(c)Align the indentation in the hook main body with the protuberance of the hook cover, press the hook cover in the direction opposite to that of the arrow shown in Fig. 11 and then tighten the screw. Use commercially available AAAA batteries
(1.5 V).
NOTE:
Do not tighten the screw excessively. Such action could strip the screw threads.
CAUTION:
◯Failure to observe the following can result in battery leakage, rust or malfunction.
Position the plus (+) and minus
Remove exhausted batteries from the hook immediately.
◯Do not discard batteries together with normal trash and do not throw batteries into fire.
◯Store batteries out of the reach of children.
◯Use batteries correctly in accordance with the battery specifications and indications.
2.Check the rotational direction
The bit rotates clockwise (viewed from the rear side) by pushing the
The
counterclockwise. (See Fig. 13) (The L and R marks are provided on the body.)
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 screws
Install the bit that matches the screw, line up the bit in the grooves of the head of the screw, then tighten it.
Push the impact driver just enough to keep the bit
fitting the head of the screw.
CAUTION:
Applying the impact driver for too long tightens the screw too much and can break it.
Tightening a screw with the impact driver at an angle to that screw can damage the head of the screw and the proper force will not be transmitted to the screw. Tighten with this impact driver lined up straight wiÑ9 the screw.
5.Number of screws tightenings possible
Please refer to the table below for the number of screw tightened possible with one charge.
EB1430H
Screw used | No. of tightenings | |
Wood screw ø4 ⋅ 50 | Approx. 950 | |
(Soft wood) | ||
| ||
Machine screw M8 ⋅ 16 | Approx. 1890 | |
|
|
These values may vary slightly, according to surrounding temperature and battery characteristics.
NOTE:
The use of the battery EB1430H 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.
OPERATIONAL CAUTIONS
1.Resting the unit after continuous work
After use for continuous
battery. The temperature of the motor, switch, etc., will rise if the work is started again immediately after battery replacement, eventually resulting in burnout.
NOTE:
Do not touch the hammer case, as it gets very hot during continuous work.
2.Cautions on use of the speed control switch
This switch has a
3.Tightening torque
Refer to Fig. 18 the tightening torque of bolts (according to size), under the conditions shown in Fig. 19. Please use this example as a general reference,
as tightening torque will vary according to tightening conditions.
NOTE:
◯If a long striking time is used, screws will be strongly tightened. This may cause the screw to break, or may damage the tip of the bit.
◯If the unit is held at an angle to the screw being tightened, the head of the screw may be damaged, or the specified torque may not be transmitted to the
screw. Always keep the unit and the screw being tightened in a straight line.
4.Use a tightening time suitable for the screw
The appropriate torque for a screw differs according to the material and size of the screw, and the material being screwed etc., so please use a tightening time suitable for the screw. In particular, if a long tightening time is used in the case of screws smaller than M8, there is a danger of the screw breaking, so please confirm the tightening time and the tightening torque beforehand.
