SAFETY INSTRUCTIONS FOR CHAIN SAW
Keep all parts of the body away from the saw chain when the chain saw
is operating. Before you start the chain saw, make sure that the saw chain is not contacting anything. A moment of inattention while operating chain saws may cause entanglement of your clothing or body with the chain.
Always hold the chain saw with your right hand on the rear handle and
your left hand on the front handle. Holding the chain saw with a reversed hand configuration increases the risk of personal injury and should never be done.

56V LITHIUM-ION CORDLESS CHAIN SAW — CS1800/CS1800-FC

9

Hold the chain saw by insulated gripping surfaces only, because the saw
chain may contact hidden wiring. Saw chains contacting a “live” wire may make exposed metal parts of the chain saw”live” and could give the operator an
electric shock.
Wear eye protection. Further protective equipment for hearing, head,
hands, legs and feet is recommended. Adequate protective equipment will reduce personal injury from flying debris or accidental contact with the saw
chain.
Do not operate a chain saw in a tree, on a ladder, from a rooftop, or
any unstable support. Operation of a chain saw in this manner could result in serious personal injury.
Always keep proper footing and operate the chain saw only when
standing on fixed, secure and level surface. Slippery or unstable surfaces may cause a loss of balance or control of the chain saw.
When cutting a limb that is under tension be alert for spring back. When
the tension in the wood fibers is released the spring loaded limb may strike the
operator and/or throw the chain saw out of control.
Use extreme caution when cutting brush and saplings. The slender
material may catch the saw chain and be whipped toward you or pull you off
balance.
Carry the chain saw by the front handle with the chain saw switched off
and away from your body. When transporting or storing the chain saw, always fit the guide bar cover. Proper handling of the chain saw will reduce the likelihood of accidental contact with the moving saw chain.
Follow instructions for lubricating, chain tensioning and changing the
bar and chain. Improperly tensioned or lubricated chain may either break or increase the chance for kickback.
Cut wood only. Do not use chain saw for purposes not intended. For
example: do not use chain saw for cutting metal, plastic, masonry or non-wood building materials. Use of the chain saw for operations different than intended could result in a hazardous situation.
Do not attempt to fell a tree until you have an understanding of the
risks and how to avoid them. Serious injury could occur to the operator or bystanders while felling a tree.

56V LITHIUM-ION CORDLESS CHAIN SAW — CS1800/CS1800-FC

CAUSES AND OPERATOR PREVENTION OF KICKBACK
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 sudden reverse reaction, kicking the guide bar up and back towards the operator.
Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back towards the operator.
Either of these reactions may cause you to lose control of the saw, which could result in serious personal injury. Do not rely exclusively 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.
Kickback is the result of chain saw misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below:
Maintain a firm grip, with thumbs and fingers encircling the chain saw
handles, with both hands on the saw and position your body and arm to allow you to resist kickback forces. Kickback forces can be controlled by the operator, if proper precautions are taken. Do not let go of the chain saw.
Do not overreach and do not cut above shoulder height. This helps prevent
unintended tip contact and enables better control of the chain saw in unexpected situations.
Only use replacement guide bars and saw chains specified by the
manufacturer. Incorrect replacement guide bars and saw chains may cause chain breakage and/or kickback.
Follow the manufacturer’s sharpening and maintenance instructions
for the saw chain. Decreasing the depth gauge height can lead to increased kickback.

56V LITHIUM-ION CORDLESS CHAIN SAW — CS1800/CS1800-FC

KICKBACK SAFETY DEVICES ON THIS CHAIN SAW

Chain Brake
The chain saw comes equipped with a chain brake, which stops both the motor and the motion of the chain when kickback occurs. The chain brake can be activated by the forward motion of the chain-kickback brake handle as the saw rotates backward during kickback; it can also be activated by the inertial forces generated during rapid pushback.

WARNING: Never modify or attempt to disable the chain brake.

Make sure that the chain brake is working properly before using the chain saw. The chain-kickback brake handle should move back and forth easily.

To test the operation of the chain brake, perform the following steps (Fig. 1):

1

Place the chain saw on a flat bare

surface and make sure no objects

or obstructions that could come in

Chain kickback brake handle in operationg position
Chain kickback brake handle in brake position

contact with the bar and chain are in

the immediate vicinity.
Disengage the chain brake by

pulling the chain-kickback brake

handle towards the front handle.
Start the chain saw. Push the chain-kickback brake handle towards the front of the saw. A properly

functioning hand brake will stop the movement of the chain immediately. If the

chain brake is not working properly, do not use the chain saw until it has been

repaired by a qualified service technician.

