1. For Safe Operation

1. Never operate a chain saw when you are fatigued, ill, or upset, or under the influence of medication that may make you drowsy, or if you are under the influence of alcohol or drugs.

2. Use safety footwear, snug fitting clothing and eye, hearing and head protection devices.

3. Always use caution when handling fuel.

Wipe up all spills and then move the chain saw at least ten(10) feet(three(3) m) from the fueling point before starting the engine.

3a) Eliminate all sources of sparks or flame (ie. smoking, open flames, or work that can cause sparks) in the areas where fuel is mixed, poured, or stored.

3b) Do not smoke while handling fuel or while operating the chain saw.

4. Do not allow other persons to be near the chain saw when starting the engine or cutting a wood. Keep bystanders and animals out of the work area. Children, pets, and bystanders should be a minimum of thirty(30) feet away when you start or operate the chain saw.

5. Never start cutting until you have a clear work area, secure footing, and planned retreat path from the falling tree.

6. Always hold the chain saw firmly with both hands when the engine is running.

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

7. Keep all parts of your body away from the saw chain when the engine is running.

8. Before you start the engine, make sure the saw chain is not contacting anything.

9. Always carry the chain saw with the engine stopped, the guide bar and saw chain to the rear, and the muffler away from your body.

10. Always inspect the chain saw before each use for worn, Ioose, or changed parts. Never operate a chain saw that is damaged, improperly adjusted, or is not completely and securely assembled. Be sure that the saw chain stops moving when the throttle control trigger is released.

11. All chain saw service, other than the items listed in the Operator’s Manual, should be performed by competent chain saw service personnel. (e.g., if improper tools are used to remove the flywheel, or if an improper tool is used to hold the flywheel in order to remove the clutch, structural damage to the flywheel could occur which could subsequently cause the flywheel to disintegrate).

12. Always shut off the engine before setting it down.

13. Use extreme caution when cutting small size brush and saplings because slender material may catch the saw chain and be whipped toward you or pull you off balance.

14. When cutting a limb that is under tension, be alert for spring back so that you will not be struck when the tension in the wood fibers is released.

15. Keep the handles dry, clean and free of oil or fuel mixture.

16. Operate the chain saw only in well ventilated areas. Never start or run the engine inside a closed room or building.

Exhaust fumes contain dangerous carbon monoxide.

17. Do not operate a chain saw in a tree unless specially trained to do so.

18. Guard against kickback. Kickback is the upward motion of the guide bar which occurs when the saw chain at the nose of the guide bar contacts an object.

Kickback can lead to dangerous loss of control of the chain saw.

19. When transporting your chain saw, make sure the appropriate guide bar scabbard is in place.

20. This chain saw is equipped with a spark arrester built-in muffler. Periodically check the arrester to keep it in good order.

KICKBACK SAFETY PRECAUTIONS FOR

CHAIN SAW USERS

– 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 personal injury.

● Do not rely exclusively on the safety devices built into your saw. As a chain saw user you should take several steps to keep cutting jobs free from accident or injury.

(1) With a basic understanding of kickback you can reduce or eliminate the element of surprise. Sudden surprise contributes to accidents.

(2) Keep a good grip on the saw with both hands, the right hand on the rear handle, and the left hand on the front handle, when the engine is running. Use a firm grip with thumbs and fingers encircling the chain saw handles. A firm grip will help you reduce kickback and maintain control of the saw. Don’t let go.

(3) Make certain that the area in which you’re cutting is free from obstructions. Do not let the nose of the guide bar contact a log, branch, or any other obstruction which could be hit while you are operating the saw.

(4) Cut at high engine speeds.

(5) Do not overreach or cut above shoulder height.

(6) Follow manufacturers sharpening and maintenance instructions for saw chain.

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

2. Installing Guide Bar and Saw Chain

The saw chain has very sharp edges. Use thick protective gloves for safety.

1. Loosen the nuts and remove the chain cover.

2. Install the attached spike to the power unit.

3. Gear the chain to the sprocket and, while fitting the saw chain around the guide bar, mount the guide bar to the power unit, Then adjust the position of chain tensioner nut on the chain cover to the lower hole of guide bar.

Note:

Pay attention to the correct direction of the saw chain.

