Service and Maintenance Manual Model 150HAX P/N-3120679 February 15, 2012 SECTION A . INTRODUCTION-MAINTENANCE SAFETY PRECAUTIONS A GENERAL This section contains the general safety precautions which must be observed during maintenance of the aerial platform. 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 that the machine is safe to operate. MODIFICATION OR ALTERATION OF AN AERIAL WORK PLATFORM SHALL BE MADE ONLY WITH WRITTEN PERMISSION FROM THE MANUFACTURER. The 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. 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. SINCE THE MACHINE MANUFACTURER HAS NO DIRECT CONTROL OVER THE FIELD INSPECTION AND MAINTENANCE, SAFETY IN THIS AREA RESPONSIBILITY OF THE OWNER/OPERATOR. B HYDRAULIC SYSTEM SAFETY It 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. Relieve system pressure by cycling the applicable control several times with the engine stopped and ignition on, to direct any line pressure back into the reservoir. Pressure feed lines to system components can then be disconnected with minimal fluid loss. C MAINTENANCE FAILURE TO COMPLY WITH SAFETY PRECAUTIONS LISTED IN THIS SECTION COULD RESULT IN MACHINE DAMAGE, PERSONNEL INJURY OR DEATH AND IS A SAFETY VIOLATION. • ENSURE REPLACEMENT PARTS OR COMPONENTS ARE IDENTICAL OR EQUIVALENT TO ORIGINAL PARTS OR COMPONENTS. • NO SMOKING IS MANDATORY. NEVER REFUEL DURING ELECTRICAL STORMS. ENSURE THAT FUEL CAP IS CLOSED AND SECURE AT ALL OTHER TIMES. • REMOVE ALL RINGS, WATCHES AND JEWELRY WHEN PERFORMING ANY MAINTENANCE. • DO NOT WEAR LONG HAIR UNRESTRAINED, OR LOOSE-FITTING CLOTHING AND NECKTIES WHICH ARE APT TO BECOME CAUGHT ON OR ENTANGLED IN EQUIPMENT. • OBSERVE AND OBEY ALL WARNINGS AND CAUTIONS ON MACHINE AND IN SERVICEMANUAL. • KEEP OIL, GREASE, WATER, ETC. WIPED FROM STANDING SURFACES AND HAND HOLDS. • USE CAUTION WHEN CHECKING A HOT, PRESSURIZED COOLANT SYSTEM. • 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. • BEFORE MAKING ADJUSTMENTS, LUBRICATING OR PERFORMING ANY OTHER MAINTENANCE, SHUT OFF ALL POWER CONTROLS. • BATTERY SHOULD ALWAYS BE DISCONNECTEDDURING REPLACEMENT OF ELECTRICAL COMPONENTS. • KEEP ALL SUPPORT EQUIPMENT AND ATTACHMENTS STOWED IN THEIR PROPER PLACE. • USE ONLY APPROVED, NONFLAMMABLE CLEANING SOLVENTS. 3120679 – JLG Lift – A-1 REVISON LOG Original Issue Revised Revised Revised -May 15, 1992 -January 2, 2001 -February 4, 2010 -February 15, 2012 A-2 – JLG Lift – 3120679 TABLE OF CONTENTS SUBJECT-SECTION, PARAGRAPH PAGE NO.

FAQs

What safety precautions are emphasized in Section A before performing maintenance?

Section A requires strict attention to safety precautions to avoid injury to personnel or others and to prevent equipment damage. It also mandates following a maintenance program to keep the machine safe to operate.

How should hydraulic system pressure be relieved before disconnecting components?

Relieve pressure by cycling the applicable control several times with the engine stopped and ignition on to route line pressure back into the reservoir. Then pressure feed lines can be disconnected with minimal fluid loss.

What maintenance conduct requirements apply to personnel and parts?

Use replacement parts or components identical or equivalent to original parts. Follow safety rules such as no smoking, not refueling during electrical storms, removing rings/watch/jewelry during maintenance, avoiding loose clothing and long unrestrained hair, and shutting off all power controls before adjustments or maintenance.
