- Grounding plug should be plugged directly into a properly installed and grounded 2- prong grounding-
type receptacle, as shown.
- Do not remove or alter grounding prong in any manner. In the event of a malfunction or breakdown,
grounding provides a path of least resistance for electrical shock.
STARTING OPERATION
You can start the machine with the green ON-button.
The red OFF-button on the main switch (5) stops the machine.
Machine operation
The bench grinder is designed for grinding metal materials only without use of water.
The medium grain abrasive wheel is suitable for rough grinding where a considerable amount of metal
must be removed.
The fine grain abrasive wheel is suitable for sharpening tools and grinding to close size and smooth
finish.
Hold and guide the work piece safely during machining.
Do not perform any operation freehand; always have the work piece supported by the tool rest.
Apply a moderate pressure on the work piece and keep it moving for smooth grinding.
Pressing too hard overheats the motor and prematurely wears down the grinding wheels.
Note the original bevel angle on the item to be sharpened and try to maintain the same shape.
The grinding wheel should rotate into the object being sharpened.
Keep a tray filled with water and dip your work piece regularly to prevent overheating. Overheating can
weaken metals.
When the wheel becomes loaded of debris, use an approved grinding wheel dresser and dress the
wheel.
Warning:
The condition of the abrasive wheels should be checked before each machining process. Work only
with flawless abrasive wheels.
Do not allow anyone to stand behind the unit or close to the work piece where debris can be thrown.
Flying sparks will occur when cutting. They can cause injury and ignite flammable materials.
Use safety goggles at all times.
Use ear protection at all times.
Wear a face and dust mask when working in a dusty environment.
Ensure that the wheel guards are in the correct position before you start machining.
Keep the tool rest and spark guard to within 2mm of the grinding wheel.
Before starting the grinder, turn the wheels by hand making sure they turn freely.
Allow the abrasive wheels to reach full speed before machining.
Do not use the side of the grinding wheel; this puts dangerous stress on the wheel.
Do not stop the wheel by side pressure.
Do not touch the machined work piece until it cools or you may be burned!
Never place your hand near the cutting area while machine is in operation.
Never machine pieces that are too small to hold safely.
Support long work pieces with helping roller stands.
