Wear protective glasses and protective
gloves.
Procedure:
According to statutory requirements, only
tested and approv approved boiler decrust-
ing agents may be used.
RM 100 (Order No. 6.287-008) dis-
solves chalk and simple compounds of
chalk and detergents residues.

solves the deposits that cannot be dis-
solved using RM 100.

ating instructions of the engine manu-
