CALIFORNIA PROPOSITION 65

It is important for you to read and understand this manual. The information it contains relates to protecting YOUR SAFETY and PREVENTING PROBLEMS. The symbols below are used to help you recognize this information.

SAFETY GUIDELINES - DEFINITIONS

Read all instructions. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury. The term "power tool" in all of the warnings listed below refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

SAVE THESE INSTRUCTIONS

1) Work area safety

a) Keep work area clean and well lit. Cluttered or dark areas invite

accidents.

b) Do not operate power tools in explosive atmospheres, such as in the

presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.

c) Keep children and bystanders away while operating a power tool.

Distractions can cause you to lose control.

2) Electrical safety a) Power tool plugs must match the outlet. Never modify the plug in any

way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric

shock.

b) Avoid body contact with earthed or grounded surfaces such as

pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.

c) Do not expose power tools to rain or wet conditions. Water entering a

power tool will increase the risk of electric shock.

d) Do not abuse the cord. Never use the cord for carrying, pulling or

unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk

of electric shock.

e) When operating a power tool outdoors, use an extension cord

suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.

3) Personal safety a) Stay alert, watch what you are doing and use common sense when

operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of

inattention while operating power tools may result in serious personal injury.

b) Use safety equipment. Always wear eye protection. Safety equipment

such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.

c) Avoid accidental starting. Ensure the switch is in the off-position

before plugging in. Carrying power tools with your finger on the switch or plugging in power tools that have the switch on invites accidents.

GENERAL SAFETY RULES

d) Remove any adjusting key or wrench before turning the power tool

on. A wrench or a key left attached to a rotating part of the power tool

may result in personal injury.

e) Do not overreach. Keep proper footing and balance at all times. This

enables better control of the power tool in unexpected situations.

f) Dress properly. Do not wear loose clothing or jewelry. Keep your

hair, clothing and gloves away from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts.

g) If devices are provided for the connection of dust extraction and

collection facilities, ensure these are connected and properly used.

Use of these devices can reduce dust-related hazards.

4) Power tool use and care a) Do not force the power tool. Use the correct power tool for your

application. The correct power tool will do the job better and safer at the

rate for which it was designed.

b) Do not use the power tool if the switch does not turn it on and off.

Any power tool that cannot be controlled with the switch is dangerous and must be repaired.

c) Disconnect the plug from the power source before making any

adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.

d) Store idle power tools out of the reach of children and do not allow

persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of

untrained users.

e) Maintain power tools. Check for misalignment or binding of moving

parts, breakage of parts and any other condition that may affect the power tools operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power

tools.

f) Keep cutting tools sharp and clean. Properly maintained cutting tools

with sharp cutting edges are less likely to bind and are easier to control.

g) Use the power tool, accessories and tool bits etc., in accordance

with these instructions and in the manner intended for the particular type of power tool, taking into account the working conditions and the work to be performed. Use of the power tool for

operations different from those intended could result in a hazardous situation.

5) Service a) Have your power tool serviced by a qualified repair person using only

identical replacement parts. This will ensure that the safety of the

power tool is maintained.

GENERAL SAFETY RULES

ADDITIONAL SPECIFIC SAFETY RULES

a) Keep hands away from cutting area and the blade. Keep your second

hand on auxiliary handle, or motor housing. If both hands are holding the

saw, they cannot be cut by the blade.

b) Do not reach underneath the workpiece. The guard cannot protect you

from the blade below the workpiece.

c) Adjust the cutting depth to the thickness of the workpiece. Less than a

full tooth of the blade teeth should be visible below the workpiece.

d) Never hold piece being cut in your hands or across your leg. Secure

the workpiece to a stable platform. It is important to support the work properly to minimize body exposure,blade binding, or loss of control.

e) Hold power tool by insulated gripping surfaces when performing an

operation where the cutting tool may contact hidden wiring or its own cord. Contact with a "live" wire will also make exposed metal parts of the

power tool "live" and shock the operator.

f) When ripping always use a rip fence or straight edge guide. This

improves the accuracy of cut and reduces the chance of blade binding.

g) Always use blades with correct size and shape (diamond versus round)

of arbor holes. Blades that do not match the mounting hardware of the saw will run eccentrically, causing loss of control.

h) Never use damaged or incorrect blade washers or bolt. The blade

washers and bolt were specially designed for your saw, for optimum performance and safety of operation.

Kickback Safety Instructions

Causes and Operator Prevention of Kickback: – Kickback is a sudden reaction to a pinched, bound or misaligned saw blade,

causing an uncontrolled saw to lift up and out of the workpiece toward the operator.

– When the blade is pinched or bound tightly by the kerf closing down, the

blade stalls and the motor reaction drives the unit rapidly back toward the operator.

