Many cleaning solvents are toxic, flammable, and/or may cause skin and
eye irritation. Strictly follow the manufacturer's instructions and use eye
protection, gloves, and protective clothing. Use in well-ventilated areas
away from heat and open flames. Use good personal hygiene prior to
eating, drinking, or smoking.
Do not use abrasive products that will leave grit after cleaning. Do not
allow debris and cleaning solvent to enter the cylinder bore.
Remove any carbon and varnish build-up by carefully scraping. If necessary, use a light
application of cleaning solvent.
Ensure all surfaces are clean, dry, and free of debris.
