Within the hour, you could be tracing a pilot line on a Sumitomo SH330 or SH350 hydraulic excavator using this 677-page factory service manual (OEM ID SST-00-00-010EN), which covers four -5 variants. Hydraulics and electrics fill more than half of this Sumitomo SH350HD-5, SH350LHD-5, SH330 service manual PDF: port diagrams for the pump, valves, manifolds and motors, a pilot hose connection diagram, and electrical circuit and connector wiring diagrams. Error code tables and the air conditioner's panel self-diagnosis narrow a fault down before any connector comes apart. Swap the fuel pre-filter every 250 hours and the main filter every 500, and plan lifts around the SH330-5's 33,400 kg operating weight. Out there, it's you, the machine, and nobody to ask. Bookmarked and text-searchable, the PDF lets you check a component against the equipment tables and parts diagrams, so the part you order is right the first time.

Sumitomo SH330-5, SH330LC-5, SH350HD-5, SH350LHD-5 Common Problems This Manual Covers
Sumitomo SH330-5 monitor showing main unit input trouble code for sensor ground short or disconnection
Check the DTC display for the occurrence count and the initial and final occurrence times before touching anything. Match the code in the 7000 to 7199 input range against the list, then inspect that sensor's ground circuit and power supply for a short or disconnection. Reset the code and retest.
Manual Section: Main Unit Diagnostic Trouble Code List (Input)Main unit output trouble code for solenoid disconnection or short on a proportional valve circuit
Verify the code falls in the 7200 to 7399 output range, then identify which solenoid or proportional valve the main unit flagged. Inspect that solenoid's circuit for a disconnection or short, working back from the connector toward the main unit. Repair the fault, reset the code through the DTC display, and confirm it stays clear.
Manual Section: Main Unit Diagnostic Trouble Code List (Output)Mechanical trouble code for coolant or oil temperature, air cleaner clog, or return filter clog
Check which code in the 7400 to 7599 mechanical range is logged and note its occurrence count on the DTC display. For a coolant or oil temperature code, find the heat source before loading the machine again. For a clog code, inspect the air cleaner or return filter, clean or replace it, then reset the code.
Manual Section: Mechanical TroublesCAN bus communication time-out code between the ECM and computer S/B on the monitor
Check the logged code in the 7600 to 7799 communication range to see whether the ECM or the computer S/B dropped off the CAN bus. Inspect the CAN bus harness and connectors between those units against the connector wiring diagram in the Electrics Section, repair any damaged connection, then reset and watch the occurrence count.
Manual Section: Communication AbnormalityEPF restricting engine speed or stopping the engine on coolant or boost temperature or oil pressure drop
Verify whether the Engine Protection Feature is limiting speed because of coolant temperature, boost temperature, or a drop in oil pressure before chasing a fuel or power fault. Check the related temperature and pressure codes on the monitor, correct the underlying condition, and do not bypass the protection just to finish the shift.
Manual Section: EPF (Engine Protection Feature)Cab air conditioner blower motor, magnetic clutch, or air mix damper not operating
Test the system with the panel self-diagnosis function first and note what it reports. Then inspect the air mix damper, blow mode damper, refresh and recirculate damper, blower motor, and magnetic clutch in turn, following the Air Conditioner Section actuator inspection steps, and replace only the part that fails.
Manual Section: Air Conditioner Troubleshooting p. 565Frequently Asked Questions
How do I clear fault codes on a Sumitomo SH350HD-5?
To clear the trouble log on the SH350HD-5, open the DIAG (trouble diagnosis) screen. Once there, hold down the washer switch and the light switch simultaneously for 10 seconds to reset the log. p. 444
What are the torque specifications for the SH350LHD-5 track roller bolts?
The lower roller bolts for the SH350LHD-5 (M24 size) require a tightening torque of 902 - 1049 N•m. p. 664
What is the engine oil capacity for the SH330-5?
The engine oil pan capacity for the SH330-5 is 28.0 to 38.0 liters, excluding the remote oil filter. p. 483
What is the engine oil and filter change interval on the Sumitomo SH330-5, SH330LC-5, SH350HD-5, SH350LHD-5?
The engine oil and engine oil filter element should be replaced every 250 hours of operation. p. 535
How do I bleed air from the hydraulic pump after replacement?
After replacing the hydraulic pump, loosen the air bleed plug (1) and ensure oil oozes from the air bleed port (2). If it does not, remove the plug and fill the pump case with hydraulic oil through the port before tightening and running the engine at low idle. p. 616
