Operating Instructions for Hermle Keywound Mantel clocks with Hour Count and Half Hour Strike
Take the clock and key carefully from the packaging.
Carefully remove the protective packing such as foam rubber, corrugated paper, rubber bands, etc.
You will find these mainly where the hammers, and bells are located, inside the back of the clock.
Open the front door and remove the plastic safety bushing from the winding hole. Save the packing in case the clock needs to be mailed for service in the future.
Please wind your clock fully once a week for optimum performance (the clock will run a full week+ on one winding). To wind the clock, use the enclosed key. Turn the key clockwise until it stops. The left winder is for the striking, and the right winder powers the clock itself
If striking is not required, do not wind up the left winding post (some models have a strike shutoff lever located inside the back of the clock).
Move the minute hand (long hand) clockwise or counterclockwise to set the clock to the correct time. The clock will strike the number of each hour and will strike once on the half-hour.
If the clock is striking the wrong hour or is not pointing exactly to the hour positions, move the hour hand only (short hand) to point to the hour that the clock just struck.
To make the clock go slower or faster, turn the regulating screw that is shown in the upper left of the picture below.
To make the clock go faster: turn the screw at the very top left clockwise.
To make the clock go slower: turn the screw counterclockwise.
The screw is turned with a small flathead screwdriver.
Make only a small adjustment each time (about 1/16 – 1/8 of a turn) at a time until correct.
