the knob again. See Dia 6.
Preparing the trimmer for use
1. Adjust the main shaft to the correct
working length for your physical size. To
do this, turn the height adjustment
locking mechanism clockwise to unlock
and pull/push the lower shaft to the
desired length. Turn the locking
mechanism anti-clockwise till the shaft
is firmly locked. See Dia 7
2. Check the length of the nylon cutting
line, pull line to inner edge of outer
guard, if the line is very short, i.e. more
than 50mm away from edge of guard,
push down on centre of cutting head
and at the same time pull the line a few
centimeters beyond the guard (see Dia
8 ), when the trimmer starts the line will
automatically be cut to the correct
length.
3. When you need to increase the line
length during use you can simply 'bump
feed' the trimmer to restore line to
correct length. To bump feed, turn on
the trimmer and gently bump the top of
the cutting head on a firm surface, the
line will be automatically extended and
cut, see Dia 9
OPERATING THE TRIMMER
1. To switch on the trimmer, press the
safety switch, then close upon the
On/Off switch. Release the On/Off
switch to stop, see dia 10.
2. If you find that the nylon line is too short
follow the instruction as in 'Preparing the
trimmer for use' section 4 (dia 8)
lLet the trimmer run for a few seconds
without touching the working area, and
allow the trimmer to cut the line.
lUse the trimmer at an angle of
approximately 20 degree to the working
area, see Dia 11.
lSwing the trimmer from side to side, see
Dia 12.

small 'bits' this will keep machine
operating at high speed and will greatly
improve cutting efficiency, see dia13
and dia14.

when using near fences walls etc, and
move in a backwards direction, this will
save damage, see Dia 15 and Dia 16.
REPLACING THE CUTTING LINE
Warning! Always remove the battery
pack before carrying out any

TROUBLE SHOOTING
Although your new cordless grass trimmer
is really easy to operate. If you do
experience problems, check the following:
If grass trimmer will not operate
lCheck battery pack assembly
lCharge the battery: running of the grass
trimmer is dependent upon sufficient
charge in the battery pack. The battery
charge will deplete if not used for a long
period of time. Try recharging the
battery pack. Ensure that the battery
pack is fully contacted charger base.
Note: The battery pack will only fit into the
charger with + to + and - to -. The charger
will not operate at extremes of temperature.
The charger will get warm during charging
but this is normal.
If the battery will not charge
Check to see if the battery is properly
inserted the charger base, and make sure
the indicator light is on, if not check the
mains supply.
If the trimmer is not cutting properly
Check the condition of the cutting head, if
the cutting line is too short or cutting head
damaged. Note: do not use damaged
cutting head.

If battery pack leaks
A small amount of leakage may occur at
extremes of temperature or after heavy
use. Wash off any leakage from hands,
skin or clothes immediately with soap and
water.
If a fault is suspected return the
trimmer to an authorized dealer for
repair.
Note: There are no user serviceable parts
in the trimmer.
FREQUENTLY ASKED QUESTIONS
The grass trimmer body grows hot
following extensive uses
Under normal load condition the body
trigger and battery pack will heat up as the
energy absorbed in the drilling operation
produced heat. Gears, motor and electrical
energy are responsible. This is quite
normal. Simply allow the grass trimmer to
cool down for 5mins.
The battery pack gets warm during use
The power-draw from the battery
generates heat. this is increased as the
energy draw increases. you will not
damage the battery pack and the
generated heat is normal. Should you
desire, simply allow the grass trimmer to
cool off to prior to continuing work.
The battery pack gets warm when
charging
This is normal. It is a result of the chemical
reaction inside the batteries during the
charging process. The charging process is
a energy translation process, the electric
power will partly transform into chemical
power, meanwhile, partly transform into
heat. But this will not damage the battery
pack.

lA 3 hours charging enables the grass trimmer to operate at
full power.
lFurther charging to a maximum of 5 hours increases the use
time.
YOUR BATTERY REQUIRES CHARGING
PRIOR TO USE
lContinuous charging can damage the battery cells.
lYour grass trimmer should only be re-charged when it begins
to run slowly
DO NOT LEAVE YOUR TRIMMER ON
CHARGE CONTINUALLY
