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
1/4" square drive (1) of the wrench.
1/4" extension bar
The 1/4" extension bar (7) can be used for confin-
ed spaces where there is limited space to operate
the wrench. To mount the 1/4" extension bar (7),
firmly press it onto the 1/4" square drive (1).
1/4" socket bits
The 1/4" socket bits (8) can be used for tightening
bolts, for example those of a bicycle part. To mount
the 1/4" socket bit (8), press it firmly onto the 1/4"
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 tor-
que 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 1/4" 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 16 Nm, as shown on Fig. E:
a. Turn the Handle (3) until top of handle lines
up with bottom horizontal mark for 15 and 0
lines up with centre line.
b. Turn Handle (3) until the 1.0 lines up with
the centre line.
c. The torque value is now set to 16 Nm (15 +
1 = 16).
7. Retighten the Lock Knob (4) by turning it
clockwise until it stops.
