IMPORTANT: Draper Tools Limited recommends that this machine should not be modified or used for any application other than that for which it was designed. If you are unsure of its relative applications do not hesitate to contact us in writing and we will advise you. - Learn howto stop the compressor in the event of an emergency. - Ensure the mains voltage is compatible with the voltage listed on the compressors rating plate. - Before attempting to carry out any servicing or maintenance operations, remove the plug from the socket and purge all air from the reservoir. - Never stop the compressor using the mains switch or removing the plug from the socket. Always use the pressure switch. - After maintenance operations ensure all parts are correctly fitted before running through the set-up procedure. Always wear ear defenders when in proximity to the compressor. Keep compressors and associated tools out the reach of children. Keep animals and children out of the work area. WARNING: Avoid contact with moving parts and components prone to high temperatures. Do not operate the compressor near flammable materials or dangerous environments. Do not attempt to transport or move the compressor with the reservoir under pressure. Prior to each use inspect the compressor fully. Do not attempt to operate the compressor with damaged, faulty or missing components. Replace components immediately with genuine Draper parts. Do not expose to rain or moisture. Do not operate the compressor with the air inlet filter missing. Do not connect an air hose with a flow rate lower than that of the compressors. Do not use the compressors at temperatures below 0°C or exceeding 45°C. Do not alter or adjust any safety devices ADDITIONAL SAFETY INSTRUCTIONS - ADDITIONAL SAFETY INSTRUCTIONS FOR SAFETY VALVES - Information: The safety valves are designed and constructed for use exclusively with compressed air, free from impurities. The materials used in construction are suitable for operating the valve at the rated pressure and temperatures. The Viton or NBR gasket conserves the resistance characteristics, even in prolonged use. The valve caulking impedes calibration modification; tampering with the valve and/or changing the constructors calibration is forbidden. - Installation: Valve installation must be performed exclusively by technically prepared persons, who are responsible and in good health. Checking the integrity of the valve before installation is obligatory. Also, check that the valve pressure is no greater than the operating pressure of the tank or of the system to protect. Check that the discharge flow rate of the valve is greater than the quantity of the air to discharge. The safety valve must be positioned directly on the tank in a vertical position, in a dry, accessible place protected against the weather and far away from liquids or condensation. It must be positioned so as to have sufficient space all around for correct air discharge, without causing damage to persons and/or things. The valve rod must therefore be free in its movement when discharging. The connection between the valve and the part to be protected must be free from all kinds of choking and be as short as possible so as not to reduce the discharge flow rate of the valve itself. The connection passage area must be greater than the valve orifice area. During installation, screw on the valve with a torque spanner using the hexagonal part of the body. Apply a maximum torque of 30Nm, paying attention not to cause any deformation; using pincers, pliers, hammers or tools other than a hexagonal spanner is forbidden. Check that the inlet hole and the shutter are not blocked by glue, teflon or similar materials that could bind the shutter or other functional components. If the value is replaced, the compressor air contained in the system must be discharged first. We decline all responsibility for damage caused to persons and/or things due to failure to observe these instructions. Maintenance and inspection: The valve must not be subjected to knocks which may cause deformities. It is obligatory for qualified technicians to make sure that the safety valve functions correctly at least once a year. Valves equipped with a ring must be tested while pressurised to between 80-90% of the calibration value. Pull the ring and release immediately. During the test the valve must definitely open and discharge the air and re-close immediately when the ring is released. It is absolutely necessary to carry out this procedure with the utmost caution because this type of job can be dangerous if adequate safety measures are not taken; wear goggles, a head set and anything else necessary to protect against noise, jets of air, etc. which may be discharged from the valve. ADDITIONAL SAFETY INSTRUCTIONS FOR PRESSURE VESSELS This pressure tank is mainly intended for static use. It can only be charged with natural air within temperature and pressure limits as specified on the manufacturers plate and declaration of conformity. Ensure that tank safety and control devices are efficient and flawless. When replaced, the tank should not be under pressure. Drain the condensate off the tank every day. Check for signs of inner corrosion at regular intervals. Tank walls should have a minimum thickness of 1.0mm (DA6/1850)/2.0mm (DA25/1850). Any kind of welding to this tank is forbidden. The user shall comply with laws on pressure vessel operation in force in the country in which the tank is operated. The construction is mainly effected for permanent load by internal pressure. Cyclic loads are not considered, only for a range of 10% PS. DRAPER fll | GETTING TO KNOW YOUR EL | OIL FREE AIR COMPRESSOR } (DA25/1851C Sn SWE TE ina > © N 7 (1) 25 litre reservoir tank.

