NOTE:
• Use the proper bit for the head of the screw/bolt that you
wish to use.
• Hold the tool pointed straight at the screw or the screw
and/or bit may be damaged.
• When driving wood screws, predrill pilot holes to make
driving easier and to prevent splitting of the workpiece.
The pilot holes should be slightly smaller than the wood
screws in diameter.
• The size of wood screw which can be fastened with this
tool may differ depending upon the type of material to be
fastened. Always perform a test operation to determine
the size of wood screw.
• If the tool is operated continuously until the battery
cartridge has discharged, allow the tool to rest for 15
minutes before proceeding with a fresh battery.
CAUTION:
• Always be sure that the tool is switched off and the
battery cartridge is removed before attempting to
perform inspection or maintenance.
