GENERAL SAFETY RULES

INTENDED USE

The chainsaw is designed for cutting branches, trunks, logs and beams. It is only
designed to cut wood and to be used outdoors.

Do not use the chainsaw for other purposes not listed above.The chainsaw is not to
be used for professional tree services. It is not to be used by children or by persons
not wearing adequate personal protective equipment and clothing.

For safe operation, read and understand all instructions before using the chainsaw.
Follow all safety instructions. Failure to follow all safety instructions listed below can
result in serious personal injury.

 Know your tool. Read the operator’s manual carefully. Learn the saw’s

applications and limitations as well as the specific potential hazards related to the
tool. We recommend you attend a professional training course to increase your
awareness and proficiency in all chainsaw operations.

 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 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 the saw. As a
chainsaw user, you should take every step to keep your cutting jobs free from
accident and injury.

 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 when the engine is running.

Place your right hand on the rear handle and your left hand on the front handle with
your thumbs and fingers encircling the chainsaw handles. A firm grip together with
a stiff left arm will help you maintain control of the saw if kickback occurs.

 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, fence or any other obstruction
that could be hit while you are operating the saw.

 Always cut with the engine running at full speed. Fully squeeze the throttle trigger

and maintain a steady cutting speed.
 Do not overreach or cut above chest 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

JCB-CS38_960488008-01_Manual_final_ OEM licence.indd 2JCB-CS38_960488008-01_Manual_final_ OEM licence.indd 2 12/3/2010 5:58:23 PM12/3/2010 5:58:23 PM

equivalent.

 Do not operate a chainsaw with one hand. Serious injury to the operator, helpers,

bystanders may result from one-handed operation. A chainsaw is intended for two­handed use.

 Do not operate a chainsaw when you are exhausted. Fatigue causes

carelessness. Be more cautious before rest periods and towards the end of your
shift. Never operate a chainsaw when under the influence of medication, drugs or
alcohol.

 Use safety footwear. Do not wear loose clothing. Wear protective gloves and

clothing, and eye, hearing and head protection devices.

 Heavy protective clothing may increase operator fatigue, which could lead to

heat stroke. During hot and humid weather, heavy work should be scheduled for

early morning or late afternoon hours when temperatures are cooler.

 Do not stand on any unstable surface while using the chainsaw, such as ladders,

scaffolds, trees, etc. Always keep a sound and firm footing.

 Use caution when handling fuel. Move the chainsaw at least 10 m from the fuelling

point before starting the engine.

 Do not allow other persons to be near the chainsaw when starting or cutting

with the chainsaw. 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.
 Always carry the chainsaw with the engine stopped and the brake engaged,

the guide bar and saw chain to the rear and the silencer away from your body. When
transporting the chainsaw, use the appropriate guide bar scabbard.

 Do not operate a chainsaw 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 chainsaw down. Do not leave the engine

running unattended. As an additional safety precaution, apply the chain brake prior
to setting down the saw.

 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 spring back so that you will

not be struck when the tension in the wood fibres is released.

 Keep the handles dry, clean, and free of lubricant or fuel mixture.
 Beware of carbon monoxide poisoning. Operate the chainsaw only in well-

ventilated areas.

 Do not climb a tree to use the chainsaw, unless you have been specifically

trained to do so.

 Do not operate the chainsaw from a ladder; this is extremely dangerous.
 All chainsaw service, other than the items listed in the instruction manual and all

maintenance should be performed by competent chainsaw service personnel. (For
example, 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 and subsequently could cause the flywheel to burst.)

 Always have a fire extinguisher available when using a chainsaw.
 Use only the replacement guide bars and low kickback chains specified for

the saw.

 Do not adapt the powerhead to a bow guide or use it to power any attachments

or devices not listed for the saw.

 The petrol-powered saw is intended for infrequent use by homeowners, cottagers

and campers, and for such general applications as clearing, pruning, cutting
firewood, etc. It is not intended for prolonged use. Prolonged periods of operation
can cause circulatory (white finger) problems in the user’s hands due to vibration.
For such use, it may be appropriate to use a saw having an anti-vibration feature.

 Save these instructions. Refer to them frequently and use to instruct other users.

If you loan someone the tool, loan them these instructions also.

ADDITIONAL SAFETY RULES FOR YOUR CHAINSAW

 Do not cut vines and/or small underbrush (a diameter of less than 3 in.).
 Silencer surfaces are very hot during and immediately after operation of the

chainsaw; keep all body parts away from the silencer. Serious burns may occur if

contact is made with the silencer.

 Always hold the chainsaw with both hands when the engine is running. Use

a firm grip with thumbs and fingers encircling the chainsaw handles.

