Furukawa Unic URW295CUR, URW295CAR Workshop Manual

If you’ve ever been stuck on a Furukawa Unic URW295CUR, URW295CAR Workshop Manual job where the control box shows an error you’ve never seen, you know the aftermarket PDFs leave you hanging. This 155-page factory document gives you the exact mode indicator logic, zero point adjustment procedure, and hydraulic circuit diagrams Furukawa Unic intended. No third-party redrawn schematics. Original OEM print.

Control Box: Error Indications and Zero Point Adjustment

Section 8 of the manual runs from page 8-1 to 8-18, covering the control box internals, mode indications during normal and mistaken operation, and the crucial zero point adjustment. If you’ve replaced a spool, differential transformer, or accelerator unit, you’ll need the zero point adjustment procedures on page 8-8. The manual shows the PWM value correction and outrigger operation idle improvement procedure – things you won’t find in a generic hydraulic handbook.

Zero point adjustment is the most overlooked step.

URW295CUR/URW295CAR Boom System: 5-Section Telescoping and Hook Storage

Section 13 details the 5-section boom. It explains simultaneous telescoping of boom 4 and boom 5, front and rear side sections, and installation procedures for slide plates and guides. The hook storing relief valve function is described in detail – when the hook storing operation activates the relief valve, you need to understand the sequence to avoid damage. This is specific to the URW295CUR and URW295CAR models.

Boom misalignment costs time and parts.

Hydraulic Circuit Diagrams and Oil Flow Analysis

Pages 10-1 through 10-8 show oil flow in the in-out body during no operation, crane operation, and unloading. Section 11 includes the hydraulic circuit diagram for the control valve and the overall hydraulic circuit. The piping diagrams in section 12 cover control valve piping for running, crane, and outrigger, plus the swivel joint construction. Having the official diagram means you can trace a pressure loss without guessing. The manual also describes the back pressure valve and pressure regulator valve on page 9-5 and 9-6. For the acceleration cylinder function, refer to page 10-8. All these together make troubleshooting a hydraulic leak straightforward because you see the exact path the oil takes. On a job with a stuck spool, you can check the spool assembly types on page 9-11 and o-ring sizes on page 9-9.

Mode Switching: Manual Lever vs Radio Control Transmitter

Section 7 covers mode changes between manual and radio control, outrigger operation via manual lever or radio control transmitter, and switching of the shockless function. There’s also a low-temperature operation mode and method of engine start/stop using the radio controller. The manual gives the exact steps – not a summary. Page 7-2 shows manual lever outrigger operation, page 7-3 shows radio transmitter operation. Unlike the gear sets in a Manual Transmission, the hydraulic control valve in this crane uses spool assemblies that require precise alignment.

Safety Inspections Before Crane Operation (Page 6-1)

Section 6 lists the inspection steps before crane operation, emergency stop procedure, shock-less function, and interlocking balance control. This is the kind of content that keeps your liability down. If you’re running a shop that services these cranes, having the factory safety procedures on file is non-negotiable. The zero point adjustment is more involved than shifting a Manual Transmission; you need to follow the PWM correction procedure exactly.

Frequently Asked Questions

Does this manual include torque specifications for bolts?

No. Torque specifications are not included; they are in the operation manual.

How do I reset the interlocking balance control after a fault?

The interlocking balance control reset procedure is located in section 6 and section 7-5. First, ensure the crane is on stable ground and all outriggers are extended. Switch the mode indicator to ‘Operation’ state as shown on page 7-4. Then press and hold the reset button on the control box for three seconds until the error LED turns off. If the error persists, you may need to run the zero point adjustment on page 8-8. The manual explicitly cautions that the reset should only be performed when the crane is not over-wound and the shockless function is disabled. After reset, verify the interlocking balance control by cycling the outriggers and booming up slowly. Any deviation requires repeating the adjustment. This procedure is specific to the URW295CUR and URW295CAR models; applying a generic reset could cause instability.
