Tool use and care
Use clamps or another practical a.
way to secure and support the
ATV or Motorcycle on the platform.
Holding the work by hand or against

Disconnect the tool from the air d.
source before making any adjustments, changing accessories, or
storing the tool. Such preventive
safety measures reduce the risk of
starting the tool unintentionally. Turn
off and detach the air supply, safely
discharge any residual air pressure,
and release the throttle and/or turn
the switch to its off position before
leaving the work area.
Store the tool when it is idle out of e.
reach of children and other untrained persons. A tool is dangerous
in the hands of untrained users.
