SAFETY PRECAUTIONS

IN GENERAL

When using rotating head cutting equipment, basic safety precautions should always
be followed to reduce the risk of personal injury.

Operate this tool only in accordance with specic operating instructions.

Do not override the deadman switch on the power unit. Locking down, ob-

WARNING:

DRESS CONSIDERATIONS

structing, or in any way defeating the deadman switch on the power drive unit
may result in serious injury.

Model 302 Tube Squaring Machine

Use standard safety equipment. Hard hats, safety shoes, safety harnesses, protec­tive clothes, and other safety devices should always be used when appropriate.

Use safety glasses. Do not operate cutting tools without eye protection.

Dress properly. Do not wear loose clothing or jewelry. They can be caught in rotat-

ing and moving parts. Avoid slippery oors or wear nonskid footwear. If you have

long hair, wear protective hair covering to contain it.

WORK AREA

Keep the work area clean. Keep the area well lit. Keep electrical cords, cables, rags,
rigging straps, and etc. clear of rotating equipment. Do not use power-cutting tools

in the presence of ammable liquids and gasses.

Keep visitors away. Do not let visitors or untrained personnel at or near operating
tools. Enforce eye protection requirements for all observers.

Do not over reach. Keep proper footing at all times.

Stay alert. Watch what you are doing. Use common sense. Do not operate tools
when you are tired.

TOOL CARE

Maintain tools with care. Keep tools in good operating condition. Sharp tool bits
perform better and safer than dull tool bits. Well maintained tools function properly
when needed.

Check for damaged parts. If a tool has malfunctioned, been dropped or hit, it must
be checked for damage. Run no-load tests and feed function checks. Do a com­plete visual inspection.

Electric motors. Use only with proper AC voltage power sources and observe all
normal electric shock hazard procedures.

Do not abuse power and control cords. Pulling or running over cords and cables can
result in electrical shock hazards and malfunctions. Keep control and power cords

out of all cutting uids and water.

Hydraulic drives. Observe proper procedures for electrically driven power sources.
Avoid damage to hydraulic lines. Keep quick-disconnects clean. Grit contamination
causes malfunctions.

Air tools. Check the exhaust mufer. Broken or damaged mufers can restrict air
ow or cause excessive noise. Use air motors only with a ltered, lubricated and

regulated air supply. Dirty air, low-pressure air or over pressure air will cause mal­functions, including delayed starting.

AREA EQUIPMENT

Secure work. Whenever possible use clamps, vises, chains and straps to secure
pipe.

Make sure the tool is secured; it is safer to have both hands free to operate the tool.

TOOL USE

Use the right tool and tool bit for the job. Do not use a tool, which is incorrect for the
job you are doing.

Keep the tool bits fully engaged in the tool bit holders. Loose bits are a safety
hazard.

Model 302 Tube Squaring Machine

Disconnect power supply during setup and maintenance. Use all ‘Stop’ or Shut off’
features available when changing or adjusting tool bits, maintaining the tool, or when
the tool is not in use.

Remove adjusting keys and wrenches before applying power to the equipment. De­velop a habit of checking the tool before turning it on to make sure that all keys and
wrenches have been removed.

Do not force tools. Tools and tool bits function better and safer when used at the
feed and speed rate for which they were designed.

Do not reach into rotating equipment. Do not reach into the rotating head stock to

clear chips, to make adjustments, or to check surface nish. A machine designed to

cut steel will not stop for a hand or an arm.

Handle chips with care. Chips have very sharp edges and are hot. Do not try to pull
chips apart with are hands; they are very tough.

Avoid unintentional starts. Do not carry or handle tools with your hand on the op­erating switches or levers. Do not lay the tool down in a manner that will start the

drive. Do not allow the tool to ip around or move when adjusting or changing tool

bits.

Store idle tools properly. Disconnect tools from the power source and store in a safe
place. Remove tool bits for safe handling of the tool.

TRI TOOL INC.

The Model 302 Tube Squaring Tool is a bench mounted machine designed specif­ically to prepare tubes for autogenous welding. The 302 will face (square) .188” to

2.375” (4.8 mm to 60.3 mm) outside diameter tubing with a wall thickness up to .200”
(5.1 mm). The 302 uses an OD Saddle Clamping System for holding and rounding
the tube. The 302 accepts its own torque through the Saddle Clamping System.
The standard Saddle Clamping System requires a straight length of tube .875” (22.2
mm) long. Automatic clamping can be provided using a pneumatic clamping system.
Speed control is provided with a variable speed electric drive or a pneumatic drive
motor. Feed is provided by a lever action for excellent feed control. A microfeed sys­tem provides an accurate controlled feed alternative.

MAINTENANCE

All components should be cleaned and coated with a light lm of oil prior to use.

Use a clean, non-detergent oil, preferably SAE 10 (90 SSU) or lighter.

The air supply for the Model 302A with an air motor should include an adequate lter,

regulator and lubricator (FRL).

NOTE:

If the Model 302 is operated in the vertical position (cutting head up), turn it upside
down and remove the chips and/other debris after each bevel has been completed.

WARNING:

Bearing and gears are to be lubricated using a high string utility grease (P/N 68-

0020).

The Motor Warranty is void if damage occurs from contaminated air or lack of
lubrication.

Tool life may be severely shortened, unless chips and/or debris, that have
been deposited on the cutting head during the machining operation, are re­moved.

AIR MOTOR LUBRICATION

Disassembly of a power unit voids warranty, except when performed by a

WARNING:

No direct maintenance is normally required on the Air Motor.

TRI TOOL designated repair technician. (Letter of designation is required.)

However, the air supply must ow through a lter/regulator/lubricator (FRL) unit or

separate units before arriving at the air motor.

The FRL unit must be maintained as required (frequency dependent on the basic air

supply) to keep the water trap drained, lter cleaned and the lubricator oil reservoir
lled so that a drop of oil every two (2) to ve (5) seconds is owing.

If the Model 302A is to be left idle for 24 hours or more after being run on ‘wet’ air, it
is advisable to squirt oil directly into the air motor inlet and run the motor for two (2)
to three (3) seconds.

This will prevent rusting and ‘freezing’ of the rotor vanes.

Lubricant Recommendations:

The air motor requires a ‘Class 2’ lubricant, viscosity of 100 to 200 SSU at
100° F (38° C).

• TRI TOOL Inc. – Air Tool Lubricant (P/N 68-0022)

• AMOCO – American Industrial Oil No. 32

• Atlantic Richeld – Duro Oil S-150

• Chevron – A.W. Machine Oil 32

• Exxon – Nuto H32

• Shell – Tellus Oil 32

NOTE:

The bearings in either the air motor or the electric motor are sealed and do
not require any lubrication.