4. Fit the chain cover to the power unit and fasten the nuts to finger tightness.

5. While holding up the tip of the bar, adjust the chain tension by turning the tensioner screw until the tie straps just touch the bottom side of the bar rail.

6. Tighten the nuts securely with the bar tip held up. Then check the chain for smooth rotation and proper tension while moving it by hand. If necessary, readjust with the chain cover loose.

7. Tighten the tensioner screw.

Note :

A new chain will expand its length in the beginning of use. Check and readjust the tension frequently as a loose chain can easily derail or cause rapid wear of itself and the guide bar.

3. Fuel and Chain oil

■ FUEL

The RedMax engines are lubricated by oil specially formulated for air-cooled 2-cycle gasoline engine use. If RedMax oil is not available, use an anti-oxidant added quality oil expressly labeled for air-cooled 2-cycle engine use.

RECOMMENDED MIXING RATIO

GASOLINE 32 : OIL 1

Exhaust emission are controlled by the fundamental engine parameters and components (eq., carburation, ignition timing and port timing) without addition of any major hardware or the introduction of an inert material during combustion.

These engines are certified to operate on un-leaded gasoline.

WARNING !

The fuel is highly flammable. Do not smoke or bring any flame or sparks near fuel.

• HOW TO MIX FUEL

1. Measure out the quantities of gasoline and oil to be mixed.

2. Put some of the gasoline into a clean, approved fuel container.

3. Pour in all of the oil and agitate well.

4. Pour in the rest of gasoline and agitate again for at least one minute.

5. Put a clear indication on the outside of the container to avoid mixing up with gasoline or other containers.

FOR YOUR ENGINE LIFE, AVOID;

1. FUEL WITH NO OIL(RAW GASOLINE) –

It will cause severe damage to the engine inner parts very quickly.

2. GASOHOL – It can cause deterioration of rubber and/or plastic parts and disruption of engine lubrication.

3. OIL FOR 4-CYCLE ENGINE USE or

WATER COOLED 2-CYCLE ENGINE

USE – It can cause spark plug fouling, exhaust port blocking, or piston ring sticking.

■ CHAIN OIL

Use motor oil SAE 10W-30 all year round, or

SAE 30-40 in summer and SAE 20 in winter.

NOTE:

Do not use waste or regenerated oil that can cause damage to the oil pump.

4. Operating Engine

Starting engine

1. Fill fuel and chain oil tanks respectively, and tighten the caps securely.

2. Tilt the switch lever upward.

3. While holding the throttle lever together with the throttle interlock, push in the side latch and release the throttle lever to hold it at the starting position.

4. Pull out the choke knob to the closed position.

Note:

When restarting immediately after stopping the engine, Ieave the choke knob at the open position.

6

5. While holding the saw unit securely on the ground, pull the starter rope vigorously.

Do not start the engine while hanging the chain saw with a hand. The saw chain may touch your body. It's very dangerous.

6. When engine has ignited first, push in the choke knob and pull the starter again to start the engine.

7. Allow the engine to warm up with the throttle lever pulled slightly.

Keep clear of the saw chain as it will start rotating upon starting of engine.

Checking oil supply

After starting the engine, run the chain at medium speed and see if chain oil is scattered oft as shown in the figure.

The chain oil flow can be changed by inserting a screwdriver in the hole on bottom of the clutch side. Adjust according to your work conditions.

Note:

The oil tank should become nearly empty by the time fuel is used up. Be sure to refill the oil tank every time when refueling the saw.

Adjusting carburetor

The carburetor has been adjusted at the factory.

Should your unit need readjustment due to the changes in altitude or operating conditions, please let your skillful dealer make the adjustment. A wrong adjustment may cause damage to your unit.

If you have to make the adjustment yourself, please carefully follow the procedure below.

Note :

Be sure to adjust the carburetor with the bar chain attach ed.

7

1. H and L needles are restricted within the number of turn as shown below, because this engine conforms to 1995 California regulations for utility and lawn and garden equipment engines as applicable.

H needle:

L needle:

1 /

4 fixed

2. Start engine and allow it to warm up in low speed for a few minutes.

3. Turn idle adjusting screw (T) counterclockwise so that saw chain does not turn. If idling speed is too slow, turn the screw clockwise.

