trimming hedges, shrubs and brambles. This tool is intended
for consumer use only.
Safety instructions
Warning! When using mains-powered tools, basic safety
precautions, including the following, should always be
followed to reduce the risk of fire, electric shock, personal
injury and material damage.
Read all of this manual carefully before operating the tool.
Retain this manual for future reference.
Remove the plug from the socket before carrying out any
adjustment, servicing or maintenance.
Keep work area clean
Cluttered areas and benches can cause accidents.
Consider work area environment
Do not expose the tool to rain. Do not use the tool in damp or
wet conditions. Keep the work area well lit. Do not use the
tool where there is a risk of causing fire or explosion, e.g. in
the presence of flammable liquids and gases.
Keep children away
Do not allow children, visitors or animals to come near the
work area or to touch the tool or mains cable.
Dress properly
Do not wear loose clothing or jewellery, as these can be
caught in moving parts. Preferably wear rubber gloves and
non-slip footwear when working outdoors. Wear protective
hair covering to keep long hair out of the way.
Personal protection
Always use safety glasses. Use a face or dust mask whenever
the operations may produce dust or flying particles.
Hearing protection should be worn.
Guard against electric shock
Prevent body contact with earthed or grounded surfaces
(e.g. pipes, radiators, cookers and refrigerators).
Electric safety can be further improved by using a
high-sensitivity (30 mA / 30 mS) residual current device (RCD).
Do not overreach
Keep proper footing and balance at all times.
Stay alert
Watch what you are doing. Use common sense.
Do not operate the tool when you are tired.
Secure workpiece
Use clamps or a vice to hold the workpiece. It is safer and it
frees both hands to operate the tool.
Connect dust extraction equipment
If devices are provided for the connection of dust extraction
and collection facilities, ensure that these are connected and
properly used.
Remove adjusting keys and wrenches
Always check that adjusting keys and wrenches are removed
from the tool before operating the tool.
Extension cables
Before use, inspect the extension cable and replace if damaged.
When using the tool outdoors, only use extension cables
intended for outdoor use. Up to 30 m of Black & Decker
extension cable can be used without loss of power.
Use appropriate tool
The intended use is described in this instruction manual.
Do not force small tools or attachments to do the job of a
heavy-duty tool. The tool will do the job better and safer at the
rate for which it was intended. Do not force the tool. Do not
use the tool for purposes not intended, for example, do not
use a circular saw to cut tree limbs or logs.
Warning! The use of any accessory or attachment or
performance of any operation with this tool other than those
recommended in this instruction manual may present a risk of
personal injury.
Check for damaged parts
Before use, carefully check the tool and mains cable for
damage. Check for misalignment and seizure of moving parts,
breakage of parts, damage to guards and switches and any
other conditions that may affect its operation. Ensure that the
tool will operate properly and perform its intended function.
Do not use the tool if any part is damaged or defective. Do not
use the tool if the switch does not turn it on and off. Have any
damaged or defective parts repaired or replaced by an
authorised repair agent. Never attempt any repairs yourself.
Unplug the tool
Unplug the tool when it is not in use, before changing any parts
of the tool, accessories or attachments and before servicing.
Avoid unintentional starting
Do not carry the tool with a finger on the on/off switch.
Be sure that the tool is switched off when plugging in.
Do not abuse cord
Never carry the tool by its cord or pull it to disconnect from the
socket. Keep the cord away from heat, oil and sharp edges.
Store idle tools
When not in use, tools should be stored in a dry, locked up or
high place, out of reach of children.
Maintain tools with care
Keep cutting tools sharp and clean for better and safer
performance. Follow the instructions for maintenance and
changing accessories. Keep handles and switches dry,
clean and free from oil and grease.
This tool complies with relevant safety requirements.
Repairs should only be carried out by qualified persons using
original spare parts; otherwise this may result in considerable
danger to the user.
Electrical safety
This tool is double insulated; therefore no earth wire
is required. Always check that the power supply
corresponds to the voltage on the rating plate.

◆ Trim evergreens in April and August.
◆ Trim conifers and other fast growing shrubs every six
weeks from May until October.
Guidelines for trimming (Australia & New Zealand)

Your tool has been designed to operate over a long period of
time with a minimum of maintenance. Continuous satisfactory
operation depends upon proper tool care and regular cleaning.
Warning! Before performing any maintenance, switch off and
unplug the tool.
Warning! Never attempt to lock a switch in the on position.
Hints for optimum use
◆ Start by trimming the top of the hedge. Slightly tilt the
tool (up to 15° relative to the line of cut) so that the blade
tips point slightly towards the hedge (fig. C1 & C3).
This will cause the blades to cut more effectively.
Hold the tool at the desired angle and move it steadily
along the line of cut. The double-sided blade allows you
to cut in either direction.
◆ In order to obtain a very straight cut, stretch a piece of
string along the length of the hedge at the desired height.
Use the string as a guideline, cutting just above it.
◆ In order to obtain flat sides, cut upwards with the growth.
Younger stems move outwards when the blade cuts
downwards, causing shallow patches in the hedge.
◆ With the handle in the forward position the tool can be
used to cut the high sides of the hedge. Move the tool
side to side in a 40° arc (fig. C2).
◆ Take care to avoid any foreign objects. Especially avoid
hard objects such as metal wire and railings, as these
could damage the blades.
Regularly oil the blades.
After use, carefully clean the blades. After cleaning,
apply a film of light machine oil to prevent the blades
from rusting.
Regularly clean the ventilation slots in your tool using a
soft brush or dry cloth.
Regularly clean the motor housing using a damp cloth.
Do not use any abrasive or solvent-based cleaner.
Make sure all the handle release buttons and switches
are free of debris before and after use.
Always store the tool with the handle locked in the
forward position.

◆ Safely dispose of the old plug.
