INTRODUCTION-MAINTENANCE SAFETY  \nPRECAUTIONS  \nA . GENERAL  \nThis section contains general safety precautions which must be observed during aerial platform maintenance. It is of utmost importance that maintenance personnel pay strict attention to these warnings and precautions to avoid possible injury to themselves or others, or damage to the equipment. A maintenance program must be followed to ensure machine is safe to operate.  \nMODIFICATION OR ALTERATION OF AN AERIAL WORK PLATFORM SHALL BE MADE ONLY WITH WRITTEN PERMISSION FROM THE MANUFACTURER.  \nThe specific precautions to be observed during maintenance are inserted at the appropriate point in the manual. These precautions are, for the most part, those that apply when servicing hydraulic and larger machine component parts.  \nYour 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.  \nSINCE THE MACHINE MANUFACTURER HAS NO DIRECT CONTROL OVER THE FIELD INSPECTION AND MAINTENANCE, SAFETY IN THIS AREA RESPONSIBILITY OF THE OWNER/OPERATOR.  \nB . HYDRAULIC SYSTEM SAFETY  \nIt should be noted that the machines hydraulic systems operate at extremely high potentially dangerous pressures. Every effort should be made to relieve any system pressure prior to disconnecting or removing any portion of the system.  \nC . MAINTENANCE  \nFAILURE TO COMPLY WITH SAFETY PRECAUTIONS LISTED IN THIS SECTION COULD RESULT IN MACHINE DAMAGE, PERSONNEL INJURY OR DEATH AND IS A SAFETY VIOLATION.  \n• WEAR APPROPRIATE PERSONAL PROTECTIVE EQUIPMENT WHEN WORKING ON MACHINE.  \n• ENSURE REPLACEMENT PARTS OR COMPONENTS ARE IDENTICAL OR EQUIVALENT TO ORIGINAL PARTS OR COMPONENTS.  \n• NO SMOKING IS MANDATORY. NEVER REFUEL DURING ELECTRICAL STORMS. ENSURE THAT FUEL CAP IS CLOSED AND SECURE AT ALL OTHER TIMES.  \n• REMOVE ALL RINGS, WATCHES AND JEWELRY WHEN PERFORMING ANY MAINTENANCE.  \n• DO NOT WEAR LONG HAIR UNRESTRAINED, OR LOOSE-FITTING CLOTHING AND NECKTIES WHICH ARE APT TO BECOME CAUGHT ON OR ENTANGLED IN EQUIPMENT.  \n• OBSERVE AND OBEY ALL WARNINGS AND CAUTIONS ON MACHINE AND IN SERVICE AND OPERATOR MANUAL.  \n• KEEP OIL, GREASE, WATER, ETC. WIPED FROM STANDING SURFACESAND HAND HOLDS.  \n• USE CAUTION WHEN CHECKING A HOT, PRESSURIZED COOLANT SYSTEM.  \n• NEVER WORK UNDER AN ELEVATED BOOM UNTIL BOOM HAS BEEN SAFELY RESTRAINED FROM ANY MOVEMENT BY BLOCKING OR OVERHEAD SLING, OR BOOM SAFETY PROP HAS BEEN ENGAGED.  \n• BEFORE MAKING ADJUSTMENTS, LUBRICATING OR PERFORMING ANY OTHER MAINTENANCE, SHUT OFF ALL POWER CONTROLS.  \n• BATTERY SHOULD ALWAYS BE DISCONNECTED DURING REPLACEMENT OF ELECTRICAL COMPONENTS.  \n• KEEP ALL SUPPORT EQUIPMENT AND ATTACHMENTS STOWEDIN THEIR PROPER PLACE.  \n• USE ONLY APPROVED, NON-FLAMMABLE CLEANING SOLVENTS.  \n3121180 – JLG Lift – A-1  \nREVISON LOG  \nOriginal Issue Revised  \nRevised  \nRevised  \nRevised  \nRevised  \nRevised  \nRevised  \nRevised  \n-January 24, 2003  \n-March 14, 2003  \n-August 26, 2005  \n-February 15, 2006  \n-March 14, 2007  \n-October 10, 2007  \n-December 22, 2010  \n-November 1, 2012  \n-December 3, 2012  \nA-2 – JLG Lift – 3121180  \nSECTION NO.
