malfunctioning and degraded efficiency, replace
the drill bit with a new one or resharpening
without delay when abrasion is noted.
2. Inspecting the mounting screws.
Regularly inspect all mounting screws and
ensure that they are properly tightened. Should
any of the screws be loose, retighten them
immediately. Failure to do so could result in
serious hazard.
3. Maintenance of the motor.
The motor unit winding is the very “heart” of
the power tool. Exercise due care to ensure the
winding does not become damaged and/or wet
with oil or water.
4. Inspecting the carbon brushes.
The motor is equipped with carbon brushes,
which wear with time. When a brush reaches
the wear limit, the motor may malfunction.
If the engine is equipped with a disengaging
brush, it will automatically turn off. In this case
replace both carbon brushes. Keep the brushes
clean and ensure that brushes move freely
within the brush holders.

In case power cord of the tool is damaged,
contact ZENIT authorized service center to
replace it.
