WARNING
Some dust created by power sanding, sawing, grinding, drilling, and
other construction activities contains chemicals known to the State of
California to cause cancer, birth defects or other reproductive harm.
Some examples of these chemicals are:
• Lead from lead-based paints,
• Crystalline silica from bricks and cement and other masonry
products, and
• Arsenic and chromium from chemically treated lumber.
Your risk from these exposures varies, depending on how often you do
this type of work. To reduce your exposure to these chemicals: work in a
well ventilated area, and work with approved safety equipment, such as
those dust masks that are specially designed to filter out microscopic
particles.
WARNING
The engine exhaust from this
product contains chemicals known
to the State of California to cause
cancer, birth defects or other
reproductive harm.

WARNING DANGER
ALWAYS STOP THE ENGINE WHEN A DRILL
JAM OCCURS. DO NOT ATTEMPT TO
REMOVE AN OBJECT CAUSING A DRILL
JAM IF THE ENGINE IS RUNNING. PHYSICAL
INJURY CAN OCCUR IF A DRILL JAM IS
REMOVED AND THE DRILLS START
MOVING.
• Do all drilling at full throttle speed. Drilling at
less at than full speed can damage the clutch
by allowing it to slip.
WARNING DANGER
USE A FIRM GRIP WITH THUMBS AND
FINGERS ENCIRCLING THE HANDLES. A
FIRM GRIP WILL HELP YOU KEEP CONTROL
OF THE ENGINE DRILL. NEVER OPERATE
THE ENGINE DRILL ONLY ONE HAND OR
BODILY INJURY CAN OCCUR.
• Always carry the engine drill with the engine
stopped and the HOT muffler away from your
body.
PROTECTIVE EQUIPMENT
• Always wear eye protection goggles that meet
ANSI Z87.1 standards.
• Wear hearing protection.
ECHO recommends that hearing protection be
worn at all times.
• Dress properly! Do not wear loose clothing or
jewellery, they can be caught in moving parts.
Use of sturdy gloves, non-skid footwear, and
safety glasses is recommended.
• While operating the machine always be sure of
a secure position.
WARNING DANGER
ENGINE DRILL USERS RISK INJURY TO
THEMSELVES AND OTHERS IF THE ENGINE
DRILL IS USED IMPROPERLY, AND/OR
SAFETY PRECAUTIONS ARE NOT
FOLLOWED. PROPER CLOTHING AND
SAFETY GEAR MUST BE WORN WHEN
OPERATING ENGINE DRILL.
OPERATOR SAFETY
• Read this Engine drill Operator’s Manual
carefully. Be sure you understand how to
operate this unit properly before you use it.
• Be familiar with all the controls and the proper
use of the machine.
• Wear proper clothing to protect legs and other
exposed parts of your body.
• Wear non-skid sole shoes. Do not wear open-
toed shoes or operate unit while bare footed.
• Wear eye and hearing protection devices.
• Use caution when handling fuel. Put the caps
back tightly on both the fuel can and the engine
drill fuel tank.
Move at least 3 m (10 feet) from the re-fuelling
point and be sure there is no leakage of fuel
from the fuel tank cap or the fuel system before
starting the engine.
• Operate this gasoline powered engine
equipment in a well-ventilated area only.
• Start the unit on the ground with the throttle set
at idle. Do not start if the drills are obstructed
by the ground or any other object.
• Never allow children to use the machine.
• Do not allow anyone to hold the material you
are drilling.
• Keep a firm grip on the engine drill with both
hands, one hand on the front handle, the other
hand on the rear handle.
SAFETY

