equipment to rain. Keep work area well lit. Do not use tools in the presence of flammable gases or liquids.
4.Keep children away. All children should be kept away from the work area.
5.Guard against electric shock. Prevent body contact with grounded surfaces such as pipes, radiators, ranges, and refriderator enclosures.
6.Stay alert. Never operate equipment if you are tired.
7.Do not operate the product if under the influence of alcohol or drugs. Read warning labels on prescriptions to determine if your judgment or reflexes might be impaired.

13.Always check that adjusting keys and wrenches are removed from the tool or machine work surface before plugging it in.
14.Do not carry any tool with your finger on either the start button or trigger.
15.When servicing, use only identical replacement parts.
Before Operation
1.Be sure the switch is OFF when not in use and before plugging in.
2.Do not attempt to use inappropriate attachments in an attempt to exceed the tool’s capacity. Approved accessories are available from Harbor Freight Tools.
3.Check for damaged parts. Before using any tool, any part that appears damaged should be carefully checked to determine that it will operate properly and perform its intended function.
4.Check for alignment and binding of all moving parts, broken parts or mounting fixtures and any other condition that may affect proper operation. Any part that is damaged should be properly repaired or replaced by a qualified technician.
5.Do not use the tool if any switch does not turn off and on properly.
Operation
1.Never force the tool or attachment to do the work of a larger industrial tool. It is designed to do the job better and more safely at the rate for which it was intended.
2.Do not carry the tool by its power cord.
3.Always unplug the cord by the plug. Never yank the cord out of the wall.
4.Always turn off the machine before unplugging.
IF THERE IS ANY QUESTION ABOUT A CONDITION BEING SAFE OR UNSAFE, DO NOT OPERATE THE TOOL!
Check to see if your tool has a two or threeprong plug. If your tool has a two-prong plug, you may proceed past the next paragraph. If your tool has a three-prong plug, please continue reading the following precautions and instructions.
If the tool or machine has a three-prong plug, the third (round) prong is the ground. Plug this cord only into a three-prong receptacle. Do not attempt to defeat the protection the ground wire provides by cutting off the round prong. Cutting off the ground will result in a safety hazard and void the warranty.

Extension Cords
If your tool is double insulated and has a two-prong plug, you may use either a two or three-prong extension cord. If your tool has a grounded, three-prong plug, you must use a three-prong extension cord with three-prong receptacles. Only use rounded jacket extension cords listed by the Underwriters Laboratories (UL). If you are using the tool outdoors, use an extension cord rated for outdoor use (signified by “WA” on the jacket).
The extension cord must have a minimum wire size depending on the amperage of the tool and the length of the extension cord. The size is determined by itsAWG (American Wire Gauge) rating. The smaller the gauge, the greater the cable’s capacity. The amount of cords used does not matter. Total length determines the minimumAWG rating. Every cord must meet theAWG rating. Use the chart below to determine whatAWG rating is required for your situation. Cord length is rated in feet. Harbor Freight Tools can supply UL listed and outdoor rated extension cords in multipleAWG ratings if needed.

Additional Safety Rules for Mini Lathe
1.Before turning on the motor, make sure that proper lubrication is included (see page of this manual).
2.Always dismount the chuck and lathe’s face plate by hand. Do not use power tools to perform these tasks.
3.After the chuck is installed, remove the wrenches and tools to eliminate the possibility of accident when the lathe is turned on.
4.Never adjust or fix workpieces or any rotating parts when the lathe is on. Never use instruments to measure the workpiece
when the lathe is on. Never check the sharpness of the cutter by using your hand. 5. Avoid accidents resulting from broken workpieces. Never use an excessively large tool cutter to do feeding with a large
workpiece.
6.Never change the gear when the lathe is in operation.
7. Always keep a safe distance from the lathe to minimize the risk of being struck by a broken workpiece.
