WORKING NEAR POWER LINES
DANGER
The lift is NOT insulated for use near electrical
power lines and DOES NOT provide protection
from contact with or close proximity to any
electrically charged conductor. Operator rmust
maintain a safe distance at all times. See Table 1
for minimum safe approach distances between
electrical power lines and lift. Always allow for
operator compartment movement due to gusty
winds. Always contact local power company
before working near power lines. Assume all
powerlines are live.
WARNING
Failure to observe the following rules can cause
serious injury or death! Authorized and trained
operator only!

Special Precautions
DISCHARGING THE CAPACITORS
WARNING
DO NOT make repairs or adjustments unless you
have been properly trained and authorized to do
so. Improper repairs and adjustments can create
dangerous operating conditions. DO NOT operate
an aerial work platform that needs repairs. Report
the need for repairs to your supervisor immedi-
ately. If repair is necessary, attach a DO NOT OP-
ERATE tag to the control handle and disconnect
the battery. DO NOT place tools on top of the bat-
tery. If a tool causes a short circuit, the high cur-
rent flow from the battery can cause personal in-
jury or property damage.
Some checks and adjustment are performed with
the battery connected. DO NOT connect the bat-
tery until the procedure instructs you to do so.
Never wear any metallic items on your fingers,
arms, or neck. Metal items can accidentally make
an electrical connection and cause injury.
Before performing any tests or adjustment, block
the aerial work platform to prevent unexpected
movement.
The capacitor in the transistor controller(s) can
hold an electrical charge after the battery is dis-
connected.
To avoid injury and prevent electrical shock, per-
form the following steps before doing any trouble-
shooting, adjustments, connecting, or discon-
necting a handset or PC:
1. Block the platform so that the drive wheels
are off the floor. See the Operator's Manual.
2. Turn the key switch to the OFF position.
3. Discharge the capacitors in the controllers.
DO NOT short across the motor controller
terminals with a screwdriver or jumper wire.
Remove the 200-ohm, 2-watt resistor before
reconnecting the battery.
