SECTION 1. SAFETY PRECAUTIONS
1.1 GENERAL
This section prescribes the proper and safe practices for
major areas of machine usage which have been divided
into three basic categories: Driving, Operation, and Main-
tenance. In order to promote proper usage of the
machine, it is mandatory that a daily routine be estab-
lished based on the instructions given in this manual. A
maintenance program, using the information provided in
the Service and Maintenance Manual, must also be estab-
lished by a qualified person and must be followed to
ensure that the machine is safe to operate.
The owner/user/operator/lessor/lessee of the machine
should not accept operating responsibility until this man-
ual has been read and operation of the machine, under
the supervision of an experienced and qualified operator,
has been completed. These sections contain the respon-
sibilities of the owner, users, operators, lessors and les-
sees concerning safety, training, inspection, maintenance,
application and operation. If there is a question on appli-
cation and or operation, JLG Industries should be con-
sulted
MODIFICATION OR ALTERATION OF AN AERIAL PLATFORM
SHALL BE MADE ONLY WITH PRIOR WRITTEN PERMISSION OF
THE MANUFACTURER.
1.2 DRIVING/TOWING/CARRYING
Before driving the machine the user must be familiar with
the drive, steer and stopping characteristics. This is espe-
cially important when driving in close quarters.
The user should be familiar with the driving surface before
driving. The surface should be firm and level and grades
should not exceed the allowable grade for the machine,
25%.
NOTE: Remember that the key to safe and proper usage is
common sense and its careful application.
It is not recommended that this machine be towed, except
in the event of a machine malfunction, a total machine
power failure, or for loading on a truck. Refer to Section 6
for emergency towing procedures.
FAILURE TO COMPLY WITH SAFETY PRECAUTIONS LISTED IN
THIS SECTION AND ON MACHINE MAY RESULT IN MACHINE
DAMAGE, PERSONNEL INJURY OR DEATH AND IS A SAFETY
VIOLATION.
Carrying or loading the unit should be accomplished
using a forklift vehicle of suitable capacity with the forks
being positioned correctly at the indicated areas on the
machine frame. Refer to Section 4 for lifting information.

1.8 MAINTENANCE
This section contains the general safety precautions
which must be observed during maintenance of the aerial
work platform. It is of utmost importance that maintenance
personnel pay strict attention to these warnings and pre-
cautions to avoid possible injury to themselves or others
or damage to the equipment. A maintenance program
must be established by a qualified person and must be
followed to ensure that the machine is safe to operate.
MODIFICATION OF THE MACHINE WITHOUT CERTIFICATION BY
A RESPONSIBLE AUTHORITY THAT THE MACHINE IS AT LEAST
AS SAFE AS ORIGINALLY MANUFACTURED IS A SAFETY VIOLA-
TION.
The specific precautions to be observed during machine
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 equip-
ment, ensure that adequate support is provided.
• ALWAYS DISCONNECT BATTERIES WHEN REPLAC-
ING ELECTRICAL COMPONENTS.
• REMOVE RINGS, WATCHES AND JEWELRY WHEN
PERFORMING ANY MAINTENANCE.
• DO NOT WEAR LOOSE FITTING CLOTHING OR LONG
HAIR UNRESTRAINED, WHICH IS APT TO BECOME
CAUGHT ON, OR ENTANGLED IN EQUIPMENT.
• USE ONLY CLEAN APPROVED NONFLAMMABLE
CLEANING SOLVENTS.
• SHUT OFF ALL POWER CONTROLS BEFORE MAK-
ING ADJUSTMENTS, LUBRICATING OR PERFORM-
ING ANY OTHER MAINTENANCE.
• NEVER WORK UNDER AN ELEVATED PLATFORM
UNTIL IT HAS BEEN RESTRAINED FROM MOVEMENT
WITH SAFETY PROPS, BLOCKING OR OVERHEAD
SLING.
• NEVER ALTER, REMOVE OR SUBSTITUTE ANY
ITEMS SUCH AS COUNTERWEIGHTS, SOLID TIRES,
BATTERIES, ETC. WHICH WOULD REDUCE THE
OVERALL WEIGHT OR BASE STABILITY OF THE
MACHINE.

