Operation
• Kickback hazard:
Kickback may occur when the moving saw chain
at the nose or tip of the guide bar touches an
object, or when the wood closes in and pinches
the saw chain in the cut. Tip contact in some
cases may cause a lightning-fast reverse
reaction, kicking the guide bar up and back
towards the operator.
• Pushback hazard:
Pinching the saw chain along the top of the
guide bar may push the guide bar rapidly back
towards the operator.
• Do not operate tool with a damaged or worn saw
chain. An improperly sharpened, dull, worn or
damaged saw chain increases the risk of
kickback and pushback.
Failure to observe these warnings could result in
severe injury or death.
Kickback (See Figures 5 and 6)
Kickback occurs when the upper portion of the guide bar
nose contacts a solid object or is pinched. The reaction
of the cutting force of the chain causes a rotational force
on the chain saw in the direction opposite to the chain
movment. This may fling the bar up and back in an
uncontrolled arc, mainly in the plane of the bar. Under
some cutting circumstances the bar may move violently
towards the operator. Kickback may also occur when
the guide bar nose is pinched, caught, encounters a
foreign object, or is incorrectly used when cutting.
Pistol Grip Chain Saw
Many factors influence the occurrence and force of the
kickback reaction. These include chain speed, the
speed at which the bar and chain contact the object, the
angle of contact, the conditions of the chain, and other
factors.
To Avoid Kickback:
1. Hold the chain saw firmly with both hands and
maintain a firm, secure grip.
2. Be aware of the location of the guide bar nose at all
times.
3. Do not let the guide bar nose contact any object. Do
not cut limbs with the guide bar nose. Be especially
careful when cutting small, tough limbs, small size
brush and saplings which may easily catch the saw
chain.
4. Do not overreach to cut.
5. Do not cut above shoulder height.
6. Always begin and continue the cut at full chain
speed.
7. Cut only one limb at a time.
8. Use extreme caution when re-entering a previous
cut.
9. Be alert for the shifting of the limb or other forces
that may cause the cut to close and pinch the saw
chain.
10. Maintain the saw chain properly. Always cut with a
properly sharpened saw chain and maintain proper
saw chain tension at all times.
11. Always stand to the side of the cutting path of the
saw chain.

Pushback (See Figure 7)
Pushback occurs when the saw chain on the top of
the guide bar is suddenly stopped by being pinched,
caught or encountering a foreign object in the wood.
The reaction of the chain may push the saw violently
straight back towards the operator. Pushback occurs
when the top of the guide bar is used for cutting.
To Avoid Pushback:
1. Be alert to forces or situations that may cause the
wood to pinch the top of the saw chain.
2. Cut only one limb at a time.
3. Do not twist the saw when withdrawing the guide
bar from the cut.
Figure 7
Pushback
Pull-In (See Figure 8)
Pull-in occurs when the saw chain on the bottom of
the guide bar is suddenly stopped by being pinched,
caught or encountering a foreign object in the wood.
The reaction of the chain may pull the saw violently
forward. Pull-in occurs when the chain is not rotating at
full speed before it contacts the wood.
To Avoid Pull-In:
1. Always begin and continue the cut at full chain
speed.
2. Always begin the cut with the front of the saw head
body in contact with the wood.

