Forch 5352 3 Bedienungsanleitung Seite 19

Do not exceed the maximum value of compressed air when using the device (6.2 bar/90PSI).
The device may explode which would result in severe or lethal injuries.
5. Never exceed the specifications for the value of compressed air of any component in the compressed air circuit.
6. Always disconnect the compressed air line of the device before replacing the bits or performing repair works or if
the device is not used.
7. Wear safety goggles!
8. Do not wear any loose clothes such as scarf or tie when using the device. Loose clothes could be caught by
mobile parts and result in severe injuries.
9. Do not wear jewelry when using the device. Jewelries could be caught by mobile parts and result in severe injuries.
10. Never press the tripping device when connecting the device to the compressed air supply.
11. Only use add-on parts for the device recommended by the manufacturer. Never use defective add-on parts.
12. Never start the device without positioning the workpiece which needs to be machined.
13. Protect the compressed air lines against damages.
14. Never direct the device on yourself and other persons. Severe risk of injuries.
15. Check if there are any weak points or defects on the compressed air lines and connection. Furthermore, check
if the connections are safe. Always release compressed air from the line system before performing installation,
service or repair works.
16. Always check that all add-on parts and screws are tightened in order to guarantee the safety of the device.
17. Always keep your hands at a safety clearance from mobile parts of the device.
18. It is recommended to use an 3/8" air line between the compressor and the device.
19. Condensed water is produced in the lines and may result in malfunctions. It is recommended to install an air filter
and oil lubrication between the compressor and the device. Clean the air hose using compressed air before
connecting the device. This prevents dust and humidity from entering inside the device and avoids malfunctions
and production of rust. Increase the line pressure in order to compensate unusual lengths (of more than 7.5m).
Avoid carrying or pulling the air hose when transporting or pulling the device. Protect the compressed air hose
against heat, oil and sharp edges. Replace damaged or worn compressed air hoses.
20. The device must be lubricated before storing it. Observe the "instructions for lubrication of air motor", but have
the device only run for 2 to 3 seconds in order that more oil is preserved in the device for optimum
"conservation".
Special safety instructions
1. Information about noise level
(1) The noise level of the user is about
(2) Reference standard:
(3) Wear ear protection
2. Information about vibration level
(1) Vibration at the handle about:
(2) Reference standard:
3. Information on temperature
(1) Temperature increase on the handle (after 8 h compared with the initial temperature): 1.7 °C
4. Warning
(1) The device is not isolated against contact with current sources.
(2) If the device blocks high torque forces might occur.
A blocking might be caused by:
• Canting of the drill bit
• Excessive pressure
• Breakthrough of the drill bit on the workpiece
(3) Unexpectedly occurring torque force or breaking of the drill bit might result in injuries.
(4) Inappropriate posture might cause that it is not possible to appropriately counteract suddenly occurring torque
forces.
(5) The device must be disconnected from the compressed air before changing the drill bit.
(6) Observe the dangers when drill bits and drill chucks are rotating.
(7) Observe risk of stumbling.
(8) Observe the dangers of a defective compressed air hose slewing around.
5. Notes
(1) If you want to completely drill through a workpiece, be prepared for possible suddenly occurring of torque forces.
Immediately release the start button.
(2) Before using the device make sure that the pin spanner is removed.
(3) Only use lubricants recommended by the manufacturer.
