1. How to install/tighten threaded fasteners.
Push the switch (D1) clockwise and have the
arrow on the switch (D1) pointing at either of
the three dots on the back housing as shown.
Press the trigger (C1). The tool anvil (B1) runs
clockwise.
(See Figure 25)
2. How to remove/loosen threaded fasteners.
Push the switch (D1) counterclockwise and
have thearrow on the switch (D1) pointing at
the large dot on the back housing as shown.
Press the trigger (C1). The tool anvil (B1) runs
counterclockwise.
(See Figure 26)
NOTE: This tool features a power
regulator valve. Turn the switch (D1)
slowly forward until desired output is
achieved. The three dots (small,
medium, large) do not denote a specific
power output but are only for reference.
"Setting 1" (small dot) is the least
amount of power, which is suitable for
just mounting threaded fasteners on
workpiece while "Setting 3" (large dot)
is the greatest amount of power, which
is for tightening threaded fasteners on
workpiece. This tool operates in
maximum power in reverse, which
releases threaded fasteners from
workpiece with ease. Choose the
correct torque needed on workpiece
when mounting or releasing threaded
fasteners by understanding the
reference torque listed below.
(See Figure 27)
NOTE: Make sure that this tool has the
correct torque to tighten/release
threaded fasteners. The torque applied
to threaded fasteners can be found in
their instructions or manuals.