Maintenance Schedule
Pistol Grip Chain Saw
The service life of the chain saw will be maximized by
proper care and maintenance. The maintenance schedule below is recommended.
Inspect saw chain every operating day. Do not
operate tool with a damaged or worn saw chain.
An improperly sharpened, dull, worn or damaged
saw chain increases the risk of kickback and
pushback.
Failure to observe this warning could result in
severe injury or death.
Inspect hydraulic hoses and couplings every
operating day. Repair or replace if leakage,
cracking, wear, or damage is evident. Damaged
hoses or couplings can fail resulting in injury or
property damage.
Chain Saw
Daily:
1. Wipe all saw surfaces clean of grease, dirt and
foreign material.
2. Inspect the saw chain mounted on the saw before
and frequently during use. Chain must be properly
sharpened and have no worn or damaged components. AN IMPROPERLY SHARPENED, DULL
WORN AND/OR DAMAGED CHAIN INCREASES
THE RISK OF KICKBACK.
3. Inspect the hydraulic system hoses and fittings for
signs of leaks, cracks, wear, or damage. Replace if
necessary.
4. Check the saw chain tension before and frequently
during use. Adjust as often as necessary. LOOSE
CHAINS INCREASE THE RISK OF KICKBACK.
5. Check the automatic chain oiler before and frequently during use. The chain will give off a fine
spray of oil at the guide bar nose if the oiler is
working properly. Insufficient lubrication can ruin the
saw chain and/or guide bar.
6. To prevent contamination, always install dust caps
over the hydraulic couplers of the chain saw when
disconnected.
Monthly:
Automatic Chain Oiler
The automatic chain oiler provides a constant supply of
oil to lubricate the guide bar and chain whenever the
saw is operating. A metering screw controls the amount
of oil supplied. The metering screw is preset at the
factory, but may be adjusted to increase or decrease
the oil output volume. Insufficient lubrication can ruin
the saw chain and/or guide bar.
Checking Automatic Oiler Setting
1. Operate the chain saw without cutting any wood.
Notice the guide bar nose while operating.
A. If the saw chain gives off a fine spray of oil, the
oiler is working properly.
B. If the saw chain does not give off a fine spray of
oil, the oiler may need to be adjusted.
Note: Before adjusting the automatic oiler output,
always make sure the oil passage in the base of
the guide bar is cleaned first. If oil drips off the
saw head, sprocket cover and/or base of the bar,
the oil passage in the bar may be plugged.
Adjusting Automatic Oiler Setting
(See Figures 1 and 2)
1. STOP THE POWER SOURCE.
2. Turn the metering screw (15) clockwise to decrease
or counterclockwise to increase oiler output flow.
Limit adjustment to 1/2 turn at a time.
3. Start the power source. Recheck the automatic oiler
setting.
Perform a detailed inspection of the system hoses and
fittings as stated in Appendix A–S.A.E. Standard J1273,
May 1986. Replace the hoses and/or fittings if necessary.

should pull easily. If it cannot be pulled, it may be
adjusted too tight, bar groove may be damaged,
chain drive links may be damaged, or hydraulic
pressure may be trapped in the saw motor. If there
is pressure in the motor, the hoses were disconnected improperly and the pressure must be
released. See Hose Connection, Disconnecting
Hoses for proper procedure.
3. Pull the saw chain on the bottom of the guide bar
(approximately 2 lb. load). There should be 1/8 inch
(3.2 mm) chain clearance at the center of the bar. If
not, chain tension adjustment is necessary
Saw Chain – Adjusting Tension (See Figures 1 and 2)
1. Loosen the two guide bar mounting screws (6).
2. Turn the saw chain tension adjusting screw (5) until
the proper chain tension is achieved.

Filing Depth Gauges
1. If the cutters are sharpened with a file holder, check
and lower the depth gauges before sharpening the
cutters.
2. Check the depth gauges every third sharpening.
3. See Figure 10. Place the depth gauge tool on the
cutter. If the depth gauge projects, file it level with
the top of the tool. Always file from the inside of the
saw chain toward an outside cutter.
Figure 10
Lowering Depth Gauges
4. See Figure 11. 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. See Figure 13. File the cutters on one side of the
saw chain from the inside out. File on the forward
stroke only.

Guide Bar
1. The guide bar groove should be cleaned every time
the saw chain is removed or at regular intervals.
This can be done with any instrument small enough
to fit in the groove. Run the instrument along the
groove to remove all the residue.
2. The oil passage in the base of the guide bar should
be cleaned every time the saw chain is removed or
at regular intervals to ensure proper lubrication to
the chain and bar. This can be done with any
instrument small enough to insert into the passage.
Remove all the residue.
3. The guide bar should be turned from top to bottom
every time the saw chain is removed or at regular
intervals to help ensure even guide bar rail and
groove wear.
4. The guide bar rails should be checked for wear at
regular intervals.
A. Place a straight edge against the side of the
guide bar and one cutter.
B. If the saw chain is straight and there is clearance
between the guide bar and straight edge, the
guide bar rails are good. See Figure 15.
C. If the saw chain leans and there is no clearance
between the guide bar and straight edge, the
guide bar rails are worn. See Figure 16. Replace
the bar.
Drive Sprocket and Spacer
See Parts illustration. Inspect the drive sprocket and
spacer (29) every time the saw chain is removed or at
regular intervals. A worn drive sprocket and/or spacer
will damage and weaken a saw chain.

