STARTER

(3)

While crumbing worn battery with a plier, be careful not to

damage the soft pigtail.

(4)

In order to make soldering tin easy to be adhered, scrape the soft

pigtail end with a piece of sand paper.

(5)

Insert soft pigtail into the new brush hole and burn it on and be

sure no soldering tin exposed on the surface of brush.

DETECT SHORT CIRCUIT OF ROTOR WINDING

(1)

Put the rotor onto the growler.

(2)

Place the tagger above the rotor and keep it parallel to the central

axis of the rotor, slowly rotate the rotor and observe the tagger.

If it is not magnetized and doesn

t viberate, the rotor is normal.

NOTES:

CONDUCTING DETECTION AFTER COMPLETELY

CLEANING THE SURFACE OF ROTOR.

(3)

Check the insulation between commutator separators and the

iron core of rotor. If conduction fails, it

s normal.

DETECT OPEN CIRCUIT OF WROTOR INDING

(1)

Check whether conduction exists between all commutator

segment, if yes, its normal.

NOTES FOR ASSEMBLY
