Dear Customer,
You have purchased a high quality torque wrench
from the "PROXXON MicroClick" range. Now you
possess a robust precision instrument with high
release accuracy.
Please note; every instrument is only as good as
the user. Please read and carefully observe the fol-
lowing operating instructions.

Adjustment of the torque value
1. Slide the lock ring (5, Fig. 1) back at the end of
the handle and set the desired torque by tur-
ning the lock ring. Observe the torque value on
the analogue scale (3, resp. 6).
2. Slide the lock ring in front again. The required
torque value is locked now.
Please note:
The torque indicator is made up of two parts: The
top scale is used to pre-select the required torque
value, and the bottom scale is used for the fine
adjustment!
Due to the construction type, any occurring slight
deviations of the scale gradations of the top scale
at the end of the adjusting procedure cannot
always be avoided and do not in any way affect the
precision of your key while working.
The value set on the scale for fine adjustment is
definitive!
Working with the MicroClick
Caution! Before first use, and after a longer storage
period, operate the torque wrench a few times to
evenly lubricate the mechanics in the higher torque
range.
1. Adjust to the required torque.
2. Mount the required power socket on square-end 1

3. Pull the torque wrench through slowly and even-
ly. The adjusted torque is signalled by a noticea-
ble tug with a simultaneous clicking noise. The
higher the adjusted torque, the louder the signal.
4. The socket can be unlocked by pressing the
release button (Pos. 6, Fig. 1).
Not for MC 500: Here the socket can simply be
removed.
Important!
The torque function is switched off by repositioning
the locking lever (2, Fig. 1).
Do not operate the torque wrench with adapter for
other square drive sizes, but simply use socket
wrench inserts with the same square drive size as
intended.
The square drive of the wrench is adjusted to the
torque to be set with the mechanics of the torque
wrench. If when using an adapter and socket
wrench inserts of a correspondingly larger size, tor-
ques are generated for which the torque wrench is
not designed, the mechanics or the square drive
may be damaged. In this case, no warranty claims
may be made.
Caution:
Do not use the wrench for loosening extremely
tightened or corroded bolts and nuts!
Note
• Only actuate the torque wrench using the handle!
• Do not use an extension!
This would impair the set value being correctly
signalled.
• Handle your torque wrench as carefully as you
would treat a measuring instrument!
Maintenance and Inspection
• Set the torque to the lowest setting following
use to relieve stress on the compressive
spring!!!
• Never disassemble the torque wrench yourself!
For all repairs or malfunctions, please send the
wrench to our central service. The address is
printed on the last page of these instructions.
If it becomes necessary to calibrate the device,
please return to the manufacturer. You will find
the address on the back page of these instruc-
tions.
• Only clean the unit using dry materials - do not
dip it in petrol or solvent!
