Removing and Cleaning the Chassis’s Air Filter

1Unscrew the screws at the top and bottom of the air filter with a flathead screwdriver.

2Hold the air filter at the left-rear by its upper and lower edges, pull part of it out of the chassis, put one hand underneath the air filter to hold it, and pull it out slowly along the guides.

c CAUTION: Because the air filter is rather long, you should hold its front end with one hand, and bear its weight by putting another hand underneath it when sliding the air filter out of the chassis.

3Rather than taking the air filter mesh out, directly wash the air filter after removing it from the chassis, allow it to air dry, and insert it back into the chassis.
