Models

1. Park the machine on a flat, level surface. Disengage the PTO, engage the parking brake, turn off the engine, and remove the ignition key. Rear tires must be inflated to 15 psi (1,03 bar).

2. To check lift rod timing measure and record the distance between the lift pivots and the rod pivots. Repeat for other side of the unit. See Figure 42.
