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

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-

G0594 Large Chipper/Shredder

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.

-11-

G0594 Large Chipper/Shredder

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

the gas tank, or performing maintenance and

repairs.

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.

the inlets or outlets, filling the gas tank, or

performing maintenance and repairs.

•

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.
