Section 1 - Scheduled MaintenanceOperator’s Responsibility for Maintenance
Hydraulic System & Component Maintenance and Repair
The following points should be kept in mind when working on the hydraulic system or any component:
1. Any structure has limits of strength and durability. To prevent failure of structural parts of hydraulic components, relief valves which limit pressure to safe operating values are included in the hydraulic circuits.
2. Tolerance of working parts in the hydraulic system is very close. Even small amounts of dirt or foreign materials in the system can cause wear or damage to components, as well as general faulty operation of the hydraulic system. Every precaution must be taken to assure absolute cleanliness of the hydraulic oil.
3. Whenever there is a hydraulic system failure which gives reason to believe that there are metal particles or foreign materials in the system, drain and flush the entire system and replace the filter cartridges. A complete change of oil must be made under these circumstances.
4. Whenever the hydraulic system is drained, check the magnets in the hydraulic reservoir for metal particles. If metal particles are present, flush the entire system and add a new change of oil. The presence of metal particles also may indicate the possibility of imminent component failure. A very small amount of fine particles is normal.
5. All containers and funnels used in handling hydraulic oil must be absolutely clean. Use a funnel when necessary for filling the hydraulic oil reservoir, and fill the reservoir only through the filter opening. The use of cloth to strain the oil should be avoided to prevent lint from getting into the system.
6. When removing any hydraulic component, be sure to cap and tag all hydraulic lines involved. Also, plug the ports of the removed components.
NOTE
Samples of hydraulic oil should be drawn from the reservoir and tested annually. These samples should be taken when the oil is warmed through normal operation of the system. The sample should be analyzed by a qualified lubrication specialist to determine if it is suitable for continued use.
Oil change intervals will depend on the care used in keeping the oil clean, and the operating conditions. Dirt and/or moisture cotamination will dictate that the oil should be changed more often. Under normal use and operating conditions, the hydraulic oil should be changed every two years. Refer
to Table 1.2 of this manual.
7. All hydraulic components must be dis-assembled in spo t l e s s ly cl e a n surr o u n d ings. Du ring disassembly, pay particular attention to the identification of parts to assure proper reassembly. Clean all metal parts in a clean mineral oil solvent. Be sure to thoroughly clean all internal passages. After the parts have been dried thoroughly, lay them on a clean, lint-free surface for inspection.
8. Replace all O-rings and seals when overhauling any component. Lubricate all parts with clean hydraulic oil before reassembly. Use small amounts of petroleum jelly to hold O-rings in place during assembly.
9. Be sure to replace any lost hydraulic oil when comple ting the installation of the repaired component, and bleed any air from the system when required.
10. All hydraulic connections must be kept tight. A loose connection in a pressure line will permit the oil to leak out or air to be drawn into the system. Air in the system can cause damage to the components and noisy or erratic system operation.
Maintenance Hints
Three simple maintenance procedures have the greatest effect on the hydraulic system performance, efficiency and life. Yet, the very simplicity of them may be the reason they are so often overlooked. What are they? Simply these:
Change filters annually. The filters will need 1. to be changed more often depending on the operating conditions. Dirty, dusty, high mo isture environments may cause the hydraulic system to be contaminated more quickly. Maintain a sufficient quantity of clean hydraulic 2. oil of the proper type and viscosity in the hydraulic reservoir. Keep all connections tight.3.

OUP - Overall Uniform Pressure is a measure of the average load the aerial platform imparts on the whole surface directly underneath it. The structure of the operating surface (beams, etc.) must be able to withstand more than the indicated values above.
The LCP or OUP that an individual surface can withstand varies from structure to structure and is generally determined by the engineer or architect for that particular structure.
min - Total aerial platform weight with no options
max - Aerial platform weight + all options + full capacity
LCP - Locally Concentrated Pressure is a measure of how hard the aerial platform presses on
the areas in direct contact with the floor. The floor covering (tile, carpet, etc.) must be able to withstand more that the indicated values above.

Section 4 - Troubleshooting Information Service and Maintenance
Introduction
The following pages contain a table of Troubleshooting Information for locating and correcting most service trouble which can develop. Careful and accurate analysis of the systems listed in the table of Troubleshooting Information will localize the trouble more quickly than any other method. This manual cannot cover all possible troubles and deficiencies that may occur. If a specific trouble is not listed, isolate the major component in which the trouble oc­curs, isolate whether the problem is electrical or hydraulic, and then isolate and correct the specific problem.
The content of this section is separated into “probable cause” and “remedy.” The information preceded by a num­ber represents the “probable cause.” The following line, noted by a dash represents the “remedy” to the “probable cause” directly above it. See example below for clarification.

