SECTION 1 - SAFETY PRECAUTIONS

1.3 OPERATION

General

• The JLG MVL/MSP Model Lifts are electric self-propelled
machines with an aerial work platform mounted to an ele­vating aluminum mast mechanism. The personnel lift’s
intended purpose is to provide personnel access to areas
above ground level.
The MSP model lift is intended for stock picking purposes in
retail stores or warehouses to allow placing and removing

of stock from storage or display areas.

• Do not use the machine for any purpose other than posi­tioning personnel, their tools and equipment, or for hand
stock picking.

• Never operate a machine that is not working properly. If a
malfunction occurs, shut down the machine.

• Never slam a control switch or lever through neutral to an
opposite direction. Always return switch to neutral and
stop before moving the switch to the next function. Oper­ate controls with slow and even pressure.

• Do not allow personnel to tamper with or operate the
machine from the ground with personnel in the platform,
except in an emergency.

• Do not carry materials directly on platform railing unless
approved by JLG.

• Always ensure that power tools are properly stowed and
never left hanging by their cord from the platform work
area.

• Fully lower mast assembly and shut off all power before
leaving machine.

• When performing welding operations at elevation, precau­tions must be taken to protect all machine components
from contact with weld splatter or molten metal.

• Battery fluid is highly corrosive. Avoid contact with skin and
clothing at all times.

• Charge batteries on in a well ventilated area.

Trip and Fall Hazard

• JLG Industries, Inc. recommends that the operator in the
platform wear approved fall protection attached to an
authorized lanyard anchorage point. Reference “StockPick­ing Platform Operation” on page 28 for fall protection
requirements applicable to stockpicker platforms operated
with the rails in the open position. For further information
regarding fall protection requirements on JLG products,
contact JLG Industries, Inc.

3121230 – JLG Lift – 1-3

SECTION 1 - SAFETY PRECAUTIONS

• Before operating the machine, make sure all railing and
gates are fastened in their proper position.

• Keep both feet firmly positioned on the platform floor at all
times. Never use ladders, boxes, steps, planks, or similar
items on platform to provide additional reach.

• Never use the mast assembly to enter or leave the platform.

• Use extreme caution when entering or leaving platform.

Ensure that the mast assembly is fully lowered. Face the
machine when entering or leaving the platform. Always
maintain “three point contact” with the machine, using two
hands and one foot or two feet and one hand at all times
during entry and exit.

3121230 – JLG Lift – 3-1

3.2 MACHINE DESCRIPTION

The JLG MVL/MSP Model Lifts are electric self-propelled
machines with an aerial work platform mounted to an elevating
aluminum mast mechanism. The personnel lift’s intended pur­pose is to provide personnel access to areas above ground level.
The MSP model lift is intended for stock picking purposes in
retail stores or warehouses to allow placing and removing of

stock from storage or display areas.

The primary control station is located in the platform. From the
Platform Control Console the operator can drive the machine
and raise or lower the platform.

The controls of the programmable Ground Control Station are
to be used during machine power-up, machine maintenance or
in case of emergency should the operator in the platform be
unable to lower the platform.

Vibrations emitted by these machines are not hazardous to an
operator working in the platform.

The continuous A-Weighted sound pressure level at the work
platform is less than 70db (A).

SECTION 3 - MACHINE CONTROLS, INDICATORS AND OPERATION

3.3 MACHINE OPERATION

Getting Started

The following control conditions must be met before the
machine can be operated from either the Ground or Platform
Controls.

• The batteries contain enough voltage to operate the
machine.

• The Main Power Selector Switch on the Ground Control Sta­tion must be set for either Ground Control Mode or Plat­form Control Mode.

• Both Emergency Stop Switches, one on the Ground Control
Station the other on the Platform Control Console must be
in the RESET position.

• If equipped, the On/Off Key Switch on the Platform Console
must be set to the ON position.

3.4 BATTERY CHARGING

This machine is equipped with an AC voltage input/DC voltage
output battery charger. The charger automatically terminates
charging when the batteries reach full capacity.

NOTE: The platform drive function is disabled when the battery

charger is plugged into an AC receptacle.

LEAD ACID BATTERIES MAY GENERATE EXPLOSIVE HYDROGEN GAS DURING
NORMAL OPERATION. KEEP SPARKS, FLAMES, AND SMOKING MATERIALS
AWAY FROM BATTERIES. PROVIDE ADEQUATE VENTILATION DURING CHARG­ING. NEVER CHARGE A FROZEN BATTERY. STUDY ALL BATTERY MANUFAC­TURERS’ SPECIFIC PRECAUTIONS SUCH AS RECOMMENDED RATES OF CHARGE

3121230 – JLG Lift – 3-3

SECTION 3 - MACHINE CONTROLS, INDICATORS AND OPERATION

To Charge Batteries

1. Park machine in a well ventilated area near an AC volt­age electrical outlet.

2. Always use a
grounded AC outlet.
Connect charger to
an outlet that has
been properly
installed and
grounded in accor­dance with all local
codes and ordi­nances. A grounded
outlet is required to
reduce risk of elec­tric shock – do not
use ground adapt­ers or modify plug.
When using an
extension cord,
avoid excessive volt­age drops by using a
grounded 3-wire 12
AWG cord.

