1.1. ELECTRICAL SAFETY.
WARNING! It is the user’s 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 with portable products that are plugged
into an electrical supply not protected by an RCCB. If in 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 all portable electrical appliances, if used on business premises, to be 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 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 for wear and damage and all electrical
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 13 amp plug may require a fuse smaller than 13 amps 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.
1.1.8. DO NOT pull power plugs from sockets by the power cable.
1.1.9. DO NOT use worn or damaged leads, plugs or connections. Immediately replace or have
repaired by a qualified electrician. A UK 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’.
d) After wiring, check there are no bare wires, that all wires have been correctly
connected, that cable outer insulation extends beyond the cable restraint and that the 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. 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 cores of the cable
is important. We suggest 1.5mm2section as a minimum 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 2.5mm2section cable.
NOTE: The MS850PS has an electronic speed control, which requires a ‘clean’ and stable power supply. Normal 230V mains supply
is suitable. However, the output from many petrol driven generators may not be suitable for this tool. ‘Inverter’ type power
supplies provide a much more stable output and should present no problem.

LEAD PAINT WARNING! Paint once contained lead as a traditional ingredient. Contact with the dust from the removal of such paint is toxic
and must therefore be avoided. The following action must be taken before using machine as a sander:
1. User must determine potential hazard relating to age of paint to be removed. (Modern paints do not have lead content).
2. DANGER! Keep all persons and pets away from the working area. The following are particularly vulnerable to the effects of lead
paint dust: Expectant women, babies and children.
3. We recommend personal protection by using the following safety items:
A) Paint Spray Respirator (Sealey ref. SSP1699) B) PE Coated Hooded Coverall (Sealey ref. SSP266). C) Latex Gloves (Sealey
ref. SSP24).
4. Take adequate measures to contain paint dust, flakes and scrapings. Wear safety equipment, as in (3) above and thoroughly clean
all areas when task is complete.

Risk of Hand Arm Vibration Injury
The MS850PS Variable Speed Sander/Polisher, when operated in accordance with these instructions and tested in accordance with BS EN
28662-1:1993, ISO 8662-1:1988 and BS EN ISO 8662-8:1997 results in the following vibration emission declared in accordance with BS EN
12096:1996.
Measured vibration emission value: 5.6m/s² Uncertainty: 2.24m/s²
These values are suitable for comparison with emission levels of other tools that have been subject to the same test.
This tool may cause hand-arm vibration syndrome if its use is inadequately managed.
This is a ‘NO LOAD’ vibration figure.
A competent person should carry out a risk assessment following HSE guidelines.
Measurement results can be highly variable, depending on many factors, including the operator's technique, the condition of the work
equipment, the material being processed and the measurement method.
Recommended Measures to reduce risk of hand-arm vibration syndrome:
We recommend appropriate safety equipment is utilised and regular breaks for the operator are employed to reduce any residual risk of
fatigue or repetitive strain injury.

LOCKING
BUTTON
WARNING! Ensure you read, understand and apply the safety instructions in Section 1.
Ensure the power control switch is NOT locked on before plugging into the mains.
5.1. Hold the polisher firmly with one hand on the handle grip and the other on the side handle. To
select the required speed rotate the speed selector switch (fig.4.2) to the required speed 1 to 6.
5.1.1. To start the polisher press and hold down the safety lock button (fig.4.1) and squeeze the trigger.
When releasing the trigger, the safety lock button will engage, preventing the polisher from being
inadvertently started.
WARNING! The high speed settings are intended for sanding. If used for polishing an excessive
amount of surface material may be removed.
Note: As the rubber support disc is flexible, when sanding it should not be used head on, but at an
angle of approximately 10 to 20 degrees.
Contact your Sealey Dealer for details of compound heads and lambs wool bonnets.
6. MAINTENANCE
WARNING! Before attempting any maintenance ensure the unit is unplugged from
the mains power supply.
6.1. Keep the machine clean and dry. Do not use abrasives to clean the unit. Ensure all
external head screws are tight.
6.2. Clean regularly by blowing a jet of compressed air through side vents to ensure motor
ventilation is kept clear.
WARNING!Wear approved safety eye protection and, if necessary, respiratory
protection.
NOTE: The following maintenance must only be carried out by a technically qualified
person or an authorised Sealey service agent.
6.3. Check carbon brushes by removing each side screw (fig.5). Check to see if the brushes
are worn or cracked. If so, the brushes must be replaced to avoid sparking and damage
to the armature. Always change brushes as a pair. Use only genuine spare parts as
these are specifically designed for the machine. Failure to do so may be dangerous and
will invalidate your warranty.
6.4. After each 500 hours of use replace the gear head grease to prevent gear wear and
possible drive failure.
