Renfert basic quattro Instruction Manual

Areas of Caution
Never operate a sandblaster without a suitable dust extractor or suitable personal protective clothing as
this can be detrimental to your health. The type of dust extractor must relate to the type of dust
produced by your sandblasting work. It is imperative to adhere to your trade association regulations
(ZH 1/487).
Improper use can risk the danger of damage to eyes and skin. Never blast towards your eyes or onto
unprotected skin.
Before operating, check that the tank lid is correctly fitted. An incorrectly sealed lid can work loose with
a force similar to an explosion. There is thus a risk of harm from flying components and from the sudden
escape of abrasive.
Always disconnect the unit from the compressed air and electricity supplies before carrying out any
maintenance.
Never clean the tank or tank lid with cleaning fluids containing solvents! Solvents may cause a build-up
of microcracks in the acrylic therefore creating a risk of explosion.
As long as only the compressed air supply hose is connected, do not operate the foot-switch as the
hose will thrash around and quite possibly cause injury.
Before changing the fluorescent lamp make sure the lamp is unplugged.
Do not push or bend the lamp when exchanging (danger of breaking). If necessary wear gloves or use
a cloth for protection.
