INSTALLING/CHANGING WORKLIGHT BULB
See Figure 12.
The integrated worklight can be used to help illuminate 
the work area. The worklight requires a 15-watt, 10-volt, 
 candelabra-base bulb (not included). 
To install, insert the bulb into the worklight receptacle and 
twist clockwise to secure.
MOUNTING THE DRILL PRESS
See Figure 13.
If the drill press is to be used in a permanent location, secure 
it to a workbench or other stable surface.
If the drill press is to be used as a portable tool, fasten it 
permanently to a mounting board that can easily be clamped 
to a workbench or other stable surface. The mounting board 
should be of sufficient size to avoid tipping while drill press 
is in use. Any good grade plywood or chipboard with a 
3/4 in. thickness is recommended.
	Mark holes on surface where drill press is to be mounted 
using holes in drill press base as a template for hole pat-
tern.
	Drill holes through mounting surface.
	Place drill press on mounting surface, aligning holes in 
the base with holes drilled in the mounting surface.
 Insert bolts (not included) and tighten securely with lock
washers and hex nuts (not included).
If lag bolts are used, make sure they are long enough to
go through holes in drill press base and material the drill 
press is being mounted to. If machine bolts are used, 
make sure bolts are long enough to go through holes in 
drill press, the material being mounted to, and the lock 
washers and hex nuts.
NOTE: All bolts should be inserted from the top. Install
the lock washers and hex nuts from the underside of the 
workbench.	
Once the drill press is securely mounted on a sturdy 
surface perform the following:
	
Check for vibration when the motor is switched
ON.
Adjust and retighten the mounting hardware as 
 necessary.
Check the table assembly to assure smooth movement 
up and down the column.
Check to assure that the spindle shaft moves smoothly.