Battery Charging Status Indicators

The battery charging status indicators are located just above the
Charger AC input receptacle on the center cover section at the
rear of the machine. (See Figure 3-1. on page 3-8)

1. When plugged in the charger will automatically turn
on and run through a short LED indicator self-test (all
LED’s will flash in an up-down sequence for two sec­onds).

2. The YELLOW ‘CHARGING’ LED will turn on and a trickle
current will be applied until a minimum voltage is
reached.

CHARGING

YELLOW (MIDDLE) LED ON
Charge Incomplete

Once a minimum battery voltage of 2 volts per cell is
detected, the charger will enter the bulk charging con­stant-current stage and the YELLOW ‘CHARGING’ LED
will remain on. The length of charge time will vary by
how large and how depleted the battery pack is, the
input voltage (the higher, the better), and ambient
temperatures (the lower, the better). If the input AC
voltage is low (below 104VAC), then the charging

3-4 – JLG Lift – 3121230

SECTION 3 - MACHINE CONTROLS, INDICATORS AND OPERATION

power will be reduced to avoid high input currents. If
the ambient temperature is too high, then the charg­ing power will also be reduced to maintain a maxi­mum internal temperature.

3. When the GREEN ‘CHARGED’ LED turns on, the batter­ies are completely charged.

CHARGE COMPLETE

GREEN (TOP) LED ON
100% Complete

The charger may now be unplugged from AC power

(always pull on plug and not cord to reduce risk of dam­age to the cord). If left plugged in, the charger will

automatically restart a complete charge cycle if the
battery pack voltage drops below a minimum voltage
or 30 days has elapsed.

4. If a fault occurred anytime during charging, a fault
indication is given by flashing the RED ‘FAULT’ LED
with a code corresponding to the error.

CHARGING PROBLEM

RED (BOTTOM) LED ON

See Flash Codes following

There are several possible conditions that generate
errors. Some errors are serious and require human
intervention to first resolve the problem and then to
reset the charger by interrupting AC power for at least
10 seconds. Others may be simply transient and will
automatically recover when the fault condition is elim­inated. To indicate which error occurred, the RED
‘FAULT’ LED will flash a number of times, pause, and
then repeat.

[1 FLASH] Battery Voltage High: auto-recover. Indi­cates a high battery pack voltage.

[2 FLASH] Battery Voltage Low: auto-recover. Indi­cates either a battery pack failure, battery pack is not
connected to charger, or battery volts per cell is less
than 0.5 VDC. Check the battery pack and battery pack
connections.

3121230 – JLG Lift – 3-5

SECTION 3 - MACHINE CONTROLS, INDICATORS AND OPERATION

[3 FLASH] Charge Timeout: Indicates the battery did
not charge within the allowed time. This could occur if
the battery is of a larger capacity than the algorithm is
intended for. It can also occur if the battery pack is
damaged, old, or in poor condition. In unusual cases it
could mean charger output is reduced due to high
ambient temperature.

[4 FLASH] Check Battery: Indicates the battery pack
could not be trickle charged up to the minimum 2
volts per cell level required for the charge to be
started. This may also indicate that one or more cells in
the battery pack are shorted or damaged.

[5 FLASH] Over-Temperature: auto-recover. Indicates
charger has shutdown due to high internal tempera­ture which typically indicates there is not sufficient air­flow for cooling – see step 1 of Installation
Instructions. Charger will restart and charge to com­pletion if temperature is within accepted limits.

[6 FLASH] QuikQ Fault: Indicates that the batteries will
not accept charge current, or an internal fault has
been detected in the charger. This fault will nearly
always be set within the first 30 seconds of operation.
Once it has been determined that the batteries and
connections are not faulty and Fault 6 is again dis­played after interrupting AC power for at least 10 sec­onds, the charger must be brought to a qualified
service depot.

3.11 TRANSPORTING, LIFTING AND TIE DOWN PROCEDURES

General

All MVL and MSP Model Personnel Lifts may be transported to a
work site using the following methods:

• Driving the machine around on its base wheels if travel sur­face area permits.

• Loaded, IN AN UPRIGHT POSITION ONLY onto a heavy-duty
vehicle with the payload capacity capable of supporting
the full weight of the machine (Check machine gross weights
in the Operating Spec Chart at the beginning of this Section).

