item 1927P
Original documentation drawn up in ITALIAN.
Store the safety instructions with care and hand them over to the users.
P RPOSE OF SE
– The air compact impact wrench can be used for the following purposes:
• assembling threaded connecting parts
• screwing and unscrewing by means of impact sockets
• the angle impact wrench can also be used in open places exposed to water and air.
– The air compact impact wrench must not be used for the following operations:
• the angle impact wrench must not be used with any hand sockets
• the angle impact wrench must not be used with any couplers or extensions, because these result in reduced power of the impact
wrench and increased risk of breakage
• the angle impact wrench must not be used in environments containing potentially explosive atmospheres
• the trigger must not be locked with adhesive tape or clamps.
WORK AREA SAFETY
–Beware of both surfaces that may become slippery due to the use of the machine and the danger of tripping over the air hose.
–While using the pneumatic tool for jobs performed high from the ground, take all necessary precautions, to eliminate or minimize
risk to other workers, following the accidental falling of any tools (for example, isolation of the work area and proper signs).
Do not operate the pneumatic tool in environments containing potentially explosive atmospheres, because sparks may be
generated, which can ignite the dust or fumes.
Avoid contact with live equipment, because the pneumatic tool is not insulated, and contact with live parts can cause electric
shocks.
Keep children and bystanders away from your workplace while operating the pneumatic tool. Distractions from other people can
cause you to lose control over the pneumatic tool.
PNE MATIC TOOL SAFETY
–Do not point the air flow to yourself or other people. Compressed air can cause serious injury.
–Check the connections and the air supply lines. All units, couplers and hoses should conform to the product specifications in terms
of pressure and air volume. Too low pressure impairs the function of the pneumatic tool; too high pressure can cause damage
and/or injury.
–Do not bend or tighten any hoses. Avoid using solvents and sharp edges. Keep the hoses away from heat, oil and rotating parts.
Immediately replace any damaged hose. A defective feed pipe may cause uncontrolled movements of the compressed air pipe.
Raised rust or chips may cause eye injury. Make sure that the hose clamps are always secured firmly.
PERSONNEL SAFETY
–Stay alert; watch what you are doing. Do not use the pneumatic tool while tired or under the influence of drugs, alcohol, or
medication.
–Always use the following personal protective equipment:
• eye protection;
• safety shoes;
• gearing protection;
• protective gloves against physical agents;
• anti-vibration gloves, to be worn following a specially conducted survey of the daily exposure of the hand-arm system to vibration.
–Make sure you are in a safe position, keeping proper balance at all times. A safe working position and a proper body posture
enable better control of the pneumatic tool in unexpected situations.
–Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothing, jewellery, and
long hair can get caught in moving parts.
–Do not directly inhale the exhaust air, and prevent it from getting into your eyes. The exhaust air of the pneumatic tool can contain
water, oil, metal particles and impurities, which may cause hazards.

AIR IMPACT WRENCH SE AND CARE
–Use clamping devices or a vice to secure and support the workpiece. olding the workpiece by hand or against your body will not
allow for safe operation of the pneumatic tool.
–Do not overload the pneumatic tool. Use the pneumatic tool intended for your work only.
–Always check that the machine is free from defects. Do not use a pneumatic tool that has a defective On/Off switch. A pneumatic
tool that can no longer be stopped or started is dangerous and must be repaired.
–Make any adjustments while the air angle impact wrench is not working. Always disconnect the air supply when not in use. This
safety measure prevents accidental starting of the pneumatic tool.
–Store idle pneumatic tools out of the reach of children. Do not allow persons unfamiliar with these instructions to operate the
pneumatic tool.
–Maintain the pneumatic tool with care. Check for misalignment or binding of moving parts, breakage of parts and any other
condition that may affect the operation of the pneumatic tool. ave damaged parts repaired before using the pneumatic tool.
–Always use impact sockets in good condition.
–Do not modify the pneumatic tool. This can reduce the effectiveness of safety measures and increase operator risk.
–ave the pneumatic tool repaired only through a qualified repair person and only using original replacement parts.
AIR IMPACT WRENCH SAFETY
–Make sure that the nameplate is readable; get a replacement nameplate from the manufacturer, if need be.
–While the impact wrench is being used, any accidental breakages of individual accessories may cause pieces to be thrown at high
speed.
–Operators and maintenance personnel should be physically able to handle the weight and power of the pneumatic tool.
–It is important to be prepared for unexpected movements of the air impact wrench resulting from a jammed or broken work tool.
Maintain a firm grip on the pneumatic tool and position your body and arms to allow you to resist such movements. These
precautions can prevent injuries.
–Avoid contact with any moving parts of the tool, since these can cause injuries.
–Make sure that the direction of rotation of the air impact wrench is fit for use.
–Turn off the tool in case of air supply failure or low operating pressure. Check the operating pressure; turn on the tool again when
optimal operating pressure is resumed.
–When using the pneumatic tool, the operator can experience discomfort in the hands, arms, shoulders, or neck area. Adopt a
comfortable position and avoid awkward postures. Changing one’s posture may help avoid discomfort and fatigue.
Caution: If the pneumatic tool is used over a protracted period of time, part of the tool and the socket may become hot. Wear
protective gloves.
Using the pneumatic tool on the workpiece generates noise, which may prove harmful to the exposed personnel. A proper
phonometric survey is required to determine the personal hearing protective equipment (hearing protection) to use.
If a specially conducted survey suggests that the daily exposure to vibration generated from the pneumatic tool exceeds the limit
value under the regulations in force in the respective country, anti-vibration gloves must be worn.
–If you notice that the skin of your fingers becomes numb, turns white, tingles or hurts, stop working with the pneumatic tool, inform
your employer and seek medical advice.
–old the pneumatic tool with a not too firm yet secure grip, compliant with the required hand reaction forces.
–Never carry the pneumatic tool by the hose.

SE
Start / Stop
To start the pneumatic tool, press the start button (picture 3-b), and keep it pressed during the job to be performed. Releasing the
button will cause the pneumatic tool to stop quickly.
Check the position of the reverse lever (picture 4-d) 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-e):
clockwise – seen from the operator’s side
anticlockwise - seen from the operator’s side
Use the reverse lever to select the direction of rotation and couple:
selection •minimum screwing torque (approximately 1/3 of max. screwing torque)
selection ••medium screwing torque (approximately 2/3 of max. screwing torque)
selection •••maximum screwing torque
selection •maximum 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 (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 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.