SECTION 2. PREPARATION AND INSPECTION
2.1 GENERAL
This section provides the necessary information needed
by those personnel that are responsible to place the
machine in operation readiness, and lists checks that are
performed prior to use of the machine. It is important that
the information contained in this section be read and
understood before any attempt is made to operate the
machine. Ensure that all the necessary inspections have
been completed successfully before placing the machine
into service. These procedures will aid in obtaining maxi-
mum service life and safe operation.
SINCE THE MACHINE MANUFACTURER HAS NO DIRECT CON-
TROL OVER THE FIELD INSPECTION AND MAINTENANCE,
SAFETY IS THE RESPONSIBILITY OF THE OWNER/OPERATOR.
2.2 PREPARATION FOR USE
1. Before a new machine is put into operation it must
be carefully inspected for any evidence of damage
resulting from shipment and inspected periodically
thereafter, as outlined in the Delivery and Periodic
Inspection. The unit should be thoroughly checked
for hydraulic leaks during initial start-up and run. A
check of all components should be made to assure
their security.
2. All preparation necessary to place the machine in
operation readiness status are the responsibility of
management personnel. Preparation requires good
common sense, (i.e. lift works smoothly and brakes
operate properly), coupled with a series of visual
inspections. The mandatory requirements are given
in the Daily Walk Around Inspection.
3. It should be assured that the items appearing in the
Delivery and Periodic Inspection and Functional
Check are complied with prior to putting the
machine into service.
2.3 DELIVERY AND PERIODIC INSPECTION
NOTE: This machine requires periodic safety and mainte-
nance inspections by a JLG Dealer.
The following checklist provides a systematic inspection
to assist in detecting defective, damaged, or improperly
installed parts. The checklist denotes the items to be
inspected and conditions to examine.
Periodic inspection shall be performed monthly or more
often when required by environment, severity, and fre-
quency of usage.
This inspection checklist is also applicable and must be
followed for all machines that have been in storage or for
all machines that will be exposed to harsh or changing cli-
mates.

2.4 DAILY WALK-AROUND INSPECTION
It is the users responsibility to inspect the machine before
the start of each workday. It is recommended that each
user inspect the machine before operation, even if the
machine has already been put into service under another
user. This Daily Walk-Around Inspection is the preferred
method of inspection.
These checks are also to be performed after maintenance
has been performed on the machine.
In addition to the Daily-Walk Around Inspection be sure to
include the following as part of the daily inspection:
Overall Cleanliness
Check all standing surfaces for hydraulic oil spillage and
foreign objects. Ensure overall cleanliness.
Placards
Keep all information and operating placards clean and
unobstructed. Cover when spray painting or shot blasting
to protect legibility. Uncover prior to machine operation
Operators and Safety and Service and
Maintenance Manual
Ensure that a copy of this manual is enclosed in the man-
ual storage holder.
Machine Log
Ensure a machine operating record or log is kept, check
to see that it is current and that no entries have been left
uncleared, leaving machine in an unsafe condition for
operation.
Daily Lubrication
For those items pointed out in the Daily Walk - Around
Inspection requiring daily lubrication, refer to the Lubrica-
tion Chart for specific requirements.
2.5 DAILY FUNCTIONAL CHECK
TO AVOID INJURY DO NOT OPERATE A MACHINE UNTIL ALL
MALFUNCTIONS HAVE BEEN CORRECTED. USE OF A MALFUNC-
TIONING MACHINE IS A SAFETY VIOLATION.
A functional check of all systems should be performed,
once the walk-around inspection is complete, in an area
free of overhead and ground level obstructions. First,
using the ground controls, check all functions controlled
by the ground controls. Next, using the platform controls,
check all functions controlled by the platform controls.
NOTE: On new machines, those recently overhauled, or
after changing hydraulic oil, operate all systems a
minimum of two complete cycles and recheck oil
level in reservoir.
1. Check Enable Switch for proper operation. Switch
must be pressed before activating any functions.
TO AVOID SERIOUS INJURY, DO NOT OPERATE MACHINE IF ANY
CONTROL LEVERS OR TOGGLE SWITCHES CONTROLLING
PLATFORM MOVEMENTS DO NOT RETURN TO THE OFF POSI-
TION WHEN RELEASED.
2. Raise and lower platform several times. Check for
smooth elevation and lowering. Check that High
Drive cut-out as platform begins to raise.
NOTE: Perform checks from ground controls first, then from
platform controls.
3. Drive forward and reverse, check for proper opera-
tion.
4. Check that drive brakes hold when machine is
driven up a hill, not to exceed rated gradeability, and
stopped.
