Hedge Trimmer
Maintaining the blades
WARNING: Wear sturdy, cut-resistant gloves at all times when handling the blades.
• Remove any deposits with a brush after every use, and apply a light film of lubricant spray to
the blade
• Periodically check the blades for sharpness and inspect for damage
• The blade teeth can be sharpened using a flat file. Sharpen the cutting edges only, see Image N
Note: If you are unsure about how to sharpen the blades, have the hedge trimmer
sharpened by a professional.
• If there is significant blade damage, have the blades replaced by an authorised GMC service
centre
GB
Removing a blockage in the blades
• Do not force the blockage out at a different angle to the blade. Instead carefully slide out in line
with the blade to prevent damage. See Image M for a typical blockage. The blockage must be
removed at exactly the same angle that it entered the blade. It is important the flatness between
the two blades is maintained for normal operation, which may become damaged if the blockage
is incorrectly removed
Abnormal vibration and noise
• If there is any abnormal vibration and noise it is possible some screws may be working loose.
Re-tighten the screws shown in Images O & P.
