Parts Cleaning Equipment

2. Introduction (1 of 2)
Tools and equipment are very important to an efficient and effective shop operation.
Provide means for work to be undertaken on vehicles
Purchase, use, and maintenance is very important to overall performance of any shop.

3. Introduction (2 of 2)
Always use tools and equipment the way they are designed to be used.
Identify the most effective tools to do the task.
Inspect the tool before using it.
Use it correctly.
Clean and inspect it after you use it.
Store it in the correct location.

4. Pressure Washers and Cleaners (1 of 6)
Powered by an electric motor or gasoline engine fitted to a high-pressure pump
Pressure washer takes water at a normal pressure and boosts it through the high-pressure pump; it then exits a cleaning gun.

5. Pressure Washers and Cleaners (2 of 6)
Cleaning gun
Has a high-pressure nozzle
Focuses high-pressure water to quickly clean accumulated dirt and grease from components
Some have a provision for detergent to be injected into the output.
Others have the ability to heat the water.

6. Pressure Washers and Cleaners (3 of 6)
Pressure washers are dangerous because of high pressure and high temperature.
Always wear appropriate PPE.
Goggles or face shield
Protective gloves
Close-fitting clothes with long sleeves and full-length pants
Leather-type boots or shoes

7. Pressure Washers and Cleaners (4 of 6)
Using pressure washers
Fixed washers for cleaning components
Mobile pressure washers can be used to wash vehicle systems and engine compartments.
Incorrect handling can result in damage of the washer or vehicle components you are cleaning and health risks to yourself and coworkers.

8. Pressure Washers and Cleaners (5 of 6)
Using pressure washers (cont’d)
Does not create dust
Read instructions before use.
Be careful when cleaning exterior paintwork.
Don’t spray in areas where water and water-based solvents can have effect on electrical equipment.

9. Pressure Washers and Cleaners (6 of 6)
Using pressure washers (cont’d)
If washer results in wheel brake units getting wet, ensure that vehicle is driven for a short distance with the brakes slightly applied.
Correct disposal of contaminated materials is a top priority.

10. Spray Wash Cabinets (1 of 3)
Sprays high-temperature, high-pressure cleaning solutions on parts inside sealed cabinet
Act like a dishwasher for parts
Reduce labor required to clean parts
Variety of sizes for different-sized parts and provide high level of cleaning performance

11. Spray Wash Cabinets (2 of 3)
Cleaning solution is designed to effectively clean without leaving residue.
Most are fitted with a filtering system.

12. Spray Wash Cabinets (3 of 3)
Using spray wash cabinets
Read instruction before use.
Must incorporate a built-in waste recovery system or be used only where contaminated washer fluids can be captured to be disposed of.
Follow safety instructions.
Note the type of cleaning agent used.
Correct disposal of contaminated materials is a top priority.

13. Solvent Tanks (1 of 3)
A cleaning tank filled with a suitable solvent to clean parts
Available in different sizes
Some have a pump that pushes solvent out a nozzle into a sink where it can be directed.
A brush either on the nozzle or separate from it can be used to loosen grease and grime.
Solvent falls back into bottom of solvent tank where heavier residue can settle at bottom.

14. Solvent Tanks (2 of 3)
Some are designed so parts can be immersed into tank on racks or suspended on pieces of wire and slowly lowered and soaked in tank for a period of time.
Some have an agitation system or use a heated cleaning fluid to speed up process.
May have a circulation system and filters to remove debris and residue in the solvent

15. Solvent Tanks (3 of 3) Using solvent tanks
Familiarize yourself with equipment prior to use.
May use potentially poisonous and/or flammable chemicals to clean parts
Note the type of solvent being used and take all necessary precautions as listed on the MSDS.
Correct disposal of contaminated materials is a top priority.

16. Brake Washers (1 of 4)
Used to wash brake dust from wheel brake units and their components
Designed to capture brake dust before it enters shop environment
Brake dust may contain asbestos.
It wets down dust on brake parts and washes it into a cleaning tray.

17. Brake Washers (2 of 4) Incorporate a built-in waste recovery system
Contaminated washer fluids can be captured to enable disposal.
Normally designed to operate at low pressure and use range of cleaning agents
A low-pressure air blower may be provided to remove fluid from component into tray area and back to tank by gravity

18. Brake Washers (3 of 4)
Avoid using solvent when cleaning brake components.
Never use kerosene as a general cleaning agent to clean brake components.
Soapy water is a good cleaning agent for brake components.

19. Brake Washers (4 of 4) Using brake washers
Aqueous solution not suited for cleaning greasy residue

20. Sand or Bead Blasters (1 of 4)
Use high pressure to blast small abrasive particles to clean the surface of parts
Can occur in cabinet or portable models available for use in open-air situations
Cabinets contain blasting operation in a controlled, safe environment.
Best for smaller parts that can fit into cabinet
Portable systems can blast larger parts.
Require more protection

21. Sand or Bead Blasters (2 of 4)
Cabinet is fitted with:
A hand-operated blasting nozzle
Viewing port
On/off switch (often foot-operated)
Openings with tough rubber gloves sealed in so operators’ hands are protected during use

22. Sand or Bead Blasters (3 of 4)
Wet sand or bead blasters are also available.
Have added advantage of reducing amount of dust and providing additional cleaning

23. Sand or Bead Blasters (4 of 4)
Using sand or bead blasters
Cleans paint, corrosion, or dirt from metal parts
They can remove metal from surface of components.
Available in a range of makes and models

24. Cleaning Tools and Equipment (1 of 3)
Clean tools work more safely and efficiently.
At end of day, clean tools and equipment and check for damage.
Electrical current can travel over oily or greasy surfaces.
Shop equipment should have maintenance schedule.

25. Cleaning Tools and Equipment (2 of 3)
Store commonly used tools in an easy-to-reach place.
Keep a trash can close to work area and place any waste in it as soon as possible.
