Vacuum loses suction after a few minutes but recovers after being turned off for a while

Safety first: Turn off and remove the battery.

Restore performance:

• Empty the dust bin before it reaches the MAX line, especially when vacuuming fine dust.
• Remove and thoroughly clean the cyclone shroud and mesh. Use a soft brush to remove fine dust.
• Clean or replace the pre-motor filter more frequently when vacuuming fine particles.
• Avoid using the vacuum as a construction cleanup tool; fine plaster dust can quickly clog the system and damage the motor.

Warning: Operating with a heavily clogged cyclone can overheat the motor and trigger thermal cut-out.
