Maintenance Guideline for Hirer, Maintenance System for Hiring Equipment
1 DOCUMENTS FOR THE MAINTENANCE SYSTEM
The documents, namely maintenance guideline, maintenance plan and maintenance manual for the
hiring equipment were prepared by the Groundwater Development and Management Capacity
Development (DDCAP) Project, in order to manage the maintenance system for the hiring
equipment. The roles and the contents of each document are summarized as follows.
This is Document 3: Maintenance Manual for the Hirer for the maintenance works for hiring
equipment.
Document 1: Maintenance Guidlene
The guidline stipulates the roles and responsibility of both lessee (DDCA) and lesser (private
drilling company). The gidline is a principle for the operation of the maintenance system. The
guidline is derected to a system to hire drilling equipment and machinery. The guideline aims to
maintain the equipment and machinery for hiaring as good working condition in order to
accommodate demand of the private drilling companies.
Document 2: Maintenance Plan
The maintenance plan demonstrates the plans for the periodical service, sparparts, consumable
parts, tools, procurement, staff assignment, training and budjet. The maintenance works for the
hiring equipment should be carried out according to the maintenance plan.
Document 3: Maintenance Manual
The separate maintenance manuals for Owner (DDCA) and Hirer (private drilling company) were
provided. The manuals indicate the method and procedures of the maintenance works.
2 PURPOSE OF THE MAINTENANCE MANUAL OF HIRING
EQUIPMENT
The maintenance manual of hiring equipment indicates the methods and procedures of actually
conducting the maintenance and management of hiring equipment, as stipulated in the guideline for
hiring management. This manual will be revised according to the conditions of the hiring
equipment, and the revision will be conducted by the the maintenance section of DDCA.
3 DAILY MAINTENANCE OF HIRING EQUIPMENT BY HIRER
The hirer (private drilling company) is required, following the daily service manual, to fill in the
items on the “daily service check sheet” concerning the condition of the equipment before and after
use. The private drilling companies are required to accurately fill in the sheet as the record
indicates the daily condition of the equipment as well as relevant information for detecting the
cause of problems.
3.1 DAILY SERVICE CHECK SHEET
The daily service check sheet will be used for the following hiring equipment:
[Form B-1] Truck Mounted Drilling Rig
[Form B-2] Support trucks (Cargo trucks, Cargo truck with crane and Water tank truck)
[Form B-3] Trailer Mounted Air Compressor
[Form B-4] Trailer Mounted Mud Pump
[Form B-5] Trailer Mounted Pumping Test Unit

Maintenance Manual of Hiring Equipment for Hirer (Private Drilling Company)
3.2 CONTENTS OF DAILY SERVICE CHECK SHEET
The following contents will be filled in the daily service check sheet before and after the operation
of the hired equipment:
Date
Mileage (operated hours) before operation, mileage (operated hours) after operation
Time at the start and end of operation
The condition will be judged in these four categories: good, not good, bad, no relevance
When the condition is confirmed to be “not good”, the private company must swiftly report
to the DDCA’s Head of maintenance workshop, and the equipment must be closely
monitored when in use.
When the condition is confirmed to be “bad”, the private company must swiftly report to the
DDCA’s Head of maintenance workshop.
Any comments on the condition of the equipment will be filled in the “remarks” column.
Table 1 shows an example of how to fill in the check sheet is presented below, using the following
case of a vehicle problem as an example:
No problems were found with the vehicle during operation on Sept. 1, 2012
Oil leakage from the hydraulic system was detected after the operation. On receiving this
report from the user, the DDCA mechanical workshop instructed to continue operation while
paying attention to the amount of the oil, as the oil leak was small, and would not interfere
with the operation.
Water leakage from the radiator was detected after operation on Sept. 2.
The DDCA mechanical workshop conducted repairs of the oil leakage of the oil pressure
system and the water leakage of the radiator on the Sept. 3, by dispatching a mechanic to the
drilling site. The vehicle was not operated on the 3rd.
On the 4th, the repair was complete and the vehicle was confirmed to be in good condition.
