GENERAL SAFETY RULES
Failure to follow these rules may result in serious personal injury.
1.For your own safety, read the instruction manual before operating the machine. Learning the machine’s application, limitations, and specific hazards will greatly minimize the possibility of accidents and injury.
2.Wear eye and hearing protection and always use safety glasses. Everyday eyeglasses are not safety glasses. Use certified safety equipment. Eye protection equipment should comply with ANSI Z87.1 standards. Hearing equipment should comply with ANSI S3.19 standards.
3.Wear proper apparel. Do not wear loose clothing, gloves, neckties, rings, bracelets, or other jewelry which may get caught in moving parts. Nonslip protective footwear is recommended. Wear protective hair covering to contain long hair.
4.Do not use the machine in a dangerous environment.
The use of power tools in damp or wet locations or in rain can cause shock or electrocution. Keep your work area well-lit to prevent tripping or placing arms, hands, and fingers in danger.
5.Do not operate electric tools near flammable liquids or in gaseous or explosive atmospheres. Motors and switches in these tools may spark and ignite fumes.
6.Maintain all tools and machines in peak condition.
Keep tools sharp and clean for best and safest performance. Follow instructions for lubricating and changing accessories. Poorly maintained tools and machines can further damage the tool or machine and/or cause injury.
7.Check for damaged parts. Before using the machine, check for any damaged parts. Check for alignment of moving parts, binding of moving parts, breakage of parts, and any other conditions that may affect its operation. A guard or any other part that is damaged should be properly repaired or replaced with DELTA® or factory authorized replacement parts. Damaged parts can cause further damage to the machine and/or injury.
8.Keep the work area clean. Cluttered areas and benches invite accidents.
9.Keep children and visitors away. Your shop is a potentially dangerous environment. Children and visitors can be injured.
10.Reduce the risk of unintentional starting. Make sure that the switch is in the “OFF” position before plugging in the power cord. In the event of a power failure, move the switch to the “OFF” position. An accidental start-up can cause injury. Do not touch the plug’s metal prongs when unplugging or plugging in the cord.
11.Use the guards. Check to see that all safety devices are in place, secured, and working correctly to prevent injury.
12.Remove adjusting keys and wrenches before starting the machine. Tools, scrap pieces, and other debris can be thrown at high speed, causing injury.

POWER CONNECTIONS
A separate electrical circuit should be used for your machines. This circuit should not be less than #12 wire and should be protected with a time delay fuse. NOTE: Time delay fuses should be marked “D” in Canada and “T” in the US. If an extension cord is used, use only 3-wire extension cords which have 3-prong grounding type plugs and matching receptacle which will accept the machine’s plug. Before connecting the machine to the power line, make sure the switch (s) is in the “OFF” position and be sure that the electric current is of the same characteristics as indicated on the machine. All line connections should make good contact. Running on low voltage will damage the machine.
To reduce the risk of injury, do not expose the machine to rain or operate the machine in damp locations.
MOTOR SPECIFICATIONS
Your machine is wired for 120 volt, 60 HZ alternating current. Before connecting the machine to the power source, make sure the switch is in the “OFF” position.
GROUNDING INSTRUCTIONS
This machine must be grounded while in use to protect the operator from electric shock.
1.All grounded, cord-connected machines:
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 machine is equipped with an electric cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances.
Do not modify the plug provided - if it will not fit the outlet, have the proper outlet installed by a qualified electrician.
Improper connection of the equipment-grounding conductor can result in 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 equipment-grounding conductor to a live terminal.
Check with a qualified electrician or service personnel if the grounding instruction are not completely understood, or if in doubt as to whether the machine is properly grounded.
Use only 3-wire extension cords that have 3-prong grounding type plugs and matching 3-conductor receptacles that accept the machine’s plug, as shown in Fig. A.
Repair or replace damaged or worn cord immediately.
2.Grounded, cord-connected machines intended for use on a supply circuit having a nominal rating less than 150 volts:
If the machine is intended for use on a circuit that has an outlet that looks like the one illustrated in Fig. A, the machine will have a grounding plug that looks like the plug illustrated in Fig. A. A temporary adapter, which looks like the adapter illustrated in Fig. B may be used to connect this plug to a matching 2-conductor receptacle as shown in Fig. 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. Whenever the adapter is used, it must be held in place with a metal screw.
NOTE: In Canada, the use of a temporary adapter is not permitted by the Canadian Electric Code.
In all cases, make certain that the receptacle in question is properly grounded. If you are not sure, have a qualified electrician check the receptacle.

