Description
Fairmont Chain Saws are hydraulically powered
cutting tools intended for pruning, limbing, and felling
operations.
Powered by a rugged, direct-drive gear motor, this
type of saw provides extraordinary cutting power for
trimming and cutting from an aerial device or from the
ground.
This saw can be customized in two ways. First, the
control handle can be set to different positions —
horizontal, 30° and 60° — for the benet of the operator.
Second, the blade and bar can be replaced with a blade
and bar of a different length or pitch to adapt to various
cutting situations. For blade-and-bar combinations that
are compatible with this saw, see Accessories in the
Specications and Parts manual.
The Greenlee Fairmont Super Spool™ allows these saws
to be used on either Open-Center or Closed-Center
hydraulic systems.
Super Spool™ is protected by U. S. Patent No. 4548229.

Chain Saw Basics
This section introduces some basic principles of chain
saw use (Hazard Prevention, Compression and Tension,
and Cutting Techniques). For more information on
proper tree-trimming and felling procedures, contact
the National Arborist Association at the address shown
under Safety at the front of this manual.
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.
Figure 1 – Pull-In
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.
Figure 2 – Push-Back
PUSH
Kickback
Kickback is much more hazardous than pull-in or push-
back. 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.

Chain Saw Basics (cont’d)
Preventing Pull-In, Push-Back and Kickback
The chain/bar combination and shroud are intended to
prevent or reduce the likelihood and severity of kick-
back. 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
Fairmont 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.
Figure 6
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.
Press spike rack against the limb or trunk.
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.

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, branch or tree to predict the direction
or path of fall. Be sure that no personnel are in that
area.
Some factors that will inuence the direction or path
of fall of the tree include, but are not limited to:
– weight distribution of the limbs and branches.
The weight distribution can be changed by pruning.
– the lean of the tree. A tree that leans will tend to fall
in the direction it leans.
– wind direction. Do not fell a tree in strong winds.
If working in a municipal area, plan the direction of fall
so that a limb or tree 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 tree or branch might tend to bounce or roll
downhill.
Plan and clear two emergency exit routes, in case the
tree falls in an unexpected direction.
•
•
•
•
•
•
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.

Chain Saw Basics (cont’d)
CUTTING TECHNIQUES
Pruning
Pruning is the process of cutting limbs or small
branches off of a tree. Whenever possible, prune lower
branches rst so that higher branches have a clear fall
path.
When pruning, the compression is along the bottom of
the limb or branch. Make the rst cut at the bottom, and
nal cut at the top of the branch.
Felling
Felling refers to cutting a tree down. Felling a tree
consists of two cuts — a notch cut and a felling cut.
Begin by planning the direction of fall. Make the rst
cut — the notch cut — from the direction in which you
want the tree to fall. After making the notch cut, remove
the wedge-shaped piece of wood from the notch.
On the other side of the trunk, begin the felling cut
approximately two inches above the bottom of the
notch. Keeping two escape routes in mind, proceed with
the felling cut. Do not cut completely through — leave
approximately 1/10 of the diameter of the trunk to act as
a hinge. This hinge will help to control the direction of fall.
Figure 10 – Felling

45°
1/10

Limbing
Limbing is cutting limbs and branches from a fallen
tree. Keep in mind that the trunk might shift as limbs are
removed from it.
Remove limbs from the upper side of the trunk only.
Then proceed to Bucking.
Bucking
Bucking refers to cutting the fallen tree into short
sections. Make the rst bucking cut on the compression
side, and make the second cut on the tension side.
Be aware that the section may fall in an unexpected
direction when the cut is complete.
Sectioning
Sectioning is a method of bucking a fallen tree that is too
large for a single pass of the saw. See the illustrations
below.
As always, make the rst cuts on the compression side.
Make the nal cut on the tension side.

Maintenance
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.
Do not reverse hydraulic ow. Operation with
hydraulic ow reversed could cause tool malfunc-
tion. Connect the pressure hose and tank hose to the
proper ports.
SCHEDULE
Use this schedule to maximize the tool’s service life.
Notes: Keep all decals clean and legible. Replace
decals when necessary. See the Specifications and
Parts manual for decal part numbers.
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.
Monthly
1. Perform a thorough inspection of the hydraulic
hoses and ttings as described in publication
99930323, SAE J1273 (Hose and Hose Assemblies).
2. Perform the Bar Service procedure as described
under Saw Chain and Bar Maintenance.
Annually
If required by your organization’s regulations, have the
tool inspected by an Fairmont authorized service center.
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.
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. Twist the adjustment screw 1/2 turn as follows:
clockwise to decrease the oiler output.
counterclockwise to increase the oiler output.

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.

Adjusting Chain Tension
1. Loosen the two bar ange nuts.
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.
5. 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.
See Figure 19.
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.
