CHANGING SPEEDS
To change the speed of the chuck, push the
two-speed gearbox selection switch ✫✌,(fig.6
and 7) forwards for low speed, or backwards
for high speed.
IMPORTANT: ONLY CHANGE SPEED WHEN
THE MACHINE IS STOPPED.
TRIGGER
When the trigger is depressed the chuck will
rotate (provided the direction switch is set in
the forward or reverse position).This trigger
switch is electronic which enables the user to
vary the speed continuously in both gears.The
speed varies according to how far the trigger
switch is depressed, the further it is depressed
the faster the chuck will rotate and the lighter
it is depressed, the slower it will rotate.
TORQUE CONTROL
By turning the collar ✬✌, (fig.8) it is possible
to adjust the amount of torque.
In the “twist drill” setting , (fig.8), the drill
has full torque. In the “hammer” setting
the hammer action is engaged.
Settings 1-10 can be used in either gear and
provide a facility for setting the torque to the
required level. For example this means that
repetitive driving of screws of the same size
will be driven into the material to the same
torque, thus giving the same fixing strength, or
in the case of countersunk screws, these will all
be driven to the same depth in the material.
The torque control helps to prevent the heads
of small diameter screws being twisted off
when correctly set.
HOLDING THE DRILL
The drill casing is designed to be held
comfortably in two ways.
1. By the handle (fig.9).
2. Or, by the in-line support grip (fig.10).
