If the machine doesn’t starts the first step to take is to check the mandatory conditions:
- Turn ON the Master Switch;
- FNR lever to Neutral Position;
- Stationary brake switch ON;
- Emergency switch UP;
- Turn ON the ignition Switch.
o Did the machine start?
Yes (Problem solved).
No (Continue inspection).
If the machine is not reaching maximum speed, either going forward, reverse or both, and
there is no error code in the display, the cause shall be in the motors solenoids circuit.
The solenoids can be found attached to the drive motors, behind the rear wheels. There are
two solenoids in each side. These actuators are responsible for the motors swash plates control.
• The operator must employ safe working practices and observe all related local work safety
requirements and regulations, also the technical documentation (such as operators manual and
safety instructions) has to be followed.
• Maintenance must only be performed by authorised, trained and specialised personnel.
• Before maintenance, repair work, adjustment or any other non-routine checks, stop the
equipment, switch off the voltage, press the emergency button and depressurise the
compressor/ equipment. In addition, the power insolating switch must be opened and locked or
removed.
• Use only the correct tools for maintenance and repair work.
• All maintenance work shall only be undertaken when the machine has cooled down.
• A warning sign bearing a legend such as ‘Work in progress; do not start’ shall be attached to the
starting equipment.
• Before removing any pressurized component, effectively isolate the machine from all sources of
pressure and relieve the entire system of pressure.
• Scrupulously observe cleanliness during maintenance and repair. Keep dirt away by covering the
parts and exposed openings with a clean cloth, paper or tape.
• Make sure that no tools, loose parts or rags are left in or on the machine.
• All regulating and safety devices shall be maintained with due care to ensure that they function
properly. They may not be put out of action.
• Always wear the following personal protective equipment: Work clothing, safety shoes, safety
goggles, ear protection and safety gloves when there is a cutting risk or a risk for a heat injury.
