Hints for optimum use
Start by trimming the top of the hedge. Slightly tilt the tool
(up to 15° relative to the line of cut) so that the blade tips
point slightly towards the hedge (fig. C1). This will cause
the blades to cut more effectively. Hold the tool at the
desired angle and move it steadily along the line of cut.
The double-sided blade allows you to cut in either direction.
In order to obtain a very straight cut, stretch a piece of
string along the length of the hedge at the desired height.
Use the string as a guideline, cutting just above it.
In order to obtain flat sides, cut upwards with the growth.
Younger stems move outwards when the blade cuts
downwards, causing shallow patches in the hedge (fig. C2).
Take care to avoid any foreign objects. Especially avoid
hard objects such as metal wire and railings, as these
could damage the blades.
Regularly oil the blades.
Guidelines for trimming (UK & Ireland)
Trim hedges and shrubs with seasonal leaves (new leaves
every year) in June and October.
Trim evergreens in April and August.
Trim conifers and other fast growing shrubs every six weeks
from May until October.
Guidelines for trimming (Australia & New Zealand)
Trim hedges and shrubs with seasonal leaves (new leaves
every year) in December and March.
Trim evergreens in September and February.
Trim conifers and other fast growing shrubs every six
weeks from October until March.
Your tool has been designed to operate over a long period of
time with a minimum of maintenance. Continuous satisfactory
operation depends upon proper tool care and regular cleaning.
Warning! Before performing any maintenance, switch off and
unplug the tool.
After use, carefully clean the blades. After cleaning, apply
a film of light machine oil to prevent the blades from rusting.
Regularly clean the ventilation slots in your tool using
a soft brush or dry cloth.
Regularly clean the motor housing using a damp cloth.
Do not use any abrasive or solvent-based cleaner.
Make sure all switches are free of debris before and after
Removing the guard (fig. A)
Warning! Remove the guard for servicing purposes only.
Always re-fit the guard after finishing servicing.
Loosen the screws (9) and remove them.
