Manual Extract: Drain Pressure Procedure

This section provides a detailed procedure for draining pressure to ensure optimal machine performance. Follow the steps carefully to maintain the integrity of the machineu2019s hydraulics system.

Steps for Draining Pressure

1. Operate the machine to heat the oil to the operating temperature. To do this:

   • Run the engine at low idle.
   • Raise the parking latch levers and slowly move the direction control levers to FORWARD until the pins for the parking latch engage each drive sprocket.
   • Ensure that with the pins engaged, the machine does not move.

2. Stop the engine and safely remove the seat.

3. Install a tee between the hose and elbow. Use the following specifications:

   • The hose and elbow threads should be 1-1/16 – 12 flare.

   Connect a 100 psi (689 kPa, 6.8 bar) pressure gauge to the tee.

4. Start and run the engine at full throttle, then move the control lever to 1/2 stroke FORWARD and hold. Ensure the pressure is less than 25 psi (172 kPa, 2 bar).

5. Release the direction control lever, decrease the engine speed to idle, and stop the engine.

6. If the pressure exceeds the specified level, inspect for a bent hose that might restrict flow between the piston pump and the reservoir.

Usage and Maintenance Recommendations

• Ensure regular maintenance checks to avoid unexpected downtimes.
• Follow all safety protocols when operating machinery.
• Consult the manual for troubleshooting and detailed component specifications.
