 Never use the tool if the switch does not work. Any tool that cannot be controlled by the switch is dangerous and must be repaired before using it again.

 Always fit the tool with a fitting or hose coupling on or near the tool that all compressed air is discharged at the same time when the fitting or hose coupling is disconnected. Do not use a check valve or any other fitting that allows the air to remain within the tool. Death or serious personal injury might be the result.

 Never carry the tool by the air hose or pull the hose to move the tool away from a compressor.

Keep hoses away from heat, oil and sharp edges. Replace any hose that is damaged, weak or worn. Otherwise this might result in personal injury or damage to the tool.




Seite 20

 Do not drop or throw the tool. Dropping or throwing the tool can result in damage that will make the tool unusable or unsafe. If the tool has been dropped or thrown, examine the tool closely for bent, cracked or broken parts or any air leaks. If the tool has any damages, it must be repaired before being used again to avoid taking serious injuries.

 Clean and check all air supply hoses and fittings before connecting the tool to an air supply. Replace any damaged or worn hoses or fittings. This will reduce tool performance or its durability.

 Do not use the tool if it leaks air or does not function properly.

 Do not operate the tool if it does not contain a legible warning label.

TOOL SERVICE

 Use only accessories that are allowed by the manufacturer.

 When servicing a tool, only use original spare parts.

 Only use supplied lubricants specified by the manufacturer.

 Tool service must only be performed by the manufacturer or an authorized service partner.

OPERATION

 The amount of actual torque may vary depending on the cleanliness and condition of threads and other factors.



The warnings and precautions discussed in this manual cannot cover all possible conditions and situations that may occur. Always be aware and cautious while working with the tool.

 Only use it with accessories that are rated to handle the forces exerted by this tool during operation. Other accessories which are not designed for the generated forces may break and forcefully launch pieces.

 Attach all accessories properly to the tool before connecting the air supply. A loose accessory may detach or break during operation.

 Obey the manual for the air compressor used with this power tool.

 Install an in-line shutoff valve to allow immediate control over the air supply in an emergency, even if a hose is ruptured.

 Use this tool with both hands only. Using tools with only one hand can result in loss of control.

 Do not lay down the tool until it has come to a complete stop. Moving parts can grab the surface and pull the tool out of your control.

 Always handle the tool with care: o Respect the tool as a working implement.

o Never pull the trigger unless nose is directed toward the work.

o Keep others in a safe distance from the tool while the tool is in operation as accidental actuation may occur possibly causing injury.




Seite 21

AIR SUPPLY AND CONNECTIONS

 Do not use any type of reactive gases like oxygen carbon dioxide and combustible gases as a power source. Use filtered, lubricated, regulated compressed air only. Use of a reactive gas instead of compressed air may cause the tool to explode which will cause death or serious personal injury.

 Use only a pressure-regulated compressed air source to limit the air pressure supplied to the tool.

The regulated pressure must not exceed 90 PSI. If the regulator fails, the pressure must not exceed 90 PSI. The tool could explode which will cause death or serious personal injury.

 Always disconnect air source: o Before making adjustments o When servicing the tool o When tool is not in use o When moving to a different work area as accidental actuation may occur causing injury



Never connect the tool to an air source that may exceed 90 PSI. Over pressurizing the tool may result in bursting, abnormal operation, breakage of the tool as well as serious personal injury. Use only clean, dry, regulated compressed air at the rated pressure or within the rated pressure range as marked on the tool. Always verify prior to using the tool that the air source has been adjusted to the rated air pressure or within the rated air-pressure range.

FUNCTIONAL DESCRIPTION

Major components of 1/2” Air Impact Wrench: a) Anvil b) Control Valve c) Trigger d) Air Regulator e) Air Inlet

OPERATING PROCEDURES

SETUP AIR SOURCE

 The 1/2” air impact wrench is designed to operate on clean, dry, compressed air, regulated at 90

PSI. The preferred system would include a filter, a pressure regulator and an automatic oiler located as close to the tool as possible. Within 15 feet (4.5m) is ideal. Do not use bottled air or gases. Please see below (Fig.2):

 All compressed air contains moisture and other contaminants that can harm the internal components of the tool. An air filter will remove most of these and significantly extend the life of the tool. Ensure the in-line oiler has sufficient oil. If an inline oiler is not available, place 2 drops of oil into the tool’s air inlet at the beginning of each workday. More than this will be expelled from the tool’s exhaust during using (Fig.3).




Seite 23

 Air fitting: The 1/2” air impact wrench should be equipped with a 1/4” NPD male quick connector

(not included). To prevent accidental cycling even though disconnected, the tool must always be connected to the air supply in a ways that all air pressure within the tool is released when the coupling is disconnected.

CAUTION:

 All air pipe components (including hoses, pipe, connectors, filters, regulators etc.) must be rated for a working pressure of 90 psi.

 Disconnect the tool from the air supply before performing maintenance, leaving the work area, moving the tool to another location or handing it to another person.

PREPARING THE TOOL

Drain water from the air compressor tank and any condensation from air lines. (Please refer to the op eration manual of the air compressor)

 Lubricate the tool. (Please refer to the maintenance section in this manual)

 Select the necessary impact sockets. The sockets must match the size of the drive on the air impact wrench.

 Connect air impact wrench to the air source using the recommended hose size.

CAUTION:

 Keep tool pointed away from yourself and any other person at all times.

 Never use a tool that leaks air or needs repair.




Seite 24

OPERATING THE TOOL

1)

Remove plastic air inlet protective cap from air inlet as shown in Fig.4.

2)

Prepare a 1/4” male plug (not included) by applying sealant tape to the threading, wrapping clockwise. Screw threaded male air plug by hand into air inlet as shown in Fig.5 and tighten it with a wrench (not included) for an airtight connection. Note: Do not overtighten! Sealant tape must be used on this connection.

3)

Push the control valve forward so that the end of the valve protrudes out above the trigger for a clockwise (“forward”) tool operation.

4)

Push the control valve back so that the end of the valve protrudes from the back of the housing for counterclockwise (“reverse”) tool operation.

5)

Adjust the air flow by pushing down the air regulator and turning knob from positions 1 to 4 (Fig.2), aligning the desired number setting with the recessed arrow.

 Position 1 allows the lowest amount of air flow.

 Position 4 allows the highest amount of air flow.

6)

Push and snap the required 1/2” drive impact socket (not included) onto the anvil.

CAUTION:



Keep tool pointed in a safe direction at all times.



Only use impact rated accessories with this tool. Other accessories may shatter, chip or crack during operation.
