Safety Rules for Tree Service Chain Saw
This chain saw for tree service is a specialized chain-saw of
limited weight designed for use by a trained and competent
operator for pruning and dismantling standing tree crowns.
A trained operator is a person who has competence and
knowledge in:
- the use and particular hazards associated with using a chain-
saw (for tree service work),
- the precautions to be taken to limit these hazards including
wearing recommended personal protective equipment (PPE).
Due to the special compact handle design, there is an increa-
sed risk of injury.
For this reason these special chainsaws should be used only
for work in a tree by persons who are trained in special cut-
ting and working techniques and who are properly secured
(lift bucket, ropes, safety harness).
For all other cutting work forestry chain saws (with wider
spaced handles) must be used.
In addition to the safety instructions listed in the following
pages of the manual, when using a tree service chain saw
take special attention to the following instructions:
• The specially shaped handgrip on the machine calls for parti-
cular care when dealing with kickback.
• Extreme care should be taken at the end of a cutting operation
in relation to the machine suddenly dropping. This eventuality is
difficult to control with this type of handgrip.
• Attention should be paid to chain sliding. Instead of penetrating
the tree trunk, the chain may slide forward and the operator will
not be able to fully control this action.
• Tree maintenance operators must be trained in the correct ope-
rative techniques concerning safety at work, i.e.: headgear,
safety harnesses, cables and spring-clips, as well as all of the
other safety devices that are normally used and must be trained
professionally in tree climbing.
• Pay attention to wires while working; always keep distance from
them.
• Release machine from hook point while refuelling.
Working with Tree Service Chain saws from a Rope and
Harness
This chapter sets out working practices to reduce the risk of injury
from tree service chain saws when working at height from a rope
and harness. These practices should not be regarded as a substi-
tute for formal training.
General requirements working at height
Operators of tree service chain saws working at height from a
rope and harness should never work alone. A competent ground
worker trained in appropriate emergency procedures should assi-
st them.
Operators of tree service chain saws for this work should be trai-
ned in general safe climbing and work positioning techniques and
should be properly equipped with harnesses, ropes, strops, kara-
biners and other equipment for maintaining secure and safe
working positions for both themselves and the saw.
Preparing to use the saw in the tree
The chain saw should be checked, fueled, started and warmed up
by the ground worker before it is sent up to the operator in the tree.
The chain saw should be fitted with a suitable strop for attaching
to the operator’s harness (Fig. 1):
a) secure the strop around the attachment point on the rear of
the saw (Fig. 2);

en
8
b) provide suitable karabiners to allow indirect (i.e. via the strop)
and direct attachment (i.e. at the attachment point on the saw)
of saw to the operator’s harness;
c) ensure the saw is securely attached when it is being sent up
to the operator;
d) ensure the saw it secured to the harness before it is discon-
nected from the means of ascent.
Stop the machine when it is attached to the operator.
The saw should only be attached to the recommended attachment
points on the harness. These may be at mid-point (front or rear) or
at the sides.Where possible, attaching the saw to centre rear mid-
point will keep it clear of climbing lines and support its weight cen-
trally down the operator’s spine (Fig. 3).
When moving the saw from any attachment point to another, ope-
rators should ensure it is secured in the new position before relea-
sing it from the previous attachment point.
Using the chain saw in the tree
An analysis of accidents with these saws during tree service ope-
rations shows the primary cause as being inappropriate one-han-
ded use of the saw. In the vast majority of accidents, operators fail
to adopt a secure work position which allows them to hold both
handles of the saw. This results in an increased risk of injury due
to:
- not having a firm grip on the saw if it kicks back;
- a lack of control of the saw such that it is more liable to contact
climbing lines and operators body (particularly the left hand and
arm)
- losing control from insecure work position resulting in contact
with the saw (unexpected movement during operation of the
saw)
Securing the work position for two-handed use
To allow the operator to hold the saw with both hands, the opera-
tor should try to secure a work position where he or she is opera-
ting the saw at:
- hip level when cutting horizontal sections;
- solar plexus level when cutting vertical sections.
Where the operator is working close into vertical stems with a low
lateral force on his/her work position, then good footing may be all
that is needed to maintain a secure work position. However, as
operators move away from the stem, they will need to take steps
to remove or counteract the increasing lateral force by, for exam-
ple, a re-direct of the main line via a supplementary anchor point
or using an adjustable strop direct from the harness to a supple-
mentary anchor point (Fig. 4).
Gaining good footing at the working position can be assisted by
use of a temporary foot stirrup created from an endless sling
(Fig. 5).
Starting the saw in the tree
When starting the saw in the tree, the operator should:
a) apply the chain brake before starting;
b) hold saw on either the left or right of the body when starting:
1) on the left side hold the saw with either the left hand on the
front handle or the right hand on the rear handle and thru-
st the saw away from the body while holding the pull star-
ter cord in the other hand;
2) on the right side, hold the saw with the right hand on either
handle and thrust the saw away from the body while hol-
ding the pull starter cord in the left hand.

