To Service Motor And Switch; The Battery - Micron ELECTRAFAN 12 Instruction Manual

Unscrew the feed nozzle using a 6 B.A. or 5 mm 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
nozzle. 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 wa-
ter-based sprays and check for free liquid flow. Re-fit the bearing cover and the at-
omiser 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.

THE BATTERY

The Micron battery supplied is a Yuasa NP valve regulated lead acid sealed mainte-
nance free 17Ah (amp hour) 12V D.C. non-spillable type. Do not check electrolyte
specific gravity or add water, which will permanently damage the battery. Over dis-
charging will also damage the battery thus recharge as soon as possible after use.
When charging the battery using the recharger supplied, connect the recharger leads
to the battery terminals (after unplugging the ELECTRAFAN 12 from the battery)
and then switch on at the mains. If the ELECTRAFAN 12 is used with other 12V
D.C. batteries or rechargers consult the manufacturer for recharging information.
The special safety recharger supplied by Micron will avoid accidental overcharging
of the Micron battery.
