Operational Cautions - Tyco Electronics IT-1000-023 Instrucciones De Manejo

(b) Remove the hook A and spring B (Fig. 6).
(c) Install the hook A and spring B on the other side
and securely fasten with screw (Fig. 7).
NOTE
Pay attention to the spring B orientation. Install the
spring B with larger diameter C away from you
(Fig. 7).
(3) Using as an auxiliary light
(a) Press the switch D to turn off the light.
If forgotten, the light will turn off automatically
after 15 minutes.
(b) The direction of the light can be adjusted within
the range of hook positions 1 – 5 (Fig. 8).
Lighting time
AAAA manganese batteries: approx. 15 hrs.
AAAA alkali batteries: approx. 30 hrs.
CAUTION
Do not look directly into the light.
Such actions could result in eye injury.
(4) Replacing the batteries
(a) Loosen the hook screw F with a phillips-head
screwdriver (No. 1) E (Fig. 9).
Remove the hook cover H by pushing in the
direction of the arrow (Fig. 10).
(b) Remove the old batteries and insert the new
batteries. Align with the hook indications and
position the plus (+) and minus (–) terminals
correctly (Fig. 11).
(c) Align the indentation in the hook A main body
with the protuberance of the hook cover H, press
the hook cover H in the direction opposite to that
of the arrow G shown in Fig. 10 and then tighten
the screw.
Use commercially available AAAA batteries
(1.5 V) K.
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 (–) terminals correctly.
Replace both batteries at the same time. Do not mix
old and new batteries.
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 R-side of the push button 0.
The L-side of the push button is pushed to turn the bit
counterclockwise (See Fig. 3) (The
are provided on the body).
CAUTION
The push button cannot 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.

OPERATIONAL CAUTIONS

1. Resting the unit after continuous work
After use for continuous bolt-tightening work, rest
the unit for 15 minutes or so when replacing the
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 protector, as it gets very hot during
continuous work.
2. Cautions on use of the speed control switch
This switch has a built-in, electronic circuit which
steplessly varies the rotation speed. Consequently,
when the switch trigger is pulled only slightly (low
speed rotation) and the motor is stopped while
continuously driving in screws, the components of the
electronic circuit parts may overheat and be damaged.
3. 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.
4. Work at a tightening torque suitable for the bolt
under impact
The optimum tightening torque for nuts or bolts differs
with material and size of the nuts or bolts. An
excessively large tightening torque for a small bolt
may stretch or break the bolt. The tightening torque
increases in proportion to the operation time. Use
the correct operating time for the bolt.
5. Holding the tool
Hold the impact wrench firmly with both hands. In
this case hold the wrench in line with the bolt.
It is not necessary to push the wrench very hard.
Hold the wrench with a force just sufficient to
counteract the impact force.
6. Confirm the tightening torque
The following factors contribute to a reduction of the
tightening torque. So confirm the actual tightening
torque needed by screwing up some bolts before the
job with a hand torque wrench. Factors affecting the
tightening torque are as follows.
(1) Voltage
When the discharge margin is reached, voltage
decreases and tightening torque is lowered.
(2) Operating time
R
L
and marks
The tightening torque increases when the operating
time increases. But the tightening torque does not
increase above a certain value even if the tool is
driven for a long time.
(3) Diameter of bolt
The tightening torque differs with the diameter of the
bolt. Generally a larger diameter bolt requires larger
tightening torque.
