Using a 90° scribe, lift the brush tension spring to allow brush installation. Insert
brushes into slots ensuring that the curvature of the brush matches the armature.
Brushes should slide in brush guides freely without restriction. After insertion of
the brush, do not allow the spring to slap against the brush as this can cause
damage to the brush resulting in premature failure.
CAUTION:
Do
NOT
overextend the brush spring farther than necessary to install the
brush as this can change the spring tension.
