GENERAL CLEANING INSTRUCTIONS - Continued
· Petroleum solvents may not be used on parts that are in contact with hydraulic fluids.
Failure to comply may result in damage to equipment.
· Do not clean tires, lubricants, seals, rubber hoses, or electrical components with a solvent
mixture. Failure to comply may result in damage to equipment.
Cleaning Solvents. Use only approved cleaning solvents to clean parts. Solvent cleaning compound is
commonly used. Work in a well-ventilated area.
Compressed air used for cleaning and drying purposes shall not exceed 30 psi (207 kPa).
Use only with chip-guarding and personal equipment (goggles/shield, gloves, etc.). Failure
to comply may result in serious injury or death to personnel.
Deposit Removal. After soaking parts in solvent, wash away deposits by flushing or spraying. Where
necessary, brush with a soft bristle brush moistened in solvent. Use compressed air to dry all parts, except
bearings. Bearings must be allowed to air-dry.
Tools. Do not use scrapers, wire brushes, abrasive wheels, or compounds in cleaning parts, unless called for
in detailed instructions.
Ball and Roller Bearings. When cleaning ball or roller bearings, place them in a basket and suspend basket
in a container of solvent cleaning compound. If needed, use a brush to remove caked-on grease, chips, and
so on. Avoid rotating a bearing before solid particles are removed, to prevent damaging races and balls. When
bearings have been cleaned, coat them lightly with lubricating oil to remove solvent.
Rubber Parts. Do not clean O-rings or other rubber parts in solvent cleaning compound. These parts should
be wiped clean with a clean, dry, lint-free cloth.
Exterior Parts. Steam-cleam all exterior parts thoroughly before removing. This will make inspection and
Degreasing Machine. Use a degreasing machine to remove heavy grease and oil accumulations from metal
Parts should be dipped in rust-preventive compound within two hours after degreasing.
Failure to comply may result in corrosion on parts and damage to equipment.
Passages. After removing parts from degreasing machine and before coating with rust preventive, check all
oil passages and cavities for dirt or blockage. A thin, flexible wire should be run through oil passages to ensure
they are not clogged. Individual passages that are dirty may be cleared using a spray gun and solvent cleaning
Electrical Parts. Electrical parts, such as switches, that use insulating materials, should not be soaked or
sprayed with cleaning solutions. Clean these parts with a clean, lint-free cloth moistened with solvent cleaning
