NOTICE is used to address practices not related to personal injury. Save This Manual Keep this manual for the safety warnings and precautions, assembly, operating, inspection, maintenance and cleaning procedures. Write the product’s serial number in the back of the manual near the assembly diagram (or month and year of purchase if product has no number). Keep this manual and the receipt in a safe and dry place for future reference.
c. Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury. Unmodified plugs and matching outlets will reduce risk of electric shock. b. Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is grounded. d. Do not overreach. Keep proper footing and balance at all times.
. tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users. 3. Use a brush or compressed air to remove metal shavings; never your hands. The metal shavings will be sharp. e. Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools. 4.
avoid electrical shock. • Any power cord must be properly grounded. Ground Fault Circuit Interrupter (GFCI) should also be implemented – it prevents sustained electrical shock. 13. Some dust created by power sanding, sawing, grinding, drilling, and other construction activities, contains chemicals known [to the State of California] to cause cancer, birth defects or other reproductive harm.
2. 3. Grounded tools require a three wire extension cord. Double Insulated tools can use either a two or three wire extension cord. As the distance from the supply outlet increases, you must use a heavier gauge extension cord. Using extension cords with inadequately sized wire causes a serious drop in voltage, resulting in loss of power and possible tool damage. (See Table A.) The smaller the gauge number of the wire, the greater the capacity of the cord.

Maintenance And Servicing Lubrication Procedures not specifically explained in this manual must be performed only by a qualified technician. To prevent serious injury from accidental operation: Turn the Power Switch of the tool to its “OFF” position and unplug the tool from its electrical outlet before performing any inspection, maintenance, or cleaning procedures. 1. Lubricate the Apron through the fittings on the front face with ISO 68 or SAE 20W oil. 2.
6. Wipe down the ways and slides after each use and lubricate with white lithium grease. 7. Applying oil to the bedways and other metal parts will protect the Lathe from rusting and pitting. PLEASE READ THE FOLLOWING CAREFULLY 3. Lubricate the Gearbox through the four oil caps. Add a few squirts of oil every three hours of use. 4. Lubricate the leadscrew and leadscrew bearing frequently. 5. Lubricate the tailstock oiling point every five uses, or once per week if used frequently.
