IMPORTANT
Be aware of high oil temperature. Optimum
temperatures are 50–60 °C (120–140 °F).
Temperatures higher than 82 °C (180°F) could cause
seal damage and degrade the hydraulic oil. High
oil temperatures are often a symptom of another
problem.
5.6 Hydraulic Oil Drain
The hydraulic tank may occasionally need to be drained.
The drain plug is located at the bottom of the hydraulic
tank. Follow this procedure to drain the tank:
1. Allow the machine to cool before changing the oil.
Hot oil can cause burns if it contacts exposed skin.
It is best to change oil while the machine is warm to
keep the contaminants in suspension.
2. Have a drain pan ready that can hold 30+ L. (7+
US Gal.)
3. The oil drain plug is located under the machine, and
requires an Allen wrench to remove.
4. Clean area around drain and remove the Allen screw.
5.
Allow the oil to drain, then flush the tank.
6.
Replace the Allen screw, and refill the tank with
30 L
(7 US Gal.) of Dexron III hydraulic oil.
7. Dispose of used oil in a environmentally acceptable
fashion.
5.7 Hydraulic Oil Filter
The hydraulic filter needs to be cleaned at least every
100 hours or annually. The filter is located on top of the
hydraulic oil tank. Follow this procedure to clean the filter:
1. Allow the machine to cool before changing the oil
filter. Hot oil can cause burns if it contacts exposed
skin.
2. Have a drain pan ready to catch any dripping.
3. Find the oil return on the top of the reservoir, and re
-
mover the 3 screws on the filter cover.
4.
Remove the cover and pull out the hydraulic oil filter.
5. With the screen in hand, simply wash it out with diesel
fuel or varsol.
6.
Once clean inspect the filter mesh for any holes, per-
foration, rust or tears.
7.
Replace the clean filter into the tank, install and se-
cure the filter cover.
Check hydraulic reservoir oil
level. Top up as required.
