HYDRAULIC INSTALLATION
PREVENTION OF CONTAMINATION
1. A SHEET PILE DRIVER is harder on oil than using a bucket, so the oil is apt to
deteriorate and breakdown sooner. Neglect of the oil system can not only damage
the SHEET PILE DRIVER, but also cause problems in the carrier which could
result in damaged components. Care should be taken to check for contamination
of the oil and to change it if it is found contaminated. Oil sampling at regular
intervals is highly recommended.
❖
When the hydraulic oil shows low viscosity and bubbles, this indicates that the oil
is deteriorated. If the oil is dark brown and gives off an offensive odor, it is
severely deteriorated.
Change the oil immediately!
❖
When the oil is clouded, or the oil filter often becomes clogged, it indicates that the
oil is contaminated.
Change the oil immediately!
❖
To change the contaminated hydraulic oil, drain the hydraulic system completely
and clean components.
Do not mix new oil with the old!
2. Do not allow any contamination to mix with the oil. Take special care in preventing
contamination from entering the hydraulic system through the hose or tube
connection when changing the SHEET PILE DRIVER with the bucket.
3. Low oil level will cause heat build-up, resulting in deterioration of the oil. Also, it
may cause cavitation due to air mixing with the oil, leading to a damaged
compactor/driver and carrier components. Keep the oil at the proper level at all
times.
4. Do not use the SHEET PILE DRIVER at an operating temperature higher than
180°F (
80°C ). The proper operating oil temperature range is between 120°F
( 50°C ) and 180°F ( 80°C ). Since contaminated cooler fins causes reduced
efficiency of the cooler, keep the cooler fins clean at all times. Check the hydraulic
oil cooling system to be sure it is working effectively. The use of a heat gun is the
best way to evaluate if the cooler is working properly.
5. Water in the hydraulic oil will lead to damage of the SHEET PILE DRIVER and
carrier. Drain off water and foreign matter from the hydraulic tank at specified
intervals. When out of service, the SHEET PILE DRIVER should be stored
indoors.
CHANGING THE FILTER ELEMENT AND HYDRAULIC OIL
Change the filter element and hydraulic oil at the intervals described in the operation
manual of the backhoe or excavator, when using a hydraulic implement. Another
method is to set up an oil sampling schedule and change accordingly.
