ALL occupants must wear an approved fall restraint properly attached to designated platform anchorage point. Attach only one fall restraint to each anchorage point.
NEVER exceed maximum platform load of 500 lbs. (225 kg) and two (2) occupants. NEVER exceed 45 lbs. (200 N) of side force per occupant.
DISTRIBUTE all platform loads evenly on the platform.
NEVER operate the machine without first surveying the work area for surface hazards such as holes, drop-offs, bumps, curbs, or debris; and avoiding them.
OPERATE machine only on surfaces capable of supporting wheel loads. NEVER elevate the machine when wind speeds exceed 28 mph (12.5 m/sec.).
IN CASE OF EMERGENCY push emergency stop button to cut power to all machine functions. ALWAYS close and secure gate after entering platform.
NEVER exit or enter platform while elevated.
NEVER use ladders, scaffolding, or other items to gain height; work only from the platform floor. NEVER climb down elevating assembly while platform is elevated.
INSPECT the machine thoroughly for cracked welds, loose or missing hardware, hydraulic leaks, loose wire connections, and damaged cables or hoses before using.
VERIFY that all labels are in place and legible before using. Refer to page 10 & 11 for label identification. NEVER use a machine that is damaged, not functioning properly, or has damaged or missing labels.
IF ALARM SOUNDS while boom is elevated, STOP, carefully retract boom and lower platform without rotating. Move machine to a firm, level surface.
NEVER attach overhanging loads or use boom as a crane.
NEVER alter operating or safety systems without manufacturers written consent.
NEVER charge battery near sparks or open flame. Charging batteries emit explosive hydrogen gas.
NEVER replace any component or part with anything other than original UpRight replacement parts without the manufacturer's written consent.
NEVER tow the machine. Transport by truck or trailer only.

Instructions Operating and Rules Safety
Introduction
This manual covers the operation of electric powered models of the AB-46 Articulated Boom. This manual must be stored on the machine at all times.
Pre-Operation and Safety
Inspection
Carefully read, understand and follow all safety rules, labels, and operating instructions, then perform the following steps each day before use.
Perform a complete visual inspection of the entire unit prior to operating. Check the following areas for discrepancies:
1.Open panels and check hydraulic components / hoses for damage or leaks. Check electrical components / wiring for damage or loose connections.
2.Inspect chassis, axles, hubs, and steering linkage for damage, deformation, buckled paint, loose or missing hardware, and cracked welds.
3.Check tires for damage, punctures, and inflation; tire pressure must be 75 psi.
4.Check all hoses / cables for wear.
5.Inspect elevating assembly for damage, deformation, buckled paint, loose or missing hardware, and cracked welds.
6.Inspect platform and guardrails for damage, deformation, buckled paint, loose or missing hardware, and cracked welds. Insure that gate operates freely and latches securely.
7.Check Hydraulic fluid level with platform fully lowered.
8.Check battery fluid level (see battery maintenance, page 8).
DO NOT use a machine that is damaged or malfunctioning. Tag and remove the unit from service until it is repaired.
SYSTEM FUNCTION INSPECTION
Note: Refer to figures 1 and 2 for chassis and platform control locations.
1.Before performing the following tests, check area around machine and overhead for obstructions, holes, drop-offs, and debris.
2.Turn chassis key switch to chassis, and turn on (rotate clockwise) emergency stop switches at the chassis control panel and at the platform control panel.
3.Push in the chassis emergency stop button and operate any function switch at the chassis control panel, function should NOT activate. Repeat for platform emergency stop button, operating chassis controls. Return both emergency stop switches to the on position.
4.Operate each function switch to raise / lower, extend / retract, rotate left / right, each section of the elevating assembly and observe the operation of the machine. All functions should operate through full cycle smoothly.
5.Turn chassis key switch to platform.
6.Mount the platform, close and latch the gate, and attach approved fall restraint to designated platform anchorage point. Attach only one fall restraint to each point.
7.Without depressing the foot switch, move the drive control handle, machine should not function.
8.Depress the foot switch and move the drive control handle forward and reverse. Observe that proportional functions operate smoothly, and that brakes apply quickly after control is released.
9.While depressing foot switch, operate steer switch to left and right. Observe that steering wheels turn properly.
10.While depressing foot switch, turn function speed control knob to desired setting, and operate boom controls. Observe that boom operates smoothly, and that upper boom, jib, turret rotation, platform level, and platform rotation controls operate proportionally in conjunction with function speed control knob. Observe that platform maintains level when boom is elevated.
11.With the upper boom elevated one foot, operate drive control handle. Observe that drive speed is limited to creep (1/2 foot [.15m] per second). Lower upper boom to stowed position.
12.Press the service horn button. Observe that horn is audible.

Figure 2: Platform Controls
Operation
Before operating work platform insure that:
Pre-operation and safety inspection has been completed, and any discrepancies have been corrected.
The operator has been thoroughly trained on the operation of the machine.
The work area is clear of all obstructions, holes, drop-offs, or persons in the route of travel.
The surface is capable of supporting wheel loads.
Refer to figures one and two for control locations.
Emergency Stop
At any time during operation, press the emergency stop button to stop all functions in an emergency.
Service Horn
At any time during operation, press the service horn button to sound an audible warning if necessary.
Always wear an approved fall restraint properly attached to designated platform anchorage point when driving or elevating the machine (see figure 3).
Attach only one fall restraint to each anchorage point.

Driving
With Boom Lowered
1.Turn chassis key switch to platform, and turn on (turn clockwise) the chassis emergency stop switch.
2.Mount the platform, close and latch the gate.
3.Attach approved fall restraint to designated platform anchorage point. Attach only one fall restraint to each point.
4.Check that the area around and above the work platform is clear of obstructions, holes, drop-offs, persons in the route of travel, and the surface is capable of supporting wheel loads.
5.Depress the foot switch and move the drive control handle forward to travel forward and reverse to travel in the reverse direction.
Note: When the boom is rotated to the front of the chassis (steering wheels aft) directions of travel and steering will be reversed. Observe the color coded arrows on the control panel near the drive control handle, and on the chassis. They will indicate the direction of travel when the drive control handle is moved.
With Boom Elevated
Travel with boom elevated is restricted to firm level surfaces only.
When driving elevated, the machine will travel at creep speed (1/2 foot [.15 m] per second).
Steering
1.While depressing the foot switch, push the steering switch (located on top of the control handle) to the left to turn left, and right to turn right.
Note: Steering is not self centering. Wheels must be returned to the straight ahead position by operating the steering switch.
POSITIONING THE PLATFORM
Positioning the platform as close as possible to the work area requires some planning. First, you must survey the work site to find a suitable place to park the machine. This must be a firm level area as close as possible to the work area. Take into consideration all obstructions on the ground and overhead and avoid them.
Once you have moved the machine to a firm level surface as near as possible to the work area, follow the instructions on page five to position the platform.
Always, before operating any function, check the area around and overhead for any obstructions or electrical conductors.
Multifunction Controls
The UpRight AB-46 employs the use of multifunction controls. This means that riser or boom extension will function at full speed while simultaneously operating upper boom, jib, turret, or rotating the platform.
The turret may be rotated while driving if necessary to make turns in tight areas. All other boom functions will not operate while driving.
Lower Control Operation
All boom functions will operate at fixed speed.
1.Turn chassis keyswitch to chassis controls.
2.Operate boom control switches to position the platform.
