Frequently Asked Questions - TCS33EDTP HiKOKI

How to start the engine when cold?

Set the switch to ON, prime the fuel bulb 10 times, close the choke, pull the starter until first ignition, then open the choke and pull again. Release the throttle after starting and disengage the chain brake.

How to adjust chain tension?

Loosen the bar nuts, turn the tensioning screw clockwise to tighten. The chain should have 0.5 to 1.0 mm play in the middle of the bar. Tighten the nuts.

What is the correct fuel/oil mixture?

Use unleaded 89 octane gasoline and high-quality 2-stroke oil (JASO FC or ISO EGC). The ratio is 25:1 to 50:1. For California, 50:1. Do not exceed 10% ethanol.

How to clean the air filter?

Remove the cover, take out the filter and the pre-filter sponge. Wash them in warm soapy water, dry thoroughly before reassembling. Replace the filter if worn.

What to do in case of kickback?

Hold the chainsaw firmly with both hands, never cut with the nose of the bar. In case of kickback, the chain brake activates automatically. Release the throttle and re-engage the brake if necessary.

How to sharpen the chain?

Wear gloves. File each cutter from the inside out with a round file. Respect the angles: 30° for the top face, 80° for the side face. Check the depth gauge height every three sharpenings.

How to store the chainsaw?

Empty the fuel tank, run the engine until it stops. Clean the machine, lightly oil the cylinder through the spark plug hole. Store in a dry place out of reach of children, with the guide bar cover in place.

Which chain oil to use?

Use good quality chain oil specifically for chainsaws. Never use used or recycled oil. Fill the oil tank every time you refuel.

How to check the chain brake?

Stop the engine. Hold the chainsaw horizontally, push the front hand guard toward the bar. The brake should lock the chain. To disengage, pull the guard forward. Test before each use.

Where to find spare parts?

Contact an authorized Tanaka dealer. Use the part numbers from the spare parts list in the manual. Use only original Tanaka parts.

SAFETY PRECAUTIONS FOR CHAIN SAW USERS

Kickback safety precautions

WARNING! : Kickback may occur when the nose or tip of the guide bar (kickback zone (1)) 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 toward the operator. Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back toward 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 upon the safety devices built into your saw. As a chain saw user, you should take several steps to keep your cutting jobs free from accident or injury. (Fig.1)

Fig. 1

With a basic understanding of kickback, you can reduce or eliminate the element of surprise. Sudden surprise contributes to accidents.
- Keep a good firm 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.
Make sure that the area in which you are cutting is free from obstructions. Do not let the nose of the guide bar contact a log, branch, or any other obstruction that could be hit while you are operating the saw.
Cut at high engine speeds.
Do not overreach or cut above shoulder height.
Follow the manufacturer's sharpening and maintenance instructions for the saw chain.
- Only use replacement bars and chains specified by the manufacturer or the equivalent.

Other safety precautions

Do not operate a chain saw with one hand! Serious injury to the operator, helpers, bystanders, or any combination of these persons may result from one-handed operation. A chain saw is intended for two-handed use.
Do not operate a chain saw when you are fatigued.
- Use safety footwear, snug-fitting clothing, protective gloves, and eye, hearing, and head protection devices.
Use caution when handling fuel. Move the chain saw at least 10 feet (3 m) from the fueling point before starting the engine.
Do not allow other persons to be near the chain saw when starting or cutting with the chain saw. Keep bystanders and animals out of the work area.
Do not start cutting until you have a clear work area, secure footing, and a planned retreat path from the falling tree.
- Keep all parts of your body away from the saw chain when the engine is running.
Before you start the engine, make sure that the saw chain is not contacting anything.
- Carry the chain saw with the engine stopped, the guide bar and saw chain to the rear, and the muffler away from your body.
Do not operate a chain saw that is damaged, improperly adjusted, or not completely and securely assembled. Be sure that the saw chain stops moving when the throttle control trigger is released.
Shut off the engine before setting the chain saw down.
- 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.
- When cutting a limb that is under tension, be alert for springback so that you will not be struck when the tension in the wood fibers is released.
- Keep the handles dry, clean, and free of oil or fuel mixture.
Operate the chain saw only in well-ventilated areas.
Do not operate a chain saw in a tree unless you have been specifi cally trained to do so.
All chain saw service, other than the items listed in the instruction manual(s) maintenance instructions, should be performed by competent chain saw service personnel. (For example, if improper tools are used to remove the fl ywheel or if an improper tool is used to hold the fl ywheel in order to remove the clutch, structural damage to the fl ywheel could occur and subsequently could cause the fl ywheel to burst.)

