Safety Instructions and Warnings for Chain Saws

• Keep Work Area Clean

Cluttered areas invite injuries. Do not start cutting until y have a clear work area, secure footing, and a planned retre path from the falling tree.

• Consider Work Area Environment

Use extreme caution when cutting small size brush a saplings because the slender material may catch the sa chain and be whipped toward you or pull you off balance. not operate a chain saw in a tree unless specifically trained do so. When cutting a limb that is under tension be alert spring back so that you will not be struck when the tension the wood fibers is released. Do not expose chain saw to ra Do not use chain saw in damp or wet locations.

Do not use chain saw in the presence of flammable liquids gases or enclosed concentrations of dust.

• Guard Against Electric Shock

Prevent body contact with grounded surfaces. For examp metal pipes, wire fences.

safety precautions when operating this tool. The insulation system is for added protection against injury resulting from a possible electrical insulation failure within the tool.

REPLACEMENT PARTS: When servicing all tools, USE IDENTICAL REPLACEMENT PARTS. Repair or replace damaged cords.

Safety Instructions: Polarized Plugs

To reduce the risk of electric shock, this equipment has a polarized plug (one blade is wider than the other). This equipment must be used with a suitable polarized 2 wire or 3 wire extension cord. Polarized connections will fit together only one way. Make sure that the receptacle end of the extension cord has large and small blade slot widths. If the plug does not fit fully into the extension cord, reverse the plug. If it still does not fit, obtain a suitable extension cord. If the extension cord does not fit fully into the outlet, contact a qualified electrician to install the proper outlet. Do not change the tool plug or extension cord in any way .

WARNING:T o reduce the risk of electric shock use only with an extension cord intended for outdoor use, such as SW-A, S0W-A, STW-A, STOW-A, SJW-A, SJOW-A, SJTW-A or SJTOW-A.

Extension Cord

Make sure your extension cord is in good condition. When using an extension cord be sure it is heavy enough to carry the current your product will draw. An undersized extension cord will cause a drop in line voltage resulting in loss of power and overheating. The following table shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the gage number, the heavier the cord.

• Keep Children Away

Do not let visitors contact chain saw or extension cord. All visitors should be kept away from work area.

• Store Idle Chain Saw

When not in use, chain saws should be stored in a dry, and high or locked-up place - out of the reach of children. When storing saw, use a scabbard or carrying case.

• Don't Force Chain Saw

It will do the job better and safer at the rate for which it was intended.

• Use Right T ool

Cut wood only. Don't use chain saw for purpose not intended for example - Don't use chain saw for cutting plastic, metal, masonry , non-wood building materials.

• Dress Properly

Do not wear loose clothing or jewelry. They can get caught in moving parts. Rubber gloves and non-skid footwear are recommended when working outdoors. Wear protective hair covering to contain long hair.

• Use Safety Glasses

Also use safety footwear; snug fitting clothing; protective gloves; hearing and head protection.

• Carrying Saw

Carry the chain saw by the front handle with the saw stopped, finger off the switch, the guide bar and saw chain to the rear. Use scabbard when transporting saw.

• Maintain Chain Saw With Care

any obstruction that your saw chain could hit while you ar cutting through a particular log or branch.

(10.) Keep your saw chain sharp and properly tensioned. A loose or dull chain can increase the chance of kickback Check tension at regular intervals with the motor stopped never with the motor running.

(1 1.) Begin and continue cutting only with the chain moving a full speed. If the chain is moving at a slower speed, there is greater chance for kickback to occur.

(12.) Cut one log at a time. (13.) Use extreme caution when re-entering a previous c

Engage spiked bumpers into wood and allow chain to reach f speed before proceeding with cut.

(14.) Do not attempt plunge cuts or bore cuts. (15.) Watch for shifting logs or other forces that could close

cut and pinch or fall into chain.

• Power Supply

Connect chain saw to correct voltage, that is, be sure that t voltage supplied is the same as that specified on th nameplate of the tool.

Kickback Safety Features

Warning: The following features are included on your sa

to help reduce the hazard of kickback; however such featur will not totally eliminate this dangerous reaction. As a cha saw user do not rely only on safety devices. You must follo all safety precautions, instructions, and maintenance in th manual to help avoid kickback and other forces which c result in serious injury.

• Reduced-Kickback Guide Bar, designed with a sm radius tip which reduces the size of the kickback danger zo on bar tip. A reduced- kickback guide bar is one which h

assembled. Be sure that the saw chain stops moving when the trigger is released.

• Guard Against Kickback WARNING: KICKBACK may occur when the nose or tip of

the guide bar touches an object, or when the wood closes in and pinches the saw chain in the cut. Tip contact in some cases may cause a lightning fast reverse reaction, kicking the guide bar up and back towards the operator. Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back towards the operator. Either of these reactions may cause you to lose control of the saw which could result in serious injury to user.

