DAMAGED EQUIPMENT POLICY
Safety Statement
At Bil-Jax, we are dedicated to the safety of all users of our products. Therefore,
all Bil-Jax lifts are designed, manufactured, and tested to comply with current
applicable Federal OSHA and ANSI codes and regulations.
Damage Policy
There may be occasions when a Bil-Jax lift is involved in an incident that results
in structural damage to the lift. This can seriously compromise the ability of the lift
to perform in a safe manner. Therefore, whenever a Bil-Jax lift is damaged
structurally or when there is the possibility of structural damage (this damage
may be internal and is not always visible to the naked eye), Bil-Jax requires that
the lift be returned to our facility at 125 Taylor Parkway, Archbold, Ohio, for
reconditioning. If you have any questions concerning what constitutes structural
damage, please call the Bil-Jax Service Department at 800-537-0540.
Damage Repair Notice
There may be occasions when a Bil-Jax lift is involved in an incident resulting in non-
structural damage. When this occurs and repairs are made by the owner or area
distributor, please notify Bil-Jax of these non-maintenance repairs and request a repair
form to be filled out and returned to Bil-Jax.

2INTRODUCTION
The ESP 19 hydraulic lift is designed and manufactured for use as a warehouse
stocking and order picking vehicle. Its guard rail design permits the operator to
ride on the platform with the load, while transferring parts to and from multiple
overhead storage locations. The maximum platform load is limited to 450 lbs.
All ESP 19 operations are powered by a 24-Volt DC battery package. A 40-amp
battery charger and plug-in receptacle are included in the system for recharging
the batteries at the end of each work period. A charge level indicator displays the
battery charge status.
The platform lift function is hydraulic, including a hydraulic cylinder, reservoir, and
pump. The hydraulic pump motor is driven by a 24-Volt DC electric motor.
Elevation is by a 1-3/4 inch linear-displacement hydraulic cylinder and four
telescoping mast sections. The lower mast section is raised by hydraulic cylinder.
The upper mast sections are raised mechanically by connecting sets of chains
and sheaves (pulleys). The lift platform rises four inches for each inch of
hydraulic cylinder extension.
Other electrically powered functions include a two-wheel drive transaxle for floor
travel and pushbutton steering. The maximum travel speed is enabled only when
the lift platform is down. When the platform is raised, the travel speed is limited.
The transaxle includes an electric brake that locks the drive wheels whenever
forward or reverse travel is halted. The electric brake is normally applied; the
brake disengages when forward or reverse travel is enabled with the joystick. In
case of a loss of battery power, a manual free wheel lever can be used to
disengage the electric brake, allowing the lift vehicle to be towed.
Floor travel and platform lift functions are controlled from an upper control box
located on the lift platform. Floor travel is by joystick control with pushbutton
steering. Lift functions are by pushbutton control. Platform lift can also be
controlled from a lower control box mounted on the vehicle base. An electronic
level sensor disables all lift and travel functions except platform lowering if the lift
vehicle base is more than one degree out of level. While out of level, travel can
be resumed after the lift platform is fully lowered.
With equipment power on or off, turning an emergency lowering valve knob
lowers the lift platform at a controlled, safe speed. The lowering valve knob is
visible and readily accessible from floor level.
Proper lift vehicle operation and safety are assured by performing the scheduled
inspection and maintenance procedures set forth in this manual. The risk of
platform free-fall is eliminated by proper maintenance of the chains, sheaves and
sheave pins, a properly installed flow restrictor valve, and a clean mast. The
restrictor valve (non-adjustable) fixes the maximum rate of platform descent to
approximately 0.6 feet per second, whether the platform is empty or fully loaded.
With the restrictor valve properly installed, a hydraulic hose failure will result in
the same maximum rate of descent.
Carefully read and understand all of the safety instructions in Section 1 and
all operating instructions in Section 3 of this manual before operating the lift
vehicle

vehicle.
Position the lift vehicle at the work area. Make sure
the vehicle is on a firm and level surface and that
there are no potential hazards such as speed
bumps, open floor drains, potholes, overhead
obstructions or electrically charged conductors. Do
not operate the lift vehicle if such hazards exist in
the immediate area.
NOTE: The lift vehicle is equipped with a level
sensor. When the vehicle is on a slope greater
than 1 degree, the level sensor disables all
functions other than platform lowering and
sounds an alarm beeper. Once the platform is
lowered, floor travel is again enabled to allow
travel to a level area.
During floor travel and lift operations, the alarm
beeper should sound. If the alarm beeper does not
work properly, do not operate the lift vehicle.
During lift platform descent, the amber caution light
should blink on and off. If the caution light does not
blink on and off, do not use the lift vehicle.
If any equipment motion continues after the
pushbutton, joystick, or selector switch is released,
press the EMERGENCY STOP pushbutton, Figure 3-2.
All equipment motion should stop immediately.
At the end of each workday and whenever a low
battery alarm sounds, transport the lift vehicle to the
recharge site and plug in the charge cord. Verify that
the ON-CHARGING indicator lights up on the battery
charger.
NOTE: For more information on battery charging
operations, refer to the battery charging
procedure in paragraph 4-4.
To shut down the equipment, turn the UPPER
CONTROL/OFF/LOWER CONTROL key switch and
