1. KNOW YOUR TOOL

Read and understand the owners manual and labels affixed to the tool. Learn its

application and limitations as well as its specific potential hazards.

2. DON’T USE power tools in damp or wet locations or expose them to rain. Keep work

area well lit and provide adequate surrounding work space.

3. USE RIGHT TOOL.

Don’t force the tool or the attachment to do a job for which it was not designed.

4. WEAR PROPER APPAREL.

Do not wear loose clothing, gloves, neckties or jewelry (rings, watch) because they could

get caught in moving parts. Non-slip footwear is recommended. Wear protective hair

covering to contain long hair. Roll up long sleeves above the elbows.

5. MAINTAIN TOOL WITH CARE.

Keep tool clean for best and safest performance. Follow instructions for operation and

changing accessories.

6. DISCONNECT TOOLS.

Before servicing, when changing accessories or attachments.

7. AVOID ACCIDENTAL STARTING.

Make sure the switch is in the ‘’OFF’’ position before plugging in.

8. USE RECOMMENDED ACCESSORIES.

Consult the manual for recommended accessories. Follow the instructions that

accompany the accessories. The use of improper accessories may cause hazards.

9. CHECK FOR DAMAGED PARTS.

Before further use of the tool, a guard or other parts that are damaged should be

carefully checked to ensure they will operate properly and perform their intended

function. Check for alignment of moving parts, breakage of parts, mounting, and any

other conditions that may affect its operation. A guard or other parts which are damaged

should be properly repaired or replaced.

SPECIFIC RULES FOR SAFE OPERATION

1. Use specified grinding wheel: The wheel used by the grinder must be reinforced fibre

resin, with a safety linear velocity not lower than 80 meters per second. If the wheel

has been kept for more than one year, a rotational strength test should be performed

before use.

2. Pay attention to the wheel guard: This wheel guard is an important part of the tool to

ensure safety. Do not operate the tool when the wheel guard has been dismantled.

3. Places prohibiting the use of the tool: The tool must not be used in specific

environements such as environements with moisture, heat, rain or snow or in a place

with explosive gas or corrosive vapours.

4. Unplugging the tool: The tool should be unplugged after each use or before servicing

(changing parts or wheel). Do not unplug the tool by pulling on the power cord.

5. Prevent the tool from starting unexpectedly: Before putting the plug into a socket, make

sure the switch is in the OFF position. When the plug is still connected to the power

source, do not carry the tool with your finger pressing on the trigger of the switch.

ELECTRICAL INFORMATION

WARNING: The warnings, cautions, and instructions discussed in this instruction manual

cannot cover all possible conditions and situations that may occur. It must be understood

by the operator that common sense and caution are factors which cannot be built into this

product, but must be supplied by the operator. Performance of this tool may vary

depending on variations in local line voltage. Extension cord usage may also affect tool

performance.

VOLTAGE WARNING

Before connecting the tool to a power source (receptacle, outlet, ect.) be sure the voltage

supplied is the same as that specified on the nameplate of the tool. If one says 120V and

the other says 115V then there will be no complications. Never try to plug a 120V tool into

a 240V outlet, or the other way around. A voltage greater than that specified on the tool

can result in SERIOUSINJURY to the user, as well as damage to the tool. If in doubt, DO

NOTPLUGINTHETOOL.

WARNING: YOUR ANGLE GRINDER MUST BE CONNECTED TO A 120V, 15-AMP,

BRANCH CIRCUIT BREAKER. FAILURE TO CONNECT IN THIS WAY CAN RESULT IN

INJURY FROM SHOCK OR FIRE.

DOUBLE INSULATION

Double insulated tools are equipped with a polarized

two-prong plug (one blade is wider than the other).

This plug will fit in a polarized outlet only one way. If

the plug does not fit fully into the outlet, reverse the

plug. If it still does not fit, contact a qualified

electrician to install a polarized outlet. Do not alter or

change the plug in any way. Double insulation

eliminates the need for three wire grounded power

supply and grounded power cords.

