Installing the hydraulic pump
For installation of the hydraulic pump, follow the same pro-

Cautions on starting the hydraulic pump
1. Fill the pump housing with hydraulic oil before starting.
• Loosen the air-bleeding plug (4), and tighten it again
when oil starts to flow out from the hole.
2. After starting, let the engine run in low idle for a while to
bleed all air from the circuit.
