INSTRUCTIONS FOR USE ISTRUZIONI PER L'USO
DIE GRINDER USE AND CARE
- Use clamping devices or a vice to secure and support the workpiece. Holding the workpiece by hand or against your body will
not allow for safe operation of the pneumatic tool.
- Do not overload the pneumatic tool. Use the pneumatic tool intended for your work only
- Always check that the machine is free from defects. Do not use a pneumatic tool that has a defective On/Off switch. A pneumatic
tool that can no longer be stopped or started is dangerous and must be repaired
- Disconnect the air supply before making adjustments, changing accessories, or placing the grinder aside. This safety measure
prevents accidental starting of the pneumatic tool.
- Before using the grinder, remove the adjusting tools, since these may be projected at high speed.
- Store idle pneumatic tools out of the reach of children. Do not allow persons unfamiliar with these instructions to operate the
pneumatic tool.
- Maintain the pneumatic tool with care. Check for misalignment or binding of moving parts, breakage of parts and any other
condition that may affect the operation of the pneumatic tool. Have damaged parts repaired before using the pneumatic tool.
- Check that the grinder is in good condition. Make sure that the spindle and its threads are neither damaged nor worn.
- Before each use, make sure that the grinding wheel is in good condition and fit for the required job. It must not show any
damage, splinters, cracks etc.
- Check that the number of revolutions shown on the abrasive wheel (or on the packaging) matches or exceeds the number of
revolutions shown on the grinder.
- Make sure that no other people are near the tool.
- Periodically check that the speed of the grinder does not exceed the speed stated by the supplier. This check must be performed
without the grinding wheel.
- When the grinding wheel stops, place the grinder in a firm and safe position. The grinding wheel does not stop immediately
- Only use grinding wheels suitable for the required job, like:
• grinding wheels for smoothing surfaces
• grinding wheels for removing burrs and/or scraps
- Do not modify the air grinder. This can reduce the effectiveness of safety measures and increase operator risk.
- Have the air grinder repaired only through a qualified repair person. Only use original replacement parts.
DIE GRINDER SAFETY
- Check whether the nameplate is readable; if it is not, get a replacement nameplate from the manufacturer.
- The air grinder may stop if:
• It is overloaded.
- If the grinding wheel gets jammed, stop the grinder immediately, keeping it idle until the grinding wheel is fully unlocked. Do not
attempt to pull out the grinding wheel while in operation. Before resuming work, make sure that the grinding wheel has been
fixed properly and is not damaged.
- If the workpiece or the grinding wheel should break, loose parts may be thrown at high speed.
- Pay attention to grinding sparks, which may be potential hazards to exposed things and people. They may set clothes on fire
and cause burns.
- Operators and maintenance personnel should be physically able to handle the weight and power of the pneumatic tool.
- It is important to be prepared for unexpected movements of the grinder resulting from a jammed or broken wheel. Maintain a
firm grip on the grinder and position your body and arms to allow you to resist such movements.
- Keep your hands away from the grinding wheel: you may hurt yourself.
- Stop the tool in case of air supply failure or low operating pressure. Check the operating pressure; start the tool again when
optimal operating pressure is resumed.
- When using the pneumatic tool, the operator may experience discomfort in the hands, arms, shoulders, or neck area. Adopting
a comfortable posture and changing posture may help avoid discomfort and fatigue.
Caution: If the pneumatic tool is used over a protracted period of time, part of the tool and the accessory may become
hot. Wear suitable protective gloves against physical agents.
Dust and fumes hazards: Depending on the type of material being worked, the fumes generated while operating the
pneumatic tool can cause diseases in humans. An appropriate environmental hygiene survey is required to determine the
type and degree of protection of the personal protective equipment to use for the respiratory tract.
Using the pneumatic tool on the workpiece generates noise, which may prove harmful to the exposed personnel. A proper
phonometric survey is required to determine the personal hearing protective equipment (hearing protection) to use.
If a specially conducted survey suggests that the daily exposure to vibration generated from the pneumatic tool exceeds
the limit value under the regulations in force in the respective country, anti-vibration gloves must be worn.
- If you notice that the skin of your fingers becomes numb, turns white, tingles or hurts, stop working with the air saw, inform your
employer and seek medical advice.
- Do not make the grinding wheel jump on the workpiece: this may result in significantly increased vibration.
- Hold the pneumatic tool with a secure yet not too firm grip, compliant with the required hand reaction forces.
- Never carry the air saw by the hose
