IMPORTANT SAFETY INSTRUCTIONS
WARNING: WHEN USING AN ELECTRIC CHAIN SAW, BASIC SAFETY PRECAUTIONS SHOULD ALWAYS BE FOLLOWED TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, AND INJURY TO PERSONS, INCLUDlNG THE FOLLOWING:
READ ALL INSTRUCTIONS (1)
-Keep Work Area Clean
Cluttered areas invite injuries. Do not start cutting until you have a clear work area, secure footing, and a planned retreat path from the falling tree.
-Consider Work Area Environment
Use extreme caution when cutting small size brush and saplings because the slender material may catch the saw chain and be whipped toward you or pull you off balance. Do not operate a chain saw in a tree unless specifically trained to do so. 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 fibers is released. Don't
expose chain saw to rain (3). Don’t use chain saw in damp or wet locations. Do not use chain saw in presence of flammable liquids or gases.
-Guard Against Electric Shock
Prevent body contact with grounded surfaces. For example: metal pipes, wire fences.
-Keep Children Away
Do not let visitors contact chain saw or extension cord. All visitors should be kept away from work area (4).
-Store Idle Chain Saw
When not in use, chain saws should be stored in a dry and high or locked up place-out of the reach of children.
When storing saw, use a scabbard or carrying case.
-Don’t Force Chain Saw
It will do the job better and safer at the rate for which it was intended.
-Use Right Tool
Cut wood only. Don’t use chain saw for purpose not intended - for example - Don’t use chain saw for cutting plastic, masonry nonwood building materials.
-Dress Properly
Do not wear loose clothing or jewelry. They can get caught in moving parts. Rubber gloves and non-skid footwear are recommended when working outdoors.
Wear protective hair covering to contain long hair.
-Use Safety Glasses
Also use safety footwear; snug fitting clothing; protective gloves; hearing and head protection (5).
-Carrying Saw
Carry the chain saw by the front handle with the saw stopped, finger off the switch, the guide bar and saw chain, covered with the chain protection, to the rear.
-Maintain Chain Saw With Care
Inspect chain saw cords periodically and if damaged, have repaired by authorized service facility. Keep cord clear of the chain and operator at all times. Never carry

saw by the cord or pull it to disconnect from receptacle. Keep cord from oil and sharp edges. Inspect extension cords periodically and replace if damaged. Keep tools sharp and clean for better and safer performance. Follow instructions for lubricating and changing accessories. Keep handles dry, clean, and free from oil and grease.
-Disconnect Chain Saw
Disconnect chain saw when not in use, before servicing, and when changing accessories and attachments, such as saw chain and guard (6).
-Outdoor Use Extension Cords
Use only extension cords intended for use outdoors and so markerd.
-Stay Alert
Watch what you are doing. Use common sense. Do not operate chain saw when you are tired. Keep all parts of the body away from the saw chain when the motor is operating. Before you start the saw, make sure the saw chain is not contacting anything.
-Check Damaged Parts
Before further use of the chain saw, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting, and any other conditions that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced by an authorized service center unless otherwise indicated elsewhere in this instruction manual. Have defective switches be replaced by authorized service center. Do not use chain saw if the switch does not turn the saw on and off. Do not operate a chain saw that is damaged, improperly adjusted, or is not completely and securely assembled (7). Be sure that the saw chain stops moving when the trigger is released.
-Guard Against Kickback
WARNlNG: KICKBACK may occur when the nose or tip of the guide bar touches an object (8), 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 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 injury to user. The following precautions should be followed to minimize kickback:
-Grip saw firmly. Hold the chain saw firmly with both hands when the motor is running (9). Use a firm grip with thumbs and fingers encircling the chain saw handles.
-Do not over reach.
-Keep proper footing and balance at all times.
-Don’t let the nose of the guide bar contact a log, branch, ground, or other obstruction.
-Don’t cut above shoulder height (10).
-Use devices such as low kickback chain, chain brakes and special guide bars that reduce the risks associated with kickback.
-Only use replacement bars and chains specified by the rnanufacturer.

