Unpacking and Preparing for Use (See assembly instructions)

Upon receipt, carefully unpack the lathe and inspect it to ensure that no damage was suffered in transit and to account for all parts. 
Should any damage be apparent, or parts are missing, please contact the carrier and Micro-Mark immediately.

The following loose items are to be found in the packing case (fig. 2):

4 Rubber Feet*

4 M6 pan head Screws*

4 Hex Keys

1 Chuck key

1 Plastic Oil Container

1 Spare Fuse

2 Plastic Handles w/Nuts and Bolts*

1 MT-2 Dead Center for Tailstock

3 External Jaws for 3-Jaw Chuck

2 Open End Wrenches, 8/10 mm and 14/17 mm

1 Gear Set: 65, 60, 57, 55, 50, 45, 40 (2), 35, 30

*Not shown

The machine is very heavy. With an assistant, lift it onto a sturdy surface or workbench. Remove all traces of preservative with a good quality 
solvent, then lightly oil all machined surfaces.

You will notice that, for transit purposes, the cross slide feed handle has been mounted in reverse. Remove it by unscrewing the socket head screw
that secures it, and mount it in the correct way. Then turn all feed handles to ensure they move freely, evenly and smoothly.

Attach the plastic handles to the rims of the manual feed and tailstock feed hand wheels, ensuring that the nuts are tight and the handles spin freely
around the bolts without excessive end play.

The carriage/saddle, cross-slide and compound slide adjustments are all factory set to ensure smooth movement in both directions. 
However, if the adjustments have been upset during transit (indicated by stiff or erratic movement), refer to “Settings and Adjustments” 
for the methods of adjustment.

All hex keys and wrenches necessary to carry out the various adjustments are supplied together with a chuck key for the 3-jaw chuck and 
a spare fuse (F10AL250V). The fuse holder is located on the top of the main control panel.

The four rubber feet are to be attached to the underside of the bed with the four M6 pan head screws in the tapped holes provided. 
These screws are also used to secure the chip tray. To provide maximum stability and additional safety, we strongly recommend that 
you secure the lathe to a firm foundation as described under “Mounting the Lathe” below.

The three external jaws for the 3-jaw self-centering chuck extend the capacity of the chuck and are discussed in greater detail under “Accessories.”

INSTALLATION
Mounting the Lathe

The lathe should be mounted on a sturdy workbench of sufficient height
so that you do not need to bend your back to perform normal operations.
The machine is very heavy, so get assistance from another person when
moving the machine.

Provide adequate overhead lighting so that you will not be working in
your own shadow.

We strongly recommend that the machine be firmly bolted to a sturdy
workbench using the same tapped holes used to secure the feet to the
lathe. This will provide added stability and, consequently, safety.

To do this, remove the four M6 screws which secure the rubber feet 
and chip tray to the machine (if already fitted). Remove the rubber feet.
They will no longer be used. 

Drill four 1/4” clearance holes in the bench top at the locations shown 
in fig. 3 and, with appropriate length M6 x 1.0 bolts or screws with flat washers (not supplied), secure the lathe to the worktop ensuring that the
chip tray is in place.

Alternatively, if you do not wish for a permanent installation, you may secure the lathe to a 5/8” thick plywood board with a minimum recommended
size of 12” x 32”, centering the mounting holes on the board. When the lathe is in use, the board should be clamped to workbench with C-clamps.
