Bosch Hedge Trimmer Repair Guide – 5 Steps Guide

Several Bosch hedge trimmers have been awarded good or very good marks by Stiftung Warentest. In addition to the solid construction, Stiftung Warentest also rates the manufacturer’s repair and spare parts service as exemplary. Nevertheless, even a robust Bosch hedge trimmer can break.

In this article, you’ll learn what you can do yourself and when it’s better to call in the Bosch online repair service.

What problems can you fix yourself?


Basically, you can fix all problems caused by dust or dirt yourself. You can also replace wear parts yourself, provided you use genuine Bosch spare parts or Bosch accessories.

Problems that you can solve yourself include, for example:

  • Cleaning and sanitizing the appliance
  • Replacing loose screws
  • Sharpen knife blades
  • Lubricating blades and gears


It is better to leave the repair of the motor, electronic parts or power cord to the trained personnel from the Bosch Service Center.

Bosch hedge trimmer repair – explained step by step

  1. tools and required material
    A workbench or a sufficiently large table is best suited for working. Provide one or more containers for small parts.

For repairing and cleaning you need:

  • Screwdriver
  • Cleaning cloth
  • Wire brush with soft bristles
  • Oil and/or gear grease
  • Cleaning agent to remove resin
  1. safety
    In any case, make sure that the Bosch hedge trimmer does not start suddenly. To do this, either remove the battery, unplug the power cord or, in the case of a gasoline engine, remove the spark plugs. When working on the blade, be sure to wear protective gloves. 3.
  2. open the housing
    Place the hedge trimmer with the bottom side up and fix it so that it cannot slip away. Use a screwdriver with a suitable blade and size.

If screws are rusted, use solvent to remove the rust. Do not use force to loosen stuck screws!

When disassembling, it is essential to remember the sequence!

  1. clean or replace parts
    Clean dirty parts as good as possible. All metal parts, including screws, can be oiled.

Take the opportunity to replace rusted or worn out screws. Be sure to use the appropriate size.

  1. reassemble the Bosch hedge trimmer.
    Proceed in reverse order. Make sure washers and gaskets are reinstalled and all screws are tight. After the repair or maintenance is complete, start the hedge trimmer for a short test run.

Common hedge trimmer malfunctions and their possible causes


The motor does not run


The problem occurs with electric and battery hedge trimmers. Either the extension or power cord is defective or the internal fuse in the unit. The problem could also be with the stop/start switch.

Loud noises occur during cutting


This could be either because the hedge trimmer is dirty or because screws or other parts are loose.

The cutting teeth move slowly


This problem indicates that the blade is dirty. It should be cleaned after each use.

The blade stops


This is because it is jamming. When a branch is too thick, a safety device makes the hedge trimmer stop to prevent overloading and damaging the motor. On some models, the engine may also shut down if it overheats. Once the blockage is removed or the motor cools down, the damage should be repaired.

Can you sharpen the cutting blades yourself?


In principle, this is possible, but it requires some effort and skill. You have to disassemble the blade.

This opportunity can be used immediately excellent to thoroughly clean the blades and then lubricate them. The tools you need are a file, a tray or fixation for the blades, a dry cloth and cleaning and care products.
