POWER SUPPLY

CONNECTING YOUR MACHINE TO THE POWER SUPPLY: (230V ONLY)
To eliminate the possibility of an electric shock your machine has been fitted with a BS approved, non rewireable moulded plug and cable which incorporates a fuse, the value of which is indicated on the pin face of the plug. If the plug is marked with the symbol and the fuse needs replacing, an approved BS1362 fuse must be used of the same amp rating. If the plug is not marked, a fuse with the symbol, BS Kitemark, or both and **** BS Kitemark, of the same amp rating should be used.

The fuse cover is detachable, never use the plug with the cover omitted. If a replacement fuse cover is required, ensure it is the same colour as that visible on the pin face of the plug (i.e. red). Fuse covers are available from your Draper Tools stockist.

If the fitted plug is not suitable, it should be cut off and destroyed. *The end of the cable should now be suitably prepared and the correct type of plug fitted. See below.

*WARNING:
A plug with bare flexible wires exposed is hazardous if engaged in a live power socket outlet.
WARNING: THIS APPLIANCE MUST BE EARTHED.
The mains lead is coloured Green and Y ellow – Earth, Blue – Neutral and Brown – Live. As these colours may not correspond with the coloured  markings identifying the terminals in your plug, proceed as follows:
The wire which is coloured green and yellow must be connected to the terminal in your plug marked with the letter ‘E’ or by the earth symbol or coloured green or green and yellow.
The wire which is coloured blue must be connected to the terminal which is marked with the letter ‘N’ or coloured black or blue.
The wire which is coloured brown must be connected to the terminal which is marked with the letter ‘L’ or coloured red or brown.

EXTENSION LEAD CHART:
Extension lead sizes shown assure a voltage drop of not more than 5% at rated load of tool.

GETTING TO KNOW YOUR COMPRESSOR

DA50/190 Shown.

UNPACKING: After removing the packing material, make sure the product is in perfect condition and that there are no visible damaged parts. If in doubt, do not use the compressor and contact the dealer from whom it was purchased.
The packaging materials (plastic bags, polystyrene etc.,) must be disposed of in an appropriate refuse collection container. These materials must not be left within the reach of children as they are potential sources of danger.

OPERATION AND USE

POSITIONING:
Do not stand the compressor on any surface with a 15° or greater tilt as this will lead to possible running problems.
Allow a minimum gap of 50cm  around the compressor to aid connection and airflow.
In addition to pneumatic air tools, your compressor may be connected to several accessories  suitable for blowing, washing and spraying for example. For technical specifications and detailed instructions, please refer to the instructions provided with the individual accessory.
After unpacking the compressor for the first time it will be necessary to remove the plastic transit bung and replace it with the supplied dipstick.

NOTE: It is advisable to store this bung, should the compressor require transporting in the future.

Make sure that the level of oil ranges between the max. and the min. mark (Fig.1).

After the first 50 working hours, replace the oil with one of those listed (see page 10).
When the installation procedure is complete, the compressor is ready for use. Make sure the pressure switch is positioned ‘OFF’. Switch on the power  then position the pressure switch to the ‘ON’ position to start the compressor (Fig.2).

When starting the compressor for the first time, leave it running for about 10 minutes with the drain cock (A) open (Fig.3).

DA25/190 does not have a tap. Instead, run for 10 minutes with a coupling inserted into the connector.
After this time, ensure the drain cock (A) is closed correctly. Make sure that pressure in the tank is correct and that the compressor stops automatically when the max. pressure is reached. The pressure is monitored on gauge (B) (Fig.4). 

This operation is automatically controlled by the pressure switch which stops the motor when the max. pressure allowed is achieved, and starts it again when the pressure goes below the minimum threshold (about 2 bar less than the max. pressure).

Never unplug the compressor or switch off the main switch to stop the compressor. Always position the pressure switch to the off position.

OPERATION AND USE

ADJUSTING THE PRESSURE SWITCH
(Fig.5):

Note: This is the only operation where it is acceptable to switch the compressor off without using the pressure switch.

To decrease the pressure switch, run the compressor up to the desired capacity for the pressure switch to be set. At this point, turn the mains power off and do not operate the red button on the pressure switch as this will release the pressure. Disconnect the machine from the power source before  removing cover (D). With this removed, the adjustment bolt (C) will be visible. Adjust this anticlockwise gently until the switch is heard to release the pressure. Replace the cover and tighten the screw. The switch will now be set to the new pressure.

