slide clearance of the headstock and the tail 

stock must be checked and adjusted should it 

be needed prior to adjusting the centre point 

alignment.

Slide adjustment

Loosen the clamp handle on the tail stock and 

check for side movement. If it is excessive, 

insert an Allen key into the adjusting screw and 

tighten.

Note:

 By rotating the adjustment screw, it 

moves into the adjusting slot which opens and

removes the excessive clearance between the 

tail stock and the bed.

Note: 

Only make very small adjustments and 

then recheck the clearance. After adjustment

Centre points aligned the tail stock should be 

slid along the bed to check for any area that it 

binds in the bed slot. The same procedure as 

above should be conducted on the head stock 

should it be required.

Note:

 It is very unlikely that the headstock will 

require adjustment as it is not moved as often

as the tail stock, so has less tendency‘s for ware.

Center point alignment

The tail stock has two clamp screws that are 

accessible from the top of the tail stock.

The clamp screws hold the slide plate to the tail 

stock casting. There is clearance in the holes

that allows the tail stock to be moved in relation 

to the slide plate. The headstock also has two

clamp screws, but one is accessible from under 

the headstock.

By loosening the clamp screws the headstock 

and tail stock can be moved and the centre 

points aligned. 

Note: 

It is recommended that the head stock be 

adjusted and not the tail stock. If the tail stock is 

not adjusted parallel to the bed slide, the centre 

point will not be in alignment when the spindle 

is extended or retracted.

1. Loosen the clamp screw that is accessible 

from the top on the head stock.

2. Tap the side of the headstock with a rubber 

mallet close to the base in the direction 

requiring adjustment and retighten the clamp 

screw.

3. Recheck the centre point alignment and 

repeat if required.

Note:

 Never hit any part of the lathe that is cast 

iron with a metal hammer or similar as it 

will

break the casting.

8. Troubleshooting

Lathe will not start

1. Check that the start switch is in the correct 

position.

2. Check that the electrical power cord is 

plugged into the power outlet.

3. Check that the electrical supply is on (reset 

the breaker).

4. With the power disconnected from the  

machine, check that the wiring to the plug is 

correct. Check that the rubber insulation is 

stripped enough and is not causing a bad con-

nection. Check that all the screws are tight.

5. Emergency stop button engaged. Reset 

emergency stop button. Twist and it will pop out.

The machine will not stop

This is a very rare occurrence as the machine is 

designed to be fail-safe. If it should occur

and you cannot fix the fault, seek professional 

assistance. The machine must be disconnected 

from the power and never run until the fault has 

been rectified.

1. The stop switch is faulty. Replace the stop 

switch.

Motor tries to start but will not turn

1. With the power disconnected from the  

machine, try to turn the spindle by hand. If 

the spindle will not turn, check the reason for 

jamming.

2. Capacitor faulty. Replace the capacitor.

3. Motor faulty. Replace the motor.

4. Power line overloaded. Correct overloaded 

condition.

5. Low voltage. Correct low voltage condition.

Motor overheats

The motor is designed to run hot, but should it 

overheat it has an internal thermal overload

protector that will shut it down until the motor 

has cooled, and then it will reset automatically.

If the motor overheats, wait until it has cooled 

and restart. If the motor shuts down consistently

check for the reason. Typical reasons are dull 

cutting tools, the motor cooling fan being

clogged or faulty, the motor cooling fins are 

clogged, overfeeding the job, and excessive

ambient temperature.

Squeaking noise

1. Check that the motor cooling fan is not con-

tacting the fan cover.

2. Check the bearings.

3. Check the drive belt is tensioned correctly.

Spindle slows down during a cut

1. Dull cutting tools. Replace the tool or have it 

re-sharpened.

2. Feeding the wood too fast. Slow down the 

feed rate.

3. Oil or dirt on the drive belt. Clean or replace 

the drive belt.

4. Drive belt loose. Re-tension drive belt.

Machine vibrates

1. Machine not level on the floor. Re-level the 

machine ensuring that it has no movement.

2. Damaged drive belt. Replace the belt.

3. Job is not balanced. Change to slower speed 

and/ or balance the job.

4. Damaged pulley. Replace the pulley.

5. Worn spindle bearing. Replace the bearing.
