• Display panel (A) shows the spindle RPM.
• Button (B) turns power on and off to LED light.
MAINTENANCE
WARNING: Turn switch off and remove plug from power source
outlet before maintaining or lubricating your drill press
DRIVE BELT
Replace drive belt when worn.
LUBRICATION
Refer to Figures 7 and 8.
The ball bearings are lubricated at the factory and need no further
lubrication. Using 20wt. non-detergent oil, periodically lubricate the
splines (grooves) in the spindle and the rack (teeth on the quill) as
follows:
• Lower quill assembly (Figure 8, Ref. No. 143) all the way down.
• Apply lubricant around the inside of the hole in the spindle
pulley (Figure 8, Ref. Nos. 158 & 172).
• Apply lubricant to rack (teeth) on quill (Figure 8, Ref. No. 143)
while extended below drill press head.
• Apply lubricant to rack and pinion gear (Figure 7, Ref. Nos.
12/13) on column and table assembly.
CLEAN MOTOR
Frequently blow out any dust that may accumulate inside motor. If
power cord is worn, cut or damaged in any way, have it replaced
immediately.
IMPORTANT: To assure product SAFETY and RELIABILITY, repairs,
maintenance and adjustment (other than those listed in this
manual) should be performed by authorized service centers or
other qualified service organizations, always sing identical
replacement parts.
WARNING:
To avoid shock or fire hazard, if the power lead is worn
or cut in any way, replace it immediately.
