FG15
In greasing, turn the sprocket and apply grease little by little so that grease is
applied uniformly.
When the timing belt is turned by your nger as shown in FG15, the sprocket
is turned.
(During one turn of the sprocket, apply grease on about 4 locations).
Note
(a) Do not remove the timing belt.
(b) Do not apply grease on the timing belt.
(4) Apply grease on the left worm gear.
Turn the timing belt and arrange the sprocket so that the hole of the right
sprocket is aligned to the position shown in the circle in the gure,
(so that the hole can be seen from the left worm gear or wheel).
Move the hole by means of turning the timing belt.
