DUAL FUNCTION TRIGGER SWITCH
To turn the tool "ON" in the Drilling/
Hammering mode, squeeze and hold the
trigger switch. To turn the tool "OFF",
release the trigger switch, which is spring
loaded and will return to the "OFF" position
automatically.
Your tool is also equipped with a "Lock-ON"
feature when the selector dial is in the
Hammering Only mode which allows
continuous operation without holding the
trigger.
TO LOCK TOOL "ON": turn the selector dial
to the Hammering Only mode and squeeze
the trigger switch until it locks.
TO TURN TOOL: "OFF" press the trigger
release switch and the trigger will return to
the "OFF" position automatically.
To increase switch life, do not turn switch on
and off while tool is under load.
VARIABLE SPEED DIAL
Your tool is equipped with a variable speed
dial. The impact rate (BPM) and rotating
speed (RPM) can be varied according to the
type of work being performed by setting the
variable speed dial to the selected setting.
The chart below will help you to determine

Operating Instructions
which setting to use for your application.
However, a pre-test will determine the best
speed setting, as the chart is intended only
as a guide. Once the proper setting is
determined the impact rate and rotating
speed is kept constant by means of the
"Electronic Feedback Circuitry". The variable
speed dial can be adjusted while the motor
is running, allowing the operator to adjust
the impact rate and rotating speed
according to the actual application.
In the "Hammer Only" mode power is
automatically increased 20% when the tool
is turned on to provide maximum chiselling
performance.
ELECTRONIC FEEDBACK CIRCUITRY
The internal electronic feedback system
provides a "soft start", which will reduce the
stresses that occur from a high torque start.
The system also helps to keep the pre-
selected impact rate and rotating speed
virtually constant between no-load and load
conditions.
Clean the insert shank end of the accessory
to remove any debris, then lightly grease
with a light oil or lubricant.

rotary hammers can only be obtained if
sharp and undamaged accessories are used.
The "cost" to maintain sharp and
