GROUNDING INSTRUCTIONS
In the event of an electrical malfunction or short circuit, grounding reduces the risk of electric shock. This ma­chine is wired for 110V single phase operation and is equipped with a 3-conductor cord and a 3-prong grounding plug A to fit a grounded type receptacle B. Do not remove the 3rd prong (grounding pin) to make it fit into an old 2-hole wall socket or extension cord. If an adaptor plug is used, it must be attached to the metal screw of the receptacle C.
Note: The use of an adaptor plug is illegal in some areas. Check your local codes. If you have any doubts or if the supplied plug does not correspond to your electrical outlet, consult a qualified electrician before proceeding.
C
EXTENSION CORDS
If you find it necessary to use an extension cord with your machine, use only 3-wire extension cords that have 3- prong grounding plug and a matching 3-pole receptacle that accepts the tool’s plug. Repair or replace a damaged extension cord or plug immedi­ately.
Make sure the cord rating is suitable for the amperage listed on the motor I.D. plate. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. The accompanying chart shows the correct size extension cord to be used based on cord length and motor I.D. plate amp rating. If in doubt, use the next heavier gauge. The smaller the number, the heavier the gauge.

CIRCUIT CAPACITY
Make sure that the wires in your circuit are capable of handling the amperage draw from your machine, as well as any other machines that could be operating on the same circuit. If you are unsure, consult a qualified electrician. If the circuit breaker trips or the fuse blows regularly, your machine may be operating on a circuit that is close to its amperage draw capacity. However, if an unusual amperage draw does not exist and a power failure still occurs, contact a qualified technician or our service department.

CLEAN UP
BE SURE TO WORK IN A WELL VENTILATED AREA FOR THE CLEAN-UP PROCESS.
The unpainted cast-iron surface of the lathe bed is covered with a protective coating that helps prevent rust from forming during shipping and storage. Remove this protective coating by rubbing with a rag dipped in kerosene, mineral spirits or paint thinner. (Handle and dispose of potentially flammable solvent soaked rags according to manufacturers’ safety recommendations.) Avoid rubbing the lathes painted surfaces as many solvent based prod­ucts will remove paint.
To prevent rust, apply a light coating of paste wax or use regular applications of any after-market surface protec­tant or rust inhibitor.
PLACEMENT WITHIN THE SHOP / LIFTING AND HANDLING
THIS MODEL 25-300QC 14" X 30" WOOD LATHE IS VERY HEAVY. DO NOT OVER-EXERT. THE HELP OF AT LEAST TWO ASSISTANTS WILL BE NEEDED FOR THE FOLLOWING STEP.
TO LIMIT THE RISK OF SERIOUS INJURY OR DAMAGE TO THE MACHINE, ANY EQUIPMENT USED TO LIFT THIS MACHINE (HOIST OR FORKLIFT) SHOULD HAVE A RATED CAPACITY IN EXCESS OF 385 LBS (175 KG).
PLACEMENT WITHIN THE SHOP
This machine should be installed and operated only on a solid, flat and stable floor that is able to support the weight of the lathe and the operator.
Plan for placement within your shop that will allow the operator to work unencumbered and unobstructed by foot traffic (either passing shop visitors or other shop workers) or other tools or machinery.
LIFTING AND HANDLING THE MACHINE
Because of its great weight a minimum of two extra people will be required to assist with lifting the wood lathe and installing its support legs. That being said, to limit the risk of serious injury or damage to the machine, ideally, a hoist or lift should be used.
1. Remove the straps and wood blocks that hold the lathe to the pallet and remove the plastic bag.
2. Thread two leveling feet into the threaded holes of the legs A. Loosely tighten the hex nuts against the bottom of the legs B.
3. A) Lifting with a lift of hoist
Lift the lathe off the pallet using a forklift or hoist, and move the lathe to the desired location then install the wood lathe on its support legs as instructed in step 4 while the lathe is still held by the forklift or hoist.
Note: Pay special attention to the balance of the machine while lifting. (The motor side is much heavier).
B) Lifting with the help of assistants:

For turning applications where the workpiece cannot be secured between the headstock and tailstock cen­ters (such as bowl turning) the face plate must be used to secure the workpiece to the headstock spindle.
1. Unlock the face plate by loosening and removing the two set screws A using a 3 mm Allen key.
2. Loosen the face plate by inserting the supplied spindle lock pin B in one of the spindle holes to keep the spindle from turning, while loosening the face plate using the supplied face plate wrench, as shown in C.

3. Unscrew and remove the face plate, D.
4. With the face plate removed from the lathe
the workpiece onto the face plate with wood screws (not included) through the mounting holes from the back of the face plate.
Note: Make sure the screws are not so long that they will enter the area of the workpiece where the materi­al is to be removed.
5. Thread the face plate back on the lathe and tight­en using the spindle lock pin and face plate wrench.