-Power Supply
Connect chain saw to correct voltage, that is, be sure that the voltage supplied is the same as that specified on the nameplate of the tool (11).
-Replacement Parts
When servicing, use only identical replacement parts (11).
-Polarized Plugs
To reduce the risk of electric shock, this equipment has a polarized plug (one blade is wider than the other). This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install the proper outlet. Do not change the plug in any way.
-Wear ear protectors during operation.
-Before making a felling cut, remove dirt, stones, loose bark, nails, staples and wire from the tree.
-Secure the log so that it will not rol or move suddenly during operation.
-AVOlD UNINTENTIONAL STARTING. Don’t carry plugged-in tool with finger on switch. Be sure switch is OFF when plugging in.
-Attention! Do not expose this tool to rain (12) and pull plug immediately if the supply cable is damaged or cut (13).
-The chain saw must not be left outdoors during rain and it must not be used when wet.
VOLTAGE WARNING:
Before connecting the tool to a power source (receptacle outlet, etc.) be sure the voltage supplied is the same as that specified on the nameplate of the tool. A power source with voltage greater than that specified for the tool can result in SERIOUS INJURY to the user - as well as damage to the tool. If in doubt, DO NOT PLUG IN THE TOOL. Using a power source with voltage less than the nameplate rating is harmful to the motor.
Use of Extension Cord
If the extension cord is intended to be used outdoors, the cord shall be marked with the suffix W-A following the cord type designation, for example - SJTW-A, to indicate it is acceptable for outdoor use. Use an extension cord heavy enough to carry the current the tool will draw. Undersize cord will cause a drop in line voltage resulting in loss of power and over-heating. Make sure the extension cord is in good condition before using. Keep the cord away from the cutting area and to position cord so that it will not be caught on branches, and the like, during cutting. Use the table below to determine the proper wire size required in the extension cord.
Contact DOLMAR Authorized or Factory Service Center if a proper extension cord cannot be found.

E |
-When putting on the sprocket guard (E/1) make sure that the sprocket guard lug (E/10) fits into the hole (see enlarged illustration).
-Tighten mounting nut (E/2) lightly by hand.
CAUTION: When working on the guide bar or saw chain always wear protective gloves and pull out the power supply plug.
CAUTION: Switch on the electric chain saw only after having assembled it completely and inspected!
7 |
5 |
6 |
B |
|
|
-Lay the chain (B/5) on the guide bar (B/6).
-The cutting edges (B/7) of the chain on the top edge of the guide bar must face in the direction shown by the arrow.
D |
-Position the guide bar. Take care that the pivot (A/4) of the chain tightener is inserted into the bore (see circle) of the guide bar.
F
Tightening the saw chain
-Slightly lift the end of the guide bar and turn the chain tightener screw (A/3) to the right (clockwise) until the saw chain rests against the bottom side of the guide bar (see circle).
-Continue to lift the guide bar end and firmly tighten the fastening nut (E/2) by means of the universal wrench.
8
Checking the chain tension
The chain has the proper tension when it lies against the bottom edge of the guide bar and can be easily pulled by hand about 5 mm (a little under 1/4") up from the guide bar.
Check the chain tension frequently - new chains tend to get longer during use!
When checking the chain tension the motor must be switched off and the power supply plug pulled out.
HINT:
Use 2 or 3 saw chains alternately for even wear of the chains, sprocket and guide bar running surfaces.
In order to guarantee a uniform wear of the groove in the bar the bar should be turned over whenever replacing the chain.
Chain brake
H
The ES-151, ES-161 and ES-171 comes with an inertia chain brake as standard equipment. If kickback occurs due to contact of the guide-bar tip with wood (see SAFETY PRECAUTIONS, page 5), the chain brake will stop the chain through inertia if the kickback is sufficiently strong.
The chain will stop within a fraction of a second.
G |
2 |
1 |
|
11 |
I |
|
Engaging the chain brake (braking)
If the kickback is strong enough the sudden acceleration of the guide bar combined with the inertia of the hand guard (I/11) will automatically actuate the chain brake.
To engage the chain brake manually, simply push the hand guard (I/11) forward (towards the tip of the saw) with your left hand (arrow 1).
Releasing the chain brake
Pull the hand guard (I/11) towards you (arrow 2) until you feel it catch. The brake is now released.
Note:
When the chain brake is actuated the power supply to the motor will be cut off. Testing of the chain brake is described on page 12.
Chain brake maintenance
SERVICE
The chain brake is a very important safety feature, and like any other part it is subject to a certain amount of wear. Regular inspection and maintenance is important for your personal safety, and can be properly performed only by a DOLMAR service center.
9
Saw chain oil
A
Use a special oil with adhesive addition for lubricating the saw chain and bar. The adhesive addition prevents that the oil is centrifuged too fast from the sawing device.
Do not use mineral oils. In order to protect the invironment the use of biologically decomposeable oil is prescribed.
The saw chain oil sold by DOLMAR, called BIOTOP, is made of special vegetable oils and is biologically decomposeable to 100%. BIOTOP has been granted the "blue angel" for being particularly favourable to the environment (RAL UZ 48).
Biologically decomposeable oil is stable only for a limited period of time. It should be consumed within 2 years from the date of manufacture (printed on the container).
BIOTOP oil is available in the following packing sizes to suit your individual requirements:
1 liter |