 Never let anyone use the chainsaw who has not received adequate

instructions in its proper use. This applies to rentals as well as privately-owned

saws.

 Before you start the engine, make sure the saw chain is not contacting any

object.

 Wear snug-fitting clothing. Always wear heavy, long trousers, boots and gloves.

Do not wear jewellery, shorts, sandals or go barefoot. Loose clothing could be
drawn into the engine or catch the chain or underbrush. Wear overalls, jeans or
chaps made of cut-resistant material or that contain cut-resistant inserts. Secure
hair so that it is above shoulder length.

WARNING

Wear safety clothing which is designed for chainsaw operators.

 Wear non-slip safety footwear and heavy-duty gloves to improve your grip and

to protect your hands.

 Wear eye protection which is marked to comply with BS EN166, as well as

hearing and head protection, when operating this equipment.

 Keep bystanders and animals out of the work area. Do not allow other persons

to be nearby during starting or cutting with the chainsaw.

Note: The size of the work area depends on the job being performed as well as
the size of the tree or work piece involved. For example, felling a tree requires a
larger work area than making other cuts (i.e. bucking cuts, etc.).

 Follow the sharpening and maintenance instructions for the saw chain.
 Never operate a chainsaw that is damaged, improperly adjusted or has been

modified (particularly guards or safety devices), or is not completely and
securely assembled. Be sure that the saw chain stops moving when the throttle

control trigger is released. If the saw chain moves at idle speed, the carburettor
may need adjusting. If the saw chain still moves at idle speed after adjustment has
been made, contact an authorized service centre for adjustment and discontinue
use until the repair is made.

 Do not smoke during refueling.

JCB-CS38_960488008-01_Manual_final_ OEM licence.indd 5JCB-CS38_960488008-01_Manual_final_ OEM licence.indd 5 12/3/2010 5:58:27 PM12/3/2010 5:58:27 PM

 To reduce the risk of fire and burn injury, handle fuel with care. It is highly

flammable.

 Mix and store fuel in a container approved for petrol.
 Mix fuel outdoors where there are no risks from sparks or flames.
 Select bare ground, stop the engine, and allow it to cool before refuelling.
 Loosen the fuel cap slowly to release any pressure and to keep fuel from escaping

around the cap.

 Tighten the fuel cap securely after refuelling.
 Wipe spilled fuel from the unit. Move 10 m away from refuelling site before starting

engine.
 NEVER attempt to burn off spilled fuel under any circumstances.
 The product is very noisy when operating. To prevent long term hearing damage,

wear hearing protection and keep other persons at least 15 m away from the work

area. Operating similar tools nearby increases risk of injury.
 Use of hearing protection reduces the ability to hear warnings (shouts or alarms). The

operator must pay extra attention to what is happening around the work area.
 Kickback is a dangerous reaction that can lead to serious injury. Do not rely

only on the safety devices provided with the saw. As a chainsaw user, you must take

special safety precautions to help keep your cutting jobs free from accident or injury.

Additional risks

Even when using the chainsaw as intended, there still remains additional risk of harm
which cannot be fully prevented. The following list of potential hazards should be read
and understood. You should pay extra attention and care to these items to reduce the
risk of injury.

 Contact with exposed cutting teeth and saw chain.
 Access to rotating parts (the saw chain).
 Unexpected, abrupt movement (kickback) of the guide bar.
 Flying chain parts (thrown off or broken).
 Flying material (cut from the work piece).
 Inhalation of saw dust and particles or emissions from the petrol engine.
 Skin contact with petrol / oil.
 Loss of hearing if no hearing protective equipment is worn during use.

WARNING

If any parts are damaged or missing, do not operate the tool until the parts are replaced.
Failure to heed this warning could result in serious personal injury.

WARNING

Do not attempt to modify the product or create accessories not recommended for
use with the product. Any such alteration or modification is misuse and could result in
hazardous condition leading to possible serious personal injury.

WARNING

Before first use, it is essential that you ensure the bar and chain have not become
loose in transit. Never operate a chainsaw with incorrectly adjusted chains. Failure to
follow these steps could result in severe personal injury.

ADJUSTING THE CHAIN TENSION

See Figures 2-3, 37, 42-45.

WARNING

Never touch or adjust the chain while the motor is running. The saw chain is very sharp.
Always wear protective gloves when performing maintenance on the chain.

1. Stop the engine before setting the chain tension.

2. Slightly loosen the clutch cover lock knob by pressing in and rotating counter
clockwise (Figure 37).

3. Turn the chain tension dial clockwise to tension the chain (Figure 44).
Note: A cold chain is correctly tensioned when there is no slack on the underside

of the guide bar, the chain is snug, and it can be turned by hand without binding.

