Also inspect the roll cage o for cracks and ensure

2. Check the minimum battery voltage at the Grey &

3. Inspect the armature plate e for a consistent wear
pattern. There should be two distinct wear bands r
(one band inside the other). If only one band of wear
is present (or if there is wear between the two bands,
inspect the coil area as indicated in Step 4. A band
with an interrupted wear mark may indicate a warped
plate, which may cause intermittent operation.
