WARNINGS AND SAFETY INSTRUCTIONS

(See Additional Safety Instructions throug^hout this Manual)

GUARD AGAINST KICKBAGK

^ckback is a dangerous reaction that can lead to serious in jury. Do not rely only on the safety devices provided with your saw. As a chain saw user, you must take special safety

recautions to help keep your cutting jobs free from acci-

ent or iniuiy.

!^cKback occur when the moving chain con tacts ^ olnect at the upper portion of the tip of the goide bar or when the wood closes in and pincnes the saw chain in the cut. Contact at the upper portion of the tip of the guide bar can cause the chain to dig into the object, which stops the chain for an instant. The result is a lightning fast j reverse reaction which kicks the

lide bar up and back toward the operator. If the

saw chain is pinched along the top of the guide

bar, the guide bar can be rapidly dnven back to ward the operator. Either of these reactions cap cause loss of saw control which can result in seri ous injury

_______

A KICKBACK WARNING

....

___________________

REDUCE THE CHANCE OF KICKBACK

Recognize that kickback can happen. With a basic understanding of kickback, you can reduce the element of surprise which contributes to accidents.

Never let the moving chain contact any object at the tip of the guide ban Figure 1.

Keep the working area free from obstructions such as other trees, brandies, rocks, fences, stumps, etc. Figure 2, Eliminate or avoid any obstruction that your saw chain cotdd hit while you áre cutting

throu^ a particular log or branch,

^ep your saw chain sharp and properly ten sioned. A loose or dull chain can increase the chance of kickback to occur. Follow manufacturer’s chain

shaipening and maintenance instructions. Check tension at regular intervals with the engine stopped, never with the engine running. Make sure the bar clamp nuts are securely ti^tened after tensioning the cnain.

Begin and continue cutting at full throttle. If

the chain is moving at a slower speed, there is greater chance for kickback to occur.

Cut one log at a time.

Use extreme caution when re-entering a pre

7. vious cut.

Do not attempt plunge cuts. Watch for shifting logs or other forces that could

9. close a cut and pinch or fall into chain.

lO^Use the Reduced-Kickback Guide Bar and Low-Kickback Chain specified for your saw;

MAEVTAIN CONTROL

Keep a good, firm grip on the saw with both

hands ^cmen the engine is running and don’t let go. Figure 3 . A &m grip can neutralize kick-

your are right handed or left handed. Keepyourleft arm straight with the elbow locked.

2. Position your left hand on the front handlebar so it is in a straight line with your right hand on the rear handle when making bucking cuts. Figure 3 . Never reverse right ana left hand posi tions for any t3pe of cutting.

3. Stand with your weight evenly balanced on

both feet.

4i. Stand slightly to the left ride of the saw to

keep your body from being in a direct line with the cutting chain. Figure 3 .

5. Do not overreach. You could be drawn or thrown off balance and lose control of the saw.

6., Do not cut above shoulder height. It is difficult to maintain control of the saw above shoulder height

^' places the moving chain dangerously close to

yoxu* upper body.

WARNINGS AND SAFETY INSITIUCTIONS (continued)

A WARNING

Because a chaiu saw is a higb-sj^d wood-cuttiug tool, special safety precau tions must be observed to reduce the risk of accidents. Careless or improper use of this tool can cause serious ipjuiy^

KNOWypUKSAW

1. Read your operator's manual carefully until you completely understand and can follow all safety rules, precautions, and operating instructions before attempting to operate the unit.

Restrict the use of your saw to adult users who

imderstand and can follow safety rules, precautions, and operating instructions fouhd in this manu;^.

4. Do not attempt to use your chain saw during bad weather conditions such as strong wind, rain, snow, ice, etc., or at night.

5. Carefully plan your sawing operation in ad vance. Do not start cutting tmtif you have a clear work area, secure footing, and, if you are fellingtrees, a planned retreat path.

AVOID REACTIVE FORCES

Pinch-Kickback and Pull-In occur when the chain is suddenly stopped by beingpinched, caught, or by contacting a foreign object m the wood. This sudden stopping of the chain results in a reversal of the (bain force usea to cut wood and causes the saw to move in the opposite direction of the chain rotation. Pinch-Kickbaek drives the saw straight hack toward the operator. Pull-In pulls the saw away from the operator. Either reaction can result in loss of control and possibly serious injury.

