A dead electric chainsaw can turn a quick branch-cutting job into an afternoon of staring at a silent trigger. The battery may show a charge, the outlet may run another machine, and the chain may look normal. Yet the Bauer saw sits still like a locked door.
Start with the power path and the safety controls. On the Bauer 20V cordless 10-inch chainsaw, the most common causes are a loose battery, an empty or failed battery, an overload trip, or internal wear. On the Bauer 14.5-amp corded 16-inch chainsaw, check the chain-brake lever, trigger lockout, outlet, GFCI, breaker, and extension cord before suspecting the motor.

Disconnect the Power Before Touching the Chain
Remove the battery from a cordless Bauer chainsaw. Unplug a corded model from the wall. Do this before checking chain movement, bar fit, sprocket condition, or packed sawdust under the side cover.
Wear heavy gloves when moving the chain by hand. Even a dull cutter can open skin with little pressure. Never test a switch while your hand rests near the bar.
Stop work at once when a battery is swollen, cracked, leaking, unusually hot, or giving off a sharp chemical smell. Place it away from dry leaves, fuel, paper, and sawdust. Do not open the battery case or bridge its contacts with metal.
Match the Symptom to the First Check
| What the Saw Does | Probable Cause | Check First |
|---|---|---|
| Completely silent | No power, loose battery, brake set, or lockout not pressed | Power supply and safety controls |
| Clicks but does not run | Weak battery, tight chain, jam, or failed switch | Battery swap and chain movement |
| Motor runs but chain stays still | Chain too tight, damaged bar, jammed sprocket, or gear fault | Chain tension and side-cover area |
| Runs until it enters wood | Overload, dull chain, weak battery, thin cord, or pinched bar | Chain edge, oil level, power supply, and cutting pressure |
| Stops after several cuts | Heat or overload protection | Release the trigger and let the saw cool |
Bauer 20V Cordless Chainsaw Not Turning On
The Bauer 20V cordless 10-inch chainsaw is Item 64940. Its manual lists four main reasons for a no-start condition: the battery is not seated, it is not charged, it has failed, or the saw has internal damage.
Remove and Reseat the Battery
Press the battery release and slide the pack out. Look into the battery slot with a flashlight. Wood chips, bark dust, and sticky sap can stop the pack before it reaches the electrical contacts.
Brush loose debris away with a dry nylon brush. Do not pour cleaner into the battery slot. Do not scrape the metal contacts with a screwdriver.
Slide the battery back into the saw. Press it firmly until the latch clicks. Pull lightly on the pack without pressing the release. It should remain locked in place.
Check the Battery Charge
Press the charge-gauge button on the battery. A low reading points to a simple charging problem. Place the battery on its Bauer charger and allow a full charge cycle.
Check that the charger is plugged into a live outlet. A failed outlet can make a good charger look dead. Test the outlet with a lamp or another small appliance.
A battery gauge can light even when an older pack can no longer supply enough current for the chainsaw motor. The fastest test is a known-good Bauer 20V battery. Fit that pack into the chainsaw and try the trigger again.
You can also place the suspect pack in another Bauer 20V machine. When the pack fails in both, the battery is the probable cause. When another pack runs the chainsaw, the saw itself is probably fine.
Let a Hot or Cold Battery Return to Room Temperature
A battery that has been sitting in summer sun, a hot vehicle, or freezing storage may refuse to charge or power the saw. Bring it into a dry room and allow its temperature to settle naturally.
Do not place the pack beside a heater. Do not put it in a refrigerator or freezer. Sudden temperature changes can create moisture around the contacts.
Reset the Overload Protection
The cordless Bauer saw has an internal circuit breaker for overload events. Heavy pressure against the log can stop the chain and trip this protection.
Release the trigger fully. Remove the battery and inspect the bar. Check for a pinched chain, packed debris, low oil, or a cutter stuck in the wood. Free the bar before placing the battery back into the saw.
Allow the motor and battery to cool when either feels hot. Refit the pack, hold the saw away from wood, and try the trigger. Let the chain reach full speed before starting the next cut.
Do not lean your full body weight into an electric chainsaw. Let the cutters pull themselves through the wood. Heavy pressure acts like a hand on a bicycle brake. It slows the chain, raises heat, and can trip the breaker again.
