Vibration Hazard
This tool vibrates during use. Repeated or long‑term exposure to vibration may cause temporary or permanent
physical injury, particularly to the hands, arms and shoulders. To reduce the risk of vibration‑related injury:
1. Anyone using vibrating tools regularly or for an
extended period should first be examined by a
doctor and then have regular medical check‑ups to
ensure medical problems are not being caused or
worsened from use. Pregnant women or people
who have impaired blood circulation to the hand,
past hand injuries, nervous system disorders,
diabetes, or Raynaud’s Disease should not use this
tool. If you feel any symptoms related to vibration
(such as tingling, numbness, and white or blue
fingers), seek medical advice as soon as possible.
2. Do not smoke during use. Nicotine reduces
the blood supply to the hands and fingers,
increasing the risk of vibration‑related injury.
3. Use tools with the lowest vibration when there
is a choice between different processes.
4. Include vibration‑free periods each day of work.
5. Grip tool as lightly as possible (while still keeping
safe control of it). Let the tool do the work.
6. To reduce vibration, maintain the tool as
explained in this manual. If any abnormal
