Variable-Speed Trigger Switch
(Fig . 5)
Your tool is equipped with a variable-speed
trigger switch. The tool can be turned "ON" or
"OFF" by depressing or releasing the variable-
speed trigger switch.
The variable-speed trigger switch delivers
higher speed with increased trigger pressure
and lower speed with decreased trigger
pressure.
Auxiliary Handle (Fig . 6)
Secure the auxiliary handle onto the hammer
drill before working. To clamp the auxiliary
handle, rotate the handle clockwise. To loosen
the auxiliary handle, rotate the handle anti-
clockwise.
WARNING
operate the product without the auxiliary
handle to avoid accidents and injury!
Always ensure that the auxiliary handle is
attached and secured correctly before
operation! The auxiliary handle provides
better control of the tool in case of sudden
jams during use when considerable forces
are released!
Two-Speed Gearbox Switch (Fig . 7)
Your tool is equipped with a two-speed gearbox designed for operating at LO (1) or HI (2)
speeds. A slide switch is located on the top of the tool to select either LO (1) or HI (2) speed.
LO (1) speed provides higher torque and slower speeds for heavy-duty work or for driving
screws, drilling large diameters, or tapping threads. Use LO (1) speed for starting holes
without a center punch, drilling metals or plastic, drilling ceramics, or in applications requiring
a higher torque.
HI (2) speed provides lower torque and faster speeds for hammer drilling or lighter drilling
work. HI speed is better for drilling wood and wood composites and for using abrasive and
polishing accessories.
