INTRODUCTION - MAINTENANCE SAFETY PRECAUTIONS

3120826 – JLG Sizzor – a

SECTION A. INTRODUCTION - MAINTENANCE SAFETY

PRECAUTIONS

A.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 main-

tenance personnel pay strict attention to these warn-

ings 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 OF THE MACHINE WITHOUT CERTIFI-

CATION BY A RESPONSIBLE AUTHORITY THAT THE

MACHINE IS AT LEAST AS SAFE AS ORIGINALLY

MANUFACTURED, IS A SAFETY VIOLATION.

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 consider-

ation when engaging in the maintenance of equip-

ment. 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 pro-

vided.

SINCE THE MACHINE MANUFACTURER HAS NO

DIRECT CONTROL OVER THE FIELD INSPECTION

AND MAINTENANCE, SAFETY IN THIS AREA RESPON-

SIBILITY OF THE OWNER/OPERATOR.

A.B HYDRAULIC SYSTEM SAFETY

It should be noted that the machines hydraulic sys-

tems operate at extremely high potentially danger-

ous 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.

A.C MAINTENANCE

FAILURE TO COMPLY WITH SAFETY PRECAUTIONS

LISTED IN THIS SECTION MAY RESULT IN MACHINE

DAMAGE, PERSONNEL INJURY OR DEATH AND IS A

SAFETY VIOLATION.

• NO SMOKING IS MANDATORY. NEVER REFUEL DUR-

ING 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 CAU-

TIONS ON MACHINE AND IN SERVICE MANUAL.

• KEEP OIL, GREASE, WATER, ETC. WIPED FROM

STANDING SURFACES AND HAND HOLDS.

• USE CAUTION WHEN CHECKING A HOT, PRESSUR-

IZED 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 DISCONNECTED DUR-

ING REPLACEMENT OF ELECTRICAL COMPONENTS.

• KEEP ALL SUPPORT EQUIPMENT AND ATTACHMENTS

STOWED IN THEIR PROPER PLACE.

• USE ONLY APPROVED, NONFLAMMABLE CLEANING

SOLVENTS.

1.4 LUBRICATION

NOTE: Hydraulic oils must have anti-wear qualities at least

to API Service Classification GL-3, and sufficient

chemical stability for mobile hydraulic system ser-

vice. JLG Industries recommends Mobilfluid 424

hydraulic oil, which has an SAE viscosity index of

152.

NOTE: When temperatures remain consistently below -7° C

( 20° F ), JLG Industries recommends the use of

Mobil DTE11.

Some machines may be specially equipped with Mobil

EAL224H biodegradable and non-toxic hydraulic oil. This

oil is vegetable oil based and possesses the same anti-

wear and rust protection characteristics as mineral oils,

but will not adversely affect ground water or the environ-

ment when spilled or leaked in small amounts. Mobil

EAL224H has a viscosity of 34 cST at 40°C and a viscosity

index of 213. The operating range of this oil is -18°C to

+83°C