4. Make a test cut adjust the H needle for best cutting power, not for maximum speed.

Icing prevention system

This system prevents icing of the carburetor which sometimes happen while sawing in winter.

When your saw is possible to be frozen at the carburetor during operation, use the system as follows:

1. Loosen a screw and remove the screen on the back of the air cleaner cover.

2. Turn the screen a half and reinstall to the cover.

Never use the system in normal temperature because that can cause starting failure due to overheating of the carburetor.

When using the saw with the anti-icing setting, frequently check the screen and keep it clean of saw dust.

8

Chain brake

This machine is equipped with an automatic brake to stop saw chain rotation upon occurrence of kickback while in saw cutting operation. The brake is automatically operated by inertial force which acts on the weight fitted inside the front gurd.

This brake can also be operated manually with the front guard turned down to the guide bar.

To release brake, pull up the front guard toward the front handle till “click” sound is heard.

[Caution]

Be sure to confirm brake operation on the daily inspection.

How to confirm:

1) Turn off the engine.

2) Holding the chain saw horizontally, release your hand from the front handle, hit the tip of the guide bar to a stump or a piece of wood, and confirm brake operation. Operating level varies by bar size.

In case the brake is not effective, ask our dealer inspection and repairing.

The engine, if being kept rotated at high speed with the brake engaged, heats the clutch, causing a trouble. When the brake is operated while in operation, immediately release your fingers from the throttle lever and stop the engine.

Stopping engine

1. Release the throttle lever to allow the engine idling for a few minutes.

2. Move the switch lever downward.

9

5. Sawing

NOTE:

• Before proceeding to your job, read “For

Safe Operation” section. It is recommended to first practice sawing easy logs. This also helps you get accustomed to your unit.

• It is not necessary to force the saw into the cut. Apply only light pressure while running the engine at full throttle.

• Racing the engine with the chain seized in a cutaway can damage the clutch system.

When the saw chain is caught in the cut, do not attempt to pull it out by force, but use a wedge or a lever to open the cut.

■ GUARD AGAINST KICKBACK

• This saw is equipped with a special “low kickback” chain that greatly reduces the severty of kickback should it occur.

• The saw chain has been tested in accordance with American National

Standard Safety Specifications for gasoline powered chain saw (ANSI

B175.1 1985) as having an acceptable low kickback level. On this saw never use any chain other than those recommended on page 12 of this manual, or which is not designated as meeting the ANSI B175.1

kickback levels on this saw.

• Low kickback saw chains are chains which have met the kickback requirements of ANSI B175.1 when tested on the representative samples of chain saws below 3.8 C.I.D. specified in ANSI

B175.1.

• The guide bar supplied with this saw has an under 1.2 inch radius sprocket nose which produces a specific kickback energy. Never use a bar with a larger nose radius. Use only those recommended on page 12.

• The length of bars has a great effect on kickback. Use only those length as specified on page 12.

• This saw is also equipped with a chain brake that will stop the chain in the event of kickback if operating properly. You must check the chain brake operation before each usage by running the saw at full throttle for 1 or 2 seconds and pushing the front hand guard forward. The chain should stop immediately with the engine at full speed. If the chain is slow to stop or does not stop then replace the brake band and clutch drum before use.

• It is extremely important that the chain brake be checked for proper operation before each use and that the chain be sharp in order to maintain the kickback safety level of this saw. Removal of the safety devices, inadequate maintenance, or incorrect replacement of the bar or chain may increase the risk of serious personal injury due to kickback.

■ FELLING A TREE

[CAUTION!] When you fell a tree, be sure to warn your neighboring workers of the danger.

10

1. Decide the felling direction considering the wind, Iean of the tree, location of heavy branches, ease of job after felling, and other factors .

2. While clearing the area around the tree, arrange a good foothold and retreat path.

3. Make a notch cut one-third of the way into the tree on the felling side.

4. Make a felling cut from the opposite side of the notch and at a level slightly higher than the bottom of the notch.

■ LOGGING AND LIMBING

[CAUTION!]

1. Always ensure your foothold as well as stability of the tree.

2. Be alert to the rolling over of a cut log.

3. Read the instructions in “For Safe

Operation” to avoid kickback of the saw.

