PERATION
:
Instruct other persons in the area to stand at a safe distance while the deck raises or lowers. Be
certain no part of any person, clothing, or object is under any part of the platform before lowering the deck.
The Modular Power Unit (MPU) controls the scissors lift table portion of the cart by means of a constant pressure
(dead-man style) pushbutton controller.
•
To raise the deck, press the “UP” button. The button activates the motor and the deck will rise. However, the
deck will rise only
as long as the control is pressed
. When the button is released, the deck will stop moving
and will maintain its elevated position.
•
To lower the deck, press and hold the “DOWN” button. In response, the lowering valve energizes and gravity
causes the deck to descend. The motor does not run during descent. When the button is released, the deck
stops descending and holds its current position.
DO NOT use the cart if:
1. You notice any damage or hear unusual noise(s) while raising or lowering the deck;
2. The cart requires maintenance or repairs; or
3. The cart malfunctions in any way.
Tag the cart “Out of Service” and immediately notify your supervisor or maintenance personnel if you notice
anything out of the ordinary.
The motor relay protection feature activates when the battery charge is low; it prevents the motor from running
and thus the deck cannot be raised. Adequate battery voltage is indicated by a green LED on the motor relay. If
the deck does not rise when you press the UP button, recharge the battery according to the instructions given in
the section titled, “Battery Charger Operation”.
The cart is manually propelled. The MPU only powers the scissors lift table; it does not propel the cart. After
loading the cart and properly securing the load to the deck, push the cart to the desired location. Do not exceed a
rate of two feet per second when transporting a load with the cart.

Working with or near lead acid batteries is dangerous. ONLY work on or replace the battery if
authorized and trained to do so.
•
Batteries contain sulfuric acid and produce explosive gases. A battery explosion could result in loss of
eyesight or serious burns. ALWAYS wear eye and face protection as well as personal protective clothing as
required by OSHA regulations (29 CFR.1910 Subpart I and 29 CFR.1926.441) whenever you work on or with
the battery.
•
DO NOT smoke in the vicinity of the battery, and do not expose the battery to sparks or flames. ONLY
charge the battery in locations that are clean, dry, and well ventilated.
•
DO NOT operate the charger if either charger cable is coiled. Charging the battery while the cord is either
coiled or wrapped around itself could cause a short circuit or fire, and the cord might overheat and/or melt.
•
DO NOT lay tools or anything metallic on top of the battery.
•
To reduce the possibility of being severely burned, remove personal items like rings, bracelets, necklaces,
and watches. Batteries produce enough energy to weld jewelry to metal.
•
ALWAYS have fresh water and soap nearby in case battery acid contacts skin, clothing, or eyes.
•
Replace defective cords or wires immediately.
•
Frequently check the water level of the battery.
Fully uncoil both of the charger cables.
Connect the charger cables to the battery in the following order:
1. The ribbed wire (of the charger output cord) connects to the negative (-) terminal on the battery.
2. The plain wire (with text printed on it) connects to the positive (+) terminal on the battery.
Plug the charger into a standard 115V receptacle. If an extension cord is necessary, use the shortest, thickest
cord available.
When properly connected, LED’s on the charger indicate the status of battery recharging:
•
Flashing green LED – the charger detects a poor connection to the battery.
•
Solid yellow LED – the charger is charging the battery.
•
Solid green LED – the battery is fully charged. The charger can remain connected to the battery
indefinitely without harming the battery
