This document provides instructions for using a labor hour manual for vehicle repairs. It explains that labor hours have been precisely set by experienced mechanics and adjusted for various experience levels. It provides indexes to search for codes and outlines rules for selecting codes, such as only using one code per repair and not using subordinate codes if a higher-level code applies. Codes are also provided for diagnosis time, component mounting/dismounting, and additional time required over standard hours. Failure to follow the instructions could result in warranty claim rejection.

1. The labor hours represented in this manualhave been set by Daedong qualified service mechanics. The flat rate for everyspecific task have been precisely measured and
based on the experience level of Daedong qualified mechanics. Labor hours have been adjusted to meet various levels of expertise.
The features of this manual are as follows;
1. Figures and reference numbers used in this manual are identical to those in the part manual to make searching easier.
2. As every individual part and component has its own code (except for hardware), it is easy to locate correct job codes faster.
3. The index attached to this manual serves as an additional measure for convenient searching of job codes.
How to use this manual
1. The same job code should not be used more than once since the labor hour for one job code is for both disassembly and re-assembly jobs.
2. In most cases, only one code should be used in one group (page) at a time. However,
* More than one job code can be used in one group when performing serveral different tasks.
* One job code can be used twice in case when both LH and RH parts are serviced at the same time.
3. Do not use subordinate job codes even if they are in deffernt groups. For example, “Bonnet R&R” and “Complete engine R&R should not be used at the same time
since “Bonnet R&R” is included in “Complete engine R&R”. In this case, only “Complete engine R&R” should be used.
4. Use of a separate warranty request form is required for each failure.
5. Use only one job code when servicing several adjacent or related parts. For example, if the bevel gear, its shaft and bearings are replaced the same time, use only the
top level job code applicable.
6. Time taken for reconditioning, resealing, overhaul, related oil draining and refilling, part flushing and adjustment after replacing parts are inclued in the labor hours of
these job codes.
Therefore, there is no need to include other job codes for such services.
7. Labor hours for diagnosis and implement R&R are not included the job codes. You may use the following job codes as needed with specific job descriptions on the
warranty request form:
* X999001: 0.5 hr. R&R of detachable main body of loaders, backhoes, mid-mount mowers, etc.
* X999002: 1.0 hr. Diagnosis time
* X999003: 2.0 hr. R&R of components used in the mounting of loaders, backhoes, mid-mount mowers, etc.
8. Failure follow the above instructions when drawing up the warranty request form(including on-line request) will result in rejection of your warranty claim.
9. If additional time is used for service, indicate details as to why and how many hours were needed in the description field of the form. Use of random job codes will result
in your warranty being rejected.
