ELECTRICAL SAFETY
■Read and understand all safety instructions
before connecting the product to the mains
supply.
■Power plugs must match the outlet. Never
modify the plug in any way. Do not use
any adapter plugs with earthed (grounded)
power tools. Unmodified plugs and
matching outlets will reduce risk of electric
shock.
■Before connecting to the mains supply,
make sure that the voltage is the same
as that indicated on the rating plate of the
product or in this manual. Connecting the
product to any other power supply may
cause injury or damage.
■The manufacturer recommends you
connect to a power socket protected by an
RCD with a trip of 30 mA or less.
■Keep the ventilation openings clear of
debris and other accumulations to prevent

2
damage to the motor or possible fire.
■Keep the power cord away from heat, oil
and sharp edges.
■If the supply cord is damaged, it must be
replaced by the manufacturer, its service
agent or similarly qualified persons in order
to avoid a hazard.
■If you need to use an extension cord
ensure it is suitable for outdoor use and
has a current capacity rating sufficient to
supply your product. The extension cord
cable should be marked with either “H05
RN-F” or “H05 VVF”. Check it before every
use for damage; always uncoil it during
use because coiled cords can overheat.
Damaged extension cords should not be
repaired; they should be replaced with an
equivalent type.
■Make sure the power cord is positioned so
that it cannot be damaged by the cutting
means and will not be stepped on, tripped
over or otherwise subjected to damage or
stress.
■A power spike during motor start-up
causes voltage fluctuations which may
affect other electrical products in the same
power circuit. Connect the product to a
power supply with an impedance equal to
or less than 0.404 Ω to minimise voltage
fluctuations. Contact your electric power
supplier for further clarification.

checking if there is no blockage, connect the
power cord to the power supply and depress
the overload protection reset button. Press
the on switch to turn on the motor.
If the overload protection is activated and
there is no blockage, the overload may
have occurred when materials are fed into
the product too quickly for too long, causing
the motor to overheat. Allow the motor to
cool down. Empty the collection box before
restarting the product.
CLEARING A BLOCKAGE
WARNING
The blades are sharp and are likely to be hot.
Always wear heavy-duty protective gloves
when checking and clearing a blockage.

SHREDDING GUIDE
For best results when shredding, follow the
guidelines shown in the table below.
MATERIAL SHREDDING METHOD
Twigs and up to
6 mm diameter.
Feed into the feeding
chute at a rate which
the product will accept
without overloading. Use
the plunger provided to
push the material into
the chute if required.
Branches and
up to 45 mm in
diameter.
Clip off all side growth
with secateurs before
feeding into the feeding
chute. Use the plunger
provided to push the
material into the chute if
required.
Bedding plants,
weeds and
shrubby growth.
Knock soil and stones
off the roots to avoid
damage to the blades.
Freshly cut
foliage, hedge,
and kitchen
waste.(I.e.
cabbage
leaves,
vegetable
peelings etc.)
With any material having
a high moisture content
it is advised to feed
in some drier sticks
at regular intervals to
help push the material
through the cutting
assembly and prevent it
from clogging.
Dry sticks and
twigs
By inserting these at the
end of your shredding
task, this will help to
clean the moisture and
plant sap from the inside
of the product and the
cutting assembly.
■Do not allow garden waste to accumulate
before shredding as it will begin to compost,
become too damp and clog the cutting
assembly. Dry material will help most
material to clear the ejection chute. Save
some dry sticks until last to help clean the
blade area.
■Frequently monitor the build up/collection
of shredded material.
■The exit of the discharge chute must be
clear at all times to prevent blockages.
■When the collection box is full, turn the
product Off before emptying.
WARNING
Do not put your hands up inside the
shredder’s discharge chute to clear away
shredded material while the product is
switched on or connected to the mains
supply. The blades are sharp. Wear heavy-
duty gloves and exercise extreme caution
when cleaning and clearing blockages.
WARNING
When feeding long woody branches/stems
into the product be careful of whip and
vibrations as the materials get caught by
the cutter. The operator must wear eye
protection whenever using the product.
WARNING
The cutting device has a tendency to pull
branches/stems into the product. Do not
try to impede entry of the material being
cut once feeding has started. Always wear
gloves to prevent skin lacerations when
feeding material into the product.
NOTE: In normal use, do not switch off the
product until all of the shredded material has
cleared the cutter assembly. If the product is
switched off too quickly, remaining pieces of
material may clog the blade assembly and
stall the motor when the product is switched
back on.