To increase the pressure switch, remove the switch cover (having disconnected the machine from the power supply) and turn the adjustment bolt clockwise 3 turns and replace the switch cover. Run the compressor up to the desired capacity for the pressure switch to be set ( do not let the compressor run past its maximum pressure). At this point turn the mains power off and disconnect from the supply. Remove the cover and adjust the bolt anti- clockwise gently until the switch is heard to release the pressure. Replace the cover and tighten the screw. The switch will now be set to the new pressure.

HOW TO ADJUST WORKING PRESSURE
(Fig.6): See in the instruction manual for the rated pressure value of the accessory you are going to use.
By means of the pressure reducer (G) you can adjust delivery air pressure. Turn the knob clockwise to increase the pressure or anti-clockwise to ecrease the pressure. Check the operating pressure value on pressure gauge (F).
After having used your compressor, set pressure to zero by turning knob (G) so as to avoid damaging the pressure reducer.

OPERATION AND USE

OVERLOAD CUT-OUT
(Fig.7):

The compressor is equipped with an overload cut-out (H) which operates as a safety device to protect the motor. In case of motor overload or verheating due to operation troubles. The safety device will automatically activate, disconnecting the compressor and avoiding possible motor damages.

To restart the compressor, proceed as follows:

• Allow three minutes.
• Position the pressure switch to”0″ OFF .
• Manually reset the thermal cut-out.
• Position the pressure switch to “1” ON.

If you restart the compressor and the overload cut-out releases again, turn the main switch to position “0” OFF , unplug the equipment and contact the Authorized Service Centre.

If disconnection is required from the air tap assembly, ensure the tap is fully closed to stop air loss from the tank.

NOTE: After reconnection is complete, ensure that the tap is opened again.
It is essential to connect air line, air filter separator and lubricator to ensure a good, clean air supply is provided for the tool.
(NOTE: If the intended tool for use is a spray gun, use only a filter separator as lubrication will cause contamination of the material being sprayed).

To ensure an optimum air supply, please refer and carry out the following procedures as recommended. Contents/Declaration  pecification/Guarantee Power Supply General Safety Instructions Getting to Know Your Compressor Operation and Use Maintenance

MAINTENANCE

Some of the operations listed in this section will require the compressor to be returned to an Authorized Service Agent.
Before carrying out any service or routine operation to your compressor, ensure the power has been disconnected and all pressure has been released from the tank, so as to prevent any sudden unexpected restart. After any maintenance operation, make sure all components have been fitted correctly.

In order to keep your compressor in good working conditions, we recommend you to perform periodical servicing operations.

Before performing any maintenance operation, switch off the compressor and ensure all air in the tank is released.

OPERATIONS TO BE CARRIED OUT AFTER THE FIRST 50 WORKING HOURS:
Check that all screws are properly tight, paying special care to the head and crank case. Replace the lubricant with one of the recommended oil listed (page 10).
Never mix different oils together. Do not use non-detergent oils or low quality oils as they have very poor lubricating properties.

Do not pour out oil in the environment. Always contact your local body in charge of the collection.

WEEKLY OPERATIONS:
Check the oil level and if necessary top up. Do not exceed the mark corresponding to the max. level. Make sure the oil does not drop below the minimum so as to avoid any damage or seizure.

Drain condensation, while the tank is pressurised by opening the valve (I) located under the tank. Open the valve by turning it anti-clockwise (Fig.8)

with a container under the valve. Keep the compressor in a position to allow all condensation to flow out completely.

MONTHLY OPERATIONS (OR MORE FREQUENTLY IF THE COMPRESSOR OPERATES IN VERY DUSTY AREAS) (Fig.9):

Remove the suction filter (J) and replace or clean the filtering component. Do not operate the compressor without the suction filter fitted, as foreign bodies or dust could seriously damage the inside components.

OPERATIONS TO BE CARRIED OUT EVERY 6 MONTHS (Fig.10):

Pull out the oil dipstick and loosen the bolt (K) to change the oil. Collect the oil into a suitable container. Y ou should perform this operation when the
compressor is hot so as to allow the oil to drain rapidly and completely. Tighten the bolt (K) and pour in the new oil up to the max. level and no higher.

It is advisable to clean all the finned parts of your compressor, so as to keep the cooling system efficient and to ensure a long work life to your machine.

OPERATIONS TO BE CARRIED OUT EVERY 2 YEARS:
Check the non-return valve and if necessary replace the seal. Check intake and delivery valves on valve plates.

Recommended Oils:
Recommended oils with ISO 100 viscosity for compressors, in accordance with DIN51506VDL 100-E Standards and ISO6521:L-DAC Specifications (suitable for room temperature ranging from +6°C and +25°C).

Use oils with an ISO 46/68 viscosity for a room temperature ranging from 0°C to + 5°C
Use oils with an ISO 150 viscosity for a room temperature ranging from + 26°C to + 45°C.