To avoid Pinch-Kickback;

1. Be extremely aware of situations or obstruc tions that can cause material to pinch the top of or otherwise stop the chain.

2. Do not cut more than one log at a time.

3. Do not twist the saw as the bar is withdrawn from an under-cut when bucking.

To avoid Pull-In;

1. Always begin cutting with the engine at full throttle and the saw housing against wood.

2. Use wedges made of plastic or wood, (never of metal) to hold the cut open.

PIANAHEIAD

1. Wear protective gear. Figure 4 v Always use

steel-toed safety footwear with non-slip soles; sni^fitting cIothing;beavy-duty, non-slip gloves; eye protiecripn such as imn-fogging, vented ga^es or fac^ screen; an approved safety hard hat; andsound ba^^ riers-^-^ear plugs or mufflers to protc^ your hearing. Regular users shpuld have bealuig cheijied regularfy

Do not operate saw from a ladder or in a tree.

Position all parts of your body to the left of cut

and away from the saw chain when the engine

is running.

Cut wood on^ Do not use your saw to piy or shove away limbs, roots, or other objects.

Make sure the chain will not make contact with any object while starting the engine.

Never tiy to start the saw when the guide bar is in a cut or kerf

7. Use extreme caution when cutting small size brush and saplings. Slender matenal can catch

the saw chain and be whipped toward you or pull you off balance.

8. Be alert for sprin^ack when cutting a limb that is under tension so you will not be struck by the limb or saw when the tension in the wood fibers is re leased.

9. Do not put pressure on the saw at the end of a cut. Applying pressure can Cause you to lose control

when the cut is completed.

10. Stop the engine before setting the saw down.

MAINTAIN YOUR SAW IN GOOD

WORKING ORDER

1. Have aU chain saw service performed by a qualiHed service dealer with the exception of me

items listed in the maintenance section of this manu al. For example, if improper tools are used to remove

or hold the flywheel when servicing the clutch, struc tural damage to the flywheel can occur and cause the flywheel to burst.

Keep ftiel apd oil caps, screws, and fasteners securely tightened.

Keep the handles dry, clean, and free of oil or

3. fuelmixture^

Make certain the saw chain stops moving when the throttle trigger is released. For cor

rection, refer to “Carburetor Adjustments.”

Stop the saw if the chain strikes a foreign ob

ject. Check for alignment, binding, breakage, and

mounting of moving parts and any other condition

that may affect the operation of the unit. Check guards and all other parts to see if each will operate properly and perform its intended function. Any part

that is damaged should be properly repaired or re placed by using the instructions in mis manual or by taking your unit to your Authorized Service Dealer.

6. Disconnect the spark plug before performing any maintenance except for carburetor ac(just-

ments.

KNOW YOUR UNIT

A. INTRODUCTION

Your saw has been designed with safety in mind and in

cludes the following safety features as standard equip

ment:

• Reduced-Kickback Guide Bar

• Low-Kickback Chain

• , Handguard

• Spark Arrestor

• Temperature Limiting Muffler

• Anti-vibration System

• Turbo Clean"* Air Filter System

A WARNING The following features aré included on your saw to he^ reduce the hazard of kickback; however, such léatures will not totally eliminate this dan gerous reaction. As a chain saw user, do not rely only on safety devices. You must follow all safety

precautions, instructions, and maintenance in this manual to help avoid kickback and other

forces which can result in serious iiijury.

B. KICKBACK SAFETY FEATURES

• RedUced-Eickback Guide Bar, designed with a

small radius tip which reduces the size of the kickback danrer zone on the bar tip. Figure 5. A Redu ced-Kickback Guide Bar is one which has been dem

onstrated to significantly reduce the number and se riousness of kickbacks when tested in accordance with the safety requirements for gasoline powered chain saws as set by the American National Stan dards Institute, Inc., Standard B175.1 -1991.

• Low-Kickback Chain, designed with a contoured

depth gauge and guard link which deflect kickback force and allow wood to gradually ride into the cut ter. Figure 5. Low-Kickback Chain is chain which has met kickback perform2mce requirements of

ANSI B175.1 (Safety Requirements for GasolinePowered Chain Saws) when tested on a rejiresentative sample of chain saws below 3.8 cubic inch dis placement specified in ANSI B175.1.

• Handguard, designed to reduce the chance of your left hand contacting the chain ifyourhand slips off the front handlebar.

