GENERAL MAINTENANCE
AVOIDING CONTAMINATION
The operator has the best opportunity to avoid contamination between commodities. It is critical that the operator
clean and maintain the trailer interior and trap frame areas to avoid contamination. The interior hopper, dividers, etc.
should be inspected and cleaned thoroughly by the operator as required. Use a broom or a high pressure sprayer
to clean the interior surfaces including the dividers, wall liners and interior tub panels. Do not use a high pressure
sprayer for trap frame cleaning and washing. High pressure water could enter and damage the bearings. Access to
the interior of the trailer should be from underneath through the trap door opening. Never climb over the top of the
trailer into the interior. See section below for trap frame maintenance.
TRAILER WASHING
Washing the trailer is an important step in decreasing future maintenance. The trailer should be washed with soap
and water using a relatively soft bristle brush. Various chemicals can cause severe corrosive damage to aluminum.
The use of acid in any concentration to clean the trailer will void the warranty.
There are many different types of chemicals used today to de-ice the roadways. Many of these can cause severe
damage to the steel substructure of the trailer and diminish the appearance of the aluminum and stainless steel
components if not kept properly and regularly washed away.
A number of products hauled in the trailer will also lead to corrosion if the products are allowed to build up. Prod-
ucts that build up on the aluminum and steel members in the suspension subframe and upper coupler area should
be routinely washed off.
CORROSIVE DETERIORATION
Various chemicals can cause severe corrosive damage to your aluminum grain trailer. To prevent severe damage
to your trailer due to corrosion, contact Timpte Trailer Company Product Engineering to verify that the materials you
are hauling are compatible with the materials used in the construction of the trailer.
Corrosive deterioration caused by incompatible materials could void all or part of the
trailer warranty.
The most important preventive maintenance step to avoid corrosion is cleaning; your trailer should be washed out
after each load to minimize corrosion when hauling such items as salt, fertilizer, etc.
