TRIGGER "ON-OFF" SWITCH
To turn the tool "ON" squeeze the trigger
switch. To turn the tool "OFF", release the
trigger switch, which is spring loaded and
will
return
to
the
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
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 with the tool free from work,
allowing the operator to adjust the impact
rate and rotating speed according to the
actual application.
Chipping (Demolition)
Area of application
Plaster work
Removing tiles
Brick work
Concrete
Drilling Holes
Lower speeds
Larger holes
Accurate starts
Minimize breakouts
when the bit exits
the material.
ELECTRONIC FEEDBACK
CIRCUITRY (EFC)
The internal electronic feedback system
provides a "soft start", which will reduce the
stresses that occur from a high torque start.

Operating Instructions
The system also helps to keep the pre-
selected impact rate and rotating speed
virtually constant between no-load and load
conditions.
"OFF"
position
Clean the insert shank end of the accessory
to remove any debris, then lightly grease
with a light oil or lubricant.
Insert accessory into the tool holder through
the dust shield, while twisting and pushing
inward until it locks automatically into place.
Pull outward on the acessory to be certain it
is locked into the tool holder (fig. 2).
NOTE: You may notice some "wobble" or
"run out" of the bit when run in a no load
condition. This is due to the quick change
SDS tool holder assembly. However, once the
bit has a load placed upon it, the bit
automatically centers itself to produce an
accurate hole.
NOTE: The high efficiency available from the
rotary hammers can only be obtained if
sharp and undamaged accessories are used.
The "cost" to maintain sharp and
undamaged accessories is more than offset
by the "time saved" in operating the tool
with sharp accessories.
WARNING
!
Control setting
with skin and use proper protective gloves or
1 - 2
cloth to remove.
