Operational Cautions - Metabo HPT WH 10DFL2 Instructions De Sécurité Et Mode D'emploi

CAUTION
Do not look directly into the light. Such actions
could result in eye injury.
9. Using the hook
The hook is used to hang up the power tool to your
waist belt while working.
If the hook is not attached to the unit, please attach it
by following the instructions below.
CAUTION
● When using the hook, hang up the power tool
fi rmly not to drop accidentally.
If the power tool is dropped, it may lead to an
accident.
● When carrying the power tool with hooked to
your waist belt, do not fi t any bit to the tip of
power tool. If the sharp bit such as drill is fi tted
to the power tool when carrying it with hooked to
your waist belt, you will be injured.
● Install securely the hook. Unless the hook is
securely installed, it may cause an injury while
using.
Attaching the hook and tightening the screws.
Install securely the hook in either left or right groove of
power tool and tighten the screws to fi x the hook with
philips screw driver fi rmly. (Fig. 8)

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.
CAUTION
Do not touch the metal parts, 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 diff ers 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 5/16" (8 mm), there
is a danger of the screw breaking, so please confi rm 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 diff ers 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 proportionate to
the operation time. Use the correct operating time for the
bolt.
5. Confi rm the tightening torque
The following factors contribute to a reduction of the
tightening torque. So confi rm the actual tightening torque
needed by screwing up some bolts before the job with
a hand torque wrench. Factors aff ecting the tightening
torque are as follows.
(1) Voltage
When the discharge margin is reached, voltage
decreases and tightening torque is lowered.
(2) Operating time
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 diff ers with the diameter of the
bolt. Generally a larger diameter bolt requires larger
tightening torque.
(4) Tightening conditions
The tightening torque diff ers according to the torque
ratio, class, and length of bolts even when bolts with
the same size threads are used. The tightening torque
also diff ers according to the condition of the surface of
workpiece through which the bolts are to be tightened.
When the bolt and nut turn together, torque is greatly
reduced.