4. Re-tension the chain whenever the fl ats on the drive links hang out of the bar
groove (Figure 3).

Note: During normal saw operation, the temperature of the chain increases. The
drive links of a correctly tensioned warm chain will hang approximately 1.2 mm out
of the bar groove. The tip of the combination wrench can be used as a guide to help
determine the correct warm chain tension.

Note: New chains tend to stretch; check the chain tension frequently and tension
as required. This applies for a NEW tool.

5. Lift the tip of the guide bar up to check for sag (Figure 43).

6. Release the tip of the guide bar and turn the chain tension dial clockwise. Repeat
this process until the sag does not exist.

7. Hold the tip of the guide bar up and tighten the clutch cover lock knob securely.
The chain is correctly tensioned when there is no sag on the underside of the
guide bar, the chain is snug, but it can be turned by hand without binding. Ensure
that the chain brake is not set.

Note: If chain is too tight, it will not rotate. Loosen the clutch cover lock knob by
pressing in and slightly rotating counter clockwise, then rotate the chain tension
dial counter clockwise. Lift the tip of the guide bar up and re-tighten the clutch
cover lock knob securely. Ensure that the chain will rotate without binding.

CAUTION

A chain tensioned while warm may be too tight upon cooling.

vapors.

 Do not let petrol or lubricant come in contact with your skin. If comes in contact with

your skin, wash immediately with soap and plenty of water.

 Keep petrol and lubricant away from your eyes. If petrol or lubricant comes in

contact with your eyes, wash them immediately with clean water. If irritation sill
exists, see a doctor immediately.

 Clean up spilled petrol immediately.

TO MIX THE FUEL

 The product is powered by a 2-cycle engine and requires pre-mixing petrol with

2-cycle lubricant. Pre-mix unleaded petrol and 2-cycle engine lubricant in a clean
container approved for petrol.

 The engine is certified to operate on unleaded petrol intended for automotive use

with an octane rating of 91 or higher.

 Do not use any type of pre-mixed petrol/lubricant from fuel service stations, such

as the pre-mixed petrol/lubricant intended for use in mopeds, motorcycles, etc.

 Use high quality 2-cycle self-mixing lubricant for air-cooled engines. Do not use

automotive lubricant or 2-cycle outboard lubricant.

 Mix 2% lubricant into the petrol. This is a 50:1 ratio.

1 l + 20 ml =
2 l + 40 ml =
3 l + 60 ml = 50:1 (2%)
4 l + 80 ml =
5 l + 100 ml =

 Mix the fuel thoroughly each time before fueling.
 Mix in small quantities. Do not mix quantities more than the amount to use in a 30-

day period. A 2-cycle lubricant containing a fuel stabilizer is recommended.

Note: Fuel system damage or performance problems resulting from the use of

an oxygenated fuel containing more than the percentage of oxygen stated previ­ously are not covered under warranty.

TO FILL THE TANK

See Figure 5.

1. Clean surface around the fuel cap to prevent contamination.

2. Loosen the fuel cap slowly.

3. Carefully pour the fuel mixture into the tank. Do not spill.

4. Prior to replacing the fuel cap, clean and inspect the gasket.

5. Immediately replace and tighten the fuel cap. Wipe up any fuel spillage.

Note: It is normal for smoke to emit from a new engine during and after first use.

ADDING BAR AND CHAIN LUBRICANT

See Figure 6.

The bar and chain lubricant is designed for chains and chain oilers, and is formulated
to perform over a wide temperature range with no dilution required. The chainsaw
should use approximately one tank of lubricant per tank of fuel.

Note: Do not use dirty, used or otherwise contaminated lubricants. Damage may

occur to the lubricant pump, bar or chain.

 Carefully pour the bar and chain lubricant into the lubricant tank.
 Fill the lubricant tank every time you fuel the engine.

OPERATING THE CHAIN BRAKE

See Figures 7-8.

Check the operating condition of the chain brake prior to each use.

 Engage the chain brake by rotating your left hand around the front handle, allowing

the back of your hand to push the chain brake lever/hand guard toward the bar
while the chain is rotating rapidly. Be sure to maintain both hands on the saw
handles at all times.

 Reset the chain brake back into the “Run” position by grasping the top of the chain

brake lever/hand guard and pulling toward the front handle until you hear a click.

WARNING

If the chain brake does not stop the chain immediately, or if the chain brake will not
stay in the “Run” position without assistance, take the saw to an authorised service

JCB-CS38_960488008-01_Manual_final_ OEM licence.indd 17JCB-CS38_960488008-01_Manual_final_ OEM licence.indd 17 12/3/2010 5:58:30 PM12/3/2010 5:58:30 PM

centre for repair.

STARTING AND STOPPING ENGINE

See Figures 7-14.

