Unless other instructions are provided, perform maintenance under the following conditions:

 

 

The unit is powered down and cannot be started.

 

The protective locks on the controls are in the locked out position.

 

Do not attempt any repairs that are not understood. Use the proper tools. 

Replace any equipment that is damaged or repair the equipment.

 

 

Pressurized Air and Water 

 

Pressurized air and/or water can cause debris and/or hot water to be blown out which could result in personal injury.

 

The maximum air pressure for cleaning purposes must be reduced to 205 kPa (30 psi) when the air nozzle is deadheaded and 

used with effective chip guarding (if applicable) and personal protective equipment. The maximum water pressure for cleaning 

purposes must be below 275 kPa (40 psi). When pressurized air and/or pressurized water is used for cleaning, wear protective 

clothing, protective shoes, and eye protection. Eye protection includes goggles or a protective face shield. Always wear eye 

protection for cleaning the cooling system. Avoid direct spraying of water on electrical connectors, connections, and 

components. When using air for cleaning, allow the machine to cool to reduce the possibility of fine debris igniting when 

redeposited on hot surfaces. 

 

Fluid Penetration

 

Always use a board or cardboard when you check for a leak. Leaking fluid that is under pressure can penetrate body 

tissue. Fluid penetration can cause serious injury and possible death. A pinhole leak can cause severe injury.

 

If fluid is injected into your skin, you must get treatment immediately. Seek treatment from a doctor that is familiar with this 

type of injury.

 

 

Containing Fluid Spillage

 

 

Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, 

adjusting, and repair of the product. Be prepared to collect the fluid with suitable containers before opening any 

compartment or disassembling any component containing fluids.

 

Dispose of all fluids according to local regulations and 

mandates.

 

 

Dispose of Waste Properly 

 

Improperly disposing of waste can threaten the environment. Potentially harmful fluids should be disposed of according to local 

regulations. Always use leak proof containers when you drain fluids. Do not pour waste onto the ground, down a drain, or into 

any source of water. 
 

Burn Prevention 

 

Do not service an operating unit. Allow liquids to cool before any maintenance is performed.
