Care And Maintenance - Michelin MTW-210 Mode D'emploi

CARE AND MAINTENANCE

1. The torque wrench is a precision instrument,
and should be stored with care. Don't throw it
around, use a hammer with it, or use it as lever
bar.
2. The torque wrench is lubricated for life and
should not be oiled. The only exception is the
ratchet head which may be lubricated as
needed for smooth operation.
3. The torque wrench is a precision measuring
instrument. Calibration must be done regularly
to ensure accuracy and it is the owner's
responsibility. Suggested calibration period is
at least every 12 months or even shorter
depending on situation.
4. Always store the torque wrench in the box after
use to keep it protected from dirt and humidity.
5. Never disassemble the torque wrench by
yourself. If the torque wrench needs to be
disassembled for repair, please seek assistance
from a qualified tool servicing agent. Any
incorrect action while disassembling the torque
wrench may result in permanent damage and
render the torque wrench unsafe for use.
EXTENSIONS & 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:
B=
A = Torque exerted @ end of adapter
L = Distance between square drive and hand
position
B = Wrench scale reading
C = Length of adapter or extension
A number of variables including the length of the
adapter or extension, length of the wrench and
variations in hand position on the wrench will
affect the accuracy of the above calculation.
A X L
L + C
