The EY7443 offers AUTO mode,

which detects the load on the tool and

automatically switches between HIGH

and LOW speed operation.

When the load is low, the tool always

starts operation in HIGH speed.

When the tightening torque increases,

the tool switches to LOW speed. Keep

a secure grip on the tool so that it

doesn’t twist out of your hands due to

the increased torque.

When operating in AUTO mode,

whether and when the tool switches

between HIGH and LOW s p e ed

operation will depend on the specific

work conditions. These variations in

tool behavior are normal and do not

represent a malfunction.

When selecting AUTO on the

During AUTO mode operation, the tool

may switch to LOW speed under light

loads if there is little remaining battery

life or if the battery pack temperature is

low (0°C or less). In this case, charge the

battery pack or place the battery pack in

a warm location for at least one hour to

allow it to warm up before use.

Depending on the load, the tool may

switch back and forth between HIGH and

LOW speed operation multiple times. If

this switching is undesirable, set the tool

to HIGH or LOW speed manually.

Use at low speed when high torque

is needed during operation. (Using

at high speed when high torque

is requi r ed ma y cau se a m otor

Do not operate the speed selector

switch (LOW-HIGH) while pulling on

and a screwdriver bit locked in

place, the tool can be used as a

manual screwdriver (up to 22.6 N·m,

230 kgf-cm, 199 in-lbs).

There will be a little play in the chuck,

but this is not a malfunction.

2. This feature is handy for tightening

screws that require more torque than

the maximum torque of the driver

on the clutch), for conrming

the tightness of a screw or to loosen an

extremely tight screw.
