NEVER let the air compressor oil level fall
below the
lower mark. For normal
operation, the oil level should be to the full

the dipstick. Fill with recommended type oil
as listed in Table 7.
CAUTION CAUTION CAUTION CAUTION CAUTION 2. Raise the speed reducer adjustment lift handle slightly to
remove the V-belt from the 4-grove pulley.
3. Next, raise the lift handle all the way upwards until the
speed reducer unit is sitting in a vertical position. Lock unit
in this position.
4. There are 2 plugs (Figure 32) located on the metal cover of
the speed reducer unit.
5. Remove the bottom most plug ( weep hole ) from the unit. If
oil begins to seep out as the plug is being removed, it can
be assumed that the oil level is correct.
6. If oil does not begin to flow as the plug is being removed,
then it can be assumed that the unit requires oil.
7. Remove the oil fill plug and add SAE 90 wt. motor oil. DO
NOT over fill.

to have the speed reducer placed in an upright position (vertical).
Perform the following steps when checking the oil level of the
speed reducer unit:
1. Release the adjustment plate retaining chain (Figure 31)
that secures the speed reducer to the pump frame, then
remove the adjustment bolt from the slider cavity.
