Yes, it is safe to move your grandfather clock to perform maintenance on your home in the space around the clock. The below steps offer rough guideline to help you move your grandfather clock safely: Remove the weights. Look at the bottom of the weights for right, center, and left markings as they are different weights and must be reinstalled in the same order. This is done as you are facing the front of the clock. Unhook the pendulum being careful not to damage the suspension spring at the top. Move the clock to desired space. When you replace the clock, make sure that the clock is NOT leaning forward. Usually there are leg levelers on the bottom of the clock to ensure proper standing. It is important to reinstall the clock to the manufacturers instructions that came with the clock, so take particular care during this step and consult your manual. Re-hang the pendulum and weights. Once in place, move the pendulum close to the side of the clock and release. When the pendulum slows down to its normal swing it should be running evenly with an even tic-toc sound. Most grandfather clocks manufactured after 1983 have a self-adjusting feature that allows you to move the clock and restart it easily and have it run evenly.
