SAFETY

PROTECT YOURSELF AND OTHERS FROM SERIOUS INJURY OR DEATH.

KEEP CHILDREN AWAY. BE SURE THAT ALL INSTALLATION, OPERATION,

MAINTENANCE AND REPAIR PROCEDURES ARE PERFORMED ONLY BY

QUALIFIED INDIVIDUALS.

EQUIPMENT DAMAGE

ELECTRIC SHOCK can kill.

1) The equipment is not waterproof. Using
the unit in a wet environment may result
in serious injury. Do not touch equipment
when wet or standing in a wet location.

2) The unused connectors have power on
them. Always keep the unused connec­tors covered with the supplied protective
panels. Operation of the machine without
the protective panels may result in injury.

3) Never open the equipment without first
unplugging the power cord or serious
injury may result.

4) Verify the customer-supplied power
connections are made in accordance
with all applicable local and national
electrical safety codes. If none exist,
use International Electric Code (IEC)

950.

5) Never remove or bypass the equipment
power cord ground. Verify the equipment
is grounded in accordance with all appli­cable local and national electrical safety
codes. If none exist, use International
Electric Code (IEC) 950.

1) Do not plug in the power cord without first
verifying the equipment is OFF and the
cord input voltage is the same as required
by the machine or serious damage may
result.

2) Always verity both the pinion and wheels
are fully engaged before applying power
or equipment damage may occur.

3) Do not leave the equipment unattended.

4) Remove from the worksite and store in
a safe location when not in use.

FALLING EQUIPMENT
can cause serious
personal injury and
equipment damage.

Faulty or careless user installation is
possible. As a result, never stand or
walk underneath equipment.

POSSIBLE.

MOVING PARTS can
cause serious injury.

READ INSTRUCTIONS.

Read the instruction manualbefore
installing and using the equipment.

2

1) Never try to stop the pinion from moving
except by removing power or by using the
STOP control.

2) Do not remove any protective panels,
covers or guards and operate equipment.

HIGH FREQUENCY WARNINGS

SPECIAL PRECAUTIONS ARE REQUIRED WHEN USING PLASMA,

TIG OR ANY WELDING PROCESS THAT USES HIGH FREQUENCY

TO STRIKE AN ARC.

WARNING: HIGH FREQUENCY CAN EFFECT MACHINE

Read the precautions below before installing and using the equipment.

OPERATION AND THEREFORE, WELD QUALITY.

PRECAUTIONS:

1) Some plasma or welding cables are strong sources of high frequency interference.

NEVER lay a plasma or welding cable across the controls of the machine.

2) Always physically separate the plasma or welding cable leads from the machine
cables. For example, the plasma or welding cable leads should NEVER be bundled
with a pendant cable or the machine power cord. Maximize the separation between
any machine cables and the plasma or welding cables.

3) Strictly follow the grounding procedures specified for the plasma or weldingunit.
NOTE: Some plasma and welding units produce exceptionally large amounts of high
frequency noise. They may require a grounding rod be driven into the earth within six
feet (2 meters) of the plasma or welding unit to become compatible with an automatic
cutting or welding process.

4) If the high frequency is produced using a spark gap, adjust the points so the gap is as
small as possible. The larger the gap, the higher the voltage and the higher the inter­ference.

5) Some plasma or welding units will inject high frequency interference into the AC
power line. Use separate power line branches whenever possible to power the
plasma or welding source and the machine. Do not plug them into the same outlet
box.

6) High frequency noise may enter the machine through the plasma or welding supply
remote contactor leads. Some plasma and welding sources can produce noise spikes
of up to several thousand volts. These sources are not compatible with automated
cutting and welding equipment. It is recommended that the remote contactor leads on
these plasma or welding sources not be connected to the machine. An alternate
solution is to purchase a separate remote contactor isolation box.

