Echo EDR-2100 User Manual

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.

SAFETY

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.

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.

• 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 re­fuelling 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, the right hand on the front handle,
the left 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.

2

• 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.

EXTENDED OPERATION/
EXTREME CONDITIONS

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.

3

Repetitive Stress Injuries

It is believed that overusing 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 activites
may put you at a high risk for developing a
Repetitives 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.

4

OPERA TING TECHNIQUES

• When starting to drill, run the engine at full
throttle.

• When transporting or storing the machine
always remove the drill.

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 cutting
device.

• 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.

• Always ensure all handles and guards are
fitted when using the machine. Never
attempt to use an incomplete machine or
one fitted with an unauthorised
modification.

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 gears
in the gear case.

- Do not operate shift lever forcibly when

changing rotation direction.

NOTE

Do not shift from forward to reverse (or
vice-versa) while the chuck is turning.
Failure to do so may cause unit damage.
Always release throttle and allow the unit to
return to idle before shifting.

Do not stand close to drill or chuck with
your body or clothes while operation.

When drilling, ensure that no power cable
or other obstacle exist.

WARNING DANGER

• WHEN THE DRILL CAN NOT PULL OUT
FROM THE WOOD, DO NOT TRY TO
PULL OUT THE DRILL BY FORCE.

• WHEN CHANGING THE BIT, ENSURE
TO STOP THE ENGINE.

• AFTER A JOB, BIT AND GEAR CASING
MAY BE HEATED, DO NOT TOUCH
THEM WITH BARE HANDS.
