Craftsman CMCHTS820 Cordless Hedge Trimmer Manual

Introduction

The Craftsman CMCHTS820 Cordless Hedge Trimmer is a battery-powered outdoor tool designed for trimming shrubs, hedges, ornamental bushes, and light branches without the restrictions of a power cord. Its 20V MAX battery platform provides portable power for routine landscape maintenance, while the 22-inch dual-action blade supports efficient, controlled cutting across broad hedge surfaces.

This cordless hedge trimmer combines a large blade gap with a rated cutting capacity of up to 3/4 inch for typical hedge-trimming work. A built-in power saw feature is intended for branches up to 1-1/2 inches thick, helping reduce the need to switch tools when isolated larger branches appear. The full bale handle supports multiple hand positions and improves maneuverability when shaping the top, sides, and corners of a hedge.

The tool is suitable for homeowners, property managers, and landscape maintenance users who need convenient seasonal trimming. It works well for shaping overgrown hedges, maintaining privacy screens, and cutting back new growth around walkways and fences. The tool-only version requires a compatible CRAFTSMAN V20 battery and charger; kit versions may include a battery, charger, and blade cover.

Before operating the Craftsman CMCHTS820 Cordless Hedge Trimmer, read the supplied instruction manual, inspect the blade area, and wear eye, hearing, hand, and foot protection. Remove the battery whenever the tool is transported, adjusted, cleaned, or stored.

Use the trimmer primarily for hedge growth within the standard 3/4-inch capacity.

How to Set Up the Craftsman CMCHTS820 Cordless Hedge Trimmer

Inspect the package: Confirm that the trimmer, blade cover, battery, and charger are present when supplied as a kit. Do not operate the tool if the blade, housing, trigger, or handle is damaged.
Charge the battery: Place the compatible V20 lithium-ion battery on its charger and allow charging to finish according to the charger indicators and instructions.
Prepare the work area: Remove stones, wire, toys, and other objects from the hedge. Check for hidden fencing, cables, and thick woody growth.
Remove the blade cover: Keep hands away from the cutting teeth and remove the cover only when ready to work.
Install the battery: Slide the charged battery into the tool until it locks securely. Pull gently on the battery to confirm it is seated.
Start the trimmer: Hold the bale handle and operate the safety switch and trigger as described in the instruction manual. The motor should start smoothly without unusual noise.
Test briefly: Release the trigger and remove the battery if the blade does not stop, the trigger sticks, or excessive vibration occurs.

The CMCHTS820 does not use wireless pairing or Bluetooth connectivity. Never bypass safety switches, operate with one hand, or use the tool in rain or near standing water. Wear eye protection, gloves, hearing protection, long trousers, and sturdy non-slip footwear.

Craftsman CMCHTS820 Troubleshooting Guide

Tool does not start: Confirm that the battery is charged and fully latched. Remove and reinstall it, then check that the safety switch and trigger are being operated correctly.
Motor stops during cutting: Release the trigger, remove the battery, and inspect the blade for jammed branches. Reduce cutting pressure and work within the rated capacity.
Blade moves slowly: Recharge the battery, clear debris, and inspect the blade for resin or buildup. A heavily worn or damaged blade should be serviced rather than sharpened improperly.
Excessive vibration: Stop immediately and check for bent, loose, cracked, or obstructed blade components. Do not continue using the trimmer until the cause is corrected.
Poor cutting quality: Use steady sweeping movements and approach branches squarely. Clean the blade after use and follow the manual’s lubrication guidance.
Battery will not charge: Check that the charger is connected correctly, allow a hot or cold battery to return to a suitable temperature, and test with the correct V20 charger.

The available documentation does not identify a universal numeric error-code system for this model. If the trimmer remains inoperative, do not disassemble the motor or battery. Record the model and serial information and contact CRAFTSMAN customer support or an authorized service provider. CRAFTSMAN customer service can be reached at 888-331-4569; warranty coverage and service conditions should be confirmed for the specific purchase and model version.

Preventive maintenance includes removing the battery before cleaning, brushing debris from the blade and housing, applying approved blade lubricant as directed, inspecting fasteners, and storing the tool with the blade cover installed.

Pros and Cons of the Craftsman CMCHTS820

Advantages

Cordless convenience: Battery power eliminates extension cords and makes trimming easier around fences, trees, and garden beds.
Long cutting reach: The 22-inch dual-action blade covers more hedge surface with each pass than many compact residential trimmers.
Useful capacity: The 3/4-inch cutting capacity suits common hedge growth, while the power saw area handles occasional branches up to 1-1/2 inches.
Control: The full bale handle supports different hand positions for vertical, horizontal, and angled cuts.
Battery compatibility: Existing V20 battery owners may be able to use their compatible batteries and chargers across the platform.

Limitations

Battery dependence: Runtime varies with battery capacity, branch thickness, temperature, and cutting technique.
Not for heavy clearing: Continuous cutting of thick, dry, or woody branches is better handled by a dedicated saw or heavier-duty tool.
Brushed motor: Compared with brushless models, the brushed motor may offer less efficiency and may require more maintenance over extended use.
Package differences: Tool-only and kit versions have different included accessories, so verify the package contents before setup.

The Craftsman CMCHTS820 Cordless Hedge Trimmer is best suited to homeowners and light-duty landscape users who value portability and straightforward hedge maintenance. Users managing large commercial properties, very tall hedges, or frequent heavy branches may need a longer-reach, brushless, or higher-capacity professional model.

Faqs

How do I set up the craftsman CMCHTS820 Cordless Hedge Trimmer for the first time?

Before setup, inspect the trimmer, blade guard, battery, and controls for damage. Charge a compatible CRAFTSMAN V20 lithium-ion battery using an approved CRAFTSMAN charger, then remove the blade cover. With the trigger released, slide the battery into the tool until it locks securely. Hold the auxiliary handle and rear handle firmly, press the safety switch, and squeeze the trigger. Keep the blade away from people, pets, wiring, and hard objects during startup.

Which battery and charger work with the craftsman CMCHTS820 Cordless Hedge Trimmer?

The craftsman CMCHTS820 Cordless Hedge Trimmer is designed for the CRAFTSMAN V20 battery platform. Compatible battery options listed for this model include CMCB201, CMCB2011, CMCB202, and CMCB204, while compatible chargers include CMCB100, CMCB102, and CMCB104. Confirm the model number printed on your battery and charger before use. Do not force an incompatible pack into the tool or use a damaged, swollen, or leaking battery.

Why is my craftsman CMCHTS820 Cordless Hedge Trimmer not starting?

If the craftsman CMCHTS820 Cordless Hedge Trimmer does not start, remove the battery and reinstall it firmly until the release buttons engage. Check that the battery is charged and that the blade is not jammed by leaves or branches. Make sure you are pressing the safety switch before squeezing the trigger. If the motor still remains silent, inspect the contacts for dirt and test a known-good compatible battery. Stop using the tool if the trigger or housing is damaged.

How can I prevent the craftsman CMCHTS820 Cordless Hedge Trimmer from cutting out during use?

Repeated shutdowns usually result from an overloaded blade, a low battery, or excessive pressure. Use the craftsman CMCHTS820 Cordless Hedge Trimmer on branches within its rated cutting capacity, allowing the dual-action blade to work instead of forcing it. Trim thick growth gradually, keep the blade clear, and use a fully charged battery. If the motor stops, release the trigger, remove the battery, and clear the obstruction only with the blade completely stationary.

What is the best way to use the craftsman CMCHTS820 Cordless Hedge Trimmer for cleaner cuts?

Start with the lower branches and work upward, using smooth sweeping motions rather than repeatedly stabbing into the hedge. Keep the 22-inch dual-action blade parallel to the hedge for even shaping, and slightly angle the top so sunlight can reach lower growth. Avoid cutting wet material when possible because it can clog the blade. For larger branches, use the designated power-saw section only as instructed in the manual and never twist the trimmer while cutting.

Can the craftsman CMCHTS820 Cordless Hedge Trimmer cut thick branches?

The craftsman CMCHTS820 Cordless Hedge Trimmer is intended primarily for hedge trimming, with a general cutting capacity of up to three-quarters of an inch. Its power-saw feature is designed for selected branches up to approximately one and one-half inches, but actual performance depends on wood type, age, and condition. Do not force oversized, hardened, or embedded branches into the blade. Use a suitable pruning saw for material beyond the tool’s capacity.

How should I clean and maintain the craftsman CMCHTS820 Cordless Hedge Trimmer?

Remove the battery before cleaning, clearing debris, or performing maintenance on the craftsman CMCHTS820 Cordless Hedge Trimmer. Brush leaves and clipped material from the blade housing and ventilation openings, then wipe the tool with a dry or slightly damp cloth. Do not spray it with water or use solvents. After cleaning, apply an appropriate light tool lubricant to the blade if specified by the manual, replace the blade cover, and store the trimmer in a dry location.

What should I do if the craftsman CMCHTS820 Cordless Hedge Trimmer blade jams or becomes dull?

Release the trigger immediately and wait until the blade stops completely. Remove the battery before attempting to clear twigs, vines, or packed leaves, and use a stick or brush rather than your hands. Inspect the blade for bent teeth, cracks, or severe wear. Lightly lubricate it as recommended, but do not operate the trimmer if the blade is damaged. A persistently dull or damaged blade should be serviced or replaced through an authorized repair provider.