• When transporting your chain saw, use the appropriate guide-bar scabbard.
• When a chain saw is being used, a fire extinguisher should be available.

Chain brake operation (Fig. 10)

Fig. 10

Chain brake (15), is designed to activate in an emergency such as kick-back action. Please check to verify that it works properly before use.

Application of brake is made by moving the front hand guard towards the bar. During the chain brake operation, even if the throttle trigger is pulled, the engine speed does not increase and the chain does not turn. To release the brake, pull up the front hand guard.

If the engine keeps rotating at high speed with the brake engaged, the clutch will overheat causing trouble.

When the brake engages during operation, immediately release the throttle trigger to slow down the engine.

How to confirrm:

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.

Fig. 11

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

Starting the cold engine (Fig. 12-17) CAUTION

Follow the instructions in this manual for starting the engine.
Before starting, make sure that the bar/chain does not touch anything.

1. Make sure chain brake is engaged. (Fig. 12)

Fig. 12

1. Set ignition switch (16) to ON position. (Fig. 13)

Fig. 13

1. Push priming pump (17) about ten times so that fuel flows through priming pump into carburetor.(Fig. 14)

Fig. 14

1. Turn the choke lever (18) to choked position (Fig. 14). This will automatically lock the throttle in starting position.
2. Pull recoil starter briskly, taking care to keep the handle in your grasp and not allowing it to snap back. (Fig. 15)

Fig. 15

1. When you hear first ignition, return the choke lever to run position. (Fig. 14)
2. Pull recoil starter briskly again in the aforementioned manner. (Fig. 15)

NOTE

If engine does not start, repeat procedures from 4 to 7.

1. As soon as engine start, pull throttle trigger full once and release immediately. (Fig. 16)

Then half-throttle is disengaged.

1. Make sure chain brake is disengaged. (Fig. 17) Allow the engine about 2-3 minutes to warm up before subjecting it to any load.

Do not run the engine at high speed without the load to shorten the longevity of the engine.

Fig. 16
Fig. 17

Starting the warm engine

Use only 1, 2, 7, and 9 of the starting procedure for a cold engine.

If the engine does not start, use the same starting procedure as for a cold engine.

Chain lubrication test

Check that chain oil is discharged properly. When the saw chain starts to revolve, point the head of the guide bar to a stump, etc., and pull the throttle trigger to perform high-speed operation for around 10 seconds. If chain oil is sprayed over the stump, it is discharged properly. (Fig. 18)

Fig. 18

WARNING

Do not carry the machine with the engine running.

Stopping (Fig. 19)

Fig. 19

Decrease engine speed, and push ignition switch (16) to stop position.

WARNING

Do not put the machine where there are flammable materials such as dried grass, since the muffler is still hot after the engine has stopped.

NOTE

If the engine does not stop, it can be forced to stop by rotating the choke lever to the choked position. Before restarting the engine, ask our dealer for repairs.

WARNING

Do not overreach or cut above shoulder height.
Use extra caution when felling, and do not use the saw in a nose-high position or above shoulder height.

CHAIN CATCHER

The chain catcher is located on the power head just below the chain to further prevent the possibility of a broken chain striking the chain saw user.

WARNING

Do not stand in-line with chain when cutting.

