All Snorkel scissor lifts in the Snorkel
'SRT, SR and S/RT Series are fi tted
with a very important safety feature,
a 'Stabiliser/axle/scissor Interlock'
system that prevents the stabilisers
being moved while the platform is
elevated, and prevents the platform
being raised if the rear axle is oscil-
lated and the stabilisers are not set
or the machine is tilted.
The correct operation of the Stabi-
liser/scissor Interlock is critical to
ensure that the Scissor is operated
safely and with minimum risk.
DANGER
To ensure the interlock system is
functioning correctly before op-
erating the scissor the following
test must be carried out prior to
operation each day, in conjunction
with all other relevant daily pre-op-
erational checks:
Stabiliser locked out when plat-
form is elevated test the stowed
position. (Continued on to next
