MODEL 66-80 VIBRATORY DRIVER/EXTRACTOR
II. PREPARATION FOR OPERATION
F.BLEEDING HYDRAULIC CLAMP HOSES
1. When the vibrator and hydraulic clamp are shipped with all hoses attached
(between vibrator and clamp and five main hoses connected to the vibrator),
the hoses are usually full of oil and may be used immediately. However, if any
of the clamp hoses are connected at the job site or if air is present in hoses,
they must be bled prior to operation.
2. Read SECTION III - OPERATING INSTRUCTIONS.
3. Start and warm up the diesel engine in accordance with SECTION III-C -
STARTING AND WARMING UP ENGINE.
4. With the engine warmed-up and running at 1200 RPM, loosen the close-clamp
line at the hydraulic clamp. Turn the clamp switch on the remote-control
pendant to CLOSE. Wait until oil flows from the connection at the hydraulic
clamp. When oil flows without air, tighten the connection.
5. After the line has been bled, alternately turn the clamp switch to CLOSE and
OPEN to insure that the clamp is working properly. It may be necessary to
bleed the line more than once. The open-clamp line may also require
bleeding.
G. FILLING VIBRATOR PRESSURE HOSE
1. The vibrator is usually shipped with the vibrator hydraulic hoses full of oil and
the unit may be used immediately. However, if the pressure hose has been
removed from the vibrator, the hose should be allowed to fill with hydraulic oil
prior to fullspeed operation.
2. Read SECTION III - OPERATING INSTRUCTIONS.
3. Start and warm up the diesel engine in accordance with SECTION III-C -
STARTING AND WARMING UP ENGINE.
4. With the diesel engine running at 1800 RPM, the Vibrator hoses will fill with oil
in about 10 minutes. Do not press the START button on control pendant.
