Inspecting/Replacing.
Belts
Inspect the belts regularly for tension and wear. The oscil-
lator belt tension is not adjustable. If the oscillator belt
shows cracks or is slipping on the pulleys, replace the belt
with a new one. Refer to Figure 52 for proper belt tension
of the V-belts. When a V-belt is pinched together with
moderate force, there should be about 1
⁄
" between the

belt.
To replace the V-belts, refer to Changing Spindle Speed
on Page 32 to release belt tension.

Lubrication
Since all bearings are shielded and permanently lubricat-
ed, simply leave them alone until they need to be
replaced. Do not lubricate them.
An essential part of lubrication is cleaning the components
before lubricating them.
This step is critical because grime, chips, and dust build
up on lubricated components, which makes them hard to
move. Simply adding more lubricant will not result in
smooth moving parts.