3
• Wear non-slip, heavy-duty work gloves to
improve your grip on the engine drill handles.
The gloves also help reduce the transmission
of machine vibrations to your hands.
PROTECTING OTHERS
Spectators, children, fellow workers and animals
must be warned to come no nearer than 4.6 m (15
feet) while the engine drill is in use.
People working in the area near you should wear
the same protective equipment as the operator.
PHYSICAL CONDITION
Your judgement and dexterity may be impaired if
you are ill or have taken alcohol or other
substances known to affect the way you would
normally function.
WARNING DANGER
PRECAUTION AGAINST VIBRATION
AND COLD
IT IS BELIEVED THAT A CONDITION CALLED
RAYNAUD’S PHENOMENON, WHICH
AFFECTS THE FINGERS OF CERTAIN
INDIVIDUALS MAY BE BROUGHT ABOUT BY
EXPOSURE TO VIBRATION AND COLD.
EXPOSURE TO VIBRATION AND COLD MAY
CAUSE TINGLING AND BURNING
SENSATIONS FOLLOWED BY LOSS OF
COLOR AND NUMBNESS IN THE FINGERS.
THE FOLLOWING PRECAUTIONS ARE
STRONGLY RECOMMENDED BECAUSE THE
MINIMUM EXPOSURE WHICH MIGHT
TRIGGER THE AILMENT IS UNKNOWN.
• KEEP YOUR BODY WARM, ESPECIALLY
THE HEAD, NECK, FEET, ANKLES, HANDS
AND WRISTS.
• MAINTAIN GOOD BLOOD CIRCULATION
BY PERFORMING VIGOROUS ARM
EXERCISES DURING FREQUENT WORK
BREAKS AND ALSO BY NOT SMOKING.
• LIMIT THE HOURS OF OPERATION. TRY
TO FILL EACH DAY WITH JOBS WHERE
OPERATING THE ENGINE DRILL OR
OTHER HAND-HELD POWER EQUIPMENT
IS NOT REQUIRED.
• IF YOU EXPERIENCE DISCOMFORT,
REDNESS AND SWELLING OF THE
FINGERS FOLLOWED BY WHITENING AND
LOSS OF FEELING, CONSULT YOUR
PHYSICIAN BEFORE FURTHER EXPOSING
YOURSELF TO COLD AND VIBRATION.
Painful or numb fingers?
See your doctor

Repetitive Stress Injuries
It is believed that over-using the muscles and
tendons of the fingers, hands, arms and shoulders
may cause soreness, swelling, numbness,
weakness and extreme pain in those areas.
Certain repetitive hand activities may put you at a
high risk for developing a Repetitive Stress Injury
(RSI). An extreme RSI condition is Carpal Tunnel
Syndrome (CTS), which could occur when your
wrist swells and squeezes a vital nerve that runs
through the area. Some believe that prolonged
exposure to vibration may contribute to CTS.
CTS can cause severe pain for months or even
years. To reduce the risk of RSI/CTS, do the
following:
• Avoid using your wrist in a bent, extended or
twisted position. Instead try to maintain a
straight wrist position. Also, when grasping, use
your whole hand, not just the thumb and index
finger.
• Take periodic breaks to minimize repetition and
rest your hands.
• Reduce the speed and force with which you do
the repetitive movement.
• Do exercise to strengthen the hand and arm
muscles.
• See a doctor if you feel tingling, numbness or
pain in the fingers, hands, wrists or arms.
The sooner RSI/CTS is diagnosed, the more
likely permanent nerve and muscle damage
can be prevented.

WARNING DANGER
BEFORE DRILLING, BE SURE TO READ AND
UNDERSTAND THE ENTIRE OPERATOR’S
MANUAL TO AVOID THE CHANCE OF
SERIOUS INJURY.
• Do not force the drills and only move as quickly
as the drills will allow.
• Stop the engine and disconnect from ignition
cable before: - cleaning or when clearing a
blockage; checking, maintenance or working on
the machine.
• Handle fuel with care; it is highly flammable.
Never add fuel to a machine with a running or
hot engine.
• Do not attempt to repair the machine unless
you are qualified to do so.
• Do not operate the machine with a damaged or
excessively worn drill bit.
• Always ensure all handles and guards are fitted
when using the machine. Never attempt to use
an incomplete machine or one fitted with an
unauthorizedmodification.
• When starting to drill, run the engine at full
throttle. • When transporting or storing the machine always remove the drill bit.
• To reduce fire hazard keep engine and silencer
free of debris, leaves or excessive grease.
• Handle drill with care, contacting with drills may
cause injury.

REVERSE ROTATION
• This model is equipped with reverse rotation
mechanism.
• When drilling, set shift lever down to clockwise
(CW) rotation position.
• If bit is locked due to deep penetration during
drilling operation, set shift lever up to
counterclockwise (CCW) rotation position and
operate reversed for easy pulling-out.
• When changing direction of drill rotation,
operate as follows:
- Return engine to idle.
- Engine shift lever to CW or CCW position
with a slight acceleration of the throttle
trigger.
To properly lock the gears in the gear case.
- Do not operate shift lever forcibly when
changing rotation direction.
NOTE
When engine does not stop, shift choke lever to
close position.
Check and repair ignition switch before starting
the engine again.
STOPPING ENGINE
• Set throttle trigger in idle position.
• Place ignition switch in STOP position.
STARTING WARM ENGINE
• Place ignition switch in ON (START/RUN)
position.
• Pull starter handle until the engine fires.
- Do not use the choke.
NOTE
