FUNCTIONAL DESCRIPTION

CAUTION:
Always be sure that the tool is switched off and
•
unplugged before adjusting or checking function on
the tool.
Switch action
Fig.1
CAUTION:
Before plugging in the tool, always check to see
•
that the switch trigger actuates properly and returns
to the "OFF" position when released.
For 6904VH
To start the tool, simply pull the switch trigger. Tool speed
is increased by increasing pressure on the switch trigger.
Release the switch trigger to stop.
For 6905H
To start the tool, simply pull the switch trigger. Release
the switch trigger to stop.
Reversing switch action
Fig.2
For 6904VH
This tool has a reversing switch to change the rotational
direction. Press the upper side (FWD side) for clockwise
(forward) rotation or the lower side (REV side) for
counterclockwise (reverse) rotation.
For 6905H
This tool has a reversing switch to change the rotational
direction. Press the right side of the switch for clockwise
(forward) rotation or the left side for counterclockwise
(reverse) rotation.
Fig.3
CAUTION:
Always check the direction of rotation before
•

operation.

Use the reversing switch only after the tool comes
•
to a complete stop. Changing the direction of
rotation before the tool stops may damage the tool.
Speed change
Fig.4
For 6904VH only
To change the speed, first switch off the tool and then
slide the speed change lever fully to the "H" side (lower
side) for high speed or to the "L" side (upper side) for low
speed. Before starting operation, ensure that the speed
change lever is slid fully to the desired side. Select the
speed optimum for your job.
CAUTION:
Do not use the speed change lever while the tool is
•
running. The tool may be damaged.
ASSEMBLY
CAUTION:
Always be sure that the tool is switched off and
•
unplugged before carrying out any work on the tool.
Selecting correct socket
Always use the correct size socket for bolts and nuts. An
incorrect size socket will result in inaccurate and
inconsistent fastening torque and/or damage to the bolt
or nut.
Installing or removing socket
Fig.5
1. For socket without O-ring and pin
To install the socket, push it onto the anvil of the
tool until it locks into place.
To remove the socket, simply pull it off.
2. For socket with O-ring and pin
Fig.6
Move the O-ring out of the groove in the socket and
remove the pin from the socket. Fit the socket onto
the anvil of the tool so that the hole in the socket is
aligned with the hole in the anvil. Insert the pin
through the hole in the socket and anvil. Then
return the O-ring to the original position in the
socket groove to retain the pin. To remove the
socket, follow the installation procedures in
reverse.
OPERATION
The proper fastening torque may differ depending upon
the kind or size of the bolt, the material of the workpiece
to be fastened, etc. The relation between fastening
torque and fastening time is shown in the figures.