CHANGING LATHE SPEEDS
To reduce the risk of injury, do not operate lathe with pulley cover door open.
For the 46-455 lathe, the lathe speed is determined by one of five pulley sets (See Changing Pulleys section below.) The pulleys with the 46-455 lathe provide five different speed settings: 500, 950, 1550, 2700 and 4000 RPMs.
The 46-460 lathe is equipped with electronic variable speed control. Changing among the three pulley sets (see Changing Pulleys section below) determines the lathe's speed range and a control knob dials the speed up or down within that range. The pulleys with the 46-460 lathe provide three different speed ranges: 250-750 RPMs, 600-1800 RPMs and 1350-4000 RPMs.

NOTE: The belt tension is pre-set at the factory and should only require adjusting if the belt stretches over time or is replaced.
1.Open pulley cover (X) Fig. 14 and side door (AA) Fig. 16.
2.Pull down belt tensioning lever (Y) Fig. 15 to release belt tension. Do not lock it below the tab (Z).
3.Turn thumbwheel (DD) Fig. 19 clockwise to increase tension, or counterclockwise to decrease tension.
NOTE: A properly tensioned belt should deflect approximately 1/4" (6.4 mm) with moderate finger pressure.
4.Lift lever (Y) Fig. 15 and snap into place.
5.Close lower side door (AA) Fig. 16 and pulley cover
(X) Fig. 14 securely.
ELECTRONIC VARIABLE SPEED CONTROL (46-460 ONLY)
Once you select a speed range (as described above in Changing Pulleys section), use the speed control knob (EE) Fig. 20 to vary the speed within that range. As you face the lathe, turn knob forwards (towards you) to increase speed, turn it backwards (or away from you) to decrease speed.
To reduce the risk of injury, always set the speed control knob to its lowest setting before starting the lathe. Never start a workpiece at maximum speed.
INDEXING PIN
The lathe is equipped with an indexing pin (FF) Fig. 21. The pin allows the spindle (GG) to be locked in 24 positions—as labeled on indexing wheel (HH)—for use in various operations. To use:
1.Rotate idexing wheel (HH) so spindle (GG) is in desired location.
2.Pull back index pin (FF) slightly from retaining groove.
3.Rotate indexing pin 90 degrees so the crosspin (II) lines up with recess, as shown in Fig. 21a.
4.Release indexing pin (FF) so that it engages numbered indexing wheel (HH) Fig. 21 and locks spindle (GG) in place.
Do not turn on lathe with index pin engaged. Doing so could damage the lathe.
Do not use the index pin (FF) to lock spindle when removing faceplate because this can damage the pin. To remove faceplate, follow directions under Removing Faceplate section.

STARTING AND STOPPING LATHE
To reduce the risk of injury, make sure that the ON/OFF switch is in the "OFF" position before plugging cord into outlet. Do not touch the plug’s metal prongs when unplugging or plugging in the cord.
To turn lathe on, lift switch paddle (JJ) Fig. 22 up to the "ON" position. To turn lathe off, push switch paddle down
to the "OFF" position
LOCKING SWITCH IN THE "OFF" POSITION
To reduce the risk of injury, in the event of a power outage (such as a breaker or fuse trip), always move the switch to the “OFF” position until the main power is restored.
IMPORTANT: When the machine is not in use, the switch should be locked in the "OFF" position to prevent unauthorized use, using a padlock (KK) Fig. 23 with a 1/4" (6.4 mm) diameter shackle.
MOTOR OVERLOAD PROTECTOR
The tool is equipped with a manual reset circuit breaker. If the tool is overloaded or stalled too long the circuit breaker will trip causing the tool to shut off.
To restart:
1.Set the ON/OFF switch to "OFF"
2.Allow the motor to cool 3-5 minutes.
3.Press the reset button (LL) Fig. 24.
4.Resume normal operations.

