Safe Operation
Knowl edge of the in for ma tion in this man ual, and
proper train ing, pro vide a ba sis for safely op er at ing
the X33RT / X27RT. Know the lo ca tion of all the
con trols and how they op er ate to act quickly and re -
spon si bly in an emergency.
Safety de vices re duce the like li hood of an ac ci -
dent. Never dis able, mod ify, or ig nore any safety
de vice. Safety alerts in this man ual in di cate sit u a -
tions where ac ci dents may occur.
If any mal func tion, haz ard or po ten tially un safe
con di tion re lat ing to ca pac ity, in tended use, or safe
op er a tion is sus pected, stop the op er a tion of the
RT and seek assistance.
The op er a tor bears ul ti mate re spon si bil ity for fol -

Electrocution Hazards
The RT is an all metal ae rial work plat form and is
not elec tri cally in su lated. Do not op er ate it near
elec tri cal con duc tors. Re gard all con duc tors as be -
ing en er gized. Do not op er ate out side dur ing a
thunderstorm.
❑ Minimum safe approach distance
Min i mum safe ap proach dis tances to energised
power lines and their as so ci ated parts must be ob -
served wile op er at ing the RT.
Figure 1. - Minimum Safe Approach Distance
The RT is not electrically insulated. Death or
serious injury can result from contact with,
or inadequate clearance from, an energised
conductor. Do not go closer than the
minimum safe approach distance as defined
by ANSI.
ANSI pub li ca tions de fine min i mum dis tances that
must be ob served when work ing near bus bars and
energised power lines. Fig ure 1 and Ta ble 1 are re -
printed cour tesy of the Scaf fold in dus try As so ci a -
tion, ANSI/SIA A92.5.
