Place absorbent cloth below the reservoir filler plug.
Remove the filler plug and check the fluid level. It should be level with
the bottom of the filler plug hole. If fluid appears excessively low, check for
leaks or restrictions in the hydraulic lines, loose or broken fittings, and/or
damaged cylinders. If the system is damaged, service or replace as necessary
and bleed the system as described below.
System Bleeding
Remove the filler plug from the reservoir and fill to the bottom of the
filler plug hole with type A transmission fluid.
With the plastic filler plug installed and engine running, cycle the top
a sufficient number of times to adequately purge the system of air pockets.
Excessive air will be noted in the transparent lines. Replenish the reservoir
as necessary during the bleeding operation. Fill to the proper level and
tighten the filler plug. When cycling the top, make certain that the cylinders
have freedom of movement.
