• 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.

.

have this replaced by contacting your local Osaki 

agent.
