Maintenance And Inspection - HIKOKI DH 52ME Mode D'emploi

GREASE REPLACEMENT
This Rotary Hammer is of full air-tight construction to protect
against dust and to prevent lubricant leakage.
Therefore, this Rotary Hammer can be used without
lubrication for long periods. Replace the grease as described
below.
Grease Replacement Period
After purchase, replace grease after every 6 months of
usage. Ask for grease replacement at the nearest authorized
Service Center.

MAINTENANCE AND INSPECTION

1. Inspecting the drill bits
Since use of a dull tool will cause motor malfunctioning
and degraded effi ciency, replace the drill bit with new
ones or resharpen them 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. Replacing supply cord
If the replacement of the supply cord is necessary, this
has to be done by the manufacturer of this agent in order
to avoid a safety hazard.
CAUTION
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
country must be observed.

IMPORTANT
Correct connection of the plug
The wires of the main lead are coloured in accordance
with the following code:
Blue: — Neutral
Brown: — Live
As the colours of the wires in the main 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
EN60745 and declared in accordance with ISO 4871.
Measured A-weighted sound power level: 113 dB (A)
Measured A-weighted sound pressure level: 102 dB (A)
Uncertainty K: 3 dB (A).
Wear hearing protection.
Vibration total values (triax vector sum) determined
according to EN60745.
Hammer drilling into concrete:
Vibration emission value ah, HD = 14.0 m/s
Uncertainty K = 1.5 m/s
2
Equivalent chiselling value:
Vibration emission value
Uncertainty K = 1.5 m/s
2
The declared vibration total value has been measured in
accordance with a standard test method and may be used
for comparing one tool with another.
It may also be used in a preliminary assessment of exposure.
WARNING
○ The vibration emission during actual use of the power
tool can diff er from the declared total value depending in
the ways in which the tool is used.
○ 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).
NOTE
Due to HiKOKI's continuing program of research and
development, the specifi cations herein are subject to
change without prior notice.
