Hydraulic Power Unit Removal; Hydraulic Check - Challenge CHAMPION 305 Instructions And Parts Manual

6.0 Installation & Setup

6.7 Hydraulic Power Unit Removal

If installation requires that the machine pass through a doorway that is less than 49" but greater than
or equal to 42" wide, the machine should have been ordered from Challenge "knocked down" with the
table removed. If the machine must fit through a doorway that is less than 42" and greater than or
equal to 24-1/2", the hydraulic power unit must be removed on-site. To remove the hydraulic power
unit, follow the instructions below.
1. Disconnect the electrical conduits to the hydraulic motor, air blower, and hydraulic cooling
fan, junction box.
2. Remove the filler cap and use a transfer pump to move the hydraulic fluid into buckets.
3. Locate the hose that connects the manifold to the oil filter. Disconnect it from the filter.
Disconnect the hydraulic pump hose from the manifold. Attach the hose that was connected
to the manifold to the oil filter. Attach the hose that was connected to the filter to the
manifold. This will minimize oil leakage. After the unit is installed, reconnect the hoses to
their original location.
4. Remove the (4) bolts that attach the hydraulic assembly to the cutter base. They are located
at the bottom shelf the base.
5. USE EXTREME CAUTION WHILE REMOVING THE POWER UNIT. It is very heavy and
should be removed using a fork truck. CAUTION, the machine will be top heavy and may tip
easily with the power unit removed. Move the reservoir through the doorway on its side.
6. DO NOT ATTEMPT TO LIFT THE CUTTER BY PLACING STRAPS OR THE FORKS OF A
TRUCK UNDER THE CLAMP. This can damage the machine.
7. Reinstall the power unit, conduits, hoses, after the machine is in position. Refill the hydraulic
reservoir.

6.8 Hydraulic Check

The hydraulic reservoir is filled with 13-1/2 gallons of ISO VG 46 hydraulic oil at the factory. The fluid
level should be checked during installation, and at least once per week during normal operation. The
reservoir is located behind the cutter, beneath the table (Figure 3). Remove the filler cap to check the
fluid level. The fluid level should be approximately 2" (5cm) from the top of the tank.
NOTE: DO NOT OVERFILL. Overfilling may cause leakage when the machine is hot.
