SAFETY INSTRUCTIONS

WARNING Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury. Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mains-operated (corded) power tool or Battery-operated power tool.

• Work area safety
  • Keep work area clean and well lit. Cluttered or dark areas invite accidents.
  • Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
  • Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
• Electrical safety
  • Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
  • Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
  • Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
  • Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
  • When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
  • If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock. NOTE The term “residual current device (RCD)” may be replaced by the term “ground fault circuit interrupter (GFCI)” or “earth leakage circuit breaker (ELCB)”.
• Personal safety
  • Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
  • Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
  • Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energising power tools that have the switch on invites accidents.
  • Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
  • Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
  • Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
  • If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards.
• Power tool use and care
  • Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
  • Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
  • Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
  • Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
  • Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
  • Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
  • Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.
• Battery tool use and care
  • Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.
  • Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
  • When battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects, that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.
  • Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.
• Service
  • Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.
• Storage
  • use of transport guard during transport and storage
  • cleaning and maintenance before storage
  • securing of the unit during transport to prevent loss of fuel, damage or injury

RECHARGEABLE BATTERY

CHARGING BATTERY(Fig.1)
Before attempting to charge the battery pack, thoroughly read all Safety Instructions. The battery needs to be charged before first use and whenever it fails to produce sufficient power on jobs that were easily done before. The battery may become warm while charging; this is normal and does not indicate a problem.
NOTE: After several charge and discharge cycles, the battery will attain full capacity.
DO NOT CHARGE THE BATTERY AT AMBIENT TEPERATURES BELOW 4ºC OR ABOVE 40ºC (BELOW 40ºF OR ABOVE 104ºF).

1. Plug cord from charger into charger base. (IMPORTANT: Do not use any other charger, only use the product comes with a charger)

2. Plug the charger into electrical outlet. The charge LED will light up green.
   ( IMPORTANT: Do not charge by means of an engine generator or DC power source.)

3. . Slide the charger onto the battery pack .The charge LED will light up red indicating that the battery is on charge.

4. When the charge LED light up green again indicating that the battery is fully charged. After the initial charge, under normal usage, your battery pack should be fully charged in 4 hours.

5. Unplug charger. Remove the charger from the charger.

IMPORTANT CHARGING NOTES

1. After normal usage, your battery pack should be fully charged in about 4 hours. Allow the battery to cool down before charging after using the saw. (NOTE: A hot battery placed in the charger will not charge)

2. DO NOT charge the battery pack in an air temperature below 40°F (4 °C) or above 104°F (40 °C). This is important and will prevent serious damage to the battery pack. Longest life and best performance can be obtained if battery pack is charged when air temperature is about 75°F (24°C).

3. While charging, the charger may hum and become warm to touch. This is a normal condition and does not indicate a problem.

4. If the battery pack does not charge properly

   • Check current at receptacle by plugging in a lamp or other appliance.
   • Check to see if receptacle is connected to a light switch which turns power off when you turn out the lights.
   • Move charger and battery pack to a surrounding air temperature of 40°F (4°C) to 104°F (40°C)
   • If the receptacle and temperature are OK, and you do not get proper charging contact (DESA Power Tools) service center.

5. The battery pack need to be charged before first using and should be recharged when it fails to produce sufficient power on jobs which were easily done previously. DO NOT CONTINUE using this product with its battery pack in a depleted condition.
   ( NOTE: After several charge and discharge cycles, the battery will attain full capacity.)

6. To prolong battery life, avoid leaving the battery pack on charger for extended periods of time (over 30 days without use). Although overcharging is not a safety concern, it can significantly reduce overall battery life.

7. The battery pack will reach optimum performance after being cycled 5 times during normal usage. There is no need to run the batteries down completely before recharging. Normal usage is the best method of discharging and recharging the batteries.

CHAIN SAW INFORMATION

CHAIN SAW ASSEMBLY
( WARNING: Cutting edges on chain are sharp. Use protective gloves when handling chain.)

