of parts, damaged or cracked hoses, bad connections and any other condition
that may affect the tool’s operation. If damaged, have the tool repaired
before use. Many accidents are caused by poorly maintained tools. Properly

Have your Planishing Hammer serviced by a qualied repair person using a.
only identical replacement parts. This will ensure that the safety of the tool is
maintained.
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:
Anyone using vibrating tools regularly or for an extended period should rst 1.
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 medical or physical symptoms related to vibration (such as
tingling, numbness, and white or blue ngers), seek medical advice as soon as
possible.
Do not smoke during use. Nicotine reduces the blood supply to the hands and 2.
ngers, increasing the risk of vibration-related injury.
Wear suitable gloves to reduce the vibration effects on the user.3.
Use tools with the lowest vibration when there is a choice between different 4.
processes.
Include vibration-free periods each day of work.5.
Grip the workpiece as lightly as possible (while still keeping safe control of it). 6.
Let the tool do the work.
To reduce vibration, maintain the tool as explained in this manual. If any 7.
abnormal vibration occurs, stop use immediately.