EXTENSION CORDS

Improper use of extension cords may cause

inefficient operation of your tool which can result

in overheating. Be sure your extension cord is

rated to allow sufficient current flow to the motor.

If you are using the tool outdoors, use an

extension cord rated for outdoor use (signified

by “WA” on the jacket).

The extension cord must have a minimum wire size depending on the amperage of the

tool and the length of the extension cord. This size is determined by its AWG (American

Wire Gauge) rating. The smaller the gauge, the greater the cable’s capacity. The amount

of cords used does not matter: Total length determines the minimum AWG rating. Every

cord must meet the AWG rating. Use the chart in Fig.2 to determine what AWG rating is

required for your situation.

INSTALLING HANDLE & GRINDING WHEEL

1) Install the handle (A) Fig.3 on either side of the

motor housing, based on the application or if you

are right or left handed.

2) Press and hold down the spindle lock button (B)

Fig.3.

3) Remove the outer flange (A) Fig.4 with the

included spanner wrench (A) Fig.5 by turning

counterclockwise.

4) Install grinding wheel (B) Fig.4 against the inner

flange (C).

5) Secure new grinding wheel with outer flange (A) by

pressing and holding spindle lock button and using

spanner key (A) Fig.5 to fix into place (clockwise).

6) If the safety guard (A) Fig.6 is not in the most

suitable position for the operation, it is

recommended to shift the position of the safety

guard by loosening the fixing screw (B), shift safety

guard position and secure the fixing screw.

Warning! If you wish to install a wire brush, the safety

guard must be removed. Reinstall safety guard once

the wire brush operation is finished.

OPERATION

1) To turn the power on, firmly hold the angle grinder

with one hand. Use the other hand to hold the side

handle. Push the on/off trigger (C) Fig.3 forward to

start the angle grinder.

2) Use the side handle to help steady the tool and

assist movement.

3) Different grinding angles produce different

finishes. For rough stock, grind at a 30º angle. For

finishing operations, grind at a 15º angle.

4) Do not use excessive force, let the grinding wheel

do most of the work.

5) Once the grinding operation is finished, push the

trigger backward to stop the grinder, wait until the

grinding wheel has come to a complete stop before

you put the tool down.

MAINTENANCE

INSPECTING/REPLACING CARBON BRUSHES

Remove and check the carbon brushes regularly

(normally after 50 hours of use). The carbon brushes

are installed inside the motor housing. Using a

screwdriver, remove the carbon brush caps (A) Fig.7

on both sides of the motor housing.

Remove the carbon brush (A) Fig.8 from the motor

housing and inspect it. Repeat this step for the

second carbon brush. Carbon brushes need to be

replaced once they wear down to the small limit mark

as shown in Fig.8. Keep the carbon brushes clean

and free to slip in the holders.

If they have worn down to the limit mark, purchase a

set of identical replacement carbon brushes (both

carbon brushes should be replaced at the same

time). Install new carbon brushes and reinstall the

carbon brush caps.

If you are unsure about these instructions, we

recommend that you get a qualified service technician to replace the carbon brushes.

Contact a King Canada service centre.

FREQUENT INSPECTION AND MAINTENANCE

The tool should be inspected and maintained frequently. Check and make sure the power

cord, internal wires, plug and switch are in good condition. Make sure the insulation

resistance is within normal limits, contact between the brushes and the commutator are

good, and that there is no short-circuit or breakage of the armature and stator windings.

Check the grinding wheel, bearings and driving parts also.

Grease the tool frequently. Grease can be volatilized and therefore the grease in the gear-

box should be kept clean, replenish or renew as needed.

Do not allow brake fluid, gasoline, petroleum-based products such as penetrating oils to

come in contact with plastic parts. They contain chemicals which can damage, weaken or

destroy the motor housing, thus compromising the intergrity of the double insulation.

Inspect mounting screws regularly, making sure they are properly tightened. Tighten all

loose screws before operating.

Service should be done by a qualified service technician using identical replacement parts.
