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 360

o

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

All parts are contained in one pallet
crate.

Cut the retaining straps and
unscrew the corner brackets
before prising apart the top and
sides of the crate. Care must be
taken as they are secured with
sharp pins.

Using a 13mm spanner, remove
the two coach screws securing the
lathe to the pallet

Gently lay the lathe on its side and,
using a cross head screwdriver,
remove the two metal brackets and
discard.

If you decide to bench mount your
lathe, without permanently fixing it,
you should now attach the four
rubber feet to the same holes in
the lathe bed.

The lathe is sufficiently heavy and
stable to be used without fixing to a
base provided the workpiece is not
too large and the blank well
balanced. For larger diameter
blanks (6” plus) and unbalanced
pieces, it is recommended that the
lathe is fixed to a suitable stand or
bench.
In that case, remove the rubber
feet and mount directly using the
holes in the cast bed.

Unpack the parts carefully and
check that everything is present as
shown.

If anything is missing contact your
retailer immediately.

Assembling the Lathe

Decide where you wish to mount your lathe. Ideally, the height of the spindle should be
approximately level with your elbow when standing/sitting in a working position.

Check that the Power & Control
cables are connected to the
sockets in the rear of the Speed
Control Box.

PLEASE NOTE:
THE POWER CORD MUST
NEVER BE CONNECTED
DIRECTLY TO THE MOTOR
CABLE AS THE MOTOR IS A
DIRECT CURRENT TYPE AND
WOULD BE PERMANENTLY
DAMAGED.
