10. Maintenance
Replacing the Filters
The filters should be inspected every time the unit
is emptied and particularly if any reduction in
performance is noted.
The paper filters trap fine dust, and to prevent
becoming clogged should be renewed regularly (part
no. DX1500E).
The cartridge filter should be cleaned at the
same time, and should be renewed annually or
immediately if showing signs of damage or wear
(part no. DX1500F).
To Change the filters:
1. Remove the hood unit
(Fig 10.1)
.
2. The cartridge filter is contained within the paper
filter bag
(Fig 10.2)
, it can be removed by unfolding
and carefully lifting out.
NOTE:
Care should be taken when
handling soiled or contaminated filter bags
and cartridges. As certain fine dusts can be
harmful. Always wear suitable PPE for additional
protection.
3. The paper bag can be removed from around the
cartridge filter and disposed of.
4. The cartridge filter can then be carefully cleaned
with a vacuum cleaner, or renewed if required.
5. Place the cartridge filter inside a new paper filter
bag and fold the top edges of the of the paper filter
bag down inside the cartridge, noting not to fold the
edges any more than
50mm inside the cartridge
filter.
Following instructions from the ‘Operations
and Assembly’ Section of this manual
6. Replace the filters into the machine by pressing
them back into position.
7. Replace the hood unit.
Renewing Motor brushes
The motor carbon brushes should not need replacing
for at least 2000 hours. These are contained within
the horizontal housings on top of the motor,
and once removed from the housings, cannot be
reinserted.
1. To fit new carbon brushes, first ensure the
machine is switched off and disconnected from the
power supply.
2. Remove the lid cover from the head of the
machine by unscrewing the three cross head screws
holding it in place, to gain access to the top of the
motor
(Fig 10.3)
.
3. Remove the brush carrier from the motor by
unscrewing the two screws that secure it
(Fig 10.4)
.
4. Push in the location tab, remove the spade
terminal connector and slide the brush housing out
of the carrier
(Fig 10.5)
.
5. Replace brush and brush housing with new ones
and follow these steps in reverse to attach back
onto the motor.
NOTE:
When replacing motor brushes,
take care not to allow dust,
oil, water etc. to get into the motor.
