The chain tension may be too tight.

Easy fix, just loosen the bar-retaining nuts and rotate the tensioning screw counterclockwise to the correct tension. Then tighten the nuts back up.

Internal combustion engines can seize up when poor lubrication causes the piston to overheat, expand and come into contact with the cylinder. Seizure affects both 4-stroke and 2-stroke internal combustion engines, and not just in cars, motorcycles and scooters, but in gardening tools too.
Chain Brake: Located on the top handle of the chainsaw, the chain brake is used to stop the chainsaw chain from rotating around the bar. There are two ways to engage the chain brake: by pushing the handle forward, or by force of inertia that occur when the saw kicks back.
The ignition coil needs to be replaced.

The ignition coil is the device that sends voltage to the spark plug, creating a spark that ignites the fuel and turns on the chainsaw. If the engine is not turning on, then the coil may have become defective, which can happen over time with repeated use.

The most common cause of a chainsaw that won`t cut properly is a dull cutting chain. Try sharpening or replacing the chain. Need help finding your model number? The chain may not have the proper amount of tension.
The chain brake is principally operated by the top-hand guard being pushed forward to engage the brake, and pulled back to disengage. The spring-loaded action allows powerful braking under emergency conditions and can halt a chain under full power in a fraction of a second.
When engaged, the chain brake stops the chain from rotating around the saw`s guide bar. When using a chainsaw, you should always start it with the chain brake engaged so the chain does not move.
The chainsaw chain should feel snug but still pull freely.

Can’t re-install side cover after chain replacement.
ANSWER : Either the cover was removed with the brake engaged, OR the brake was “tripped” while the cover was off the saw.
Clamp the cover in a vise being careful to stay on flat surfaces of the cover (use wooden blocks if needed) and pull the brake lever back to the “OFF” position. It’s a strong spring so pull hard in the direction that would be towards the rear of the saw if the cover were installed.
Hope this helps.

I just started up my new 16″ Homelite and the engine starts, but the mechanism that powers the chainsaw isn’t rotating… any suggestions?
ANSWER : The engine needs to be accelerated to make the chain turn. The chain should not be so tight on the bar that you can’t turn it by hand. Make sure the chain brake is off by pulling back on the brake paddle which has a ‘toggle’ effect–it should snap over to the new position. If still having problems, it is time to return for warranty exchange or repair. Hope this helps!

Just getting started with a new RCS1835. The motor goes but the chain isn’t engaged. Is there another brake I need to release?
ANSWER : The plastic safety kick back may be engaged. 1) unplug the saw. 2) push the kick back safety ahead then pull it back ( it is the guard in front of the handle)
Now if your electric motor is turning, but the chain sproket is not, it may well be the clutch. Tap it with a small hammer, make sure it is free and not hanging up.

Husky 435 chain brake is stuck in “locked” position with clutch cover off. How do I release the brake, so the cover will fit over the flywheel?
ANSWER : Hi, grab the cover in a vise in the same place the bar nuts tighten up to. Then pull the chainbrake lever back towards where the handle bar would normally be until it clicks and locks back. This will require a bit of force. Then refit the cover as normal. Hope this helps, regards Phil.
