ELECTRICAL SAFETY

WARNING: To avoid electrical hazards, fire hazards or damage to the

tool, use proper circuit protection.

This tool is wired at the factory for 120 V operation. It must be connected to

a 120 V, 15 A circuit that is protected by a time-delayed fuse or circuit

breaker. To avoid shock or fire, replace power cord immediately if it is worn,

cut or damaged in any way.

GENERAL SAFETY WARNINGS

WEAR A DUST MASK THAT IS DESIGNED TO BE USED WHEN

OPERATING A POWER TOOL IN A DUSTY ENVIRONMENT.

WARNING: Dust that is created by power sanding, sawing, grinding,

drilling, and other construction activities may contain chemicals that are known to cause cancer, birth defects, or other genetic abnormalities. These chemicals include:

Lead from lead-based paints Crystalline silica from bricks, cement, and other masonry products Arsenic and chromium from chemically treated lumber

The level of risk from exposure to these chemicals varies, according to how

often this type of work is performed. In order to reduce exposure to these

chemicals, work in a well-ventilated area, and use approved safety

equipment, such as a dust mask that is specifically designed to filter out

microscopic particles.

GENERAL SAFETY RULES

WARNING: Read and understand

all instructions. Failure to follow all

instructions listed below may result in

electric shock, fire and/or serious personal

injury.

WORK AREA

Keep your work area clean and well lit.

Cluttered benches and dark areas invite

accidents.

Do not operate power tools in potentially

explosive environments, such as in the

presence of flammable liquids, gas or dust.

Power tools create sparks that may ignite

dust or fumes.

Keep bystanders, children and visitors

away while operating the tool. Distractions

can cause the operator to lose control.

ELECTRICAL SAFETY

Double insulated tools are equipped with a

polarized plug (one blade is wider than the

other). This plug will only fit into a

polarized plug one way.

If the plug does not fit into the outlet

properly, reverse the plug. If it still does not

fit, contact a qualified electrician to install a

polarized outlet. Do not alter the plug in

any way. Double insulation eliminates the

need for the three-pronged grounded

power cord and grounded power supply

system.

Avoid contact between the operator's body

and grounded surfaces such as pipes,

radiators, ranges, and refrigerators. There

is an increased risk of electric shock if the

operator's body is grounded.

Do not expose power tools to rain or wet

conditions. Water entering the power tool

will increase the risk of electric shock.

Do not abuse the cord. Do not use the

power cord to carry the tool or to pull the

plug out of the outlet. Keep the power cord

away from heat, oil, sharp edges, and

moving parts. Replace a damaged power

cord immediately. A damaged power cord

increases the risk of electric shock.

When operating a power tool outdoors,

use an outdoor-rated extension cord type

“W-A” or “W”. These cords are rated for

outdoor use and they reduce the risk of

electric shock.

PERSONAL SAFETY

Stay alert, be aware of the surroundings,

and use common sense when operating a

power tool. Do not use a power tool while

tired or under the influence of drugs,

alcohol, or medication. A moment of

inattention while operating a power tool

may result in serious personal injury.

Dress properly. Do not wear loose clothing

or jewellery.

Contain long hair. Keep hair, clothing, and

gloves away from moving parts. Loose

clothing, jewellery, or long hair can get

caught in moving parts.

PERSONAL SAFETY – cont’d

Avoid accidental start-ups. Verify that the

switch is in the OFF position before

plugging in the tool. Carrying a power tool

with a finger on the switch or plugging in a

tool that has the switch in the ON position

invites accidents.

Remove adjusting keys and wrenches

before turning the tool ON. A wrench or

key that is left attached to a rotating part of

the tool may result in personal injury.

Do not overreach. Keep proper footing and

balance at all times. Proper footing and

balance allows the operator to maintain

better control of the tool in unexpected

situations.

Use safety equipment. Always wear eye

protection.

Use a dust mask, non-skid safety shoes, a

hardhat, or hearing protection when

appropriate.

USE AND CARE OF POWER TOOLS

Use clamps or another practical means to

secure and support the workpiece to a

stable platform. Holding the work in a hand

or against the body is not stable, and may

lead to loss of control.

Do not force the tool. Use the correct tool

for the application. The correct tool will do

the job better and safer when used at the

rate that it was designed to work at.

Do not use a power tool if it cannot be

turned ON or OFF using the power switch.

A tool that cannot be controlled using the

switch is dangerous, and must be repaired.

Disconnect the plug from the outlet before

making any adjustments, changing

accessories, or storing the tool. Such

preventive safety measures reduce the risk

of accidental start-ups.

When power tools are not in use, store

them out of the reach of children or

untrained persons. Tools are dangerous in

the hands of untrained users.

Maintain tools with care. Keep cutting tools

sharp and clean. Properly maintained

cutting tools with sharp cutting edges are

less likely to bind, and are easier to

control.

