7.1 CHANGING THE HYDRAULIC OIL
Change the hydraulic oil at least once a year.
Make sure the ram is all the way in the upper position before draining any oil.
The drain plug is located at the bottom of the oil tank, along the back edge under the motor on the
hydraulic unit. The press holds nearly 12-1/2 gallons of oil so use a drain pan that has enough capacity.
The reservoir holds 8.5 gallons. The rest is in the cylinder and hoses and needs to be drained by
removing the hose and fitting from the bottom of the cylinder and allowing the oil to drain into a catch
pan. Then remove the hoses from the power unit and allow them to drain into a catch can as well.
•
Inspect Drained Oil. Check the oil for color and contamination.
•
If it is gray, that usually indicates there is moisture in the system.
•
A very dark color can be caused by overheating the hydraulic unit.
•
Metal particles visible in the oil can indicate worn out parts in the cylinder or the hydraulic unit.
•
If contamination is found, the source of the contamination must be found and repairs made.
The hydraulic system is sensitive to contamination and can be damaged.
•
If the inside of the tank is not clean, remove the top the oil tank and clean it thoroughly.
•
See SECTION 3.9 on for information on how to fill the system with oil.
•
Mobile DTE 10 Excel 46 or Mobil DTE 25 or similar hydraulic oil is recommended.
