherwise, filing a freight claim can be difficult.
When you are completely satisfied with the con-
dition of your shipment, you should inventory the
contents.

To shred twigs, leaves, and brush:
To chip branches:
1. Slowly pour the material into the hopper. DO
NOT try to stuff too much material in at one
time or the machine will jam.
1. Stand to the side of the hopper and make
sure you have a stable stance and firm foot-
ing.
2. Use a 1" diameter branch to push the mate-
rial into the hopper if necessary (see Figure
9). DO NOT use your hands!
2. Remove twigs and smaller branches from the
branch if they might catch on the edges of the
funnel and prevent the branch from going in.
3. Place branches up to 3" diameter into the
funnel, thick end first, and allow the blades to
draw the branch into the funnel (see Figure
10).
Figure 9. Shredding leaves.
Note: Move the throttle to the idle position, or
turn the chipper/shredder OFF, when not actively
shredding or chipping.
Figure 10. Chipping branches.
3. Turn OFF the machine (see the Briggs &
Stratton motor manual for instructions), allow
all moving parts to completely stop, and dis-
connect the spark plug wire before moving
the machine, emptying the bag, unclogging
the inlets or outlets, filling the gas tank, or
performing maintenance and repairs.
4. When finished chipping, turn OFF the
machine, allow all moving parts to come to a
complete stop, and disconnect the spark plug
wire before moving the machine, emptying
the bag, unclogging the inlets or outlets, filling

Shredding Tips:
Chipping Tips:
•
Feed material into the chipper/shredder slow-
ly. If the motor begins to bog down, you are
feeding too fast.
•
•
•
DO NOT feed material in excess of 3" diame-
ter into the funnel. Large branches will cause
the motor to stall.
•
•
Roots and dirty material will dull or damage
the blades.
Chipping wood when it is green is easier on
the machine. The blades will stay sharper
longer.
Remove the chips often. Allowing the chips
to pile up to the outlet will cause the outlet to
clog.
The chipper/shredder will work best if the
blades are sharp. Rotate, sharpen, or replace
the blades as soon as chipper/shredder per-
formance begins to deteriorate.
•
Avoid shredding wet leaves or brush to
reduce clogging. If you must shred wet mate-
rial, alternate wet and dry material.

•
•
Remove the spark plug wire to prevent unau-
thorized starting.
Empty the bag before storing to keep the
mulch from rotting in the bag.
Visual Inspection
Place the chipper/shredder in a dry, level
area. If the chipper/shredder is tipped it may
leak oil and gas.
Before and after using the chipper/shredder,
closely inspect the machine for loose parts and
damage.
•
•
•
•
DO NOT store the chipper/shredder near an
ignition source, such as a wood stove, gas or
electric heater, or an appliance or heater with
a pilot light.
•
Check the hopper, hopper guard, and funnel
for cracks, holes, and loose bolts.
•
•
Check the box frame for cracks or damage.
Store the chipper/shredder in a well ventilat-
ed area. DO NOT store the chipper/shredder
in an area that will allow toxic gas fumes into
areas inhabited by humans or animals.
Check the entire machine for loose bolts or
screws.
•
•
Check the blades and hammers for cracks
and dings.
Close the discharge chute deflector and
place the covers over the hopper and the
funnel to prevent objects or critters from get-
ting into the machine.
Check the engine oil level. See the Briggs &
Stratton motor manual for specifications.
When storing for more than 30 days, fol-
low the instructions in the Briggs & Stratton
motor manual for long term storage.
Cleaning
Clean the Model G0594 after each use. Allow the
motor to cool and remove the spark plug wire.
Brush off or vacuum wood chips and wipe off the
remaining dust from the exterior of the machine
with a dry cloth. DO NOT rinse off the chipper/
shredder with water. Remove any chips or debris
from the hopper and the discharge chute.
It is much harder to clean the machine if you allow
it to sit for a while after use. You may need to use
an engine cleaner to remove the built up resins
from the motor. Engine cleaners are available at
most auto parts stores.
