ARCTIC TROUBLESHOOTING INTRODUCTION
Before beginning a task, review the associated maintenance procedure and determine the
amount of disassembly required to perform a test or inspection. Disassemble the machine
only as far as necessary to repair the damaged, broken, or faulty part.
1. This chapter provides information for identifying and correcting malfunctions that may develop during operation
of the 924H Loader.
2. The Arctic Troubleshooting Index in (WP 0394) lists common malfunctions which may occur, and refers to the
proper page in the Arctic Troubleshooting Procedures (WP 0395).
3. If you are unsure of the location of an item mentioned in troubleshooting, refer to General Information
(WP 0001), or Equipment Description and Data (WP 0002), or for referenced connector end views and their
location see Component Location and Connector End View (WP 0012).
4. Before performing troubleshooting, read and follow all safety instructions found in the Warning Summary at the
front of this manual.
5. The Arctic Troubleshooting Index (WP 0394) cannot list all malfunctions that may occur, nor can
troubleshooting list all tests or inspections and corrective actions.
6. When troubleshooting a malfunction:
a. Locate the symptom in Arctic Troubleshooting Index (WP 0394) that best describes the malfunction.
b. Turn to the page in Arctic Troubleshooting Procedures (WP 0395) that addresses the particular symptom.
Read each step before performing the test or inspection, review the electrical schematic (WP 0431,
Item 104) or hydraulic schematic (WP 0431, Item 105) before troubleshooting the machine. Perform the
test or inspection, observe the outcome, and perform the corrective action in the order listed until the
malfunction is corrected. When troubleshooting identifies a repair as a corrective action, perform the repair,
then return to troubleshooting to verify the malfunction is resolved and, if necessary, continue
troubleshooting. Do not perform any maintenance task unless the troubleshooting procedure instructs you
to do so.

a. MALFUNCTION. A visual or operational indication that something is wrong with the equipment.
