mixer first before plugging in power supply.
Always start the mixer before loading the drum. Loading the drum
with drum rotating.
Do not throw material into the mixer to avoid sticking firmly to the
back of the drum. Trickle it steadily over the ram.

it from overheating. The thermal protecter restores automatically
when the motor cools down.

Cleaning

Thoroughly clean the mixer at the end of each day's operation. Keep your mixer clean. The

until the machine is useless. Dried cement should be scraped out of the drum. Do not throw
bricks into mixer drum to clean it out. Do not beat on the drum with a shovel, a hammer or
other tools to break up accumulations of dried cement mix, as damage to the mixer may result.
The drum may be scoured for approximate 2 minutes, using 1" gravel and water mixture. Then
discharge the gravel/water mixture and hose down the drum assembly inside and out. The
IP45D protection class construction of the concrete mixer enables you to hose down the drum
