MAINTENANCE & TROUBLESHOOTING
MAINTENANCE & TROUBLESHOOTING
Bleeding the Clamp Cylinders
As part of setting up a unit for service and
regular maintenance, air and old oil must be
bled from the hydraulic hoses.
Use caution near open hoses. Do NOT
touch any area with escaping oil. High
pressure oil is a serious hazard.
1. Engage clamp CLOSE to extend all
cylinders completely.
2.
Disconnect the clamp hose at the Clamp
OPEN Port on the Clamp.
3.
Place the loose hose end in a bucket that
can accept waste oil.
4. Engage clamp OPEN until all air has left the
line and there is at least 3/8ths of a gallon
in the bucket.
5. Release the clamp OPEN button and
reconnect the fitting to the clamp.
6. Engage clamp OPEN to retract all cylinders
completely.
7.
Disconnect the clamp hose at the Clamp
CLOSE Port on the Clamp.
8. Place the loose hose end in the bucket.
9. Engage clamp CLOSE until all air has left
the line, emptying approximately 3/8 gallon
into the bucket.
10. Release the Clamp CLOSE button and
reattach the fitting to the clamp.
The vibro is usually shipped with the hydraulic
clamp already attached and hooked up. If this
is not so, or the job requires it to be removed
and reattached later, a working knowledge of
how to change the clamp is necessary. All bolts
should be socket head cap screws. Do not use
grade five bolts.
If any one attachment bolt breaks
replace all of them. Never operate
the vibro without all attachment
bolts in place.
1.
Clean all drilled and tapped threads on the
bottom surface of the gearbox with brake
wash and a 1.5-6 UNC tap, removing any
metal fragments.
2. Clean the machined bottom of the gearbox
and the surface of the attachment. Make
sure the surfaces are flat, void of dirt, and
aren’t obviously damaged.
•
Failure to follow cleaning steps will
prevent bolts from tightening, causing
them to break.
3.
Orient the attachment holes with those of
the vibrator, centering it on the gearbox.
4. Using anti-seize on each bolt, insert the
center bolt first and work outwards. Do not
tighten bolts until all are installed or while
the attachment is hanging from the vibrator.
5. Tighten bolts according to the torque
specifications at the end of this manual.
6. After vibrating the first pile re-torque the
bolts.