WARNING

Keep your body to the left of the chain line. Never straddle the saw or chain, or lean
past over the chain line.

 Place the chainsaw on level ground and ensure that no objects or obstructions are

within the immediate vicinity that could come in contact with the bar and chain.

 Hold the front handle firmly with your left hand and put your right foot onto the base

of the rear handle.

TO START A COLD ENGINE

1. Turn on the ignition switch.

2. Make sure the chain brake is in the “Run” position by pulling back on the lever/
hand guard.

3. Fully press and release the primer bulb at least 10 times.

4. Pull choke lever all the way out to “Start” position.

5. When the temperature is above 10°C, pull the starter grip until the engine attempts
to start, but no more than 3 times. When the temperature is below 10°C, pull the
starter grip until the engine attempts to start, but no more than 5 times.

6. Push choke lever to “Run” position. Pull starter grip until engine runs.
Note: Allow the saw to run in this position 15-30 seconds, depending upon the

temperature.

7. Depress the trigger release and squeeze and release the throttle trigger to return
the engine to idle after a total run time of at least 30 seconds.

Note: Failure to release partial throttle when chain brake lever is in the “Brake”

position will result in serious damage to the unit. Never squeeze and hold the throt­tle trigger while the chain brake is in the “Brake” position.

TO START A WARM ENGINE

1. Turn on the ignition switch.

2. Make sure the chain brake is in the “Run” position by pulling back on the lever/
hand guard.

3. Keep choke lever on “Run” position.

4. Pull starter grip until engine runs, but no more than 5 times. If engine does not start
after 5 pulls, use cold engine starting procedure.

5. Squeeze and release the throttle trigger to return the engine to idle.

TO STOP THE ENGINE

1. Release the throttle trigger and let the engine return to idle.

2. To stop the engine, move the ignition switch to the “Stop” (0) position. Do not put
the chainsaw on the ground when the chain is still moving. For additional safety , set
the chain brake when the saw is not in use.

3. In the event that the ignition switch will not stop the saw, pull the choke lever out
to the fully extended position “Full choke” and engage the chain brake to stop the
engine. If the ignition switch will not stop the saw when set to the “Stop” position,
have the ignition switch repaired before using the chainsaw again to prevent unsafe
conditions or serious injury.

Note: After using the saw , always relieve tank pressure by loosening then re-tight­ening the chain lubricant and fuel caps. Allow the engine to cool before storing.

ADJUSTING IDLE SPEED

See Figure 15.

 If the engine starts, runs and accelerates, but will not idle, turn the idle speed screw

“T” clockwise to increase idle speed to 2600~3600 rpm.

 If the chain turns at idle, turn the idle speed screw “T” counter clockwise to reduce

the idle RPM and stop the chain movement. If the saw chain still moves at idle
speed, contact an authorised service centre for adjustment and discontinue use
until the repair is made.

WARNING

THE SAW CHAIN SHOULD NEVER TURN AT IDLE. Serious personal injury may
result from the saw chain turning at idle.

PULL AND PUSH

See Figure 16.

The reaction force of the saw is always opposite to the direction the chain is moving.
The operator must be ready to control the PULL when cutting on the bottom edge of
the bar and the PUSH when cutting along the top edge.

KICKBACK PRECAUTIONS

See Figures 17-18.

Rotational kickback occurs when the moving chain contacts an object at the Kickback
Danger Zone of the guide bar. The result is a lightning-fast reverse reaction, which
kicks the guide bar up and back towards the operator. This reaction can cause loss of

JCB-CS38_960488008-01_Manual_final_ OEM licence.indd 19JCB-CS38_960488008-01_Manual_final_ OEM licence.indd 19 12/3/2010 5:58:30 PM12/3/2010 5:58:30 PM

control, which can result in serious injury.

PREPARING FOR CUTTING
PROPER GRIP ON HANDLES

See Figure 19.

 Wear non-slip gloves for maximum grip and protection.
 Hold the saw firmly with both hands. Always keep your left hand on the front handle

and your right hand on the rear handle so that your body is to the left of the chain
line.

WARNING

Never use a left-handed (cross-handed) grip or any stance that would place your body
or arm across the chain line.

 Maintain a proper grip on the saw whenever the engine is running. The fingers

should encircle the handle and the thumb wrapped under the handlebar. This grip
is least likely to be broken by a kickback or other sudden reaction of the saw. Any
grip in which the thumb and fingers are on the same side of the handle is dangerous
because a slight kick of the saw can cause loss of control.

WARNING

See Figure 20.

DO NOT operate the throttle trigger with your left hand and hold the front handle with
your right hand. Never allow any part of your body to be in the chain line while operating
a saw.

