Air supply connection
For correct use of the pneumatic tool, always keep to a maximum pressure of 6.2 bar, as measured at the tool inlet. Feed the
pneumatic tool with clean, condensate-free air (picture 3-a). Excessively high pressure or humidity in supply air results in shorter
life for the mechanical parts and may damage the tool.
USE
Start / Stop
To start the pneumatic tool, press the start lever (picture 4-c), and keep it pressed during the job to be performed. Releasing the
lever will cause the pneumatic tool to stop immediately.
Check the position of the ratchet reverse lever before operating the pneumatic tool, so as to know the direction of rotation.
Setting direction of rotation
The reversible air ratchet can rotate both clockwise and anticlockwise (picture 5-e). Select the direction of rotation through the
reverse lever on the ratchet:
" F " FORWARD anticlockwise (screwing) – seen from the operator's side
" R " REVERSE clockwise (unscrewing) – seen from the operator's side
Fit the required impact socket onto the male drive, and make sure that it is inserted correctly.
Adjust the speed of the pneumatic tool by turning the adjusting knob (picture 3-b).
Always disconnect the air supply before fitting in tools or making adjustments; this precaution will prevent the
pneumatic tool from being accidentally started.
Lubrication
The pneumatic tool must be connected to a filter-lubricator unit (we recommend Beta item 1919F1/4) provided with an air-oil
microfog mixer, set at two drops per minute. This will result in a high-performing tool and wear-resistant mechanical parts.
If lubrication is not provided to the line, oil ISO 32 must be periodically poured into the pneumatic tool, through the air supply
hole (picture 6-g).
MAINTENANCE
Maintenance and repair jobs must be carried out by trained personnel. For such jobs, you can contact Beta Utensili S.P.A.'s
repair centre.
DISPOSAL
The pneumatic tool, accessories and packaging should be sent to a waste disposal centre, in accordance with the laws in force
in your country.
