Important; Maintenance And Inspection - HIKOKI DM 20V Mode D'emploi

2. Drilling
○ When drilling, start the drill slowly, and gradually
increasing speed as you drill.
○ Always apply pressure in a straight line with the bit. Use
enough pressure to keep drilling, but do not push hard
enough to stall the motor or defl ect the bit.
○ To minimize stalling or breaking through the material,
reduce pressure on drill and ease the bit through the last
part of the hole.
○ If the drill stalls, release the trigger immediately, remove
the bit from the work and start again. Do not click the
trigger on and off in an attempt to start a stalled drill. This
can damage the drill.
○ The larger the drill bit diameter, the larger the reactive
force on your arm.
Be careful not to lose control of the drill because of this
reactive force.
To maintain fi rm control, establish a good foothold, use
side handle, hold the drill tightly with both hands, and
ensure that the drill is vertical to the material being drilled.

MAINTENANCE AND INSPECTION

1. Inspecting the drill bits
Since use of an abraded drill bits will cause motor
malfunctioning and degraded effi ciency, replace the drill
bits with a new one or resharpening without delay when
abrasion is noted.
2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure that
they are properly tightened. Should any of the screws be
loose, retighten them immediately. Failure to do so could
result in serious hazard.
3. Maintenance of the motor
The motor unit winding is the very "heart" of the power
tool. Exercise due care to ensure the winding does not
become damaged and/or wet with oil or water.
4. Inspecting the carbon brushes
For your continued safety and electrical shock protection,
carbon brush inspection and replacement on this tool
should ONLY be performed by a HiKOKI Authorized
Service Center.
5. Replacing supply cord
If the supply cord of Tool is damaged, the Tool must be
returned to HiKOKI Authorized Service Center for the
cord to be replaced.
CAUTION
In the operation and maintenance of power tools, the safety
regulations and standards prescribed in each country must
be observed.
GUARANTEE
We guarantee HiKOKI Power Tools in accordance with
statutory/country specifi c regulation. This guarantee does
not cover defects or damage due to misuse, abuse, or normal
wear and tear. In case of complaint, please send the Power
Tool, undismantled, with the GUARANTEE CERTIFICATE
found at the end of this Handling instruction, to a HiKOKI
Authorized Service Center.
NOTE
Due to HiKOKI's continuing program of research and
development, the specifi cations herein are subject to change

IMPORTANT

Correct connection of the plug
The wires of the mains lead are coloured in accordance
with the following code:
Blue: — Neutral
Brown: — Live
As the colours of the wires in the mains lead of this tool may
not correspond with the coloured markings identifying the
terminals in your plug proceed as follows:
The wire coloured blue must be connected to the terminal
marked with the letter N or coloured black.
The wire coloured brown must be connected to the terminal
marked with the letter L or coloured red.
Neither core must be connected to the earth terminal.
NOTE
This requirement is provided according to BRITISH
STANDARD 2769: 1984.
Therefore, the letter code and colour code may not be
applicable to other markets except the United Kingdom.
Information concerning airborne noise and vibration
The measured values were determined according to
EN62841 and declared in accordance with ISO 4871.
Measured A-weighted sound power level: 107 dB (A).
Measured A-weighted sound pressure level: 96 dB (A).
Uncertainty KpA: 3 dB (A).
Wear hearing protection.
Vibration total values (triax vector sum) determined
according to EN62841.
Impact drilling into concrete:
a
Vibration emission value
Uncertainty K = 2.1 m/s 2
Drilling into metal:
a
Vibration emission value
Uncertainty K = 1.5 m/s 2
The declared vibration total value and the declared noise
emission value have been measured in accordance with a
standard test method and may be used for comparing one
tool with another.
They may also be used in a preliminary assessment of
exposure.
WARNING
○ The vibration and noise emission during actual use
of the power tool can diff er from the declared total
value depending on the ways in which the tool is used
especially what kind of workpiece is processed; and
○ Identify safety measures to protect the operator that
are based on an estimation of exposure in the actual
conditions of use (taking account of all parts of the
operating cycle such as the times when the tool is
switched off and when it is running idle in addition to the
trigger time).