Pistol Grip Chain Saw
Before You Begin
1. Tool must be connected to the correct power source
system. See Tool Specifications for the type of
hydraulic system required. Verify the power source
hydraulic system.
2. Verify that the pressure and return hoses are
connected properly to the tool and power source
ports.
3. Power source reservoir must be filled to FULL level
with hydraulic fluid.
4. Start the power source. All power source
shut-off devices must be engaged or opened
(clutch-engaged, separate on/off valves open, etc.).
5. After verifying all of the above, check the tool to see
if it operates.
If the tool does not operate, it will be necessary to
pinpoint the tool, hose or power source as the
problem area. The following steps will help to
determine the problem area.
Determine the Problem Area
1. Stop the power source. Disconnect the existing tool
from the hoses and power source.
2. Connect a known working tool to the hoses and
power source. See the tool’s operator’s manual for
correct hook-up procedure. Start the power source.
If the known working tool operates, the problem is in
the disconnected tool. See the troubleshooting
charts in this operator’s manual.
If the known working tool does not operate, the
problem is likely to be in the hoses or the power
source. Proceed to Step 3.
3. Stop the power source. Disconnect the existing
hoses from the known working tool and power
source.
4. Connect a different set of hoses to the known
operating tool and power source. Start the power
source.
If the known working tool operates with the different
set of hoses, the problem is in the disconnected
hoses.
If the known working tool does not operate, the
problem is in the power source. See your power
source operator’s manual for troubleshooting.

IMPORTANT
Procedure for disconnecting tool, removing
hydraulic lines, fittings or components:
1. Stop the power source.
2. Depressurize the hydraulic system.
3. Disconnect hydraulic hoses from tool. Remove
lines, fittings or components slowly to release
any trapped pressure.
The disassembly procedure is divided into sections of
the tool. Complete disassembly of the tool is seldom
necessary. Disassemble only the area(s) necessary to
correct the problem. See Parts illustration for identification of parts as they are removed.
Disassembly should be done on a flat, clean surface.
Some parts may fall free during disassembly. To
prevent part loss or damage, keep the tool as close to
the working surface as possible.
Inspect all parts as they are disassembled and mating
parts in the tool that are not removed for signs of
damage, wear, cracks, etc. Replace any parts which
appear to be damaged.
When removing O-rings which must slide over sharp
surfaces, be careful not to damage the O-rings. Use a

SELECTION, INSTALLATION AND MAINTENANCE OF
HOSE AND HOSE ASSEMBLIES
- SAE J1273 MAY 1986*
SAE RECOMMENDED PRACTICE
The following recommendations on selection, installation
and maintenance of hose and hose assemblies was
established by the S.A.E. in 1979 and reaffirmed May
1986. Please read these general instructions carefully.
1. SCOPE
Hose (also includes hose assemblies) has a finite life and
there are a number of factors which will reduce its life.
This recommended practice is intended as a guide to
assist system designers and/or users in the selection,
installation, and maintenance of hose. The designers and
users must make a systematic review of each application
and then select, install, and maintain the hose to fulfill the
requirements of the application. The following are general
guidelines and are not necessarily a complete list.
Improper selection, installation or maintenance
may result in premature failures, bodily injury, or
property damage.
2. SELECTION
The following is a list of factors which must be considered
before final hose selection can be made.
2.1 Pressure - After determining the system pressure,
hose selection must be made so that the recommended
maximum operating pressure is equal to or greater than
the system pressure. Surge pressures higher than the
maximum operating pressure will shorten hose life and
must be taken into account by the hydraulic designer.
2.2 Suction - Hoses used for suction applications must be
selected to insure the hose will withstand the negative
pressure of the system.
2.3 Temperature - Care must be taken to insure that fluid
and ambient temperatures, both static and transient, do
not exceed the limitations of the hose. Special care must
be taken when routing near hot manifolds.
2.4 Fluid Compatibility - Hose selection must assure
compatibility of the hose tube, cover, and fittings with fluid
used. Additional caution must be observed in hose selection for gaseous applications.
2.5 Size - Transmission of power by means of pressurized fluid varies with pressure and rate of flow. The size
of the components must be adequate to keep pressure
losses to a minimum and avoid damage to the hose due
to heat generation or excessive turbulence.
2.6 Routing - Attention must be given to optimum routing
to minimize inherent problems.
2.7 Environment - Care must be taken to insure that the
hose and fittings are either compatible with or protected
from the environment to which they are exposed. Environmental conditions such as ultraviolet light, ozone, salt
water, chemicals, and air pollutants can cause degradation and premature failure and, therefore, must be considered.
2.8 Mechanical Loads - External forces can significantly
reduce hose life. Mechanical loads which must be considered include excessive flexing, twist, kinking, tensile or
side loads, bend radius, and vibration. Use of swivel type
fittings or adapters may be required to insure no twist is
put in the hose. Unusual applications may require special
testing prior to hose selection.
2.9 Abrasion - While a hose is designed with a reasonable level of abrasion resistance, care must be taken to
protect the hose from excessive abrasion which can result
in erosion, snagging and cutting of the hose cover.
Exposure of the reinforcement will significantly accelerate
hose failure.
2.10 Proper End Fitting - Care must be taken to insure
proper compatibility exists between the hose and coupling
selected based on the manufacturer’s recommendations
substantiated by testing to industry standards such as
SAE J517d (November, 1976).
2.11 Length - When establishing proper hose length,
motion absorption, hose length changes due to pressure,
as well as hose and machine tolerances must be considered.
2.12 Specifications and Standards - When selecting hose,
government, industry, and manufacturer’s specifications
and recommendations must be reviewed and applicable.
2.13 Hose Cleanliness - Hose components vary in
cleanliness levels. Care must be taken to insure that the
assemblies selected have an adequate level of cleanliness for the application.
2.14 Electrical Conductivity - Certain applications require
that the hose be non-conductive to prevent electrical
current flow. Other applications require the hose to be
sufficiently conductive to drain off static electricity. Hose
and fittings must be chosen with these needs in mind.