The chain brake should always be engaged before lowering a
running saw onto its strop.
Operators should always ensure that the saw has sufficient fuel
before undertaking critical cuts.
One-hand use of the chain saw
Operators should not use tree service chain saws one-handed in
place of unstable work positioning or in preference to a handsaw
when cutting small diameter wood at the branch tips.
Tree service chain saws should only be used one-handed where:
- the operator cannot gain a work position enabling two-handed
use; and
- they need to support their working position with one hand; and
- the saw is being used at full stretch, at right angles to and out
of line with the operator’s body (Fig. 6).
Operators should never:
- cut with the kickback zone at the tip of the chain saw guide bar
- ‘hold and cut’ sections
- attempt to catch falling sections
Freeing a trapped saw
If the saw should become trapped during cutting, operators
should:
- switch off the saw and attach it securely to the tree inboard (i.e.
towards the trunk side) of the cut or to a separate tool line;
- pull the saw from the kerf while lifting the branch as necessary;
- if necessary, use a handsaw or second chain saw to release
the trapped saw by cutting a minimum of 12 in. away from the
trapped saw.
Whether a handsaw or a chain saw is used to free a stuck saw,
the release cuts should always be outboard (toward the tips of the
branch), in order to prevent the saw being taken with the section.

SAFETY RULES
Basic Safety Precautions
• Read this manual carefully until you completely understand and
can follow all safety rules, precautions, and operating instruc-
tions before attempting to use the unit.
• Restrict the use of your saw to adult users who understand and
can follow safety rules, precautions, and operating instructions
found in this manual. Minors should never be allowed to use a
chainsaw.
• Do not handle or operate a chain saw when you are fatigued,
ill, or upset, or if you have taken alcohol, drugs, or medication.
You must be in good physical condition and mentally alert.
Chain saw work is strenuous. If you have any condition that
might be aggravated by strenuous work, check with your doctor
before operating a chain saw (Fig. 7). Be more cautious before
rest periods and towards the end of your shift.
• Keep children, bystanders, and animals a minimum of 35 feet
(10 meters) away from the work area. Do not allow other peo-
ple or animals to be near the chain saw when starting or ope-
rating the chain saw (Fig. 8).
• Major cases of chainsaw accidents happen when the chain hits
the operator.While working with the chainsaw, always use safety
protective approved clothing.The use of protective clothing does
not eliminate injury risks, but reduces the injury effects in case
of accident. Consult your trusted supplier to choose equipment
in compliance with legislation. The clothing must be proper and
not an obstacle. Wear adherent anti-cut clothing. Anti-cut
jackets (Fig. 9), dungarees (Fig. 9) and leggings are ideal.
Do not wear clothes, scarves, ties or bracelets that may get
stuck in wood or twigs. Tie up and protect long hair (example
with foulards, cap, helmets, etc.). Safety shoes or boots
having skid-proof sole and anti-piercing insert (Fig. 10).
Wear protective helmet (Fig. 11) in places where there can
be falling objects. Wear protective goggles or face screens!
Use protections against noises: for example noise reduc-
tion ear guards (Fig. 11) or earplugs. The use of protections
for the ear requests much more attention and caution, because
the perception of danger audio signals (screaming, alarms, etc.)
is limited. Wear anti-cut gloves (Fig. 12).
• Only loan your saw to expert users who are completely familiar
with saw operation and correct use. Give other users the
manual with operating instructions, which they have to read
before using the saw.
• Check the chain saw each day to ensure that each device,
whether for safety or otherwise, is functional.
• Never use a damaged, modified, or improperly repaired or
assembled chain saw. Do not remove, damage or deactivate
any of the safety devices. Only use bars of the length indicated
in the table (page 17). Always replace bar, chain, hand guard,
or chain brake immediately if it becomes damaged, broken or is
otherwise removed.
• Carefully plan your sawing operation in advance. Do not start
cutting until you have a clear work area, secure footing, and, if
you are felling trees, a planned retreat path.
• All saw service, other than the operations shown in the present
manual, have to be performed by competent personnel.
• The chain saw must only be used for cutting wood. It is unadvi-
sable to cut other types of material.
• It is unadvisable to hitch tools or applications to the P.t.o. that
are not specified by the manufacturer.

