The safety instructions in this section are to protect the user from serious personal injury.

nRemove the battery pack before you do any work on the chain saw.

nRemove the hex key from the storage area and use it to remove the chain cover screw, washer and chain cover from the chain saw.

nRemove the bar and chain from the mounting surface.

nRemove the old chain from the bar.

nLay out the new saw chain in a loop and straighten any kinks. The cutters should face in the direction of chain rotation. If they face the opposite direction, turn the loop over.

nPlace the chain drive links into the bar groove. Position the chain so there is a loop at the back of the bar. Hold the chain in position on the bar and place the loop around the sprocket of the chain saw. Fit the bar flush against the mounting surface so that the bar stud is in the long slot of the bar.

NOTE: When placing the bar on the bar stud, assure that the adjusting pin is in the chain tension pin hole.

Another significant technology incorporated into the Ryobi P540 is its Turbo Boost feature. This feature enables a temporary increase in power, allowing users to handle more challenging tasks with ease. When extra power is needed, simply activate the Turbo Boost to unleash a concentrated burst of airflow for efficient debris removal.

The blower’s design includes a streamlined nozzle which enhances airflow efficiency, directing air precisely where it is needed. This design results in a more effective blowing pattern, ensuring that no debris is left behind. Additionally, the unit is designed for easy storage, with a compact design allowing it to fit neatly in sheds or garages without taking up too much space.

Durability is another key characteristic of the Ryobi P540. Built with high-quality materials, this blower is designed to withstand the rigors of outdoor use while providing consistent performance.
