CRAFTSMAN CMCCS320B Cordless Pruning Chainsaw Manual

The craftsman CMCCS320B Cordless Pruning Chainsaw is a compact V20 cordless chainsaw designed for pruning branches, cutting small limbs, and maintaining trees around the home. Its 6-inch bar and chain provide cutting capacity for branches up to 4 inches in diameter, making it suitable for controlled pruning rather than heavy tree felling.

This tool-only model operates on the CRAFTSMAN V20 battery platform. The battery and charger are sold separately, so users should confirm that they have a compatible V20 lithium-ion battery before beginning setup. When paired with a fully charged battery, the saw can make up to 85 cuts per charge under stated test conditions.

An integrated tip guard helps improve control during upper cuts, while the bolt-lock chain-tensioning system helps secure the guide bar and maintain proper chain adjustment. A storage sheath protects the chain between jobs and includes an onboard wrench holder for convenient storage.

The chainsaw is intended for homeowners, gardeners, landscapers, and property-maintenance users who need a portable pruning tool without fuel, engine exhaust, or an extension cord. It works well for removing deadwood, trimming small branches, and preparing cut limbs for disposal. Wear eye, hearing, hand, leg, and foot protection, and never use the saw above shoulder height or near people and pets.

How to Set Up the CRAFTSMAN CMCCS320B

Inspect the saw, guide bar, chain, chain cover, trigger, lock-off button, and battery compartment for damage.
Charge a compatible CRAFTSMAN V20 battery using the correct charger. Do not install a damaged, wet, or swollen battery.
With the battery removed, verify that the chain is correctly positioned in the guide-bar groove and follows the directional marks on the bar.
Check chain tension according to the instruction manual. The chain should remain engaged with the bar groove while still moving freely by hand when the battery is removed and suitable gloves are worn.
Confirm that the guide-bar cover and bolt-lock assembly are secure. Do not operate the saw if the bar, chain, or locking hardware is loose.
Remove the storage sheath only when ready to cut, then insert the charged battery until it locks into place.
To operate, press the lock-off control and then squeeze the main trigger. Release the trigger to stop the chain.

There is no Bluetooth pairing or wireless connectivity process for this model. Before cutting, clear the work area, establish stable footing, keep both hands on the saw, and plan where the branch will fall. Never start the tool while the chain is touching wood.

CRAFTSMAN CMCCS320B Troubleshooting Guide

Saw will not start: Remove and reinstall the battery, confirm that it is charged, and fully press the lock-off control before squeezing the trigger.
Saw stops during use: Recharge the battery and reduce cutting pressure. Forcing the chain into wood can overload the motor and activate protective shutdown.
Battery will not charge: Make sure the battery is fully seated in the charger, the charger is connected to a working outlet, and the ambient temperature is between 40°F and 104°F.
Chain or bar overheats: Stop cutting, allow the tool to cool, clean the bar groove and oiling area, and inspect chain tension and sharpness.
Chain rotates poorly: Remove the battery before inspection. Check for sawdust buildup, excessive tension, a damaged chain, or a blocked guide-bar groove.
Rough or slow cuts: Sharpen or replace the chain and avoid twisting the bar while cutting.
Oil-related concern: Stop operation and inspect the guide bar, chain, and lubrication system before continuing. Follow the manual’s approved lubrication instructions.

This model does not use a broad electronic error-code display, so symptoms are generally addressed through battery, trigger, overload, chain, and maintenance checks. For parts, manuals, service-center information, or warranty assistance, use the official CRAFTSMAN support and manuals pages or call CRAFTSMAN customer service at 1-888-331-4569. Keep the model and type information available when requesting help.

Pros and Cons of the CRAFTSMAN CMCCS320B

Advantages

Portable cordless design: The V20 battery system eliminates gasoline mixing, engine exhaust, and extension cords.
Compact pruning format: The 6-inch bar is easier to control for small branches than a larger homeowner chainsaw.
Useful cutting capacity: Its stated capacity of up to 4 inches suits routine pruning and light limb removal.
Helpful control features: The integrated tip guard and bolt-lock chain tensioning support controlled operation and secure bar clamping.
Convenient storage: The included sheath protects the chain and stores the adjustment wrench.

Limitations

Tool-only package: Users without a compatible V20 battery and charger must obtain those components separately.
Limited bar length: A 6-inch bar is intended for pruning and small limbs, not large logs or tree felling.
Brushed motor: Compared with some newer brushless cordless saws, this design may offer less motor efficiency and runtime consistency.
Battery-dependent runtime: Actual cuts per charge vary with battery size, wood hardness, chain condition, and technique.