WARNING: Confirm that the chain brake works properly before each use.

WARNING: If the chain brake is clogged with wood chips, the function of the
chain brake may deteriorate. Always keep the device clean.

12

56V LITHIUM-ION CORDLESS CHAIN SAW — CS1800/CS1800-FC

Low Kickback Saw Chain

The ramp-shaped depth gauges ahead of each cutter can minimize the force of a kickback reaction by preventing the cutters from digging in too deeply at the kickback zone. Only use a replacement chain that is equivalent to the original chain or has been certified as a low kickback chain per ANSI B175.1. A low kickback tooth saw chain is a chain that has met the kickback performance requirements of ANSI B175.1 (American National Standard for Power Tools- Gasoline-Powered Chain Saws-Safety Requirements) when tested on the representative sample of chain saws below 3.8 c.i.d. specified in ANSI B175.1.

The bumper drive link (Fig. 2) also helps deliver low-kickback performance.

2

CAUTION: As saw chains are
sharpened during their useful life, they lose some of the low kickback qualities and extra caution should be used.
GUIDE BAR

Bumper drive link

Cutter type

This saw comes equipped with a guide bar that has a small radius nose. Small radius noses generally have less potential for kickback. When replacing the guide bar, be sure to order the bar listed in this manual.

56V LITHIUM-ION CORDLESS CHAIN SAW — CS1800/CS1800-FC

13

ADDITIONAL WARNINGS

With a basic understanding of
kickback (Fig. 3-5), you can

3

reduce or eliminate the element

of surprise. Sudden surprise

contributes to accidents.
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.

4

Inspect the work piece for nails,

wire, or other foreign objects

prior to cutting.
Plan the work, ensuring an

obstacle-free work area and, in

the case of felling, at least one

escape path from the falling

tree.

When felling, keep bystanders

5

at least two tree lengths away.
Keep proper footing and balance

at all times.

switch trigger and maintain cutting

speed.
Push and Pull The reaction force

is always opposite to the direction 7
the chain is moving where wood

contact is made. Thus, 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 (Fig. 7).

Avoid unintentional contact

Pull

with the stationary saw chain or

guide bar rails. These can be very

sharp. Always wear gloves and long

pants or chaps when handling the

chain saw, saw chain, or guide bar.

Never operate a chain saw

that is damaged or improperly

adjusted or that is not

completely and securely

assembled. Be sure that the saw

chain stops moving when the trigger

Push

switch is released.

When bucking, secure the work piece prior to cutting. When felling or

pruning, identify and secure hazardous branches.
Aggressive or abusive cutting or misuse of the chain saw can cause

premature bar, chain, and/or sprocket wear, as well as a broken chain or

bar, leading to kickback, chain throw or the ejection of material.

56V LITHIUM-ION CORDLESS CHAIN SAW — CS1800/CS1800-FC

1. Remove the battery pack from the chain saw.
2. Clean the oil-tank cap and the area around it to ensure that no dirt falls into the oil tank.
3. Position the chain saw on its side on a firm, flat surface, so that the oil-tank cap is facing upwards. Rotate the oil-tank cap counterclockwise to remove it (Fig. 9).
4. Carefully pour the bar and chain oil into the oil tank. Be careful not to let the oil spill from the opening. Fill to the bottom of the fill neck. Wipe off any excess oil.
5. Replace the cap, place the saw upright, and view the level through the oilinspection window. Oil should fill the window.
NOTICE:
Use OREGON® bar and chain oil for best results. It is specially designed to provide
low friction and faster cuts.
Never use oil or other lubricants not specifically designed for use on the bar and
chain. This can lead to a clogged oil system, which may cause premature wear of the bar and chain.
Check the oil level frequently and fill when the oil level falls below the minimum
mark. Never operate the chain saw if the oil is not visible.
Do not use dirty, used, or otherwise contaminated oil. Damage may occur to the
bar or chain.
It is normal for oil to seep from the saw when it is not in use. To prevent seepage,
empty the oil tank after each use, and then run the saw for one minute. When storing the tool for a long period of time, be sure the chain is lightly lubricated; this will prevent rust on the chain and bar as well as the inside drive sprocket.
To preserve natural resources, please recycle or dispose of oil properly. Consult
your local waste authority for information regarding available recycling and disposal options.