Press the Trigger Lockout Correctly
The Bauer cordless saw will not start from the trigger alone. Press the lockout, squeeze the trigger, and then release the lockout while holding the trigger.
Check whether the lockout button moves freely and springs back after release. Sawdust can gather around the button. Clean the outside with a dry brush while the battery is removed.
Never tape the lockout down. Never remove or bypass it. A chainsaw with a defeated lockout can start as soon as the trigger is touched.
Bauer Corded Electric Chainsaw Not Turning On
The Bauer 14.5-amp corded chainsaw is Item 57622. It has a 16-inch bar and runs from a 120-volt outlet. A dead start often comes from the chain brake or power cord rather than the motor.
Pull the Chain-Brake Lever Back
The corded Bauer saw will not run while its hand guard and chain-brake lever sit in the forward position. Pull the front hand guard back toward the handle until it reaches the normal operating position.
The lever should move with a firm action. Do not force it when it feels jammed. Remove the plug and inspect the outer area for packed wood chips or a cracked guard.
Try the saw only after the lever sits fully back. Press the trigger lockout first, then squeeze the trigger.
Test the Outlet and GFCI
Plug a lamp into the same outlet. When the lamp stays dark, check the breaker panel and any nearby GFCI receptacle. Outdoor outlets are often tied to a GFCI in a garage, bathroom, basement, or utility room.
Press the GFCI reset button. Reset a tripped breaker by moving it fully to the off position and then back on.
Do not keep resetting a breaker that trips each time the chainsaw starts. Repeated trips can point to an electrical fault, a damaged cord, a wet connection, or an overloaded circuit.
Check the Extension Cord
The 14.5-amp motor draws a heavy load. A thin or very long extension cord can cause a voltage drop. The motor may refuse to start, run weakly, or become hot.
The Bauer manual calls for a 14-gauge cord at 25 feet, a 12-gauge cord at 50 feet, and a 10-gauge cord at 75 feet for a load between 12.1 and 16 amps. The manual does not give a cord size for 100-foot or 150-foot runs in this amp range.
Use an outdoor-rated cord marked for outdoor service. Inspect the full length for cuts, crushed areas, melted insulation, bent blades, or a loose socket. Replace a damaged cord rather than wrapping a serious cut with tape.
Push the chainsaw plug fully into the extension cord. Secure the connection in the saw’s cord clip so pulling force does not separate the plugs during work.
Try a Shorter Cord
When the saw is silent on a long cord, test it with a shorter heavy-gauge cord in a dry area. Keep the bar clear of the floor and nearby objects.
A saw that runs on the short cord but fails on the long cord points to the cord, connection, or voltage drop. A saw that remains silent after the brake, lockout, outlet, and cord all pass their checks may have a failed switch, brush, wire, or motor.
What if the Motor Runs but the Chain Does Not Move?
This symptom is not the same as a dead saw. The motor sound proves that power is reaching part of the machine. The fault sits closer to the bar, chain, sprocket, or drive gears.
Check for an Overtight Chain
Remove the battery or unplug the saw. Put on gloves. Pull the chain away from the middle of the lower bar rail and release it.
The chain should snap back against the bar. Its drive links should stay inside the groove. You should still be able to slide the chain around the bar by hand.
A chain that will not move by hand is too tight or jammed. Loosen the tension and test it again. A chain that hangs below the lower rail is too loose.
New chains stretch during early use. Check tension often during the first few cutting sessions. Let a hot chain cool before making the final setting because metal contracts as it cools.
Look for Packed Sawdust
Remove the power. Take off the side cover only when you are comfortable with bar and chain assembly. Packed chips can fill the sprocket area and stop the chain.
Brush away sawdust and bark. Check that every drive link sits inside the bar groove. Inspect the sprocket teeth for cracks, heavy wear, or lodged debris.
Do not press the trigger with the side cover removed. Do not place a battery in the saw until the bar, chain, support plate, cover, and tension parts are fitted correctly.
Inspect the Bar and Chain
A bent bar can pinch the drive links. A damaged chain can bind at one point as it travels around the nose. Move the chain slowly by hand and feel for a tight spot.
Replace a chain with cracked links, stiff joints, damaged rivets, or bent drive links. Replace a bar that is bent, cracked, or badly worn along its rails.
