OPERATION INSTRUCTIONS CART-23, -24
o Ensure that all employees involved in the operation of this cart understand and follow these instructions!
The standard model CART is suitable for use in most industrial and commercial locations. It is intended to be used to transport and lift stable, evenly-distributed, non-hazardous loads and containers with rigid sides having a size or footprint approximately the same size as the platform.
Loading:
The load rating, in pounds, is shown on the machine dataplate located on the left corner of the push handle end of the platform. It indicates the net capacity of the CART with a static load that is centered and evenly distributed on the platform.
Warning: The platform’s rollers are not captured. Therefore, do not overhang any load at the hinged end of the platform – that could cause the roller end of the platform to tip up and dump the load. For applications involving side or end edge loading, consult the factory.
Note: The addition of any ancillary equipment to the cart by third parties must be taken into account when determining the maximum working load to be placed on the platform.
Warning: Do not exceed the cart’s load ratings. Injury to personnel or permanent damage to the cart could result from exceeding the listed capacity.
Operation:
Inspect the perimeter pinch point guards’ operation daily (DC units). Warning: Keep all personnel clear of the machine when it is in operation. Be certain no part of any pers on or
object is under any part of the platform before lowering the unit. Caution: Always carefully watch the platform and any load on it when it is in operation.
Do not exceed a rate of two feet per second when transporting a load with the cart.
o The standard manually-powered CART is furnished with a two-speed foot pump. Under empty or low load
conditions, the pump pushes a higher volume of fluid to the cylinder and thus lifts the platform with fewer foot strokes. With a moderate to full load, the pump will automatically reduce its output in order to generate the required hydraulic pressure.
To lift the platform, simply repeatedly press the foot pump’s foot treadle. To lower the platform, press the small lever at the left corner of the pump with your toe. The unit will hold its position when the lowering lever is released.
o The standard DC-powered CART is furnished with a constant-pressure (dead-man style) pushbutton control.
Pressing the “UP” pushbutton will turn on the power unit to raise the platform. The platform will raise only while the control is pressed. Upon releasing the control, the platform will stop and hold its position.
Pressing the “DOWN” pushbutton will energize the lowering valve to allow the platform to descend by gravity (the motor does not run). Again, releasing the control will stop the platform movement, and the unit will hold its position.
Caution: Never use the cart if any damage or unusual noise is observed, if it is in need of repair s, or if it seems to be malfunctioning. Notify your supervisor or maintenance personnel if you notice anything out of the ordinary.
On DC-powered units, attempting to raise the lift when the battery is low will cause the motor relay protection to prevent the motor’s operation. Adequate battery voltage is indicated by a green LED on the motor relay. See the next page for more notes regarding operation of battery-powered units.
Ensure that all safety and warning labels stay in place and are legible. Refer to the labels page in this manual.

ADDITIONAL INSTRUCTIONS FOR BATTERY-POWERED UNITS
Note: If this product has the 24V powered traction-drive option, consult that option’s information for more
specific details regarding the batteries and battery charger.
Warning!
! Working with or near lead acid batteries is dangerous. Batteries contain sulfuric acid and produce explosive
gases. A battery explosion could result in loss of eyesight or serious burns.
! Do not smoke or allow a spark or flame near batteries. Charge batteries in locations that are clean, dry, and
well ventilated. Do not lay tools or anything metallic on top of any battery. All repairs to a battery must be made by experienced and qualified personnel.
! When working with batteries, remove personal items such as rings, bracelets, necklaces, and watches.
Batteries can produce enough energy to weld jewelry to metal, causing a severe burn.
! Always have fresh water and soap nearby in case battery acid contacts skin, clothing, or eyes. ! Operating the battery with a low battery voltage can cause premature motor contact failure. ! Do not expose the lift or the charger to rain or adverse conditions. ! Replace defective cords or wires immediately. ! Check the battery’s water level frequently.
Battery Charger Operating Instructions
Never operate the charger with either of the cables coiled. Operating a battery charger with the cord either
coiled or wrapped around itself could cause the cord to overheat, melt, and cause a short-circuit or a fire.
Connection: the ribbed wire of the charger’s output cord must be connected to the battery’s negative (-) terminal. The non-ribbed wire (with words printed on it) must be connected to the battery’s positive (+) terminal.
When properly connected, the charger will indicate the status of its output:
Flashing green LED – the charger is not seeing a good connection to the battery. Solid yellow LED – the charger is providing charging current to the battery. Solid green LED – the charger is maintaining a fully charged battery.
Plug the charger into a standard 115V receptacle. If an extension cord must be used, keep it as short as
possible.
Caution: Remember to unplug the charger before moving the equipment. Failure to do so could cause
damage to cords, receptacles, and other equipment.
The battery charger can be left connected to the battery indefinitely without risk of harming the battery.
Troubleshooting:
If the unit does not operate, check all of the wiring connections to make sure they’re both mechanically and
electrically sound – specifically at the battery, the motor, and at any location a wire is connected to the chassis. Also, make sure the quick-connect plug on the end of the pendant control cord is plugged in correctly (if applicable).
A fully charged lead acid battery in good condition at room temperature should read 12.65 volts. At 11.9
volts it is considered to be fully discharged and in need of charging. When checking battery voltage, wait at least 1/2 hour after the charger has been turned off before checking the batter y ’s voltage.
If the batteries don’t seem to be taking a charge, check the charger’s 115V supply circuit and the charger’s output with a voltmeter. If all check okay, confirm the battery’s state of charge using a hydrometer or a voltmeter.

ROUTINE MAINTENANCE & SAFETY CHECKS, CART-23, -24
o Warning: Care should be taken to identify all potential hazards and comply with applicable safety
procedures before beginning work.
o Warning: Remove any load, raise the platform, and install maintenance props before beginning any
inspections or work on the unit.
o Only qualified individuals trained to understand mechanical devices and their associated electrical and
hydraulic circuits should attempt troubleshooting and repair of this equipment
(A) Inspect daily for:
1.) Frayed wires (DC units).
2.) Oil leaks.
3.) Pinched or chafed hoses.
4.) Damage or structural deformation to the structural members, the cylinder brackets, etc.
5.) Unusual noise or binding, or evidence thereof.
6.) Proper functioning of all limit switches, including those on the perimeter pinch point guard (DC units).
(B) Inspect monthly for:
1.) The oil level. Oil should be 1” to 1½” below the reservoir’s fill hole with the lift in the fully lowered position.
2.) Oil leaks.
3.) Worn or damaged electrical wires (DC units) or hydraulic hoses.
4.) Pivot point wear.
5.) Rollers’ looseness and wear.
6.) Integrity of the retaining hardware on all rollers and on all pivot point pins.
7.) Looseness, wear, or damage to the casters’ bearings, mounting hardware, or su rface material.
8.) Proper water level in the battery (DC units only.)
9.) Unusual noises.
10.) All the information, safety, and warning labels being in place and in good condition.
11.) The need to clean off dirt and debris.
(C) Yearly inspection
The oil should be changed if the oil darkens, becomes gritty, or turns a milky color (indicating the presence of water). Replace with an anti-wear hydraulic oil with a viscosity grade of 150 SUS at 100°F, (ISO 32 at 40°C). Ex: AW 32 or HO 150 hydraulic oil, or a non-synthetic transmission fluid. You may use a synthetic transmission fluid if you flush the system with the synthetic fluid before filling the reservoir.
