10) the cup located on the base centers the pendulum . . .if the pendulumtouches the side or bottom of the cup, the clock will not operate accurately:This indicates that the clock does not stand on a level surface. In such acase accurate leveling is accomplished by adjusting the leveling screws (K)protruding from base of clock, enabling pendulum to rotate freely and theclock to operate satisfactorily. The cup also prevents the pendulum from swingingtoo much when the clock is moved . . . thereby preventing damage to the glassdome or suspension wire.
11) On the top of the pendulum is a disc (figure III), on which numbers areengraved 1 – 16 and two arrows marked F-S. the small indicator hand(L) will be pointing to a number on the disc at which the clock was regulatedbefore leaving the factory. Should you find it necessary to regulate the clockobserve the number to which the indicator hand points. The distance betweeneach number is equivalent to 1/2 minute in 24 hours + or -.
For example: If your clock loses two minutes per day (24 hours) and the indicatorhand points to number 8 on the disc – move the disc on the directionof the arrow marked F until the indicator hand will point to the number 4.

Observe the lever and escape wheel through the two holes in the back plate.When the lever (pallet) leaves a tooth of the escape wheel, the pendulum mustrotate a litter further. The pendulum will then rotate to the opposite sideand will also rotate a little further after the lever leaves a tooth of theescape wheel. If the distance the pendulum travels is unequal at both endsof the rotation, the clock is 'out of beat'. To put the clock 'inbeat' the method is as follows: On the back plate is a bridge (D) underwhich a small round pillar is attached and held by screw (F). The suspensionwire is held in place by a small bracket centered within this pillar. Screwedto the suspension wire at a slightly lower point is fork (E), which guidesthe lever. Loosen screw (F), turn the small pillar slightly, with the helpof the protruding arm (G) in the direction that more rotation is wanted, tomake it equal. Tighten screw (F).
