Tolsen MP20 LI-Ion Cordless Drill 87211 Instruction Manual

Overview

The MP20 LI-Ion Cordless Drill 87211 is a compact 20V battery-powered drill designed for everyday drilling and screwdriving tasks around the home, workshop, or jobsite. It suits users who want a cordless tool with variable speed, two gear ranges, reverse rotation, a keyless chuck, and a built-in work light for better visibility.

This model is part of the TOLSEN MP20V lithium-ion platform, so its battery is intended for compatible tools in the same system. The drill is built for general-purpose fastening in wood and drilling in wood and metal.

Detailed description

The MP20 LI-Ion Cordless Drill 87211 combines a keyless drill chuck, two-speed gearbox, torque selector, trigger-controlled speed, and a forward/reverse switch in one handheld body. The torque selector lets you match the drive force to the task, while gear 1 is better for screwdriving and gear 2 is intended for drilling.

Key parts include the drill chuck, torque selector, gear switch, motor vents, soft-grip handle, trigger switch, lock button, battery pack, work light, direction switch, electricity indicator, and belt clip. The built-in light turns on when the trigger is pressed, which helps in dim work areas. The electricity indicator gives a quick battery-status reference during use.

Safety

Read all warnings and instructions before use, and keep the manual with the original receipt for future reference. The drill should never be used by children, and younger or inexperienced users should only operate it with proper supervision and instruction.

Wear eye protection and, depending on the job, hearing protection, gloves, and breathing protection. Keep loose clothing, jewelry, and hair away from moving parts. Make sure the work area is bright, uncluttered, and free from flammable vapors, liquids, or dust.

Remove the battery before changing bits or making adjustments, and never carry out setup with the tool switched on. Do not change rotation direction while the drill is running. Keep hands clear of the chuck and bit, and wait for the tool to stop completely before putting it down.

Battery and charger safety matter as much as tool handling. Charge only with the approved charger, use only compatible battery packs, and avoid exposing the battery to heat, fire, moisture, or metal objects that could short the terminals. The charger is for indoor use only.

Setup and operation

Charging the battery

Slide the battery onto the charger until charging begins. A red light indicates charging, and a green light shows that the battery is fully charged. A recently discharged 2.0Ah battery normally takes about 1 hour to charge. If the battery was left empty for a long time, charging can take longer.

The battery should be charged in a temperature range of 5 to 40°C, with room temperature around 20°C being ideal. After charging, let the battery cool for about 15 minutes before use. Do not leave batteries on charge for extended periods.

Fitting and removing the battery

To install the battery, align it with the battery slot and slide it in until it clicks and locks. If it does not seat easily, stop and check that the contacts and slot are clean and undamaged. To remove the battery, press the lock button and slide the pack out.

Installing bits and accessories

Remove the battery first. Open the chuck by turning it counterclockwise, insert the drill bit or accessory in the center, then tighten the chuck clockwise. After tightening, run the tool briefly to confirm the bit spins straight and smoothly.

Do not use accessories with a maximum speed lower than the drill’s no-load speed. Never tighten the chuck by holding the front of it and switching the drill on.

Direction control

The forward/reverse switch controls rotation direction. Push it to the right for counterclockwise rotation and to the left for clockwise rotation. When the switch is centered, the drill is locked and cannot start, which helps prevent accidental activation.

Torque control and gear selection

Use the torque ring to choose the clutch setting for the task. Higher numbers mean higher torque. For screwdriving, use gear 1 and a suitable torque setting. For drilling, use gear 2 for higher speed. Gear 2 should not be used for driving screws and fasteners.

When in doubt, begin with a lower torque setting and increase it as needed. Always check the bit manufacturer’s recommended speed range before use.

Switching on and using the drill

Press the trigger to start the drill. The built-in work light turns on at the same time. Speed is variable and depends on how far the trigger is pressed. Releasing the trigger stops the tool.

Screwdriving

For screwdriver bits, use a universal bit holder rather than inserting the bit directly into the chuck. Set gear 1 and choose a torque level that matches the fastener and material. Do not use drill mode when driving screws.

Drilling wood

Select the proper gear, switch the mode to drill, and use bits rated for wood and within the tool’s capacity. Wear suitable breathing protection because wood dust can be harmful.

Drilling metal

Select the correct gear, set the drill to drilling mode, and use bits rated for the metal type being drilled. Mark the hole location before starting, and use cutting fluid or lubricant to improve cutting and bit life. Apply only moderate pressure and allow the bit and workpiece to cool before touching them.

Keep the motor vents clear, since metal dust can damage the tool. If the drill becomes excessively hot, stop and let it cool before continuing.

Belt clip

The belt clip can be fitted into the housing groove and secured with a screw. It is meant for temporary hanging between tasks and can be removed by loosening the screw.

Cleaning and maintenance

Disconnect the battery before cleaning or maintaining the drill, and disconnect the charger from mains power before servicing it. Neither the drill nor the charger has user-serviceable internal parts, so repairs should be handled by an authorized service center if the tool does not operate as expected.

Check fixing screws regularly and inspect the supply cord and extension cords for wear or damage. Keep the drill clean with a soft brush or dry cloth, and clear the ventilation openings with clean, dry compressed air when available. For the outer casing, use a soft damp cloth with mild detergent. Avoid alcohol, petrol, strong cleaners, and caustic products.

Light lubrication of moving parts at regular intervals helps keep the drill operating smoothly. Dispose of worn-out tools and batteries according to local rules rather than placing them in household waste.

Troubleshooting

If the drill will not start, check that the battery is seated correctly, charged properly, and suitable for the MP20V system. The tool may also refuse to start if the switch contacts are damaged, the battery is worn out, or the tool is overloaded. Let the drill cool down after overload before restarting.

If performance is slow, the most common causes are excessive pressure on the workpiece, a low battery, or battery wear. Reduced output, noisy operation, rattling, or overheating often point to internal wear, blocked vents, or a worn chuck. A qualified technician should handle internal repairs.

If the drill overheats, stop work immediately, let it cool, and make sure the motor vents are clear. Slow, strained operation usually improves when the tool is allowed to work at its own pace instead of being forced.