BASIC TECHNIQUES FOR MAKING FELLING, LIMBING AND BUCKING CUTS

The intention of the following information is to provide you with the general introduction to wood cutting techniques.

WARNING

This information does not cover all specific situations, which may depend on differences in terrain, vegetation, kind of wood, form and size of trees, etc. Consult your servicing dealer, forestry agent or local forestry schools for advice on specific woodcutting problems in your area. This will make your work more effi cient and safer.
Avoid cutting in adverse weather conditions, such as dense fog, heavy rain, bitter cold, high winds, etc.

Adverse weather is often tiring to work in and creates potentially dangerous conditions such as slippery ground.

High winds may force the tree to fall in an unexpected direction causing property damage or personal injury.

CAUTION

Never use a chain saw to pry or for any purpose for which it is not intended.

WARNING

• Avoid stumbling on obstacles such as stumps, roots, rocks, branches and fallen trees. Watch out for holes and ditches. Be extremely cautious when working on slopes or uneven ground.

Shut off the saw when moving from one work place FELLING to another. Felling is more

Always cut at wide open throttle. A slow moving chain can easily catch and force the saw to jerk.

Never use the saw with only one hand.

You cannot control the saw properly and you may lose control and injure yourself severely.

Keep the saw body close to your body to improve control and reduce strain.

When cutting with the bottom part of the chain the reactive force will pull the saw away from you towards the wood you are cutting.

The saw will control the feeding speed and sawdust will be directed towards you. (Fig. 20)

Fig. 20

When cutting with the upper part of the chain the reactive force will push the saw towards you and away from the wood you are cutting. (Fig. 21)

Fig. 21

There is a risk of kickback if the saw is pushed far enough so that you begin to cut with the nose of the bar.

The safest cutting method is to cut with the bottom part of the chain. Sawing with the upper part makes it much more difficult to control the saw and increases the risk of kickback.

In case the chain locked, immediately release the throttle trigger.

If the throttle trigger keeps rotating at high speed with the chain locked, the clutch will overheat causing trouble.

NOTE

Always keep the spiked bumper face to a tree, because the chain may suddenly be drawn into a tree.

FELLING

Felling is more than cutting down a tree. You must also bring it down as near to an intended place as possible without damaging the tree or anything else.

Before felling a tree, carefully consider all conditions which may effect the intended direction, such as:

Angle of the tree. Shape of the crown. Snow load on the crown.

Wind conditions. Obstacles within tree range (e.g., other trees, power lines, roads, buildings, etc.).

WARNING

Always observe the general conditions of the tree. Look for decay and rot in the trunk which will make it more likely to snap and start to fall before you expect it.
- Look for dry branches, which may break and hit you when you are working.

Always keep animals and people at least twice the tree length away while felling. Clear away shrubs and branches from around the tree.

Prepare a path of retreat away from the felling direction.

BASIC RULES FOR FELLING TREES

Normally the felling consists of two main cutting operations, notching and making the felling cut. Start making the upper notch cut on the side of the tree facing the feeling direction. Look through the kerf as you saw the lower cut so you do not saw too deep into the trunk. The notch should be deep enough to create a hinge of suffcient width and strength. The notch opening should be wide enough to direct the fall of the tree as long as possible. Saw the felling cut from the other side of the tree between one and two inches (3-5 cm) above the edge of the notch. (Fig. 22)

Fig. 22

1. Felling direction
2. 45^ minimum notch opening
3. Hinge
4. Felling cut

Never saw completely through the trunk. Always leave a hinge.

The hinge guides the tree. If the trunk is completely cut through, you lose control over the felling direction. Insert a wedge or a felling lever in the cut well before the tree becomes unstable and starts to move. This will prevent the guide bar from binding in the felling cut if you have misjudged the falling direction. Make sure no people have come into the range of the falling tree before you push it over.

