the chain on my cs1500 spins but it just won't cut into the wood, it just sits there and smokes.
The primary cause of a spinning chain that smokes without penetrating the wood on an Oregon CS1500 is typically "reversed chain orientation." Because the CS150…

it feels underpowered and bogs down in cuts it used to handle fine, even with a fresh battery.
The DeWalt DCCS620B is a high-torque brushless tool, meaning if it's bogging down, the motor is likely fighting excessive physical resistance rather than suffe…
-
chain won't stop spinning when i let go of the trigger, it just keeps going slowly.
This phenomenon is known as "chain creep" or "ghosting." In the DeWalt DCCS620B, this occurs when the brushless motor controller continues to send a low-voltag…

-
the chain gets tight on one side of the bar but is loose on the other, can't get even tension
The bar has worn unevenly, a common issue called "rail height discrepancy." The guide bar's rails—the two edges the chain runs in—are not the same height. The …
-
my greenworks 40v saw only runs for like 2 minutes then dies, but the battery shows full charge on the charger
The most common cause is a faulty battery where one or more internal cells are weak or have failed. The battery's management system (BMS) reads a full charge i…

chainsaw makes a loud grinding noise and smells like burning plastic when i try to cut
The most common cause of a loud grinding noise and burning plastic smell on a Greenworks 40V chainsaw is the chain being installed backwards, so its cutting te…
-
new chain keeps coming loose and falling off my greenworks 16 inch chainsaw immediately after i tighten it
A chain that falls off immediately after tightening almost always indicates improper bar installation, preventing the tensioning mechanism from working. The ba…
-
my greenworks 40v chainsaw just quit in the middle of cutting and won't turn back on, battery is charged
The most common cause of a sudden shutdown on a charged Greenworks 40V chainsaw is the thermal overload protector engaging. This safety feature activates when …
-
it's smoking a lot more than it used to, really thick blue smoke even after it's warmed up.
Excessive blue smoke means the engine is burning too much oil. This is caused by an over-rich fuel/oil mixture or, less commonly, worn piston rings allowing cr…
-
my chainsaw is vibrating really badly, way more than it used to, makes my hands numb fast.
Excessive vibration indicates an imbalance in the rotating assembly. The most likely causes are a bent crankshaft, a failed anti-vibration mount, or a severely…

the chain brake on my 455 feels really stiff and is hard to engage by hand, sometimes it doesn't snap back off.
The brake band mechanism is binding due to sawdust, dirt, or a lack of lubrication. The pivot points for the brake lever and the band itself are gummed up. Thi…
-
it starts and runs for about 30 seconds then just shuts off like i hit the switch, and won't restart until it's cold again.
This is a classic symptom of a failing ignition coil. When the coil heats up, its internal winding fails and kills the spark. The engine shuts off abruptly. Wh…
-
the chain stops moving while i'm cutting even though the engine is still running at full throttle.
The clutch is slipping or the drive sprocket is worn out. This is a mechanical failure due to normal wear or a loose chain. A dull chain exacerbates this by in…
-
my 455 rancher is leaking bar oil all over my garage floor even when it's just sitting there not running.
Bar oil is siphoning from the tank through the oil pump. This is almost always caused by a missing or damaged oil tank vent. The vent is a small one-way valve …
-
chainsaw starts and idles but immediately dies when i give it throttle. acts like it's being choked.
The engine is running too lean at high speed. This is a fuel delivery or air intake issue. The most common cause is a clogged fuel filter in the tank or an inc…

my husqvarna 455 rancher ran fine last season, now it won't start at all, not even a pop. pull cord feels normal.
The engine is not getting fuel. Old, degraded fuel has clogged the carburetor jets and fuel lines. Ethanol-blend gas left in the system for over 30 days is the…
-
it starts and idles fine but bogs down and almost dies when i touch the throttle to cut.
The high-speed circuit in the carburetor is clogged or out of adjustment. It's getting enough fuel for low RPMs but not for the high-speed demand. Start with t…
-
my chainsaw won't start at all, not even a sputter, and i just filled it with fresh gas.
With fresh fuel ruled out, you're down to spark, compression, or a severe fuel delivery blockage. On these, a fouled spark plug or a dead ignition module are p…
-
the chain keeps coming loose no matter how much i tighten the nuts, like within minutes of cutting.
The bar nuts aren't the problem. The bar is likely worn unevenly, or the chain tensioning mechanism (the little pin that engages the bar) is broken or not seat…
-
it's getting harder and harder to pull the starter cord on my ms 170, feels really stiff.
That's usually a sign of low compression, or the starter mechanism itself is gummed up. On these, the recoil spring can also bind if it's misaligned. First, re…
-
saw runs okay but it's throwing way too much bar oil, coating everything in a slick mess.
The adjustable bar oil pump is set too high, or oiler plunger (if you have that model) is stuck partially engaged. On the MS 170, there's a small screw on the …
-
my ms 170 is leaking bar oil really bad, like a puddle under it when it sits, even with the cap tight.
Yeah, this one's common. The oil is leaking from the tank vent or a cracked oil line inside the saw. The MS 170's oiling system is gravity-fed, so if it's over…
-
chainsaw starts but the chain won't spin even when i give it throttle, just sits there.
The centrifugal clutch is either stuck engaged (rare) or, more likely, the drive sprocket or clutch drum is seized up from lack of lubrication or grime buildup…
