SERVICING THE HYDRAULIC OIL:
1) At the top of the hydraulic tank, loosen the three bolts holding the
hydraulic return filter assembly cap (D) on the filter assembly base .
NOTE - the cap is spring loaded so be ready for the cap to “pop up”
as the bolts are removed! Be careful to not lose the large o-ring that
seals the cap to the filter assembly itself.
2) Pull out the return filter cartridge and inspect for metal shavings and/or
unusual debris.
3) Remove the return filter cup (A) while being careful not to lose the o-
ring (B) that seals the cup to the inside of the return filter assembly, it
can easily fall back into the tank if you do not capture it as you lift out
the filter cup.
4) Disconnect the hydraulic lines at the base of the tank and capture the
hydraulic oil in an appropriate container. Be prepared to capture
nearly 30 gallons of fluid while the reservoir tank drains.
5) Unscrew and remove the suction strainer (E) from the bottom of the
tank and replace with Cimline part number 172186.
6) Apply pipe thread tape and an appropriate amount of thread sealant to
the threads of the suction strainer (E) and any other pipe threads in
this assembly. The hydraulic JIC compression type connections do
not require thread tape or sealant.
7) Tighten all the components of the suction strainer (E) and related
hydraulic connections and leak test them before filling the tank
completely with hydraulic oil.
8) Reassemble the return filter assembly in reverse of the disassembly
instructions being careful to not drop the filter cup o-ring (B) into the
tank while replacing the filter cup (A) into the return filter base.
9) Place a new filter cartridge (C), Cimline part number 170407, into the
filter cup (A) and seat properly all the way into the cup.
10) Replace the filter cap (D) back onto the return filter assembly base. Be
careful to seat the large o-ring in the cap properly (F) in order to seal
the cap on the base. Alternate tightening the three lid screws to evenly
seat the lid and not pinch or distort the o-ring.
11) Fill the tank using high quality Conoco MV32 or equivalent hydraulic
oil. The maximum capacity of the hydraulic tank is 33 gallons, but the
actual fill level of hydraulic oil is between 27 and 28 gallons. Do not fill
the tank higher than the top level of the site gauge (G) on the tank.
Normal operating capacity of the hydraulic oil should be around the
top 3/4 on the site gauge window.

The melter operates at elevated temperatures

oil is cool before performing maintenance.
