INTRODUCTION
INTRODUCTION

• Do not spray or wet the appliance with water.
.
• Do not use detergents or solvents as these could
ruin the trimmer. The parts in plastic can easily be
damaged by chemical agents.
.
• If the line cutting blade no longer cuts or breaks,
have this replaced by contacting your local Osaki
agent.
CAUTION! The blade can give deep cuts.
For repairs which have not been explained in these
instructions, contact your local Osaki agent.
TROUBLE-SHOOTING
CAUTION! Before every operation, disconnect
the electric power supply.
• If the grass trimmer vibrates: remove the spool
and clean its slot carefully removing any grass and
debris. In the event of the problem not disappearing,
have the trimmer checked at your local Osaki agent.
• If the grass trimmer does not start: check all
the electrical connections make sure the safely
circuit-breaker has not been activated: check that
no fuse has blown in your electrical system.
If after the above checks, the grass trimmer still does
not start, have it checked by your local Osaki agent.
• Cut the grass by moving the grass trimmer
from right to left and proceed slowly keeping the
trimmer inclined by about 30° (See fig.6).
.
• Before starting work, make sure that the area
to be cut is free of stones, debris, wires and any
other objects.
.
• High grass should be cut in layers, always
beginning from the top. The cuts should be
short (See fig.5).
.
• Do not cut damp or wet grass. Dry grass will
give excellent results.
.
• Always let the nylon line rotate at top speed,
do not work in such a way as to overload the
trimmer. Caution! Do not use the grass trimmer
without the guard.
.
• Never pass the grass trimmer over the extension
cable while the grass trimmer is running; make sure
it is always in a safe position behind your back.
MAINTENANCE
Before carrying out any maintenance operations,
switch off the electric power supply by disconnecting
the plug from the extension cable.
• Regular cleaning and maintenance of your grass
trimmer will ensure efficiency and prolong the life
of the trimmer.
.
• After each cutting operation, take apart and
clean out the grass and soil from the spool and its
slot, the whole trimmer and in particular the guard
ensuring to turn off the power supply and disconnect
the power plugs.
.
• During operation, keep the air slots clean and
free of grass.
.
• Only use a cloth soaked with hot water and a
soft brush to clean the grass trimmer.
.
MAINTENANCE
spool on the ground. This will release more cutting
line which will be cut to the correct length by the
blade fitted in the cutting head guard (See fig.3).
REPLACEMENT OF THE SPOOL AND LINE (See fig.4).
• Switch off at the wall socket and remove the plug.
Turn the trimmer upside down with the guard facing
upwards.
.
• Hold firmly with one hand the spool hub (1)
and with the other hand hold the spool retainer (2),
depress the ribbed sections of the spool retainer
from both sides and remove from the spool hub.
.
• Remove the empty spool (3) and clean
the inside of the spool hub and retainer carefully
removing all ground and grass residue.
.
• Insert the new spool and line into the spool retainer
and push the ends of the line through the lateral
holes provided in the spool retainer.
.
• Place the spool retainer with spool into the spool
hub by pushing down and securing into position.
Re-establish the length of the line by pushing the
head of the spool and line and pulling the line ends
out to the desired length.
CAUTION! Under no circumstances wind extra line
on the empty spool but instead replace it with a new
one, the same as the original. The use of line with
different characteristics to those of the original can
permanently damage the grass trimmer as well as
invalidating the terms of the guarantee.
OPERATION
Inspect the area to be cut before starting. Remove
any objects or debris that could be thrown, jammed
or become entangled in the cutting line.
• Start off slowly, when you have gained experience,
you will be able to use the grass trimmer to its full
potential.
• Start the grass trimmer before getting close to the
grass to be cut.
ASSEMBLY
The grass trimmer is supplied with some com-
ponents not assembled. To assemble these pro-
ceed as follows:
MOUNTING THE GUARD (See fig.2)
• Align the reference indications of the body (2) of
the spool holder (3) and of the guard (4). Insert the
guard in the body (up to the collar) and rotate it in
the direction indicated by the arrow on the guard
(5) until the hole of the guard corresponds to that
of the body. Hold in place with screws supplied (1).
CAUTION! During this operation beware of the line
trimming blade. Caution! Never use the grass trimmer
without the guard. It is vital for your and other persons
safety and for the good working order of the trimmer.
The failure to observe these safety regulations is not
only dangerous but also invalidates the guarantee
terms.
STARTING
Insert the plug into the extension cable and attach it
to the handle (See fig.1).
If the trimmer is to be used for the first time,
check that the nylon line touches or passes over the
metal blade attached to the shield.
NOTE: The metal blade attached to the shield will cut
the line to the proper length.
Only approach the implement to the grass to be cut
while it is in operation, i.e. while the switch is pressed
down. To cut long grass, make several small cuts.
Never cut wet or very damp grass. The line should
be protected against premature wear caused by hard
obstacles. For this purpose keep the trimmer away
from hard surfaces using the guard's edge as a protec-
tion. A short or worn line will reduce cutting capacity.
CUTTING LINE ADJUSTMENT
As the grass trimmer is used the cutting line will
become worn down and less efficient. To increase
the length of the cutting line with the Grass Trimmer
running, bump the centre button in the cutting line
OPERATION