1. To insert the battery pack, groove along the handle and insert in the full position, until the Battery Release Button (9) bounce back to normal position again. To remove the battery pack, withdraw it from the tool while pulling the Battery Release Button (9) down
   ( Note: Fully charge battery before using for first time.) (See Fig.2)

2. The oiler inside the oil into the chain saw’s fuel tank until oil level up to the “max” line (IMPORTANT: Fill up, you must tighten cap) (See Fig.3)

SAW CHAIN TENSION
WARNING: Remove battery from chain saw before servicing. Severe injury or death could occur from body contact with moving chain.
WARNING: Cutting edges on chain are sharp. Use protective gloves when handling chain.
WARNING: When cleaning saw body,

• do not submerge saw in any liquids
• do not use products that contain ammonia, chlorine, or abrasives
• do not use chlorinated cleaning solvents, carbon tetrachloride, kerosene, or gasoline

( Note: The saw chain tension is properly set at the factory. A new chain will stretch. Check new chain tension frequently (after disconnecting battery) during the first 2 hours of operation. Allow chain to cool down. Follow steps below to check saw chain tension.)

1. Remove battery from chain saw.
2. Place chain saw on a firm surface to check chain tension.
3. Pull chain with light force 1/8″ away from bottom of guide bar and release (See Fig 7). If chain lightly snaps back into place, tension is correct. A slight sag (1/16″ or less) between chain and bottom of guide bar is acceptable.

Saw Chain Tension Adjustment

1. Loosen tension wheel (4) before adjusting chain.
2. Turn the adjusting wheel (3) until slack is out of chain.
3. Wearing protective gloves, pull down on chain to check chain tension
4. Do not over-tension chain. Over-tensioning will cause excessive wear and will reduce the life of the guide bar and chain. Over-tensioning also reduces the amount of cuts per battery charge.
5. After chain tension is correct, tighten tension wheel (4) firmly. ( See Fig 5)

CUTTING WITH THE CHAIN SAW

1. The chain saw’s fuel tank fill up
2. Attach battery to saw.
3. Make sure section of log to be cut is not laying on ground. This will keep chain from touching ground as it cuts through log. Touching ground with moving chain will dull chain.
4. Use both hands to grip saw. Always use left hand to grip front handle and right hand to grip rear handle. Use firm grip. Thumbs and fingers must wrap around saw handles ( See Fig 6)
5. Make sure your footing is firm. Keep feet apart. Divide your weight evenly on both feet.
6. When ready to make a cut, press in trigger lockout (11) and trigger (12). This will turn chain saw on. Releasing trigger will turn chain saw off. Make sure saw is running before starting a cut. ( See Fig 6)
7. When starting a cut, place moving chain against wood. Hold saw firmly in place to avoid possible bouncing or skating (sideways movement) of saw.
8. Guide saw using light pressure. Do not force saw. The motor will overload and can burn out. It will do the job better and safer at the rate for which it was intended.
9. Remove saw from a cut with saw running. Stop saw by releasing trigger. Make sure chain has stopped before setting saw down.
10. Practice until you can maintain a steady, even cutting rate.

FELLING A TREE (Cutting Down a Tree)

WARNING:

• Avoid kickback. Kickback can result in severe injury or death.
• Do not fell a tree without ample skill or expert help.
• Keep children, animals, and bystanders away from area when felling a tree.
• If two or more persons perform bucking and felling operations at the same time, provide ample distance between operations. Provide distance of at least twice the height of tree being felled.
• When felling a tree, be aware of your surroundings. Do not endanger any person, strike utility lines, or cause property damage. If tree strikes utility lines, contact utility company at once.
• Felling is the process of cutting down a tree. Make sure your footing is firm. Keep feet apart. Divide your weight evenly on both feet. Follow directions below to fell a tree.

Before Felling a Tree

1. Before felling, inspect tree. Make sure there are no dead limbs or branches that may fall on you. Study natural lean of tree, location of larger branches, and wind direction. This will help you judge which way tree will fall.
2. Clear work area around tree.
3. Plan and clear a retreat path before felling. Make retreat path opposite to planned direction of fall of tree and at 45° angle ( See Fig 7).
4. Remove dirt, stones, loose bark, nails, staples, and wire from tree where you will make felling cuts.
5. Stay on uphill side when felling tree. Tree could roll or slide downhill after falling.

Felling Procedure

• A) Felling Notch
  A properly placed felling notch will determine direction tree will fall. Place felling notch on side of tree in direction you want tree to fall ( See Fig 8).
  Follow directions below to create a felling notch.

1. Make lower notch cut as close to ground as possible. Hold saw so guide bar is horizontal. Cut 1/3 the diameter of tree trunk ( See Fig 8). Note: Always make this horizontal lower notch cut first. If you make this cut second, tree can pinch chain or guide bar.
2. Start upper notch cut the same distance above first cut as first cut is deep. Example: If lower notch cut is eight inches deep, start upper notch cut eight inches above it. Cut downward at 45° angle. The upper notch cut should meet end of lower notch cut ( See Fig 8).
3. Remove tree trunk wedge created by notching cuts.