FELLING CUT, TRUNK DIAMETER MORE THAN TWICE GUIDE BAR LENGTH

Cut a large, wide notch. Then cut a recess into the center of the notch. Always leave a hinge on both sides of the center cut. (Fig. 23)

Fig. 23

Complete the felling cut by sawing around the trunk as in the Fig. 24.

Fig. 24

WARNING

These methods are extremely dangerous because they involve the use of the nose of guide bar and can result in kickback.

Only properly trained professionals should attempt these techniques.

LIMBING

Limbing is removing the branches from a feller tree.

WARNING

A majority of kickback accidents occur during. limbing.

Do not use the nose of the guide bar. Be extremely cautious and avoid contacting the log, other limbs or objects with the nose of the guide bar. Be extremely cautious of limbs under tension. They can spring back towards you and cause loss of control resulting in injury. (Fig. 25)

Fig. 25

Stand on the left side of the trunk. Maintain a secure footing and rest the saw on the trunk. Hold the saw close to you so that you are in full control of it. Keep well away from the chain. Move only when the trunk is between you and the chain. Watch out for spring back of limbs under tension.

LIMBING THICK BRANCHES

When limbing thick branches, the guide bar may get pinched easily. Branches under tension often snap up, so cut troublesome branches in small steps. Apply the same principles as for cross cutting. Think ahead and be aware of the possible consequences of all your actions.

CROSS CUTTING/BUCKING

Before starting to cut through the log, try to imagine what is going to happen. Look out for stresses in the log and cut through it in such a manner that the guide bar will not get pinched.

CROSS CUTTING LOGS, PRESSURE ON TOP

Take a firm stance. Begin with an upper cut. Do not cut too deeply, about 1/3 of the log diameter is enough. Finish with a bottom cut.

The saw cuts should meet. (Fig. 26)

THICK LOG, LARGER THAN GUIDE BAR LENGTH

Begin by cutting on the opposite side of the log. Pull the saw towards you, followed by previous procedure. (Fig. 27)

Fig. 27

If the log is lying on the ground make a boring cut to avoid cutting into the ground. Finish with a bottom cut. (Fig. 28)

Fig. 28

WARNING

KICKBACK DANGER

Do not attempt a boring cut if you are not properly trained. A boring cut involves the use of the nose of the guide bar and can result in kickback.

CROSS CUTTING LOGS, PRESSURE ON BOTTOM

Take a firm stance. Begin with a bottom cut. The depth of the cut should be about 1/3 of the log diameter. Finish with an upper cut. The saw cuts should meet. (Fig. 29)

THICK LOG, LARGER THAN GUIDE BAR LENGTH

Begin by cutting on the opposite side of the log. Pull the saw towards you, followed by previous procedure. Make a boring cut if the log is close to the ground. Finish with a top cut. (Fig. 30)

Fig. 30

WARNING KICKBACK

DANGER

Do not attempt a boring cut if you are not properly trained. A boring cut involves the use of the nose of the guide bar and can result in kickback. (Fig. 31)

Fig. 31

IF THE SAW GETS STUCK

Stop the engine. Raise the log or change its position, using a thick branch or pole as a lever. Do not try to pull the saw free. If you do, you can deform the handle or be injured by the saw chain if the saw is suddenly released.

MAINTENANCE

MAINTENANCE, REPLACEMENT OR REPAIR OF THE EMISSION CONTROL DEVICES AND SYSTEM MAY BE PERFORMED BY ANY NON-ROAD ENGINE REPAIR ESTABLISHMENT OR INDIVIDUAL.

Carburetor adjustment (Fig. 32)

Fig. 32

WARNING

Never start the engine without the complete side case.

Otherwise the clutch can come loose and cause personal injuries.

In the carburetor, fuel is mixed with air. When the engine is test run at the factory, the carburetor is adjusted. A further adjustment may be required, according to climate and altitude. The carburetor has one adjustment possibility:

T = Idle speed adjustment screw.

