Speed change
To change the speed, slide the speed change
lever to the
"H"
side for high speed or
"L"
side for low speed. To slide the speed
change lever easily, pull the trigger slightly
while pushing the speed change lever.
Be
sure that the speed change lever
is
set
to
the correct position before operation. Use
the right speed for your job.
CAUTIO N
:
Always
set
the speed change lever fully into the correct position. If you operate the tool
with the speed change lever positioned halfway between the
"H"
side and
"L"
side, the
tool may be damaged.
Adjusting fastening torque
The fastening torque can be adjusted in six
stages
by turning the adjusting ring
so
that
the pointer on the adjusting ring points to
a
number on the tool body. The fastening
torque
is
minimum when the pointer points
to the number
1
and maximum when
it
points to the
-\-
marking. The clutch will
slip
at
varying torque
levels
when the
pointer
is
set
at
the numbers
1
to
5.
The
clutch
is
designed not to slip
at
the
-8-
marking.
Before actual operation, drive
a
trial screw into your material or
a
piece of duplicate
material to determine which torque
level
is
required for
a
particular application.
NOTE
:
The adjusting ring cannot be locked with the pointer positioned half-way between the
numbers.
Screwdriving operation
Place
the point of the driver bit in the
screw head and apply pressure to the tool.
Start the tool slowly and then increase the
speed gradually.
Release
the trigger
as
soon
as
the clutch cuts in.
