5.2 Securing base

It is strongly recommended that the drill press be secured to floor. The base has four mounting slots; see Figure 4-1. When securing base to floor, apply even torque to the fasteners to prevent distortion of base.

5.3 Assembly

Install crank handle onto worm gear shaft to raise and lower table. See B, Figure 7-1. Secure handle by tightening set screw.

Install smaller handle onto crank handle and tighten nut.

5.4 Cleanup

Exposed metal surfaces have been given a protective coating. Remove this with a soft cloth and a cleaner-degreaser or kerosene. Do not use gasoline, paint thinner or acetone, as these can mar painted surfaces. Do not use an abrasive pad, which may scratch polished surfaces.

Coat all exposed metal surfaces with a light coat of standard SAE20 machine tool oil, to inhibit rust.

Figure 5-1

Inspect contents of crate for shipping damage. Report any damage immediately to your distributor and shipping agent. Do not discard any shipping material until drill press is assembled and running properly.

Remove any fasteners holding drill press to pallet. Lift drill press with forklift or hoist with straps. (Note: Lifting point is beneath head and next to column.) Make sure handles, levers, etc. are clear of forks or straps when lifting. Lifting equipment must be properly rated for weight of drill press.

Position machine on a solid, level floor, preferably concrete. Area should have good overhead lighting and ventilation. (Refer to OSHA regulations for specific information about using drill presses in industrial environments.) The drill press should be level and rest solidly on floor. Place shims below base as needed to achieve level.

6.0 Electrical Connections

Electrical connections must

be made by a qualified electrician in compliance with all relevant codes. This machine must be properly grounded to help prevent electrical shock and possible fatal injury.

IMPORTANT: The JDPE-20EVS-PDF series Drill Presses operate on single phase, 115 volt incoming power.

The drill press uses an inverter (inside control box) to provide infinitely variable spindle speeds within the specified ranges. The inverter controls the speed of the motor by varying the frequency of the voltage supplied to the motor. It converts the 115V single phase input to run the three phase, 230V motor. The inverter has been programmed by the manufacturer; do not attempt to adjust or modify it. If you suspect a problem with the inverter, contact JET technical service.

Before connecting to power source, be sure switch is in off position.

It is recommended that the Drill Press be connected to a dedicated 20 amp circuit with circuit breaker or time delay fuse rated “D”. NOTE: Local codes take precedence over recommendations.

6.1 GROUNDING INSTRUCTIONS

This machine must be grounded. In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This tool is equipped with an electric cord having an equipment-grounding conductor. If a plug is installed, it must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances.

Improper connection of the equipment-grounding conductor can result in a risk of electric shock. The conductor with insulation having an outer surface that is green with or without yellow stripes is the equipment-grounding conductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equipmentgrounding conductor to a live terminal.

Check with a qualified

electrician or service personnel if the grounding instructions are not completely understood, or if in doubt as to whether the tool is properly grounded. Failure to comply may cause serious or fatal injury.

Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles that accept the tool's plug.

Repair or replace damaged or worn cord immediately.

Grounded, cord-connected tools intended for use on a supply circuit having a nominal rating less than 150 volts:

This tool may be used on a circuit that has an outlet that looks like the one illustrated in A, Figure 6-1. The tool is to be used with a grounding plug that looks like the plug illustrated in A. Make sure the tool is connected to an outlet having the same configuration as the plug. An adapter, shown in B, may be used to connect the plug to a 2-pole receptacle as shown in B if a properly grounded outlet is not available. The temporary adapter should be used only until a properly grounded outlet can be installed by a qualified electrician. The green-colored rigid ear, lug, and the like, extending from the adapter must be connected to a permanent ground such as a properly grounded outlet box. Note: In Canada, the use of a

temporary adaptor is not permitted by the Canadian Electrical Code, C22.1.

Figure 6-1

6.2 Extension cords

The use of extension cords is discouraged; try to position equipment within reach of the power source. If an extension cord becomes necessary, be sure it is heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating.

Table 2 shows recommended size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

8.7 Drilling recommendations

The following are only general recommendations. Consult a machinery handbook or contact the

specific tool manufacturer for more detailed information.

8.7.1 Drilling speeds

The speed of a drill is usually measured in terms of the rate at which the outer periphery of the tool moves in relation to the work being drilled. The common term for this is Surface Feet per Minute (SFM). The relationship of SFM is expressed in the following formulas:

SFM = 0.26 X rpm X Drill Diameter (in inches)

RPM = 3.8 x ________SFM__________ Drill diameter (in inches)

In general, the higher the speed the shorter the drill life. Operating at the low end of the speed range for a particular material will result in longer life. The most efficient speed for drill operation depends upon many variables:

1. Composition and hardness of material.

2. Depth of hole.

3. Efficiency of cutting fluid.

4. Type and condition of drilling machine.

5. Desired quality of hole.

6. Difficulty of set-up.

8.7.2 Drilling feed

The feed of a drill is governed by size of tool and the material drilled. Because feed rate partially determines rate of production and also is a factor in tool life, it should be chosen carefully for each job. In general, the most effective feeds will be found in the following ranges:

Diameter of Drill

(inches)

Under 1/8 0.001 to 0.002

1/8 to 1/4 0.002 to 0.004 1/4 to 1/2 0.004 to 0.007 1/2 to 5/8 0.007 to 0.015

Feed per Revolution

(inches)

Table 2

8.7.3 Excessive speed/feed indicators

A drill that splits up the web is evidence of too much feed or insufficient tip clearance at the center as a result of improper grinding. The rapid wearing away of the extreme outer corners of cutting edges indicates that speed is too high. A drill chipping or breaking out at the cutting edges indicates that either feed is too heavy or drill has been ground with too much tip clearance.

9.0 User-maintenance

9.1 General maintenance

1. After each use, wipe down the machine with a clean rag and apply a light coat of oil to exposed metal surfaces to inhibit rust.

2. Confirm that machine is properly lubricated. See sect. 9.3.

3. Keep table and T-slots clean and free of debris. Use a brush to clear shavings, not bare hands.

4. Periodically use compressed air or vacuum to clear any dust off motor fan. Use a vacuum to clear dust from cooling fan grill on control box.

5. Periodically check power cords to inverter, motor, lamp, etc. If any damage is found replace the cord immediately.

6. If drill press will not be used for an extended period, release latch (M, Figure 8-1) to reduce stress on belts.

9.2 Additional servicing

Any additional servicing should be performed by authorized service personnel.

9.3 Lubrication points

Regularly scheduled maintenance is crucial to ensure a long service life for your machine. The following are recommendations and may vary based upon frequency of use. Note: Ball bearings are pre-lubricated and sealed, and require no further attention. Disconnect machine from power before lubricating.
