KT Pneumatic Wrench

The design of New Twin Hammer structure is based on Twin Hammer structure. One of the severe issue of Twin Hammer is that the hammer cage is way too easy to break down due to its crowd space. The new design, New Twin Hammer, add on a partition in the middle of the hammer cage, which increase the resistance of the structure in order to reduce the possibility of breaking.

In the hammer cage, the pin of theTwin Hammer structure remains dangling in the center, which allows the pin to easily break after striking. Therefore, in the new design, the pin is assembled in a semicircle goove that can highly increase the stability of the whole combination.

1. Working: Push the bar to the R side to tighten the screws. On the contrary, the bar should be pushed to the L side when unscrewing the screws. Please note that this switching process cannot be done while pulling the trigger.

2. Adjusting: After using the pneumatic wrench, reverse the rotating direction and pull the trigger for approximately 1 second to finish a proper procedure of screwing. Then, the torque can be adjusted to meet the requirement by the adjustable button on the side.

3. General screws can be tightened in 2 to 3 seconds. If the screwing process last for 5 seconds, no matter tightening or unscrewing, means that the screw requires the pneumatic tools with higher torque.

1. Offering Oil: Please fill 2~3 cc pneumatic oil from the air inlet into the tool before and after daily use in order to approach the goal of cleaning, lubricating and anti-rusting while the oil is cycling in the interior motor components. After injecting the oil, run the tool in each direction for a few seconds, then the work can be continued after the excessive oil is discharged. The pneumatic oil should be filled several times in the middle of a long-term working session. Last but not least, to assure the pneumatic tool to function normally, reach the service life accurately, reduce the repairing cost and increase the working efficiency as far as possible, please fill `Pneumatic Oil` only!

2. Lift Room: Clean off the old lubrication grease from the lifting room of the pneumatic tool every 3 months, then apply new grease to replace the old. Please note that excessive lubrication grease can effect and decrease the ability of the tool. Nevertheless, it is noticeably that tools with oil way should be filled with a few lubrication grease from the filling hole every single month in order to increase the service time of the lifting room.

When it comes to repairing, pneumatic wrench is mostly divided into three main parts, which are the front cover, cylinder (the adjusting button) and air inlet.

The front cover part is divided into four components:
A-Spindle, B-Hammer cage, C-Hammer, D-Pins.

Several reasons of why the front cover should be repaired:

1. Why is my pneumatic tool consuming air yet the rotation is inconsistent or not even rotating?
   ANS: The component C, which is the Hammer, may be broken.

2. Why can`t I elevate the torque of my pneumatic wrench?
   ANS:There may be gaps while assembling or after the assembly.

A hex wrench will be enough when it comes to the maintenance of the front cover part of the pneumatic wrench.

New Twin Hammer replacing steps:

1. Stack two hammers in reverse direction.

2. Put into the hammer cage.

3. Place two Pins in.

4. Then try to rotate the spindle after installing it in. (Rotate back and forth to make sure it`s smooth enough.).

5. Then set the entire group of parts into the machine.

6. Screw the cover on with three screws. (Three screws should be tightened at the same time in order to avoid the damages of the screws.).

The air inlet is divided into two consumables, component A and B:
A-Buckle, B-Inlet valve.

Several reasons of why the air inlet should be repaired:

1. The rotation start automatically without pulling the trigger or the trigger isn`t rebounding after pulling it.
   ANS: There may be impurities attatched on the air inlet or the trigger is damaged.

2. The issue of air leaking?
   ANS: The buckle may be dented or jammed by impurities.

* Repairing air inlet requires special tools, hence the clients that wish to repair by yourselves can purchase the tools in order to increase the conveniency.