NEVER TURN ON THE LATHE WHEN THE HEADSTOCK SPINDLE IS LOCKED IN PLACE. ALWAYS, TURN OFF AND UNPLUG THE LATHE FROM THE POWER SOURCE, BEFORE INSERTING THE INDEXING PIN TO LOCK THE SPINDLE.
TURNING ON THE LATHE AFTER THE SPINDLE LOCK PIN (OR ANY OTHER OBJECT) HAS BEEN INSERTED INTO THE HEADSTOCK INDEXING HOLE, THEREBY PREVENTING THE HEADSTOCK SPINDLE FROM TURNING, CAN LEAD TO SERIOUS INJURY, DAMAGE TO THE WORKPIECE, OR DAMAGE TO THE LATHE AND THE MOTOR.
PIVOTING THE HEADSTOCK (FOR OUTBOARD TURNING)
The headstock pivots 360° with positive stops at 45°, 90°, 135° and 180° for multi-position outboard turning. Larger bowls can also be turned on the outboard side of the lathe, with the help of an optional outboard turning brack­et #25-305. To pivot the headstock:
C
B
A
1. Release the heastock locking lever A.
2. Pull up on the headstock pivot pin to release the headstock B.
16
D
3. Rotate the headstock to the desired position C and release the pivot pin so it seats in the correspond­ing stop hole D.
4. Secure the headstock in place by pulling the headstock locking lever A forward.
Page 17
CHECKING ALIGNMENT BETWEEN CENTERS
A
There is a small amount of play built into the head­stock on the bed to allow the headstock to pivot freely. Whenever the headstock is pivoted back from the out­board position, the alignment between the headstock and tailstock centers should be double checked and adjusted as needed.
1. Pivot the headstock to its normal spindle turning position (0º) and lock it in place.
2.
Install a spur center in the headstock and a live center in the tailstock.
3.
Release the tailstock locking lever and advance the tailstock on the bed A until the points of the 2 centers just barely touch each other.
TOP VIEW
C
B
4. Using the tailstock locking lever, secure the tail stock on the bed with the points still touching.
5. Look down at the two centers from above B to ve­rify that the points are in alignment. If the points line up, proceed with normal turning operations.
6. If the points are not lined up release the head­stock locking lever and manually adjust the headstock position using the play in the head­stock to line up the center points C.
7. With the points lined up, hold the headstock in place and tighten the headstock locking lever.
8. With the points lined up, proceed with normal turning operations.
INDEXING
For advanced turners, the indexing features on this 25-300QC M1 lathe allows the user to lock the spindle in place at 36 evenly spaced 10° intervals while the workpiece is installed between the centers. This is primarily used for reed­ing or fluting (cutting decorative grooves vertically up the length of the spindle) usually with the help of a shop made jig and router.
NEVER TURN ON THE LATHE WHEN THE HEADSTOCK SPIN­DLE IS LOCKED IN PLACE. ALWAYS, TURN OFF AND UNPLUG THE LATHE FROM THE POWER SOURCE, BEFORE INSERTING THE INDEXING PIN TO LOCK THE SPINDLE.
TURNING ON THE LATHE AFTER THE INDEXING PIN (OR ANY OTHER OBJECT) HAS BEEN INSERTED INTO THE HEAD­STOCK INDEXING HOLE, THEREBY PREVENTING THE HEAD­STOCK SPINDLE FROM TURNING, CAN LEAD TO SERIOUS INJURY, DAMAGE TO THE WORKPIECE, OR DAMAGE TO THE LATHE AND THE MOTOR.
To lock the spindle:
1. Loosen the indexing pin A.
2. While slowly turning the flywheel B by hand, press
the indexing pin in until the pin finds and bottoms out in an indexing hole, then re-tighten the index­ing pin.
3. Complete the desired cut, groove or other opera­tion on the spindle.
4. If further grooves are required, loosen the pin again and slowly turn the spindle until the pin locks into the next, or the desired position.
Note: There are 36 evenly spaced holes in the headstock spindle allowing for indexing at 10° increments (360°/36 positions = 10°) C, allowing for a wide variety of symmet­rical decorative grooves or patterned cuts.

PERIODIC MAINTENANCE
Keep the unit clean and free of dust by wiping with a cloth or vacuuming off any woodchips or dust after
ach use.
e
ll bearings are sealed and permanently lubricated and no further lubrication is required.
A
Regular applications of a surface protectant/lubricant will help prevent rust and keep the tool rest, head, and tailstock sliding smooth on the bedway.
Periodically inspect the power cord and plug for damage. Replace the power cord and the plug at the first signs of visible damage.
RECOMMENDED OPTIONAL ACCESSORIES
A large range of optional aftermarket accessories can be used with this lathe. Your local dealer may be able to offer suggestions based on what is readily available in your area.
Key issues to keep in mind when shopping for aftermarket accessories are:
Headstock and tailstock feature a MT#2 taper – to avoid damaging the lathe use only headstock and tailstock centers with a matching taper.
Headstock spindle threads are 1” diameter x 8 threads per inch (T.P.I.) – to avoid stripping or damaging the threads, use only threaded headstock attachments (such as face plates and jaw chucks) that have matching threads.
We also offer a large variety of products to help you increase convenience, productivity, accuracy and safety when using your wood lathe Here’s a small sampling of optional accessories available from your local General International dealer.
For more information about our products, please visit our website at www.general.ca