– If the blade becomes twisted or misaligned in the cut, the teeth at the back

edge of the blade can dig into the top surface of the wood causing the blade to climb out of the kerf and jump back toward the operator.

Kickback is the result of saw misuse and/or incorrect operating procedures or

conditions and can be avoided by taking proper precautions as given below:

i) Maintain a firm grip with both hands on the saw and position your arms

to resist kickback forces. Position your body to either side of the blade, but not in line with the blade. Kickback could cause the saw to

jump backwards, but kickback forces can be controlled by the operator, if proper precautions are taken.

j) When blade is binding, or when interrupting a cut for any reason,

release the trigger and hold the saw motionless in the material until the blade comes to a complete stop. Never attempt to remove the saw from the work or pull the saw backward while the blade is in motion or kickback may occur. Investigate and take corrective actions to eliminate

the cause of blade binding.

k) When restarting a saw in the workpiece, centre the saw blade in the

kerf and check that saw teeth are not engaged into the material. If saw

blade is binding, it may walk up or kickback from the workpiece as the saw is restarted.

l) Support large panels to minimize the risk of blade pinching and

kickback. Large panels tend to sag under their own weight. Supports must be placed under the panel on both sides, near the line of cut and near the edge of the panel.

m)Do not use dull or damaged blades. Unsharpened or improperly set

blades produce narrow kerf causing excessive friction, blade binding and kickback.

n) Blade depth and bevel adjusting locking levers must be tight and

secure before making cut. If blade adjustment shifts while cutting, it may cause binding and kickback.

o) Use extra caution when making a "plunge cut" into existing walls or

other blind areas. The protruding blade may cut objects that can cause kickback.

Lower Guard Safety Instructions

p) Check lower guard for proper closing before each use. Do not

operate the saw if lower guard does not move freely and close instantly. Never clamp or tie the lower guard into the open position. If

saw is accidentally dropped, lower guard may be bent. Raise the lower guard with the retracting handle and make sure it moves freely and does not touch the blade or any other part, in all angles and depths of cut.

q) Check the operation of the lower guard spring. If the guard and the

spring are not operating properly, they must be serviced before use.

Lower guard may operate sluggishly due to damaged parts, gummy deposits, or a build-up of debris.

r) Lower guard should be retracted manually only for special cuts such

as "plunge cuts" and "compound cuts." Raise lower guard by retracting handle and as soon as blade enters the material, the lower guard must be released. For all other sawing, the lower guard should

operate automatically.

s) Always observe that the lower guard is covering the blade before

placing saw down on bench or floor. An unprotected, coasting blade will cause the saw to walk backwards, cutting whatever is in its path. Be aware of the time it takes for the blade to stop after switch is released.

Other Safety Instructions

t) Wear eye and hearing protection. Always use safety glasses.

Everyday eyeglasses are NOT safety glasses. USE CERTIFIED SAFETY EQUIPMENT. Eye protection equipment should comply with ANSI Z87.1 standards. Hearing equipment should comply with ANSI S3.19 standards.

u) Use of this tool can generate and disburse dust or

other airborne particles, including wood dust, crystalline silica dust and asbestos dust. Direct particles away from face and body. Always

operate tool in well ventilated area and provide for proper dust removal. Use dust collection system wherever possible. Exposure to the dust may cause serious and permanent respiratory or other injury, including silicosis (a serious lung disease), cancer, and death. Avoid breathing the dust, and avoid prolonged contact with dust. Allowing dust to get into your mouth or eyes, or lay on your skin may promote absorption of harmful material. Always use properly fitting NIOSH/OSHA approved respiratory protection appropriate for the dust exposure, and wash exposed areas with soap and water.

Fig. 13

CLAMP THE WORKPIECE

Secure the workpiece properly. The workpiece should be straight and firmly clamped to avoid possible movement and pinching as the cut nears completion. Provide adequate support for long or wide workpieces.

Confirm that the blade has come to a complete stop before removing or securing the workpiece, or changing the workpiece angle. Press the safety, then the trigger switch. Move the saw forward to contact the workpiece

Clamp the workpiece on a rigid support, such as a bench or saw horses. Mark the line of cut on the workpiece. Be sure that the cut-off line is far enough on the workpiece to allow proper operation of the telescoping guard. Place the front edge of the saw squarely on workpiece before starting the motor. Sight the cutting line with the sighting notch indicator or use the cutting guide. Be certain that the blade is not contacting the workpiece. Press the safety, then the trigger switch, and move the saw forward to begin the cut.

Keep the cord away from cutting area to prevent it from becoming entangled in the workpiece.

Do not force the saw. Let the saw do the cutting at the rate of speed permitted by the type of cut and workpiece to minimize sparking and to avoid overloading the tool. After completing the cut, release the power switch and wait for the coasting blade to stop completely before putting the saw down.
