SAFETY RULES

Personal SafetyAny person working on or around a machine mustbe aware of all known safety hazards. Personalsafety and the continued safe operation of themachine should be your top priority.

Read each procedure thoroughly. Thismanual and the decals on the machine,use signal words to identify the following:

Safety alert symbol—used to alertpersonnel to potential personalinjury hazards. Obey all safetymessages that follow this symbolto avoid possible injury or death.

Red—used to indicate thepresence of an imminentlyhazardous situation which, if notavoided, will result in death orserious injury.

Orange—used to indicate thepresence of a potentiallyhazardous situation which, if notavoided, could result in death orserious injury.

Yellow with safety alert symbol—used to indicate the presence of apotentially hazardous situationwhich, if not avoided, may causeminor or moderate injury.

Yellow without safety alertsymbol—used to indicate thepresence of a potentiallyhazardous situation which, if notavoided, may result in propertydamage.

Green—used to indicate operationor maintenance information.

Be sure to wear protective eye wear andother protective clothing if the situationwarrants it.

Be aware of potential crushing hazardssuch as moving parts, free swinging orunsecured components when lifting or

placing loads. Always wear approved steel-toedshoes.

Workplace SafetyBe sure to keep sparks, flames andlighted tobacco away from flammable andcombustible materials like battery gases

and engine fuels. Always have an approved fireextinguisher within easy reach.

Be sure that all tools and working areasare properly maintained and ready foruse. Keep work surfaces clean and free of

debris that could get into machine components andcause damage.

Be sure that your workshop or work areais properly ventilated and well lit.

Be sure any forklift, overhead crane orother lifting or supporting device is fullycapable of supporting and stabilizing the

weight to be lifted. Use only chains or straps thatare in good condition and of ample capacity.

Be sure that fasteners intended for onetime use (i.e., cotter pins and self-lockingnuts) are not reused. These componentsmay fail if they are used a second time.

Be sure to properly dispose of old oil or otherfluids. Use an approved container. Please beenvironmentally safe .

Platform Controls

The platform controls, used to activate machinefunctions from the platform or while standing on theground, contain a printed circuit board, joystick,decal membrane pad, buttons and/or toggleswitches, and LEDs. All of these components arereplaceable though only the potentiometer-equipped joystick, used before serial numberGS6803-42382, is serviceable.

On models before serial number GS6803-42382,the platform controls are also used to tune theperformance of the machine.

The function speed parameters in the ElectronicControl Module are easily adjusted by moving thejoystick, pressing a button or activating a toggleswitch in a specific order when the ECM is in theprogramming mode (PS showing in the diagnosticdisplay window).

For further information or assistance, consult theGenie Industries Service Department.

Hydraulic Pump

8-1Hydraulic Pump

The hydraulic pump is a 2-section, gear-typepump. Pump number 1 is the pump section whichis closer to the engine and pump number 2 is thepump section that is farther from the engine. Eachsection of the pump has its own relief valve in thefunction manifold.


How to Test the Hydraulic Pump1 Tag, disconnect and plug the high pressure

hydraulic hoses from both sections of thehydraulic pump.


2 Connect a 0 to 5000 psi / 0 to 350 bar pressuregauge to the high pressure port on each sectionof the pump.

3 Gasoline/LPG models: Disconnect the ignitioncoil wire from the center of the ignition coil.

Diesel models: Hold the manual fuel shutofflever clockwise in the closed position.


5 Observe the pressure gauge while cranking theengine. Immediately stop if the pressurereaches or exceeds 3000 psi / 206 bar in eitherone of the gauges.

Result: If both of the pressure gauges read3000 psi / 206 bar, immediately stop. The pumpis good.

Result: If pressure fails to reach3000 psi / 206 bar in one or both sections of thepump, one of the pump sections or the pumpcoupling is bad and will need to be serviced orreplaced.

6 Remove the pressure gauges and connect thehydraulic hoses.

How to Test a Coil DiodeGenie incorporates spike suppressing diodes inmany valve coils. Properly functioning coil diodesprotect the electrical circuit by suppressing voltagespikes. Voltage spikes naturally occur within afunction circuit following the interruption ofelectrical current to a coil. Faulty diodes can fail toprotect the electrical system, resulting in a trippedcircuit breaker or component damage.


1 Test the coil for resistance. See 9-3, How toTest a Coil.

2 Connect a 10 resistor to the negative terminalof a known good 9V DC battery. Connect theother end of the resistor to a terminal on thecoil.

The battery should read 9V DC ormore when measured across theterminals.
