GENERAL SAFETY RULES
WARNING: Do not attempt to operate the machine until you have read thoroughly and understood
completely all instructions, rules, etc. contained in this manual. Failure to comply may result in accidents
involving fire, electric shock, or serious personal injury. Keep this owner's manual and review frequently for
continuous safe operation.
1. Know your machine. For your own safety, read the owner's manual carefully. Learn its application and
limitations, as well as specific potential hazards pertinent to this machine.
2. Make sure all tools are properly earthed.
3. Keep guards in place and in working order. If a guard must be removed for maintenance or cleaning,
make sure it is properly replaced before using the machine again.
4. Remove adjusting keys and spanners. Form a habit of checking to see that the keys and adjusting
spanners are removed from the machine before switched it on.
5. Keep your work area clean. Cluttered areas and workbenches increase the chance of an accident.
6. Do not use in dangerous environments. Do not use power tools in damp or wet locations, or expose
them to rain. Keep work areas well illuminated.
7. Keep children away. All visitors should be kept a safe distance from the work area.
8. Make workshop childproof. Use padlocks, master switches and remove starter keys.
9. Do not force the machine. It will do the job better and be safer at the rate for which it is designed.
10. Use the right tools. Do not force the machine or attachments to do a job for which they are not
designed. Contact the manufacturer or distributor if there is any question about the machine's suitability for
a particular job.
11. Wear proper apparel. Avoid loose clothing, gloves, ties, rings, bracelets, and jewellery which could get
caught in moving parts. Non-slip footwear is recommended. Wear protective hair covering to contain long
hair.
12. Always use safety glasses. Normal spectacles only have impact resistant lenses. They are not safety
glasses.
13. Do not over-reach. Keep proper footing and balance at all times.
14. Maintain machine in good condition. Keep machine clean for best and safest performance. Follow
instructions for lubrication and changing accessories.
15. Disconnect the machine from power source before servicing and when changing the drive belt.
16. To avoid accidental starting, make sure the switch is in the OFF position before plugging in the mains
cable.
17. Never leave the machine running unattended. Turn the power off. Do not leave the machine until it
comes to a complete stop.
18. Do not use any power tools while under the effects of drugs, alcohol or medication.
19. Always wear a face or dust mask if operation creates a lot of dust and/or chips. Always operate the tool
in a well ventilated area and provide for proper dust removal. Use a suitable dust extractor.

ADDITIONAL RULES FOR LATHES
Never attempt to adjust any part of the workpiece whilst the lathe is still in motion. Wait until the workpiece
has come to a complete stop.
1. Ensure that chuck keys, tommy bars and similar items are removed before the lathe is started.
2. Always stand to one side when you start the lathe so that if anything does fly off e.g. a loose piece of
bark, you will be out of the line-of-fire.
3. When mounting a new piece of timber, rotate the wood through 360o by hand to ensure that it will not hit
the tool rest or the bed of the lathe and then start the lathe at its slowest speed. When you are certain that
that the work is secure and not too out of balance set the lathe to the normal turning speed.
4. Always check the rotation speed before switching the lathe on to avoid the risk of starting it whilst it is set
to run at too high a speed.
5. The speed of the lathe must be adjusted to suit the size, balance, length and condition of the timber
being turned. The greater the diameter of the work, the slower the rotation speed needs to be. If the piece
you are turning is out of balance, then you must start turning at a low speed, until it is balanced.
6. The tool must rest firmly on the tool rest before it is brought into contact with the rotating wood and must
never be lifted off the tool rest as long as it is in contact with the timber.
7. Before sanding, polishing or doing anything else that brings your fingers close to the work, remove the
tool rest. Getting your fingers trapped between the tool rest and the work will at least be very painful and
may cause serious injury.
8. Never wrap the sandpaper of polishing cloth round the work. If it tightens up it will pull your fingers into
contact with the timber and may lead to serious injury.

