Machine data

Technical specifications

• Voltage 230 V
• Frequency 50 Hz
• Power input 180W S1, 250W S2
• Rotational speed, not loaded 2980/min
• Duty time S2 = 30 min
• Grinding wheel dimensions
  • Ø 150×20 mm

Load factor
A load factor of S2 = 30 min (intermittent periodic duty) means that you may operate the motor continuously at its nominal power level for no longer than the time stipulated on the specifications label (30 minutes ON period). If you fail to observe this time limit the motor will overheat. During the OFF period the motor will cool again to its starting temperature.

Vibration level
The vibration emission level stated in this instruction manual has been measured in accordance with a standardised test given in EN 62841; it may be used to compare one tool with another and as a preliminary assessment of exposure to vibration when using the tool for the applications mentioned

• using the tool for different applications, or with different or poorly maintained accessories, may significantly increase the exposure level
• the times when the tool is switched off or when it is running but not actually doing the job, may significantly reduce the exposure level

Protect yourself against the effects of vibration by maintaining the tool and its accessories, keeping your hands warm, and organizing your work patterns

Safety instructions

Explanation of symbols
Denotes risk of personal injury, loss of life or damage to the tool in case of nonobservance of the instructions in this manual.

Special safety instructions
When using the machine for the first time:

• Check the following:
  • Does the voltage rating of the bench grinder correspond to the power supply?
  • Is an earthed mains power socket available?
  • Are the power cord and plug in good condition (solid, without fraying or other damage)?
• Avoid the use of long extension cords. The extension cords you use must always be earthed.
• A grinding wheel is a brittle tool piece. The stone is not resistant to knocks.
• Always grind on the front edge of the grinding wheel, and never on the side of the grinding wheel. Never fit a cracked grinding wheel. Replace it immediately, as the high rotational speed could cause the stone to fly apart, causing a serious accident.
• Always wear safety glasses when grinding.
• Never grind without the cover fitted over the grinding wheel.
• Always fit the grinding wheel cover and tool rest tightly, and with the correct clearance.
• Never allow more than 1-1.5 mm clearance between tool rest and grinding wheel.
• Only use the grinding wheel for the work it was designed for (for example sharpening tools), and NOT for heavy construction work.
• The following information must be available, before you fit any new grinding wheel:
  • Details about the manufacturer.
  • Binding material.
  • Dimensions.
  • Permissible rotational speed.
• Never ream out the hole in a grinding wheel to a larger diameter.
• The maximum rotational speed of the grinding wheel should never be allowed to exceed the maximum speed given for the wheel.
• Never use any grinding wheel that is damaged or deformed.
• In order to be able to grind safely, the machine must be firmly bolted to a workbench.
• The tool rest should be replaced whenever the width of the tool rest measures less than 20 mm.
• The recommended depth of the recess in the flange (T) is 2 mm and the diameter of the spindle hole is 13 mm (see Fig. B).

Whenever using the machine

• Check that the switch is NOT in the ‘ON/1’ position before connecting the machine to the power supply.
• Always keep the power cord out of the way of the tool’s moving parts.

Immediately switch off the machine when:

• The plug or power cord is defective or damaged.
• The switch is defective.
• You smell smoke or burning insulation

Electrical safety
When using electric machines always observe the safety regulations applicable in your country to reduce the risk of fire, electric shock and personal injury. Read the following safety instructions and also the enclosed safety instructions. Always check that the power supply corresponds to the voltage on the rating plate.

Replacing cables or plugs
Immediately throw away old cables or plugs when they have been replaced by new ones. It is dangerous to insert the plug of a loose cable in the wall outlet.

Using extension cables
Only use an approved extension cable suitable for the power input of the machine. The minimum conductor size is 1.5 mm2. When using a cable reel always unwind the reel completely.

Installation

The grinder must be firmly bolted to a workbench. The length of the fixing bolts will depend on the thickness of the workbench. If the workbench is made of steel, it is advisable to use a wooden block or plank between the grinder and the bench, to insulate it and prevent vibration.

Assembly and adjustment of spark guard bracket and spark guard
The spark guard bracket and spark guard should only ever be assembled/adjusted with the grinding wheel stationary, and the machine disconnected from the power supply.

• Fix the spark guard bracket (4) with attached spark guard to the grinding wheel cover, using the screw provided (A).
• Set the spark guard bracket at the correct height. The clearance (B) between the wheel and the spark guard bracket should be 1 to 1.5 mm.
• Next tighten the screw (A) firmly.
• Position the spark guard to give maximum protection when working.
• Always wear safety glasses.

Fitting and adjusting tool rest
The tool rest should only be adjusted when the grinding wheel is completely stationary, and the machine is disconnected from the power supply (the wall socket).

• Fit the tool rest as shown in Fig. C.
• Fix it as tightly as possible in position, with a maximum clearance (C) of 1 to 1.5 mm between the tool rest and the grinding wheel.

Replacing the grinding wheel

• 19 mm spanner
• 8 mm spanner
• Screwdriver

Only ever replace the grinding wheel when the motor is at a standstill and the power is completely disconnected.

• Remove the grinding wheel guards using the tools listed above. The spindle nut on the right-hand side has a right-handed thread. The spindle nut on the left-hand side has a left-handed thread. Keep this in mind when you are replacing the grinding wheels.
• Loosen the nut using the correct spanner. Remove the old wheel from the spindle.
• Clean the flanges. Place one flange (A) back on the spindle, with the hollow side facing the grinding wheel. Slide the new wheel onto the spindle. Place the second flange (A) on the spindle, again with the hollow side facing the grinding wheel. Now tighten the nut on the spindle. Do not overtighten! Now refit the grinding wheel cover, and again adjust the tool rest correctly. Run the motor briefly, without grinding.

Operation

Selecting the grinding wheel
Coarse grinding wheels will in general remove the most material, and fine grinding wheels are used for finishing. If the surface is uneven, begin by using a coarse grinding wheel, and grind the workpiece until it is smooth. Next use a fine grinding wheel to remove the grooves and scratching left by the coarse wheel, and finish off the workpiece.

How to grind
To prevent the grinding surface from blocking up, avoid holding wood, lead or any other soft material or metal against the grinding wheel. To avoid creating grooves, do not press the workpiece too firmly on the grinding wheel. Use water to regularly cool the workpiece being ground. Wood chisels and the like should never be sharpened ‘blue’. Take care not to lose your grip on the object being ground, as it may suddenly become jammed between the tool rest and the grinding wheel. This can cause the stone to shatter, the motor to seize, or the workpiece to fly off, all of which can cause injury and damage. Whenever the machine has been in use for 30 minutes, it should be switched off. Allow the machine to cool down to room temperature.

• Switching the machine on
• Check that the switch is in the “OFF/0” position before connecting the machine to the power supply.
• Press the power switch into the “ ON/1” position to start your bench grinder.
• Always keep the power cord out of the way of the tool’s moving parts.

Maintenance
