SHAVING PLATE ADJUSTMENT

■ The product performs at its best by following

these steps. Before use, always check that
the shaving plate is not in contact with the
blades. For optimal performance, keep a 1
mm gap between the shaving plate and the
blades.

■ If the product fails to shred material, the

shaving plate may need adjustment.

■ Over time, the shaving plate needs to be

adjusted to lessen its gap from the blades.
Ensure that the product is turned on and
working in normal forward direction. Adjusting
the shaving plate while the motor is turned off
could lead to serious damage to the product.

NOTE: Adjusting the shaving plate should
only be attempted when deemed totally
necessary. Adjusting the shaving plate too
often or too far could cause the product to
stop working.

■ While the product is running, turn the

adjusting knob clockwise.

■ When you hear metal on metal contact

or you see fine aluminum shavings in the
bottom of the collection container, stop the
adjustment and allow the product to run
for 30 seconds. After 30 seconds, turn the
adjustment knob counterclockwise until it is
no longer in contact with the shaving plate,
leaving a 1 mm gap.

NOTE: Complete any adjustment slowly to
avoid damaging the product. Overadjusting
the plate can cause serious damage to the
product.

BLADE SHARPENING

■ The product performs at its best by following

these steps. Before use, always check
that the blades are not in contact with the
shaving plate. For optimal performance,
keep a 1 mm gap between the blades and
the shaving plate.

■ If the product fails to shred material, the

blades may need to be sharpened.

■ Over time, the blades on the product

need to be sharpened. This can be
completed by adjusting the shaving plate
so that it will come into light contact with
the blades. Ensure that the product is
turned on and working in normal forward
direction. Adjusting the shaving plate
while the motor is turned off could
lead to serious damage to the product.
NOTE: Adjusting the shaving plate should
only be attempted when deemed totally
necessary. Adjusting the shaving plate too
often or too far could cause the product to
stop working.

■ While the product is running, turn the

adjusting knob clockwise.

■ When you hear metal on metal contact

or you see fine aluminum shavings in the
bottom of the collection container, stop
the adjustment and allow the product
to run for 30 seconds to sharpen the
blades. Once sharpening is complete, turn
the adjustment knob counterclockwise
until it is no longer in contact with the
shaving plate, leaving a 1 mm gap.
NOTE: Sharpening the blades requires
very light contact with the shaving plate.
Complete any adjustment slowly to avoid
damaging the product. Overadjusting the
plate can cause serious damage to the
product.

RISK REDUCTION

It has been reported that vibrations from
handheld tools may contribute to a condition
called Raynaud’s Syndrome. Symptoms may
include tingling, numbness, and blanching of

the ngers, usually apparent upon exposure

to cold. Hereditary factors, exposure to cold
and dampness, diet, smoking, and work
practices are all thought to contribute to the
development of these symptoms. There are
measures that can be taken bythe operator to
possibly reduce the effects of vibration:

■ Keep your body warm in cold weather.

When operating the product, wear gloves
to keep the hands and wrists warm. It is
reported that cold weather is a major factor
contributing to Raynaud’s Syndrome.

■ After each period of operation, exercise to

increase blood circulation.

■ Take frequent work breaks. Limit the

amount of exposure per day.

If you experience any of the symptoms of this
condition, immediately discontinue use and
see your physician.

WARNING

Injuries may be caused, or aggravated, by
prolonged use of a tool. When using any
tool for prolonged periods, ensure you take
regular breaks.

RESIDUAL RISK

Even when the product is used as prescribed,
it is still impossible to completely eliminate
certain residual risk factors. The following
hazards may arise during use and the
operator should pay special attention to avoid
the following:

■ injury caused by exposure to noise
– Wear hearing protection and limit

exposure.

■ injury caused by inhalation of dust and

SHREDDING GUIDE

For best results when shredding, follow the
guidelines shown in the table below.

MATERIAL SHREDDING METHOD

Twigs up to
6 mm diameter.

Feed into the feeding
chute at a rate which
the product will accept
without overloading.

Branches up
to 45 mm in
diameter.

Bedding plants,
weeds and
shrubby growth.

Dry sticks and
twigs

■ 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 bin is full, turn off the

product before emptying.

Do not put your hands up inside the
shredder’s discharge chute to clear away
shredded material while the product is
turned on or connected to the mains supply.
The blades are sharp. Wear heavy-duty
gloves and exercise extreme caution when
cleaning and clearing blockages.

When feeding long woody branches/stems
into the product be careful of whip and
vibrations as they get caught by the cutter.
The operator must wear eye protection
whenever using the product.

Clip off all side growth
with secateurs before
feeding into the feeding
chute.

Knock soil and stones
off the roots to avoid
damage to the blades.

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.

WARNING

WARNING

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 turn off the
product until all of the shredded material has
cleared the cutter assembly. If the product
is turned off too quickly, remaining pieces of
material may clog the blade assembly and
stall the motor when the product is turned
back on.
