KEY TO SYMBOLS

a: Air inlet 1/4" GAS
b: "butterfly" trigger
c: Power adjustment
d: Oil lubrication
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 1-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 air impact wrench, press the "butterfly" trigger (picture 3-b), and keep it pressed during the job to be performed.
Releasing the trigger will cause the pneumatic tool to stop quickly.
Setting direction of rotation
The pneumatic tool can rotate both clockwise and anticlockwise. Pressing the "butterfly" lever on either side will cause the
direction of rotation to be automatically selected (picture 3-b):
" R " REVERSE anticlockwise (unscrewing) – seen from the operator's side
" F " FORWARD
clockwise (screwing) – seen from the operator's side
The driving torque can be adjusted through the speed selector (picture 4).
- selection 1 minimum screwing/unscrewing torque (approximately 1/3 of max. torque)
- selection 2 medium screwing/unscrewing torque(approximately 2/3 of max. torque)
- selection 3 maximum screwing/unscrewing torque
Fit the required impact socket onto the male drive, and make sure that it is inserted correctly.
Always disconnect the air supply before fitting in tools or making adjustments; this precaution will prevent the
pneumatic tool from being accidentally started.
Lubrication/Greasing
The pneumatic tool must be connected to a filter-lubricator unit provided with an air-oil microfog mixer (we recommend Beta item
1919F1/4), 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 either the air
supply hole or the screw (pictures 5).
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.
