WARNING

All personnel shall carefully read, understand and follow all safety rules, operating

instructions and the Scaffold Industry Association's MANUAL OF RESPONSIBILITIES

before performing maintenance on or operating any UpRight aerial work platform.

SAFETY RULES

Safety Rules and Operating Instructions

NEVER elevate

platform unless all
four (4) outriggers
have been properly
installed. All
outrigger screwjack
pads must be in solid
contact with a firm
surface before the
platform is elevated.

NEVER operate the machine
within ten feet of power lines.

THIS MACHINE IS NOT
INSULATED.

NEVER use ladders, planks or other devices to increase the height of the platform.
NEVER attach overhanging loads to the platform or increase the platform size.
NEVER elevate the platform if it contains more than one person or more than the rated load (see specifica-

tions on back page).

LOOK up, down and around for overhead obstructions and electrical conductors.
NEVER change operating or safety systems.
NEVER use outriggers from one model on another model.
CLOSE and secure cage after entering platform.

Safety Rules and Operating Instructions

INSPECT the machine thoroughly for cracked welds, loose or missing hardware, hydraulic leaks, damaged

control or power cables and loose wire connections.

NEVER use the machine as a freight or personnel elevator.
NEVER recharge battery near sparks or open flame; batteries that are being charged emit highly explosive

hydrogen gas.

AFTER USE secure the work platform against unauthorized use by turning key switch off and removing key.
NEVER replace any component or part with anything other than original UpRight replacement parts without

the manufacturer's consent.

NEVER sit, climb, or stand on the
platform guardrails or midrail.

NEVER attempt to

move the UpRight

Lift with people or

materials on the

platform or with
the platform

elevated.

NEVER elevate platform without
first leveling the base.

Outrigger Installation

Operation

1. Remove the outriggers from storage locations
on sides of mast.

2. Insert into outrigger socket in base (Figure 1).

3. Push in until locking pin engages hole in end of
outrigger. Pull outward on outrigger to ensure
engagement.

4. Repeat the above steps for all other outriggers.
Make sure all four (4) locking pins are engaged.

5. Level the base, centering the bubble in the orbit
level on the base by adjusting the screwjacks at
the end of each outrigger (Figure 1). DO NOT
release the tension on an outrigger, by turning
counterclockwise, to level base.

6. All four (4) screwjack pads must be in solid

contact with a firm surface and each outrigger
indicator light must be lit before the platform
is elevated.

Before operating UL Lift insure that: the operator has
been thoroughly trained on this machine, the opera­tor has read, fully understands and follows this
Operator Manual and the Scaffold Industry
Association's MANUAL OF RESPONSIBILITIES, the
unit has been properly set up with all four (4) outrig­gers properly installed and the base leveled, and the
machine has passed the Safety Interlock Test.

Note: Platform will not elevate unless all four
outriggers are properly installed with screwjack
pads firmly in contact with floor and each outrig­ger indicator lamp lit.

1. Check for external damage to the mast.

2. For AC units connect power unit plug to exten­sion cord (12 ga. (1.5 mm²) conductor minimum
and 50 ft. (15 m) in length maximum).
Connect extension cord to properly grounded
outlet of proper voltage and frequency.

3. Turn Key to ON, Key Switch is located on the
left side of the mast (Figure 2).

4. Pull out on Lower Emergency Stop Button,
located on the left side of the mast (Figure 2), to
turn switch ON. In the event of an emergency
push the button in to cut power to all controls.

5. Enter the platform by pulling out on the locking
pin and lifting up on the upper half of the cage.

6. Lower upper half of the cage after entering
platform making sure locking pin is engaged.

7. Check that the area above the platform is clear
before elevating the platform.

8. Pull out on Emergency Stop Button, located on
platform control panel (Figure 2). In the event of
an emergency push the button in to cut power to
all controls.

9. Push both the middle and top buttons (POWER
and UP), on the Control Box (Figure 2), at the
same time to elevate the platform. Release the
buttons to stop.

10. Check that the area below the platform is clear
before lowering the platform.

11. Push both the middle and bottom buttons
(POWER and DOWN) at the same time to lower
the platform. Release the buttons to stop.

12. After use, secure unit from unauthorized use by
turning Key Switch to OFF and remove key.

EMERGENCY LOWERING

If the platform should fail to lower, NEVER
climb down the mast.

Safety Interlock Test

NEVER perform this test from the platform.

Ask a person on the ground to open the Emer­gency Lowering Valve to lower the platform.

Serial Number 15001 - 21690

This valve is located through a cutout in the power
unit cover on the left side of the mast (Figure 3).

1. Pull the knob out and turn
Emergency Lowering Valve.

2. To close the Emergency Lowering Valve, turn
the knob until it snaps back in.

/4 turn to open the

Serial Number 21691 - Current

The Emergency Control Valve Knob is located at
the rear of the machine. (Figure 3).

1. Open the valve by pulling and holding the
knob.

2. To close the Emergency Lowering Valve,
release the knob.

Once the platform is fully lowered, be certain that the
Emergency Lowering Valve is closed again. The
platform will not elevate if the Emergency Lowering
Valve is open.

NOTE: Optional auxiliary platform lowering
circuit allows operator to lower platform when
power source is interrupted. A warning light on
chassis controls shines when batteries for auxil­iary platform lowering circuit are low (Figure 3).
Batteries for warning light are located inside
chassis control box.

1. Properly install all four (4) outriggers and level
base.

2. Release the tension on one (1) outrigger by turn­ing the screwjack counterclockwise, until the
indicator lamp is no longer lit.

3. While standing on the ground activate the control
panel to elevate the platform. Platform should
not elevate.

4. Re-level the base with all four (4) outriggers then
repeat step 2 with another outrigger.

5. Repeat steps 2 , 3 & 4 until all four (4) outriggers
have been tested.

DO NOT use a machine that elevates when the
tension has been released on an outrigger. Ma-

chine must be repaired before using.

Battery Maintenance

Hazard of explosive gas mixture. Keep
sparks, flame and smoking materials away
from battery.

Always wear safety glasses when working
with batteries.

Battery fluid is highly corrosive. Rinse
away any spilled fluid thoroughly with
clean water.

Always replace battery with UpRight battery
or manufacturer approved replacement
weighing at least 52 lbs. (23.6 kg) each.

Check battery fluid level daily, especially if
work platform is being used in a warm, dry
climate.

AFTER USE EACH DAY

1. Ensure that the platform is fully lowered.

2. Park the machine on level ground, preferably
under cover.

3. Secure against vandals, children or unautho­rized operation by turning the Key Switch to
OFF and remove the key.

3

If electrolyte level is less than
plates add distilled water only. DO NOT use tap
water with high mineral content, it will shorten
battery life.

Keep terminals and tops of batteries clean.
Refer to the Service Manual to extend battery life

and for complete service instructions.
