Characteristics of Cordless Oil-
impulse Driver
The Makita Cordless Oil-impulse Driver is a hydrauli-
cally operated impact tool using oil viscosity to produce
impacts. Since oil viscosity changes with the tempera-
ture, be aware of the following two points when operat-
ing the tool.
1. Avoid using the tool below -10 ºC (14 ºF) of tem-
perature. When the tool temperature goes down
below the degrees, this may cause damage to the
motor of tool due to poor impulse.
2. When the tool becomes too hot, it may take longer
to set screws.
3. The tool can overheat, causing a failure or hand
burn if you operate it continuously for long hours.
Let the tool cool off for more than 30 minutes
before changing batteries during a long, continu-
ous job.
Impact force grade

T mode
The impact force can be changed in four steps: hard,
medium, soft, and T mode.
This allows a tightening suitable to the work.
Every time the button
blows changes in four steps.
For approximately one minute after releasing the switch
trigger, the impact force can be changed.

Application
"T" is a special mode for fastening self drilling screws
and bolts. In this mode, the tool starts to drive a screw
with faster rotation, which is suited for drilling with the
self-drilling -screw tip. Once the tool starts to tighten the
screw, it impacts in soft force grade.