The following precautions should be followed to minimize kickback:

(1.) Grip Saw Firmly . Hold the chain saw firmly with both hands when the motor is

running. Use a firm grip with thumbs and fingers encircling the chain saw handles.

(2.) Do not over reach. (3.) Keep proper footing and balance at all times. (4.) Don't let the nose of the guide bar contact a log, branch,

ground or other obstruction. (5.) Don't cut above shoulder height. (6.) Use devices such as low kickback chain, chain braking

system and special guide bars that reduce the risks associated with kickback.

(7.) Only use replacement bars and chains specified by the manufacturer or the equivalent.

(8.) Never let the moving chain contact any object at the tip of the guide bar.

(9.) Keep the working area free from obstructions such as other trees, branches, rocks, fences, stumps, etc. Eliminate or avoid

on wet or slippery surfaces, or during snow storms, ra storms, or other adverse weather conditions.

• Keep the handles dry , clean, and free of oil or grease.

• Do not allow dirt, debris, or sawdust to build up on the mo

or outside air vents

SAVE THESE INSTRUCTIONS

Preparing Your Chain Saw for Use

Chain oiling

• Chain oiling is recommended whenever you use a new chain the first time. Take the new chain and soak it in chain oil for least an hour before using it.

• Oiling during use is automatic and is not adjustable.

• We recommend that you use only one brand of oil during t

lifetime of your chain saw because mixtures of different o could lead to the oil becoming degraded, which can drastica shorten the lifetime of the saw chain.

• Never use waste oil, thick oil or very thin sewing machine These may damage your chain saw.

Assembly of guide bar and chain (Fig. C)

Warning: Always unplug the saw from the power sour

before installing a bar and/or a chain.

Caution: Always wear protective gloves when working on

your chain saw. The chain is sharp and can cut you when it

not running.

• (Fig. C1) Fit the saw chain (1) over the guide bar (2), mak sure that the cutters are facing the right way and that the slid tensioner (16) is facing towards you.

• (Fig. C2) Remove the chain tensioner knob (4) and the cov screw located just below it. With your chain saw horizontal on

been demonstrated to significantly reduce the number and seriousness of kickbacks when tested in accordance with safety requirements for electric chain saws.

• Low-Kickback Chain, designed with a contoured depth gauge and guard link which deflect kickback force and allow wood to gradually ride into the cutter. A low-kickback chain is a chain which has met kickback performance requirements of ANSI B175.1-1991.

• Hand guard, designed to reduce the chance of your left hand contacting the chain if your hand slips off the front handlebar.

• Position of front and rear handlebars, designed with distance between handles which provides better control, balance, and resistance if kickback occurs.

Additional Safety Rules: Chain Saws

CAUTION: Some wood contains preservatives such as

copper chromium arsenate (CCA) which can be toxic. When cutting these materials extra care should be taken to avoid inhalation and minimize skin contact.

WARNING: Use of this tool can generate dust containing chemicals known to cause cancer, birth defects or other reproductive harm. Use appropriate respiratory protection.

• Do not operate chain saw that is damaged, improperly adjusted, or not completely and securely assembled. Be sure that the saw chain stops moving when the trigger is released.

• Do not attempt operations beyond your capacity or experience.

• Do not operate a chain saw with one hand! Serious injury to the operator, helpers, or bystanders may result from onehanded operation. A chain saw is intended for two-handed use only .

• To reduce potential for electric shock, do not operate the saw

chainsaw booklet 1/19/00 1:45 PM Page 10

Oiling (Fig. D)

• (Fig. D) Fill the reservoir via the oil filler cap (8) with standar chain saw oil. If chain saw oil is not available SAE#30 motor o can be substituted. Note: For temperatures below 30°F, u s SAE#10 oil. For temperatures above 75°F, use SAE#40 o The level of oil is checked through the oil level indicator slot (7

• Periodically switch off and check the oil in the indicator; if it

less than a quarter full, disconnect your chain saw from th power supply and refill with the correct oil.

Auto-Stop Chain Braking System (Fig. E)

Your chain saw is fitted with an auto-stop chain braking system wh will stop the chain within a fraction of a second each time you relea the rear trigger, or if kickback should occur. This system should tested before every use.

How to set your auto stop hand guard

•Ensure that your chain saw is disconnected from the power supp

•(Fig. E1) Pull the front guard (9) back into the "set"

position .Your chain saw is now ready to use.

How the anti-kickback chain braking system works

In the event of kickback, your left hand comes in contact with the fro guard, pushing it forward and stops your chain saw within a f fractions of a second.