• B) Felling Cut

1. Make felling cut two inches higher than lower notch cut and on opposite side of tree ( See Fig 8). Keep felling cut parallel to lower notch cut.
2. Cut towards notch.
3. As felling cut nears hinge, tree should begin to fall. Note: If needed, drive wedges into felling cut to control direction of fall. If tree settles back and pinches chain, drive wedges into felling cut to remove saw. Only use wedges made of wood, plastic, or aluminum. Never use wedge made of steel. This could cause kickback and damage to chain.
4. When tree begins to fall, quickly
  * remove saw from felling cut
  * release trigger to turn saw off
  * put saw down
  * exit area using retreat path

WARNING: Do not cut all the way through tree. Leave about two inches of tree diameter uncut directly behind felling notch ( See Fig 8). This uncut portion acts as a hinge. The hinge helps keep tree from twisting and falling in wrong direction.
WARNING: Be alert for falling overhead limbs. Watch your footing while exiting area.

LIMBING A TREE
WARNING: Avoid kickback. Kickback can result in severe injury or death. See Kickback to avoid risk of kickback.
WARNING: When cutting limb that is under tension, use extreme caution. Be alert for wood springing back. When wood tension is released, limb could spring back and strike operator causing severe injury or death.

Limbing is removing branches from a fallen tree. Make sure your footing is firm. Keep feet apart. Divide your weight evenly on both feet. Do not remove larger limbs under tree that support log off ground. Remove each limb with one cut ( See Fig 9). Clear cut limbs from work area often. This will help maintain a safe work area. Make sure you start your cut where limb will not pinch saw during cutting. To avoid pinching, start cut on freely hanging limbs from above limb. Start cut on limbs under tension from under limb. If pinch occurs, turn saw off, lift limb, and remove saw.

BUCKING A LOG
WARNING:

• Avoid kickback. Kickback can result in severe injury or death. See Kickback to avoid risk of kickback.
• • If on slope, make sure log will not roll down hill. Secure log by using wooden stakes.
  Drive wooden stakes into ground on downhill side of log. Stand on uphill side of log while cutting. Log may roll after cutting.
  • Never try cutting through two logs at same time. This could increase the risk of kickback.
  • While cutting log, never hold log with your hand, leg, or foot.
  • While cutting log, never allow another person to hold log.
  • Turn off and unplug saw before moving from one place to another.

Bucking a log is cutting a log into sections. Make sure your footing is firm. Keep feet apart. Divide your weight evenly on both feet. When possible, raise log or section off ground. Do this by using limbs, logs, chocks, etc. When cutting through log, maintain control by reducing cutting pressure near end of cut. Do not relax your grip on chain saw handles. Do not let moving chain touch ground. Ground will dull moving chain. After cutting through log, release trigger to turn saw off before moving saw.
Follow directions below to buck a log.

Entire Length Of Log On Ground
Cut log from top ( See Fig 10).

Log Supported On One End

1. Make first cut on underside of log ( See Fig 11). Use top of guide bar to make this cut. Cut 1/3 through diameter of log. This cut will keep section from splintering when cut.
2. Make second cut directly above first cut. Cut down to meet first cut. This cut will keep log from pinching guide bar and chain.

Log Supported On Both Ends

1. Make first cut from above log ( See Fig 12). Cut 1/3 through diameter of log. This cut will keep section from splintering when cut.
2. Make second cut on underside of log, directly under first cut. Use top of guide bar to make this cut. Cut up to meet first cut. This will keep log from pinching guide bar and chain.

CLEANING AND MAINTENANCE

CLEANING SAW BODY

Keep saw body clean. Use a soft cloth dampened with a mild soap and water mixture. Wipe saw body to clean.

CARE OF GUIDE BAR
Uneven bar wear causes most guide bar problems. Incorrect sharpening of chain cutter and depth gauge settings often cause this. When bar wears unevenly, it widens guide bar groove (See Fig.13). This causes chain clatter and rivet popping. Saw will not cut straight. Replace guide bar if this occurs. Inspect guide bar before sharpening chain. A worn or damaged guide bar is unsafe. A worn or damaged guide bar will damage chain. It will also make cutting harder.

