1. Safety
■ 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 SR2770. 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 emer gency.
Safety de vices re duce the like li hood of an ac ci -

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 SR.
Figure 1. - Minimum Safe Approach Distance
The SR 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 -

■ Pre-start Inspection
At the start of each work shift, the SR2770 shall be
given a vi sual in spec tion and func tion test. See the
“Daily In spec tion and Main te nance” chap ter 7, in
this man ual for a list of items to in spect and test.
DO NOT operate the SR2770 unless you are
trained and authorized, understand the
