Wadkin OPERATING AND MAINTENANCE INSTRUCTIONSCHANGING OF DISC (See Fig. 1). Move the table horizontally away from the disc by rotating handwheel 'M'. The small knurled handwheel'N' holding the guard in position over the face of the disc should be unscrewed. This leaves the guardfree to be swung out of the way on the pivot 'P' securing it to the guard covering the back of the disc.Detach the two handles 'Q' from the body of the machine and screw into the holes tapped in the rim of thedisc. The guard over the rim of the disc is cut out in two opposite positions to allow the handles to beinserted into the rim of the disc whilst it is still fitted to the machine. Take out the four screws 'R' byunscrewing them from the back of the disc. Using the two handles lift the disc off the driving flangeplate and clear of the machine.Follow the reverse procedure when replacing the disc after a new abrasive has been attached.NOTE: Care must be taken to remove the handles from the rim of the disc before putting the machine touse.CHANGING OF ABRASIVE.To remove a worn abrasive from the sanding disc immerseit in a bath of hot water and leave for ten to fifteen minutes;when the paper will peel off. While the disc is in the bath,scrape and clean off all the old solution. Remove it fromthe bath and leave it to dry.When attaching a new abrasive the disc should be laid flaton a bench. Coat the surface with a thin layer of WadkinAdhesive Cement Grade C. 5. If it is extremely cold thecement should be warmed before use. Spread to an eventhickness with a roller or squeegee and leave until tacky.Afterwards put on the sheet of abrasive paper. The disccementing press as illustrated in Fig. 2 which is suppliedcompl ete with two sanding discs is now used. Place thenewly prepared disc in the press and by the aid of one ofthe other spare discs clamp and ieave for 12 hours or untilrequired whichever is the longer.www.wadkin.cominfo@wadkin.comcPress.

DUST COLLECTION.As already mentioned hoods are providedbelow the tables for collecting the dustwith outlets arranged to connept to anexhaust system. If a main dust extractingsystem is available the machine hoods maybe connected direct to the main suctionpiping.Alternatively a compact self-containeddust collector can be supplied as illustratedin Fig. 3. This unit very efficientlyhandles the fine dust and is recommendedwhere one machine only is installed. Itembodies a dust storage bin of four cubicfeet capacity made quickly detachable foremptying purposes. The dust laden air isfiltered through a series of flame-proofedfabric sleeves, while a motorised. shakingmechanism for periodic shaking preventsaccummulation of excessive dust. Fulldetails for operating and maintenance of theunit are given on an Instruction Sheet insidethe top lid of the unit.FIG. 3If the work consists of radio and televisioncabinets it is advisable to inform us in orderthat the correct type of dust collector is offered.Where a number of sanding machines are installed a separate system of dust collection quite distinct fromthe main suction plant is recommended. Advice on this will be given on request.www.wadkin.comABRASIVES.Garnet Paper Discs of varyirig grits and grades can be supplied to suit the class of work and the desiredfinish on woodwork. Discs of either 30" or 36" diameter with a 2t" diameter centre hole are available.Where it is desired to use the machine for metal working, suitable discs can be supplied in the followinggrades:- Aluminous oxide, Standard emery cloth, Silicon carbide and Corundum.info@wadkin.comPage 7
