Upright 9300, SL20 Series Operator's Manual
Upright SL20 Series is a self-propelled elevating work platform designed for a variety of indoor and outdoor maintenance and construction tasks. With its compact size and maneuverability, the SL20 Series is ideal for working in confined spaces or on uneven terrain.
The SL20 Series features a spacious platform that can accommodate up to two workers and their tools, and a maximum platform height of 20 feet. The platform is equipped with guardrails and a midrail for added safety, and the machine is equipped with an audible lowering alarm to warn of any unintended movement.
The SL20 Series is powered by a 24-volt DC electric motor, which provides quiet and emission-free operation. The machine is also equipped with a non-marking tires, which will not damage floors or other surfaces.

WARNING
All personnel shall carefully read, understand and follow all safety rules, operating instructions, and the Scaffold Industry Association’s MANUAL
OF RESPONSIBILITIES
of ANSI A92.6-1999
before performing maintenance on or operating any UpRight Aerial Work Platform.
Safety Rules
NEVER operate the machine within ten feet of power lines.
THIS MACHINE IS NOT
INSULATED.
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
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 without the manufacturer’s consent.

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.

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 the battery fluid levels daily, especially if the work platform is being used in a warm, dry climate.
• If the electrolyte level is lower than 3/8 in. (10 mm) above the plates, add distilled 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.

Battery Charger
!
W A R N I N G !
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.
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.

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.
!
W A R N I N G !
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.
