which may be generated in the use of certain hand–held tools
may produce Raynaud’s phenomenon, commonly referred to as
Whitefinger disease. The phenomenon produces numbness and
burning sensations in the hand and may cause circulation and
nerve damage as well as tissue necrosis. Repetitive users of
hand–held tools who experience vibrations should closely moni-
tor duration of use and their physical condition.

Lack of or an excessive amount of lubrication will affect the perfor-
mance and life of this tool. Use only recommended lubricants at
below time intervals:
EVERY 8 HOURS OF TOOL OPERATION – Fill lubricator reser-
