How long can I run my hand blender for?

It is important that the motor unit is only run for 1 minute, no longer, in any 4 minute period, particularly for heavy mixtures.
In the unlikely event you need to use the hand blender for longer ensure it is allowed to rest.
Even though it is whisking lighter foods such as eggs and cream, avoid using the whisk attachment for longer than 3 minutes in any 10 minute period.