SAFETY RULES
Fuel Handling
WARNING: Gasoline is an extremely flammable fuel.
Use extreme caution when handling gasoline or fuel
mix. Do not smoke or bring any fire or flame near the
fuel or the chainsaw (Fig. 13).
•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 gasoline (Fig. 14).
• Mix fuel outdoors where there are no sparks or flames.
• Select bare ground, stop engine, and allow to cool before
refueling.
• Loosen fuel cap slowly to release pressure and to keep fuel
from escaping around the cap.
• Tighten fuel cap securely after refueling. Unit vibration can
cause an improperly tightened fuel cap to loosen or come off
and spill quantities of fuel.
• Wipe spilled fuel from the unit. Move 10 feet (3 m) away from
refueling site before starting engine (Fig. 15).
• Never attempt to burn off spilled fuel under any circumstances.
• Do not smoke while handling fuel or while operating the saw.
• Store fuel in a cool, dry, well ventilated place.
• Never place the saw in a combustible area such as dry leaves,
straw, paper, etc.
• Store the unit and fuel in an area where fuel vapors cannot
reach sparks or open flames from water heaters, electric
motors or switches, furnaces, etc.
• Never take the cap off the tank when the engine is running.
• Never use fuel for cleaning operations.
• Take care not to get fuel on your clothing.
• Don’t refuel when you are in a tree; refuel only on a secure
ground or on a platform.
Operation and Safety
WARNING: Always hold the chain saw with both
hands when the engine is running. Use a firm grip
with thumbs and fingers encircling the chain saw
handles (Fig. 16).
• Keep all parts of your body away from the saw chain when the
engine is running.
• Always carry the chain saw with the engine stopped and chain
brake engaged, the guide bar and saw chain to the rear, and
the muffler away from your body. When transporting your chain
saw, use the appropriate guide bar scabbard (Fig. 17). When
transporting in a vehicle, keep chain and bar covered with the
chain guard. Properly secure your saw to prevent turnover, fuel
spillage and damage to the saw.
• Apply chain brake prior to any repositioning of the operator in
the cutting area.
•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.
• Before you start the engine, make sure the saw chain is not
contacting any object. Never try to start the saw when the guide
bar is in a cut.
• Shut off the engine before setting down the saw. Do not leave
the engine running unattended.

SAFETY RULES
• As an additional safety precaution, apply the chain brake prior
to setting down the saw.
• Only use the chain saw in well-ventilated places, do not opera-
te the chain saw in explosive or flammable atmospheres or in
closed environments (Fig. 18). Beware of carbon monoxide poi-
soning.
• Do not operate saw from a ladder. Always cut in a safe position.
• Do not put pressure on the saw at the end of the cut. Applying
pressure can cause you to lose control when the cut is com-
pleted.
• Do not cut near electric cables.
• Keep the handles dry, clean, and free of oil or fuel mixture.
• When the chain saw is running, grip the front handle firmly with
your left hand and the back handle with your right hand (Fig.
16).
• When cutting a limb that is under tension, be alert for spring-
back so you will not be struck when the tension in the wood
fibre is released.
• Take great care when cutting small branches or shrubs which
can block the chain, be thrown back towards you or cause you
to lose your balance.
• Never cut with the chain saw above shoulder height (Fig. 19).
• Never start up the chain saw without the chain cover fitted.
Precautions Against Kickback
WARNING: Avoid kickback which can result in
serious injury. Kickback is the backward, upward or
sudden forward motion of the guide bar occurring
when the saw chain near the upper tip of the guide
bar contacts any object such as a log or branch, or
when the wood closes in and pinches the saw chain
in the cut. Contacting a foreign object in the wood
can also result in loss of chain saw control.
•Rotational Kickback can occur when the moving chain con-
tacts an object at the upper tip of the guide bar. This contact
can cause the chain to dig into the object, which stops the chain
for an instant. The result is an extremely fast, reverse reaction
which kicks the guide bar up and back toward the operator
(Fig. 20-21).
•Pinch-Kickback can occur when the wood closes in and
pinches the moving saw chain in the cut along the top of the
guide bar and the saw chain is suddenly stopped. This sudden
stopping of the chain results in a reversal of the chain force
used to cut wood and causes the saw to move in the opposite
direction of the chain rotation. The saw is driven straight back
toward the operator.
•Pull-In can occur when the moving chain contacts a foreign
object in the wood in the cut along the bottom of the guide bar
and the saw chain is suddenly stopped. This sudden stopping
pulls the saw forward and away from the operator and could
easily cause the operator to lose control of the saw.
Avoid Pinch-Kickback:
• Be extremely aware of situations or obstructions that can cause
material to pinch the top of or otherwise stop the chain.
• Do not cut more than one log at a time.