GENERAL INFORMATION

The Pitbull SPB-3000 beveling machine is a portable milling unit designed for machining plate
edges before welding. Simple to operate, the Pitbull is effective and efficient for bevel angles from
0º to 60º and bevel width “b” up to 1.02'' (26 mm). With additional equipment it can be used for

angles up to 80º.

Figure 1: Reference drawing showing Bevel Angle (ß),
Bevel Face Width (b), Bevel Depth (d) and Depth of Cut (c).

Before starting operation, read this manual carefully

and pay particular attention to safety conditions.

MACHINE COMPONENTS

The Pitbull consists of six (6) major components as shown in Figure 2. The following sections
describe each of these components in detail.

1. Carriage

2. Milling unit

3. Milling unit holder

4. Rail

5. Rail alignment clamp

6. Metal chip container

Figure 2: Major Components of the Pitbull

CARRIAGE

The carriage precisely transmits the milling unit along the rail at operator-controlled speed. The
carriage and rail are a set. DO NOT REMOVE THE CARRIAGE FROM THE RAIL. The carriage
can only be moved when the milling unit is connected and the main motor is running. The major
carriage components and control mechanisms are called-out in Figure 3.

1.1 Chassis

1.2 Carriage casing

1.3 Electronic module

1.4 Milling unit interlock

1.5 Main switch

1.6 Milling unit switch

1.7 Carriage direction switch

1.8 Carriage speed potentiometer

1.9 Emergency stop switch

1.10 Milling unit power supply connection

Figure 3: Carriage components and controls

The milling unit switch (1.6) consists of a green ST AR T button (I), a red STOP button (O) and an
overload indicator light. The indicator flashes when the main motor is operating near overload. The

carriage direction switch has three (3) positions - forward, reverse, and stationary .

MILLING UNIT

The milling unit is a special milling head mounted directly to the motor shaft. The unit is equipped
with bevel depth adjustment. Major components and controls of the milling unit are called-out in
Figure 4.

2.1 Main motor

2.2 Milling head casing

2.3 Drive ring

2.4 Drive ring lever

2.5 Milling head

The milling head requires seven (7)
machining inserts. Each insert is
held in place with a screw and can
be replaced or repositioned as
needed. The insert key is used for
these screws.

Figure 4: Milling Unit

Assemble the milling head casing (2.2) and the milling unit holder (3), then use the drive ring

(2.3) to regulate the bevel depth. On the drive ring, one unit corresponds to 1 mm.

MILLING UNIT HOLDER
The milling unit holder or bracket head assembly mounts to the carriage and positions the
milling unit at a fixed angle. The milling unit holder must be changed to change the bevel angle.

The standard SPB-3000 package includes four (4) holders -- 0º, 22.5º, 37.5º, 45º. Holders are also
available for 15º, 20º, 25º, 30º, 55º, and 60º. Figure 5 shows the major features of the milling unit
holder.

MACHINE COMPONENTS, CON’T

RAIL
The standard rail consists of two easily disconnected tip segments and two moveable end
clamps, as shown in Figure 6, and spans 2 m long. For longer bevel lengths, one-meter center

segments can be added between the tip segments.

4.1 Tip segment – left

4.2 Tip segment – right

4.3 End clamp

4.4 Clamp screw

Figure 6: Rail

RAIL ALIGNMENT CLAMP
Rail alignment clamps position and secure the rail against the work piece. Use the clamp lever,

shown in Figure 7, to press the rail against the work piece and minimize the effects due to out-of-flat
plate. Three rail alignment clamps are supplied with the standard SPB-3000. Rail alignment clamps
are adjusted during operation. At all times, two out of three rail alignment clamps should be
clamped.

5.1 Alignment clamp body

5.2 Alignment clamp arms

5.3 Alignment clamp lever

5.4 Adjusting screw

Figure 7: Rail Alignment Clamp

Adjusting screw (5.4) is used to correct for work piece thickness. Proper alignment clamp

operation requires a snug fit of work piece to alignment clamp. An alignment clamp can be moved
only when the lever (5.3) is in the up position. Figure 7 shows the lever in the down position.
