3.2 Cleaning

1)Cleaning Notes

Cleaning is necessary due to accumulation of oil and dirt on the part. Use suitable cleaning methods such as steam purging light oil rinsing, neutral cleanser washing, trichloroethylene steam cleaning and shakable washing solution (magus Solution) used in washing machine. As the damaged locations of the part may get exposed in course of cleaning, be sure to make a careful check while performing the cleaning.

2)Cleaning of metal parts

(1)Light oil cleaning

Light oil is different from other kinds of solvent and it has less penetration or dissolving capacity to dirt. Therefore, tools like wire brush should be used to remove dirt with the exception for precise and fine finish surface. Follow this way to make the cleaning for two times

(2)Alkaline solution washing

Do not use alkaline solution to wash alloy parts. But alkaline solution is suitable for cleaning steel and cast iron parts

Note: While cleaning with alkaline solution, take care not to allow it to contact your skin and eyes, and make instant washing in case of any touch, Therefore, a kind of neutralizer (such as boric acid solution) should be readily made available for use at hand.

3)Cleaning of rubber parts

Do not use any mineral washing oil. Wash it in alcohol or just use a piece of clean cloth to wipe the dirt.

4)Purge of oil pipeline

Use steel wire to get through the oil pipeline to confirm the pipeline is through. Fill the solvent into the oil pipeline through anozzle under pressure for cleaning.

5)Anticorrosive protection

After completely remove the dirt and oil on part surface, apply a coat of clean engine oil for prevention of rust corrosion
