WARNING:
release the switch trigger and remove the battery
cartridge from the tool. Failure to release the trig-
ger and removing the battery cartridge may cause a
personal injury.

sleeve before operation. Otherwise the tool may
lose control and result in personal injury.
To adjust the length of the shaft, turn the lock sleeve
counterclockwise until the arrow mark on the lock
sleeve indicates the unlock mark on the housing, and
pull out or push in the shaft to the desired length.
After adjustment, tighten the lock sleeve until the arrow
mark on the lock sleeve indicates the lock mark on the
housing.
