To Service Motor And Switch; Replacement Of Mains Cable - Micron Electrafan 240 Instruction Manual

Unscrew the feed nozzle using a 6.BA or 5mm AF spanner and clean carefully with a
soft wire, e.g. fuse wire. Clean the feed line with a pipe cleaner. Re-fit the feed noz-
zle. Before re-fitting the atomiser assembly, screw on a spray bottle filled with either
kerosene (when using ULV formulations) or water and detergent (when using water-
based sprays) and check for free liquid flow. Re-fit the bearing cover and the atom-
iser assembly, and tighten as previously described.

TO SERVICE MOTOR AND SWITCH

(Only to be carried out by qualified Service Engineers)
Proceed as follows:
1. Remove handle caps and guard retainer screws.
2. Remove outer fan guard and circular guard ring.
3. Remove fan and inner guard.
4. Remove fan drive pin (tight push in), slinger and washer.
5. Remove switch cover (two retainer screws near fan shaft). Note position of large
'O' ring and ensure this is re-fitted to the motor housing before re-assembly.
6. Gently pull switch cover clear of the fan shaft and move to one side to expose mo-
tor brushes, switch and internal wiring.
N.B. Replacement brushes for the motor are available from Micron. If the armature
or bearings need replacing, a new motor will be required.
When re-assembling:
1. Reverse the above procedure.
2. Make sure the fan drive pin is located in the grooves in the fan hub. This prevents
the fan shaft from rotating when the fan nut is tightened.
REPLACEMENT OF MAINS CABLE (see also 'ELECTRICAL SAFETY')
Use 5m of PVC sheathed and insulated 3 core flexible cable with 1mm² (32/0.2mm)
conductors. Strip outer sheath and refit heat protection sleeving to individual leads
using original lead as a pattern.
The diagram below illustrates the correct connections to be made when replacing the
cable:
green and yellow wire to the terminal marked
blue wire to the terminal marked N (Neutral)
brown wire to the terminal marked L (Live)
(Earthed)
