Symbols |
END202-2 |
The following show the symbols used for the tool. Be sure that you understand their meaning before use.
............. Read instruction manual.
............. DOUBLE INSULATION
............. Wear safety glasses.
Intended use
The tool is intended for grinding, sanding and cutting of metal and stone materials without the use of water.
Power supply
The tool should be connected only to a power supply of the same voltage as indicated on the nameplate, and can only be operated on single-phase AC supply. They are double-insulated in accordance with European Standard and can, therefore, also be used from sockets without earth wire.
For public low-voltage distribution systems of between 220 V and 250 V.
Switching operations of electric apparatus cause voltage fluctuations. The operation of this device under unfavorable mains conditions can have adverse effects to the operation of other equipment. With a mains impedance equal or less than 0.27 Ohms it can be presumed that there will be no negative effects. The mains socket used for this device must be protected with a fuse or protective circuit breaker having slow tripping characteristics.
ADDITIONAL SAFETY RULES
ENB031-6
1.Always use eye and ear protection. Other personal protective equipment such as dust mask, gloves, helmet and apron should be worn.
2.Always be sure that the tool is switched off and unplugged before carrying out any work on the tool.
3.Keep guards in place.
4.Use only wheels with correct size and wheels having a maximum operating speed at least as high as the highest No Load Speed marked on the tool’s nameplate. When using depressed center wheels, be sure to use only fiberglass reinforced wheels.
5.Check the wheel carefully for cracks or damage before operation. Replace cracked or damaged wheel immediately.
6.Observe the instructions of the manufacturer for correct mounting and use of wheels. Handle and store wheels with care.
7.Do not use separate reducing bushings or adaptors to adapt large hole abrasive wheels.
8.Use only flanges specified for this tool.
9.Do not damage the spindle, the flange (especially the installing surface) or the lock nut. Damage to these parts could result in wheel breakage.
10.For tools intended to be fitted with threaded hole wheel, ensure that the thread in the wheel is long enough to accept the spindle length.
11.Before using the tool on an actual workpiece, test run the tool at the highest no load speed for at least 30 seconds in a safe position. Stop immediately if there is any vibration or wobbling that could indicate poor installation or a poorly bal-
4
anced wheel. Check the tool to determine the cause.
12.Check that the workpiece is properly supported.
13.Hold the tool firmly.
14.Keep hands away from rotating parts.
15.Make sure the wheel is not contacting the workpiece before the switch is turned on.
16.Use the specified surface of the wheel to perform the grinding.
17.Do not use cutting off wheel for side grinding.
18.Watch out for flying sparks. Hold the tool so that sparks fly away from you and other persons or flammable materials.
19.Pay attention that the wheel continues to rotate after the tool is switched off.
20.Do not touch the workpiece immediately after operation; it may be extremely hot and could burn your skin.
21.Position the tool so that the power cord always stays behind the machine during operation.
22.If working place is extremely hot and humid, or badly polluted by conductive dust, use a short-cir- cuit breaker (30 mA) to assure operator safety.
23.Do not use the tool on any materials containing asbestos.
24.Do not use water or grinding lubricant.
25.Ensure that ventilation openings are kept clear when working in dusty conditions. If it should become necessary to clear dust, first disconnect the tool from the mains supply (use non metallic objects) and avoid damaging internal parts.
26.When use cut-off wheel, always work with the dust collecting wheel guard required by domestic regulation.
27.Cutting discs must not be subjected to any lateral pressure

FUNCTIONAL DESCRIPTION
CAUTION:
•Always be sure that the tool is switched off and unplugged before adjusting or checking function on the tool.
Shaft lock (Fig. 1)
CAUTION:
•Never actuate the shaft lock when the spindle is moving. The tool may be damaged.
Press the shaft lock to prevent spindle rotation when installing or removing accessories.
Switch action (Fig. 2)
CAUTION:
•Before plugging in the tool, always check to see that the switch trigger actuates properly and returns to the “OFF” position when released.
For tool with the lock-on switch
To start the tool, simply pull the switch trigger (in the B direction). Release the switch trigger to stop. For continuous operation, pull the switch trigger (in the B direction) and then push in the lock lever (in the A direction). To stop the tool from the locked position, pull the switch trigger fully (in the B direction), then release it.
For tool with the lock-off switch
To prevent the switch trigger from accidentally pulled, a lock lever is provided.
To start the tool, push in the lock lever (in the A direction) and then pull the switch trigger (in the B direction). Release the switch trigger to stop.
For tool with the lock on and lock-off switch
To prevent the switch trigger from accidentally pulled, a lock lever is provided.
To start the tool, push in the lock lever (in the A direction) and then pull the switch trigger (in the B direction). Release the switch trigger to stop.
For continuous operation, push in the lock lever (in the A direction), pull the switch trigger (in the B direction) and then push the lock lever (in the A direction) further in.
To stop the tool from the locked position, pull the switch trigger fully (in the B direction), then release it.
NOTE:
Models GA7020S, GA9020S, GA7020SF and GA9020SF begin to run slowly when they are turned on. This soft start feature assures smoother operation and less operator fatigue.
ASSEMBLY
CAUTION:
•Always be sure that the tool is switched off and unplugged before carrying out any work on the tool.
Installing side grip (handle) (Fig. 3)
CAUTION:
•Always be sure that the side grip is installed securely before operation.
Screw the side grip securely on the position of the tool as shown in the figure.
Installing or removing wheel guard (Fig. 4)
CAUTION:
•The wheel guard must be fitted on the tool so that the closed side of the guard always points toward the operator.
Mount the wheel guard with the protrusion on the wheel guard band aligned with the notch on the bearing box. Then rotate the wheel guard around 180 degrees counterclockwise. Be sure to tighten the screw securely.
To remove wheel guard, follow the installation procedure in reverse.
