without pressing the lock-off lever. Return the tool
to our authorized service center for proper repairs
BEFORE further usage.
WARNING:

tridge into the tool, always check to see that the
switch trigger actuates properly and returns to

NOTICE:
Do not pull the switch trigger hard with-

To prevent the switch trigger from being accidentally
pulled, a double lock-off switch is provided for safety.
To start the tool, push the lock lever down forward past
its normal position using the web of your hand (i.e., the
part between thumb and index finger) and squeeze
the lock-off lever with your palm. Then pull the switch
trigger with the lock-off lever being held. Tool speed is
increased by increasing pressure on the switch trigger.
