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 could eject sparks at high speed 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 drill or exert excessive side forces on tool while in use as the drill
body can suddenly kick back or twist causing severe hand or wrist injury.
Drill bits can suddenly break with excessive side force.
• Always make sure the workpiece is securely clamped or anchored to avoid
sudden movements which could result in injury.
• Always disconnect Drill from air supply when changing drill bits or accessories
to prevent accidental tool starting and potential serious injury.
• Frequently inspect Chuck and overall tool condition. If damage is discovered,
discontinue tool use immediately. ONLY use drill bits or accessories rated for
700 RPM or greater use, otherwise serious injury can result in the event of failure.

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.
OPERATION
• Open the Chuck Jaws by rotating the shell in a Counter-Clockwise direction (as viewed
from the open end).
• Insert drill bit or accessory shank into Chuck Jaws.
• Close the Chuck Jaws by rotating the shell in a Clockwise direction (as viewed from the
open end).
• Insert Chuck Key into one of three bores of the Chuck with the gear teeth engaged and
turn Clockwise to tighten Chuck Jaws (FIG 2).
• Connect air supply, depress Trigger to begin rotating action. Speed is regulated by pressure
applied to the Trigger.
• For forward (normal drill rotation) direction, disconnect from air supply, move Forward/Reverse
Lever fully to the “F” position (FIG 2).
• To reverse drill, disconnect from air supply, move Forward/Reverse Lever fully to the
“R” position.
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, then store
the tool, handle up.
• With the air supply disconnected, open chuck jaws fully and using a #2 Philips screw driver,
periodically check that the chuck retaining screw is tight. Note: This screw is left-hand
threaded, turn counter-clockwise to tighten.
