3. OPERATING INSTRUCTIONS

WARNING!

Ensure Health & Safety, local authority, and general workshop practice regulations are adhered to when using this equipment.

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.

1. SAFETY INSTRUCTIONS

The AK629 Torque multiplier is robustly constructed with a 1/2” Sq. Drive Female input and a 3/4” Sq. Drive Male output. Multiplication of torque
is achieved by a planetary gear train with a ratio of 3.3:1. Compatible with a wide range of drive tools including torque and ratchet wrenches.
Adjustable length reaction arm make it ideal for limited access use. 

2. INTRODUCTION & SPECIFICATION

INSTRUCTIONS FOR:

TORQUE MULTIPLIER

Model No: 

AK629

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 1/2” female input socket and a 
suitable size socket fitted onto the male 3/4” 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.
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).