Normal Guide Bar Maintenance

1. Remove guide bar from chain saw.
2. Remove sawdust from guide bar groove periodically. Use putty knife or wire (See Fig.14).
3. Clean oil slots after each day of use.
4. Remove burrs from sides of guide bar. Use fl at file to make side edges square. Replace guide bar when
   • bar is bent or cracked
   • inside groove of bar is badly worn
     ( Note: When replacing guide bar, see Replacement Parts and Accessories for replacement information. See Parts Lis for correct bar.)

SHARPENING SAW CHAIN
Keep chain sharp. Your saw will cut faster and more safely. A dull chain will cause undue sprocket, guide bar, chain, and motor wear. If you must force chain into wood and cutting creates only sawdust with few large chips, chain is dull.

Items Needed to Sharpen Chain
Purchase these items from your local dealer, hardware store, or pole saw supplies outlet.

• 5/32″ round file
• Depth gauge tool
• File guide
• Vise
• Medium sized flat file

Sharpening Cutters
Use file guide for 30° filing.

1. Adjust chain for proper tension.

2. Clamp guide bar in vise to hold saw steady. (Note: Do not clamp chain.)

3. Press 5/32″ round file (attached to file guide) into groove between top plate and depth gauge on chain. File guide should rest on both top plate and depth gauge (see Fig.15).
   ( Note: File at midpoint of guide bar.)
   Note: This illustration shows file guide placement and filing direction for sharpening cutters on left side of chain.

4. Hold file guide level. Make sure 30° mark on file guide is parallel to center of guide bar (see Fig.16). This will insure that you file cutters at 30° angle.

5. File from inside towards outside of cutter until sharp. Only file in this one direction (see Fig.16). (Note: Two or three strokes with file should sharpen cutter.)

Filing Cutter Depth Gauges
The cutter depth gauge clearance is reduced as cutters are sharpened. After every second or third sharpening, reset cutter depth gauges.

1. Place depth gauge tool (.025″) firmly across top of two cutters. Make sure depth gauge enters slot in depth gauge tool (see Fig.17).
2. Use medium flat file. File depth gauge level with depth gauge tool.
3. Remove depth gauge tool. With flat file, round off front corner of cutter depth gauge (see Fig.18). After several hand filings, have authorized service center or sharpening service machine sharpen chain. This will insure even filing.

REPLACING SAW CHAIN

IMPORTANT: Do not clamp chainsaw in vise to replace saw chain or guide bar. Replace chain when cutters are too worn to sharpen or when chain breaks. Only use replacement chain noted in this manual. Always include new drive sprocket when replacing chain. This will maintain proper driving of chain. (Note: For proper chain and drive sprocket, see Parts List.)
Refer to Figure 19 while completing the following steps.

1. Loosen tension wheel.

2. Remove sprocket cover, tension wheel and adjusting wheel

3. Remove saw chain.

4. Place new chain around drive sprocket, along top groove of guide bar, and around guide bar nose.
   Note: Make sure cutting edges of chain are facing in right direction. Position chain so cutting edges on top of guide bar face guide bar nose (see Fig 20 and indicator on side cover of saw).

5. Place sprocket cover into Positioning groove.

6. Locking the sprocket cover with tension wheel. (IMPORTANT: Do not spin very tight.)

7. Adjust chain tension.

8. Securely tighten tension wheel.

CAUTION: Do not place chain on saw backwards. If chain is backwards, saw will vibrate badly and will not cut.

STORAGE
If storing saw for more than 30 days, follow steps below.

1. Remove battery from chain saw.

2. Charge battery completely. (Note: It could take up to 7 hours to completely charge the battery.)

3. When battery is completely charged, remove from charger and put protective cap on battery terminals.
   IMPORTANT: To prolong battery life, avoid leaving battery on charger for extended periods of time (over 30 days without use).

4. Remove and clean guide bar and chain. Clean guide bar and chain by soaking in petroleum-based solvent or mild soap and water mixture.

5. Dry guide bar and chain.

6. Place chain in container filled with oil. This will prevent rust.

7. Wipe a thin coating of oil over surface of guide bar.

8. Wipe off outside of saw body. Do this with soft cloth dampened with a mild soap and water mixture.

9. Store chain saw and battery

   • in a high or locked place, out of children’s reach
   • in a dry place
   • in a carrying case or with scabbard over guide bar