PROPER CUTTING STANCE

See Figure 21.

 Balance your weight with both feet on solid ground.
 Keep left arm with elbow locked in a “straight arm” position to withstand any kickback

force.
 Keep your body to the left of the chain line.
 Keep your thumb on the underside of the handlebar.

WORK AREA PRECAUTIONS

See Figure 22.

JCB-CS38_960488008-01_Manual_final_ OEM licence.indd 20JCB-CS38_960488008-01_Manual_final_ OEM licence.indd 20 12/3/2010 5:58:30 PM12/3/2010 5:58:30 PM

SL7 1TB
Customer Helpline 0845 600 5526 Monday to Friday 09.00 to 17.00
www.JCBdiy.com

 Cut only wood or materials made from wood.
 Never allow children to operate the saw. Do not allow persons to use this chainsaw

who have not read the operator’s manual or received adequate instructions for the
safe and proper use of the chainsaw.

 Keep helpers, bystanders, children and animals at a SAFE DISTANCE from the

cutting area. During felling operations, the safe distance should be at least twice
the height of the largest trees in the felling area. During bucking operations, keep a

minimum distance of 5 m between workers.
 Always cut with both feet on solid ground to prevent being pulled off balance.
 Do not cut above chest height as a saw held higher is difficult to control against

kickback forces.
 Do not fell trees near electrical wires or buildings. Leave this operation for

professionals.
 Cut only when visibility and light are adequate for you to see clearly.

BASIC OPERATING / CUTTING PROCEDURES

Practise cutting a few small logs using the following technique to get the “feel” of using
the saw before you begin a major sawing operation.

1. Take the proper stance in front of the wood with the saw idling.

2. Accelerate the engine to full throttle just before entering the cut by squeezing the
throttle trigger.

3. Begin cutting with the saw against the log.

4. Keep the engine at full throttle the entire time you are cutting.

5. Allow the chain to cut for you; exert only light downward pressure. Forcing the cut
could result in damage to the bar, chain or engine.

6. Release the throttle trigger as soon as the cut is completed, allowing the engine to
idle. Running the saw at full throttle without a cutting load can result in unnecessary
wear to the chain, bar and engine.

7. Do not put pressure on the saw at the end of the cut as this may cause the saw to
drop in an unsafe manner.

DO NOT FELL TREES IN HAZARDOUS CONDITIONS

WARNING

Do not fell trees during periods of high wind or heavy rain. Wait until the hazardous
weather has ended. When felling a tree, it is important that you heed the following
warnings to prevent possible serious injury.

 Do not cut down trees having extreme lean or large trees with rotten limbs, loose bark

or hollow trunks. Have these trees pushed or dragged down with heavy equipment,

then cut them up.
 Do not cut trees near electrical wires or buildings.
 Check the tree for damaged or dead branches that could fall and hit you during

felling.
 Periodically glance at the top of the tree during the back cut to ensure the tree is

going to fall in the desired direction.
 If the tree starts to fall in the wrong direction, or if the saw gets caught or hung up

during the fall, leave the saw and save yourself!

PROPER PROCEDURE FOR TREE FELLING

See Figures 23-26.

1. Pick your escape route (or routes in case the intended route is blocked). Clear the
immediate area around the tree and make sure there are no obstructions in your
planned path of retreat. Clear the path of safe retreat approximately 135° from the
planned line of fall.

2. Consider the force and direction of the wind, the lean and balance of the tree, and
the location of large limbs. These things infl uence the direction in which the tree will
fall. Do not try to fell a tree along a line different from its natural line of fall.

3. Cut a notch about 1/3 the diameter of the trunk in the side of the tree. Make the
notch cuts so they intersect at a right angle to the line of fall. This notch should be
cleaned out to leave a straight line. To keep the weight of the wood off the saw,
always make the lower cut of the notch before the upper cut.

4. Make the back cut level and horizontal, and at a minimum of 2 in. above the
horizontal cut of the notch.

Note: Never cut through to the notch. Always leave a band of wood between the
notch and back cut (approximately 2 in. or 1/10 the diameter of the tree). This is
called a “hinge” or “hinge wood.” It controls the fall of the tree and prevents slipping
or twisting or shoot back of the tree off the stump.

5. On large diameter trees, stop the back cut before it is deep enough for the tree to
either fall or settle back on the stump. Then insert soft wooden or plastic wedges

JCB-CS38_960488008-01_Manual_final_ OEM licence.indd 22JCB-CS38_960488008-01_Manual_final_ OEM licence.indd 22 12/3/2010 5:58:30 PM12/3/2010 5:58:30 PM

SL7 1TB
Customer Helpline 0845 600 5526 Monday to Friday 09.00 to 17.00
www.JCBdiy.com

into the cut so they do not touch the chain. Drive wedges in, little by little, to help
jack the tree over.

