Skin injection hazard:
Oil under pressure easily punctures
skin causing serious injury, gan-
grene or death. If you are injured by
escaping oil, seek medical attention
immediately.
• Do not use fingers or hands to
check for leaks.
• Do not hold hose or couplers while
thehydraulicsystemispressurized.
• Depressurize the hydraulic system
before servicing.
Before operating the saw, read and
understand the following explana-
tions in this manual:
• Pull-In
Pull-in can occur when the blade
at the bottom of the bar contacts
a foreign object, such as a nail,
or when the blade is pinched in
the cut.
The saw will be suddenly and
forcefully pulled away from the
operator.
• Push-back
Push-back can occur when the
blade at the top of the bar con-
tacts a foreign object, such as a
nail, or when the blade is pinched
in the cut.
The saw will be suddenly and
forcefully pushed back toward the
operator.
• Kickback
Kickback can occur when the
chain at the guide bar tip contacts
anything. The bar of the saw will
travel upward and back, toward
the operator.
Failure to observe this warning could
result in severe injury or death.

position. Operator cannot stop tool when
trigger is locked.
• Do not remove or modify the trigger
actuator. Accidental start-up can result in
serious injury.
• Wear protective gloves when handling or
adjusting the chain. The chain can cut even
when stationary.
Failure to observe these warnings could result
in severe injury or death.
Wear foot protection when using this

1SAFETY
Read and understand all of the instructions
and safety information in this manual before
operating or servicing this tool.
1.1 SAFETY
Safety is essential in the use and maintenance of
RGC tools and equipment. This instruction manual and any decals on the tool
provide information for avoiding hazards and unsafe practices related to the use of this tool. Observe all of the safety
information provided.
1. Only trained personnel shall operate the saw or do repairs. A trained person is one who has read and thoroughly
understands this instruction manual and related equipment manuals and, through training and experience, has shown
knowledge regarding the safe operational procedures.
2. Sawing area must be kept clear of unauthorized personnel at all times. Place barricades or secure the area with signs
and a roped boundary to prevent personnel injury.
3. Never use the saw in an explosive atmosphere and/or near combustible material that could be ignited by a spark.
4. Do not use a saw that shows any signs of damage. Do not use the saw if the chain does not stop rotating when the
power-activating trigger lever is released.
5. The guard provides protection against contact with moving parts, ejected debris, broken chain, thrown water and
concrete slurry. Never run the saw without the chain guard in place.
6. Never allow anyone to stand in front of, or in line with, the chain forward of the guard.
7. Always use safety footwear, a snug fitting wet suit, safety goggles or face shields, and hearing and head protection
devices. Safety shoes MUST provide good footing to prevent slipping or falling down. Gloves protect the hands
from chips and should be worn.
8. Do not use the saw when you are tired or fatigued.
9. Never operate the saw under the influence of drugs, alcohol, or medication.
10. Always carry the saw in its de-energized state.
11. Keep the saw handles dry, clean, and free of oil or fuel.
12. Do not start cutting without first de-energizing electrical wiring near the cutting site or imbedded in the concrete.
13. Before cutting through a wall, check both sides for possible obstructions.
14. Prior to cutting, plan your cuts to prevent pinching of the bar or personnel injury from falling concrete.
15. Always hold the saw with both hands during operation. Use a firm grip on the handles.
16. Never exceed the flow and pressure rating of the saw which is 8 GPM at 2000 psi.

Hydraulic oil types are too numerous to list in this manual. If you have any question concerning the type of oil suitable for C150
operation, please consult your local supplier or Reimann & Georger Corporation for details.
2.4 NAMEPLATE AND SERIAL NUMBER TAG
It is important to identify the saw completely and accurately whenever ordering spare parts or requesting assistance in service.
The saw has a product nameplate that states the model and serial numbers. The saw label should appear as the sample nameplate
shown in Figure 2-1. Record the model and serial numbers for future reference.

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
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 forcutting.
• contacting a nail or other metal object when
cutting.
• accidental contact when cutting more than one
branch at a time.

PULL
Figure 4 – Contact with Metal Objects
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)
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 benefit from these
features. If worn or damaged, replace these items with
Greenlee Utility replacement parts.
GeneralTips:
• 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.
Figure6
Cutting Procedure:
• Hold the chain saw securely with both hands and
maintain a firm, secure grip.
• Bring the chain saw to full rpm before starting the cut.
Maintain full rpm until the cut is completely finished.
• 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.
Do notallow
the
guide bar
tip to
contact
anything.
Verifythatthe chainis sharp
andproperlytensioned.