Idle speed adjustment (T)

Check that the air filter is clean. When the idle speed is correct, the cutting attachment will not rotate. If adjustment is required, close (clockwise) the T-screw, with the engine running, until the cutting attachment starts to rotate. Open (counter-clockwise) the screw until the cutting attachment stops. You have reached the correct idle speed when the engine runs smoothly in all positions well below the rpm when the cutting attachment starts to rotate.

If the cutting attachment still rotates after idle speed adjustment, contact Tanaka dealer.

WARNING

When the engine is idling the cutting attachment must under no circumstances rotate.

NOTE

Some models sold in areas with strict exhaust emission regulation do not have high and low speed carburetor adjustments. Such adjustments may allow the engine to be operated outside of their emission compliance limits. For these models, the only carburetor adjustment is idle speed.

If you are not familiar with this type of adjustment, please ask for assistance from Tanaka dealer.

Air fi Iter (Fig. 33)

The air filter (37) and cleaner sponge (36), (38) must be cleaned from dust and dirt in order to avoid:

Carburetor malfunctions.
Starting problems.
Engine power reduction.
Unnecessary wear on the engine parts.
Abnormal fuel consumption.

Clean the air filter daily or more often if working in exceptionally dusty areas.

Cleaning the air fi iter

Remove the air filter cover (35) and the cleaner sponge (36). Turn the air filter (37) 20^ counterclockwise and remove. Then remove the cleaner sponge (38).

Rinse them in warm soap suds. Check that the filter is dry before reassembly. An air filter that has been used for some time cannot be cleaned completely. Therefore, it must regularly be replaced with a new one. A damaged filter must always be replaced.

Fig. 33

Spark plug (Fig. 34)

The spark plug condition is influenced by:

An incorrect carburetor setting.
Wrong fuel mixture (too much oil in the gasoline)
A dirty air filter.
- Hard running conditions (such as cold weather). These factors cause deposits on the spark plug electrodes, which may result in malfunction and starting difficulties. If the engine is low on power, difficult to start or runs poorly at idling speed, always check the spark plug first. If the spark plug is dirty, clean it and check the electrode gap. Readjust if necessary. The correct gap is 0.024'' (0.6 mm). The spark plug should be replaced after about 100 operation hours or earlier if the electrodes are badly eroded.

Fig. 34

Fig. 37

NOTE

In some areas, local law requires using a resistor spark plug to suppress ignition signals. If this machine was originally equipped with resistor spark plug, use same type of spark plug for replacement.

Oiler port (Fig. 35)

Clean the chain oiler port (39) whenever possible.

Fig. 35

Guide bar (Fig. 36)

Before using the machine, clean the groove and oiler port (40) in the bar with the special gauge off ered as an optional accessory.

Fig. 36

Side case (Fig. 37)

Always keep the side case and drive area clean of saw NO dust and debris. Periodically apply oil or grease to this area to protect from corrosion as some trees contain high levels of acid.

Fuel fi Iter (Fig. 38)

Remove the fuel filter from the fuel tank and thoroughly wash it in solvent. After that, push the filter into the tank completely.

Fig. 38

NOTE

If the filter is hard due to dust and dirt, replace it.

Chain oil filter (Fig. 39)

Remove the oil filter and thoroughly wash it in solvent. After that, push the filter into the tank completely.

Fig. 39

NOTE

If the filter is hard due to dust and dirt, replace it.

Cleaning the cylinder fins (Fig. 40) When wood chips are caught between cylinder fins (41), the engine may overheat, resulting in lower output. To avoid this, always keep cylinder fins and fan case clean.

Fig. 40

For long-term storage Drain all fuel from the fuel tank. Start and let engine run until it stops. Repair any damage which has resulted from use. Clean the unit with a clean rag, or the use of high pressure air hose. Put a few drops of two-cycle engine oil into the cylinder through the spark plug hole, and spin the engine over several times to distribute oil. Cover the unit and store it in a dry area.
