Specified Use

The vacuum cleaner is suitable for the vacuuming of dust, solid materials (broken glass, nails etc.), and liquids of any kind with the exception of highly inflammable, combustible liquids and material that is hotter than 60 °C. This device is not designed for use by persons with physical, sensory or mental disabilities, or with insufficient experience and/or knowledge, unless they are supervised by a person responsible for their safety, or have received instructions on how to use the device by this person. Pay attention to the country-specific regulations, as well as the specifications of the material producer. This product is designed for industrial use. Dust containing asbestos must not be vacuumed. Inflammable dust must not be vacuumed. No inflammable or explosive solvents, material saturated with solvent, dust that represents an explosion hazard, liquids such as petrol, oil, alcohol, thinner or material that is hotter than 60 °C are allowed to be vacuumed. This would cause an explosion and fire hazard! You are not allowed to use the appliance in the vicinity of inflammable gases or substances. The vacuum cleaner is suited for the separation of dry, non-flammable dust, non-flammable liquids, wood dust and dangerous dust with workplace limit values > 1 mg/m³. The user bears sole responsibility for any damage caused by improper use. Generally accepted accident prevention regulations and the enclosed safety information must be observed.

Keep all enclosed documentation for future reference, and ensure that you only pass on your device together with this documentation. Before using the appliance, the user must receive information, instructions, and training material on using the appliance and the materials for which it is to be used (including details on safe disposal of the extracted material).

Special Safety Instructions

For your own protection and for the protection of your vacuum cleaner, pay attention to all parts of the text that are marked with this symbol! Never allow children to use the machine. Children should be supervised to ensure that they do not play with the device. Caution! Only use accessories that are included with the appliance or specified Operating Instructions. The use of other accessories may impair safety. You must not perform any work other than that described here. In the event of misuse, improper operation or unprofessional repair work no liability shall be assumed by us for any damage incurred. Do not operate appliances or accessories under the following conditions:

If the appliance has recognisable damage (cracks/breaks),
If the mains connection lead is defective or shows signs of cracking or aging,
If there is a suspected non-visible defect (after a fall).

ENGLISH 12 Do not point the nozzle, hose, or tube at people or animals. If any foam or water egresses, switch off immediately. Empty the container and, if need be, the pleated filter. Never sit or stand on the appliance. Always set up the connection lead and hose so there is no danger of tripping. Do not pull the connection lead over any sharp edges and do not kink or pinch it. If the connection lead of the appliance is damaged, it must be replaced by a special connection lead. See the chapter on Repairs. Always connect to a socket with protective contact. Do not use any damaged extension leads. Never insert or remove the mains plug with wet hands. Only pull on the mains plug, not on the lead. The plug socket on the appliance may be used only for the purposes defined in the usage instructions. Do not leave the appliance unattended. If there is a long work interruption, disconnect the mains plug. The vacuum cleaner should not be used or stored outside in wet conditions. IMPORTANT – This machine must only be stored indoors. Acids, acetone and solvents can corrode the appliance components.

Prior to any servicing work, clean the appliance. Switch off the appliance after each use and pull out the main plug. Steam cleaners and high-pressure cleaners must not be used to clean the vacuum cleaner. Mold contamination can result if the appliance is not cleaned for an extended period, especially if used in areas where foodstuffs are processed: Always clean and disinfect the vacuum cleaner immediately after use. Never open the appliance outdoors during rain or storms. The appliance must not be operated in areas with an explosion hazard. Ensure that the vacuum cleaner is steady. If the extracted air is discharged into the room, ensure there is an adequate air change rate (L) in the room. Observe the regulations that apply in your country. Caution! This appliance contains dust that is harmful to health. Discharge and maintenance operations (including disposal of the dust collection containers) must only be carried out by qualified specialists wearing appropriate protective clothing and equipment While the appliance is suitable for extracting substances that pose a slight threat to health, it is not appropriate for reducing wood dust in inhaled air. Dust from materials such as paint containing lead, some wood species, minerals, and metal may be harmful. Contact with or inhalation of the dust may cause allergic reactions and/or respiratory diseases to the operator or bystanders. Certain kinds of dust are classified as carcinogenic, such as oak and beech dust, especially in conjunction with additives for wood conditioning (chromate, wood preservative).

Initial Operation

Assembly
Insert the guide roller axles (8) until they engage Fig. A. Fit the wheels (9) and secure with screws (place a shim under the screw head) Fig. B. Fit the pipe support (10) until it clicks into place, as shown (for ASA 32 L only) Fig. C.

Fitting the pleated filter Fig. D+E: Fit the pleated filter (11) on the housing as far as the limit stop and secure by twisting the bayonet fitting (12).
Inserting a Fleece Filter Bag
Fleece filter bags (13) are not suitable for wet vacuuming. We recommend using fleece filter bags for:
- Applications, where small amounts of fine dust are created (e.g. spot-grinding and grinding of paint and lacquer coatings, extraction of drilling applications with small diameters < 10 mm of short duration, etc.).
- Use of machines, such as: routers, planers, small grinding machines, etc.
  Switch off the device, remove the mains plug and open the snap locks (3). Remove the upper part (1) of the device from the container (4). Push the fleece filter bag together with its cardboard tab into the filter bag holder located on the suction piece (inside the container) Fig. F. Adjust the fleece filter bag (13) so that it is flush with the container wall and is not damaged when you replace the upper part.

The Appliance

Switching On/Off, automatic operation
Use the switch (5) to turn the machine On/Off.

Switch position I: “ON”
Switch position 0: “OFF”
For ASA 32 L only:
Use the (6) switch to activate automatic On/Off. If the (6) switch is in the “A” position and the (5) switch is in the “I” position, the vacuum cleaner can be activated or deactivated by a power tool connected to the power socket (7).

The total maximum permissible current consumption (of the vacuum cleaner and connected unit) must not exceed the value Imax (see table, page 2). Caution! Ensure that the power tool is switched off when plugging it in. Regardless of the switch position, the plug socket is always live when the mains plug is plugged in. If the switch is (5) in the “0” position, you can use the plug socket as an extension lead (e.g. for a light fitting). If the (6) switch is in the “A” position and the (5) switch is in the “I” position, the vacuum cleaner can be activated or deactivated by a power tool connected to the power socket (7).

Use

Dry Vacuuming

Vacuum using a dry filter, dry device, and dry accessories only. If the cartridge is damp, dust may stick and form a crust. Always use the fleece filter bag (13) together with the pleated filter (11) .
Wet-vacuuming
Never operate the machine without inserting a pleated filter (11). The machine may be destroyed and water may also escape. Vacuum without fleece filter bag (13) . The pleated filter (11) is suitable for wet vacuuming. Before carrying out any wet vacuuming, remove the dry vacuumed material. This process will prevent severe soiling and encrustation. The float valve interrupts the suction process if the container is full. Switch off the motor, empty container and pleated filter (11), if required. After switching off, some water may run back out of the hose. Before emptying, first of all take the suction hose out of the liquid. Use a dry pleated filter to carry out dry vacuuming afterward. If you are frequently switching between dry and wet vacuuming, we recommend the use of a second (replacement) pleated filter. Allow the pleated filter, container, and accessories to dry: otherwise, dust may adhere to damp components.

Transport

Leave the hose on the machine to prevent dust from accidentally being released. Wrap the suction hose about the vacuum cleaner. Wind the mains connection lead (2) about the upper part, as shown. The upper part (1) must be securely sealed to the container (4) – check that the snap locks (3) are closed.