• Always begin cutting with the engine at full speed and the saw
housing against wood.
• Use wedges made of plastic or wood. Never use metal to hold
the cut open.
Reduce the Risk of Kickback
Recognize that kickback can happen. With a basic
understanding of kickback, you can reduce the
element of surprise which contributes to accidents.
• Never let the moving chain contact any object at the tip of the
guide bar.
• Keep the working area free from obstructions such as other
trees, branches, rocks, fences, stumps, etc. Eliminate or avoid
any obstruction that your saw chain could hit while you are cut-
ting through a particular log or branch.
• Keep your saw chain sharp and properly tensioned. A loose or
dull chain can increase the chance of kickback occurring.
Follow manufacturer’s chain sharpening and maintenance
instructions. Check tension at regular intervals with the engine
stopped, never with the engine running. Make sure the chain
brake nuts are securely tightened after tensioning the chain.
• Begin and continue cutting at full speed. If the chain is moving
at a slower speed, there is greater chance of kickback
occurring.
• Cut one log at a time.
• Use extreme caution when re-entering a previous cut.
• Do not attempt cuts starting with the tip of the bar (plunge cuts).
• Watch for shifting logs or other forces that could close a cut and
pinch or fall into chain.
• Use the Reduced-Kickback Guide Bar and Low-Kickback Chain
specified for your saw.
Maintain Control (Fig. 22-23)
• Keep a good, firm grip on the saw with both hands when the
engine is running and don’t let go. A firm grip will help you redu-
ce kickback and maintain control of the saw. Keep the fingers of
your left hand encircling and your left thumb under the front
handlebar. Keep your right hand completely around the rear
handle whether you are right handed or left handed. Keep your
left arm straight with the elbow locked.
• Position your left hand on the front handlebar so it is in a straight
line with your right hand on the rear handle when making
bucking cuts. Never reverse right and left hand positions for any
type of cutting.
• Stand with your weight evenly balanced on both feet.
• Stand slightly to the left side of the saw to keep your body from
being in a direct line with the cutting chain.
• Do not overreach. You could be drawn or thrown off balance
and lose control of the saw.

SAFETY RULES
• Do not cut above shoulder height. It is difficult to maintain con-
trol of saw above shoulder height.
Kickback Safety Features
WARNING: The following features are included on
your saw to help reduce the hazard of kickback;
however, such features will not totally eliminate this
dangerous reaction. As a chain saw user, do not rely
only on safety devices. You must follow all safety
precautions, instructions, and maintenance in this
manual to help avoid kickback and other forces
which can result in serious injury.
• Reduced-Kickback Guide Bar, designed with a small radius tip
which reduces the size of the kickback danger zone on the bar
tip. A Reduced-Kickback Guide Bar has been demonstrated to
significantly reduce the number and seriousness of kick-backs
when tested in accordance with safety requirements for gasoli-
ne powered chain saws as set by ANSI B175.1 - 2000.
• Low-Kickback Chain, designed with a contoured depth gauge
and guard link that deflect kickback force and allow wood to
gradually ride into the cutter. Low-Kickback Chain has met kick-
back performance requirements when tested on a representa-
tive sample of chain saws below 3.8 cubic inch displacement
specified in ANSI B175.1 - 2000.
• Front Hand Guard, designed to reduce the chance of your hand
contacting the chain as your hand slips off the front handlebar.
Chain Brake
Chain brakes are designed to rapidly stop the chain from rotating.
When the chain brake lever / hand guard is pushed toward the
bar, the chain should stop immediately. A chain brake does not
prevent kickback.
The chain brake Run Position (A) and Brake Position (B) are
illustrated on Fig. 24.
Chain brake should be cleaned and tested daily. Clean the chain
brake per the Maintenance-Chain Brake Section and test per the
Operation-Chain Brake Operation Section.
WARNING: Even with proper maintenance, the cor-
rect operation at the chain brake under field condi-
tions can not be certified.

