b. Drill two mounting holes (Figure.8), and secure the base to the table with the two supplied carriage bolts and wing nuts. 2.. Place the column on the base, and install the four column bolts supplied. Figure.6..Secure base to floor. TIPPING.HAZARD!

Mounting Holes Figure.8..Workbenchmountingholes. ASSEMBLY -9 ASSEMBLY Table.Support The W1669 comes with a one geared table bracket. The W1670 comes with a geared table bracket and table support arm, which allows the distance between the column and table to be adjusted. No table support parts are interchangeable between the two drill presses. To.install.the.table.support.assembly,.do. these.steps: 1.. Insert the table lock lever through the unthreaded hole (see Figure.9) in the table bracket, and then tighten the lever into the threaded side exactly three turns. 2.. Starting with the pinion gear, insert the shaft into the table bracket and mesh the teeth with the worm gear as shown in Figure.9.. 3.. Align the set screw in the crank handle with the flat pad on pinion shaft. 4.. Tighten the 3mm set screw to lock the handle in place (see Figure.10). 5.. Examine the rack and note that the rack teeth at one end are cut closer to the end of the rack than the other. 6. Insert the rack through the table bracket so the end that has the rack teeth cut closer to the end is pointing down (see Figure. 11). 7. Hold the rack against the worm gear and slide the table bracket and rack onto the column (see Figure.11). Figure.9..Pinion and worm gear installation.

Seat the rack tapered-point into the bevel that is cut into the column support tube (see Figure.12). 9. Slide the column ring onto the column with the inside bevel in the down position until the rack tapered-point seats into the bevel (see Figure.13). 10. Position the column ring so the table bracket and rack can just rotate around the column without binding. 11. Carefully, snug the set screw to hold the column ring in place. Over-tightening the column ring will distort or split the column ring. Figure.12..Bevel and rack seated correctly. Tapered Rack Point and Column Support Tube Bevel.

DO.NOT over tighten the set screw, or you will bend the column or strip the threads. GET.help.to.lift.the.head- stock,.or.you.may.seri- ously.hurt.your.back.or. drop.the.headstock.. LockingGib Figure.14..Lockinggibinstallation. To.install.the.headstock.assembly,.do.these. steps: 1.. Place the locking gib into the recessed pocket on the inside of the column bracket casting (see Figure.14). 2. With an assistant, lift and position the headstock pocket over the column and allow the headstock to slide down until the column fully seats into the headstock (approximately 2", see Figure.15). 3.. Rotate the headstock directly over the foot of the base as viewed from the front of the drill press. 4. Screw in the two lock handles on the sides of the headstock. 5. Using a plumb bob and ruler, center the headstock with the base, and tighten the two set screws to secure the headstock to the column (see Figure.16). Figure.15. Headstock-to-column installation.

When properly joined, the JT-33 tapers on the spindle and inside the chuck create an almost permanent connection. To.install.the.drill.chuck,.do.these.steps: 1... Clean the drill chuck and spindle with mineral spirits and follow all safety warnings on the container (see Figure.17). Note: Failure to clean the tapered mating surfaces of the spindle and drill chuck may result in a loose or wobbly chuck. 2. Use the provided chuck key to adjust the jaws of the chuck until they are inside of the drill chuck body (see Figure.18). 3. Place the drill chuck on the spindle and tap the chuck onto the spindle with a block of wood or a dead-blow hammer (see Figure. 18). DO.NOT.use a metal hammer to seat the drill chuck onto the spindle! Figure.17..Clean the chuck before installation.
