General

• 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

3.1 GENERAL

THE MANUFACTURER HAS NO DIRECT CONTROL OVER MACHINE APPLI­CATION AND OPERATION. THE USER AND OPERATOR ARE RESPONSIBLE
FOR CONFORMING WITH GOOD SAFETY PRACTICES.

This section provides the necessary information needed to
understand control function and operation.

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.

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

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 3­wire 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 constant­current 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 power will be reduced to avoid high input currents.
If the ambient temperature is too high, then the charging
