Safety Rules and Operating Instructions
NEVER operate the machine within ten feet of power lines.
THIS MACHINE IS NOT
INSULATED.
NEVER operate the machine without first surveying the work area for surface hazards such as holes, drop­offs, bumps and debris.
NEVER operate the machine if all guardrails are not properly in place and secured with all fasteners prop­erly torqued.
SECURE chain across entrance after mounting platform. NEVER use ladders or scaffolding on the platform. NEVER attach overhanging loads or increase platform size. LOOK up, down and around for overhead obstructions and electrical conductors. DISTRIBUTE all loads evenly on the platform. See the back cover for maximum platform load. NEVER use damaged equipment. (Contact UpRight for instructions. See toll-free phone number on back
cover.)
NEVER change operating or safety systems. INSPECT the machine thoroughly for cracked welds, loose hardware, hydraulic leaks, damaged control
cable, loose wire connections and wheel bolts.
NEVER climb down elevating assembly with the platform elevated. NEVER perform service on machine while platform is elevated without blocking elevating assembly. 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 with-
out the manufacturer’s consent.
NEVER elevate the platform
or drive the machine while
elevated unless the machine is
on firm level surface.
NEVER sit, stand, or climb
on guardrail or midrail

PRE-O
PERATIONSAFETYINSPECTION(FIGURES
Carefully read, understand and follow all safety rules, operating instructions, labels and the Scaf­fold Industry Association’s MANUAL OF RESPONSIBILITIES. Perform the following steps each day before use.
1. Open module covers and inspect for damage, oil leaks or missing parts.
2. Check the level of the hydraulic oil with the platform fully lowered. Oil should be visible to full line on tank. Add hydraulic fluid if necessary.
3. Check that fluid level in the batteries is correct (See Battery Maintenance, page 7).
4. Verify that batteries are charged.
5. Check that AC extension cord has been disconnected from charger.
6. Check that all guardrails are in place with fasteners properly tightened.
7. Inspect the machine thoroughly for cracked welds, loose hardware, hydraulic leaks, damaged control cable, loose wire connections and wheel bolts.
8. Move the machine, if necessary, to an unobstructed area to allow for full elevation.
9. Pull Chassis Emergency Stop Switch to the ON position.
10. Pull Platform Emergency Stop Switch to the ON position.
11. Turn and hold the Chassis Key Switch to CHASSIS. Push the Chassis Lift/Lower Switch to lift position and fully elevate the plat­form.
12. Visually inspect the elevating assembly, lift cylinder, cables and hoses for cracked welds, loose hardware, hydraulic leaks, loose wire connections and erratic oper­ation. Check for missing or loose parts.
13. Verify that depression mecha­nism supports have fully rotated into position under each module.
14. Turn and hold the Chassis Key Switch to CHASSIS. Partially lower the platform by pushing the Chassis Lift/Lower Switch to LOWER, and check operation of the audible lowering alarm.
15. Pull out on the Emergency Lowering Knob to check for proper operation. Once the platform has lowered completely, release the knob.

ATTERYMAINTENANCE
WARNING
!
Hazard of explosive gas mixture. Keep sparks, flame, and smoking material away from battery.
Always wear safety glasses when working near batteries. Battery fluid is highly corrosive. Thoroughly rinse away any spilled fluid with
clean water. Always replace batteries with UpRight batteries or manufacturer approved
replacements weighing 62 lbs. each.
• Check warm, dry climate.
•If water ONLY. Do not use tap water with high mineral content, as it will shorten battery life.
• The battery and cables should be inspected regularly for signs of cracks in the case, electrolyte leakage and corrosion of the terminals. Inspect cables for worn spots or breaks in the insulation and for broken cable terminals. Keep terminals and tops of batteries clean.
• Refer to the Service Manual to extend battery life and for complete service instruc­tions.

ATTERYCHARGING
Charge the batteries at end of each work shift or sooner if batteries have been discharged.
WARNING
!
Charge batteries only in a well ventilated area. Do not charge the batteries if the work platform is near a source of sparks or
flames. Permanent damage to the batteries will result if the batteries are not
recharged immediately after discharging. Never leave the battery charger operating for more than two days. Never disconnect the cables from the batteries when the battery charger is
operating. Keep the battery charger dry.

Power Module
1. Check battery fluid level. If electrolyte level is lower than 3/8 in. (10 mm) above plates add dis­tilled water only.
2. Connect an extension cord to the battery charger plug at end of left module. Connect exten­sion cord (12 gauge [1.5 mm²] minimum conductor diameter; 50 ft. [15m] maximum length) to properly grounded outlet of correct voltage and frequency.
3. The battery charger turns on automatically after a short delay.
NOTE: The battery charger circuit must be used with a GFI (Ground Fault Circuit
Interrupt) outlet.
DO NOT operate the machine while charger is plugged in.

REVENTATIVEMAINTENANCE
P
The complete inspection consists of periodic visual and operational checks, together with all nec­essary minor adjustments to assure proper performance. Daily inspection will prevent abnormal wear and will prolong the life of all systems. The inspection and maintenance schedule is to be performed at regular intervals. Inspection and maintenance shall be performed by personnel who are trained and familiar with mechanical and electrical procedures.
WARNING
!
Before performing preventative maintenance, familiarize yourself with the operation of the machine.
Always block the elevating assembly whenever it is necessary to enter the scissor assembly to perform maintenance while the platform is elevated.
The preventative maintenance table has been designed to be used primarily for machine service and maintenance repair. Please photocopy the following page and use the table as a checklist when inspecting the machine for service.
