Maintenance - YATO YT-0920 Handbuch

MAINTENANCE

Never use petrol, solvents or other infl ammable liquids to clean the tool. The fumes may ignite and cause an explosion of the
tool and serious injuries. Solvents used to clean the handle of the tool and its body may cause softening of the sealing. Dry the
tool thoroughly before the work is commenced.
In case of any irregularities in the operation of the tool, it must be immediately disconnected from the pneumatic system.
All the elements of the pneumatic system must be protected from contamination. The contamination in the pneumatic system
may damage the tool and other elements of the pneumatic system.
Maintenance of the tool before each use
Disconnect the tool from the pneumatic tool.
Before each use, it is necessary to place a small amount of maintenance liquid (e.g. WD-40) in the air inlet.
Connect the tool to the pneumatic system and set it in motion for approximately 30 seconds in order to distribute the
maintenance liquid inside the tool and clean it.
Disconnect the tool from the pneumatic tool again.
Place a small quantity of SAE 10 oil inside the tool through the air inlet and special holes. It is recommended to use SAE 10 oil
designed for maintenance of pneumatic tools. Connect the tool and set it in motion for a while.
Attention! WD-40 may not be used as the proper lubricating oil.
Wipe off the excess of oil which comes out of the outlet openings. The remaining oil may damage the sealing of the device.
Other maintenance actions
Before each use of the tool, it is necessary to check whether there are any signs of damage of the tool. Drivers, tool holders
and spindles must be kept clean.
Every six months or after 100 hours of operation, the device must be revised by qualifi ed personnel in a repair shop. If the tool
has been used without the recommended air supply system, then it is necessary to increase the frequency of such controls.
Repairs
Operation of the machine must be interrupted immediately if any defects have been detected. Work with a defective machine
may cause injuries. All repairs or replacements of the elements of the tool must be realised by qualifi ed personnel in an
authorised repair shop.
Damage
The air blown out of the slots at the top of
the tool or around the trigger
The tool does not start or works slowly
Frequent jamming of the tool.
Insuffi cient power
Once the functioning has been concluded, the casing, ventilation slots, switches, additional handle and protections must be
cleansed with a stream of air (at a pressure not exceeding 0.3 MPa), with a brush or a cloth without any chemical substances
or cleaning liquids. Tools and handles must be cleansed with a clean cloth.
Worn tools are recyclable waste – it is prohibited to dispose of them throwing them away along with domestic waste, since
the tools contain substances that are harmful for people and the environment! We ask for your active assistance in economic
management of natural resources and protection of the natural environment by sending the tools to a worn tools disposal point.
In order to reduce the quantity of waste that is disposed if, it is necessary to recycle them.
O P
Possible solution
Check whether the screws are not loosened. Check the condition of the sealing.
The compressor does not guarantee the appropriate air supply. Connect the device to a more effi cient compressor.
Insuffi cient lubrication. Check the condition of the sealing.
Incorrect or damaged connecting elements. The dispenser is dirty and does not guarantee appropriate supply of
connecting elements.
Make sure the hoses have the correct internal diameter which must correspond at least to the value specifi ed in the
table. Check the adjustment of pressure; it must be set to the maximum acceptable value. Make sure the tool has been
properly cleaned and lubricated. If the problem persists send the tool for repair.