WARNING: WE DO NOT REPRESENT AND YOU SHOULD NOT ASSUME THAT THE CHAIN
BRAKE WILL PROTECT YOU IN THE EVENT OF A KICKBACK. DO NOT RELY UPON ANY OF
THE DEVICES BUILT INTO YOUR SAW. YOU SHOULD USE THE SAW PROPERLY AND
CAREFULLY TO AVOID KICKBACK.
Reduced-Kickback Guide Bar and Low-Kickback Chain
Reduced-kickback guide bars and low-kickback saw chains reduce the chance and magnitude of kickback
and are recommended. Your saw has a low kickback chain and bar as original equipment. Repairs on a
chain brake should be made by an authorized servicing dealer. Take your unit to the place of
purchase if purchased from a servicing dealer, or to the nearest authorized service dealer.
WARNING: Computed kickback angle (CKA) listed on your saw and listed in the CKA table
below represents angle of kickback your bar and chain combinations will have when tested
in accordance with CSA (Canadian Standards Association) and ANSI standards. When
purchasing replacement bar and chain, considerations should be given to the lower CKA
values. Lower CKA values represent safer angles to the user, higher values indicate more
angle and higher kick energies. Computed angles represented indicate total energy and
angle associated without activation of the chain brake during kickback. Activated angle
represents chain stopping time relative to activation angle of chain break and resulting kick
angle of saw. In all cases lower CKA values represent a safer operating environment for the
user. The following guide bar and chain combinations meet kickback requirements of CSA
Standards Z62.1, Z62.3, & ANSI B175.1 when used on saws listed in this manual. Use of bar
and chain combinations other than those listed is not recommended and may not meet the
CKA requirements per standard.
WARNING: Do not mount a bow guide on any Efco chainsaw. The risk of kickback is
increased with a bow guide because of the increased kickback contact area.

SAFETY RULES
WARNING: The computer derived angles of par. 5.11 of ANSI B 175.1 – 2000 may bear no
relationship to actual kickback bar rotation angles that may occur in real life cutting situa-
tions.
In addition, features designed to reduce kickback injuries may lose some of their effective-
ness when they are no longer in their original condition, especially if they have been impro-
perly maintained.
Compliance with par. 5.11 of ANSI B 175.1 – 2000 does not automatically mean that in a real
life kickback the bar and chain will rotate at most 45°.
Precautions to Reduce Vibration Risk
• The chain saw is provided with anti-vibration (AV) system; never alter or modify it.
• Wear gloves and keep your hands warm.
• Keep the saw chain sharp and the saw, including the AV system, well maintained. A dull chain will increase
cutting time, and pressing a dull chain through wood will increase the vibrations transmitted to your
hands.
• Maintain a firm grip at all times, but do not squeeze the handles with constant, excessive pressures, take
frequent breaks. All the above mentioned precautions do not guarantee that you will not sustain white-
finger disease or carpal tunnel syndrome. Therefore, continual and regular users should monitor closely
the condition of their hands and fingers. If any of the above symptoms appear, seek medical advice
immediately.
Maintenance Precaution
WARNING: Never operate a chain saw that is damaged, improperly adjusted, or is not com-
pletely 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 carburetor may need adjusting, see Operation-Carburetor Adjusting Section.
If the saw chain still moves at idle speed after adjustment has been made, contact a Servicing Dealer for
adjustment and discontinue use until the repair is made.
WARNING: All chain saw service, other than items in the Operator's Manual maintenance
instructions, have to be performed by competent chain saw service personnel. (If improper
tools are used to remove the flywheel or clutch, 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 burst and serious injury could result.)
• Never modify your saw in any way.
• Keep the handles dry, clean, and free of oil or fuel mixture.
WARNING: Use only accessories and replacement parts recommended.

