User Manual for WEN 20716 20V Max Cordless Dethatcher and Scarifier

Quick guide from the manual

The WEN 20716 is a 20V cordless dethatcher and scarifier designed to improve lawn health by removing thatch and moss. Important: The unit requires two batteries to operate. For best results, use batteries with a capacity of 4Ah or higher. Always remove the safety key and batteries before performing any maintenance, cleaning, or adjustments.

Assembly and adjustments

Follow these steps to prepare your tool for use:

• Handle Assembly: Attach the lower handles to the body using the angle adjustment cam knobs. Install the middle handle onto the lower handles, then attach the upper handle to the middle handle using the provided cam knobs, washers, and bolts. Secure the power cord with the provided cable clips.
• Thatch Bag Installation: Lift the thatch bag cover and secure the bag to the mounting hooks on the back of the body. Clip the sides of the bag onto the thatch bag rack frame.
• Depth Adjustment: Move the depth adjustment lever to the right and down to select the desired gear. Negative depth settings indicate the blades are digging into the ground. Use position 1 for transport or thin thatch, and positions 4-5 for scarifying.

Operation

To power on the machine:

1. Install the batteries and connect the safety key.
2. Press the safety lock button on the side of the upper handle.
3. While holding the safety lock, pull the switch handle towards the upper handle.
4. Release the safety lock button and hold the switch handle against the upper handle to continue operation.

To power off, release the switch handle and remove the batteries and safety key.

Maintenance and blade replacement

Regular maintenance ensures longevity:

• Cleaning: Clean the underside of the tine guard and motor housing after each use using a scrubbing brush and a soft cloth with mild soap. Never use a water hose.
• Blade Replacement: The unit comes with two blades. To change them, unscrew the hex screws on the bottom of the body, remove the blade bracket, and swap the blade. Ensure the square end of the blade shaft aligns with the square hole of the output gear.

Overload protection

If the machine stops due to overload (e.g., build-up of materials or too much resistance), switch the machine off, remove it from the power source, and clear the obstruction before restarting.
