The new grapple saw offers several benefits and advantages. The bar oil reservoir is integrated into the durable housing. The hydraulic circuit is simple and efficient. The hydraulic lines are routed for maximum protection and uptime — fully guarded and further protected by the through-tip boom system offered on the 234C and 250E series loaders.

A Tigercat grapple saw increases loader utility and versatility. In hardwood applications, it allows the operator to quickly trim large limbs and remove forks within the security of the operator’s station, reducing or eliminating reliance on ground personnel. In storm cleanup applications, the grapple saw is useful in untangling blowdown and cutting off root masses.

Telematics Firmware Update 4.0

New Functionality

The firmware V4.0 update offers enhanced features for a more comprehensive telematics experience including an updated LogOn web interface, with the inclinometer on the main screen and a dedicated text messaging icon.

With the latest update, LogOn puts more diagnostic and repair resource in your hands. Users with RemoteLog equipped machines now have the ability to perform an inducement unlock without the need for an unlock PIN.

In addition, the complete service manual for the machine can be accessed with LogOn.

Improved User Interface

A more intuitive and user-friendly interface for easier navigation.

For example, colour coding has been added to the Engine Diagnostics reporting screen to make it easier to comprehend the status of the test. This applies to all the tests available in Engine Diagnostics.

Expanded Diagnostic Tools

Tigercat Industries has developed more advanced and comprehensive tools for troubleshooting. The LogOn interface provides easy-to-understand steps to diagnose issues, directly referencing the appropriate section of the service manual. Several diagnostic tests can be initiated directly from LogOn to further diagnose the underlying reason for the fault code.

CAN Analyzer can now capture CAN data based on a trigger that can be set to either an ArbID or a PGN. The capture will stop after the specified time post trigger when the trigger is detected, or on the Stop button. A bulk recorder has been added that records all CAN traffic until clicking Stop or when the recording file size reaches a maximum size.

A complete Engine ECU Stores Data report is now generated when requesting stored data from the ECU.

Engine and aftertreatment diagnostic tests:

• The Compression Test detects relative low cylinder compression by controlling fuel and measuring crankshaft speed during engine cranking
• The Runup Test checks the fuel injection system for proper operation and performance
• The High Pressure Rail Test checks the fuel rail system for proper operation and performance, including fuel rail pump performance, system leakage, fuel pressure regulator tightness variation, and fuel pressure control instability
• The Exhaust Flap Valve Test runs a sequence of position requests to the exhaust flap actuator and compares the requested positions to the actual positions
• Several aftertreatment tests including the Urea Dosing System Test (UDST), Urea Dosing Pump Check (UDPC), and Urea Dosing Leakage Check (UDLC)
