Chain Saw Basics

Long-Reach Chain Saws (Foam-ﬁlled)

This section introduces some basic principles of chain

saw use: Hazard Prevention, Compression and Tension.

HAZARD PREVENTION

The cutting action of this chain saw is performed by a chain-type blade driven at high speed by a powerful hydraulic motor. When used carefully and properly, the chain saw is a highly effective cutting tool.

When used improperly, or when anything interferes with the normal rotation of the blade, the operator could very suddenly and very quickly lose control of the saw. Such loss of control can result in harm to the operator. The three terms that describe loss of control are pull-in, push-back, and kickback.

Pull-In

Pull-in can occur when the blade at the bottom of the

bar is doing the cutting. If the blade is suddenly pinched

in the cut, or if it contacts a foreign object such as a nail, the saw may be suddenly and forcefully pulled away from the operator.

Pull-In

Kickback

Kickback is much more hazardous than pull-in or pushback. When kickback happens, the entire saw may rotate suddenly and forcefully. The bar of the saw may quickly travel upward and back, toward the operator.

Kickback can occur when the blade at the guide bar tip contacts anything while the chain is rotating. Some causes for kickback are:

• using the guide bar tip for cutting.

• contacting a nail or other metal object when cutting.

• accidental contact when cutting more than one

branch at a time.

Using Guide Bar Tip for Cutting

PULL

Push-Back

Push-back can occur when the blade at the top of the

bar is doing the cutting. If the blade is suddenly pinched

in the cut, or if it contacts a foreign object such as a nail, the saw will be suddenly and forcefully pushed back toward the operator.

Chain Saw Basics (cont’d)

Long-Reach Chain Saws (Foam-ﬁlled)

Preventing Pull-In, Push-Back and Kickback

The chain/bar combination and shroud are intended to

prevent or reduce the likelihood and severity of kickback. Verify that these items are in good working order (chain is sharp and properly tensioned, shroud is not damaged, etc.) to get the maximum benet from these features. If worn or damaged, replace these items with Greenlee Utility replacement parts.

General Tips:

• Maintain the saw properly. Verify that the blade is

sharp and has been properly tensioned.

• Do not allow the guide bar tip to contact anything.

• Do not over-reach.

• Do not use the saw above shoulder height.

• Cut only one limb, branch, or log at a time.

• Be aware that small-diameter limbs or branches are

more likely to catch the blade, causing pull-in or kickback.

Verify that the chain is sharp and properly tensioned.

Do not allow the guide bar tip to contact anything.

Cutting Procedure:

• Hold the chain saw securely with both hands and maintain a rm, secure grip.

• Bring the chain saw to full rpm before starting the cut.

Maintain full rpm until the cut is completely nished.

• Apply a moderate amount of downward force to the saw.

• Cut straight through. Do not twist the saw during

the cut.

• Be alert for the limb to shift, which may pinch the saw

in the cut.

• Be alert for a limb or branch under tension to spring back when the cut is complete and the tension is

released.

Cutting Procedure

Bring chain to full rpm. Maintain full rpm until the cut is ﬁnished.

Hold saw securely

Apply a moderate amount of downward force.

Chain Saw Basics (cont’d)

Site Preparation Tips

• Prepare the cutting area by clearing away brush, branches, vines, etc.

• Remove any unnecessary tools and coil up excess

hydraulic hose.

• Survey the limb or branch to predict the direction or

path of fall. Ensure that no personnel are in that area.

• If working in a municipal area, plan the direction of fall so that a limb doesn’t fall into a roadway, strike a nearby building, contact nearby power lines, etc.

• If the tree is on an incline, work uphill from the fall path. A branch might tend to bounce or roll downhill.

COMPRESSION AND TENSION

Any branch or log will have two forces acting on it— compression and tension. As the branch or log is cut, compression tends to push the two halves toward each other. Tension tends to pull the two halves apart.

See the illustrations. A log or limb supported at both ends has the compression on the top. A log or limb

supported at one end has the compression on the bottom.

Make the rst cut on the compression side. Cut through approximately 1/3 of the log’s diameter. Make the second cut on the tension side. This will decrease the likelihood that the saw will become pinched in the cut.

These additional instructions are derived from EN 50110-1:

• To avoid electrical

danger and prevent

injury or electrocution: a) the operator must

have the necessary

technical knowledge

or experience

b) the operator must

work under the

direct supervision of

another person who

has the necessary technical

knowledge or experience.

• This tool must not be used under adverse environmental conditions. These include a lightning storm, any sign of an approaching lightning storm (such as thunder), and poor visibility.

• If any electrical lines or other electrical components carry voltages greater than 50 VAC or 120 VDC, ensure that:

a) live parts cannot be touched — use screens,

barriers, an enclosure, or insulating covering

b) the “live working zone” cannot be reached

with

either parts of the body, the tool, or any

accessories.

The live working zone is the distance from any

electrically live part, based on the voltage carried by the live part. Refer to EN 50110-1, Annex A for

this information.

Maintenance

Long-Reach Chain Saws (Foam-ﬁlled)

Wear eye protection when operating

or servicing this tool.

Failure to wear eye protection could result in serious eye injury from ying

debris or hydraulic oil.

Make a note of the time it takes the chain to stop completely (stop time). Compare to the stop times

recorded during previous months.

