Setting the Electronic Speed and Impact Control Dial (Fig. 1, 3)
Turn the dial (G) to the desired level. Turn the dial upwards for higher speed and
downwards for lower speed. The required setting is a matter of experience. E.g.:
– when chiselling or drilling in soft, brittle materials or when minimum break-out is
required, set the dial to a low setting;
– when breaking or drilling in harder materials, set the dial to a high setting.
Setting the Torque Control Switch (Fig. 3)
NOTICE:
Always turn the tool off before changing torque control settings or
damage to the tool may result.
Move the torque control lever (T) to setting 40 Nm or 80 Nm as needed for
application.
Clutch Setting 40 Nm (U) is designed for most drilling applications and is
designed to easily clutch out when the drill bit encounters re-bar or other foreign
substances.
Clutch Setting 80 Nm (V) is designed for higher torque applications such as
core-bits and deep hole drilling and is designed to clutch out at a higher torque
threshold.
NOTE:
Allow the motor housing to rotate a little while changing torque.
Each time the tool is plugged in, it will automatically default to clutch setting 1 into
clutch setting 40 Nm (U), the most sensitive setting.
Indexing the Chisel Position (Fig. 5)
FIG. 5
F
The chisel can be indexed and locked into
18 different positions.
1. Rotate the mode selector switch (F) until
it points towards the position.
2. Rotate the chisel in the desired position.
3. Set the mode selector switch (F) to the
“hammering only” position.
4. Twist the chisel until it locks in position.
OPERATION
WARNING: To reduce the risk of serious
personal injury, turn tool off and disconnect
tool from power source before making
any adjustments or removing/installing
attachments or accessories.
WARNING: To reduce the risk of personal injury, ALWAYS ensure workpiece is
anchored or clamped firmly.
If drilling thin material, use a wood “back-up” block to
prevent damage to the material.
WARNING: To reduce the risk of personal injury, ALWAYS operate the tool with
the side handle properly installed and securely tightened.
Failure to do so may
result in the side handle slipping during tool operation and subsequent loss of control.
