Earlier than beginning, make sure that the chainsaw is turned off, the chain brake is engaged, and the spark plug is disconnected.
2. Find the Tensioning Screw
Determine the tensioning screw positioned on the facet of the chainsaw, usually close to the information bar mount.
3. Loosen the Lock Nut
Utilizing a wrench, rigorously loosen the lock nut that secures the tensioning screw.
4. Modify the Chain Pressure
Flip the tensioning screw clockwise to tighten the chain or counterclockwise to loosen it. Whereas adjusting, maintain the information bar nostril up off the bottom and slowly rotate the chain by hand to make sure that it strikes easily. The best rigidity is when the chain is comfortable however not so tight that it binds towards the information bar.
To realize optimum chain rigidity, observe these pointers:
| Chain Situation | Pressure Verify | 
|---|---|
| New Chain | Tighten till the chain simply touches the underside of the information bar slot. | 
| Used Chain | Tighten till the chain has 1/4″ to three/8″ of play on the midpoint between the information bar and the tip of the chain. | 
5. Retighten the Lock Nut
As soon as the specified chain rigidity is achieved, securely tighten the lock nut utilizing the wrench.
6. Closing Checks and Reconnect
Be sure that the chain brake is disengaged and the spark plug is reconnected. Begin the chainsaw and run it briefly to examine the chain rigidity. Make any obligatory changes if wanted.
Utilizing the Chain Tensioning Screw
The chain tensioning screw is a bolt positioned on the facet of the chainsaw’s engine housing. It’s used to regulate the chain rigidity by tightening or loosening the screw. To tighten the chain utilizing the chain tensioning screw, observe these steps:
