GENERAL SAFETY RULES

WARNING!

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

a)Keep work area clean and well lit.

Cluttered and 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 of 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.

APPLICATION

General wood cutting.

PRIOR TO OPERATION

1.Power source

Ensure that the power source to be utilized conforms to the power requirements specified on the product nameplate.

2.Power switch

Ensure that the power switch is in the OFF position. If the plug is connected to a receptacle while the power switch is in the ON position, the power tool will start operating immediately, which could cause a serious accident.

3.Extension cord

When the work area is removed from the power source, use an extension cord of sufficient thickness and rated capacity. The extension cord should be kept as short as practicable.

4.Confirm the chain tension

Improper chain tension may result in damage to the chain and the guide bar, and could cause serious accident. Always confirm that there is proper tension on the chain prior to operation.

5.Fill the oil tank with oil

This unit is shipped without oil in the oil tank. Prior to operation, remove the oil cap and fill the tank with accessory oil. (CS-350A)

This unit is shipped without oil in the oil tank. Prior to operation, remove the oil cap and fill the tank with chain saw oil (sold separately), or SAE 20 or 30 motor oil. (CS35B)

Do not use stained or degraded motor oil. Check oil reservoir periodically and keep it filled while running saw.

6.Oiling the guide bar and chain

By pushing the oil button, oil is supplied to the guide bar and chain. Before starting cutting work, turn on the saw and push the oil button 3 or 4 times to ensure that oil is well circulated. (CS-350A)

Automatic chain lubrication (CS35B)

7.It is recommended to use an earth-leakage circuit breaker or a residual current device.

ADJUSTING THE CHAIN TENSION

1.Loosen the bolt securing the chain cover with the accessory wrench, as shown in Fig. 1. It is not necessary to remove the bolt.

2.While lifting the tip of the guide bar, turn the adjusting screw with the accessory minus-head screwdriver to adjust the chain tension, as shown in Fig. 2. The chain tension is increased by turning

6

English

the adjusting screw clockwise, and slackened by turning it counterclockwise.

3.The chain tension must be adjusted so that a 0.5– 1.0 mm gap appears between the chain drive links and the guide bar when the chain is lightly raised at the center section of the guide bar as shown in

Fig. 3.

4.When chain tension adjustment is completed,

retighten the bolt securing the chain cover.

CAUTION

Due to the sharpness of the chain, protect your hands when checking the tension or servicing.

CUTTING PROCEDURES

1. General cutting procedures

(1)Switch ON the power while keeping the saw slightly away from the wood to be cut. Start sawing only after the unit has reached full speed.

(2)When sawing the slender piece of wood, press the base section of the guide bar against the wood and saw downward as shown in Fig. 4.

(3)When sawing a thick piece of wood, press the spike on the front section of the unit against the wood and cut it with lever action while using the spike as a fulcrum as shown in Fig. 5.

(4)When cutting wood horizontally, turn the unit body to the right so that the guide bar is below and hold the upper side of the side handle with your left hand. Hold the guide bar horizontally and place the spike that is on the front of the unit body on the lumber. Using the spike as a fulcrum, cut into the wood by turning the handle to the right. (Fig. 6)

(5)When cutting into wood from the bottom, touch the upper part of the guide bar to the wood lightly. (Fig. 7)

(6)In addition of careful study of the handling instructions, take practical instruction in the operation of the chain saw prior to use, or at least to practice working with the chain saw by cutting lengths of round timber on a sawing trestle.

(7)When cutting logs or timbers which are not

supported, support them properly not to move during cutting by a sawing trestle or another proper methods.

CAUTIONS

When cutting wood from the bottom, there is the danger that the unit body may pushed back toward the user if the chain strongly hits the wood.

Do not cut all the way through the wood by starting from the bottom since there is the danger of the guide bar flying up out of control when the cut is finished.

Always prevent the operating chain saw from

touching the ground or wire fences.

2. Branch cutting

(1)Cutting branches from a standing tree:

A thick branch should initially be cut off at a point away from the trunk of the tree.

First cut in about one third of the way from below, and then cut off the branch from above. Finally, cut off the remaining portion of the branch even with the trunk of the tree. (Fig. 8)

CAUTIONS

Always be careful to avoid falling branches.

Always be alert for chain saw recoil.

(2)Cutting branches from fallen trees:

First cut off branches that do not touch the ground, then cut off those which touch the ground. When cutting thick branches that touch the ground, first cut in about half of the way from above, then cut

the branch off from below. (Fig. 9)

CAUTIONS

When cutting off branches which touch the ground, be careful that the guide bar does not become bound by pressure.

In the final stage of cutting, beware of the log

suddenly rolling.

3.Log cutting

When cutting a log positioned as shown in Fig. 10, first cut in about one third of the way from below, then cut down all the way from above.

When cutting a log that straddles a hollow as shown

in Fig. 11, first cut in about two thirds of the way from above, then cut upward from below.

CAUTIONS

Be careful that the guide bar does not become bound in the log by pressure.

When working on inclined ground, be sure to stand

on the uphill side of the log. If you stand on the downhill side, the cut-off log may roll toward you.

4. Felling trees:

(1)Undercut (q as shown in Fig. 12):

Make undercut facing direction which you want tree to fall.

Depth of undercut should be 1/3 of tree’s diameter. Never fell trees without proper undercut.

(2)Backcut (w as shown in Fig. 12):

Make backcut about 5 cm above and parallel to the horizontal undercut.

If the chain is bound during cutting, stop the saw

and use wedges to free form it. Do not cut through the tree.

CAUTIONS

Trees should not be felled in a manner that would endanger any person, strike any utility line or cause any property damage.

Be sure to stand on the uphill side of the terrain as the tree is likely to roll or slide downhill after it is felled.

SHARPENING OF CHAIN BLADE

CAUTION

Ensure the power source has been disconnected from the tool before performing the steps below. Wear gloves to protect your hands.

Dull and worn chain blades will decrease the efficiency of the tool and place unnecessary overload on the motor and various parts of the machine. In order to maintain optimum efficiency, it is necessary to check the chain blades often and keep them properly sharpened and adjusted. Blade sharpening and depth gauge adjustment should be accomplished at the center of the guide bar with the chain properly mounted to the machine.
