8. Do not use a damaged accessory. Before each

use inspect the accessory such as abrasive

wheels for chips and cracks, backing pad for

cracks, tear or excess wear, wire brush for

loose or cracked wires. If power tool or acces-

sory is dropped, inspect for damage or install

an undamaged accessory. After inspecting and

installing an accessory, position yourself and

accessory and run the power tool at maximum

11. Hold the power tool by insulated gripping

surfaces only, when performing an operation

where the cutting tool may contact hidden

wiring. Contact with a "live" wire will also make

exposed metal parts of the power tool "live" and

could give the operator an electric shock.

use auxiliary handle, if provided, for maximum

Important safety instructions for

battery cartridge

1. Before using battery cartridge, read all instruc-

tions and cautionary markings on (1) battery

charger, (2) battery, and (3) product using

battery.

2. Do not disassemble or tamper with the battery

cartridge.

3. If operating time has become excessively

shorter, stop operating immediately. It may

result in a risk of overheating, possible burns

and even an explosion.

4. If electrolyte gets into your eyes, rinse them

out with clear water and seek medical atten-

tion right away. It may result in loss of your

eyesight.

5. Do not short the battery cartridge:

(1) Do not touch the terminals with any con-

ductive material.

(2) Avoid storing battery cartridge in a con-

tainer with other metal objects such as

nails, coins, etc.

(3) Do not expose battery cartridge to water

or rain.

A battery short can cause a large current

Tips for maintaining maximum

battery life

1. Charge the battery cartridge before completely

discharged. Always stop tool operation and

charge the battery cartridge when you notice

less tool power.

2. Never recharge a fully charged battery car-

tridge. Overcharging shortens the battery

service life.

3. Charge the battery cartridge with room tem-

perature at 10 °C - 40 °C (50 °F - 104 °F). Let

a hot battery cartridge cool down before

charging it.

4. When not using the battery cartridge, remove

it from the tool or the charger.

5. Charge the battery cartridge if you do not use

it for a long period (more than six months).

OPERATION

WARNING: It should never be necessary to

force the tool. The weight of the tool applies ade-

quate pressure. Forcing and excessive pressure

could cause dangerous wheel breakage.

WARNING: ALWAYS replace wheel if tool is

dropped while grinding.

WARNING: NEVER hit the workpiece with the

wheel.

WARNING: Avoid bouncing and snagging

the wheel, especially when working corners,

sharp edges etc. This can cause loss of control and

kickback.

WARNING: NEVER use tool with wood cutting

blades and other saw blades. Such blades when
