Fig 4Install three down feed handles (A, Fig5) into the down feed hub (B).Fig 5Chuck guard Assembly:Remove knurled bolt (D, Fig 6)Remove screw (A Fig 6),Insert the chuck guard (B Fig 6),Install screw (A Fig 6),Fig 6Install knurled bolt (D Fig 6).Safety Note:For machine operation, the chuckguard must always be closed andlocked with screw (D).Raise the table to approximately200mm below the spindle assembly.Lock the table.Place a piece of scrap wood on thetable.Thoroughly clean the spindle opening,the arbor, and the chuck.Important:These three pieces must be free ofany rust protection or lubricant. If theyare not clean, the arbor and chuck willfail to seat in the spindle and will fallout.Place the arbor into the chuck.Twist the chuck to retract the chuckjaws if they are exposed.Place the arbor and chuck assemblyinto the spindle.Turn the arbor and chuck assemblyuntil the tang on the arbor engages theslot at the end of the spindle.Lower the down feed handle so thatthe chuck meets the scrap wood.Pressure on the down feed handleonce the chuck meets the scrap woodseats the arbor and chuck into thespindle (see Fig 7).Fig 75.3 Mains connectionMains connection and any extensioncords used must comply withapplicable regulations.The mains voltage must comply withthe information on the machine licenceplate.The mains connection must have a10 A surge-proof fuse.Only use power cords marked H07RN-FConnections and repairs to theelectrical equipment may only becarried out by qualified electricians.5.4 Starting operationYou can start the machine with thegreen on button. The red button on themain switch stops the machine.6. Machine operationAlways adjust the table and the depthstop to prevent drilling into the table.Use a back-up piece of scrap wood tocover the table. This protects both thetable and the drill bit.Secure workpiece to the table withclamps or a vice to prevent rotatingwith the drill bit.Feed the bit into the material with onlyenough force to allow the drill bit towork. Feeding too slowly may causeburning of the workpiece. Feeding tooquickly may cause the motor to stopand/or the drill bit to break.Recommended speeds for a 10mmHSS drill:Wood: 2000 RPMPlastic: 1500 RPMAluminium: 1500 RPMBrass: 1500 RPMCast iron: 1000 RPMMild steel: 800 RPMHigh carbon steel: 600 RPMStainless steel: 300 RPMGenerally speaking, the smaller inrelation the drill bit, the greater theRPM required.Wood requires higher speeds thanmetal.Metal is usually drilled at slowerspeeds; cutting oil is applied ifnecessary.Warning:Always keep your hands well clear ofthe rotating bit.Do not remove chips and workpieceparts until the machine is at astandstill.Always close the chuck guard andpulley cover before you start themachine.When using a drill press vice, alwaysfasten it to the table.Never do any works “freehand” (hand-holding the work piece rather thansupporting it on the table), exceptwhen polishing.
