require a power cord with three leads plus an
earth ground.
3.1.1 Make sure that rear wheel (item 51, Figure
B, page 5) rotates counterclockwise.
Note: the power supply must be con-
nected to perform the above test only.
4 Install the balancer above the work station on a
trolley.
4.1 The trolley should have sufficient travel to allow
the operator to reach the entire work area. Refer

OPERATION INSTRUCTIONS
ALWAYS DISCONNECT THE POWER SUPPLY IN AC-
CORDANCE WITH OSHA’S LOCKOUT/TAGOUT PRO-
CEDURES (29 CFR 1910.147) BEFORE PERFORMING
ANY MAINTENANCE OR REPAIRS.
1 Turn on the power.
2Prior to use or daily, perform the following tests.
2.1 Make sure that the dual anti-tie down control
handles (the top and the rear handles) are work-
ing correctly. Depress one trigger, then pause
one second and depress the other trigger and the
tool should not start. Repeat this procedure re-
versing the triggers. Depress both triggers si-
multaneously (within one half second of each
other) and the tool should start. With the tool run-
ning, release one trigger and the tool should
stop. Continue holding the depressed trigger
and then depress the other trigger. The tool
should not start. Repeat this procedure holding
the other trigger. If the tool malfunctions, remove
it from service and report the problem to your su-
pervisor immediately.
2.2 Make sure that the Buster IV moves freely on its
balancer.
3 Making the cut.
If an elevating platform is used, the operator can keep
the Buster IV in a horizontal position during most of
the split.
Always avoid using pressure; instead, guide the Bust-
er IV.
Step 3.1 is necessary only during the operators’
learning period.
3.1 Mark the center of the backbone of the beef with
a knife.
3.2 Start the Buster IV.
3.3 Saw through the tail bone (using the knife mark
as a guide).
3.3.1 The idler end of the Buster IV should be
pointing upward while sawing through the
tail bone.
3.3.2 Do not pressure the Buster IV; guide the
Buster IV.

3.4 When the tail bone hits the crossbeam of the
Buster IV, saw until the tail bone breaks apart and
the Buster IV is allowed to continue its path down
the backbone of the beef.
3.4.1 The drive end of the Buster IV should be
lower than the idler end while sawing
through the tail bone.
3.5 After the tail and aitch bones have been split, saw
through the loin area.
3.5.1 The Buster IV should be in a horizontal po-
sition during this cut.
3.5.2 Do not pressure the Buster IV; guide the
Buster IV to ensure a straight cut.
3.6 Saw through the shoulder and neck of the beef.
3.6.1 The idler end of the Buster IV should be
pointing downward while sawing through
the shoulder and neck.

press both triggers simultaneously (within
one half second of each other) and the tool
should start. With the tool running, release
one trigger and the tool should stop. Con-
tinue holding the depressed trigger and then
depress the other trigger. The tool should
not start. Repeat this procedure holding the
other trigger. If the tool malfunctions, re-
pair or remove it from service immediately.
