How to move the orbital sander
For optimum operating effi ciency, alternately move the
sander forward and backward at a constant speed and
balance.
After installing new sanding paper
Movement of the sander may tend to become unsteady
after new sanding paper has been installed, because of
the new, coarse grain of the paper. This can be avoided
by slightly tilting the sander forward or backward during
sanding or polishing. Sander movement will become
steady as the sanding paper surface becomes properly
abraded.

MAINTENANCE AND INSPECTION

1. Empting and cleaning the Dust Bag
If the dust bag contains too much saw dust, dust
collection will be aff ected. Empty the dust bag when it
gets full.
Remove the dust bag, open the fastener, and dispose of
the contents.
2. Inspecting the sanding paper
Since use of worn-out sanding paper will degrade
effi ciency and cause possible damage to the pad,
replace the sanding paper as soon a excessive abrasion
is noted.
3. 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.
4. 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.
5. Servicing
Consult an authorized Service Agent in the event of
power tool failure.
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.
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 each 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: 94 dB (A).
Measured A-weighted sound pressure level: 83 dB (A).
Uncertainty K: 3 dB (A).
Wear hearing protection.
Vibration total values (triax vector sum) determined
according to EN60745.
Sanding a horizontal steel plate:
Vibration emission value
Uncertainty K = 1.5 m/s
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.
