Operation
Installing the Bit
Insert the bit (not provided) into the chuck jaws
with about 1” insertion. When using a small bit,
do not insert it so far that the jaws touch the
flutes of the bit. Make sure the bit is centered in
the chuck before tightening the chuck. The
chuck is a keyless model; simply rotate it by
hand to tighten the bit.
Positioning the Workpiece
Whenever possible, use
clamps or work hold-downs to secure the
workpiece to the table.
Always secure the workpiece to prevent it being
torn from the operator’s hand. Using the column
as a work stop is not recommended; instead,
use holding devices such as clamps. When
using the table in tilted position, make sure the
table is securely tightened and the workpiece is
clamped sufficiently.
For clean, splinter-free holes, place a piece of
scrap wood on the table below the workpiece.
Perform operations with a minimum extension of
the quill. Adjust table position rather than using
excessive quill travel.
Feed the bit into the material with only enough
force to allow the bit to work. Feeding too slowly
may cause burning of the workpiece. Feeding
too quickly may cause the motor to stop and/or
the bit to break.
General Inspection
Before each operation of your Model 2800 drill
press, make a habit of checking that all locking
handles, set screws, bolts, etc., are tight on the
table and head. Confirm that the drill bit is
securely inserted inside the chuck jaws.
Clear all items, such as tools and rags, away
from the machine.
Before attempting regular work, get the feel of
the drill press by practicing on scrap material.
For best results, always use sharp bits and
proper feed rates.
Setting Rotation Speed
There are several factors which determine the
best speed to use in any drill press operation,
such as kind of material being worked, size of
hole, type of drill, and quality of cut desired.
A general rule of thumb is, the smaller the drill,
the greater the required RPMs. And the speed
should be faster for soft materials and slower for
harder materials.
Maintenance
Before doing maintenance on
the machine, disconnect it from the electrical
supply by pulling out the plug or switching
off the main switch! Failure to comply may
cause serious injury.
After each use, clean sawdust from the table
with a brush (do not use your hands).
Occasionally apply a light film of oil to the quill
and column. This will reduce wear, prevent rust
and assure ease of operation.
Apply grease to the rack on the column.
Check that bolts are tight and electrical cords
are in good condition. Belts should be in good
condition and tensioned properly. Occasional
dressing of the belts with spray can type belt
dressing or paraffin wax will promote longer belt
life and quieter operation.
Bearings on the drill press are self-contained
and permanently lubricated; no further
lubrication is needed.
Exposed metal surfaces of the table and base
should be kept clean and free of rust. Apply a
good quality paste wax. Avoid any wax that
contains silicone or other synthetic ingredients.
These materials can find their way into lumber
and can make staining and finishing difficult.
The quill return spring should receive SAE 20 oil
once yearly. Apply the oil beneath the coil spring
cover (E, Figure 20) using a squirt can.
