WARNING
PRECAUTION AGAINST VIBRATION
AND COLD
IT IS BELIEVED THAT A CONDITION CALLED
RAYNAUD’S PHENOMENON WHICH AFFECTS
THE FINGERS OF CERTAIN INDIVIDUALS IS
BROUGHT ABOUT BY EXPOSURE TO COLD AND
VIBRATION.
ACCORDINGLY, YOUR ECHO TRIMMER HAS
SHOCK MOUNT AND RUBBERED GRIP.
DESIGNED TO REDUCE THE INTENSITY OF
VIBRATION TRANSMITTED THROUGH THE
HANDLES.
EXPOSURE TO COLD AND VIBRATION MAY
CAUSE TINGLING AND BURNING, FOLLOWED
BY LOSS OF COLOUR AND NUMBNESS IN A
PERSON’S FINGERS.
WE STRONGLY RECOMMEND YOU TAKE THE
FOLLOWING PRECAUTIONS BECAUSE THE
MINIMUM EXPOSURE WHICH MIGHT TRIGGER
THE AILMENT IS UNKNOWN.
• KEEP YOUR BODY WARM - ESPECIALLY
HEAD, NECK, FEET AND ANKLES, AND HANDS
AND WRISTS.
• MAINTAIN GOOD BLOOD CIRCULATION BY
PERFORMING VIGOROUS ARM EXERCISES
DURING FREQUENT WORK BREAKS, AND
ALSO BY NOT SMOKING.
• LIMIT THE NUMBER OF HOURS OF
OPERATION.
TRY TO FILL A PART OF EACH WORK DAY
WITH JOBS WHERE OPERATING THE TRIMMER
OR OTHER HAND-HELD POWER TOOLS IS NOT
REQUIRED.
• IF YOU EXPERIENCE DISCOMFORT,
REDNESS AND SWELLING OF THE
FINGERS, FOLLOWED WHITENING AND LOSS
OF FEELING, CONSULT YOUR PHYSICIAN
BEFORE EXPOSING YOURSELF FURTHER TO
COLD AND VIBRATION.
PROTECTIVE EQUIPMENT
• Always wear protection goggles that meet the national
standards.
• Wear hearing protection. If you use the unit for less
than two hours per day, we recommend that hearing
protection be worn at all times.