Inspect the tool for misalignment or binding

of moving parts, broken parts, and any

other condition that may affect the

operation of the tool. If it is damaged, have

the tool serviced before using it. Many

accidents are caused by poorly maintained

tools.

Use only accessories that are

recommended by the manufacturer for this

model. Accessories that are suitable for

one tool may become hazardous when

used with another tool.

SERVICE

Tool servicing must be performed by

qualified personnel. Service or

maintenance performed by non-qualified

personnel could result in a risk of injury.

SERVICE – cont’d

When servicing a tool, use only identical

replacement parts. Follow the instructions

in the Maintenance section of this Manual.

The use of unauthorized parts or failure to

follow the instructions in the Maintenance

section of this Manual may create a risk of

electric shock or injury.

WARNING: Know your cordless

angle grinder. Do not plug in the

charger or install a battery in the tool

until you have read and understand this

Instruction Manual. Learn the tool’s

applications and limitations, as well as

the specific potential hazards related to

this tool. Following this rule will reduce the

risk of electric shock, fire, or serious injury.

Always wear eye protection. Any power

tool can throw foreign objects

into your eyes and cause

permanent eye damage.

ALWAYS wear safety goggles

(not glasses) that comply with ANSI safety

standard Z87.1. Everyday glasses have

only impact resistant lenses. They ARE

NOT safety glasses.

WARNING: Glasses or goggles

not in compliance with ANSI Z87.1

could cause serious injury when they

break.

WARNING: Always wear gloves to

protect your hands from hot sparks.

WARNING: Always wear hearing

protection and a dust mask. Use only in

well ventilated areas. Use of personal

protective equipment and working in a safe

environment will reduce the risk of injury.

Always keep hands out of the path of the

grinding disc. Avoid awkward hand

positions where a sudden slip could cause

your hand to move into the rotating disc.

To avoid injury from accidental starting,

always remove the battery from the angle

grinder before installing or removing

grinding discs.

The grinding disc and guard must be

securely attached as described in this

Owner’s Manual before installing a battery

in the tool. Failure to do so will increase

the risk of serious injury if the grinding disc

shatters.

Make sure the guard is in good condition

and securely installed before operating

grinder.

Secure the workpiece. Use clamps or a

vice to hold the work when practical. It’s

safer than using your hand and it frees

both hands to operate the tool.

ground at an acute angle, normally

between 5° and 15° (Fig. 11).

For maximum control, hold the grinder in

front and away from you with both hands,

keeping the grinding disc clear of the

workpiece. Start your grinder and let the

motor and grinding disc build up to full

speed. Gradually lower the grinder until the

grinding disc contacts the workpiece

For best results keep the grinder tilted at

an angle of between 5° and 15° and

continuously moving at a steady,

consistent pace. Move the grinder back

and forth or up and down over the work

area. Keep the grinder moving so that an

excessive amount of material is not

removed from one area. If the grinder is

held in one spot too long, it will gouge and

cut grooves in the workpiece. If the grinder

is held at too sharp an angle, it will gouge

the workpiece because of the

concentration of pressure on a small area.

GRINDING – cont’d

Use just enough pressure to keep the

grinder from chattering or bouncing. Heavy

pressure will decrease its speed and put a

strain on the motor. Normally, the weight of

the tool alone is adequate for most

grinding jobs. Use light pressure when

grinding jagged edges or loose bolts where

there is potential for the grinder to snag on

the metal edge.

Lift the grinder away from the workpiece

before turning it OFF.

WARNING: When servicing, use

only identical replacement parts. Use of

any other part may create a hazard or

cause product damage.

DO NOT abuse power tools. Abusive

practices can damage the tool as well as

the workpiece.

WARNING: DO NOT attempt to

modify tools or create accessories. Any

such alteration or modification is misuse

and could result in a hazardous condition

leading to possible serious injury. It will

also void the warranty.

CLEANING

DO NOT use solvents when cleaning

plastic parts. Most plastics are susceptible

to damage from various types of

commercial solvents and may be damaged

by their use. Use a clean cloth to remove

dirt, dust, oil, grease, etc.

WARNING: Do not at any time

allow brake fluids, gasoline, petroleum-

based products, penetrating oils, etc. to

come in contact with plastic parts. They

contain chemicals that can damage,

weaken or destroy plastic.

WARNING: Always wear safety

goggles or safety glasses with side shields

during all grinding operations. It is critical

that you also wear safety goggles or safety

glasses with side shields and a dust mask

while blowing dust out of the angle grinder

with an air jet. Failure to take these safety

precautions could result in permanent eye

or lung damage.

LUBRICATION

All of the bearings in this angle grinder are

lubricated with a sufficient amount of high-

grade lubricant for the life of the unit under

normal conditions. Therefore, no further

lubrication is required.
