WORX WG384 & WG384.9 Cordless Chain Saw

1) Work Area Safety

• Keep work area clean and well lit. Cluttered or dark areas invite accidents.
• Do not operate power tools in explosive atmospheres (e.g., near flammable liquids, gases, or dust). Power tools create sparks that can ignite dust or fumes.
• Keep children and bystanders away while operating. Distractions can cause loss of control.

2) Electrical Safety

• Power tool plugs must match the outlet. Never modify the plug. Do not use adapter plugs with grounded tools.
• Avoid body contact with grounded surfaces (pipes, radiators, ranges, refrigerators).
• Do not expose power tools to rain or wet conditions.
• Do not abuse the cord. Never use the cord for carrying, pulling, or unplugging. Keep cords away from heat, oil, sharp edges, or moving parts.
• When operating outdoors, use an extension cord suitable for outdoor use.
• If operating in a damp location is unavoidable, use a residual current device (RCD) protected supply.

3) Personal Safety

• Stay alert, watch what you are doing, and use common sense. Do not use while tired or under the influence of drugs, alcohol, or medication.
• Use personal protective equipment. Always wear eye protection. Use dust masks, non-skid shoes, hard hats, or hearing protection as appropriate.
• Prevent unintentional starting. Ensure the switch is off before connecting to power or battery pack, or when picking up/carrying the tool.
• Remove any adjusting key or wrench before turning the tool on.
• Do not overreach. Maintain proper footing and balance.
• Dress properly. Do not wear loose clothing or jewelry. Keep hair, clothing, and gloves away from moving parts.
• If dust extraction facilities are provided, ensure they are connected and used properly.

4) Power Tool Use and Care

• Do not force the tool. Use the correct tool for your application.
• Do not use the tool if the switch does not turn it on and off.
• Disconnect the plug from the power source and/or battery pack before making adjustments, changing accessories, or storing.
• Store idle tools out of reach of children and untrained persons.
• Maintain power tools. Check for misalignment, binding, or breakage. Have damaged tools repaired.
• Keep cutting tools sharp and clean.
• Use the tool, accessories, and bits in accordance with instructions, considering working conditions.

5) Battery Tool Use and Care

• Recharge only with the manufacturer-specified charger.
• Use power tools only with specifically designated battery packs.
• When not in use, keep battery packs away from metal objects (paper clips, coins, keys, nails, screws) that can cause short circuits.
• Under abusive conditions, liquid may eject from the battery; avoid contact. Flush with water if contact occurs; seek medical help for eye contact.
• Have your power tool serviced by a qualified repair person using only identical replacement parts.

1. Felling a Tree

When felling, ensure a safe distance between persons performing felling and bucking operations (at least twice the tree height). Do not fell trees in a way that endangers anyone or strikes utility lines. Notify the company if a tree contacts a utility line. Operate from the uphill side of the terrain. Plan and clear an escape path diagonally to the rear. Consider the tree's natural lean, branch location, and wind direction. Remove dirt, stones, loose bark, nails, staples, and wire from the tree.

2. Notching Undercut

Make the notch 1/3 the diameter of the tree, perpendicular to the direction of fall. Make the lower horizontal cut (W) first to avoid pinching the chain or guide bar when making the second notch (X).

3. Felling Back Cut

Make the felling back cut (Y) at least 2 inches higher than the horizontal notching cut, parallel to it. Leave enough wood for a hinge to prevent the tree from twisting. Do not cut through the hinge. If the tree doesn't fall as desired or rocks back, stop cutting and use wedges (Z) to open the cut and guide the fall. Remove the saw, stop the motor, and use the planned retreat path. Be alert for falling limbs.

4. Limbing a Tree

Limbing is removing branches from a fallen tree. Leave larger lower limbs to support the log. Remove small limbs in one cut.

5. Bucking a Log

Bucking is cutting a log into lengths. Ensure firm footing and balanced weight. If possible, support the log. When the log is supported along its entire length (Figure 3), cut from the top (overbuck), avoiding contact with the ground.

When the log is supported on one end (Figure 5), cut 1/3 the diameter from the underside (underbuck) (1), then finish with an overbuck cut (2).

