Erbauer ERI603COM - Operating Instructions: Speed and Direction; Variable Speed Operation; Forward and Reverse Rotation; Two-Speed Gear Selection

It is also a variable speed switch that delivers higher
speed and torque with increased trigger pressure.
Speed is controlled by the amount of switch trigger
depression.

WARNING: Do not operate for long
periods at low speed because excess
heat will be produced internally.
3. SWITCH LOCK
The switch trigger can be locked in the OFF position.
This helps to reduce the possibility of accidental
starting when not in use. To lock the switch trigger,
place the rotation control in the center position.
4. REVERSIBLE (See Fig. 4-1&4-2)
For drilling and screw driving use forward rotation
marked “ ” (lever is moved to the left). Only use
reverse rotation marked “ ” (lever is moved to the
right) to remove screws or release a jammed drill bit.

WARNING: Never change the direction of
rotation when the chuck is rotating, wait
until it has stopped!
5. TWO-SPEED GEAR CONTROL (See Fig. 5)
The drill has a two-speed gear control designed for
drilling or driving at LO (mark is 1) or HI (mark is 2)
speeds. A slide switch is located on top of the drill
to select either LO or HI speed. When using the drill
in the LO speed range, the speed will decrease and
the drill will have greater power and torque. When
using the drill in the HI speed range, the speed
will increase and the drill will have less power and
torque.
Gear I
Low speed range: for screwdriving or working with
large drilling diameter
Gear II
High speed range: for working with small drilling
diameter

WARNING: To prevent gear damage,
always allow the chuck to come to a
complete stop before changing the direction of
rotation or the two-speed gear control.
