Hydraulic System Check - Challenge CHAMP 150 Operator's Manual

5.0 Installation & Setup

5.3 Hydraulic System Check

The cutting/clamping mechanism of the CHAMP 150 is powered by a hydraulic system consisting of
an electric motor coupled directly to a hydraulic pump.
The hydraulic reservoir holds approximately 0.7 gallons (2.6 liters) of with ISO VG 46 hydraulic fluid. It
is filled at the factory but the level should be checked before operation. The tank is located at the
rear of the machine. Fluid level should be approximately 1" from the top of the tank (Figure 7). Add
fluid if necessary but avoid overfilling.
The hydraulic fluid should be checked weekly and changed AT LEAST ONCE-A-YEAR or after every
1,000 hours of operation.
NOTE: Use only ISO (International Standards Organization) Viscosity Grade 46, rust, oxidation, and
foam inhibiting, non-detergent hydraulic oil with a minimum flash point of 150°F (65°C). Oils other
than the recommended type will cause seals, cups, and O-rings to deteriorate. The proper
hydraulic oil can be purchased in 5 gallon containers from your authorized Challenge Dealer using
the Challenge part number: S-1991-3.
NEVER USE Automatic transmission oil or brake fluid as a substitute!
Oils other than the recommended type will cause seals, cups, and O-rings to deteriorate.
Unsafe operations conditions will result.
