Saw Chain Tension

Ensure that the saw chain is correctly tensioned and the chain bar lock nut is properly

tightened before use and during cutting. • The saw chain will "stretch" with use, so it is

important to check chain tension before and during use • The saw chain cutters are very sharp – wear suitable protective gloves when handling the saw chain. • Do NOT check chain tension with the battery

installed in the tool. • Do NOT adjust chain tension with the battery installed in the tool. Correct saw chain tension is extremely important in terms of both machine efficiency and operator safety.

Check chain tension before each use. Check chain tension frequently during use – whenever the machine is put down (the battery MUST be removed first).

Checking Tension

1. Remove the battery from the tool.

2. The saw chain should fit snugly into the groove in the chain bar and it must be possible to pull the chain

along the bar by hand. You should be able to lift the saw chain just out of the chain bar groove without excessive effort.

3. If the chain "sags" under the chain bar or can be lifted well out of the chain bar groove, it is too loose.

4. If the chain is snug in the chain bar groove but cannot be lifted out slightly or be pulled around the bar by

hand, it is too tight.

Adjusting Tension

1. Remove the battery from the tool.

2. Lift the edge of the chain bar lock nut (A) (this is the "unlock" position), then rotate left (anti-clockwise) to

loosen it just enough so you can lift the end of the chain bar (B) slightly.

3. Rotate the chain tension adjustment ring (C) to set the chain tension. Rotate right (clockwise) to increase

tension; rotate left (anti-clockwise) to reduce tension. If it is difficult to rotate the adjustment ring, check that the chain cover lock nut is sufficiently loosened.

4. Check chain tension and re-adjust, if necessary.

5. Firmly tighten the chain bar lock nut by hand. You should not be able to move the end of the chain bar

up or down when properly tightened.

Understanding and Avoiding "Kick-Back" and Other Reactionary Forces

Kick-back and other reactionary forces can cause loss of control of the machine and can result in

serious, even fatal injury – use the chainsaw in ways to avoid kickback and other reactive forces at all times.

When the saw chain is rotating, many forces are created, such as the ability to cut. The contact point between the chainsaw and object to cut is critical. If the chainsaw is not used correctly, cutting forces may become "reactionary", in that instead of the chain rotating, a reactionary force is created. Many factors affect the occurrence and force of reaction, such as saw chain speed, contact angle, and saw chain condition.

Kick-Back

"Kick-back" is a reactionary force that causes the chain bar to rotate up and back, against the direction of cut. Kick-back can also be thought of as the chain cutters at the tip of the chain bar – the "kick-back zone", "digging in" to the object to be cut and momentarily stopping or significantly slowing rotation of the saw chain, which causes the chainsaw to suddenly and quickly rotate backwards towards the operator.

The chain brake handle is a safety device that is designed to apply the chain brake if the handle is moved forward. During a "kick-back" event, the sudden rotation upward of the chain bar will cause the chain brake handle to activate through inertia or to contact the operator's hand or arm, therefore stopping the tool. To avoid kick-back:

• Do NOT use the tip of the saw for cutting or allow it to make contact with

any object.

• Always hold the machine firmly by both front and rear handles when

operating.

• Maintain saw chain sharpness and the correct cutter shape and cutting depth.

• Do NOT use the machine above shoulder height or in any way where the machine cannot be securely

held with both hands or the entire machine is not visible to the operator.

• Cut one piece of timber at a time.

• Use extreme caution when inserting the saw into a previous cut.

• Be alert to log shifting or other forces that may close over or pinch the saw chain.

• Stand to the side of the saw chain cutting path.

• Use extreme caution when plunge cutting.

Pull-In

"Pull-in" is a reactionary force that causes the chainsaw to pull forward in the direction of cut. Pull-in can also be thought of as the chain cutters at the bottom of the chain bar being caught, pinched or "digging in" to the object to be cut and momentarily stopping or significantly slowing rotation of the saw chain, which causes the chainsaw to suddenly and quickly pull forward and away from the operator. To avoid pull-in:

• Ensure that the log spike (if equipped) is making good contact with the log.

• Use wedges to help prevent cuts closing in over the saw chain.

Push-Back

"Push-back" is a reactionary force that causes the chainsaw to push backward against the direction of cut. Push-back can also be thought of as the chain cutters at the top of the chain bar being caught, pinched or "digging in" to the object to be cut and momentarily stopping or significantly slowing rotation of the saw chain, which causes the chainsaw to suddenly and quickly push back towards the operator. To avoid push-back:

• Cut one piece of timber at a time.

• Avoid twisting the saw chain when withdrawing the saw from cuts.

Using the Chain Brake

The chain brake prevents the tool from running. Engage the chain brake:

• In an emergency.

• When transporting or storing the machine.

To engage the chain brake, push the chain brake handle forward until it "clicks" into position.

To release the chain brake, pull the chain brake handle backward until the brake disengages. You must disengage the chain brake to run the tool.

Testing

To check operation of the chain brake, engage it, then attempt to run the tool – it must not run. If the saw chain rotates at all during the test, do NOT use the tool – have it serviced at an authorised service centre.

