MAINTENANCE AND CARE
INTRODUCTION
K-DUCER and KDS screwdrivers are precision tools. While built to withstand heavy use in
industrial environments, good care and proper maintenance will go a long way in ensuring
the best performance and lifetime of your instrument.
Make sure to follow the INSTALLATION instructions for the K-DUCER, KDS screwdriver,
and the reaction arm.
The most important factor in ensuring long-lasting performance and lifetime of the
instrument is to configure it properly for the job required. Read this manual carefully to
ensure the tool is optimally configured for your application.
Some factors that can overwork and overheat the screwdriver include:
- Combination of high torque and low speed on very elastic joints (note that the
screwdriver delivers high torques more efficiently at higher speeds)
- Very high duty cycles (< 3 seconds between tightenings), depending on the difficulty
(torque, elasticity, speed) of the tightening
- High torques are defined as above 80% of the maximum nominal torque for the KDS
screwdriver model. Consider upsizing to a higher-torque screwdriver model if most
of your cycles are above 80% of the maximum nominal torque.
CALIBRATION
Recommended calibration interval: every 1,000,000 cycles. See TOOL INFO to check the
number of cycles of your KDS screwdriver.
Kolver supplies all KDS series screwdrivers with the transducer pre-calibrated on a semi-
elastic joint at a final speed of 100RPM (KDS models 15Nm and smaller) or 50RPM (KDS
models 20Nm and larger). The calibration settings are unique to each KDS screwdriver and
saved on the KDS screwdriver board.
Contact your Kolver representative to schedule a maintenance and calibration service with
Kolver or through one of our ISO/NIST certified lab partners.
Alternatively, Kolver can provide calibration instructions for you to perform the calibration
in-house.
MAINTENANCE
Recommended maintenance interval: every 500,000 cycles or 12 months, whichever comes
first. See
TOOL INFO to check the number of cycles of your KDS screwdriver.