PREPARATION FOR CUTTING

Refer to section”SAFETY INSTRUCTIONS” earlier in this manual for appropriate safety equipment.

Work Area Precautions
Cut only wood or materials made from wood; do not cut sheet metal, plastics,
masonry, or non-wood building materials.
Never allow children to operate the chain saw. Allow no person to use this chain saw who has not read this Operator’s Manual or
received adequate instructions for the safe and proper use of this chain saw.
When felling a tree, keep everyone – helpers, bystanders, children, and animals – a
safe distance away from the cutting area. During felling operations, the safe distance should be a least twice the height of the largest trees in the felling area. During bucking operations, keep a minimum distance of 15 feet (4.5 m) between workers. Trees should not be felled in a manner that would endanger any person, strike a utility line, or cause any property damage. If a tree does make contact with a utility line, stay clear of the tree and the line and notify the utility company immediately.
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. Cut only when visibility and light are adequate for you to see clearly.

Proper Grip On Handles

Wear non-slip gloves for maximum

grip and protection.

14

With the saw on a firm, flat surface,

hold the saw firmly with both hands.

Always grasp the front handle with

the left hand and the rear handle

with the right hand.

The fingers should encircle the

handle, with the thumb wrapped

under the front handle (Fig. 14).

Grip with thumb below handle
BRUSHLESS

28

56V LITHIUM-ION CORDLESS CHAIN SAW — CS1800/CS1800-FC

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

WARNING: Do not operate the
trigger switch with your left hand and

15

hold the front handle with your right hand.

Never allow any part of your body to be in

the chain line while operating a chain saw

(Fig. 15).

Proper Cutting Stance (Fig. 16)
Both feet should be on solid ground,
with weight evenly spread between them.
The left arm should be straight,
with the elbow locked. This helps to withstand the forces generated by kickback.
Your body should always be to the
left of the chain line.

CUTTING
Basic Cutting WARNING: Always be sure of your footing and hold the chain saw firmly with
both hands while the motor is running. Practice cutting a few small logs using the following technique to get the “feel” of using your saw before you begin a major sawing operation.
1. Take the proper stance in front of the wood with the saw off. 2. Press the lock-off button and squeeze the variable-speed trigger switch to start
the chain saw. Let the chain reach the full selected speed before beginning the cut. 3. Begin cutting by lightly pressing the guide bar against the wood. Use only light pressure, letting the saw do the work. 4. Maintain a steady speed throughout the cut, releasing pressure just before the end of the cut. 5. Release the trigger switch as soon as the cut is completed, allowing the chain to stop.
WARNING: When the saw chain is stopped due to pinching during cutting,
release the trigger switch; remove the saw chain and guide bar from the wood, then restart the chain saw.
WARNING: Do not pull the saw chain with your hand when it is bound by the
sawdust. Serious injury could result if the chain saw starts accidentally. Press the saw chain against the wood, move the chain saw back and forth to discharge the debris. Always remove the battery pack before cleaning. Wear heavy protective gloves when handling the saw chain.
WARNING: Never start the chain saw when it is in contact with the wood.
Always allow the chain saw reach full speed before applying the saw to the wood.

FELLING A TREE
Hazardous Conditions
WARNING: When felling a tree, it is important that you heed the following
warnings to prevent possibly serious injury.
Do not fell trees during periods of high wind or heavy precipitation. Wait until the
hazardous weather has ended.
Do not fell trees that lean at extreme angles or large trees with rotten limbs, loose
bark, or hollow trunks. Instead, have these trees pushed or dragged down with heavy equipment and then cut them up.
Do not fell 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 assure 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!
Preparation for Tree Felling
When bucking and felling operations are being performed by two or more persons
at the same time, the felling operation should be separated from the bucking operation by a distance of at least twice the height of the tree being felled. Trees should not be felled in a manner that would endanger any person, strike any utility line or cause any property damage. If a tree does make contact with a utility line, stay clear of the tree and the line and notify the utility company immediately.
The chain saw operator should stand on the uphill side of the terrain, as the tree
is likely to roll or slide downhill after it is felled.

