The Draper 58318 is a 20V cordless random orbit polisher designed for automotive and surface polishing. Before use, ensure the battery is charged and the backing pad is securely attached. Always test the polisher on an inconspicuous area before applying it to the entire surface. Do not apply excessive pressure, as this can damage the internal mechanics.
Product identification
The polisher features a soft grip, an on/off button, a 6-speed control dial, a dust screen, and an auxiliary handle mount. It uses a 125mm hook and loop backing pad compatible with various sponge and wool pads.

Basic operations
On/Off Switch: To turn on, press the back of the switch down and push forward; the switch will lock in the forward position. To turn off, press the back of the switch down, and it will spring back.



Variable Speed Control: Use the speed control button to select between 6 speed settings, ranging from 1,600 to 4,710 o/min. The speed is indicated by the light color (Green for 1-3, Red for 4-6).
Battery charging
This product is supplied "bare" without a battery or charger. Use only Draper D20 battery packs and chargers. To charge, slide the battery into the charger. The red LED indicates power, flashing red indicates charging, and solid green indicates a full charge. Always allow the battery to cool down after use before recharging.

Maintenance and troubleshooting
Regular cleaning keeps the tool in good working condition. Do not use solvents or fuels for cleaning. If the polisher does not operate or loses power, check the battery charge level or replace the battery if faulty. If the machine vibrates, check if the pad or bonnet is damaged or out of balance.
Safety information
Always wear appropriate personal protective equipment, including safety glasses, ear defenders, and gloves. Keep the work area clean and well-lit. Do not operate in explosive atmospheres. Ensure the tool is switched off before connecting the battery. Do not expose the tool or battery to rain or extreme temperatures.
