HEDGE TRIMMING TECHNIQUES

Trim sides of a hedge first, and then the top.

Vertical cut:

• With the single-sided blade hedge-trimmer, model HT2301 always cut from the bottom up (OP8). With the 2-sided blade model CHT2301 use an arcing cut from the bottom upwards, then downwards to use both sides of the blades (OP9).

Horizontal cut:

• In order to get the best cutting results, slightly tilt the blade (5÷10°) towards the cutting direction (OP10, OP11). Cut slowly, specially with thick hedges.

Always follow the safety precautions. The hedge-trimmer must only be used to trim hedges or small bushes. It is forbidden to cut other types of material. Do not use the hedgetrimmer as a lever to lift, move or break objects, nor lock it on fixed supports. It is forbidden to apply tools or applications that are not the ones indicated by the manufacturer onto the hedge-trimmer’s power take-off. Do not use it for pruning trees or cutting grass.
