HS 45 Petrol Hedge Trimmer

Light and compact hedge trimmer with a choice of blade length

Overview

The HS 45 petrol hedge trimmer is the ideal tool for light maintenance of hedges, shrubs and bushes in your garden.

This neat tool is available with a 45 cm or 60 cm bar with double-sided blades and built-in cut protection. It also features our anti-vibration system, which reduces vibrations at the handle of the machine and makes it much more comfortable to use.

The long-life air filter system means you can leave it longer between cleaning and gives better protection of the engine. The manual fuel pump means that the hedge trimmer is easier to start too, with less pulls of the starter cord needed to get the HS 45 going. It features our 2-MIX engine, which is powerful but economical too.

The HS 45 is our best-selling hedge trimmer as it's durable, reliable and a great option for use in your garden.

  • Anti-vibration system Zoom
    Anti-vibration system

    Intense vibration at the handles of power tools can lead to long-term effects on blood vessels in the hands and arms. STIHL has therefore developed an effective anti-vibration system whereby the oscillations from the machine's engine are dampened which significantly reduces vibrations at the handles.

    • Service Kit 46 Zoom
      NEWService Kit 46

      With Service Kit 46 for STIHL petrol hedge trimmers you can carry out simple maintenance work on your hedge trimmer yourself. Regular standard maintenance, such as replacing the air and fuel filters and the spark plug, increases the service life of your hedge trimmer. And because of this, you yourself can help to ensure that machine components and parts are protected from dirt and damage so your hedge trimmer always works reliably and with optimum performance.

      Service Kit 46 for the HS 45 (2-MIX, post 2013) includes the following components for standard maintenance:

      • Fleece air filter
      • Spark plug
      • Fuel filter

      The STIHL fleece filter offers good filter quality under different operating conditions. Coarse dirt particles are caught on the surface, while the fine dirt particles are retained inside the filter. In this way, the motor of your hedge trimmer is reliably protected against the ingress of abrasive dust. The performance is retained, the consumption is low and you can continue to start your machine with ease. The fuel filter ensures that no foreign particles get into the engine via the fuel. Regular replacement protects the motor and supports a long service life. In order to maintain performance, it is also recommended to regularly replace the spark plug for continued clean combustion in the engine.

      For the maintenance of the air filter and spark plug, it is best to use the practical combination wrench that you received with your STIHL hedge trimmer. A cardboard hook is integrated in the packaging box of the service kit. This allows you to easily remove and replace the fuel filter. You do not need any additional tools.
