SPECIFICATIONS

OVERVIEW

ASSEMBLY

INSTALLATION OF THE TOOL REST

The tool rest attaches to the inward side of the  guard and provides a surface that must be used to support the workpiece during operation. Certain types of grinding/sanding may require jigs or accessories that will be used with the tool rest to assure the proper angle of the workpiece against the wheel. Failure to install and use the tool rest can lead to serious personal injury.

To install the tool rest:

• Loosely attach the tool rests perpendicular to the belt or wheel surface with the knob bolts, 5 mm washers and hex nuts (included).
• To adjust the angle of the sanding belt tool rest, use a square or a protractor to set the angle of the tool rest in relation to the sanding belt. Adjust both tool rests approximately 1,5-3,0mm. from the grinding wheel and the sanding belt and tighten the knob bolts. (in Fig. 1) shows the correct adjustment for the tool rest at the grinding wheel.
  

SPARK GUARD & EYE SHIELD

The spark guard must be installed and positioned 3mm from the grinding wheel to minimize sparks flying towards the operator. The eye shield must be positioned between the grinding wheel and the operator’s face to protect the operator from flying debris. This is not a replacement for safety glasses!

To install the spark guard and eye shield:

• Using the included 5 mm screw and washer, install the spark guard as shown (in Fig. 2)
• Attach the eye shield to the support bracket with the included 6 mm carriage bolt and hex nut. Use the 8 mm hex bolt and washer to attach the support bracket to the grinder (Fig.2).

BELT TRACKING

Tracking the sanding belt means to center the belt on its rollers, so that it runs balanced and does not make contact with the sides of the belt cover.

To track the sanding belt:

• Disconnect the machine from the power supply.
• Rotate the grinding wheel.
• As you rotate the grinding wheel, watch how the sanding belt rides on the upper roller. If the belt is tracking properly, the sanding belt should be centered between the sides of the belt cover as shown (in Fig. 3).
• While spinning the wheel, turn the tracking control knob anti-clockwise to make the belt move to the left, or turn the tracking control knob clockwise to make the belt move to the right.
• After the belt is centered, spin the grinding wheel approximately ten times to ensure that the belt continues to track properly.

DUST/CHIP EXTRACTION

Dust from materials such as lead-containing coatings, some wood types, minerals and metal can be harmful to one’s health. Touching or breathing-in the dust can cause allergic reactions and/or lead to respiratory infections of the user or bystanders. Certain dust, such as oak or beech dust, is considered carcinogenic, especially in connection with wood-treatment additives (chromate, wood preservative). Materials containing asbestos may only be worked by specialists.

Provide for good ventilation of the working place.

• It is recommended to wear a P2 filter lass respirator.
• Observe the relevant regulations in your country for the materials to be worked.
• Avoid dust accumulation at the workplace.
• Dust can easily ignite

OPERATION

Pay attention to the mains voltage. The voltage of the power source must match the voltage specified on the rating plate of the power tool.
Always check abrasive tools before using them.
The abrasive tool must be fitted properly and be able to move freely. Carry out a test run for at least one minute with no load. Do not use abrasive tools that are damaged, run untrue or vibrate during use.

SWITCHING ON/OFF

• To start the power tool, push the on/of switch (4) into position “I”.
• To switch off the power tool, push the on/off switch (4) into position “0”.

WORKING ADVICE

• Switch the power tool on before bringing the workpiece into contact with it and only switch the power tool off after you have removed the workpiece. The workpiece can move suddenly.
• Never reach into the power tool grinding wheel when it is running. This can lead to serious injuries.
• Wear a work apron. Ensure that no persons are at risk due to flying sparks. Remove combustible materials from the surrounding area. Flying sparks are created when sanding metals.
  Use silicon carbide grinding discs C (accessory) when working carbide (TC) workpieces.
  Place the workpiece you intend to grind onto the tool rest (5) and press it lightly against the grinding wheel. To achieve optimal grinding results, move the workpiece gently back and forth. This also ensures that the grinding wheel is worn off evenly.
  Cool off the workpiece in water at intervals

SANDING

To sand a workpiece:

• Before starting the machine, adjust the angle of the tool rest so your workpiece is supported and the area you wish to sand is parallel with the sanding belt as illustrated (in Fig 4).

• With the machine plugged into power, the red switch to the ON position.
  

• Grasp the workpiece tightly and properly support it on the tool rest.

• Press the workpiece evenly against the sanding belt with light pressure (see Fig 7 and 8). DO NOT press hard. Let the rotation of the belt do the work.
  
  

• Remove your workpiece regularly to check the progress the sander has made. Remember you can always remove more material but you cannot add it.

• When you are finished sanding, move the red switch to the OFF position. DO NOT continue sanding and DO NOT manually stop the sanding belt with your workpiece.

REPLACING WHEELS

  WARNING! The hazards of using a damaged wheel include flying chunks of sharp abrasive material that could cause serious injury or death. Inspect every grinding wheel before it is mounted and DO NOT use a damaged grinding wheel!

To remove/mount a wheel:

• Disconnect the grinder from the power supply.
• Remove the head screws and nuts that go through the outer guard. Take off the outer guard and the rim guard.
• Use a wrench on the nut that holds the wheel on the arbor. Hold the wheel to prevent it from turning with your other hand. The grinding wheel arbor has a left handed thread. Loosen the nut by turning it clockwise.
• Remove the outer wheel flange and paper disc. Pull the wheel free from the arbor. There will also be a paper disc and a wheel flange on the back side of the wheel which should also be removed.
• Mount the new wheel in the reverse order. Always make certain there is are paper or fiber discs between the wheel flanges and the wheel itself. Tighten the nut snugly but DO NOT over tighten.
• Over tightening can crack the wheel.
• Re-install the guards and shields.
• Run a new wheel for at least one minute while standing clear of the line of rotation.
• If a wheel does have defects it will generally fail as soon as it gets up to full speed

REPLACING SANDING BELT