• Do not spray or wet the appliance with water.
.
• Do not use detergents or solvents as these could
ruin the trimmer. The parts in plastic can easily be
damaged by chemical agents.
.
• If the line cutting blade no longer cuts or breaks,
have this replaced by contacting your local Osaki
agent.
CAUTION! The blade can give deep cuts.
For repairs which have not been explained in these
instructions, contact your local Osaki agent.
TROUBLE-SHOOTING
CAUTION! Before every operation, disconnect
the electric power supply.
• If the grass trimmer vibrates: remove the spool
and clean its slot carefully removing any grass and
debris. In the event of the problem not disappearing,
have the trimmer checked at your local Osaki agent.
• If the grass trimmer does not start: check all
the electrical connections make sure the safely
circuit-breaker has not been activated: check that
no fuse has blown in your electrical system.
If after the above checks, the grass trimmer still does
not start, have it checked by your local Osaki agent.
• Cut the grass by moving the grass trimmer
from right to left and proceed slowly keeping the
trimmer inclined by about 30° (See fig.6).
.
• Before starting work, make sure that the area
to be cut is free of stones, debris, wires and any
other objects.
.
• High grass should be cut in layers, always
beginning from the top. The cuts should be
short (See fig.5).
.
• Do not cut damp or wet grass. Dry grass will
give excellent results.
.
• Always let the nylon line rotate at top speed,
do not work in such a way as to overload the
trimmer. Caution! Do not use the grass trimmer
without the guard.
.
• Never pass the grass trimmer over the extension
cable while the grass trimmer is running; make sure
it is always in a safe position behind your back.
MAINTENANCE
Before carrying out any maintenance operations,
switch off the electric power supply by disconnecting
the plug from the extension cable.
• Regular cleaning and maintenance of your grass
trimmer will ensure efficiency and prolong the life
of the trimmer.
.
• After each cutting operation, take apart and
clean out the grass and soil from the spool and its
slot, the whole trimmer and in particular the guard
ensuring to turn off the power supply and disconnect
the power plugs.
.
• During operation, keep the air slots clean and
free of grass.
.
• Only use a cloth soaked with hot water and a
soft brush to clean the grass trimmer.
.
MAINTENANCE
spool on the ground. This will release more cutting
line which will be cut to the correct length by the
blade fitted in the cutting head guard (See fig.3).
REPLACEMENT OF THE SPOOL AND LINE (See fig.4).
• Switch off at the wall socket and remove the plug.
Turn the trimmer upside down with the guard facing
upwards.
.
• Hold firmly with one hand the spool hub (1)
and with the other hand hold the spool retainer (2),
depress the ribbed sections of the spool retainer
from both sides and remove from the spool hub.
.
• Remove the empty spool (3) and clean
the inside of the spool hub and retainer carefully
removing all ground and grass residue.
.
• Insert the new spool and line into the spool retainer
and push the ends of the line through the lateral
holes provided in the spool retainer.
.
• Place the spool retainer with spool into the spool
hub by pushing down and securing into position.
Re-establish the length of the line by pushing the
head of the spool and line and pulling the line ends
out to the desired length.
CAUTION! Under no circumstances wind extra line
on the empty spool but instead replace it with a new
one, the same as the original. The use of line with
different characteristics to those of the original can
permanently damage the grass trimmer as well as
invalidating the terms of the guarantee.
OPERATION
Inspect the area to be cut before starting. Remove
any objects or debris that could be thrown, jammed
or become entangled in the cutting line.
• Start off slowly, when you have gained experience,
you will be able to use the grass trimmer to its full
potential.
• Start the grass trimmer before getting close to the
grass to be cut.
ASSEMBLY
The grass trimmer is supplied with some com-
ponents not assembled. To assemble these pro-
ceed as follows:
MOUNTING THE GUARD (See fig.2)
• Align the reference indications of the body (2) of
the spool holder (3) and of the guard (4). Insert the
guard in the body (up to the collar) and rotate it in
the direction indicated by the arrow on the guard
(5) until the hole of the guard corresponds to that
of the body. Hold in place with screws supplied (1).

STORAGE
Follow these recommendations when storing the
grass trimmer:
• Clean all the grass trimmer, this prevents mould
from forming.
• Store it out of the reach of children, in a stable
and safe position and in dry place where the
temperature is not too hot or too cold.
