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

A. To unlock handle hold tube and pull lock ring back

allowing handle to turn CW or CCW.

B. Set wrench to desired torque as follows:
EXAMPLE - 64 ft. Ibs.

1. Keep slight rearward pull on lock-ring during all

adjustments.

2. Line up thimble edge with the “60” graduation

cross line and zero with vertical line. Wrench is
now set at 60 ft. Ibs. (See Figure I)

3. Turn handle and set thimble graduation to “4”

on vertical line. Wrench is now set at 64 ft. lbs.
(See Figure II)

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.

TW =

TA x L

L + A

4. Lock handle by releasing back pressure on lock·ring

until it clicks and handle doesn’t turn.

5. To torque fastener, keep hand centered on the grip

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