objects that can be projected or get caught during
the cutting.
Using pruning shears, first prune out branches of a
n
diameter greater than 27 mm.
Young buds can be trimmed easily with a scythe
n
movement; older and bigger hedges can be trimmed
easily with a sawing movement.
If desired. You can use a string to help cut your
n
hedge level. Decide how high you want the hedge.
Then ,stretch a piece of string along the hedge at this
height. Trim the hedge just above this guide line of
string. See Figure 4.Trim the side of a hedge so that it
will be slightly narrower at the top. See Figure 5.More
of the hedge will be exposed when shaped this way,
and it will be more uniform.
If hard objects become jammed in the cutter blade,
n
switch off the tool immediately, pull out plug first and
only then remove the objects.
Metal objects such as wire fences and plant supports
n
can damage the blade. Do not let the cutting blades
come in contact with materials that can not be
trimmed, such as stones or metal.
Always lay the lead away from the working area.
n
Always work away from the power socket. For
this reason, decide on the direction of cut before
beginning work.