3. INSTALLATION
After selection of proper hose, the following factors must
be considered by the installer.
3.1 Pre-Installation Inspection - Prior to installation, a
careful examination of the hose must be performed. All
components must be checked for correct style, size, and
length. In addition, the hose must be examined for
cleanliness, I.D. obstructions, blisters, loose cover, or any
other visual defects.
3.2 Follow Manufacturers’ Assembly Instructions.
3.3 Minimum Bend Radius - Installation at less than
minimum bend radius may significantly reduce hose life.
Particular attention must be given to preclude sharp
bending at the hose/fitting juncture.
3.4 Twist Angle and Orientation - Hose installations must
be such that relative motion of machine components
produces bending of the hose rather than twisting.
3.5 Securement - In many applications, it may be necessary to restrain, protect, or guide the hose to protect it
from damage by unnecessary flexing, pressure surges,
and contact with other mechanical components. Care
must be taken to insure such restraints do not produce
additional stress or wear points.
3.6 Proper Condition of Ports - Proper physical installation of the hose requires a correctly installed port connection while insuring that no twist or torque is put into the
hose.
3.7 Avoid External Damage - Proper installation is not
complete without insuring tensile loads, side loads,
kinking, flattening, potential abrasion, thread damage, or
damage to sealing surfaces are corrected or eliminated.
3.8 System Check Out - After completing the installation,
all air entrapment must be eliminated and the system
pressurized to the maximum system pressure and
checked for proper function and freedom from leaks.
Note: Avoid potential hazardous area while testing.
4. MAINTENANCE
Even with proper selection and installation, hose life
may be significantly reduced without a continuing maintenance program. Frequency should be determined by the
severity of the application and risk potential.
A maintenance program should include the following as a
minimum.
4.1 Hose Storage - Hose products in storage can be
affected adversely by temperature, humidity, ozone,
sunlight, oils, solvents, corrosive liquids and fumes,
insects, rodents and radioactive material. Storage areas
should be relatively cool and dark, and free of dust, dirt,
dampness and mildew.
4.2 Visual Inspection - Any of the following conditions
requires replacement of the hose:
(a) Leaks at fitting or in hose. (Leaking fluid is a fire
hazard).
(b) Damaged, cut or abraded cover. (Any reinforcement
exposed).
(c) Kinked, crushed, flattened or twisted hose.
(d) Hard, stiff, heat cracked or charred hose.
(e) Blistered, soft degraded or loose cover.
(f) Cracked, damaged, or badly corroded fittings.
(g) Fitting Slippage on hose.
4.3 Visual Inspection - The following items must be
tightened, repaired, or replaced as required:
(a) Leaking port conditions.
(b) Clamps, guards, shields.
(c) Remove excessive dirt buildup.
(d) System fluid level, fluid type, and any air entrapment.
4.4 Functional Test - Operate the system at maximum
operating pressure and check for possible malfunctions
and freedom from leaks.
Note: Avoid potential hazardous areas while testing.
4.5 Replacement Intervals - Specific replacement intervals must be considered based on previous service life,
government or industry recommendations, or when
failures could result in unacceptable down time, damage,
or injury risk.
