User Manual Philips HR1377/90 Hand Blender

Yes, if you process hard ingredients such as bones or fruit with stones, this may damage your Philips hand blender.

The blade unit will not become blunt during normal use.
If the blade unit of your Philips hand blender is not performing as well as it used to, you can replace the whole blender bar.

No, you must not pour very hot ingredients into the blender jar as it may damage the jar and its accessories.

If you want to pour ingredients, like boiled spinach for pureeing, into the jar, first let the ingredients cool down to a temperature of less than 80°C / 175°F to avoid damaging the appliance.

Yes, but only with the XL chopper and the serrated blade (HR1372, HR1374, HR1378).

Do not crush ice with the hand blender or the normal chopper blade, as you could damage the blades.
