Maintenance - Evolution DWS 225 Manuel D'instruction

WARNING: Do not allow the rotating abrasive
disc to contact sharp objects such as protruding
nails, screws etc, or wall architecture such as
electrical boxes or switch plates. Damage to the
Sander or the wall fittings could result.

MAINTENANCE

Note: Any maintenance must be carried out with
the machine switched off and disconnected from
the mains/battery power supply.
Check that all safety features and guards are
operating correctly on a regular basis. Only use
this machine if all guards/safety features are fully
operational.
All motor bearings in this machine are lubricated
for life. No further lubrication is required.
Use a clean, slightly damp cloth to clean
the plastic parts of the machine. Do not
use solvents or similar products which
could damage the plastic parts.
WARNING: Do not attempt to clean by inserting
pointed objects through openings in the machines
casings etc. The machines air vents should be
cleaned using compressed dry air.
Excessive sparking may indicate the presence of
dirt in the motor or worn out carbon brushes.
Checking and replacing
the Carbon Brushes
Replace both carbon brushes if either has less than
6mm length of carbon remaining, or if the spring or
wire is damaged or burned.
To remove the brushes:
• Unscrew the plastic caps found at the
back of the motor. Be careful as the caps
are spring-loaded.
• You must replace both carbon brushes if
one has less than 6mm length of carbon
remaining, or if the spring or wire is damaged
or burned.
• Withdraw the brushes with their springs.

• If replacement is necessary renew the
brushes and replace the caps.
• Ensure the caps screw back freely.
Note: Used but serviceable brushes can be
replaced, but only as long as they are returned to
the same position, and inserted the same way
round, as they were removed from the machine.
• Run new brushes without load for
approximately 5 minutes. This will help
the bedding-in process.
Sanding Head Brush Skirt (Fig. 12)
Fig. 12
The Brush Skirt surrounds the Backing Pad to
which the abrasive discs are applied. The Brush
Skirt serves two (2) main purposes:
• It extends below the surface of the abrasive
disc so that it contacts the work surface
first, helping to prevent the rotating abrasive
disc from 'gouging' the work surface on first
contact.
• It helps contain the drywall dust
within the Swivel Head until the airflow from
the attached extraction machine sucks the
dust away.