Before starting work, check the direction of bending force inside the log to be cut.

Always finish cutting from the opposite side of bending direction to prevent the guide bar from being caught in the cutaway.

• Cutting an unpillowed log

Saw down halfway, then roll the log over and cut from the opposite side.

• Limbing a felled tree

[CAUTION!]

Be alert to the spring back of a cut limb.

First check which way the limb is bent. Then make a shallow cut into the compressed side to prevent the limb from being torn. Cut through from the tensed side.

• Pruning

[CAUTION!]

1. Do not use an unstable foothold or a stepladder.

2. Do not overreach.

3. Do not cut above shoulder height.

4. Always use both hands to grip the saw.

Cut up from the bottom, finish down from the top.

• Cutting a pillowed log

In the area A in the picture right above, saw up from the bottom one-third and finish by sawing down from the top. In the area B, saw down from the top one-third and finish by sawing up from the bottom.

6. Maintenace

Before cleaning, inspecting or repairing your unit, make sure that engine has stopped and is cool. Disconnect the spark plug to prevent accidental starting.

A. Maintenance after each use

1. Air filter

Dust on the cleaner surface can be removed by tapping a corner of the cleaner against a hard surface. To clean dirt in the meshes, split the cleaner into halves and brush in gasoline. When using compressed air, blow from the inside.

To assemble the cleaner halves, press the rim until it clicks.

2. Oiling port

Dismount the guide bar and check the oiling port for clogging.

3. Guide bar

When the guide bar is dismounted, remove sawdust in the bar groove and the oiling port.

Grease the nose sprocket from the feeding port on the tip of the bar.

4. Others

Check for fuel leakage and loose fastenings and damage to major parts, especially handle joints and guide bar mounting. If any defects are found, make sure to have them repaired before operating again.

12

B. Periodical service points

1. Cylinder fins

Dust clogging between the cylinder fins will cause overheating of the engine. Periodically check and clean the cylinder fins after removing the air cleaner and the cylinder cover. When installing the cylinder cover, make sure that switch wires and grommets are positioned correctly in place.

2. Fuel filter

(1) Using a wire hook, take out the filter from the filler port.

(2) Disassemble the filter and wash with gasoline, or replace with a new one if needed.

Note:

• After removing the filter, use a pinch to hold the end of the suction pipe.

• When assembling the filter, take care not to allow filter fibers or dust inside the suction pipe.

3. Oil tank

With a wire hook, take out the oil filter through the filler port and clean in gasoline. When putting the filter back into the tank, make sure that it comes to the front right corner. Also clean off dirt in the tank.

4. Spark plug

Clean the electrodes with a wire brush and reset the gap to .025 in. as necessary.

Note:

Use a Champion RCJ-7Y or NGK BPMR7A for replacement.

5. Sprocket

Check for cracks and for excessive wear interfering with the chain drive. If the wearing is found obviously, replace it with a new one. Never fit a new chain on a worn sprocket, or a worn chain on a new sprocket.

6. Front and Rear dampers

Replace if adhered part is peeled or crack is observed on the rubber part.

13

7. Maintenace of Saw Chain and Guide Bar

A. Saw Chain

It is very important for smooth and safe operation to keep the cutters always sharp.

Your cutters need to be sharpened when:

• Sawdust becomes powder-like.

• You need extra force to saw in.

• The cut way does not go straight.

• Vibration increases.

• Fuel consumption increases.

Cutter setting standards:

Be sure to wear safety gloves.

Before filing:

• Make sure the saw chain is held securely.

• Make sure the engine is stopped.

• Use a round file of proper size for your chain.

Chain type 33SL

File size 4.5mm

Place your file on the cutter and push straight forward.

Keep the file position as illustrated.

14

After every cutter has been set, check the depth gauge and file it to the proper level as illustrated.

Be sure to round off the front edge to reduce the chance of kickback or tie-strap breakage.

Make sure every cutter has the same length and edge angles as shown below.

15

B. Guide Bar

• Reverse the bar occasionally to prevent partial wear.

• The bar rail should always be a square. Check for wear of the bar rail. Apply a ruler to the bar and the outside of a cutter. If a gap is observed between them, the rail is normal. Otherwise, the bar rail is worn. Such a bar needs to be corrected or replaced.
