ASSEMBLY
Warning! Remove the battery pack before cleaning or maintaining the tool, fitting the
edger wheel or plant guard or before making any adjustments to the tool, especially around the string
head.
Remove battery pack before transporting or storing the tool

and injury to the operator may occur. The guard is not fitted to the trimmer when it is delivered to you to

Rewinding the spool
The spool is supplied with the line pre-wound. The twisted line is 1.65mm (0.065”) in diameter, which
gives good cutting performance and reduced noise. Follow the instructions below to rewind new line onto
the spool.
To remove the string head, press and hold the shaft lock button and unscrew the head anti-clockwise.
Component parts of the string head
Cut a piece of nylon line 1.65mm (0.065”) in diameter maximum 12m long (you may find it easier to
practice with a shorter line length at first). Find the centre of the line and loop it onto the notch in the
centre flange of the spool. Wind the line around the spool, in the direction indicated by the arrow on the
spool, keeping each end of the line in its own channel. Keep the line tight as you wind so that the line
coils smoothly onto the spool
Wrap the line around the spool leaving about 20cm line exposed on each side
Keep the line tight and clip the lines into the notches in the bottom flange of the spool to hold the line in
place while you fit the spool into the housing.
The smaller end of the spring goes into the top of the spool
Then put the spool and spring into the housing leaving the ends of the line protruding from the cut outs on
each side.
Thread the string guides onto the line as shown
Slide into place. Do the same on both sides.
Position the cover in place as shown and press the cover onto the housing until the clips snap into place.
Pull on both ends of the line to free them from the notches in the spool.
To replace the spool, press on the spool lock button and screw the head clockwise onto the shaft and
hand tighten.

Adjusting the line length – Bump feed head
During use, the line will become worn, or may break off if it strikes a stone or a similar hard object. To
increase the length of the line, switch on the trimmer and while it is running tap the head of the trimmer
against the ground. When the orange button on the trimmer head is bumped against the ground,
centrifugal force will extend the line. Excess line will be cut off by the cutting blade built into the ground.
Height adjustable handle
The auxiliary handle (5) is height adjustable. To move the handle, first release the orange handle clamp
on the underside of the handle. Slide the handle to the desired height and clamp in position
Setting the trimmer head angle
The angle of trimmer head can be set to different working positions.
Press the “PUSH” button with one hand and rotate the trimmer head to the required position. Release the
“PUSH” button and the head will lock into place. There are 5 preset lock positions
