VIbRATION HAzARD
This tool vibrates during use. Repeated or long-term exposure to vibra-
tion 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 medical or
physical 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.
4.
Wear suitable gloves to reduce the vibration effects on the user.
Use tools with the lowest vibration when there is a choice between dif-
ferent processes.

MAINTENANcE
1. If an in-line oiler is not used, disconnect the air hose and apply a few
drops of pneumatic tool oil through the air inlet coupling before each use.
Do this for every hour of continuous use.
2. Apply a few drops of oil to the Lever mechanism and work the Lever a
few times to lubricate.
Note: Do not use detergent, oil or additives; these will cause accelerated
wear to the tool’s air seals.
3. Wipe the Die Grinder clean of oil and grease with a clean cloth.
4. Do not allow the attachments to come in contact with oil or grease.
5. Replace the Die Grinder and attachments to the case and store in a
