PRECAUTIONS ON USING CORDLESS
AUTOMATIC SCREWDRIVER
1.
This automatic screwdriver is designed for tight-
ening and loosenig screws. Use it only for these
operation.
2.
Use the earplugs if using for a long time.
3.
One-hand operation is extremely dangerous; hold
the unit firmly with both hands when operating.
4.
Use original bits specifically for the automatic
screwdriver.
Use no bits other than the original bits specifically
for the automatic screwdriver. Use of any other
bit can result in screws sticking out and screw
feed malfunctioning.
5.
After installing the driver bit, pull lightly out the
bit to make sure that it does not come loose. If
the bit is not installed properly, it can come loose
during use, which can be dangerous.
6.
Screw in screws with the main unit held straight.
If the driver is slanted relative to the screw, the
screw head can be damaged and the bit worn.
Moreover, the prescribed torque is not transmit-
ted to the screw, resulting in screws left sticking
out. Place the drive straight against the screw and
screw in.
7.
Use the prescribed screws.
Do not use any other screws. They can cause
abnormal work (screws fallen over or sticking out)
and break downs (screw jamming and bit wear).
8.
Protect your eyes with protective glasses.
Always wear protective glasses while working.
Drilling scatters plaster powder and tape dust,
which are dangerous if they get into your eyes
9.
Watch out for wires and pipes in walls and ceilings.
When working on floors, walls, or ceilings, check
for wires and pipes ahead of time. Work carefully
to avoid shocks and explosions.
10.
When the screw feed attachment is removed,
always use the correct driver bit for the screw size.
11.
When the screw feed attachment is removed, if
the screwdriver is positioned at an angle against
the tightening screw, the head of the screw may
be damaged or the fixed tightening force will not
transfer to the screw. Always position the tight-
ening screw and the screwdriver at a straight
angle and then tighten the screw.
12.
Always charge the battery at a temperature of 5
– 40°C.
A temperature of less than 5°C will result in over
charging which is dangerous. The battery cannot
be charged at a temperature greater than 40°C.
The most suitable temperature for charging is that
of 20 – 25°C.
13.
Do not use the charger continuously.
When one charging is completed, leave the charger
for about 15 minutes before the next charging of
battery.
14.
Do not allow foreign matter to enter the hole for
connecting the rechargeable battery.
15.
Never disassemble the rechargeable battery and
charger.
16.
Never short-circuit the rechargeable battery.
Short-circuiting the battery will cause a great
electric current and overheat. It results in burn or
damage to the battery.
17.
Do not dispose of the battery in fire.
If the battery burnt, it may explode.
18.
Do not insert object into the air ventilation slots
of the charger.
Inserting metal objects or inflammables into the
charger air ventilation slots will result in electrical
shock hazard or damaged charger.
19.
Bring the battery to the shop from which it was
purchased as soon as the post-charging battery
life becomes too short for practical use. Do not
dispose of the exhausted battery.
20.
Using an exhausted battery will damage the
charger.
