DeWalt DC500 - User Manual

The DEWALT DC500 is a versatile cordless/corded vacuum cleaner designed for professional applications, capable of vacuuming both dry and wet substances. Its dual power source allows it to operate on mains (corded) power or battery (cordless) power, making it suitable for both indoor and outdoor use. For cordless operation, the tool is compatible with DEWALT NiCd and NiMH battery packs ranging from 12 to 18 V. Beyond its primary function as a vacuum, the DC500 can also be used as a blower to clear debris from workplaces and dry damp surfaces.

Function Description

The DC500 operates by creating a powerful suction or blow force, depending on the selected mode. In vacuum mode, air and debris are drawn into the tank through the vacuum inlet. The tool is equipped with a dust filter that should always be in place during operation to ensure proper filtration. If the tool is accidentally used without the dust filter in wet vacuuming, a shut-off feature will activate when the liquid level in the tank reaches its maximum, causing a float valve to block the suction opening, stopping suction, and increasing motor speed. This mechanism prevents liquids from entering the motor housing. In blow mode, air is expelled through the blow outlet, allowing users to clear debris or dry surfaces. The tool features an on/off switch for easy operation and latches to secure the power head to the tank. A drain plug is provided for convenient emptying of liquids.

Usage Features

To operate the DC500, users should first ensure the work area is clean, well-lit, and free from flammable liquids or gases. Children, visitors, and animals should be kept away from the work area. Proper attire, including safety glasses, a face or dust mask (if dust or flying particles are present), heat-resistant apron (if particles are hot), ear protection, and a safety helmet, is recommended. The tool should always be used in an upright position to prevent liquids from entering the motor housing.

For vacuuming, the tank should be emptied and cleaned before use. The hose is connected to the vacuum inlet and secured by turning it clockwise. The appropriate accessory, such as the wide nozzle or crevice tool, is then attached to the hose nozzle. It is recommended not to mix wet and dry substances; if switching between them, the tank should be emptied and cleaned first. The DC500 can also function as a dust collector for power tools. The supplied dust extraction adaptor facilitates connecting a power tool to the hose nozzle for efficient dust and debris collection.

For blowing, the tank should be emptied and cleaned before use. The hose is connected to the blow outlet and secured by turning it clockwise. The desired accessory is then attached.

The tool automatically switches between AC (mains) and DC (battery) power. When using mains power, the cable should be fully unwound and connected to an outlet before switching on the tool. For battery power, a charged battery pack should be inserted into the battery compartment, ensuring it is fully seated. The battery compartment cover is then closed. Always switch off the tool before inserting or removing the battery pack.

Maintenance Features

Regular maintenance is crucial for the DC500's long-term performance and safety. The tool should be kept clean and in good condition. After each use, or when switching between wet and dry substances, the tank (3) should be emptied and cleaned with mild soap and a damp cloth, then carefully dried.

The dust filter (19) should also be cleaned after each use. To clean, remove the dust filter by turning it counter-clockwise from the suction opening (20). Excess dust can be shaken off by tapping the filter into a waste container. Depending on its condition, the outside of the filter can be rinsed under lukewarm running water. It is important not to wash the inside of the filter and to let it dry thoroughly if it becomes wet. A brush should not be used to clean the filter. Once clean and dry, the filter is secured back over the suction opening by turning it clockwise.

If the tool is operated without the dust filter, the suction opening filter needs cleaning. To do this, remove the filter from the suction opening (20), keeping the float valve (21) out of the way. Rinse the filter under lukewarm running water and dry it before re-installing. The float valve (21) should also be cleaned with a damp cloth.

If the shut-off feature engages, the tool should be switched off immediately, the tank emptied, and the suction opening filter cleaned. Always remember to put the dust filter back in place before resuming work.

For battery packs, ensure they are fully charged. If a battery pack no longer produces sufficient power, it should be recharged according to the charger's instructions. At the end of its technical life, battery packs should be run down completely, removed from the tool, and taken to a dealer or local recycling station for proper disposal, as NiCd and NiMH cells are recyclable.

Any repairs should be carried out by an authorised DEWALT repair agent using original spare parts to ensure safety and maintain the tool's compliance with safety regulations. Users should never attempt repairs themselves. Extension cables should be inspected for damage before use, and only outdoor-rated extension cables should be used when working outdoors.
