Functional Description - Makita PW5000C Instruction Manual

20. Check damaged parts
Before further use of the tool, a guard or other part
that is damaged should be carefully checked to
determine that it will operate properly and perform
its intended function. Check for alignment of moving
parts, binding of moving parts, breakage of parts,
mounting, and any other conditions that may affect
its operation. A guard or other part that is damaged
should be properly repaired or replaced by an autho-
rized service center unless otherwise indicated else-
where in this instruction manual. Have defective
switches replaced by an authorized service center.
Do not use tool if switch does not turn it on and off.
21. Warning
The use of any other accessory or attachment other
than recommended in this operating instruction or
the catalog may present a risk of personal injury.
22. Have your tool repaired by an expert
This electric appliance is in accordance with the rel-
evant safety rules. Repairing of electric appliances
may be carried out only by experts otherwise it may
cause considerable danger for the user.
ADDITIONAL SAFETY RULES FOR TOOL
1. Always use eye and ear protection. Other per-
sonal protective equipment such as dust mask,
gloves, helmet and apron should be worn.
2. Always be sure that the tool is switched off and
unplugged before carrying out any work on the
tool.
3. Accessories must be rated for at least the speed
recommended on the tool warning label. Wheels
and other accessories running over rated speed
can fly apart and cause injury.
4. Check the backing pad carefully for cracks, dam-
age or deformity before operation. Replace
cracked, damaged or deformed pad immediately.
5. Check that the workpiece is properly supported.
6. Hold the tool firmly.
7. Keep hands away from rotating parts.
8. Make sure the abrasive disc is not contacting the
workpiece before the switch is turned on.
9. Do not leave the tool running. Operate the tool
only when hand-held.
10. Pay attention that the wheel continues to rotate
after the tool is switched off.
11. Do not touch the workpiece immediately after
operation; it may be extremely hot and could
burn your skin.
12. If working place is extremely hot and humid, or
badly polluted by conductive dust, use a short-
circuit breaker (30 mA) to assure operator safety.
13. Do not use the tool on any materials containing
asbestos.
14. Some material contains chemicals which may be
toxic. Take caution to prevent dust inhalation
and skin contact. Follow material supplier safety
data.
15. Always use the correct dust mask/respirator for
the material and application you are working
with.
16. Ensure that ventilation openings are kept clear
when working in dusty conditions. If it should
become necessary to clear dust, first disconnect
the tool from the mains supply (use non metallic
objects) and avoid damaging internal parts.
17. For additional protection against electric shock,
be sure to WEAR RUBBER GLOVES AND RUB-
BER BOOTS during operation.
18. When using the water feed, be careful not to let
water get into the motor. If water runs into the
motor, an electric shock hazard may result.
19. Never use the tool without an isolating trans-
former.
SAVE THESE INSTRUCTIONS.
Important Notes about Mains Connection for
110 Volts, 50 – 60Hz
Caution! Read and observe these precautions before
using the tool. Non-observance of these precautions may
lead to personal injuries and damage to the tool!
The tool was built according to the European Standards
EN50144-1 (safety of hand-held, motor-driven power
tools; here in particular section 20.19: power tools with
water connection) and EN60309-2 (plugs, receptacles
and couplings for industrial applications). When applying
these standards, the earth contact position of the plug-in
device may only be carried out in "12 o'clock position".
The tool has a plug-in device with a "12 o'clock" earth
ENB078-2
contact position.
However, since the European Standard EN60309-2 does
not provide a differentiation regarding the supply voltage
and this earth contact position, there is the possibility to
confuse the connection to an isolating transformer with
another output voltage (e.g. 230 V). When connecting
the tool to an isolating transformer, make absolutely sure
to use the correct output voltage (110 V, 50
This tool is designed exclusively for connection to an iso-
lating transformer with an output voltage of 110 V. Due to
its use in wet conditions (water connection on the tool),
this tool must never be connected to a power supply with-
out an isolating transformer.
Damages caused by inappropriate tampering with the
plug-in device are not subject to warranty or legal guar-
antee claims.
Contact your specialist supplier for an isolating trans-
former suitable for your tool.