Unpacking
Bolts securing legs to side of crate
All parts are contained in one crate.
Cut the retaining straps and prise off the lid
of the crate. Care must be taken as it is
secured with sharp pins.
Using a 13mm spanner, remove the two bolts
securing the legs to the side of the crate.
Prise off the front of the crate and lift out the
lathe legs. The lathe and legs are extremely
heavy and assistance will be required.
Page 6
The legs are connected together by brackets
at each end which should be removed and
discarded (13mm & 16mm spanners).
Unpack the parts from the accessories box
and check that everything is present as
shown.
If anything is missing contact your retailer
immediately.
With the accessory box and legs removed,
the remaining sides of the crate should now
be prised apart to leave only the lathe
attached to its pallet.
Page 7
Remove Release Levers Remove
The attachment of the legs will be made
easier if the headstock, toolrest and tailstock
assemblies are temporarily removed from
the bed in order to reduce weight.
Using a large flat blade screwdriver, remove
the two bed end stops – one located at each
end of the lathe.
Release the levers locking the headstock
(requires handle from accessory box), banjo
and tailstock – then remove each item by
sliding off the end of the bed.
Remove the four nuts and washers from the
bolts attaching the bed to the pallet and lift
clear, laying it on its top face ready to accept
the legs.
Using the 8mm hex key, attach the two legs
with the eight M10 x 35mm cap head bolts &
spring washers supplied.
The leg with the two holes for mounting the
Tool Rack is fitted to the headstock end of
the bed.
The leg with the four extension bed mounting
holes is fitted to the end of the bed with
similar holes.
Page 8
Attach one foot to each of the legs.
These can be adjusted to level the lathe bed
when it is in its final position.
Invert the bed/leg assembly.
Attach the Tool Rack to the left hand leg with
two M8 x 16mm bolts, flat & spring washers.
Refit the headstock, toolrest and tailstock
assemblies to the lathe bed.
The headstock is fitted at the tool rack end of
the bed.
Replace the two end stops.
Adjusting the Spindle Speed
The lathe has electronic speed control.
There are two ranges of speeds which
are obtained by changing the position of
the drive belt.
To adjust the drive belt position:
1) Open the belt/pulley access door by
unscrewing the securing screw with the
3mm hex key. (this screw can be
replaced by the knurled head screw
supplied but only if the lathe is being used
in a non-European Union country)
Page 9
Locking Handle Belt Tensioning Lever
2) Loosen the belt by releasing the
locking handle and lifting the tensioning
lever. Retighten the locking handle with
the lever in this raised position.
3) Position the belt on the left or right sets
of pulleys according to which speed range
you require.
The High Speed range (left hand pulleys)
will provide maximum speed whereas the
Low Speed range (right hand pulleys) will
provide maximum torque.
Always remove the belt from the larger
pulley first.
Re-tension the belt by releasing the
locking handle and lowering the
tensioning lever. The weight of the motor
will provide the correct amount of tension.
Tighten the locking handle in this position.
Close the belt cover and re-tighten the
securing screw.

Forward/Reverse Control
The Forward/Reverse switch should
never be used when the lathe spindle is
still rotating.
Always stop the lathe by using the
ON/OFF switch and wait for the
workpiece to come to a standstill.
IMPORTANT The lathe should be
reversed only if the chuck or faceplate is
locked onto the spindle thread (e.g. with
a grub screw) or when turning between
centres with the morse taper drive
centre.
Some chucks are not equipped with any
form of locking and should never be
used in reverse.
The faceplate supplied with the lathe has
two thread-locking grub screws.
Using the Lathe
Fine adjustment of the tail centre is
made by unlocking the winding handle
locking lever (by half a turn only).
Turn the winding handle to enable the
tail centre to be advanced or retracted.
It has a travel of 110mm.
To slide the tailstock along the bed, pull
up the silver tailstock locking lever.
When it is positioned where required,
clamp it firmly in place by pressing the
lever down firmly.
Page 12
The height of the tool rest can also be
adjusted, using the black locking lever.
This type of lever can be rotated to a
more convenient position, without
moving the thread, by pulling the lever
away from the thread to disengage the
ratchet teeth and then rotating it.
The tool rest can be moved along the
bed of the lathe.
To release the toolrest pull up the silver
tool rest locking lever.
The tool rest can now freely slide along
the bed, when it is positioned where
required, clamp it firmly in place by
pressing the lever down firmly.
Faceplate Turning with Head Rotated
1) Release the Headstock locking cam with the handle provided and slide it towards the centre of the
lathe bed.
2) Pull out the spring loaded head locking pin and turn the headstock through ninety degrees so that
the spindle is facing forwards. Lock the headstock with the cam handle.
3) Remove the stop pins from both ends of the lathe bed with a large flat bladed screwdriver.
4) Slide the tailstock and toolrest assemblies off the end of the bed.
5) Reposition the toolrest assembly to the left of the headstock as in the photograph.
Page 13
Using the Indexing System
The lathe is fitted with an indexing system which allows the spindle to be locked in any of 36 positions (i.e.
at 10 degree intervals). The indexing facility is useful for fluted columns, clock faces and accurate hole
placements.
Pin Position A Pin Position B Pin Position C
There are three holes in the headstock casting which will accept the Indexing Pin. These are 20 degrees
apart. The spindle has twelve holes 30 degrees apart and a combination of these will enable you to mark
your workpiece for evenly spaced features.
Pin Position A is unthreaded and will accept the unthreaded end of the Indexing Pin. This position can be
also used to lock the spindle when removing chucks, faceplates etc.
Pin positions B & C are threaded and are used in combination with the threaded end of the Indexing Pin
