FITTING THE SAFETY GUARD DRILL GUARD INSTRUCTIONS Ensure drill unit is isolated from power supply. Fit guard to drill as shown. When drilling, the guard should always be in contact with the surface being drilled. As the drill is lowered, the guard will rise in relation to the drill. FITTING THE SAFETY CHAIN A safety chain should be used wherever possible as a safety precaution in the event of a power failure releasing the magnet; particularly in situations where the machine is clamped onto a vertical surface or in an inverted position. SAFETY CHAIN INSTRUCTIONS When the machine has been clamped to the workpiece in the correct position for drilling, the chain should be fitted at a secure part of the drill. Then passed around a substantial part of the workpiece and fastened securely. Once the cut is complete, the chain should be released, and the machine supported before the magnet is disengaged. FITTING THE OIL BOTTLE The cutting oil bottle is held in a sprung bracket attached to the top of the drill body. Fit the bracket by removing one of the cap screws from the top plate and replace the bolt through the fixing lug on the bottle bracket, tightening the bolt enough to allow some radial movement of the bracket. The coolant tube is a push fit into the self-seal gland at the base of the tap and a similar fitting on the lower arbor bracket.
