Safety Instructions

These instructions must be read and understood before any operation. Any modification or update not specified in the manual should not be undertaken. The manufacturer is not liable for any injury or damage due to non-compliance with these instructions. Consult a qualified person if unsure.

General Safety

• Pressurised air can cause serious damage.
• Always stop the air flow and disconnect the tool from the line before replacing accessories, repairing, or if not in use.
• Do not direct air flow at others or yourself; maintain a safe distance.
• Check hoses and connections for damage or leaks.
• Do not use quick-change connections on the tool as they can cause loosening due to vibration.
• Do not exceed the maximum air pressure limit of 6-7 bar or the value indicated on the tool's plate.
• Handle hoses and connectors with care. Do not carry the machine by the hose. Do not pull forcefully to disconnect. Keep hoses away from heat, lubricants, and sharp edges.
• Check hoses for wear before use and ensure all connections are secure.

Risks Caused by Fragments

• Always use eye and face protection.
• Small fragments can cause eye damage and blindness.
• Pneumatic tool explosions can cause serious damage.

Avoiding Entanglement

• Maintain a safe distance from working drills, blades, and moving tools.
• Do not wear loose clothing, jewellery, or have long hair.

Risks Caused by Operation

• Wear protective gloves.
• Do not modify the tool or accessories.
• Operators must be physically capable of handling the tool's power and following procedures.
• Do not force the tool; use it at its designed speed for better performance.
• Ensure correct belt assembly to avoid injuries from loose belts.
• Do not use chipped or cracked abrasive belts.
• Use only belts that fit the machine easily.
• Before sanding, test the belt by briefly running the tool at full speed. Use a barrier to stop loose belts.
• A cracked sanding belt can cause serious injuries.
• Regularly check the unit's speed with a tachometer to ensure it is consistent with the abrasive belts used.
• Never use a belt with a speed lower than the tool's speed.
• Use only abrasive belts with appropriate diameter, dimensions, and speed.
• This tool is designed as a belt sander and should only be used for this function. Misuse can lead to serious health issues.

Dangers Caused by Working Conditions

• Slipping, tripping, and falling are major causes of accidents.
• High noise levels can cause permanent hearing damage. Use hearing protection.
• Maintain balance and firm footing. Repetitive movements, unusual positions, and vibration exposure can harm hands and arms. Stop use and consult a doctor if numbness, tingling, pain, or paleness occurs.
• This tool is not suitable for use in hazardous areas.

Safety Standards for Tool Use

• Handle the belt sander with care for long-lasting performance.
• Wear eye and ear protection, a half mask, and protective gloves.
• Use only in ventilated areas.
• Do not use in hazardous areas or near combustible materials; contact with metals produces sparks.
• Do not hold the device by the hose.
• Abrasives heat up during use; allow them to cool before touching. Disconnect the air hose when changing or adjusting abrasives.
• Do not leave the pneumatic tool running when transporting it.
• Switch off the unit immediately in case of blockage or twisting. Disconnect the air supply and do not turn on again until the problem is solved. Understand the reason for blockage and ensure it does not reoccur.
• Make sure accessories are not damaged. Replace if unsure.
• If the pneumatic tool emits strong vibration, replace the accessory/abrasive material.

Installation and Operation

Start Up

• The compressed air network must be perfectly purged and adapted to the tool's consumption. A pressure-regulator and lubricator filter of appropriate size must be installed within 10 metres of the tool (except for tools without lubrication). The regulation pressure should be set at 6.2 bar, and the specialist oil flow rate for lubricated tools should be about 1 drop of oil every 30 seconds for an air flow rate of 100 litres/mm. The tool's air consumption must be higher than the lubricator's minimum priming rate. A shut-off valve must be placed upstream.
• The connection between the filter-regulator-lubricator assembly and the tool is made via a special flexible compressed air hose (rubber or PVC) with a maximum length of 10 metres and an internal diameter of at least 8 mm for 1/4” connections and 12 mm for 3/8” connections. It must be equipped with an automatic or semi-automatic closing connection near the tool for easy disconnection.

Application

• Only use accessories in perfect condition that correspond to the tool's characteristics.
• Avoid running the tool empty. After prolonged use, ensure no accessories are attached. Disconnect the tool for accessory installation. Check that they are fitted correctly before connecting the tool.
• Regularly inspect the condition of the power supply leads. Repair any damage or leaks immediately. A broken pipe can cause serious injury. Periodically check lubricator levels, filter, and pipe purging.

Maintenance

• At the beginning of the day and before a prolonged period of no use, pour a few drops of specialist oil directly into the intake hole. Do not use flammable liquids like gasoline or diesel.
• Regularly check the condition of the regulating filter and the oil level in the air system lubricator.
• Ensure supply connections, piping, and accessories are in perfect condition. Regularly drain compressor pipes and tank. Note the expiry date for testing.
• Only original parts from the supplier may be used for maintenance.
• GYS is not responsible for modifications made to the tools or non-compliance with general safety rules for compressed air use.
