Foreword
To OWNERS, USERS, and OPERATORS:
The safe and efficient operation of a lift truck requires
skill and alertness on the part of the operator. To develop
the skill required, the operator must:
•Receive training, pursuant to OSHA 1910.178(1) dated
12/98, in the proper operation of THIS lift truck.
•Understand the capabilities and limitations of the lift
truck.
•Become familiar with the construction of the lift truck and
see that it is maintained in good condition.
•Read and properly understand the warnings, instruc-
tions, and operating procedures in this manual.
In addition, a qualified person, experienced in lift truck
operation, must guide a new operator through several driv-
ing and load handling operations before the new operator
attempts to operate the lift truck alone.
It is the responsibility of the employer to make sure that the
operator can see, hear, and has the physical and mental
ability to operate the equipment safely.
Various laws and regulations require the employer to train
lift truck operators. These laws and regulations include:
•Occupational Safety and Health Act (OSHA) (USA)
•Canada Material Handling Regulations
NOTE: A comprehensive operator training program is avail-
able from Yale Company. For further details, contact your
dealer for Yale Company lift trucks.

Model Description
General
The Yale MPB045VG lift trucks are pedestrian-operated lift
trucks with lifting capacities of 2,041 kg (4,500 lb).
These lift trucks are electric power vehicles. A battery pro-
vides the electric power for travel and hoist functions. The
battery is located on the fork frame and moves with the
forks. The battery/battery compartment also acts as a load
backrest and helps to steady the load.
The control handle or delivery handle is used to select the
various functions of the truck, including: steering, selecta-
ble performance modes, braking, direction and speed con-
trol, lifting, lowering, and horn. See Figure 1 and Figure 2.
This lift truck can be stopped by one of three methods of
braking:
1. Plugging
2. Neutral Braking
3. Returning the control handle or delivery handle to the
brake ON position
A detailed operating instruction is provided in the Operat-
ing Procedures section of this manual.
The operator has a choice of three performance modes
that are selectable through the control handle or delivery
handle. The mode selection is made at startup or key ON.
Performance parameters that vary are:
1. Acceleration
2. Deceleration (neutral braking)
3. Top travel speed
A detailed operating instruction is provided in the Operat-
ing Procedures section of this manual.
The Operating Manual is stored in the container on the
drive compartment. This is a permanent reference and
must be available for use at all times.

Nameplate
WARNING
Any change to the lift truck or its equipment can
change the lifting capacity. If the Nameplate does not
show the maximum capacity, or if the lift truck equip-
ment, including the battery, does not match that shown
on the Nameplate, then the lift truck must NOT be oper-
ated.
The Nameplate for the lift truck is found on the frame. The
capacity shown is for a lift truck equipped as shown on the
nameplate. The capacity is specified in kilograms (kg). The
capacity is the maximum load that the lift truck can handle
for the load condition shown on the Nameplate. See Fig-
ure 3.
The maximum capacity for the lift truck must be shown on
the Nameplate. If the lift truck Nameplate already has a
capacity for special load handling equipment, it will be lis-
ted. Make sure the Nameplate data is complete and fully
understood before operating the lift truck.
The lift truck serial number code is on the Nameplate. The
serial number code is also stamped on the lift truck frame.
Figure 3. Nameplate and Label
Safety Labels
Safety labels are installed on the lift truck to give informa-
tion about possible hazards. It is important that all safety
labels are installed on the lift truck and can be read. See
