OPERATION
• Place the desired tool bit against
work piece and depress trigger to
actuate hammering. Always use
two hands to control tool.
• Speed is regulated by rotating
the knurled Knob located at
the underside of the Gun Grip.
To increase speed: rotate in a
Counter-Clockwise direction (as
viewed form the underside of the
Gun Grip). To decrease speed:
rotate Knob in a Clockwise
direction.
• Avoid running the Hammer freely
without a workload, permanent
internal tool damage can occur.
INJURY HAZARD!
• This tool has high-speed, highly aggressive chiseling 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.
• This tool may eject sparks during use which can ignite flammable materials
or injure others nearby. Do not operate near flammable materials and keep
all persons and pets away from the work area.
• Do not force tool while in use as the tool body can suddenly kick back
causing severe hand or wrist injury. Air Tool Bits may disintegrate with
excessive side force causing them to fracture and eject sharp pieces at high
velocity.
• Always make sure the workpiece is securely clamped or anchored to avoid
sudden movements which could result in injury.
• Frequently inspect condition of Air Tool Bits. If cracks develop, discontinue
tool use.
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 supply line will quickly
damage the motor and valves.
• A minimum 3/8” I.D. air line should be used for optimal performance.
• Thread the retaining spring onto the machined spiral-grooved end of the hammer body with the
protruding ear inward. Rotate the spring using the ear as a lever (
Fig 1
).
• Make sure the Hammer is disconnected from the air supply. The bit is slid into the bore of the
hammer drive piston using the spring to retain it. The Spring must be deflected by pulling firmly
outward and back so that the formed “U” fits over the flange portion of the tool shank (
Fig 2
).
This keeps the tool bit in place while hammering.
• To remove a bit, disconnect air supply, pull spring “U” outward and back and release tool bit
from bore.
INJURY HAZARD!
Disconnect air supply from the Hammer to prevent accidental starting and
potential injury while placing a tool bit in the bore.

MAINTENANCE
• Add several drops of air tool oil before each use directly into the air inlet.
• If Hammer is to be unused for an extended period, add 10 drops of air tool oil directly to the air
inlet then store the Hammer handle up.
