SAFETY INSTRUCTIONS

Read these instructions carefully before use!

• Always wear suitable eye protection. Harmful dust can be formed when working with the tool. Always wear a dust mask. Wear ear protection and gloves, if required.
• Do not overreach – always maintain a firm footing and good balance. Secure the workpiece with clamps or in a vice. Always operate the tool with both hands.
• Loose hair, jewellery, loose-fitting clothes, etc., can become caught in tools with moving parts. This can cause serious injuries.
• Keep the work area clean. Keep children and onlookers at a safe distance when using the tool.
• Make sure the workplace is well ventilated.
• Always disconnect the air hose before assembling/adjusting the tool and/or accessories.
• The tool must always be turned off when it is connected to the compressed air supply.
• Always disconnect the air hose when the tool is not in use. Switch off the tool if the compressed air supply is interrupted.
• Never carry the tool by the hose.

WARNING!

• Only use the tool for its intended purpose.

• Do not use the tool in areas where there is a risk of explosion.

• Do not overreach – always maintain a firm footing and good balance. Always wear gloves to avoid the risk of crushing injuries caused by reaction forces.

• Unexpected tool movements caused by reaction forces or tool breakages can cause personal injury.

• Loose hair, jewellery, loose-fitting clothes, ties, scarves, etc., can become caught in tools with moving parts or that drive other moving parts. This can cause serious injuries.

• Use approved ear protection if the noise level in the workplace exceeds 85 dB(A).

• Unexpected tool kickback may cause personal injury.

• Falling is a common cause of injury and death. Look out for hose bends in your area of movement and in the work area. Also look out for the part of the hose that is permanently connected to the tool.

• Excessive air pressure or excessively long operation without a load shortens tool life and can entail a risk of personal injury or damage to property.

• Continuous use and unsuitable working conditions can cause hand injury. Stop using the tool if your hands become numb or start to hurt. Do not resume work until your hands feel normal again.
  Seek immediate medical assistance if the problem persists.

• Never make any modifications to the tool. This can make the tool dangerous to use.

TECHNICAL DATA

Always wear ear protection.

The declared vibration and noise value, which has been measured by a standardised test method, can be used to compare different tools with each other and for a preliminary assessment of exposure. The measurement values have been determined in accordance with EN ISO 11148-7-2012.

WARNING! The actual vibration and noise level when using power tools may differ from the specified maximum value, depending on how the tool is used and what kind of workpiece is processed. It is therefore necessary to determine which safety precautions are required to protect the user, based on an estimate of exposure in actual operating conditions (taking into account all stages of the work cycle, e.g. the time when the tool is switched off and when it is idling, in addition to the start-up time).

OPERATION

• Use 3’’ cut-off wheels in good condition.
• Always maintain a firm footing and good balance, so that you can handle unexpected tool movements caused by reaction forces.
• Squeeze the trigger with the safety catch to start.
• Do not use the tool if you are unable to hold it firmly when working.
• Release the trigger in the event of pressure loss.

Compressed air supply

1. Check that the relevant compressor provides sufficient air flow.
2. The tool must always be turned off when it is connected to the compressed air supply.
3. 6.2 bar is the normal operating air pressure for the tool. Excessively high pressure and contaminated air cause the tool to wear unreasonably quickly, and can also entail a risk of personal injury or damage to property.
4. Drain off any water from the compressor’s air container daily. Otherwise, water from the air hoses can penetrate the tool and damage it.
5. Clean the air intake filter cartridge each week. The chart below shows the recommended connection.
6. If hoses are very long (normally longer than 8 metres), the line pressure must be increased to compensate for the pressure drop. The minimum inner diameter of the hose is 1/4”. Couplings must have the same inner diameter. An air hose with an inner diameter of 3/8” is normally recommended for optimum tool performance.
7. Use appropriate hoses and couplings. We do not recommend connecting quick-release couplings directly to the tool, as they can cause malfunction as a result of vibration. Instead, connect a hose to the tool and install a quick-release coupling between the air hose from the compressor and the anti-vibration hose that is attached to the tool.
8. Keep the hose away from heat, oil and sharp edges. Inspect each hose for wear before use. Make sure that all connections are secure.

MAINTENANCE

1. The tool can be lubricated with a line-mounted lubricating device or manually. During manual lubrication, disconnect the compressed air supply, apply a few drops of pneumatic oil in the tool’s air intake and operate the tool for a few seconds. SAE 10 oil or sewing machine oil can be used. Do not use flushing oil.
2. Before connecting the air hose, apply 4 or 5 drops of pneumatic oil in the air intake. Do not use oil with a high viscosity. This can impair tool performance.
3. Lubricate the tool after every 1 or 2 hours of operation.
4. Before putting the tool away after use, disconnect the air hose and apply 4 or 5 drops of pneumatic oil in the air intake. Reconnect the air hose and operate the tool for approx. 30 seconds todistribute the oil evenly. This will ensure the tool lasts longer.
5. Clean the air intake filter cartridge each week.

Storage

Do not store in a damp location. This can result in corrosion damage to the mechanism. Always lubricate the tool before storage.

TROUBLESHOOTING

• The tool operates slowly or at varying speeds.
• The motor is clogged.
• The tool starts on its own when the compressed air supply is connected.
• Low torque.
• Abnormal vibrations, the casing feels hot.

|

• Insufficient air flow (air pressure too low).
• Faulty speed regulator/trigger.
• Worn or damaged rotor blades.
• Dust in the motor.
• Defective trigger or trigger catch.
• Air leak at the inlet or elsewhere.
• Bearing damage.
• Corresponding O-rings are worn out or out of position.
• Insufficient lubrication.

|

• Check that the air hose is not blocked or folded.
• Check that the compressor is supplying the correct air pressure.
• Replace the rotor blades.
• Dismantle and clean the tool as instructed.
• Check and repair the trigger catch and trigger.
• Locate and seal the leak as instructed.
• Replace the bearings.
• Replace damaged O-rings. Adjust O-rings that are out of position.
• Lubricate the tool as instructed until it operates with the correct speed and torque.

NOTE! Contact your dealer if you detect a problem that is not included in this troubleshooting guide.
