FLUID LEVEL
Procedure for checking the fluid level in the fluid reser-
voir is to be found on Page 116.

REFILLING THE HYDRAULIC
SYSTEM
1. With the car raised on a hoist, remove the reservoir (A),
Figure 186, and fill to the fluid level line with hydraulic fluid.
NOTE: Inasmuch as the two top operating cylinders have
a fluid capacity nearly double that of the reservoir, more
than one filling is necessary before the folding top can be
raised or lowered with the exclusive use of the hydraulic
system.
2. Raise and lower the top several times to admit fluid and
expel air from the system. It will be necessary to assist
the movement of the top manually until sufficient fluid
has entered the system to afford independent hydraulic
operation.
3. Remove reservoir and refill as necessary to fluid level
line. Operate all windows several times to expel air from
that part of the system.
4. With all hydraulic units operating satisfactorily, lower all
windows and the folding top and again check the hy-
draulic fluid level in the reservoir. The fluid in the reser-
voir should now be up to the fluid level line.
5. Check all hydraulic connections for leaks.
BLEEDING HYDRAULIC SYSTEM
Bleeding, as ordinarily meant by the term, is unneces-
sary with the Hydro-Lectric system. An air vent is provided
in the pump body to allow air to enter and escape from the
system . Operating the units several times while refilling the
system frees the lines and cylinders of air.
HYDRAULIC PUMP PRIME
When the motor and pump operate, but top and win-
dows fail, lack of "prime" in the pump is indicated. Make
sure the fluid level is up to the line on the fluid reservoir. To
check for priming, remove seat cushion and disconnect
flexible line from TEE in front of pump. This flexible line is
the pressure line from the side of the pump. Insert this
flexible line into a container to avoid spilling fluid and
operate pump briefly two or three times. NO fluid flow from
this line indicates the pump lacks prime.
To prime the pump, disconnect the fluid re turn line at
the front of the pump. Hold thumb tightly over return port
in pump and run pump a few seconds until fluid is expelled
from the pressure line. Reconnect lines and check the fluid
level in the reservoir, Figure 186.
If pump frequently loses prime, a leak is indicated at
some point in the return line.
