3.1 Safety Rules and
Precautions
Always observe the following safety rules and precau-
tions when using the LX 31/41 Work Platform:
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, drop-offs,
bumps and debris.
NEVER operate the machine if all guardrails are not
properly in place and secured with all fasteners properly
torqued.
SECURE and lock gate after mounting platform.
KEEP all body parts clear of outriggers when extending
or retracting.
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 unautho-
rized 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.
ALWAYS read, understand, and follow all safety rules
and operating instructions, and the Scaffold Industry
Association's MANUAL OF RESPONSIBILITIES (ANSI/SIA
A92.6-1990) before operating or performing mainte-
nance on any UpRight self propelled aerial work plat-
form.
DESIGN FEATURES
The LX 31/41 has the following features to insure safe
operation:
1. The Lift Valve will not energize unless the chassis is
level.
2. The Floating Front Axle locks in position upon
elevating the work platform.
3. A warning alarm sounds and Drive Valves are de-
energized, if the work platform should become
unlevel while elevated.
4. A motion alarm sounds when the work platform is
lowering.
5. The platform descent rate is controlled by an orifice.
The Lift Cylinder is equipped with a holding valve to
prevent descent should a leak develop.
6. The drive speed is limited to creep speed when
operating the work platform while elevated.
7. Drive will not operate while elevated unless the
Floating Front Axle is positioned parallel to the Rear
Axle.
8. Holding brakes are automatically engaged when the
Drive Valves are de-energized from the Controller or
from a loss of power.
9. The Platform and Chassis controls are each
equipped with an Emergency Stop Switch.
10. Up and Down Buttons are located in the Control
Module on the chassis for lifting and lowering the
work platform from ground level.
12. The Down Valve can be operated manually by
means of a cable linkage in the event of powered
function failure.
13. Dynamic braking, and runaway protection are
provided by the use of Counterbalance Valves in the
drive system.
14. A Level Sensor is used to sense when the machine is
unlevel, disabling lift functions, and drive when
elevated.
15. Drive is disabled when Outriggers are deployed.
16 When using outriggers, lift is disabled if outriggers
are not taking load.
