INSTRUCTIONS FOR USE
Torque setting adjustment:
Example: To set the torque to 50Nm.
1.
To unlock the handle turn the lock nut
(1)
anti-clockwise.
2.
Turn the knurled handle
(2)
until the zero marked on
the scale
(3)
is in line with the next lowest torque
setting on the Newton meter linear scale
(4)
. In this
case 40Nm.
3.
Continue to turn the knurled handle seven more
graduations (1 graduation on scale
(3)
equals
1Nm). The wrench is now set at 47Nm.
4.
Tighten the lock nut
(1)
to secure the setting.
Method of use:
IMPORTANT!
Always use the correct size socket and if necessary
an accessory. Preferably do not use knuckle or
universal joints, as these could result in incorrect
torque settings.
1.
Place the square drive onto the socket or extension
bar so that the wrench is perpendicular to the nut or
bolt that you wish to be tightened.
2.
Gripping the knurled handle
(2)
with the right hand,
whilst supporting the square drive end with the left
hand, gently but firmly apply a steady pull to the
handle (in a clockwise direction) until a click is
heard and a slight ‘break’ in the handle is felt.
Do not turn any further.

This torque wrench has a reversible
ratchet head (see fig. 2). Set the direction indicator
(5)