Although the compressor is equipped with an overload cut-out, Draper Tools recommend the compressor duty cycle never exceeds 50% and that continuous operation never exceeds 15 minutes. In addition to pneumatic tools the compressor may be connected to a variety of other tools intended for washing, spraying and blowing. - 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 product 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. - 6 - | ASSEMBLY Upon receipt of the compressor, ensure all components are present and have remained undamaged in transit. Retain the packing materials and packaging in case future transportation of the compressor is necessary. We recommend that the packaging is kept, at least within the period of the guarantee. - DA25/1850C WHEELS AND ANTI-VIBRATION FOOT Pass the 15mm bolt through the wheel, the compressors frame and secure with the 15mm nut. Press the rubber anti-vibration foot into position. - Positioning In order to ensure proper air flow to the ventilation grills ensure the compressor is at least 50cm from any obstacles which may impede air from flowing correctly. - Wiring the plug This unit is designed only to be used with 110 Volts. Do not fit a 3 pin 13amp plug as it will damage the unit. A 110 Volt plug must be fitted by a qualified electrician. Before carrying out the electricity connection make sure that the compressor main switch is in the off position “O”. | OPERATION AND USE ON/OFF SWITCH (Figs.1.& 2.): NOTE: Prior to connecting the compressor to the power supply ensure the pressure switch is in the off position. On initial start-up open the reservoir condensate drain bung (A)t, adjust the pressure regulator to the maximum pressure. f DAG6/1850 - Screw bung clockwise into tank to open valve. DA25/1850 - Unscrew bung anticlockwise to open valve. Pull the pressure switch (C) up to start the compressor. Allow the machine to run for 10 minutes with the air escaping from the reservoir tank before closing the drain bung (A). Ensure the tank pressure reaches 8 bar as indicated on gauge (D) before the pressure switch shuts off the motor. NOTE: When the drain bung is closed the tone from the motor will change. The compressor motor will automatically restart when the tank pressure drops to approx. 2 bar less than the maximum pressure. ATTENTION: Never stop the compressor using the mains connection. Always switch off the compressor by pressing the pressure switch button down. The compressed air will be vented from the head and allowing an easy re-start. NOTE: During correct operation a whistle of compressed air escaping/releasing will be heard when the motor stops and a protracted whistle (approx. 20-30 seconds) when ever the compressor is started with no pressure in the tank. OVERLOAD CUT OUT (Fig.3.): The compressor is equipped with an overload cut out (E) which operates as a safety device to protect the motor. Should a fault occur and begin to overheat the motor the overload cut out will automatically operate, cutting power. This prevents damage occurring to the motor. Allow 5 minutes for the machine to cool prior to attempting to reset the overload cut out (E). Press button (E). If after restarting the overload cut out is activated again, switch off the machine, disconnect the power supply and contact an authorised service agent. -8 - | OPERATION AND USE | - WORKING PRESSURE ADJUSTMENT (Fig.4.): - NOTE: For technical specifications and detailed instructions please refer to the instructions provided with the specific air tool/accessory. The outlet line pressure from the tank is adjusted using regulator (F). Rotate the regulator clockwise to increase the pressure or anticlockwise to decrease. The pressure is indicated on gauge (G). - ATTENTION: After each use set the pressure to zero to help prolong the life of the regulator and avoid damage. - AIR LINE CONNECTION (Fig.5.): The compressor comes equipped with a quick “in line” female connector (H). To insert a male connector, hold collar (1) backward. When fully inserted, release the collar. If a different style of connection is required the connector (H) can be replaced. - NOTE: When fitting the replacement ensure the threads are sealed with PTFE? tape for an air tight union. + Draper Stock No.63389. | MAINTENANCE | - NOTE: Remove the plug from the socket before carrying out adjustment, servicing or maintenance. In order to maintain the compressor to its optimum, periodical service checks must be carried out routinely. Allowances should be made to adjust the time scale for machines in occasional service with the exception of the safety valve which must be inspected by a qualified service agent every 12 months regardless of use. - AFTER THE FIRST 50 HOURS SERVICE Ensure that all fixings have remained tight, in particularly on the head and crankcase. - DAILY CHECKS: = Before every use check the airline filter/requlator/seperator. Fill the lubrication level up, empty any collected condensate and adjust the line pressure to the accessory as necessary. = After every use adjust the line pressure back to zero. - WEEKLY CHECKS: = At least once a week the build up of condensate should be drained from the tankt. t In the absence of a filter/regulator/separator to ensure a clean/dry lubricated air supply the condensate should be drained before each use. Open the reservoir condensate drain bung fully before tilting the compressor to ensure all condensate is drained. Collect the moisture in a suitable container. As the compressor is oil free the condensate will contain no lubricate/polutants so requires no special disposal. Finally close the bung, pressurise the tank fully and switch off the compressor. Open the bung to remove any remaining condensate under pressure. - NOTE: Ear defenders and safety goggles must be worn. - MONTHLY CHECKS: - Remove the foam filter to replace or clean it. Rinse the filter with water and soap. Make certain the element is completely dry prior to refitting. - ATTENTION: Never attempt to run the compressor without the filter element fitted as dust or foreign bodies can enter the pump unit resulting in serious damage. This must be carried out more frequently if the compressor is operating in a dusty environment. The motor must be correctly ventilated during operation. For this reason avoid blocking the air inlets. After use disconnect the tool from the power supply and vacuum the ventilation slots. If replacement of the supply cord is necessary, this has to be done by the manufacturer or his agent in order to avoid a safety hazard. - 10- | DISPOSAL OF POWER TOOLS | - At the end of the machines working life, or when it can no longer be repaired, ensure that it is disposed of according to UK regulations. - Contact your local authority for details of collection schemes in your area.
