Hi,

You have a beautiful spruce there, and removing photosynthetic tissue from the healthy tree might slow it's growth. If you need to limb the tree up for aesthetic or maintenance purposes, though, it will not be harmful to start trimming your spruce limbs that are near the base of the tree. You'll want to make sure you avoid pruning during summer and into fall. The sooner, the better. You'll also only remove 1/3 of the plants limbs, removing more than that in a single season will stress the tree. Keeping that in mind, it may take a few years to limb the tree up to the desired height, always keeping that "remove no more than 1/3 of the plant's tissue" rule in mind.

After limbing the tree up, you'll also be exposing the root zone of the tree to much more light and therefore it will become very important to apply mulch around the base to conserve moisture and keep the roots cooler. Be sure to leave a mulch-free area right around the trunk, start mulched area 3-6" away from the trunk.

Here is a helpful guide you can use for making the pruning cuts. You'll want to reference the section titled "Removing Large Branches on Evergreen Trees", use the 3 cut method and avoid cutting into the branch collar.
