Regular maintenance with extended rinsing with water is the best method to renew and main-
tain the passive layer.
Each of the steps linked with maintenance presents risks of damaging the passive layer: using
hard water / overdosing detergents / using chlorine-based detergents / food residue on the
products / insufficient rinsing.....
Whenever corrosion appears, the element or step having led to it must be identified.
y Advice :
- maintain stainless steel surfaces clean and dry. Ensure there is a sufficient flow of air.
- clean daily to remove scale, grease and any food residue. Corrosion can form under these
layers by lack of air inlet.
- daily cleaning can be performed with a damp cloth. If necessary :
* use soapy water, cleaning products with low chloride content, javel-free detergents, window
degreasers.
* remove hard stains with a non metallic brush (plastic material, natural bristles or stainless
steel wool).
- do not scratch the surfaces with metals other than stainless steel, and more particularly,
never use iron brushes.
- remove fresh rust stains with soft abrasive agents or fine emery cloth.
- for larger stains, use hot oxalic acid with a 2-3% concentration. If necessary, apply a treatment
with nitric acid concentrated at 10%.
After treatment, wash thoroughly with water and wipe.
The use of acid is reserved to skilled persons and complying with regulations.
y Product to ban :
- Javel water and chlorine based products
- hydrochloric acid
- iron oxide abrasive powders
MAINTENANCE
y Pass cable A, through the half-shell B with the hexagonal-shape holes C, and through the cable
clamp D (figure 1).
y Tighten the cable clamp pressure screw.
y Position the two pins E in one of the two half-shells.
y Fasten the latter onto the winch drum with the two screws F and the two nuts G.
y Use an Allen wrench to tighten the screws.
y Remove the spring from one of the two sides.
y Pass the cable, buckle side, inside the tensioner, and under the two rollers H (figure 2).
y Remove the screw I from the winch, pass the buckle of the cable and refasten the screw.
y Reposition the spring.
