• Do not operate shredder in
gaseous or explosive
atmospheres.
7. USE OF AN EXTENSION CORD
WARNING: To reduce the risk of
electric shock, use only with a
U.L listed outdoor extension cord.
Always connect extension cords
to a fused line or one protected by
a circuit breaker.
• Never use a damaged cord -
always inspect your extension
cord for loose or exposed wires
or damaged insulation.
• Dg not abuse cord - keep cord
away from heat, oil and sharp
edges.
• Do not yank cord from
receptacle.
• We recommend using No. 16
AWG wire size for lengths up to
10O.ft., and No. 14 or larger
wire size for longer lengths.
• To prevent disconnection of
the shredder cord from
extension cord when operating,
make a knot as shown in
Figure 4A.
• Blowing a fuse or tripping a cir¬
cuit is an indication that too
many devices are drawing
power from the circuit. Deter¬
mine the cause and correct it.
Do not install a higher capacity
fuse.
8. DISCONNECT SHREDDER
FROM EXTENSION CORD:
• when being transported.
• prior to cleaning or making
adjustments.
• when not in use.
• when removing or replacing
parts.

turned off before reconnecting
cord interlock or plugging unit into
extension cord.
12. USE SHREDDER PROPERLY:

job except for which it is
intended.
• Do not attempt to shred hard
objects such as metal, glass,
stones, masonry materials,
ceramics, bones or plastics.
• Do not attempt to shred ropes
or rags. This will cause the unit
to bind up.
In the event that one or more of
the above materials is
mistakenly fed into the
shredder, follow the procedure
outlined in safety instruction
no. 3.
• Do not operate a damaged
shredder. Have it repaired

proper footing and balance at all
times. Position yourself behind the
unit away from the discharge
chute when feeding material into
the feeder funnels.
14. DO NOT SWITCH MOTOR OFF -
until the shredder is completely
empty, as it may be difficult to
restart.
15. STORE SHREDDER INDOORS-
when not in use, shredder should
be stored indoors in a dry
location, out of reach of children.
16. MAINTAIN SHREDDER WITH
CARE - Do not operate a
damaged shredder. Follow all
product care and maintenance
instructions.
Double-Insulation
Your tool is DOUBLE-INSULATED to
give you added safety. This means
that it is constructed throughout with
TWO separate “layers" of electrical
insulation or one DOUBLE thickness
of insulation between you and the
tool’s electrical system.
Tools built with this insulation system
are not intended to be grounded. As a
result, the extension cord used with
your tool can be plugged into any
conventional 120 volt electrical outlet
without concern for maintaining a
ground connection.
NOTE: DOUBLE-INSULATION does
not take the place of normal safety
precautions when operating this tool.
The insulation system is for added
protection against injury resulting from
a possible electrical insulation failure
within the tool.
CAUTION: When servicing Double
Insulated Tools, USE ONLY
IDENTICAL REPLACEMENT
PARTS. Replace or repair damage
cords.

Use the side feeder for twigs and
branches up to one inch in
diameter after they have been
prunned. (See Fig. 6)
7. Remove any soil or stones from
materials before shredding to
prevent damage or duliing of
blades.
8. The shredder Is equipped with
an integral overload switch to
protect the motor from
damage. If overload occurs, the
shredder will automatically be
switched off. It can then be
switched on again after a cool
down period of one or two
minutes.

11. Do not turn the shredder off until
all shredded material has been
cleared. Any material that is left
inside the feeders may jam the
unit and prevent it from operating
when switched on again. If this •
occurs, follow the procedure
outlined above in Item 8.
12. It is adviseable to shred damp
and dry materials alternatively as
this will prevent sticking and
clogging of the shredder.
Dry materials should be ground
last to absorb any moisture which
may be left in the shredder. This
will aid in clearing the unit.
13. When operating the shredder it
is important that the drive belt is
run at the correct tension.
DURING THE FIRST HOUR OF
USE, THE TENSION MAY
NEED TO BE ADJUSTED
SEVERAL TIMES. The