MACHINE USE
To reduce the risk of injury:
•Tighten all screws and levers securely when adjusting any part of the lathe.Also, be sure any lathe accessories are fastened and tightened before turning on the lathe.
•When using the included 3" (76 mm) faceplate (B) Fig. 25, do not mount pieces larger than 6" (152 mm) in diameter and up to 6" (152 mm) in length. For mounting larger pieces, be sure to use an appropriately sized faceplate.
•Keep hands off workpiece when it is spinning.
•Use only accessories recommended for this product and follow all instructions included with the accessories.
•Be sure cord is not in the way of the spinning workpiece or spinning lathe parts.
•Do not touch the tip of your turning tool directly after it has been used on the workpiece as it may be hot.
•Do not apply water or other coolants to lathe when it is spinning.
•Do not turn materials other than wood on this lathe. This lathe was designed for wood turning only.
•Be sure any chuck keys or wrenches are out of the chuck before operating the lathe.
•FOR THE DELTA® MODEL 46-460 MIDI-LATHE ONLY: Be sure to only use accessories equipped with locking set screws for turning the lathe in reverse. Also, do not switch lathe turning directions until the workpiece comes to a complete stop.
MOUNTING THE WORKPIECE
NOTE: When mounting a workpiece, first tap the spur center into the workpiece using a soft mallet before installing into headstock.
A typical bowl mount is shown in Fig. 25. Workpieces can be mounted to the faceplate through the faceplate's four holes using screws appropriate for the type of wood being turned.
Another type of workpiece mount, where the workpiece is fixed between the spur and live centers, is shown in Fig. 26. Here are some tips on this mount:
1.Mount the workpiece by moving the tailstock to a position about 1" or 1-1/2" (25 mm or 38 mm) from the end of the workpiece and locking it in this position.
2.Advance the live center (E) by turning the tailstock crank
(P)Fig. 27 until the center cup makes contact with the workpiece.
3.Do not support the workpiece on the center pin alone. Always have the rim of the center cup imbedded at least 1/8" (3.2 mm) into the workpiece.
4.Lock the quill locking screw (O).

TURNING IN REVERSE (46-460 ONLY)
FOR THE DELTA® MODEL 46-460 MIDILATHE ONLY: To reduce the risk of injury, be sure to only use accessories equipped with locking set screws for turning the lathe in reverse. Also, do not switch lathe turning directions until the workpiece comes to a complete stop.
Care should be taken not to stall the workpiece when turning in reverse. If a stall should occur, stop the lathe and verify that the chuck or faceplate is fully seated and both set screws are tight before continuing.
MM 
The lathe comes ready to turn forward (downwards |
Fig. 28 |
|
toward the user) for typical woodturning applications. |
|
|
However, some applications require the lathe to turn in |
|
|
reverse (upwards away from user). The 46-460 can turn |
|
|
in reverse. To do this: |
|
|
1. |
Be sure the lathe power switch is turned off and that |
|
|
the spindle is not spinning. |
|
2. |
Slide switch (MM) Fig. 28 to “FWD” (forward) or |
|
|
“REV” (reverse) position, depending on your desired |
|
|
rotation. |
|
NOTE: The forward/reverse switch (marked FWD/ REV) employs a lockout feature to prevent switching directions when the ON/OFF switch is in the raised, or "ON" position.
3. If using a faceplate, chuck or other accessory that must be screwed on to the spindle nose, be sure the set screws are securely tightened before running in reverse.
