 WaRninG! do not use the tool if damaged or thought to be faulty (Contact Service Agent).
 Ensure the work area is clean and tidy and free from unrelated materials and there is adequate lighting.
 do not exceed the rated capacity of the torque multiplier.
 do not use the torque multiplier for any purpose other than that for which it is designed.
 do not operate the torque multiplier when you are tired or under the influence of alcohol, drugs or intoxicating medication.
 The torque multiplier is a precision tool, do not abuse it.
 Maintain correct balance and footing. Ensure the floor is not slippery and wear non-slip shoes.
 Keep children and unauthorised persons away from the working area.
 do not drop or throw the torque multiplier.
 do not use the torque multiplier unless you have been instructed in its use by a qualified person.
 do not use the torque multiplier with air or electric impact guns.
 After use clean and store in a safe, dry, childproof location.
2. intRoduction & sPecification
The AK629 Torque multiplier is robustly constructed with a ½" Sq. Drive Female input and a ¾" Sq. Drive Male output. Multiplication of torque
is achieved by a planetary gear train with a ratio of 1:3.3. Compatible with a wide range of drive tools including torque and ratchet wrenches.
Adjustable length reaction arm makes it ideal for limited access use.

3. oPeRatinG instRuctions
Please refer to the makers instructions for correct use and setting of the torque wrench.
3.1. The AK629 is used in combination with a suitable drive tool, such as a ratchet wrench or torque wrench fitted into the ½" female input socket and a
suitable size socket fitted onto the male ¾" drive square (fig.1).
3.2. If using a torque wrench, calculate the required input figure for the torque wrench by dividing the torque setting for the fixing by
a factor of 3.3 or refer to the quick conversion chart overleaf.
3.3. This assembly (fig.2) is now placed on the nut or bolt to be tightened with the reaction arm if possible restrained against some
substantial part of the equipment being serviced. Any force applied to the input drive is multiplied by a factor of 3.3 at the output drive
of the multiplier.
Note: Because the multiplier uses a system of gears, the output drive turns substantially slower than the input drive (3.3 turns of the drive
tool = 1 output turn to nut/bolt). When the preset torque setting is reached, the torque wrench mechanism will 'click'. Stop applying
force immediately to avoid overtightening the nut/bolt.
3.4. If required, the radius arm can be extended or retracted, use a small screwdriver or similar to push in the locking pin whilst twisting the
radius arm and simply manoeuvre the arm until the pin relocates as required (fig.3).
