casting. Do not lift using the chuck, leadscrew, or motor as contact points.
4.2 Site Requirements
Install the lathe on a solid, level concrete floor free of vibration.
Ambient temperature should remain between 41–95°F (5–35°C).
Allow at least 24" (600 mm) of clearance on all sides for access and maintenance.
4.3 Mounting the Lathe
If using a factory stand or cabinet base, align the lathe mounting holes with the stand, and secure using the
supplied hardware.
If mounting directly to a bench, ensure it can support at least 860 lbs (390 kg).
Level the lathe using leveling feet or shims under the stand/base.
4.4 Leveling the Machine
Accurate leveling ensures proper carriage travel and prevents twisting of the bed.
Tools required: 6" machinist’s precision level
1. Place the level directly on the bedways, parallel to the spindle axis (longitudinal direction).
2. Adjust the leveling feet or shim points until the bubble is centered.
3. Repeat the process across the bed (crosswise direction).
4. Recheck after 24–48 hours of use and adjust if necessary.
Do not use a carpenter’s level. Use only a precision level with sensitivity of at least 0.0005"/10".
4.5 Electrical Requirements
Voltage: 220V, 1-phase, 60 Hz
Minimum Circuit: 15A
Power Cord: Use a properly grounded plug and outlet; grounding is required.
Extension cords are not recommended.
Before powering the machine:
Ensure all switches are in the OFF position.
Confirm correct spindle rotation (clockwise facing the chuck).
If the spindle runs in reverse, switch two input wires (for models with reversible polarity).
Do not modify the electrical system. All wiring changes should be done by a qualified electrician.