Basic Cutting Guidelines

The following information are general guidelines to chainsaw use:

Removing Branches/Limbs from Fallen Trees (Limbing)

• Be alert to high kick-back dangers from other branches or tree trunk.

• Be alert to branches/limbs under tension that could move suddenly or launch when being cut.

• Do NOT stand on the log.

• Remove the thinner upper branches first, then move down the trunk to the lower larger branches.

Cutting Logs into Sections (Bucking)

• Ensure the log is stable and cannot move or roll.

• Do NOT stand on the log.

• Cut one piece of timber at a time.

• Do NOT permit another person to hold the log. Do NOT steady the log

with your legs or feet.

• When cutting logs under tension or strain, be alert to pinching the saw chain. Start by making a cut on

the compression side (1), then cut from the tension side (2).

Basic Tree Felling

• Be alert to any power lines, cable or structures.

• Maintain a minimum distance of 2.5 times the height of the tree being

felled to any other person.

• Always consider all conditions that may affect the fall direction of the

tree, including structures and/or other tress, tress condition and decay, wind direction and speed, slope of the land etc.

• Establish escape paths (A) that can be used if the tree does not fall as

expected. The paths should be clear of obstacles, including equipment, and be at 45° angles to the opposite direction of tree fall (B).

• Use extreme caution when felling trees that are decayed or rotten inside

or if the trunk is under tension due to tree weight etc.

• For large buttress roots, remove the roots before felling. When cutting into

buttress roots, cut vertically (1) first, then horizontally (2). Remove the section of root.

• Cut the felling notch (C) perpendicular (90°) to the line of fall and as close to

ground level as practical. The angled cut (5) of the felling notch should be cut first and at an approximate 45° to the trunk and should extend into the trunk approximately 20 to 25% of the trunk diameter. Then, make the horizontal cut (6) of the felling notch. Remove the section of trunk.

• Make the horizontal felling cut (7)

approximately 25 to 50mm (1 to 2") above the centre of the felling notch, and extend it into the trunk so that approximately 10% of the trunk remains uncut to create the "hinge" (E) – do NOT cut through the hinge.

• To start and control direction of the fall,

drive wooden wedges into the felling cut (7), as needed.

Saw Chain and Chain Bar

Ensure that the saw chain is correctly tensioned and the chain drive cover lock nut is properly tightened before use. • The saw chain will "stretch" with use, so it is important to

check chain tension before and during use • The saw chain cutters are very sharp – wear suitable protective

gloves when handling the saw chain. • Use replacement parts from, or recommended by, the manufacturer. •

Always replace the saw chain and/or chain bar with replacements of the correct type (see Specifications). • It is recommended to have saw chains sharpened professionally.

Inspection and Cleaning

It is essential for efficient operation and safety that the saw chain and chain bar are properly maintained. Replace the saw chain if it:

• Shows signs of damage, such as broken or chipped cutters, damaged rivets, corrosion etc.

• Can no longer be properly tensioned due to "stretch".

• Can no longer be sharpened properly.

To clean the saw chain, soak it in a proprietary saw chain cleaning solution, solvent, or mixture of ammonia and water for approximately 15 minutes to help remove dirt, grease and resin/sap. After soaking, brush the saw chain thoroughly with a saw chain brush or stiff bristle wire brush to remove any stubborn particles, then lubricate the chain.

Replace the chain bar if it:

• Shows signs of damage, such as bending, cracks, chips or corrosion.

• The top edges of the chain bar groove become worn unevenly.

• The depth of the saw chain groove is no longer deep enough for the saw chain to

seat correctly and run along the top edges of the chain bar groove.

To clean the chain bar, use a proprietary saw chain cleaning solution, solvent, or mixture of ammonia and water to help remove dirt, grease and resin/sap, particularly from within the saw chain groove (A), the lubricant inlet hole (B), and the tension adjustment wheel (C). Use suitable tools or objects to help dislodge any stubborn particles from within the saw chain groove.

To remove the saw chain and chain bar:

1. Remove the battery from the tool.

2. Loosen the chain drive cover lock nut (D) slightly, then rotate the tension adjustment ring (E) to slacken

the chain. Fully unscrew the nut and remove the cover (F). Be careful to prevent the chain bar falling out.

3. Carefully extract the saw chain (G) from the chain bar (H) groove and drive gear, then remove the chain

and chain bar.

4. Clean away any sawdust, wood particles, dirt etc from the chain drive cover, lock nut, tension adjustment

mechanism etc.

Chain Lubricant

Always check the chain lubricant level before using the machine and ensure it is at or close to the recommended level. • Use a suitable chainsaw lubricant. • Do NOT operate the machine without

adequate chain lubricant – failure to do so will damage the saw chain, chain bar and/or other parts of

the machine, and is not covered under warranty.

To check chain lubricant level:

1. Place the machine on a flat and level surface.

2. Lubricant will be visible through the lubricant tank. There is a minimum level mark on the tank. To add chain lubricant:

1. Remove (rotate left) the chain lubricant tank cap (A).

2. Using a funnel, carefully add chain lubricant to the tank (B) until its level is close to the filler hole.

3. When finished, re-install (rotate right) the chain lubricant tank cap until firm. Wipe off any residual oil from

the machine.
