IMPORTANT
Be aware of high oil temperatures. Optimum temperatures
are 120–140 °F (50–60 °C). Temperatures higher than
180 °F (82 °C) could cause seal damage and degrade the
hydraulic oil. High oil temperatures are often a symptom of
another problem.
6.5 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 with capacity to hold the drained oil
from the tank and lines. Reservoir capacity is 7 US gal (30 L).
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 Dexron III oil.
Dispose of used oil in an environmentally acceptable fashion.
6.6 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.
The oil return is on the top of the reservoir. Remove the three
screws on the filter cover.
4.
Remove the cover and pull out the hydraulic oil filter.
5.
Wash the scren out with diesel fuel or Varsol®.
6.
Once cleaned, inspect the filter mesh for any holes,
perforations, rust or tears.
7.
Place the clean filter into the tank. Install and secure the
filter cover. Check hydraulic reservoir oil level. Top up as
required.
