Warning 1. Read and understand the entire owners manual before attempting assembly or operation. 2. Read and understand the warnings posted on the machine and in this manual. Failure to comply with all of these warnings may cause serious injury. 3. Replace the warning labels if they become obscured or removed. 4. This lathe is designed and intended for use by properly trained and experienced personnel only.
21. Give your work undivided attention. Looking around, carrying on a conversation and “horse-play” are careless acts that can result in serious injury. 22. Maintain a balanced stance at all times so that you do not fall or lean against moving parts. Do not overreach or use excessive force to perform any machine operation. Never force the cutting action. 23. Use the right tool at the correct speed and feed rate. Do not force a tool or attachment to do a job for which it was not designed.

1 Unpacking Open shipping container and check for shipping damage. Report any damage immediately to your distributor and shipping agent. Do not discard any shipping material until the Lathe is assembled and running properly. Compare the contents of your container with the following parts list to make sure all parts are intact. Missing parts, if any, should be reported to your distributor. Read the instruction manual thoroughly for assembly, maintenance and safety instructions.
Uncrating and Cleanup 1. Finish removing the wooden crate from around the lathe. 2. Unbolt the lathe from the shipping crate bottom. 3. Choose a location for the lathe that is dry, has good lighting, and has enough room to allow servicing the lathe on all four sides. 4. Sling the lathe as shown in Figure 1, using steel rods or pipes of sufficient strength inserted through the holes in the bed casting. Do not lift lathe by the spindle.
3. Inspect the camlock studs. Make sure they have not become cracked or broken during transit. Clean all parts thoroughly with solvent. Also clean the spindle and camlocks. 4. Cover all chuck jaws and scroll inside the chuck with #2 lithium tube grease. Cover the spindle, camlocks, and chuck body with a light film of 20W oil. 5. Lift the chuck up to the spindle nose and press onto the spindle. Tighten in place by turning the camlocks 1/4 turn clockwise.
Drain oil completely and refill after the first three months of operation. Then, change oil in the apron annually. Pull knob (C, Figure 5) on the one-shot lube system and hold for several seconds to allow oil to fill the pump. When the knob is released, oil will flow through various oil lines to lubricate the ways and cross slide surface. Perform this twice daily or as needed. When the oil level is below the indicator mark, oil must be added. 4.
The main motor is rated at 7-1/2 HP (or 10HP for model 2280ZX), 230/460V and comes from the factory prewired at 230V. Confirm that power available at the lathe’s location is the same rating as the lathe. Power is connected properly when rotating the forward-reverse knob (E, Figure 12) to the left position causes the spindle to rotate counterclockwise as viewed from the tailstock.
Carriage The carriage (C, Figure 10) is made from high quality cast iron. The cross-slide (E, Figure 10) is mounted on the carriage and moves on a dovetailed slide which can be adjusted for play by means of the gibs. The compound slide (D, Figure 10) which is Tslotted, and mounted on the cross slide (E, Figure 10) can be rotated 360°. The compound slide and the cross slide travel in a dovetailed slide and have adjustable gibs.
To set the steady rest: 1. Loosen three hex socket cap screws. 2. Loosen knurled screw and open sliding fingers until the steady rest can be moved with its fingers around the workpiece. Secure the steady rest in position. 3. Set the fingers snugly to the workpiece and secure by tightening three hex socket cap screws. Fingers should be snug but not overly tight. Lubricate sliding points with lead-based grease.
4. Feed/Lead Selector Lever (H, Figure 12): Located on front of headstock. Used when setting up for threading or feeding. 5. Compound Slide (L, Figure 13) is located on top of the cross slide and can be rotated 360°. There are calibrations in degrees (M, Figure 13) below the rest to assist in placement of the compound slide to the desired angle. 6. Compound Lock (not shown): Lever located on back of compound slide. Turn clockwise to lock and counterclockwise to unlock. 7.
15. Compound Rest Traverse Handle (J, Figure 13): Located on the end of the compound slide. Rotate clockwise or counterclockwise to position. 16. Tool Post Clamping Lever (K, Figure 13): Located on top of the tool post. Rotate counterclockwise to loosen and clockwise to tighten. 17. Tailstock Quill Clamping Lever (A, Figure 14): Located on the tailstock. Rotate clockwise to lock the sleeve. Rotate counterclockwise to unlock. 18. Tailstock Clamping Lever (B, Figure 14): Lift up to lock. Push down to unlock.
Operation Feed and Thread Selection 1. Reference the feed and thread chart on the front of the headstock (A, Figure 16). 2. Move levers and knobs (B/C/D/E, Figure 16) to the appropriate position according to the feed and thread chart. Thread Cutting 1. Set forward/reverse lever (F, Figure 16) to desired direction. 2. Set selector levers (G/H, Figure 16) to desired R.P.M. [On EVS models, use lever H and the variable speed dial on the swivel control panel to select speed.] 3.
Removing Gap Section 1. To remove the gap section, remove four hex socket cap screws, and two hex cap bolts. 2. Tighten the hex nuts on the tapered alignment pins to loosen the pins. Once loosened, they can be removed. 3. Gap section can now be removed. Installing Removable Gap Section 1. Clean the bottom and the ends of the gap section thoroughly. 2. Set gap section in place and align the ends. 3. Loosen the nuts on the locating pins and push down through the gap into the lathe bed. 4.
