1/2” DRIVE AIR IMPACT WRENCH
Impact Wrench User Instructions
7) Before Starting
TO PREVENT SERIOUS INJURY FROM EXPLOSION:
Verify compressor is off before setup. Use only clean, dry,
regulated, compressed air to power this tool. Do not use
oxygen, carbon dioxide, combustible gases, or any other
bottled gas as a power source for this tool.
1.
It is recommended a filter, regulator with pressure gauge, oiler,
in-line shutoff valve, and quick coupler be fitted for optimal
operation, as shown on Figure A.
2.
An in-line shutoff ball valve is an important safety device,
it will shut-off the air supply even if the air hose is ruptured.
The shutoff valve should be a ball valve because it can be
closed quickly.
Note:
If an automatic oiler system is not used, add a 4 to 5 drops of Kincrome Air Tool Oil to the air inlet before operation. Add 1 to
2 drops every hour for continual use.
3.
Attach an air hose to the compressor’s air outlet. Connect the air hose to the air inlet (5) of the tool. Other components, such as
a quick connect fitting and quick connect coupler, will make operation more efficient, but are not required.
WARNING!
Do not install a quick coupler directly on the tool. Couplers contains an air valve that will allow the air tool to
retain pressure and inadvertantly operate after the air supply is disconnected.
4.
The air hose must be long enough to reach the work area and allow free movement while working.
5.
Turn on the air compressor according to the manufacturer’s directions and allow the tank to build up pressure until it cuts-off.
6.
Adjust the air compressor’s regulator so that the air output is at the tools recommended working pressure, the output must not
exceed the tool’s maximum air pressure at any time. Adjust the pressure gradually, while checking the air output gauge to set
the optimal pressure range.
7.
Inspect all air connections for leaks.Repair any leaks.
8.
If the tool is not being used, turn off and detach the air supply, safely discharge any residual air pressure, and release the trigger
and/or turn the tools switch to its off position to prevent inadvertent operation.
8) Operation
1.
Screw in Nitto Style Fitting (6) to the air inlet (5). Thread (teflon) tape may be required to ensure a leak free seal.
2.
Connect the air hose to the air inlet (5) of the tool.
3.
Push and lock a 1/2” drive socket (not included) onto the Anvil (3). (Use only Impact Rated Kincrome Sockets)
4.
The Impact Wrench can be used in either Forward or Reverse direction by turning the forward/reverse switch (4) at the back of
the wrench.
Note:
There are 3 torque/speed settings for the Forward direction.
5.
For Reverse, turn the forward/reverse switch (4) to the right.
Note:
There is one torque setting for the Reverse direction.
6.
To tighten a nut or bolt, place the socket (not included) over the nut or bolt head of the bolt you wish to tighten.
7.
Hold the handle firmly and place other hand on top of tool. Then gently squeeze the trigger (2). When the nut or bolt is tightened
or loosened, release the trigger (2).
8.
To loosen, set the forward/reverse switch (4) to the Reverse setting.
9.
Place socket (not included) over desired nut or bolt head, hold the handle firmly and place other hand on top of tool. and gently
squeeze the trigger (2). When the nut or bolt is tightened or loosened, release the trigger (2).
10. If tool requires more power to accomplish task in forward or reverse, ensure that the tool is receiving sufficient, un-obstructed
airflow (CFM), increase/decrease the pressure (PSI) output of regulator ensuring you do not exceed the rated maximum inlet air
pressure of the tool.
Caution:
Do not exceed tool’s maximum inlet air pressure rating (90 PSI). If tool still does not have sufficient force at maximum
pressure and sufficient airflow, then a larger tool may be required.
