1. in domestic gardens and allotments.
   It must not be used in public places, parks, sport arenas, or in agriculture or forestry.
   Compliance with the operating instructions provided by the manufacturer is a prerequisite for using the Backpack Sprayer correctly.
2. In accordance with the laws governing the use of pesticides and detergents, only authorised substances may be used (authorised specialist shop).

Caution !

Due of the risk of physical injury, the GARDENA Backpack Sprayer must not be used for spraying substances other than those specified by GARDENA. Do not use your Backpack Sprayer for spraying acids, disinfectants or waterproofing agents.

We recommend that you only use pesticides approved by the BBA (German Federal Biological Research Centre for Agriculture and Forestry). To our knowledge at the time of manufacturing the Backpack Sprayer, the pesticides approved by the BBA will not damage the materials used to construct the Backpack Sprayer.

When spraying insecticides, herbicides and fungicides or other liquid plant protection products, you must comply with all special precautionary measures specified by the manufacturer of the product you are using.

For Your Safety

Danger of physical injuries:
➝ Never open the Backpack Sprayer or unscrew the sprayer handle when the Backpack Sprayer is still pressurised.
➝ Always release the pressure completely before opening the Backpack Sprayer by pressing the pushbutton of the sprayer handle.

Cleaning :
➜ After using your Backpack Sprayer, always release the pressure then empty, carefully clean and rinse the tank in clean water. Leave the Backpack Sprayer open and allow it to dry (see 5. Maintenance).
➜ Always clean the Backpack Sprayer before using a different product to avoid chemical reactions.
➜ To prevent reactions with the products you are using, never use aggressive cleaning agents that contain solvent or petrol.

Operation:
 ➜ Check the Backpack Sprayer for possible damages before each use.