5. Steer left and right. Check for proper operation.
6. Check hydraulic oil reservoir level marks. Refer to
Lubrication Chart.
7. Holding the Ground/Platform select switch to
Ground. Platform controls should not operate.
8. Place Ground/Platform select switch to off. Platform/
Ground controls should not operate.
2.6 TORQUE REQUIREMENTS
The Torque Chart consists of standard torque values
based on bolt diameter and grade, also specifying dry,
wet and loctite torque values in accordance with recom-
mended shop practices. This chart is provided as an aid

SECTION 2 - PREPARATION AND INSPECTION
3120880 – JLG Sizzor – 2-3
to the operator in the event he/she notices a condition that
requires prompt attention during the walk-around inspec-
tion or during operation until the proper service personnel
can be notified. The Service and Maintenance section pro-
vides specific torque values and periodic maintenance
procedures with a listing of individual components. Utiliz-
ing this torque chart in conjunction with preventive mainte-
nance section will enhance safety, reliability and
performance of the machine.
2.7 BATTERY MAINTENANCE AND
CHARGING
TO AVOID INJURY FROM AN EXPLOSION, DO NOT SMOKE OR
ALLOW SPARKS OR A FLAME NEAR BATTERY DURING SERVIC-
ING.
Battery Maintenance, Quarterly
1. Open battery compartment cover to allow access to
battery terminals and vent caps.
WHEN ADDING WATER TO BATTERIES, ADD WATER UNTIL ELEC-
TROLYTE COVERS PLATES. DO NOT CHARGE BATTERIES
UNLESS ELECTROLYTE COVERS PLATES.
NOTE: When adding distilled water to batteries, non-metallic
containers and/or funnels must be used.
To avoid electrolyte overflow, add distilled water to
batteries after charging.
When adding water to the battery, fill only to level
indicated.
2. Remove all vent caps and inspect electrolyte level of
each cell. Electrolyte level should be to the ring
approximately one inch from top of battery. Fill bat-
teries with distilled water only. Replace and secure
all vent caps.
3. (Remove battery cables from each battery post one
at a time, negative first. Clean cables with acid neu-
tralizing solution (e.g. baking soda and water or
ammonia) and wire brush. Replace cables and/or
cable clamp bolts as required.
4. Clean battery post with wire brush then re-connect
cable to post. Coat non-contact surfaces with no-ox-
id “A” compound, mineral grease or petroleum jelly.
5. When all cables and terminal posts have been
cleaned, ensure all cables are properly positioned
and do not get pinched. Close battery compartment
cover.
6. Start hydraulic system and ensure that it functions
properly.
Battery Charging, Daily
NOTE: To avoid excessive battery charging time, do not
allow batteries to become completely discharged.
To avoid electrolyte overflow, add distilled water to
batteries after charging.
When adding water to the battery, fill only to level
indicated.
1. Charge batteries at the end of each work day, or
when machine performance is significantly reduced
due to batteries becoming discharged.
2. Charge batteries in accordance with the following
procedure:
a. Position the Platform/Ground Select Switch to
the off position.
b. Open battery compartment, and battery charger
compartment covers.
WHEN BATTERY CHARGER IS TO BE USED, CHARGING HAR-
NESS MUST BE PLUGGED INTO A GROUNDED 110 VOLT RECEP-
TACLE. IF RECEPTACLE IS NOT GROUNDED AND A
MALFUNCTION SHOULD OCCUR, THE MACHINE COULD CAUSE
SERIOUS ELECTRICAL SHOCK.
c. Remove charging harness cable and connect to
a 220 volt receptacle.
d. Allow batteries to charge until ammeter on
charger, if equipped, is reading zero (0). Normal
charging time is 8-10 hours.
NOTE: When batteries are completely charged, disconnect
charging harness cable from receptacle. Store
charging harness cable.
e. Ensure battery cables are positioned and are not
pinched. Close and secure all compartment
doors.
3. The battery packs on each side of the frame are
designed to be easily removed so that a machine
can have two sets of them in order to keep the
machine functioning longer. Disconnect the cable
quick connects, and remove the two clevis pins on
top of the frame. Now, using the forklift pockets
under the packs, have a forklift move them to a
place where they can be recharged. The new battery
packs can be installed by reversing the above pro-
cedure.
NOTE: Battery packs are interchangeable.
