3. ASSEMBLY
Mounting accessories (Fig. A, B, C)
Use only sockets with the correct drive and
rated to at least the torque that will be
applied to it.
Do not use accessories or socket extensi-
ons unless specifically required. The more
extensions used, the less accurate the
torque setting will be.
Avoid using universal joint extensions as
these will give an inaccurate torque reading.
Sockets and/or accessories can be mounted on the
1/2" square drive (1) of the wrench.
1/2" extension bar
The 1/2" extension bar (7) can be used for confin-
ed spaces where there is limited space to operate
the wrench. To mount the 1/2" extension bar (7),
firmly press it onto the 1/2" square drive (1).
1/2" to 3/8" adapter
The 1/2" to 3/8" adapter (8) can be used to mount
3/8" size accessories onto the 1/2" size drive of

the wrench. To mount the 1/2" to 3/8" adapter (8),
firmly press it onto the 1/2" square drive (1).
1/2" square drive sockets
The 1/2" extension sockets (9) can be used for
tightening bolts, for example those of a car alloy
wheel. To mount the 1/2" square drive socket (9),
press it firmly onto the 1/2" square drive (1).
4. OPERATION
Before first use (Fig. A)
Read the entire safety information section
at the beginning of this manual including all
text under subheadings therein before set
up or use of this product.
• Before each use, inspect the general condition
of the tool. Check for loose hardware, misalig-
nment or binding of moving parts, cracked or
broken parts, and any other condition that may
affect its safe operation.
• As most torque wrenches are length specific,
always grasp the torque wrench in the centre
of the handle (3). If two hands need to be used,
place one hand on top of the other.
• Before you start tightening the bolt with a
torque wrench, you need to know what torque
fits the bolt. This is usually stated in the manual
for car and motorcycle manufacturers. If not,
consult the manufacturer.
• Note that after 5000 cycles or up to one year of
use, whichever comes first, it is strongly advi-
sed to have your torque wrench inspected and
recalibrated by a reputable calibration service.
Using the torque wrench (Fig. A-E)
1. Wear PPE-approved safety goggles and he-
avy-duty work gloves.
2. Clean and/or repair the threads that will be
tightened. Damaged or dirty threads will result
in a misleading torque reading.
3. Select the desired socket and verify it fits
properly on the nut or bolt being tightened.
4. Press the socket firmly onto the 1/2" square
drive (1), as shown on Fig. C3.
5. Turn the Lock Knob (4) at bottom of the Handle
counter clockwise until it stops, as shown on
figure D.
6. Turn the handle (3) to set the torque. For exam-
ple to set to 76 Nm, as shown on Fig. E:
