10.3General Inspection
Before each operation of your Model 2800B drill press, make a habit of checking that all locking handles, set screws, bolts, etc., are tight on the table and head. Confirm that drill bit is securely inserted inside chuck jaws.
Clear all items, such as tools and rags, away from 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.
10.4Setting 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.
11.0Maintenance
Before doing maintenance on the machine, disconnect it from 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).
Periodically apply a light film of oil to the quill and column. This will reduce wear, prevent rust and assure ease of operation.
It is good maintenance practice to periodically clean the pulleys with a
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 with no signs of cracks, frays or deterioration.
Bearings on the drill press are
Exposed metal surfaces of table and base should be kept clean and free of rust. Protective sprays or paste wax are available from most hardware stores. Note: Avoid wax that contains silicone or other synthetic ingredients; these materials can find their way into lumber and make staining and finishing difficult.
The quill return spring should receive SAE 20 oil once yearly. Apply the oil beneath the coil spring cover (L, Figure 20) using a squirt can.
11.1Belt replacement
Referring to Figures 26 and 27:
If future replacement of belts is needed, proceed as follows:
This procedure requires operating machine with pulley cover removed. Keep hands away from moving belts and pulleys.
1.Remove pulley cover using a long shaft screwdriver.
2.Turn on drill press and increase speed (rotate handwheel clockwise) to maximum, to bring center pulley as far toward spindle pulley as possible.
3.Shut off drill press and disconnect from power.
4.Firmly squeeze center section of upper belt to slacken tension. See Figure 26. If needed, pull on belt away from center pulley to further slacken.
Figure 26
5.Remove upper belt from around pulleys.
6.Reconnect to power, turn on drill press and rotate handwheel counterclockwise until center pulley is as close to motor pulley as possible. See Figure 27.