6. As the tree starts to fall, stop the chainsaw and put it down immediately. Retreat
along the cleared path, but watch the action in case something falls your way.

WARNING

Never cut through to the notch when making a back cut. The hinge controls the fall of
the tree; this is the section of wood between the notch and back cut.

REMOVING BUTTRESS ROOTS

See Figure 27.

A buttress root is a large root extending from the trunk of the tree above the ground.
Remove large buttress roots prior to felling. Make the horizontal cut into the buttress
first, followed by the vertical cut. Remove the resulting loose section from the work area.
Follow the correct tree felling procedure after you have removed the large buttress
roots.

BUCKING

See Figure 28.

Bucking is the term used for cutting a felled tree to the desired log length.

 Cut only one log at a time.
 Support small logs on a saw horse or another log while bucking.
 Keep a clear cutting area. Make sure that no objects can contact the guide bar nose

and chain during cutting; this can cause kickback.

 During bucking operations, stand on the uphill side so that the cut-off section of the

log cannot roll over you.

 Sometimes it is impossible to avoid pinching (with just standard cutting techniques)

or difficult to predict which way a log will settle when cut.

BUCKING WITH A WEDGE

See Figure 29.

If the wood diameter is large enough for you to insert a soft bucking wedge without
touching the chain, you should use the wedge to hold the cut open to prevent pinching.

JCB-CS38_960488008-01_Manual_final_ OEM licence.indd 23JCB-CS38_960488008-01_Manual_final_ OEM licence.indd 23 12/3/2010 5:58:30 PM12/3/2010 5:58:30 PM

SL7 1TB
Customer Helpline 0845 600 5526 Monday to Friday 09.00 to 17.00
www.JCBdiy.com

BUCKING LOGS UNDER STRESS

See Figure 30.

Make the first bucking cut 1/3 of the way through the log and finish with a 2/3 cut on the
opposite side. As you cut the log, it will tend to bend. The saw can become pinched or
hung in the log if you make the first cut deeper than 1/3 of the diameter of the log.

Give special attention to logs under stress to prevent the bar and chain from pinching.

OVERBUCKING

See Figure 31.

Begin on the top side of the log with the bottom of the saw against the log; exert light
downward pressure. Note that the saw will tend to pull away from you.

UNDERBUCKING

See Figure 32.

Begin on the underside of the log with the top of the saw against the log; exert light
upward pressure. During underbucking, the saw will tend to push back at you. Be
prepared for this reaction and hold the saw firmly to maintain control.

BRANCH TRIMMING AND PRUNING

See Figures 33-34.

 Work slowly, keeping both hands on the saw with a firm grip. Maintain secure footing

and balance.
 Keep the tree between you and the chain while limbing.
 Do not cut from a ladder. This is extremely dangerous. Leave this operation for

professionals.
 Do not cut above chest height. A saw held higher than chest height is difficult to

control against kickback.

WARNING

Never climb into a tree to limb or prune. Do not stand on ladders, platforms, a log or in
any position which can cause you to lose your balance or control of the saw.

 When pruning trees, it is important not to make the flush cut next to the main limb or

trunk until you have cut off the limb further out to reduce the weight. This prevents

stripping the bark from the main member.
 Underbuck the branch 1/3 through for your first cut.

JCB-CS38_960488008-01_Manual_final_ OEM licence.indd 24JCB-CS38_960488008-01_Manual_final_ OEM licence.indd 24 12/3/2010 5:58:31 PM12/3/2010 5:58:31 PM

SL7 1TB
Customer Helpline 0845 600 5526 Monday to Friday 09.00 to 17.00
www.JCBdiy.com

 Overbuck the branch to drop it.
 Finish by cutting smoothly and neatly against the main member so the bark will grow

back to seal the wound.

WARNING

If the limbs to be pruned are above chest height, hire a professional to perform the
pruning.

CUTTING SPRINGPOLES

See Figure 35.

A springpole is any log, branch, rooted stump or sapling which is bent under tension by
other wood so that it springs back if the wood holding it is cut or removed. On a felled
tree, a rooted stump has a high potential of springing back to the upright position during
the bucking cut to separate the log from the stump. Watch out for springpoles — they
are dangerous.

WARNING

Springpoles are dangerous and could strike the operator, causing the operator to lose
control of the chainsaw. This could result in severe or fatal injury to the operator.

JCB-CS38_960488008-01_Manual_final_ OEM licence.indd 25JCB-CS38_960488008-01_Manual_final_ OEM licence.indd 25 12/3/2010 5:58:31 PM12/3/2010 5:58:31 PM

MAINTENANCE

WARNING

When servicing, use only identical replacement parts. Use of any other parts may
create a hazard or cause product damage.

WARNING

Always wear safety goggles or safety glasses with side shields during power tool
operation or when blowing dust. If operation is dusty, also wear a dust mask.

GENERAL MAINTENANCE

Avoid using solvents when cleaning plastic parts. Most plastics are susceptible to
damage from various types of commercial solvents and may be damaged by their use.
Use clean cloths to remove dirt, dust, lubricant, grease, etc.

WARNING

Do not at any time let brake fluids, petrol, petroleum-based products, penetrating
lubricants, etc., come in contact with plastic parts. Chemicals can damage, weaken or
destroy plastic which may result in serious personal injury.

LUBRICATION

All of the bearings in this product are lubricated with a sufficient amount of high grade
lubricant for the life of the unit under normal operating conditions. Therefore, no further
lubrication is required.

REPLACING THE GUIDE BAR AND CHAIN

See Figures 36-45.

DANGER

Never start the engine before installing the guide bar, chain, clutch cover and clutch
drum. Without all these parts in place, the clutch can fly off or explode, exposing the
user to possible serious injury.

WARNING

To avoid serious personal injury, read and understand all the safety instructions in this
section.

 Always place the switch in the “Stop” (0) position before you work on the saw.

 Make sure the chain brake is not set by pulling the chain brake lever/hand guard

towards the front handle to the “Run” position.

JCB-CS38_960488008-01_Manual_final_ OEM licence.indd 26JCB-CS38_960488008-01_Manual_final_ OEM licence.indd 26 12/3/2010 5:58:31 PM12/3/2010 5:58:31 PM

SL7 1TB

www.JCBdiy.com

Note: When replacing the guide bar and chain, always use the specified bar and
chain.

 Wear gloves when handling the chain and bar. These components are sharp and

may contain burrs.

1. Press in on the clutch cover lock knob and rotate counter clockwise until the
clutch cover can be removed.

2. Remove the bar and chain from the mounting surface.

3. Remove the old chain from the bar.

4. Lay out the new saw chain in a loop and straighten any links. The cutters should

face in the direction of chain rotation. If they face backwards, turn the loop over.

5. Place the chain drive links into the bar groove as shown.

6. Position the chain so there is a loop at the back of the bar.

7. Hold the chain in position on the bar and place the loop around the sprocket.

8. Fit the bar fl ush against the mounting surface so that the bar studs are in the

long slot of the bar.

9. Replace the clutch cover ensuring that the adjusting pin in the clutch cover is in
the bar chain tensioning pin hole.

10. Replace the clutch cover and rotate clutch cover lock knob just enough to hold
the cover in position.

Note: The bar must be free to move for tension adjustment.

11. Remove all slack from the chain by rotating the chain tension dial clockwise

until the chain seats snugly against the bar with the drive links in the bar groove.

12. Lift the tip of the guide bar up to check for sag.

13. Release the tip of the guide bar and turn the chain tension dial clockwise.

Repeat this process until sag does not exist.

14. Hold the tip of the guide bar up and tighten the clutch cover lock knob securely.
The chain is correctly tensioned when there is no sag on the underside of the
guide bar, the chain is snug, but it can be turned by hand without binding.
Ensure that the chain brake is not set.

Note: If chain is too tight, it will not rotate. Loosen the clutch cover lock knob by
pressing in and slightly rotating counter clockwise, then rotate the chain tension
dial counter clockwise. Lift the tip of the guide bar up and re-tighten the clutch
cover lock knob securely. Ensure that the chain will rotate without binding.

CHAIN MAINTENANCE

See Figures 45-47.

 Check that the switch is in the “Stop” (0) position before you work on the saw.
 Use only a low-kickback chain on this saw. This fast-cutting chain provides

kickback reduction when properly maintained.

JCB-CS38_960488008-01_Manual_final_ OEM licence.indd 27JCB-CS38_960488008-01_Manual_final_ OEM licence.indd 27 12/3/2010 5:58:31 PM12/3/2010 5:58:31 PM

SL7 1TB
Customer Helpline 0845 600 5526 Monday to Friday 09.00 to 17.00
www.JCBdiy.com

 For smooth and fast cutting, maintain the chain properly. The chain requires

sharpening when the wood chips are small and powdery. The chain must be
forced through the wood during cutting or the chain will cut to one side. During
maintenance of the chain, consider the following:

 Improper filing angle of the side plate can increase the risk of severe kickback.
 Raker (depth gauge) clearance.

 Too low increases the potential for kickback.
 Not low enough decreases cutting ability.

 If the cutter teeth hit hard objects such as nails and stones, or are abraded

by mud or sand on the wood, have an authorised service centre sharpen the
chain.