Section 5 - Procedures Service and Maintenance
General
The following information is provided to assist you in the use and application of servicing and maintenance procedures contained in this chapter.
Safety and Workmanship
Your safety, and that of others, is the first consideration when engaging in the maintenance of equipment. Always be conscious of weight. Never attempt to move heavy parts without the aid of a mechanical device. Do not allow heavy objects to rest in an unstable position. When raising a portion of the equipment, ensure that adequate support is provided.
Platform
5.1-1 OEM Controller Electronics Information
Flow Control
Single coil or solenoid for single direction. The coil has two connections; one is wired to the P.C. Board (A) terminal and the other is wired to (-), or the negative side of the supply voltage. Switches to control directional valves may be provided on the controller.
“Threshold” Adjustments
Adjust the initial current flow or duty cycle, affecting the function response or speed when the handle is first moved from the off position. Deflect the handle slowly to the position where the controller first turns on. Adjust the threshold trimpot screw to the point where the controlled function just starts to move, then turn the trimpot screw one, full turn in the counterclockwise direction. This adjustment should be done first.
“Maxout” Adjustments
Adjust the full stroke current or duty cycle affecting the maximum function response, or speed when the handle is deflected to its full travel. Fully deflect the handle, and adjust the maxout trimpot for maximum desired function response or speed. To obtain proportional resolution, it is important that the function starts to slow down as soon as the handle is moved back from the fully deflected position.
The ideal adjustment occurs when the function just begins to move when the handle is deflected, and the output increases until it reaches its maximum desired response or speed at the end of handle travel.
Adjustment Procedures
Adjustments are made by turning a trimpot adjustment screw. The trimpots are multi-turn, end-to-end devices. It may be necessary to turn the adjustment screw several turns to observe a change in output.
Clockwise (CW) adjustment of the trimpot increases the output.
Counter-clockwise (CCW) adjustment of the trimpot decreases the output.
Adjustments affect output current, voltage or percentage of duty cycle to the coil. The minimum and maximum output is preset at the factory. However, for optimum performa nce, they mus t be adjusted while the equipment is operating.
Although the following adjustments affect the current/ voltage or percentage of duty cycle, the best way to adjust the function is to observe the response or speed of the function. The following adjustments affect function response, or speed. There may be some interaction between adjustments, making it necessary to repeat the adjustment in order to achieve the desired response.

5.1-2 OEM Controller Troubleshooting
Problem
1. The function will not operate when the handle is moved. The LEDs do not light
A. Check that voltage is present at the positive
(+)input terminal.
B. Check that ground is connected to the
negative (-) terminal.
C. If there is an in-line fuse, check to see if it is
good.
D. Check the controller on/off switch and the
connectors. Voltage should be present at the (X) terminal when the controller is turned on.
E. Check that valve wiring is not shorted to
ground. The LEDs will not light.
F. Check that valve wiring is not open. The
LEDs will light, but the intensity will not vary.
G. Check trimpot settings. Fully “CCW” turns
output off, “CW” turns output fully on.
2. The function jumps or lurches when turned on.
A. P e r f o r m “ T h r e s h o ld ” a d ju st me nt
procedures.
3. The function reaches maximum speed before the handle is fully deflected,
A. Perform “Maxout” adjustment procedures.
4. The function speed remains constant regardless of the degree of handle deflection.
A. Perform “Maxout” adjustment procedures.
IRS Option
1. Function speed reacts too slowly or too quickly in relation to handle deflection.
A. Check “IRS” (Ramp) trimpot adjustment.
“CW ” inc r ea s e s ra m p ti m e, “ C CW ” decreases ramp time.
Integrated Ramp System (IRS)
Provides smooth function response ,when reacting to an abrupt change in handle deflection. “CW” rota­tion of the trimpot increases ramp time and slows the response time. “CCW” decreases ramp time and in­creases the response time. To increase the ramp time, turn the adjusting screw “CW” a few turns, then move the controller handle abruptly. Continue to adjust until a smooth response is observed. Most controllers have on/off contacts which remove power from the P.C. Board when the handle is returned to the off position. When the handle is abruptly returned to neutral, the output will not ramp down, and the function will stop.
Ramp Thru Off
The P.C. Board should be adjusted as outlined in the IRS adjustment procedure. If the handle is abruptly returned to neutral (OFF) the output will ramp down to off. Ramp time is factory set to 2 seconds, unless otherwise specified.
NOTE
Trimpots should be sealed with nail polish
or enamel based paint.
WARNING
Do not use RTV silicone.