56V LITHIUM-ION CORDLESS CHAIN SAW — CS1800/CS1800-FC

31

Before any cuts are started, pick
your escape route (or routes, in

17

Felling Direction

case the intended route is blocked).

Clear the immediate area around

Dangerous Zone

the tree and make sure that there

are no obstructions in your planned paths of retreat. Clear a path of safe

Safety Retreat Path

retreat approximately 135° from the

45°

planned line of fall. The retreat path should extend back and diagonally

Dangerous Zone

to the rear of the expected line of

fall. See Fig. 17.
Before felling is started, consider the natural lean of the tree, the location of larger

branches and the wind direction to judge which way the tree will fall.
Remove dirt, stones, loose bark, nails, staples, and wire from the tree where

felling cuts are to be made.

Notching undercut
Make the notch 1/3 the diameter of the tree, perpendicular to the direction of fall, as illustrated in Fig. 18. Make the lower horizontal notching cut first. This will help to avoid pinching of either the saw chain or the guide bar when the second notch is being made.

18
Direction of fall Notch

Notching Undercut

2 in. (50.8 mm)

Felling back cut
2 in. (50.8 mm)
Hinge

Felling Back Cut

1. Make the felling back cut at least 2 inches (50.8 mm) higher than the horizontal notching cut (see Fig. 18). Keep the felling back cut parallel to the horizontal notching cut. Make the felling back cut so that enough wood is left to act as a hinge. The hinge wood keeps the tree from twisting and falling in the wrong direction. Do not cut through the hinge.

2. As the felling cut gets close to the hinge, the tree should begin to fall. If there is any chance that the tree may not fall in the desired direction or it may rock back and bind the saw chain, stop cutting before the felling back cut is complete and use wedges of wood, plastic or aluminum to open the cut and drop the tree along the desired line of fall.

32

56V LITHIUM-ION CORDLESS CHAIN SAW — CS1800/CS1800-FC

3. When the tree begins to fall, remove the chain saw from the cut, stop the motor, put the chain saw down, then use the retreat path planned. Be alert for overhead limbs falling and watch your footing.

LIMBING
Limbing is removing branches from a fallen tree. When limbing, leave larger limbs to support the log off the ground. Remove the small limbs in one cut as illustrated in Fig. 19. Branches under tension should be cut from the bottom up to avoid binding the chain saw.

19
Limb Cut

Tree Limbing

WARNING: There is an extreme
danger of kickback during the limbing operation. Be extremely cautious and avoid
contacting the log or other limbs with the tip of the guide bar.

BUCKING A LOG (Fig. 20)
Bucking is cutting a log into lengths. It is important to make sure your footing is firm and your weight is evenly distributed on both feet. When possible, the log should be raised and supported by the use of limbs, logs, or chocks. Follow the simple directions for easy cutting.
WARNING: Keep a clear-cutting
area. Make sure that no objects can contact the guide bar nose and chain during cutting; this can cause kickback.

Overbucking

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

33 56V LITHIUM-ION CORDLESS CHAIN SAW — CS1800/CS1800-FC

Underbucking
Begin on the underside of the log with the top of the saw against the log; exert light pressure upward. During underbucking, the saw will tend to push back at you. Be prepared for this reaction and hold the saw firmly to maintain control.
When the log is supported along its
entire length, it should be cut from the top (overbucking) (Fig. 21).
When the log is supported on only
one end, cut 1/3 the diameter from the underside (underbucking). Then make the finishing cut by overbucking to meet the first cut (Fig. 22).
When the log is supported on both
ends, cut 1/3 of that diameter from the top overbuck. Then make the finished cut by underbucking the lower 2/3 to meet the first cut (Fig. 23).