When the log is supported on both ends (Figure 6), cut 1/3 from the top (overbuck) (1), then underbuck (2) the lower 2/3 to meet the first cut.

Chain and Guide Bar Assembly

1. Unpack all parts. Remove the chain cover by turning the chain tensioning knob counter-clockwise.
   [Diagram: Figure A1 shows removing the chain cover by turning the tensioning knob (1) counter-clockwise.]
2. Place the chain saw on a solid, level surface.
3. Use only genuine WORX chains or those recommended for the guide bar.
4. Slide the chain in the slot around the guide bar. Ensure the chain is in the correct running direction by comparing it to the chain icon on the guide bar or the chain direction symbol on the saw body. Ensure the bar tensioning plate is facing outward.
   [Diagram: Figure A2 shows the bar tensioning plate (24).]
5. Fit the chain onto the drive sprocket, aligning the fastening bar hole and bar locating tabs with the sprocket's keyway.
   [Diagram: Figures B1 and B2 illustrate fitting the chain onto the drive sprocket.]
6. Ensure all parts are seated properly. Make sure drive links are fully seated in the drive sprocket, avoiding kinks. If a kink occurs, lift the chain at the guide bar and pull the kink out.
   [Diagram: Figure C1 shows correctly seated drive links. Figure C2 illustrates a kink and how to avoid it.]

   NOTE: Chain should rotate freely and be free of kinks.

7. Fit the chain cover and tighten by turning the chain tensioning knob clockwise until tight.
   [Diagram: Figure D shows fitting and tightening the chain cover.]
8. The chain will stretch while cutting. If it becomes loose, unscrew the tensioning knob or turn it counter-clockwise three full turns, then retighten to reset tension.
   [Diagram: Figures E1 and E2 demonstrate chain tensioning. E1 shows tilting the saw forward. E2 shows checking tension by lifting the chain.]

   WARNING:

   The chain is not yet tensioned. Tensioning the chain applies as described under "TENSIONING CHAIN". The chain now needs to be inspected to make sure it is properly tensioned.

   Tensioning Chain

   NOTE: New saw chains will stretch. Check tension frequently and tighten when loose.

   • WARNING: Remove the battery pack before adjusting chain tension. Cutting edges are sharp; use protective gloves. Maintain proper chain tension to avoid kickback, jumping out of the groove, and rapid wear.
   • Place the chain saw on a flat surface.
   • Turn the chain tensioning knob clockwise until hand tight. The built-in ratchet mechanism prevents loosening.
   • Tilt the saw forward so the guide bar tip is pushed down to remove slack.
   • Fully tighten the chain tensioning knob clockwise.
   • Double-check tension: The chain should be liftable approximately half the drivelink depth from the guide bar.
     [Diagram: Figure E2 shows checking chain tension.]

     NOTE: The chain is properly tensioned when it can be lifted off the guide bar and the drivelink is within the guide bar rail.

     NOTE: The chain will stretch. If it becomes loose, repeat steps 1-4.

Lubrication (See Fig. F)

IMPORTANT:

The chain saw is not filled with oil. It is essential to fill with oil before use. Never operate without chain oil or with an empty tank, as this will cause extensive damage.

NOTE: Chain life and cutting capacity depend on optimum lubrication. The chain is automatically oiled during operation.

Checking the Automatic Oiler

Run the chain saw and point the guide bar tip at cardboard. An increasing oil pattern indicates the oiler is working. If no pattern develops despite a full reservoir, contact WORX customer service.

CAUTION:

Do not touch the ground with the chain. Ensure safety clearance of 30cm.

Filling Oil Tank

WARNING:

Remove the battery pack before filling the oil tank.

1. Set chain saw on a surface with the oil filler cap facing upward.
2. Clean the area around the oil filler cap and unscrew the cap counter-clockwise.
3. Add bar and chain oil until the tank is full.
4. Avoid dirt or debris entering the tank. Refit the cap and tighten clockwise.

IMPORTANT:

Small breather channels in the cap prevent leakage and ensure the machine can be left horizontally. Use only recommended standard bar and chain oil (Grade: ISO VG32). Never use recycled/old oil. Use of non-approved oil voids the warranty.

Do not swallow. If swallowed, call a physician immediately. Keep out of reach of children. Store away from heat or open flame.
