Wear protective hair covering to contain ling hair. 1.2.10 ALWAYS USE SAFETY GLASSES Also use face or dust mask if cutting operation is dusty. Everyday eyeglasses only have impact – resistant lenses. They are not safety glasses. 1.2.11 SECURE WORK Use clamps or a vise to hold work when practical.
Feed work into a blade or cutter against the direction of rotation of the blade or cutter only . 1.2.20 NEVER LEAVE TOOL RUNNING UNATTENDED. TURN POWER OFF. Don’t Leave tool until it comes to a complete stop. The operation of any power tool can result in foreign objects being thrown into the eyes, which can result in severe eye damage . Always wear safety glasses or eye shields before using your Lathe . We recommend wide vision safety mask for use over spectacles , or standard safety glasses . 2.
DO ALLOW FAMILIARILY (GAINED FROM FREQUENT USE OF YOUR LATHE) TO BECOME COMMONPLACE. A CARELESS FRACTION OF A SECOND CAN ALLOW FOR SEVERE INJURY. 3.MACHINE SPECIFICATION Bench lathes are especially suitable for machining workshops, tool rooms and repairing workshops to machine shafts spindles, sleeves and disc workpieces of middle or small types. They can also be used to cut imperial, diameter and module threads. And with compact construction and reasonable composition, they can cut very well.

Fill the oil by taking off the inlet cap, which is fitted at the top on the right hand side of the apron . (D) Change gears Lubricate the change gears with thick machine oil or grease once a month . (E) Other portions There are oil inlets on input shaft bracket of gearboxs , handwheel bracket of apron , feed rod bracket of carriage , saddle , cross slide , toolpost, thread dial indicator , tailstock and the bracket which holds the leadscrew & feed rod . handing oil is required from time to time .

6.1SPINDLE SPEED CONTROL (refer to operation diagram) A. Identification before operation (1) Ensure that lubrication has been carried out in accordance with the lubrication charts. (2) When rotating the spindle, it is mechanized to the gear box and apron. Check that the forward / reverse switch (No. 1) or the knob component(No.6)( when it is mounted by option ) is in the Stop position ; the feed axis selector (No.20) and the thread cutting engagement lever (No.19) are in diseneaged position .
6.2 SPINDLE NOSE (CAM LOCK D1-4”) MOUNTING OF CHUCKS, FACEPLATES AND OTHER SPINDLE MOUNTED ATTACHMENTS Ensure that the location faces on both nose and attachment are scrupulously cleaned. Check that all the cams are in the release position (fig . 1) Mount the attachment on to the spindle nose and lock each cam by turning it clockwise using the key provided. A reference line R1 (fig .1) should be scribed on each chuck or faceplate to coincide with the reference line R on the spindle nose.
handle (No.12) The carriage is anchored by turning the carriage lock in clockwise direction. (B) Replacement of change gears. Open the end cover firstly, Then loose both the hexagon nut of the clamping bolt and the clamping screw of the swing frame to exchange the transmission shaft gear with another gear. And the change of driven gear is made by loosening the 120T and 127T gear shaft clamping nut . it is necessary for suitable backlash to intermediate the gears in both cases .

b. Thread table for metric lead screw.
(E)Threading dial indicator Threading dial indicator (No.16) is installed on the right hand side of apron. The indicator is used for thread cutting to engage with lead screw . To cut threads on the chart, close the lead screw nut at the appointed line of the dial according to the indicator chart, Ensure the appropriate dial line coincide exactly with fixed point each pass .

Bearing of headstock, longitudinal and cross feed, tool holders etc would be exmined and adjusted by hand or proper fitness. 4) Check the sensitivity & reliability of all manual control levers: To try the speed change rate function of headstock feeds and apron in gear box and inspect their starting, stopping and forward & reverse action whether they are sensitive and reliable or not.
To feel the temperature of motor bearing at the case of full load. 3) Noise and vibration: If you find the noise and vibration of the machine are abnormal or irregular. Stop the machine immediately for inspection and adjustment. 4) Quality of products: If you discover the quality of products is out of limit, stop the machine at once for finding the causes of defects. 5) Safety affairs: a. Must stop operation when you leave the machine. b. When changing main spindle speed or feeding speed stop running first.
2) Electrical system: Carefully examine the connection of all electrical wires, terminals and switches, which occasionally have been damaged by chips or others. 8.4.3SEMI-YEARLY INSPECTION: 1) Change oil in gear box: Remove the used oil from gear box of headstock, feed and replenish with fresh oil. 2) Check the wear and tear of all gears in gears and packing: Inspect the damage of all gears in various box. Spindle and bearings, and packing. Repair or replace it if necessary.