Waste oil
B
Never use waste oil
Waste oil is very dangerous for the environment.
Waste oil contains high amounts of carcinogenic substances.
The residues in the waste oil result in a high degree of wear and tear at the oil pump and the sawing device.
In the case of damage caused by using waste oil or unappropriate saw chain oil the product guarantee will be null and void.
Your salesman will inform you about the use of saw chain oil.
Avoid skin and eye contacts
Mineral oil products as well as oil degrease the skin. If your skin repeatedly comes in contact with these substances for a longer period of time, it will desiccate. Various skin deseases may result. In addition, allergic reactions are known.
Eyes can be irritated by contact with oil. If oil gets into your eyes, immediately wash them with clear water. If your eyes are still irrritated, go to see a doctor.
Refilling the oil tank
1 |
C |
Only if the motor is switched off and the power supply plug is pulled out
-Thoroughly clean the oil tank around the cap to prevent dirt from entering the tank.
-Unscrew the tank cap (C/1) and fill in chain oil until it is on a level with the bottom edge of the filler socket.
-Tightly screw on the tank cap.
-Thoroughly remove any oil that has overflown.
Important!
Before operating the saw for the first time, the oil feed system must be completely filled, until the chain oil lubricates the chain and guide bar.
This procedure can take up to two minutes.
D2
-The oil level can be controlled in the sight glass (D/2).
Lubricating the saw chain
In order to ensure sufficient lubrication of the saw chain there must always be enough oil in the tank. Its contents (120 ml) is sufficient for approx. 1/2 hour at continuous operation.
Important note on bio-degradable chain oils:
If you are not planning to use the saw again for an extended period of time, empty the oil tank and put in a small amount of regular engine oil (SAE 30),and then run the saw for a time. This is necessary to flush out all remaining bio-degradable oil from the oil tank, oil-feed system, chain and guide bar, as many such oils tend to leave sticky residues over time, which can cause damage to the oil pump or other parts.
The next time you use the saw, fill the tank with BIOTOP chain oil again.
The next time you use the saw refill the tank with new BIOTOP chain oil.

Switching on the motor
5
6
F
-Plug in the saw.
-When switching on the electric chain saw always hold it with both hands.
-Take the back handle with the right hand and the tubular handle with the left hand. Hold the handles tightly with your thumbs facing your fingers. The bar and chain must not be in contact with any object.
-First depress the locking button (F/5) and then the power switch (F/6). Then release the locking button (F/5).
-Attention: The chain starts running immediately. Keep the power switch depressed as long as the motor is to run.
CAUTION:
Never lock the power switch in the ON position.
Switching off the motor:
-Release the power switch (F/6).
Holding the chain saw
Use this grip thumb
below handle!
H
Always grip each handle with the thumb and fingers encircling the handle as shown in Fig. H.
To guarantee a troublefree operation of the oil pump the oil guide groove (E/3) as well as the oil inlet bore in the guide bar (E/4) must be cleaned in regular intervals.
Note:
After the saw has been turned off it is normal for residual chain oil to drip from the oil feed system, the guide bar and the chain for a time. This does not constitute a defect!
Place the saw on a suitable surface.
7 |
G |
NOTE: |
When the chain brake is actuated the power supply to the motor will be cut off.
If the saw does not start when the ON/OFF switch (F/6) is actuated, it will be necessary to release the chain brake.
-Pull the hand guard (G/7) firmly in the direction of the arrow until you feel it catch.
11
Checking the chain brake
Do not work with the chain saw without first checking the chain brake!
|
- |
7 |
- |
|
- |
|
- |
I |
|
Start the motor as described (make sure you have a good footing, and place the chain saw on the ground in such a way that the guide bar is free of contact).
Grasp the tubular handle firmly with one hand and hold the grip with the other.
Switch on the motor and press the hand guard (I/7) in the direction of the arrow with the back of your hand until the chain brake engages. The chain should stop immediately. Switch the motor off Immediately and release the chain brake.
IMPORTANT: If the saw chain does not stop instantly when you carry out this test, do not under any circumstances use the saw! Take the chain saw to a DOLMAR service center.
Checking the chain lubrication
J |
Never saw when a sufficient chain lubrication is not guaranteed. Otherwise the life of the sawing device will be reduced. Before starting work check the oil level in the tank and the oil feeding. Check the fed oil quantity by following the instructions below:
-Start the electric chain saw.
-Hold the running chain saw approx. 6" (15 cm) above a trunk or the ground (use an appropriate surface).
If the lubrication is sufficient, you will see a light oiltrace because oil will be centrifuged from the chain saw.
Pay attention to the direction the wind is blowing and avoid unnecessary exposure to the oil spray!
Using the chain saw
Always be sure of your footing and hold the chain saw firmly with both hands while the motor is running.
Felling a tree
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 the tree does make contact with any utility line, the utility company should be notified immediately.
The chain saw operator should keep on the uphill side of the terrain as the tree is likely to roll or slide downhill after it is felled.
A retreat path should be planned and cleared as necessary before cuts are started. The retreat path should extend back and diagonally to the rear of the expected line of fall as shown in Fig. A. The next working place is at least 2 tree lengths away.
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 shown in Fig.B. 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.