When the chain and bar move freely but the motor still cannot drive them, the gear train or drive sprocket may have failed. This repair belongs with a qualified technician.
Check the Bar-Oil Level
Low oil does not always cause a dead start, but it can create enough heat and drag to stop the saw during a cut. Both Bauer chainsaws have automatic oiling and need bar-and-chain oil in the reservoir.
Check the oil window before cutting. Refill the tank when the level is low. Wipe dirt away from the cap before opening it so grit does not fall inside.
A dry chain may squeal, smoke, or turn dark near the drive links. The bar may feel very hot. Stop at once when this happens.
After adding oil, hold the running bar near a clean piece of cardboard or pale wood. A light line of oil should appear after a brief run. Keep the bar clear of your body during this check.
Signs That the Saw Needs Shop Work
Stop home checks when you notice a burned smell, smoke from the housing, heavy sparking, melted plastic, a hot plug, a cracked battery case, or a trigger that sticks in the on position.
A corded model may need a new switch, carbon brushes, internal wire, or motor. A cordless model may have a failed trigger unit, control board, motor, or gear case.
Opening the housing can expose live electrical parts, sharp springs, and tightly fitted wires. It can also make a warranty claim harder. Ask for a repair quote before buying internal parts.
Is the Bauer Chainsaw Worth Repairing?
Compare the repair cost with the price of a replacement saw. In July 2026, Harbor Freight listed the Bauer 20V cordless 10-inch chainsaw at $84.99 for the bare saw. The Bauer 14.5-amp corded 16-inch model was listed at $74.99.
| Fault | Repair Choice |
|---|---|
| Battery not seated | Clean and refit it |
| Dead battery | Replace the pack when the saw works with another one |
| Bad extension cord | Replace it with the correct gauge |
| Chain too tight or jammed | Reset tension and clean the drive area |
| Worn chain or bar | Replace the cutting parts |
| Failed switch or carbon brushes | Get a quote and compare it with replacement cost |
| Failed motor, gears, or cracked housing | Replacement is often the cheaper path |
Harbor Freight lists a 90-day warranty for both current Bauer chainsaw pages. Keep the receipt. A recent purchase may qualify for help before you spend money on parts.

Frequently Asked Questions
Why is my Bauer electric chainsaw completely silent?
On the cordless model, check battery seating, charge, pack condition, and trigger lockout. On the corded model, pull the chain-brake lever back, press the lockout, test the outlet, reset the GFCI, and inspect the extension cord.
Why does my Bauer chainsaw stop inside the log?
The saw may be overloaded. A dull chain, heavy pressure, low oil, a weak battery, a thin extension cord, or wood pinching the bar can stop the motor. Release the trigger, remove power, and find the cause before restarting.
Why does the battery show full but the saw will not start?
An old battery may show charge but fail under a heavy motor load. Test another Bauer 20V battery in the saw. Test the suspect battery in another Bauer 20V machine.
Can I use a Bauer 5Ah battery in the 20V chainsaw?
Yes. Bauer’s current 5Ah battery is sold for its 20V family and gives more run time than a small pack. The battery must latch firmly and remain free from damage.
Can I bypass the trigger lockout?
No. The lockout blocks accidental starts. A damaged lockout or trigger should be repaired rather than taped, removed, or bypassed.
What extension cord should I use with the 14.5-amp Bauer chainsaw?
Use at least 14 gauge for 25 feet, 12 gauge for 50 feet, or 10 gauge for 75 feet. The cord must be rated for outdoor service and remain dry and free from damage.
Best Fix Order
For the Bauer 20V cordless chainsaw, remove and reseat the battery, charge it, try another battery, clean the battery slot, reset an overload by releasing the trigger, and check the chain for tightness or a jam.
For the Bauer 14.5-amp corded chainsaw, pull the chain-brake lever back, press the trigger lockout, test the outlet, reset the GFCI, inspect the cord, and try a shorter heavy-gauge extension cord.
When the motor runs but the chain stays still, remove power and check chain tension, bar condition, sprocket movement, and packed sawdust. When the saw remains silent with a known-good power supply, the switch, wiring, motor, or brake linkage may need shop work.
Begin with the simple checks. A silent Bauer chainsaw often needs a seated battery, a reset outlet, or a brake lever pulled back. Those small fixes can wake the saw as quickly as turning the right key in a stubborn lock.