Note: Inspect the drive sprocket for wear or damage when replacing the chain.

If signs of wear or damage are present in the areas indicated, have the drive
sprocket replaced by an authorised service centre.

Note: If you do not fully understand the correct procedure for sharpening the

chain after reading the instructions that follow, have the saw chain sharpened by
an authorised service centre or replace with a recommended low-kickback chain.

SHARPENING THE CUTTERS

See Figures 48-51.

Be careful to file all cutters to the specified angles and to the same length, as fast
cutting can only be obtained when all cutters are uniform.

WARNING

The saw chain is very sharp. Always wear protective gloves when performing
maintenance to the chain to prevent serious personal injury.

1. Tension the chain prior to sharpening.

2. Use a 5/32 in. (4 mm) diameter round fi le and holder. Do all of your fi ling at the
midpoint of the bar.

3. Keep the fi le level with the top plate of the tooth. Do not let the fi le dip or rock.

4. Use light but fi rm pressure. Stroke towards the front corner of the tooth.

5. Lift the fi le away from the chain tooth on each return stroke.

6. Put a few fi rm strokes on every tooth. File all left hand cutters in one direction.
Then move to the other side and fi le the right hand cutters in the opposite direction.

7. Remove fi lings from the fi le with a wire brush.

JCB-CS38_960488008-01_Manual_final_ OEM licence.indd 28JCB-CS38_960488008-01_Manual_final_ OEM licence.indd 28 12/3/2010 5:58:31 PM12/3/2010 5:58:31 PM

Note: A dull or improperly sharpened chain can cause excessive engine speed
during cutting, which may result in severe engine damage.

WARNING

Improper chain sharpening increases the potential of kickback.

WARNING

Failure to replace or repair a damaged chain can cause serious injury.

TOP PLATE FILE ANGLE

See Figure 52.

 CORRECT 30° – file holders are marked with guide marks to align file properly to

produce correct top plate angle.
 LESS THAN 30° – for cross cutting.
 MORE THAN 30° – feathered edge dulls quickly.

SIDE PLATE ANGLE

See Figure 53.

 CORRECT 80° – produced automatically if you use the correct diameter file in the

file holder.
 HOOK – “grabs” and dulls quickly; increases the potential of kickback. Results from

using a file with a diameter too small or a file held too low.
 BACKWARD SLOPE – needs too much feed pressure; causes excessive wear to

the bar and chain. Results from using a file with a diameter too large or file held

too high.

MAINTAINING DEPTH GAUGE CLEARANCE

See Figures 54-56.

 Maintain the depth gauge at a clearance of 0.64 mm. Use a depth gauge tool for

checking the depth gauge clearances.
 Every time the chain is filed, check the depth gauge clearance.
 Use a flat file and a depth gauge jointer to lower all gauges uniformly. Use a 0.64

mm depth gauge jointer. After lowering each depth gauge, restore original shape

by rounding the front. Be careful not to damage adjoining drive links with the edge

of the file.

 Depth gauges must be adjusted with the flat file in the same direction the adjoining

cutter was filed with the round file. Use care not to contact cutter face with flat file

when adjusting depth gauges.

MAINTAINING THE GUIDE BAR

See Figure 57.

 Check that the switch is in the “Stop” (0) position on the saw.
 In every week of use, turn over the guide bar on the saw to distribute the wear for

maximum bar life. The bar should be cleaned every day of use and checked for

wear and damage. Feathering or burring of the bar rails is a normal process of bar

wear. Such faults should be smoothed with a file as soon as they occur.
 A bar with any of the following faults should be replaced:

 Wear inside the bar rails that permits the chain to lay over sideways
 Bent guide bar
 Cracked or broken rails
 Spread rails

 Lubricate guide bar sprockets weekly. Using a grease syringe, lubricate weekly in

the lubricating hole. Turn the guide bar and check that the lubrication holes and

chain groove are free from impurities.

CLEANING THE AIR FILTER

See Figures 58-59.

1. Activate the chain brake.

2. Remove the two screws holding the engine cover.

3. Lift the front of the engine cover past chain brake lever.

4. Lift the back of the engine cover past the handle.

5. Before removing the air fi lter from the carburettor, blow or brush as much loose dirt
and sawdust from around the carburettor and chamber as possible.

Note: Make sure to pull the choke rod out to keep the carburettor from being con­taminated.

6. Lift the air fi lter off the air fi lter base.

7. Choose one of the following cleaning options:

 To lightly clean, tap the filter against a smooth, flat surface to dislodge most saw

dust and dirt particles.

 After every 5 hours of operation, clean in warm soapy water, rinse and let dry

completely. Replace with a new filter after every 25 hours of use.
