6 MACHINE OPERATION

WARNING● Always Wear Safety Glasses.● Always Wear Hearing Protection.● Wear respiratory protective equipment.● Never touch the mounted cutter and the rotating

parts of the machine such as the Spindle Arbor after the power cable is connected to power source.

6-1. Start and Stop● The Drill Motor will not rotate unless a Magnet

is turned on in operating the Motor Switch.

CAUTION● When the Trigger Switch of the Electric Drill

is not turned on, the Electric Drill will not start even the Main Dial Switch on the side of the body is turned to the “Drill ON” position. Leave the Trigger Switch on during the entire drilling work.

● When turn on both the Magnet and Electric Drill, pause momentarily at the “Magnet ON” position before switching over to the next “Electric Drill ON” position. Unless the Main Dial Switch is

steadily set to its ON stage once, the Electric Drill may not start.

WARNING● Always keep surfaces clean.

Always keep the Magnet surface clean.Alwayskeeptheworkpiecesurfaceclean.IfthereareanyforeignobjectsbetweentheMagnetandtheworkpiece surfaces, thiswill reducemagnetic power.This could cause the machine tomove duringoperation.This can result in anaccident.

(6) Set the Stabilizer properly

WARNINGThe Stabilizer serves as the effective counterbalance to the adhesive force of the Magnet. After switching on the Magnet, adjust it so that the Magnet clings to the work piece evenly without a gap. Make sure the Stabilizer Wheels are not protruding and lifting the Magnet off the plate.

6-4. Drilling Stacked Plates

CAUTION● Remove slug as each plated is finished:

otherwise, being blocked by the slug left unremoved, the cutter cannot cut into the next layer of plate, which results in the Magnet base being pushed up possibly causing accident.

● For stacked plates drilling, always feed and drill slowly and carefully.

● Before drilling stacked plates, securely clamp the plates together in place.

● When drilling stacked plates, retract the cutter as each layer of plate is finished in order to remove slug from the drilling area, then put another hole in the next layer of plate.

8 MAINTENANCE/SERVICE

WARNING●Always disconnect the power and turn off the

switch before attempting any maintenance. Failure to disconnect the power and turn off the switch during set up, inspection or maintenance can cause accidents and severe injuries.

8-1. Tighten Set Screw When Machine is Not UsedFor thepurposeof safety,when youdon’t use themachinetemporallyoronalong-termbasis,raisetheDrillMotor and set it inpositionwith theSetScrewso that itwill not comedownon its ownweight. IfyouleavethemachinealonewiththeDrillMotorinaloweredposition, thePilotPinand/or cuttermaybedamagedwhenthemachineisrelocated.BeforetighteningtheSetScrew,makesurethattheslide section in the Gearbox is properly aligned totheheadoftheSetScrew.

8-2. Grease the Sliding Surfaces from Time to TimeGreasethemachinebodyandSlideBoardfromtimetotime.

8-3. Gearbox Clearance AdjustmentExcessive clearance between the machine bodyand Gearbox would deteriorate not only drillingperformancebutalsocuttingtoollifetoasubstantialdegree. If you find excessive clearance, makeadjustment by tightening 5Slide BoardAdjustingScrewsonthesideof themachineusingthesametorque all round so that Drill Motor will not comedownonitsownweight.
