ELECTRICAL SAFETY

  

WARNING!

 It is the responsibility of the owner and the operator  

to read, understand and comply with the following. You must 
check all electrical products, before use, to ensure that they 
are safe. You must inspect power cables, plugs, sockets and 
any other connectors for wear or damage. You must ensure 
that the risk of electric shock is minimised by the installation 
of appropriate safety devices. A Residual Current Circuit 
Breaker (RCCB) should be incorporated in the main distribution  
board. We also recommend that a Residual Current Device 
(RCD) is used. It is particularly important to use an RCD with 
portable products that are plugged into a supply which is not 
protected by an RCCB. If in any doubt consult a qualified 
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 that all portable 
electrical appliances, if used on business premises, are tested 
by a qualified electrician, using a Portable Appliance Tester 
(PAT), at least once a year.

1.1.2

The Health & Safety at Work Act 1974 makes owners of 
electrical appliances responsible for the safe condition of 
those appliances and the safety of the appliance operators. If 
in any doubt about electrical safety, contact a qualified 

 electrician.
1.1.3

Ensure that the insulation on all cables and on the appliance 
is safe before connecting it to the power supply. See 1.1.1 
and 1.1.2 and use a Portable Appliance Tester.

1.1.4

Ensure that cables are always protected against short circuit 
and overload.

1.1.5

Regularly inspect power supply cables and plugs for wear or 
damage and check all connections to ensure that none are loose.

1.1.6

Important: Ensure that the voltage marked on the appliance 
matches the power supply to be used and that the plug is 
fitted with the correct fuse - see fuse rating at below.

1.1.7

DO NOT

 pull or carry the appliance by the power cable.

1.1.8

DO NOT

 pull the plug from the socket by the cable.

1.1.9

DO NOT

use worn or damaged cables, plugs or connectors. 

Immediately have any faulty item repaired or replaced by a 
qualified electrician. When a BS 1363/A UK 3 pin plug is 
damaged, cut the cable just above the plug and dispose of 
the plug safely. Fit a new plug according to the following 
instructions (UK only).

a) Connect the GREEN/YELLOW earth wire to the earth 
terminal ‘E’.

 b) 

Connect the BROWN live wire to the live terminal ‘L’.

c) Connect the BLUE neutral wire to the neutral terminal ‘N’.
d) After wiring, check that there are no bare wires, that all 
wires have been correctly connected, that the cable outer 
insulation extends beyond the cable restraint and that the 
restraint is tight.

Double insulated products, which are always marked with this 
symbol     , are fitted with live (brown) and neutral (blue) wires 
only. To rewire, connect the wires as indicated above. 

 DO 

NOT connect either wire to the earth terminal.

1.1.10 Products which require more than 13 amps are supplied 

without a plug. In this case you must contact a qualified 
electrician to ensure that a suitably rated supply is available. 
We recommend that you discuss the installation of an 
industrial round pin plug and socket with your electrician.

1.1.11  If an extension reel is used it should be fully unwound before 

connection. A reel with an RCD fitted is preferred since any 
appliance plugged into it will be protected. The cable core 
section is important and should be at least 1.5mm², but to be 
absolutely sure that the capacity of the reel is suitable for this 
product and for others which may be used in the other output 
sockets, we recommend the use of 2.5mm² section cable.

1.2

GENERAL SAFETY

 

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.

Familiarise yourself with the applications, limitations and 
hazards peculiar to the dust free vacuum system.

 

WARNING!

 

Disconnect dust free vacuum system from mains 

power and air supply before changing accessories, servicing 

 

or  performing maintenance.

 

Maintain the dust free vacuum system in good condition (use 
an authorised service agent).

Replace or repair damaged parts. 

Use recommended parts 

only. Unauthorised parts may be dangerous and will invalidate 
the warranty.

Locate dust free vacuum system in a suitable work area. 
Keep area clean and tidy and free from unrelated materials. 
Ensure there is adequate lighting.

WARNING!

 Ensure correct air pressure is used, maintained, 

and not exceeded for the sander attachment.

The air supply should be adequate for a 

minimum

 of 10.6cfm 

free air delivery to the sanding tool. There 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.

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. 

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. 

Before each use check attached tool for condition. If worn or 
damaged replace immediately.

WARNING! 

The maximum wattage of any electrical tool 

operated from the dust free vacuum system must not exceed 
1200 watts.

Ensure there are no flammable or combustible materials near 
the work area.

WARNING! 

Always wear appropriate approved eye, face, mask, 

ear defenders, or protective clothing according to task being 
undertaken.

Keep hands and body clear of the sanders working parts 
when operating the dust free vacuum system.

Keep children and unauthorised persons away from the 
working area, and DO NOT allow untrained persons to 
operate the dust free vacuum system.

 

DO NOT use the dust free vacuum system for any purpose 
other than that for which it is designed.

 

DO NOT pull or yank the electrical leads, air hoses or vacuum 
extraction hoses attached to the dust free vacuum system.
