EQUIPMENT SAFETY

• 

Never place your hands, fingers or other body parts near the compressor’s moving parts during operation. Ensure that the equipment is 
isolated from the power supply and all switches in the 

OFF

 position before carrying out maintenance, repairs or adjustments.    

• 

Never operate this compressor without all guards or safety features in place and in proper working order. If maintenance or servicing requires 
the removal of a guard or safety features, be sure to replace the guards or safety features before resuming operation of the compressor. 

• 

Always wear safety goggles or equivalent eye protection. Compressed air must never be aimed at anyone or any part of the body. 

• 

When not in use, the compressor should be stored in dry place. Keep out of reach of children. Keep children and animals away from the work 
area.  

• 

Clear all work areas of unnecessary tools, debris, furniture etc. prior to use. Cluttered work areas can lead to injuries.   

• 

Do not wear loose clothing or jewellery when operating this equipment. They can be caught in moving parts. Wear protective hair covering to 
contain long hair. 

• 

Follow instructions for lubricating this equipment as required.  

• 

Watch what you are doing and remove any potential distractions before use. Use common sense at all times.  

• 

Do not operate this equipment when you are tired or if you are under the influence of alcohol, drugs or medication that makes you drowsy. 

• 

Check for the correct alignment of moving parts, binding of moving parts, condition of parts, mounting, and air leaks, and any other issues 
that might affect the safe operation of this equipment. A guard or other part that is damaged should be properly repaired or replaced by 
an authorized Jefferson service centre unless otherwise indicated elsewhere in this instruction manual. Have defective pressure switches 
replaced by an authorized service centre. Do not use compressor if the switch does not turn it on and off. 

• 

Operate the compressor according to the instructions provided in this manual. Never allow the compressor to be operated by children, 
individuals unfamiliar with its operation or unauthorized personnel. 

• 

Keep all screws, bolts, and plates tightly mounted. Check regularly.  

• 

The motor air vent must be kept clean so that air can freely flow at all times. Check for dust build-up frequently and clean as required. 
 

• 

If the equipment appears to be operating unusually, making strange noises, or otherwise appears defective, stop using it immediately and 
arrange for repairs by a authorized service centre. 

• 

Solvents such as petrol, thinner, benzine, carbon tetrachloride, and alcohol may damage and crack plastic parts. Do not wipe them with such 
solvents. Wipe plastic parts with a soft cloth lightly dampened with soapy water and dry thoroughly.  

• 

Only use Jefferson approved replacement parts. Non-approved parts will void your warranty and can lead to malfunction and resulting 
injuries. Genuine parts are available from Jefferson your dealer. 

• 

Do not modify the compressor for any use other than which it was designed for by the manufacturer.  Do not tamper with or attempt to adjust 
the tank, pressure switch or safety valve. Never strap anything to the tank. Do not subject the tank to impact, vibration, heat, abrasion or 
corrosive materials. 

• 

Always contact an authorized service centre for advice on any repairs. Unauthorized modification may not only impair the compressor 
performance but may also result in accident or injury to repair personnel who do not have the required knowledge and technical expertise to 
perform the repair operations correctly. 

• 

When the compressor is not in use, ensure the pressure switch is turned off, disconnect the equipment from the power source and open the 
drain cock to discharge the compressed air from the air tank. 

• 

To reduce the risk of burns, do not touch tubes, heads, cylinder and motors. During or immediately after use. Allow equipment to cool down 
before carrying out maintenance, repairs or adjustments.  

• 

Never direct the output jet of air at persons or animals. Ensure air supply valve is turned 

OFF

 before disconnecting the air supply hose. 

• 

Read the all safety instructions for any tool or accessory used with the compressor and ensure the safe working pressure of any appliance 
used exceeds the output pressure of the compressor. If you are using a spray gun it is important to ensure that the work area has sufficient 
ventilation in place.   

• 

Do not operate in the vicinity of flammable liquids, gases or solids.   

• 

Do not operate the compressor without an air filter or restrict the air flow around the equipment. 
 

• 

When the compressor is not in use ensure that it is switched off, disconnected from the power supply and the air and moisture drained from 
the tank.
