18. MAINTAIN TOOLS IN TOP CONDITION. Keep tools sharp
and clean for best and safest performance. Follow
instructions for lubricating and changing accessories.
19. NEVER STAND ON TOOL. Serious injury could occur if the
tool is tipped or if the cutting tool is accidentally contacted.
20. REMOVE ADJUSTING KEYS AND WRENCHES. Form a
habit of checking to see that keys and adjusting wrenches
are removed from tool before turning it on.
21. DO NOT OVERREACH. Keep proper footing and balance at
all times.
22. DIRECTION OF FEED.Mind the direction of
spindle/chuck/work to ensure a safe environment.
23. PAY ATTENTION TO WORK. Concentrate on your work. If
you become tired or frustrated, leave it for a while and rest.
24. SECURE WORK. Use clamps or a vice to hold work when
practical. Severe injury or death can occur if an object comes
free as it can become a dangerous projectile.
25. CHECK DAMAGED PARTS. Before further use of the tool,
any part that is damaged should be carefully checked to
ensure that it will operate properly and perform its intended
function. Check for alignment of moving parts, binding of
moving parts, mounting, and any other conditions that may
affect its operation. Any damaged part should be properly
repaired or replaced.
26. DRUGS, ALCOHOL, MEDICATION. Do not operate
machine while under the influence of drugs, alcohol, or any

4.Setup and Assembling the Lathe
Workshop Environment
Your workshop should set up appropriately for you to effectively use the lathe. The workshop should be setup with
the following factors taken into consideration:
1.Lathe location
Locate the NOVA 15” lathe close to a power source in an area with good amount of lighting.
Leave enough clearance when the lathe headstock is swiveled around. Other machines in the
workshop should not interfere with the movement/operation of the lathe.
2.Lighting
The workshop should have adequate lighting. There should be enough lighting around the lathe
not to cast shadows upon the workpiece. A portable spotlight might be helpful.
3.Electrical
The NOVA 15” lathe requires an appropriate power outlet nearby to power the motor. The
outlet wiring must meet the local electrical safety standards. If in any doubt, seek advice from
an electrician. The length of an extension cable should be reduced as must as possible.
4.Ventilation
Workshop must have an adequate level of ventilation. The level of required ventilation depends
on the size of the workshop and the amount of work that is done within the workshop. The use
of dust collectors and filters will minimize your health risk.

Warning!
Improper power connection may result in a risk of electrical hazard.
Before plugging the NOVA lathe into the power source, check that the:
1. The main power switch is turned off.
2. Power source is switched off.
Note: This image on the left-hand side is the European version of the NOVA wood lathe. Other versions will have a
hard-wired power cable (shown on the image on the right-hand side).
The power cord that is installed on the NOVA lathe will have a three-prong plug which includes a ground prong. The plug
must be connected to a matching outlet that his properly installed and grounded in accordance with local electrical
codes.
For 110V Outlet Only:
A temporary adapter can be used to plug into a two-pole outlet if a three-prong outlet is unavailable in your environment.
The ground tab on the adapter must be connected to the screw on the outlet for proper grounding. This adaptor should
only be used until a qualified electrician can install a properly grounded outlet.
➢Note: If an extension cable is required, make sure to check the following:
1. Extension cable gauge is appropriate for the length and voltage.
2. Is the cable properly insulated?
If in any doubt, please contact your local electrician to inspect the cord according to the local electrical standards before
use.
IMPORTANT:
•A surge protection device is recommended when using the lathe.
•A surge protection device must be rated to at least 15A should be used in countries where 110V are used
as a standard. In countries where 240V is used, a surge protector must be rated to 10A.

5.1 Ground Fault Interrupters (GFI)
For a GFI to be compatible with the DVR motor, it is recommended have a leak current threshold rating of 30mA
(0.03A)
Note: Normal household GFI will typically be rated at 5mA (0.005A) which may trigger
during the operation of the DVR motor. However, frequent tripping of the GFI will not
cause any harm to the DVR motor or its control electronics as it has a built-in
protective circuit to prevent damage from frequent switching.
5.2 Input Voltage Selection
The NOVA lathe is capable of handling both 110V and 220V without any changes to its internal circuits.
The lathe will automatically recognize the input voltage to the lathe and adjust the output power. Simply change the
