OPERA
TING INSTRUCTIONS
NOTICE:
• Mode selection requires that the lock button is in the ON position.
• The impact/normal mode setting won’t change after you turn off the tool or change the battery pack. Always check to make
sure that the tool is in the desired mode when you start the tool.
• Do not use the impact mode for long periods of continuous working, this can reduce the life of the impact ratchet.
• Do not over-tighten, as the force of the auto ratchet can break the fastener. Keep the socket at a right angle to the fastener
to avoid damaging the fastener head.
