Maintenance Schedules
Introduction
No one set of specific maintenance instructions will apply to all HiReach units. In
establishing a maintenance program or schedule, all pertinent operating data such as
environment, frequency of use and type of work performed, should be considered. The
HiReach maintenance program should be made a part of the standard program
employed for other units of similar characteristics.
Repairing or adjusting the HiReach or any of its components requires some
degree of mechanical ability. It is recommended that, insofar as possible, specific
operational crews, maintenance, and repair personnel, be regularly assigned to your
Elliott HiReach so that they may develop the necessary aptitudes and familiarity,
important to efficient, trouble-free service.
General Maintenance
Proper maintenance of an Elliott HiReach will result in many years of quality service.
The maintenance program shall require all daily, weekly, and annual inspections.
Additionally the program will include the checking of all mechanical, electrical, and
hydraulic equipment, as well as proper lubrication, and oil and filter changes.
The maintenance schedule will depend on the operational requirements and
environment of the HiReach but at a minimum should include the daily, weekly and
annual procedures set forth in this manual.
Daily Maintenance Schedule
1. Check the hydraulic oil level. If oil is low, inspect the hydraulic system for leaks,
and make all necessary repairs prior to adding oil and resuming operation.
2. Test control valves for proper operation.
3. Test boom control valve relief pressure. With warm oil and with engine on high
speed, retract boom, then continue to hold boom control lever in retract position.
Pressure gauge should read the same as the system pressure on the unit data
