INTRODUCTION - MAINTENANCE SAFETY PRECAUTIONS

3120855 – 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 TORQUE REQUIREMENTS

Torque nut to 169 -203 Nm (dry), then add extra torque to

line up the slot with the hole in the shaft to install the cotter

pin.

NOTE: When maintenance becomes necessary or a fas-

tener has loosened, to determine proper torque

value, refer to Figure 1-2., Torque Chart.

1.5 LUBRICATION

Hydraulic Oil

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 of 10W-30

and a viscosity index of 152. When temperatures

remain consistently below -20 F (-7 C), JLG recom-

mends the use of MobilDTE13M hydraulic oil.

NOTE: Aside from JLG recommendations, it is not advisable

to mix oils of different brands or types, as they may

not contain the same required additives or be of

comparable viscosities. If use of hydraulic oil other

than Mobilfluid 424 is desired, contact JLG Indus-

tries for proper recommendations.

1.6 SERIAL NUMBER LOCATIONS

For machine identification, a serial number plate is affixed

to the machine. On 2032E2/2632E2/2646E2 and 3246E2

the plate is located on the front, center of the machine

frame, on 1932E2 it is located above the right rear tire. The

serial number will also be stamped on the front center of

the machine frame.

1.7 LIMIT SWITCHES

The machines are equipped with the following limit

switches:

Tilt Alarm - Illuminates a light on the platform and sounds

an alarm when the machine is elevated and out of level in

any direction 2° or more.

High Drive Cut-Out - High drive speed is cut out when the

platform is raised above the preset height per model as

follows.

1932E2 - 2.6 m

2032E2 - 2.1 m

2632E2 (Australian Only) - 2.9 m

2632E2/2646E2 - 2.6 m
