Note:
Electrical contr ol boxes ar e differ ent for differ ent
power
supplies. Y ou must have the pr oper contr ol box for
your power supply . Refer to Figur es D–F on pages 7–9
for control box numbers for SEC 180 external brake
models.
For all other SEC 180 models, r efer to Figur e
1 below.
2.1 Attach
terminals to the appropriately rated pow -
er supply. See wiring diagram inside control
box cover for external brake models or refer to
Figure 1 below.
3 Install
a balancer above the work station on a trolley .

OPERATION INSTRUCTIONS
1 Plug in the SEC 180.
2 Each day, before you begin operation, perform the
following:
2.1 Make
sure that the SEC 180 moves freely on the
balancer.
2.2 Make sure that the control handle or handles
work
correctly . For single trigger tools: depress
the
trigger and the tool should start. Release the
trigger and the tool should stop. For dual trigger
tools: depress each trigger separately and the
tool should not start; depress both triggers si-
multaneously
(within one second of each other)
and the tool should start. Release either or both
triggers and the tool should stop. If the tool mal -
functions,
r emove it fr om service and r eport the
problem to your supervisor immediately .
Always
operate the tool with both hands on the
handles. Continue to hold the tool with both
hands
until the saw blade comes to a complete
stop.
2.3 Make sure that the electronic brake is working
correctly.
Depress the trigger / triggers to start
the saw; release a trigger and the saw blade
should
stop within 2.5 seconds. If the tool mal -
functions, r emove it fr om service and r eport the
problem to your supervisor immediately .
3 Make the cut.
3.1 Position the SEC 180 saw.
3.2 Depress
the trigger / triggers. Always use both
hands when operating the tool. Continue to
hold the tool with both hands until the saw
blade comes to a complete stop.
3.3 When
the desired cut is achieved, release a trig -
ger. This will stop the blade.
