WARNING

Read operation manual completely 
before using torque instrument and  
store for future reference.

Wear safety goggles-both user and 
bystanders

• An out of calibration torque wrench  

can cause part or tool breakage

• Periodic re-calibration is necessary to 

maintain accuracy

• Do not exceed rated torque as 

overtorquing can cause wrench or part 
failure

• Do not use torque instrument to break 

fasteners loose

• Do not use cheater extension on the 

handle to apply torque

• Broken or slipping tools can cause 

injury.

CAUTION

 - RATCHET HEAD

Ratchet mechanism may slip or break 
if dirty, mismatched or worn parts are 
used, or direction lever is not fully 
engaged. Ratchets that slip or break  
can cause injury.

MAINTENANCE / sERvICE

1. The torque wrench’s internal mechanism is 

permanently lubricated during assembly. 

Do not 

attempt to lubricate the internal mechanism.

2. Clean torque wrench by wiping. 

Do not immerse.

3. Store torque wrench in protective tube at its lowest 

torque setting. 

Do not force handle below lowest 

setting.

ADJUsTMENTs OF 

TORQUE sETTINGs

1. Pull back on the lock lever to unlock the set knob. 

2. With the set knob turned to the lowest value, turn 

the knob clockwise to the desired value indicated at 
the set mark. If the value is exceeded, back off and 
approach the proper seting from the low side. 

3. Close the lock lever to lock the set knob at the 

torque setting. 

4. To torque fastener, keep hand centered on the 

handle, apply a slow steady force in the clockwise 
direction until a click/impulse is heard or felt. Stop 
pulling and allow the wrench to reset. 

UsE OF ExTENsIONs

AND ADAPTERs

When using an extension or adapter (increasing the 
effective length of the torque wrench) the output 
torque value will change. To calculate the new torque 
output of the wrench use the following formula:

TA = Torque exerted @ end of adapter
L = Distance between square drive and hand position
TW = Wrench scale reading
A = Length of adapter or extension

A number of variables can affect torque accuracy. 
These include the length of an adapter or extension, 
length of the wrench and variations in hand position 
on the wrench will affect the accuracy of the above 
calculation.
