1. to this part don t lay the clock down on its back Should you need to put the clock down place it upside down on its top plate where it will sit precariously balanced It will also survive being placed on the pillow we used earlier Watch that crutch though Fitting the Clock Mounting the clock on the wall bracket is straightforward Rotate the brass mounting bar found in the wall bracket so it points slightly up wards and hold the clock so that the rear mounting hole lines up with the mounting bar Locate the bar in the hole and gently slide the clock home Take care to ensure that the bracket arms pass below the top plate and above the escapement anchor Gently rotate the clock into place The crutch needs to locate correctly with its slot in the pendulum rod the end of the crutch is tapered to allow this to happen easily it is wise however to watch closely and take this part slowly When the clock is hanging vertically with the crutch en gaged give the top of the frame one final push toward the wall to make sure it is fully in place Fitting the weight cord First hold the two wooden terminals and let the cord hang make sure there are no knots and identify the shorter of the terminals Slide the shorter terminal into the hole on the left hand side of the pulley yoke Let the cord hang in a loop as you hold the other terminal Second from the right side pass this termin2. It needs to run in beat Both adjustments are made using the two allen keys provided which fit into the grub screws in the holes furthest forward in the clocks top plate Hanging the Clock Vertically This adjustment allows the clock to be in stalled on a wall that is not quite vertical You can tell at a glance if you need to per form this stage The pendulum is already hanging vertically from the bracket if the rear frame member is hanging parallel to the pendulum you may skip the rest of this page If both allen keys are rotated in the same direction at the same time the mechanism will slowly rock towards or away from the wall Adjust the allen keys together until the mechanism hangs vertically as viewed from the side pe 00900 ih ny Adjusting the Beat Leave the allen keys in place to make the second adjustment If these are now rotated in opposite directions as shown below the clock mechanism is made to rock from one side to the other First make a quick visual check to see that the front frame member is more or less vertical using the allen keys to correct as needed turning both keys by the same amount but in opposite directions Start the clock by gently swinging the pendulum Watch the escapement carefully in particular observe the how far the anchor pallets swing out away from the teeth this maximum should be the same on both sides The illustration shows which direction to turn
3. clock is allowed to run down it will stop the counterweight held neatly by the bottom of the frame Wind the clock again and gently restart The normal running of the clock can be disrupted by a few circumstances Should it become reluctant to work try these procedures Restart the clock if it runs check that it is running in beat the escapement anchor swings away from the es cape wheel by the same amount on each side This ad justment can drift over time re adjust with the allen keys if needed If the clock won t start the escape wheel doesn t rotate when the pendulum is swung several steps can be taken first take the escape wheel and gently jiggle it in and out and repeat for the intermediate wheel Now rotate the clock hands a full 12 hours before setting the time and re starting the clock Normally these methods will enable the clock to return to its normal stable running If it continues to require frequent re starts however it may need to be returned to the workshop Please do not hesitate to get in touch if you experience any difficulty with the clock Dismantling the and Re packing the Clock At some time it will be necessary to dismantle the clock for storage moving house or returning to the workshop for maintenance You will need the crate the old towel pillow and crosshead screwdriver used when the clock was first unpacked plus a new plastic cable tie and a pair of pliers e Wind the