performing maintenance to the chain.
1 Ensure that the chain brake is not set by pulling the chain brake
lever / hand guard towards the front handle as shown in Fig. 25.
Refer to Safety-Chain Brake and Operation-Chain Brake
Sections for additional information.
2. Remove the bar nut (A, Fig. 26) and the clutch cover (B).
3. Remove and discard the plastic shipping spacer (C, Fig.
27) that has been installed on the bar studs in place of the
bar for shipping purposes.
4. Adjust the chain tensioning pin (D) fully towards the brake band
by turning the chain tensioning screw (E) counterclockwise as
shown in inset (Fig. 27).
5. The guide bar (F) contains a bar stud slot that fits over the bar
studs (G). The guide bar also contains two chain tensioning pin
holes (H) and two lubrication holes, one per side. The bar is
reversible and either tensioning pin hole may be utilized with
the chain tensioning pin.
6. Place the guide bar (F) onto the bar studs (G) as shown in Fig.
27.
7. Position the guide bar (F) tip through the chain (H) loop as
shown in Fig. 28. The cutters on the top of the guide bar should
face toward the bar nose, in the direction of the chain rotation.
See insert (M) in (Fig. 29).
8. Fit the chain (H) over the rim sprocket (I) and into bar groove.
CAUTION: Severe damage can occur to the rim
sprocket, clutch drum, guide bar and chain, if the
chain is not correctly seated into the rim sprocket.
9. Replace the clutch cover (B). Turn the chain tensioning screw
(E) clockwise (as shown in Fig. 30) until the chain tensioning
pin (D) fits into the chain tensioning pin hole (H). Install the bar
nut (A). Tighten the bar nut finger tight only. The bar must be
free to move for tension adjustment.
CAUTION: Failure to ensure that the chain tensioning
pin is in the chain tensioning pin hole will result in
severe damage to the chain saw during reassembly
of the clutch cover.
NOTE: If the clutch cover does not slide on freely, check that
the chain brake is not engaged. To disengage chain brake
with clutch cover removed, grasp clutch cover as shown in
Fig. 25 and pull back on chain brake lever / hand guard.
10. Remove all slack from chain by turning the chain tensioning
screw (E) clockwise, assuring that the chain seats into the bar
groove during tensioning.
11. Lift the tip of the guide bar up to check for sag, see Fig. 31.
Release the tip of the guide bar, and turn the chain tensioning
screw (E) 1/2 turn clockwise. Repeat this process until sag

OPERATION
Chain Tension
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
to the chain.
1. Stop the engine before setting the chain tension. Loosen
the guide bar nuts slightly, turn the chain tensioning screw
clockwise to tension the chain. Refer to Assembly-Assembling
the Bar and Chain Section. Retighten guide bar nuts. A cold
chain is correctly tensioned when there is no slack on the
underside of the guide bar, the chain is snug, but it can be
turned by hand without binding.
For warm chain, see Item 3.
2. Chain must be retensioned whenever the flats (A) on the drive
link tangs hang out of the bar groove. See Fig. 34.
3. During normal saw operation, the temperature of the chain will
increase. The drive link tangs of a correctly tensioned warm
chain will hang approximately .050” (1.25 mm) out of the bar
groove. See Fig. 35. To help determine the correct warm chain
tension, the tip of the combination wrench (Fig. 36) can be
used as a guide.
CAUTION: Chain tensioned while warm, may be too
tight upon cooling. Check the "cold tension" before
next use.
CAUTION: A new chain has to be retensioned more
often than one that has been in use for some time.
Breaking-in the Chain
New chains will stretch and must be tightened frequently.
Lift the chain out of the bar groove and lubricate the bar groove
with additional oil, see Fig. 37. Place the chain saw on a piece of
cardboard or scrap plywood. Start the chain saw (refer to the
Operation-Starting Engine Section) and allow it to run at moderate
speed for approximately one (1) minute. Stop the engine. Check
that the oil pump is working properly. The cardboard should have
excess oil from the chain rotation if the oil pump is working pro-
perly, see Fig. 38. Adjust the chain tension (refer to Operation-
Chain Tension Section). Start the saw again and make a few cuts
in a log to heat up the chain. Stop the engine and re-adjust chain
again. Repeat this process until the chain retains proper warm
tension adjustment as shown in Fig. 35 in Operation-Chain
Tensioning Section. Never touch the ground with the chain.
