Replacing Hydraulic Oil
To do so:
1.
Empty the hydraulic tank (see Emptying the Hydraulic Tank on page 90).
2.
With a clean dry cloth attached to a stick, remove all metal particles and debris accumulated at
the bottom of the hydraulic tank:
2 a.
Remove the access panel (see Figure 5-20).
2 b.
Remove the strainer. See
Cleaning the Strainer
on page 92.
2 c.
Clean or replace the strainer if necessary.
2 d.
Remove the return filter housing (see Figure 5-20).
2 e.
Insert your hand inside and clean the interior of the tank with a dry clean cloth.
2 f.
Clean the return filter housing with a dry clean cloth.
3.
Change the return filter element (see
Replacing Filter Elements
on page 95).
4.
Using a filtering screen, refill the tank with high quality oil until it reaches the 3/4 mark on the oil
gauge (see
Recommended Lubricants
on page 57 for specifications).
The entire system will require between 50 and 60 gallons of oil.
5.
If the suction line has been replaced, fill the line until oil reaches the pump (see
Pump Cavitation
on page 124).
Caution! Highly contaminated hydraulic fluid must be changed promptly to avoid damaging the
hydraulic system.
Caution!
It is not recommended to mix different brands and/or grades of oil in the hydraulic tank.
