General Safety Rules
Please operate the lathe with awareness of the potential for injury. If you have any
doubts about safety, please contact your local dealer before using.
Warning! Failure to follow the listed rules may result in serious personal injury.
TO ENSURE SAFE USE, READ THIS MANUAL BEFORE OPERATING THE TOOL.
 ALWAYS USE A FULL FACE SHIELD. A full face shield will protect your eyes and
face.
 KEEP THE WORK AREA CLEAN and have good lighting.
 WEAR PROPER APPAREL. Do not wear loose fitting clothing, gloves, neckties, rings,
bracelets or other jewelry, which may get caught in moving parts. Non-slip footwear is
also recommended. Pulled back long hair.
 DISCONNECT THE MACHINE from the power supply before servicing and changing
accessories.
 NEVER LEAVE THE MACHINE RUNNING UNATTENDED. Do not leave the lathe
unless it is turned “OFF” and completely stopped.
 USE THE RIGHT TOOL. Do not use a tool or attachment to do a job for which it was
not intended or designed.
 TIGHTEN ALL CLAMP HANDLES on the headstock, tailstock, and the tool rest before
operating the lathe.
 Before turning a large wood piece, it is advisable to reduce the excess before
mounting the stock to the lathe. When turning a large wood piece, the turner should
not stand in line with the workpiece in order to avoid being struck by a wood piece
ejected by an imbalance.
 Hold the tool handle firmly to avoid the rebound.

Introductions
Tools express thoughts, and serve as the extension of your hands. An ideal tool should
perform readily as a connection between the hand and the mind; additionally, it ought to
be pleasurable, enlightening and beautiful.
The Harvey team never stops pursuing excellence to enhance a user’s optimal working
experience. After developing the Harvey Turbo T-50/60 heavy duty woodworking lathes,
the Harvey team then spent over two years working to develop a smaller lathe ideally
sized to suit the demands of serious hobbyists and home workshops. Now we are glad to
announce that our efforts have been achieved: the Turbo T-40 Lathe is the result.
In order to overcome long known issues of insufficient torque and “speed loss” on most
small lathes on the market, for the first time in the industry, Harvey Industries has
introduced the Industrial Servo Motor (ISM) system and integrated it in with the T-40
spindle drive.
The exterior and machined surfaces are engineered and crafted with our highest
standards to enhance a user’s experience. The Turbo T-40 lathe is crafted with premium
grade cast iron and machined to the highest tolerances. The guideways are precision
ground for smooth operation. The surface of the T-40 lathe is coated with a high gloss,
stoved varnish.
The T-40 features a 360mm (14”) maximum swing, and a 625mm (24”) distance between
centers. The spindle head can rotate 90° for larger faceplate turning. In addition, 80KG
(178 lbs.) of deadweight makes the T-40 the heaviest lathe in its league. The Harvey
engineering and manufacturing teams sincerely hope the new Turbo T-40 will make a
greatly enjoyable tool for turners of all ages and skill levels.
Features
 Industrial Servo Motor drive system with 300% overload capacity
