Cleaning the gearbox

NOTICE
Damage to the gearbox due to increased housing temperatures resulting from dust
deposits
Dust deposits prevent heat dissipation, increase the temperature of the gearbox housing,
and can cause damage to the gearbox.
• Remove dirt and dust from the geared motor.
NOTICE
Damage to the gearbox caused by the ingress of water resulting from cleaning with high-
pressure cleaning equipment
If you clean the geared motor with high-pressure cleaning equipment, seals may be
damaged, water can penetrate into the geared motor, and the geared motor can be
damaged.
• Do not use high-pressure cleaning equipment to clean the geared motor.
• When cleaning, do not use any tools with sharp edges.
Switch off the power supply to the converter prior to cleaning.
