Section 1 - About Your Aerial Platform
1. About Your Aerial Platform
This section provides general information about your aerial platform. It describes the major components, standard and optional features, safety reminders and precautions.
1.1 Major Assemblies
The aerial platform consists of three major assemblies: the platform, the lifting mechanism and the base. An operator’s control box is mounted on one of the platform guardrails. Auxiliary and emergency controls are located at the base.
1.2 Platform
The platform is constructed of a tubular support frame, a skid-resistant “diamond plate” deck surface and 40” to 43-1/2" (1016 - 1100mm) hinged guardrails with 6" (152mm) toe boards and mid-rails. The platform can be entered from the rear through an entry chain or optional
spring-returned gate with latch. The platform is also equipped with an extension platform.
1.3 Operator’s Control Box
1.5 Lifting Mechanism
The lifting mechanism is constructed of formed steel or tube sections making up a scissor-type assembly. The scissor assembly is raised and lowered by single-acting hydraulic lift cylinders with holding valves. A two-section pump, driven by an electric motor, provides hydraulic power to the lift cylinders.
1.6 Maintenance Support
A maintenance support is located inside the lifting mechanism. When properly positioned, it can support the scissor assembly and empty platform. The maintenance support MUST be used during inspection and maintenance or when repairs are being performed within the lifting mechanism.
1.7 Base
The base is a rigid, one-piece weldment which supports two side cabinets or two swing out trays.
One tray contains the hydraulic and electrical components. The other tray contains battery charger and eight (8) 6 volt batteries.

3 LEDs blink once simultaneously: Output connection error. Check the battery and charger connection. The output may not be connected to the batteries or the connections to the batteries may have corroded or loosened. The output may be shorted due to improper connection to the batteries or pinched wires. The output may be connected in reverse polarity to the batteries. The charger is not damaged by any of these problems.
3 LEDs blink twice simultaneously: The charger is indicating that the AC voltage is too low or too high. Check the AC input voltage.
3 LEDs blink three times simultaneously: Charger is overheated. No action required. When the charger cools, charging will re-start automatically. Check and correct for dirt or other debris on charger that may be reducing cooling.
Visually and manually inspect to verify the DC output
wires and terminals are in good working condition
before each use.
4. The charger will start automatically within four to six seconds. The charger will start even with severely discharged batteries (down to 1V terminal voltage). Once charging starts, the LEDs indicate the charging progress.

Section 2 - Operation Battery Maintenance
Batteries do not fully charge.
If the batteries are charged overnight, make sure the AC supply is not being switched off at night with other building items. Check battery condition and for dead cells or reduced capacity. Replace charger only if other problems are not found.
The AC line circuit breaker or fuse is blown.
A defective circuit breaker or fuse, an overloaded cir­cuit, or a charger problem can cause this condition. Try connecting the charger to a different AC outlet (on a different circuit) in the building. If the AC supply checks good, the charger should be replaced.
EE-Rated Machines
Warning
Do not charge batteries in hazardous area !
The EE-rating of a machine does not include the
charging of batteries.
1. Move the aerial platform to an area designated
for battery charging. Refer to NFPA 505 for charging set-up. NFPA 505 is a publication of the National Fire Protection Association, Inc., Batterymarch Park, Quincy, MA 02269 (USA).
2. Connect battery charger DC plug into the battery
plug at the rear of the base.
3. Charge batteries. Refer to Section 2.9-2 for
battery charging operation. When charge cycle is completed, disconnect charger plug from battery tray.

** LCP - Locally Concentrated Pressure is a measure of how hard the machine presses on the areas
in direct contact with the floor. The floor covering (tile, carpet, etc.) must be able to withstand more
that the indicated values above. OUP - Overall Uniform Pressure is a measure of the average load the machine imparts on the whole surface directly underneath it. The structure of the operating surface (beams, etc.) must be able to withstand more than the indicated values above.
NOTE:
The LCP or OUP that an individual surface can withstand varies from structure to structure and is generally determined by the engineer or architect for that particular structure.
