• Wear eye and hearing protection devices.
WARNING
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
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.
• 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-fueling
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.
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.
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.
WARNING
PRECAUTION AGAINST VIBRATION
AND COLD
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.
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.
Painful or numb fingers?
See your doctor
• 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.

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.
OPERATING TECHNIQUES
• When starting to drill, run the engine at full
throttle.
WARNING
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.
• 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.
• 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 unauthorized modification.
• 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.
