INSTRUCTIONS FOR INSTALLING DEVICES
Side handle installation
Assemble the auxiliary handle (picture 3-c) by screwing it onto the front body of the air impact wrench (manually tighten the four
screws supplied with the impact wrench by means of the hexagon driver). The auxiliary handle can only be mounted on the left
side of the impact wrench body. Using the auxiliary handle results in increased ease of handling and firmness.
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 start lever (picture 2-b), and keep it pressed during the job to be performed. Releasing
the trigger will cause the pneumatic tool to stop quickly.
Check the position of the reverse lever before operating the pneumatic tool, so as to know the direction of rotation.
Setting direction of rotation
The pneumatic tool can rotate both clockwise and anticlockwise. Select the direction of rotation through the reverse lever (picture
4-d) in the lower part of the handle. Four different power levels can be selected, through selection 1-2-3-4 (picture 4-e).
“ L ” LEFT clockwise – seen from the operator’s side
“ R ” RIGHT anticlockwise – seen from the operator’s side
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
1919F1/2), 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 4-f, 5-f).
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.
