Connecting of the grinder to dust extraction system
The grinder is equipped with a connector for connecting a hose. The hose must be pulled onto the connector for dust extraction
(V). At the other end of the hose impose the hole of attached bag for dust collection and secure it with a hose clamp (available
separately). The stream of air, which is created during the grinding operation, will provide dust extraction. Increase of efficiency
of dust extraction can be achieved by connecting the other end of hose to the dust extraction systems, eg. industrial vacuum
cleaner.
Attention! It is forbidden to connect the bag directly into the grinder. The rotating wheel may catch the bag.
Operation of the grinder
Make sure that the maximum speed of the equipment is higher than the speed of the grinder.
On the shield impose overlay, which is appropriate for a given task. Start the grinder and allow the disk to reach its full speed.
MAINTENANCE
Never use petrol, solvent, or other flammable liquids for cleaning of tool. Fumes may ignite, causing the explosion of tool and
serious injuries.
Solvents used for cleaning the tool handle and tool body can cause softening of seals. Thoroughly dry the tool before starting
work.
In case of any abnormality in the tool operation, the tool should be immediately disconnected from the pneumatic system.
All pneumatic system components must be protected from pollution. Pollution, which gets into the pneumatic system can destroy
the tool and other elements of pneumatic system.
Maintenance of the tool before each use
Disconnect the tool from pneumatic system.
Before each use you should implant a small amount of preservative fluid (for example wd-40) through the air inlet.
Connect the tool to the pneumatic system and run it for about 30 seconds. This will allow to distribute the preservative liquid on
the tool interior and clean it. Disconnect the tool from pneumatic system again.
A small quantity of SAE 10 oil let to the tool interior by air inlet and openings intended for that purpose. It is recommended to use
SAE 10 oil intended for maintenance of pneumatic tools. Connect the tool and run it for a short time.
Attention! WD - 40 may not serve as the appropriate lubricating oil.
Wipe the excess of oil, which is escaped by the outlets. The left oil can damage the tool sealing.
Other maintenance
Before each use of the tool you should check whether there are on the tool any visible signs of damage. Drivers, tool holders
and the spindles should be kept clean. every 6 months, or after 100 hours of work you should submit the tool for examination by
qualified personnel in repair workshop. If the tool was operated without the use of a recommended air supply system you should
increase the frequency of tool examinations.
Removal of defects
You should discontinue the tool use immediately after any failure detection. Operation with a damaged tool can cause injuries. Any
repair or replacement of the tool must be carried out by qualified personnel in authorized repair workshop.
Failure Possible solution
Let a small amount of WD-40 through the air inlet. Run the tool for a few seconds. The blades may stick to the rotor. Run the tool for
The tool has too slow
about 30 seconds. Lubricate the tool with small amount of oil. Attention! The excess of oil can cause a decrease in power of tool. In this
rotations or it does not start
case, you should clean the drive.
The tool starts and then The compressor does not provide proper air supply. The tool starts by the air collected in the tank of compressor. As the tank is
slows down emptying, the compressor has not kept pace with the refilling of air shortages. Connect the device to a more efficient compressor.
Make sure that your hoses have an internal diameter of at least such as specified in the table in point 3. Check the set point of pressure,
Insufficient power whether it is set to the maximum value. Make sure that the tool is properly cleaned and lubricated. In the absence of results, submit the
tool for repair.
Replacement parts
In order to obtain the information on spare parts for pneumatic tools, you must contact the manufacturer or its representative.
Worn tools are secondary raw materials - it is forbidden to dispose of them together with household waste because they contain
substances harmful to human health and the environment! Please actively support the cost-effective management of natural
resources and environmental protection by passing the used equipment to the point of storage for worn out devices. To reduce the
amount of disposed waste it is necessary to re-use them, recycle or recover in another form.