The craftsman CMCCS320B Cordless Pruning Chainsaw best suits homeowners and gardeners who already use CRAFTSMAN V20 tools and need a compact branch saw. Users requiring frequent large-limb cutting, long continuous runtime, or professional forestry performance should choose a larger, purpose-built chainsaw.

Faqs

How do I set up the Craftsman CMCCS320B Cordless Pruning Chainsaw for the first time?

Inspect the bar, chain, sprocket cover, and chain tension before inserting the battery. Confirm that the chain is installed in the correct cutting direction and is properly tensioned according to the manual. Charge a compatible Craftsman V20 lithium-ion battery separately, slide it into the saw until it locks, remove the storage sheath, and test the trigger and safety switch briefly without contacting wood. Wear eye, hearing, hand, leg, and slip-resistant foot protection before cutting.

Which battery and charger work with the Craftsman CMCCS320B Cordless Pruning Chainsaw?

The Craftsman CMCCS320B uses the Craftsman V20 lithium-ion battery platform, and the tool-only package does not include a battery or charger. Use a compatible V20 battery pack and Craftsman V20 charger listed in the instruction manual rather than attempting to adapt another voltage system. Inspect the battery terminals for dirt or damage, charge the pack fully, and remove it from the saw before transporting, cleaning, or changing the chain.

What should I do if the Craftsman CMCCS320B Cordless Pruning Chainsaw will not start?

First remove and reinstall the V20 battery, ensuring it is charged and fully latched. Check that the storage sheath is removed and that the safety switch and trigger are being operated in the correct sequence. If the chain is jammed, disconnect the battery before inspecting the bar and chain. Clear packed wood chips only with a brush or suitable tool. If the saw still does not run, stop using it and arrange qualified service rather than bypassing safety controls.

How do I fix a loose chain on the Craftsman CMCCS320B Cordless Pruning Chainsaw?

Remove the battery and place the saw on a firm, level surface before adjusting the chain. Loosen the sprocket cover enough for the bar to move, then use the supplied wrench and tensioning mechanism to tighten the chain gradually. The chain should remain seated in the bar groove while still moving by hand with protective gloves. Retighten the cover securely, rotate the chain manually to check for binding, and recheck tension after the chain cools from use.

What branches can the Craftsman CMCCS320B Cordless Pruning Chainsaw cut?

The Craftsman CMCCS320B has a 6-inch bar and chain with a stated cutting capacity of up to 4 inches, making it intended for pruning and small-limb work rather than large logs or felling trees. Measure the branch and avoid forcing the saw through material beyond its capacity. Support the branch when possible, plan where it will fall, and watch for springback, hidden tension, nails, wire, and other objects that can damage the chain.

How can I get longer battery runtime from the Craftsman CMCCS320B Cordless Pruning Chainsaw?

Use a sharp, correctly tensioned chain and let the chain do the cutting instead of pressing hard. Make clean cuts on suitable branches, avoid repeatedly stalling the motor, and keep the bar groove and sprocket area free of chips. Begin with a fully charged V20 battery and allow a hot battery or tool to cool before continuing. The advertised cutting count is an estimate and varies with branch diameter, wood type, chain condition, and technique.

How often should I maintain the Craftsman CMCCS320B Cordless Pruning Chainsaw?

Perform a quick inspection before every use. Check chain tension, cutting direction, bar condition, fasteners, battery contacts, and the safety controls. After cutting, remove the battery and brush away sawdust and chips, especially around the sprocket cover and bar groove. Sharpen or replace a dull, damaged, or stretched chain promptly. For replacement parts, the manual identifies the CMZCSC06 6-inch chain and CMZCSB06 6-inch bar; use only correctly rated components.

Why does the Craftsman CMCCS320B Cordless Pruning Chainsaw cut slowly or produce smoke?

Slow cutting, excessive vibration, or smoke usually indicates a dull or damaged chain, incorrect tension, a blocked bar groove, or excessive pressure. Stop immediately, remove the battery, and let the saw cool before checking it. Clean the bar and sprocket area, verify that the chain moves freely, and sharpen or replace the chain if its cutters are worn. Never continue cutting with smoke, a burning smell, binding, or visible damage; seek qualified service if the problem remains.