• Moved with a fork-lift truck using the fork-lift pockets in the
base frame.

Truck Transport

DO NOT TRANSPORT THE MACHINE IN A HORIZONTAL POSITION DUE TO
LEAKAGE OF BATTERY ACID FROM THE BATTERIES OR HYDRAULIC FLUID
FROM THE HYDRAULIC RESERVOIR.

The machine may be winched onto a tilted roll-back truck bed
(see important note following) which has been rolled back to
ground level. Disengage the brakes and always winch (pull)

from the mast (rear) end of the machine, using the rear tie-down
loop attached to the base frame.

DO NOT ATTEMPT TO DRIVE MACHINE ONTO, OFF OF, OR PUSH MACHINE
ONTO A TILTED ROLL-BACK TRUCK BED.

THE MVL AND MSP MACHINES POWER MODULE COULD SUSTAIN SERIOUS DAMAGE
WHEN THE UNIT IS PUSHED, OR TOWED AT SPEEDS GREATER THAN 2 MPH.

WHEN TOWING OR WINCHING, THE MACHINE’S BRAKES MUST BE DISENGAGED.

RE-ENGAGE THE BRAKES ONCE MACHINE IS IN PLACE WITH TRUCK BED LEVEL AND
READY FOR TIE DOWN.

TIE DOWN LOOPS ARE PROVIDED ON BOTH ENDS OF THE BASE FRAME TO SECURE

3.13 OBSTRUCTION SENSING SYSTEM ­(MSP OPTION)

System Description

The Obstruction Sensing System (OSS) is designed to detect the
presence of obstructions within a predetermined detection
zone beneath the platform, when lowering the platform from
an elevated position.

NOTE: The OSS only operates normally when the Ground Control

Module - Power Selector Switch is set to PLATFORM CON­TROL MODE.
When the Power Selector Switch is set to GROUND CON­TROL MODE the OSS will detect an obstruction but will
not stop platform downward movement or sound the
horn. However, the OSS Control Module LED will flash if a
sensor detects the presence of an object.

Operation

NOTE: See Figure 3-10. for the location of the OSS Electronic

module.

When the machine is powered on a RED LED located on the OSS
electronics module will illuminate. During platform lowering, if
no obstructions have entered the detection zone beneath the
platform, the platform will lower normally.

If an obstruction is detected within the detection zone beneath
the platform, the platform will;

• Stop Lowering

• The RED LED on the electronics module will flash

• The horn will sound three short blasts

If an obstruction is detected, have the obstruction cleared by
someone on the ground or carefully drive the lift until clear of
the obstruction. Reset the OSS by pressing the horn button on
the platform control once and continue machine operation.
Should the OSS falsely detect an obstruction, the system can be
overridden by pressing and holding the horn button while
operating the platform lowering controls.

ALWAYS CHECK THE AREA UNDER THE PLATFORM IS CLEAR OF OBSTRUC­TIONS BEFORE LOWERING THE PLATFORM.

OSS Pre-Start Inspection

(See Figure 3-10.)

From ground controls, raise platform approximately 5'-6'. The
RED LED on the electronic module will be illuminated when
power is applied. If an obstruction, such as a pad of paper is
placed under any of the transducer sensor arrays, the RED LED
will flash and remain flashing while the obstruction is present
and stop flashing 3 seconds after the obstruction is removed.
Check the operation of each transducer sensor array by placing
an object individually under each sensor array (within approxi-
mately 6"-12") and checking if the RED LED starts to "flash", and
stops flashing 3 seconds after the obstruction is removed. Also,
inspect the transducer arrays and electronic module for physical
damage, loose wires, loose mounting hardware, etc.

3.15 STOCK-PICKER HANGER ACCESSORY

SECTION 3 - MACHINE CONTROLS, INDICATORS AND OPERATION

NOTE: The stock-picker hanger accessory is available only on the

JLG MSP model and is not authorized for use with any
other JLG lift. This hanger accessory is intended for use in
placing or retrieving stock items such as bicycles, ladders,
etc., on racks or shelves above ground level. Use for any
other purpose is not authorized by JLG.

The hanger accessory is a pivoting arm mounted to the MSP
platform rail. The hanger accessory can be mounted to either
side of the platform individually, or two can be mounted, one on
each side of the platform. Each individual hanger has a maxi­mum load capacity of 100 lb. (45kg).

The hanger arm can be pivoted out of the way parallel with the
platform side rails when not in use, (the stowed position). The
hanger arm is pinned into position at 90 degrees to the platform
side rails when in use, (the carry position).

Pre-Start Inspection

Prior to use of the hanger accessory, check the following;

• Hanger arm mounting is secure to the platform railing, no
missing or damaged fasteners.

• The hanger arm lock pin is in place and secure.

