Re-fill Hydraulic Oil
1. Clean all surrounding debris and dirt off of the tank fill
opening area (8). (Hydraulic fluid must be kept completely
clean!)
2. Unscrew the filter cap and lift up to pull out the dipstick
(9).
3. Fill the tank with the proper recommended oil (see
specifications page) until the fluid reaches the upper
hole on the dipstick (9a).Do not operate the machine if
the oil level is below the lower hole (9b).
4. Replace the filter and cap.
Start Up Procedure
1. Make sure the drain plug and fill plug along with the
QD’s are properly installed and tightened.
2. Crank the engine, using the starter, for a short period
of time. This allows the system to begin filling with fluid.
Start the engine and run at the lowest possible speed.
Shut down the engine within 40 seconds if the pump or
motor begin making an unusual noise, indicating a lack
of oil, and be sure the reservoir is full and all the hoses
are properly connected.
4. Set the engine throttle at approximately 50% of maximum
throttle for a few minutes. This will purge trapped air from
the pump/control valve cir cuit.
5. Now the hydraulic cylinders circuits may be prepared.
Run the engine at normal operating speed. Using the
attachment motion lever, slowly, then at normal operating
speed, cycle the cylinders through all their motions until
all the air is bled off. The motions will be smooth and
powerful when all of the air is bled off.
7. Check the reservoir level, and add more clean fluid if
necessary.
The hydraulic system is now completely ready for
operation.
8. Clean up any spilled hydraulic fluid and check machine
for leeks.
Note: Hydraulic oil will need monitored if oil is lost while
interchanging attachments.
