General Safety Rules
SAVE THESE INSTRUCTIONS
WARNING! Read all instructions Failure to follow all
instructions listed below may result in electric shock, fire
and/or serious injury. The term “power tool” in all of the
warnings listed below refers to your mains-operated
(corded) power tool or battery-operated (cordless) power
tool.
1) Work area
a) Keep work area clean and well lit. Cluttered and
dark areas invite accidents.
b) Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases or dust. Power tools
create sparks which may ignite the dust or fumes.
c) Keep children and bystanders away while
operating a power tool. Distractions can cause you
to lose control.
2) Electrical safety
a) Power tool 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
b) Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric
shock if your body is earthed or grounded.
c) Do not expose power tools to rain or wet
conditions. Water entering a power tool will increase
the risk of electric shock.
d) Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges or
moving parts. Damaged or entangled cords
increase the risk of electric shock.
e) When operating a power tool outdoors, use an
extension cord suitable for outdoor use. Use of a
cord suitable for outdoor use reduces the risk of
electric shock.
3) Personal safety
a) Stay alert, watch what you are doing and use
common sense when operating a power tool. Do
not use a power tool while you are tired or under
the influence of drugs, alcohol or medication. A
moment of inattention while operating power tools
may result in serious personal injury.
b) Use safety equipment. Always wear eye
protection.Safety equipment such as dust mask,
non-skid safety shoes, hard hat, or hearing
protection used for appropriate conditions will reduce
personal injuries.
c) Avoid accidental starting. Ensure the switch is in
the off-position before plugging in.Carrying
power tools with your finger on the switch or
plugging in power tools that have the switch on
invites accidents.
d) Remove any adjusting key or wrench before
turning the power tool on. A wrench or a key left
attached to a rotating part of the power tool may result
in personal injury.
e) Do not overreach. Keep proper footing and
balance at all times. This enables better control of
the power tool in unexpected situations.
f ) Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing and gloves
awayfrom moving parts. Loose clothes, jewellery
or long hair can be caught in moving parts.
g) If devices are provided for the connection of
dust extraction and collection facilities, ensure
these are connected and properly used. Use of
these devices can reduce dust-related hazards.
4) Power tool use and care
a) Do not force the power tool. Use the correct
power tool for your application. The correct power
tool will do the job better and safer at the rate for
which it was designed.
b) Do not use the power tool if the switch does not
turn it on and off. Any power tool that cannot be
controlled with the switch is dangerous and must be
repaired.
c) Disconnect the plug from the power source
before making any adjustments, changing
accessories, or storing power tools. Such
preventive safety measures reduce the risk of
starting the power tool accidentally.
d) Store idle power tools out of the reach of children
and do not allow persons unfamiliar with the
power tool or these instructions to operate the
power tool. Power tools are dangerous in the hands
of untrained users.
e) Maintain power tools. Check for misalignment or
binding of moving parts, breakage of parts and
any other condition that may affect the power
tools operation. If damaged, have the power tool
repaired before use. Many accidents are caused by
poorly maintained power tools.
f ) Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control.
g) Use the power tool, accessories and tool bits
etc., in accordance with these instructions and in
the manner intended for the particular type of
power tool, taking into account the working
conditions and the work to be performed. Use of
the power tool for operations different from intended
could result in a hazardous situation.
5) Service
a) Have your power tool serviced by a qualified
repair person using only identical replacement
parts. This will ensure that the safety of the power tool
is maintained.

THE APPLIANCE IS SWITCHED OFF AND UNPLUGGED.
Push the upper (3) and lower (5) handle in the direction of
an arrow to upright positon.
OPERATION
CABLE CLEAT
The power supply cable should be inserted and looped
around the Cable cleat, this will remove any strain being
placed on the Switch control unit.
NOTE: The blade continues to rotate for a few seconds
after the machine is switched off. Allow the motor/blade to
stop rotating before switching “on” again. Do not rapidly
switch off and on.
STARTING AND STOPPING (Fig. 4, 5)
Starting:
1. Set the mower to the required ‘cutting height’.
2. Press the safety button (2).
3. Squeeze the switch lever (1) towards the handle.
4. Release the safety button.
Stopping:
Release the switch lever.
WARNING! When mowing do not allow the motor to labour
particularly in heavy conditions. When the motor labours the
speed of the motor drops and you will hear a change in the
motor sound, when this occurs stop mowing, release the
switch lever and raise the height of cut. Failure to do so
could damage the machine.
MOWING
Place the lawnmower on the edge of the lawn, as close to
the power point as possible. Work away from the power
point.
Position the cable to opposite side (already cut) at the end
of each turn.
1. Areas of heavy growth should be mown without collecting
the clippings.
2. If collection is required, firstly mow the area using the
maximum cutting height setting, without the grass collection
bag attached.
3. Allow the clippings to dry out.
4. Attach the grass collection bag and mow the area, again
using the maximum cutting height setting.
5. Progressively lower the cutting height setting and mow the
area again until the required finish is obtained.
NOTE! To prevent damage to the grass, do not remove
more than one third of the grass’s height on any one cut.
NOTE! When the blade becomes jammed or if the motor is
overloaded, remove the plug from the power supply.
Clear any obstruction and wait for a few minutes before
continuing to use the mower.