THE COMBINED WEIGHT OF PERSONNEL, MATERIALS, EQUIPMENT PLUS ANY
LOAD ON THE HANGER ARM ACCESSORY MUST NOT EXCEED THE MAXIMUM
LOAD CAPACITY OF THE PLATFORM.

Loading and Transporting an Item using the Hanger Accessory

Use the following steps as a guide when loading and transport­ing an object with the hanger accessory arm.

1. Keep the hanger arm in the stowed position when not
in use.

2. When ready to use, pull the lock pin from the stowed
position hole and swing the hanger arm into the carry
position. Place pin in the carry position hole locking
the hanger arm in place.

3. Load the object onto the hanger arm and use the
hanger arm strap to secure the object during trans­port.

SECTION 5 - GENERAL SPECIFICATIONS AND OPERATOR MAINTENANCE

5.3 OPERATOR MAINTENANCE

Battery

The OEM batteries are AGM sealed (VRLA) type so the electro­lyte level cannot be serviced, however the battery terminals
should be checked periodically for corrosion and tightness.
The batteries are located under the top rear hood covers on
each side of the Ground Control Station.

Tires and Wheels

Tire Wear and Damage

Inspect tires periodically for wear or damage. Tires with worn
edges or distorted profiles require replacement. Tires with sig­nificant damage in the tread area or side wall, require immedi­ate evaluation before replacing the machine into service.

Wheel and Tire Replacement

Replacement wheels must have the same diameter and pro­file as the original. Replacement tires must be the same size
and rating as the tire being replaced.

Wheel Installation

It is extremely important to apply and maintain proper wheel
mounting torque.

WHEEL LUG NUTS MUST BE INSTALLED AND MAINTAINED AT THE
PROPER TORQUE TO PREVENT LOOSE WHEELS, BROKEN LUG NUTS,
AND POSSIBLE SEPARATION OF WHEEL FROM THE AXLE. BE SURE TO
USE ONLY THE LUG NUTS MATCHED TO THE CONE ANGLE OF THE
WHEEL.

3121230 – JLG Lift – 5-9

SECTION 5 - GENERAL SPECIFICATIONS AND OPERATOR MAINTENANCE

Tighten the lug nuts to the proper torque to prevent wheels
from coming loose. Use a torque wrench to tighten the fas­teners. If you do not have a torque wrench, tighten the fasten­ers with a lug wrench, then immediately have a service
garage or dealer tighten the lug nuts to the proper torque.
Over-tightening will result in breaking the lug nuts or perma­nently deforming the mounting holes in the wheels. The
proper procedure for attaching wheels is as follows:

1. Start all lug nuts by hand to prevent cross threading.
DO NOT use a lubricant on threads or nuts.

2. Tighten lug nuts in the following sequence.

Figure 5-1. Wheel Lug Nut Tightening Sequence

3.The tightening of the lug nuts should be done in stages.
Following the recommended sequence, tighten lug nuts
per wheel torque.

4. Wheel lug nuts should be torqued after the first 50
hours of operation and after each wheel removal.
Check torque every 3 months or 150 hours of opera­tion.

+50° F to +210° F (+10° C to +99° C) 20W-20

Hydraulic oils must have anti-wear qualities at least to API Ser­vice Classification GL-3, and sufficient chemical stability for
mobile hydraulic system service. JLG Industries, recommends
Mobilfluid 424 hydraulic oil, which has an SAE viscosity of
10W-30 and a viscosity index of 152.

For cold weather applications, i.e. when temperatures remain
consistently below +20°F (–7°C) JLG recommends using Mobil
DTE 13 hydraulic oil.

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 Industries for proper recommendations.

5.5 DRIVE MOTOR BRUSH WEAR - WARNING INDICATION

The machines drive motors include brush wear sensors that
activate a warning indicating the drive motor brushes will
require replacment soon. This warning protects the drive
motors from damage due to extreme brush wear.

When the brush wear warning is activated the Ground Con­trol Station LCD screen will indicate a fault code of 6, also the
hourmeter is set to countdown 25 hours of (DRIVE) operation
remaining.

The Platform Control LEDs will indicate this warning with 8
flashing LEDs and an intermittent beep.

NOTE: Only the drive function when used will affect the hour

meter count down once the warning has been activated.
The machine will operate normally until the last 10 sec­onds of the 25 hour countdown.

During the last 10 seconds of the 25 hour (DRIVE) countdown
the machine will only drive in creep/turtle drive mode and
platform lift up will be disabled. At this point cycling power
on/off will only repeat the final 10 second mode cycle.

The machine will not operate normally until the drive motor
brushes are replaced (repositioning the brush warning sensors),
and the Ground Control Station is programmed to reset the
Brush Wear - Warning Timer per the Service and Maintenance
Manual.
