They should adjust themselves every time you back up ans stop. Try backing up and applying the parking brake and see if that adjusts them. If not you will need to adjust them manually. There should be a slot on the brake drum backing plate underneath the car on the backside of the drum assembly. It should have a rubber plug. Remove the plug and with a drum brake adjustment tool, turn the star wheel to tighten the brake shoes against the drum. Tighten it until the wheel can no longer be turned. Now back it off until the wheel just turns freely.
The parking brake is designed to automatically self-adjust every time it is applied. However, if the mechanism has become frozen or stuck, it can be adjusted manually by a mechanic or a knowledgeable amateur.

how do you adjust parking brake

Volvos have automatic slack adjusters, which are dangerous to manually adjust. If your brakes are so far out of whack you think you might have to screw with the slack adjusters, you really need a brake job. Usually the slack adjuster must be backed off before you can remount the brake drums. The do have to be adjusted manually to get at least some drag on the drums before you set them automatically.
