Grounding and insulation
-
In the event of a malfunction or break-down, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This tool is equipped with an electric cord having an equipment -grounding conductor and a grounding plug. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordination.
-
Do not modify the plug provided even if it will not fit the outlet, have the proper outlet installed by a qualified electrician.
-
Improper connection of the equipment grounding conductor can result in a risk of electric shock. The conductor with insulation having an outer surface which is green with or without yellow stripe is the equipment-grounding conductor. If
repair or replacement of the electric cord or plug is necessary, do not connect the equipment-grounding conductor to a live terminal. -
Check with a qualified electrician or serviceman if the grounding instructions are not completely understood, or if in doubt as to whether the tool is properly grounded.
-
Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles that accept the tool’s plug.
-
Repair or replace damaged or worn cord immediately.
Note:
The type of electrical plug and receptacle differs from country to country.
Adjustment and preparation
-
clean off grease on the machine.
-
check that the 3 set screws of the chuck are tight.
-
turn the chuck by hand and check if it rates freely.
-
move the feeding direction selector from the back of the body to the middle.
-
first shut off the switch 1. adjust the switch 3 by turning to “O”position and turn the switch 2 to STOP position. If the lathe needs to be started, turn the switch 1 according to direction marked on switch 2 to FORWARD or REVERSE position.
The spindle will turn immediately by turning the switch 3. The speed can be adjusted by turning the switch 3. If the lathe needs to be stopped, turn the switch 3 must be stopped, turn the switch 3 to “O”position. If the direction of the lathe spindle needs to be changed, the switch 3 must be turn to “0” position at first. If the lathe must be stopped under emergency situation, please put down the switch 1 immediately. If the lathe needs to be stared again, please do it again according to above mentioned process.(SEE ig.4)

Operation & Replacement
Replacement of chuck
When replacing the chuck, place a cloth or a piece of wood on the bed way at
the bottom of the chuck. This is to avoid damage to the bed way caused by
carelessly dropping the chuck. Loosen the 3 set screws as shown in Fig.6 (A)
to replace the chuck.
Replacement of jaws
The jaws are of two types: the internal jaws and the external jaws. Please
note that the number of jaws fit with the number inside the chuck’s groove. Do
not mix them together. When you are going tomount them, please mount them in
ascending order 1-2-3, when you are going to take them out, be sure to take
them out in descending order (3-2-1) one by one. After you finish this
procedure, rotate the jaws to the smallest diameter and check that the three
jaws are well fitted. If not you need to reassemble them again as they are not
properly assembled (Fig.7). When you are going to mount the work piece you
need only to loosen one jaw. However, we recommend you loosen the three jaws
at the same time, in this way you can protect them and will not hurt the
thread inside.
Compound rest adjustment
Loosen the two screws as shown in (A) of Fig.8. After you have obtained the
angle you demand, please do not forget to tignten them.

WBL1835-Variable-Speed-Mini-Lathe-Fig-7.png) When you are going to change
position or replace the tailstock you need to loosen the Handle in (A) of
Fig.9.
Tool post adjustment**
When you are going to adjust the tool post position, you only need to loosed the lever shown in (B) of Fig. ll. After you have finished be sure to tighten. If you are going to replace the work cutter then you need to loosen the screws of (A) with the allen wrench provided.
Operation
Fig.13 Workpiece Holding And Drilling
Use the chuck to hold the workpiece firmly. Then, use the centre to fix the
other end, if you change the center to drilling chuck you can start your
drilling immediately. (Fig. 13) Use the chuck to hold the workpiece firmly and
the cutter to start lathe’s face cutting as shown in Fig, 14 (edge of the
cutter must be at the same height as the center).
By changing the tool post angle and adjusting the compound rest, you can do internal cutting as in Fig. 15. After adjusting the angle of the compound rest, you can do bevel cutting as in Fig. 16

New SAFETY RULES for Stationary Power
Tools
follow them for best results and full benefit from shop machines
very good craftsman respects the tools with which he works. He knows they
represent years of constantly improved design. He also knows that they are
dangerous if misused. This is the theme of a new safe-use program developed by
the Power Tool institute, Inc., for stationary power tools. The institute has
put together a list of safety rules, based on ap-proved practices in
industrial and home shops, to accompany a set of new standards for sta-tionary
power tools that members of the in-stitute manufacture.
-
Know your power tool. Read the owner’s manual carefully. Learn its applications and limitations, as well as the specific potential hazards peculiar to this tool.
-
Keep guards in place and in working order.
-
Ground all tools. If tool is equipped with three-prong plug, it should be plugged Into a three•hole electrical recep-tacle. If an adapter is used to a accommodate a two•Prong re• ceptacle, the adapter wire must be attached to a known ground New- re:nove the third prong.
-
Remove adjusting keys and wrenches Form habit of check-ing to see that keys and adjusting wrenches are removed from tool before turning it on.
-
Keep work area clean. Cluttered are-as and benches invite accidents
-
CAvoid dangerous environment Don’t use power tools in damp or wet locations or expose them to rain, Keep your work area well lighted.
-
Keep children away All visitors should be kepi a sale distance from work area
-
SMake workshop kidproof — with pad-locks, master switches, or by removing starter keys
-
Don’t force tool. It will do the job better and be safer at the rate for which it was designed.
-
CUse right tool. Don’t force tool or attachment to do a job it was not designed for.
-
Wear proper apparel Wear no loose clothing, gloves, neckties, rings, bracelets, or other jewelry which may get caught in moving parts. Non-slip footwear is recommended. Wear protective hair covering to contain long hair.
-
Always use safety glasses. Also use face or dust mask if cutting operation is dusty. Every-day eyeglasses only have impact resistant lenses. They are NOT safety glasses.
-
Secure work. Use clamps or vise to hold work, when practial. It’s safer than using your hands and it frees both hands to operate tool
-
Don’t overreach. Keep proper footing and balance at all times
-
Maintain tools with care Keep tools sharp and clean for best and • safest per-formance. Follow instruc-tions for lubricating and changing accessories.
-
Disconnect tools before servicing and when changing accessories such a blades, bits, cutters and the like.
-
Use recommended accessories. Consult owner’s manual for recom-mended accessories Use of improper accessories may cause risk of injury to persons.
-
Reduce the risk of un-intentional starting. Make sure switch is in oft position before plugging in
