Sealey MS900PS - Manual (Page 3)

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.6). 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.
5. OPERATION

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.5.2) to the required speed 1 to 6.
Speed Settings: Range from 1000rpm - 3000rpm
5.1.1. To start the polisher press and hold down the safety lock button (fig.5.1) 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.
