The EASTWOOD 3”, ADJUSTABLE HEAD CUT-OFF TOOL offers a full 50° (+- 25° ) of additional head
angle adjustability to safely access areas difficult to reach with ordinary pneumatic Cut-Off tools. The
reversible feature allows the user to choose the direction of the resulting “spark-shower” to avoid
injury and property damage. A high-torque, ball bearing supported, 4 vane motor provides smooth
operation and long life. Speed is easily controlled with a variable speed control knob while motor
activation is by paddle control.

READ INSTRUCTIONS
• Thoroughly read and understand these product instructions before using
this tool. Failure to follow all warnings can result in tool damage or serious
physical injury.
• Keep these product instructions for future reference.
EYE INJURY HAZARD!
• Rapidly rotating surfaces can eject metal particles, dirt and oils at high ve-
locity. Always wear ANSI approved eye protection when operating this tool.
HEALTH AND INJURY HAZARDS!
• Dust and fine particulate matter is generated during the sanding/grinding
process which can contain toxic substances such as lead, silica, solvents
and others. Breathing this dust and fine particulate matter can cause many
serious respiratory health conditions. Always use NIOSH approved respira-
tory protection while using this tool.
HEARING DAMAGE HAZARD!
• The Eastwood Adjustable Head, Cut-Off Tool emits high sound levels while
operating. Use ANSI approved ear protection when operating this tool.
BURST HAZARD!
• Do not exceed 90 psi (6.3 bar) of tool inlet pressure. Permanent tool damage
and/or bursting could occur and cause personal injury.
DANGER indicates a hazardous situation which, if not avoided, will result in death or serious injury.
WARNING indicates a hazardous situation which, if not avoided, could result in death or serious injury.
CAUTION used with the safety alert symbol, indicates a hazardous situation which, if not avoided,
could result in minor or moderate injury.

The following explanations are displayed in this manual, on the labeling, and on all other information
provided with this product:

INJURY HAZARD!
• This tool has high-speed, highly abrasive cutting surfaces which can quickly
cause severe injury. Keep fingers and hands away from moving parts when
operating. Wear thick, well-fitting work gloves and keep loose clothing,
sleeves, cords, jewelry and hair away from moving parts.
• Always disconnect tool from air supply when changing Cut-Off Wheels to
prevent accidental tool starting and potential severe injury.
• This tool will eject a trail of sparks at high speed which can ignite flammable
materials or injure others nearby. Do not operate in the vicinity of flammable
materials and keep all persons and pets away from the work area.
• Do not force tool or exert side forces on Cut-Off Wheel while cutting as
the tool body can suddenly kick back or twist causing severe hand or wrist
injury. Cut-Off Wheels can shatter with excessive side force causing them to
disintegrate and eject sharp pieces at high velocity.
• Always make sure the workpiece being cut is securely clamped or anchored
to avoid sudden movements which could result in injury.
• Frequently inspect Cut-Off Wheel and tool condition. If cracks or chips
develop, discontinue tool use immediately and replace damaged Wheel.
ONLY USE replacement Wheels rated at 16,000 RPM or greater. Severe
injury can result in the event of Cut-Off Wheel failure.
PINCH HAZARD!
• Keep fingers from between moving parts when adjusting the angle of
the Head.
VIBRATION INJURY HAZARD!
• This tool will vibrate during use! Repeated exposure to vibration may
cause physical injury.

SET-UP & CONNECTION
• Be sure that the air supply to the tool
is clean and dry. Moisture in the sup-
ply line will quickly damage the motor
and valves.
• A minimum 3/8” I.D. air line should
be used for optimal performance.
• Thread a suitable 1/4” Male Quick-
Disconnect Fitting (included) into the
air inlet of the tool using TFE thread
sealing tape (not included).
OPERATION
• Rotate the Knob located at the rear of
the tool handle and under the Throttle
Paddle to regulate motor speed (FIG
5). This Knob offers 30° of travel.
Note that rotating in a Clockwise
direction will result in higher speed
while Counter-clockwise will
decrease speed.
• Flip the Safety Lever forward and
Depress Throttle Paddle inward to
operate tool (FIG 6).
• Always maintain a firm grip while
operating tool, do not force but allow
the rotational speed of the Cut-Off
Wheel to do the work.
• Be sure that the workpiece is
clamped down or held securely to
minimize the danger of injury while
operating tool.

ing the Knob in a Clockwise direction
will allow the tool to run forward while
Counter-clockwise will reverse the
wheel rotation direction.
ADJUSTING
HEAD ANGLE
• Lift the Locking Lever of the Clamping
Collar (FIG 8).
• Grip the head firmly and snap it up or
down 25°.

USAGE TIPS
• The reversing feature is very useful for controlling the direction of spark-shower discharge.
Plan your tool position and direction of rotation while cutting to minimize and redirect the spark
shower.
• Keep the cutting edge of the Cut-Off Wheel tangent to the work surface whenever possible to
minimize uneven wear or damage and maximize useable wheel life.
MAINTENANCE
• Add several drops of air tool oil before each use by dropping directly into the air inlet.
• If tool is to be unused for an extended period, add 10 drops of air tool oil directly to the air
inlet, rotate the tool motor by hand several times to distribute the oil throughout the motor and
gearbox then store the tool, handle up.
• Periodically, with the air supply disconnected, check cut-off wheel condition and Angle Adjust-
ing Screw tightness.
