1.1.
ELECTRICAL SAFETY.
p
WARNING! It is the users responsibility to read, understand and comply with the following:
You must check all electrical equipment and appliances to ensure they are safe before using. You must inspect power supply leads, plugs and all
electrical connections for wear and damage. You must ensure the risk of electric shock is minimised by the installation of appropriate safety
devices. An RCCB (Residual Current Circuit Breaker) should be incorporated in the main distribution board. We also recommend that an RCD
(Residual Current Device) is used with all electrical products. It is particularly important to use an RCD together with portable products that are
plugged into an electrical supply not protected by an RCCB. If in doubt consult a professional electrician. You may obtain a Residual Current
Device by contacting your Sealey dealer.
You must
also read and understand the following instructions concerning electrical safety.
1.1.1. The
Electricity At Work Act 1989
requires all portable electrical appliances, if used on a business premises, to be tested by
a qualified Electrician at least once a year by using a Portable Appliance Tester (PAT).
1.1.2. The
Health & Safety at Work Act 1974
makes owners of electrical appliances responsible for the safe condition of the appliance,
and the safety of the appliance operator.
If in any doubt about electrical safety, contact a qualified electrician.
1.1.3. Ensure the insulation on all cables and the product itself is safe before connecting to the mains power
supply. See 1.1.1. & 1.1.2. above and use a Portable Appliance Tester (PAT).
1.1.4. Ensure that cables are always protected against short circuit and overload.
1.1.5. Regularly inspect power supply, leads, plugs and all electrical connections for wear and damage,
especially power connections, to ensure that none are loose.
1.1.6.
Important:
Ensure the voltage marked on the product is the same as the electrical power supply
to be used, and check that plugs are fitted with the correct capacity fuse. A 13Amp plug may require
a fuse smaller than 13Amps for certain products (
subject to 1.1.10. below)
see fuse rating at right.
1.1.7. DO NOT pull or carry the powered appliance by its power supply lead. Products such as
welders must not be pulled or carried by their output cables.
1.1.8. DO NOT pull power plugs from sockets by the power cable.
1.1.9. DO NOT use worn or damage leads, plugs or connections. Immediately replace or have repaired by
a qualified Electrician. A U.K. 3 pin plug with ASTA/BS approval is fitted. In case of damage, cut off
and fit a new plug according to the following instructions (discard old plug safely).
(UK only - see diagram at right).
Ensure the unit is correctly earthed via a three-pin plug.
a) Connect the GREEN/YELLOW earth wire to the earth terminal E.
b) Connect the BROWN live wire to live terminal L.
c) Connect the BLUE neutral wire to the neutral terminal N.
After wiring, check there are no bare wires, that all wires have been correctly connected and that the wire restraint is tight.
Double insulated products are often fitted with live (BROWN) and neutral (BLUE) wires only. Double insulated products are always marked with
this symbol.
To re-wire, connect the brown & blue wires as indicated above. DO NOT
connect the brown or blue to the earth terminal.
1.1.10. Some products require more than a 13Amp electrical supply. In such a case,
NO
plug will be fitted.
You must
contact a qualified Electrician
to ensure a 30 amp fused supply is available. We recommend you discuss the installation of a industrial round pin plug & socket with your electrician.
1.1.11.
Cable extension reels
. When a cable extension reel is used it should be fully unwound before connection. A cable reel with an RCD
fitted is recommended since any product which is plugged into the cable reel will be protected. The section of the cable on the cable
reel is important. We recommend that at least 1.5mm
2
section cable but to be absolutely sure that the capacity of the cable reel is
suitable for this product and for others that may be used in the other output sockets, we recommend the use of 2.5mm
2
section cable.

GENERAL SAFETY
p
WARNING!
Ensure that all relevant Health and Safety, Local Authority, Control of Substances Hazardous to Health (COSHH), and General
Workshop Practice
Regulations
are strictly adhered to when using this equipment.
3
Familiarise yourself with products application & limitations, as well as the specific potential hazards peculiar to the
dust free vacuum system
.
p
WARNING!
Disconnect
dust free vacuum system
from mains power & air supply before changing accessories, servicing or performing maintenance.
3
Maintain the
dust free vacuum system
in good condition (use an authorised service agent).
3
Replace or repair damaged parts.
Use recommended parts only. Non authorised parts may be dangerous and will invalidate the warranty.
3
Locate
dust free vacuum system
in adequate working area, keep area clean & tidy and free from unrelated materials. Ensure there is adequate lighting.
p
WARNING!
ensure correct air pressure is used, maintained, and not exceeded for the appropriate sander attachment.
3
The air supply should be adequate to allow a
minimum
of 10.6cfm free air delivery to the sanding tool. This should be a
minimum
of 13cfm free air
delivered to the air inlet of the dust free vacuum system. We recommend the use of a 3HP (or more) compressor for one air tool, and twice the
compressor rating for the operation to two air tools.
3
Air supply must be delivered through a 3/8 internal diameter air hose. If you use a 5/16 internal diameter the performance of the tool may suffer.
3
Keep air hose away from heat, oil and sharp edges. Check air hose for wear before each use, and ensure that all connections are secure.
3
Before each use check attached tool for condition. If worn or damaged replace immediately.
p
WARNING!
The maximum wattage of any electrical tool operated from the dust free vacuum system must not exceed 800 Watts.
3
Ensure there are no flammable or combustible materials near the work area.
p
WARNING!
Always wear appropriate approved eye, face, mask, ear defenders, or protective clothing according to task being undertaken.
3
Keep hands and body clear of the sanders working parts when operating the