An increasing stop time indicates that the trigger

valve components are dirty or worn. Have the tool cleaned or repaired by an Greenlee Utility Authorized Service Center.

Annually

If required by your organization, have the tool inspected by an Greenlee Utility Authorized Service Center.

Do not change accessories, inspect, adjust or clean tool when it is connected to a power source. Accidental startup can result in serious injury.

Failure to observe these warnings could result in severe injury or death.

SCHEDULE

Use this schedule to maximize the tool’s service life.

Notes: Keep all decals clean and legible. Replace decals when

necessary. When disposing of any components (hydraulic hoses,

hydraulic ﬂuid, worn parts, etc.), do so in accordance with federal, state and local laws or ordinances.

Daily

1. Wipe all tool surfaces clean.

2. Inspect the entire chain before use. Tension and

sharpen the chain as instructed under Saw Chain and Bar Maintenance. An improperly sharpened, dull, worn or damaged chain increases the risk of kickback.

3. Check the operation of the automatic oiler before use as instructed under Checking and Setting the Automatic Chain Oiler. An improperly set oiler can accelerate the wear of the chain and bar.

4. Inspect the hydraulic hoses and ttings for signs of leaks, cracks, wear or damage. Replace if necessary.

5. Install dust caps over the hydraulic ports when the

tool is disconnected.

CHECKING AND SETTING THE AUTOMATIC CHAIN OILER

The automatic chain oiler provides a constant supply of

oil to lubricate the bar and chain whenever the saw is operating. An adjustment screw controls the amount of

oil supplied.

Before adjusting the automatic oiler, clean the oil

passage in the base of the guide bar rst. Oil dripping

off the saw head, sprocket cover or bar indicates that

the oil passage is plugged.

1. Run the saw at full rpm.

2. If the tip of the saw gives off a ne spray of oil, the automatic oiler is working properly. If the saw does not give off a spray of oil, adjust the oiler.

Note: For better results, hold saw so that the tip of the saw blade is pointing toward a clean sheet of paper or cardboard and run the saw at full rpm. If the automatic oiler is working properly, the paper or cardboard should soon show small droplets of oil.

3. Stop the hydraulic power source.

4. Fully tighten the oiler screw until it is seated. Loosen1/4 turn counterclockwise.

SAW CHAIN AND BAR MAINTENANCE

New Chain Break-In

1. Run the saw at low chain speed without cutting wood for 2 to 3 minutes. Check the output from the

automatic oiler.

2. Stop the hydraulic power source. Disconnect the hoses. Allow the bar and chain to cool. Check the tension and adjust if necessary.

3. Connect the hoses. Start the power source. Make a few easy cuts at moderate chain speed.

4. Stop the hydraulic power source. Disconnect the hoses. Allow the bar and chain to cool. Check the tension and adjust if necessary.

5. Connect the hoses. Start the power source. Use the saw for moderate cuts during the next 30 minutes of

use.

Checking Chain Tension

1. Stop the hydraulic power source. Disconnect the hoses. Allow the bar and chain to cool.

2. Pull the saw chain around the bar. The chain should rotate around the bar easily. If it does not, see Chain

is Difcult to Rotate Manually in the Troubleshooting table.

3. Check the tension as follows:

Pull the saw chain away from the bar (see the

illustration) using approximately 4.4 Newtons (2 lb) of force. The clearance between the chain and bar should be approximately 3.2 mm (1/8"). If there is too much or too little clearance, proceed to Adjusting Chain Tension.

Proper Chain Tension

Adjusting Chain Tension

1. Loosen the two guide bar mounting screws.

2. Turn the saw chain tension adjusting screw until the proper tension is achieved, as follows:

Pull the saw chain away from the bar (see the

illustration) using approximately 4.4 Newtons (2 lb) of force. The clearance between the chain and bar should be approximately 3.2 mm (1/8").

3. Hold the bar nose up and tighten the two bar ange nuts. Torque to 16.9 Newton-meters (150 in-lb).

4. Check the chain tension again.

Rotate the chain around the bar manually. If you hear

a clicking noise, the chain drive links are hitting the bar. Repeat the Adjusting Chain Tension procedure.

Bar Service

1. Mark the top side of the bar with a grease pencil or marker.

2. Remove the chain and bar. Use a small cleaning

brush to remove all residue from the bar groove.

3. Clean the oil passage at the base of the guide bar.

Use any instrument small enough to thoroughly

clean the passage.

4. Check the bar rails for wear by placing a straight

edge against the side of the bar and one cutter.

• Clearance between the bar and straight edge

indicates that the bar rails are not worn.

• If the chain leans and there is little or no clearance

between the bar and straightedge, the bar rails are worn and the bar should be replaced.

Filing Depth Gauges

1. If the cutters are sharpened with a le holder, check and lower the depth gauges before sharpening the

cutters.

2. Check the depth gauges every third sharpening.

3. Place the depth gauge tool on the cutter. If the

depth gauge projects, le it level with the top of the tool. Always le from the inside of the saw chain toward an outside cutter.

Lowering Depth Gauges

4. Round off the front corner to maintain the original shape of the depth gauge after using the depth

gauge tool. Always follow the recommended depth

gauge setting of the chain manufacturer. This is important for maximum performance throughout

the saw chain’s life as well as for protection against kickback.

2. Guide the le at a 10° angle to the cutters.
