Ø Check to ensure the machine has fuel before starting.
o NOTE: This machine takes unleaded fuel with octane 86 or above.
o NOTE: Always switch OFF the engine before checking the fuel or
re-fueling. DO NOT overfill with fuel.
OPERATIONAL SAFETY CHECKS
Ø ONLY to be operated by qualified personal who have read instructions.
o NOTE: Failure to read and follow instructions could result in electrical shock, fire,
property damage and/or serious injury!
Ø DO ensure all non-essential people are clear of the immediate work area.
Ø DO be attentive at all times. Keep your eye on the work piece. Always be in a sensible state
of mind and do not use the machine if you cannot fully concentrate.
Ø DO keep body parts, clothing & power cords clear of turning/cutting pieces. Stay alert and
use common since when using this tool.
Ø DO allow machine to reach operating speed before starting a hole.
Ø DO shut down machine while changing or adjusting cutting bits so as not to accidentally turn
machine on.
Ø DO remove adjusting wrenches prior to turning the machine on.
Ø DO be mindful that power tools can expose an operator to vibrations transmitted trough
contact with the machine. Prolonged exposure can lead to medical issues which should be
discussed with a medical professional.
Ø DO use a dust extraction system for cutting materials that create dust. The operator should
also wear a protective respiratory device.
Ø DO keep the engine at least 3 feet away from buildings or flammable objects during operation
as the engines exhaust can become very hot during operation.
Ø DO NOT make adjustments to machine while the machine is running.
Ø DO NOT switch off the machine when it is under load, except in an emergency.
Ø DO NOT leave the machine running when not in use.
Ø NO NOT touch the motor or motor parts while hot as burns may occur.

Ø DO NOT touch moving parts while the machine is running as death or dismemberment could
occur.
Ø DO NOT operate machine overhead (Inverted) when drilling “wet” type cores.
Ø DO NOT allow children or untrained personal to operate machine.
Ø DO NOT use this machine in the rain or a wet environment.
Ø DO NOT operate in the presence of explosive materials as power tools create sparks which
may ignite dust or fumes.
Ø DO NOT place anything on the motor while running.
Ø DO NOT drill into an area that may contain a live electrical wire/circuit.
Ø DO NOT use full water pressure when drilling with “wet” type bits! You need minimal water to
drill with these machines. Extreme water pressure can damage machine and cutting bits.
Ø DO NOT depress throttle engaging clutch when starting the motor as you do not want the core
bit to spin quickly while not held securely.
Ø DO NOT use this gas machine indoors.
Ø DO NOT smoke or allow flames around this gas machine.
HEALTH WARNINGS
Ø Certain dust created by drilling contains chemicals known to cause cancer, birth defects or
other reproductive harm. The examples of these chemicals are below:
o Lead from lead based paint.
o Crystalline silica from bricks, cement and assorted masonry products.
§ TO REDUCE RISK OF EXPOSURE TO THESE CHEMICALS, WORK IN A WELL
VENTILATED AREA WITH VACUUM SYSTEMS, RESPIRATORS AND WITH
ALL SUITABLE SAFETY EQUIPMENT.
Ø This machine’s exhaust contains poisonous carbon monoxide. Breathing in carbon
monoxide can lead to unconsciousness, injury or death.
o DO NOT run the engine without adequate ventilation and never run indoors.

Operations
Note
THOROUGHLY READ THROUGH THE ENTIRE MANUAL BEFORE
OPERATING THIS MACHINE!
PURPOSE
Ø The purpose of the GCD4 core drill is to drill through masonry, concrete or other
mineral rock types using annular coring bits.
Ø These drills are designed to be used by hand.
Ø These machines can be used vertically, horizontally or overhead (inverted) provided
an acceptable work environment.
o CAUTION: If drilling overhead you are only permitted to use dry type core bits
with a vacuum system. “Wet” type holes overhead would allow water into the
motor and create an extremely dangerous situation.
OPERATIONAL PRINCIPLES
Ø The main drilling shaft rotates in a forward clockwise direction. The main drilling
motor connects to the tool spindle to make contact with a surface and slowly bore a
hole.
Ø These drills are ONLY to be used with diamond impregnated coring bits.
o When drilling with “wet” type bits, the bit ends pulverizes the material and the
water brings the material out of the cut.
o When drilling with “dry” type bits, the bit end pulverizes the material and dust
brings the material out of the cut.
MACHINE COMPONENTS
Ø The main components of the GDC4 are the spindle, gearbox and motor. The spindle
is driven by the transfer case and the motor. There is a centrifugal clutch that
engages and drives the spindle once the motor begins to turn.

TRANSPORTING AND STORAGE OF THE MACHINE
Ø CAUTION: GAS FUMES ARE HIGLY FLAMABLE! GAS FUMES CAN CAUSE
DIZZINESS, VOMITING, AND A COMBUSTIBLE ENVIRONEMENT THAT CAN CAUSE
INJURY OR DEATH!
Ø When transporting the machine, always use two hands.
Ø DO NOT transport the machine with bits attached.
Ø As this is machine has a gas storage tank attached to the motor, it is NOT
recommended that this machine be transported inside of a vehicle. It is only
recommended to transport in a clean, dry, ventilated environment. ALWAYS secure
the machine when transporting with any vehicle so it does not move or bounce.
Ø The machine should be stored in a clean, dry, ventilated environment.
Ø “Winterizing” - It is recommended to run the machine dry (no gas in the fuel tank or in
the carburetor) if storing for more than 2 months as fuel can decay.
RUNNING THE MACHINE USING THE HANDHELD DRILLING METHOD
Ø Do all pre-operational and operational safety checks from Chapter 1.
Ø Consider your security and stability as well as the orientation of the machine in the
work area.
o DO NOT use this item in an unstable position (such as on a ladder, leaning
outside of center of gravity, etc). When using by hand, these drills could bind
up and personal injury could occur if not taking into account a very stable
body position.
o Consider the work surface material, condition, strength, density and rigidity.
These factors directly affect the tool’s efficiency.
Ø Ensure the work surface is free of debris, oil, etc.
Ø If using “wet” type bits, set up your drilling templates or other professional methods
for starting your hole.
Ø Select and set up fluid delivery method or dust collection system.
Ø If using the machine with the water system, connect hose to the side of the machine
using the connector.
o This connector takes standard ¾” US garden hose or quick disconnect
hookup depending on the model.
o Make sure the water valve is in the off position.
§ This is generally at a 90 degree angle from the valve hose.
o Partially turn the water spigot on (usually half a turn).
§ CAUTION: DO NOT turn the hose on fully! You need sufficient water
when using wet type bits. Using too much water pressure can cause
the bits to not cut properly as well as water entering the gearbox.
