2.Checking the battery
Make sure that the battery is installed firmly. If it is at all loose it could come off and cause an accident.
3.Selecting the socket matched to the bolt
Be sure to use a socket which is matched to the bolt to be tightened. Using an improper socket will not only result in insufficient tightening but also in damage to the socket or nut.
A worn or deformed hex. or
Pay attention to wear of socket hole, and replace before further wear has developed.
Finally, install the socket prescribed in Item 4. The section on “Optional Accessories” details the relationship between bolt sizes and sockets. Sockets are named according to the dihedral width of the hexagonal hole.
4.Installing a socket
Select the socket to be used.
⬤Pin,
(1)Align the hole in the socket with the hole in the anvil and insert the anvil into the socket.
(2)Insert the pin into the socket.
(3)Attach the ring to the groove on the socket.
⬤Plunger type (Fig. 6)
Align the plunger located in the square part of the anvil with the hole in the hex. socket. Then push the plunger, and mount the hex. socket on the anvil. Check that the plunger is fully engaged in the hole. When removing the socket, reverse the sequence.
HOW TO USE
1.Using the convenient hook
The convenient hook can be installed on the right or left side and the angle can be adjusted in 5 steps
between 0° and 80° .
(1)Operating the hook
(a)Pull out the hook toward you in the direction of arrow (A) and turn in the direction of arrow
(B). (Fig. 7)
(b)The angle can be adjusted in 5 steps (0°, 20°, 40°, 60°, 80°).
Adjust the angle of the hook to the desired position for use.
(2)Switching the hook position
CAUTION:
Incomplete installation of the hook may result in bodily injury when used.
(a)Securely hold the main unit and remove the screw using a slotted head screwdriver or a coin. (Fig. 8)
(b)Remove the hook and spring. (Fig. 9)
(c)Install the hook and spring on the other side and securely fasten with screw. (Fig. 8)
NOTE:
Pay attention to the spring orientation. Install the spring with larger diameter away from you. (Fig. 10)
2.Check the rotational direction
The bit rotates clockwise (viewed from the rear side) by pushing the
The
CAUTION
The push button can not be switched while the impact driver is turning. To switch the push button, stop the impact driver, then set the push button.
3. Switch operation
◯When the trigger switch is depressed, the tool rotates. When the trigger is released, the tool stops.
◯The rotational speed can be controlled by varying
the amount that the trigger switch is pulled. Speed is low when the trigger switch is pulled slightly and increases as the trigger switch is pulled more.
4.Tightening and loosening bolts
A hex socket matching the bolt or nut must first be selected. Then mount the socket on the anvil, and grip the nut to be tightened with the hex socket. Holding the wrench in line with the bolt, press the power switch to impact the nut for several seconds. If the nut is only loosely fitted to the bolt, the bolt may turn wit the nut, therefore mistaking proper tightening. In this case, stop impact on the nut and hold the bolt head with a wrench before restarting impact, or manually tighten the bolt and nut to prevent them slipping.
5.Number of bolt tightened possible
Please refer to the table below for the number of bolt tightened possible with one charge.
For WR12DM (EB1230HL)
Bolt used | No. of tightenings | ||
M16 ⋅ | 55 (F10T) | Approx. 135 | |
For WR9DM (EB930H) |
| ||
Bolt used | No. of tightenings | ||
High | tension bolt | Approx. 135 | |
M12 ⋅ 45 | |||
|
These values may vary slightly, according to surrounding temperature and battery characteristics.
NOTE
The use of the battery EB1230HL and EB930H in a cold condition (below 0 degree Centigrade) can sometimes result in the weakened tightening torque and reduced amount of work. This, however, is a temporary phenomenon, and returns to normal when the battery warms up.