• Position of front and rear handlebars, de

signed with distance between handles and “in-line”

with each other. The ^read and “in-line” position of the hands prorided by this design work together to give balance and resistance in controlling ot of the saw back toward the operator occurs.

A. GETTING READY

1. READ YOUR OPERATOR’S MANUAL CAREFULIY

Your Operator’s Manual has been developed to help you prepare your saw fpr use and to understand its safe operation. It is important that you read your manual completely to become familiar with the unit before you begin assembly or attempt opera tion. Your POULAN PRO dealer is available to show you how to operate your saw Be sure to ask for his assistance.

B. ATTACHING THE SPUR (Optional)

The spur is a special piece of equipment de signed to assist thei cutting operation. When as sembled to saw, the spur will dig into tree or log and:

• relieve contact pressure adding ease to the sawing operation.

• allow the saw to be more easily rotated or

pivoted into the cut.

To Install:

1. Remove the bar clamp nuts, bar clamp, and plastic

spacer. Figure 6. Discard plastic spacer.

NOTE; Be sure to remove the plastic spacer on the

bar stud (between bar clamp and crankcase).

2. Remove the isolator bracket screw. Figure?.

3. Remove and discard the spacer under the isolator bracket. Figure 7.

4. Position the spur over the two holes in the shroud. Figure 6, Make sure the bottom screw hole tab on

the spur is positioned betw^eh the shroud and the isolator bracket (where the spacer was removed).

5. Insert the two spur screws and tighten evenly and securely.

2. HAVE THE FOLLOWING AVAILABLE: a. Protective gloves.

b. Approved, marked fuel container. c. One gallon regular unleaded gasoline. d. 2 (ycle, air-cooled engine oil (See the “Fueling

e. ATTACHING THE BAR AND CHAIN

• Your saw is equ^ped with a Reduced-Kick back Bar and a Low-^ckback Chain.

• Always use the Reduced-Backback Guide Bar and Low-Kickback Chain specified for your chain saw model when replacing these parts. See the “Specifications^ section.

A WARNING

Do not start the engine without the guide bar and

chain completely assembled. Otherwise, the

clutch can come off and serious injury can result.

I CAUnON: I Wear protective gloves when han dling or operating your saw. The chain is sharp

and can cut you even when it is not moving!

1. Removetheharclampnuts, bar clamp, and ]}}astic spacer if you have not already done so. Discaard

plastic spacer.

2. Turn the adjusting screw (Fig^ lO) counter clockwise to move the adjusting pin almost as far as it will go to the rear.

3. Mount the guide bar imth the slotted end over the

moimting studs. Figi^ 8 . Position the adjusting pin in the adjusting pin hole. Figure 8.

4. Hold the chain with the cutters facing as shown in Figure 9 (inset).

5. Place the chain over and behind the clutch drum and onto the sprocket. Figure 9 . Fit the bottom of

the drive links between the teeth in the sprocket.

6. Slide the ^de bar towaid the rear of the saw as far as possible.

7. Start at the top of the bar and fit chain drive links into the groove around the guide bar. Figure 9.

8. Turn the adjusting pin clockwise until the chain is snug in the guide bar groove. Figure 10.

D. CHAIN TENSION

• Ck>rrect Chaiu Tensipu is very im^rtant—

- A loose chain will wear thè bar and itself

- A loose chain can jtunp off the bar while you are cutting

- A tight chain can break or damage the saw and/ orbar.

• The chain stretches during use, especi^y when new. Check tension periodically as follows:

- each time the saw is used;

- more frequently when the chain is nev^

- as the chain warms up to normal operating

temperature.

• Chain tension is correct when the chain: ~ can be lifted about 1/8" from the Guide Bar at a

point near the middle of the bar and will move freely around the bar.

installing a new chain, allowthe chain to be lifted 1/4" from the bar. Thereafter, follow the instructions as indicated.

• Chain tensioning procedure:

I WARNING: i Always wear ^oves when handl-

ihg the chain. The chain is shaxm and can cut

you even when it is not moving!

NOTE; The bar clamp nuts must be no more than

finger tight to tension the chain correctly.

NÓTE; Hold tip of guide bar up through step 4.

1. yft up the tip of the guide bar and turn the adjust ing screw clockwise until the chain does not sag be neath the guide bar. Figúrelo.

2. Check the tension by lifting the chain from the guide bar at the center of the bar. Figure 11.