How the inertia activated chain braking system works

The brake is activated when the front hand guard is pushed forwa either manually, by the back of the user’s hand or by its own weig The advantage of the inertia brake is that it is activated by a seve kickback, eg. when the chain hits metal, even if the user’s hand do not contact the hand guard, ie. when the saw is in the felling positio

How to test the anti-kickback chain braking system

• Grip your chain saw firmly in both hands on a firm surfac

stable surface, put the bar and chain onto the bar mounting studs (12), ensuring the chain is around the drive sprocket (13). Ensure that the cutters are pointing in the same direction as the embossed graphic (13a) above and below the drive sprocket (13).

• (Fig. C3) Before fitting the chain cover check that the cam (17) is in the correct position. The flat section of the metal cam should be visible through the opening in the chain cover. If necessary, press and turn the control knob (4) clockwise to rotate the cam into the correct position.

• (Fig. C4) Fit the chain cover by locating the bolt and using the control knob (4) to tighten the chain cover finger tight. To tension the chain, loosen the control knob (4) one full turn, press in firmly and rotate clockwise. As the bar moves forward ensure the chain links feed into the guide bar. When the control knob stops rotating, apply further light pressure. Do not over- tension. Allow the control knob to spring back to the "out" position and rotate further clockwise to tighten the guide bar. Apply moderate pressure to tighten. Replace the cover screw.

• (Fig. C5/C6) Check the chain tension by placing the saw on a firm surface. The tension is correct when the chain snaps back after being pulled 1/8" (3mm) away from the chain bar with light force from the middle finger and thumb. There should be no "sag" between the guide bar and chain on the underside as shown in Fig.C5. Fig C6 illustrates a sagging improperly tensioned chain.

Note: Do not over-tension the chain as this will lead to excessive wear and will reduce the life of the bar and chain.

Note: When the chain is new check the tension frequently (after disconnecting from power supply) during the first 2 hours of use as a new chain stretches slightly.

Switch

• (Fig. G1) Always be sure of your footing and grip the chain sa handles firmly with both hands with the thumb and finge encircling the handle. Push the lock-off button (10) forward a then pull the trigger (11) to start as shown in Figure G2. To sto release the trigger.

• When the motor starts remove your thumb from the lock butt and grip the handle firmly.

Do not force your chain saw It will do a better and safer job at t speed for which it is designed. Excessive force will stretch the chai

If the saw chain or bar becomes jammed:

• Switch off.

• Disconnect from the power supply.

• Open the cut with wedges to relieve the strain on the guide b

Do not try to wrench the saw free. Start a fresh cut.

COMMON CUTTING TECHNIQUES Felling (Fig. H)

• Felling is the process of cutting down a tree. Bucking is t process of cutting a log into lengths. When bucking and felli operations are being performed by two or more persons, at t same time, the felling operation should be separated from t bucking operation by a distance of at least twice the height the tree being felled. Trees should not be felled in a manner th would endanger any person, strike any utility line or cause a property damage. If the tree does make contact with any uti line, the utility company should be notified immediate Scrutinize the surrounding overhead for dead or broken limbs branches which may fall during the felling process.

The chain saw operator should keep on the uphill side of t terrain as the tree is likely to roll or slide downhill after it is felle

• (Fig. H1) A retreat path should be planned and cleared

If you have any questions, call 1-800-54-HOW-TO

make sure the chain is clear of the ground and switch on (see "Using Your Chain Saw").

• (Fig. E2)Rotate your left hand forward around the front handle so that the back of your hand comes in contact with the front guard and pushes it forward. The chain should stop within a few fractions of a second.

To reset after the operation of the chain braking system

Follow the instructions for setting the chain braking system.

Notes:

• It will not be possible to switch on your chain saw if the front guard/chain brake is not in the "set" position .

• Avoid re-starting your chain saw until you hear the motor come to a complete stop.

• If your chain does not come to rest within a few fractions of a second it is an indication that it needs tensioning (see Fig. C "Assembly of guide bar and chain").

Using Your Chain Saw (Fig. F)

AT TACHING EXTENSION CORD TO CHAIN SA W

An extension cord retainer is built into the switch handle that prevents the extension cord from pulling out of the handle. To use this feature, simply double the extension cord as shown in Figure F1, about a foot from the end, and insert it into the end of the handle. Hook the loop formed by doubling the cord over the tab, as shown in Figure F2. Gently tug on the cord to ensure that it is firmly retained in the saws handle. Plug the receptacle end of the extension cord into the tool's power supply cord. Figure F3 illustrates an alternate method for securing the extension cord to the saw power supply cord

NOTE: Always keep the cord away from the cutting area and and position the cord so that it will not be caught on branches, and the like, during cutting.