MAINTENANCE

WARNING: To avoid serious personal injury, remove the battery pack from the
chain saw before inspecting, cleaning, or performing maintenance. A battery- operated tool with the battery pack inserted is always on and can start accidently.
WARNING: When servicing, use only identical replacement parts. Use of any
other parts may create a hazard or cause product damage.
WARNING: Always wear heavy gloves when doing any maintenance on the saw
chain. Be careful of the saw chain and protect your hands from being injured by the saw chain.
WARNING: When cleaning the chain saw, DO NOT immerse it in water or other
liquids.
WARNING: Do not at any time let brake fluids, gasoline, petroleum-based
products, penetrating oils, etc., come in contact with plastic parts. Chemicals can damage, weaken, or destroy plastic, which may result in serious personal injury. All chain saw service, other than the items listed in this manual, should be performed by a qualified service technician.
CLEANING
After each use, clean debris from the chain and guide bar with a soft brush. Wipe
the chain saw surface with a clean cloth moistened with a mild soap solution.
For deep clearing, remove the side cover, take down the guide bar and saw chain
and then use a soft brush to thoroughly remove debris from the guide bar, saw chain, and the drive sprocket on the chain saw power head.
Always clean out wood chips, saw dust, and dirt from the guide bar groove when
replacing the saw chain.
36 56V LITHIUM-ION CORDLESS CHAIN SAW — CS1800/CS1800-FC

REPLACING THE BAR AND CHAIN

and then rotate the chain by hand

to check whether the chain is properly assembled without binding. Otherwise,

reassemble the chain and bar.

CHAIN MAINTENANCE

Use only low-kickback chains on this saw. This fast cutting chain will provide kickback reduction when properly maintained.
A properly sharpened saw chain cuts through wood effortlessly, even with very little pressure. Never use a dull or damaged saw chain. A dull saw chain cutter leads to increased physical strain, increased vibration load, unsatisfactory cutting results, and increased wear.

39 56V LITHIUM-ION CORDLESS CHAIN SAW — CS1800/CS1800-FC

For smooth and fast cutting, the chain needs to be maintained 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 cuts to one side. During maintenance of your chain, consider the following:
Improper filing angle of the side plate can increase the risk of a severe kickback. Depth gauge clearance. Too low increases the potential for kickback. Not low enough
decreases cutting ability.
If cutter teeth have hit hard objects, such as nails and stones, or have been abraded by
mud or sand on the wood, have the chain sharpened by a qualified service technician.
NOTICE: 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 qualified service technician.

How to Sharpen the Cutters

Be careful to file all cutters (Fig. 31) to the specified angles and to the same length,

31

as fast cutting can be obtained only when

all cutters are uniform.

1. Remove the battery pack. Wear gloves for protection.

Top Plate

Side Plate
Depth Gauge

2. Make sure that the chain is properly mounted and the quick chain-tension adjust knob is fully tightened, which ensures that the chain is correctly tensioned.

3. Use a 5/32″ (4.0 mm) diameter round file and holder (available separately). Do all of your filing at the middle position of the guide bar for perfect balance.

4. Keep the file level with the top plate of the tooth. Do not let the file dip or rock.

40

56V LITHIUM-ION CORDLESS CHAIN SAW — CS1800/CS1800-FC

5. Keep a correct sharpening angle of 30° between the file and the saw chain; see Fig. 32 & 33. Always use a file holder (available separately) when sharpening saw chains by hand. File holders have markings for the sharpening angle.

32 5/32″ (4.0 mm)
Round File Filing Direction

6. Using light but firm pressure, stroke

towards the front corner of the

tooth. Lift the file away from the

steel on each return stroke.

7. Make a few firm strokes on every tooth. File all left-hand cutters in one direction. Then move to the other side and file the right-hand cutters in the opposite direction. Occasionally remove filings from the file with a wire brush (Fig. 34).

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

Use a depth-gauge tool (available

separately) to check the depth-

gauge clearances.

Depth Gauge Clearance 0.025″ (0.6 mm)

2. Check the depth-gauge clearance every time the chain is filed. Use a flat file and a depth-gauge jointer (both available separately) to lower all gauges uniformly (Fig. 38). Depth-gauge jointers are available from 0.020 in. to 0.035 in. (0.5 mm to 0.9 mm). Use a 0.025 in. (0.6 mm) depth-gauge jointer.

38 Depth Gauge Jointer

3. 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 the cutter face with the flat file

when adjusting depth-gauges.

GUIDE BAR MAINTENANCE
When the guide bar shows signs of wear, 39
disassemble it from the chain saw power head and reverse it for reassembly (Fig. 39), in which case it will distribute the wear for maximum bar life.

56V LITHIUM-ION CORDLESS CHAIN SAW — CS1800/CS1800-FC

43

The bar should be cleaned (including bar rails and lubricating hole) every day of use

40

and checked for wear and damage

(Fig. 40). 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.

See the section” REPLACING THE BAR

AND CHAIN” in this manual.

Wear inside the bar rails which

permits the chain to lay over
