| Commissioning
Bosch Rexroth AB, RE 15345-WA Version 11.2022,
8.3 Initial start up procedure
Important
• Follow section 2: Safety instructions .
• Make sure the driven system and driven machine are ready to run.
• Warn all personel in the area that the system will be started.
• Never operate the drive system with defective instruments or control elements.
• Keep inflammable materials away from the drive system.
• During start-up period, the hydraulic system will be cleaned from built-in dirt
particles, therefore keep an eye on the filter indicator during the entire start up
procedure.
STEP 1
Immediately before starting
• Check that the prescribed steps in section 8.1: Before commissioning have been
carried out.
• Check fluid level in the tank and refill to the nominal level, see 8.2: Filling up the
system with hydraulic fluid
• Check if any components need filling with clean hydraulic fluid, i.e. motor case.
• Check safety equipment.
• Make sure that all valves on the suction, pressure and inlet side of the pump, as
well as any valves on drain lines, are open.
• Check that cooling water is connected and turned on if a water-oil cooler is used.
• For adjustments and settings on the control system (if any) see special
instruction in attached order specific Hägglunds Fusion documentation.
STEP 2
Start with unloaded pump at short intervals
Starting of the drive system shall be carried out with a completely unloaded pump
in short intervals.
CAUTION
Wrong direction of rotation of the pump
Pump will be damaged. System contaminated
f
Make sure that the pump has the correct direction of rotation. The correct
direction of rotation is marked with a sign placed between electric motor and
motor plate, see Fig. 24 .
Rotating parts!
Risk of injury.
f
Do not touch rotating parts inside the inspection hole (see Fig. 24 ) or in the
zone of rotating parts.
• When the hydraulic fluid is cold some restarts may be needed to raise the charge
pressure.
• Check the charge pressure level and confirm with data and settings in attached
order specific Hägglunds Fusion documentation.
• If OK, the pump may be allowed to come on stroke and introduce flow into the
unloaded hydraulic system. Check that the charge pressure is still OK.
