POLE CHAIN SAW SPECIFIC SAFETY PRECAUTIONS

• Do not rely exclusively upon the safety devices built into the saw. As a pole saw user, several steps must be taken to keep your cutting jobs free from accident or injury.
• With basic understanding of kickback, you can reduce or eliminate the element of surprise. Sudden surprise contributes to accidents.
• Keep a good firm grip on the pole chain saw with both hands. Place your right hand on the rear handle and your left hand on the outer tube assembly when operating. Use a firm grip with your thumbs and fingers encircling the chain saw handle and outer tube assembly. A firm grip helps reduce kickback and maintains control of the pole chain saw. Do not let go.
• Make sure the area in which you are cutting is free of obstructions. Never allow the nose of the guide bar to contact a branch or any other obstruction that can be accidently hit while operating the saw.
• Cut at the rated operating speeds (gpm).
• Follow the manufacturer’s sharpening and maintenance instructions for the saw chain.
• Only use replacement bars and chains specified by STANLEY or equivalent.
• Make sure you’re well rested and mentally alert before operating the pole chain saw.
• Do not start cutting until you have a clear work area, secure footing and a planned drop area for falling branches.
• Keep all parts of the body away from the saw chain during operation.
• Carry the saw with the unit de-energized.
• Do not operate a pole chain saw that is damaged, improperly adjusted or not completely and securely assembled. Make sure the chain stops moving when the control trigger is released.
• Use extreme caution when cutting small branches. Twigs may catch the saw chain and be whipped toward the operator or pull the operator off balance.
• When cutting a limb that is under tension, be aware of spring back so you will not be struck when the tension on the limb is released. Always cut on the outside arc or curve.
• Keep the handle dry, clean and free of hydraulic fluid.
• When using tools near energized transmission lines, make sure to use only hoses labeled and certified non-conductive.
• Turn off the power unit or move the hydraulic control valve to neutral before setting the pole chain saw down.
• Use a chain bar scabbard when transporting the saw.
• Know the location of buried or covered electrical services before starting work.
• To avoid personal injury or equipment damage, all tool repair, maintenance and service must only be performed by authorized and properly trained personnel.

HTMA / EHTMA REQUIREMENTS

OPERATION

PREPARATION PROCEDURES CHECK POWER SOURCE

1. Using a calibrated flowmeter and pressure gauge, make sure the hydraulic power source develops a flow of 4-6 gpm /15-22 lpm at 1500-2000 psi/105/140 bar for the CS25 or a flow of 7-9 gpm/26-34 lpm at 1000-2000 psi/70-140 bar for the CS28.
2. Make sure the power source is equipped with a relief valve set to open at 2100-2250 psi/145-155 bar.
3. Check that the dual spool valve is set to the hydraulic system type (open-center (CC) or closed-center (CC) operation).

CHECK TOOL

1. Make sure all tool accessories are correctly installed. Failure to install tool accessories properly can result in damage to the tool or personal injury.
2. There should be no signs of leaks.
3. The tool should be clean, with all fittings and fasteners tight.

CHECK TRIGGER MECHANISM

1. Check that the trigger operates smoothly and is free to travel between the ON and OFF positions.
   SETTING THE DUAL SPOOL FOR OPERATION
   This tool is furnished with an on-off spool commonly referred to as a “dual spool” which permits adjustment so the tool may be operated on either a open- center hydraulic system or a closed-center hydraulic system. The dual spool is normally set to the open-center (OC) position at time of manufacture. The dual spool can also be disabled so that the tool may be set to the open-center-only operation or closed-center-only operation. For more details, please refer to the following instructions.

2. Remove the hex plug from the bottom of the tool handle.

3. Turn the selector screw until it stops to select spool operation; clockwise for open-center (OC), counter clockwise for closed-center (CC).

4. Install hex plug into the tool handle.
   For Serial Number 080822103 and DOWN:
   To set the tool for OC system operation turn the selector screw located in the top of the valve spool fully out (counter-clockwise) until it hits the stop.
   To set the tool for CC system operation turn the selector screw located in the top of the valve spool fully in (clockwise) until it bottoms.

TO DISABLE DUAL SPOOL OPERATION AND CONVERT TO OC ONLY OPERATION
For Serial Number 080822103 and DOWN:
Turn the selector screw located in the top of the valve spool fully out (counter-clockwise) until it hits the stop.

1. Insert the small plug from the kit (furnished with the tool) into the hole located in the top of the selector screw. Tap the plug down using a small punch and hammer. DO NOT USE ANY ADHESIVES.

TO DISABLE DUAL SPOOL OPERATION AND CONVERT TO CC ONLY OPERATION
For Serial Number 080822103 and DOWN:

1. Turn the selector screw located in the top of the valve spool fully in (clockwise) until it bottoms.
2. Insert the small plug from the kit (furnished with the tool) into the hole located in the top of the selector screw. Tap the plug down using a small punch and hammer. DO NOT USE ANY ADHESIVES.

CONNECTING HOSES

1. Wipe all hose couplers with a clean lint-free cloth before making connections.
2. Connect the hoses from the hydraulic power source to the tool fittings or quick disconnects. It is a good practice to connect return hoses first and disconnect them last to minimize or avoid trapped pressure within the tool.
3. Observe the arrow on the couplers to ensure that the flow is in the proper direction. The female coupler on the tool is the inlet (pressure) coupler.
4. Move the hydraulic circuit control valve to the ON position to operate the tool.

Note : If uncoupled hoses are left in the sun, pressure increase inside the hoses can make them difficult to connect. If possible, connect the free ends of the hoses together.

OPERATION

TOOL OPERATION

The following are general woodcutting procedures and techniques. Differences in the terrain, vegetation and type of wood will make this information more or less valid for particular areas. For advice on specific wood cutting problems or techniques for your area, consult you local STANLEY representative or your county agent. They can often provide information that will make your work safer and more productive.

CUTTING TIPS

1. Check the lean of the tree. Tie a weight to a piece of string about 2 feet long. Hang the weight in your line of sight. The string is a good vertical line to help you judge the lean of a tree. The tree should fall the way the string is leaning. Trees that are straight (leaning no more than 5°) generally can be felled in any direction.
2. Check the weight distribution. A tree is heavier on the side with the most limbs. It will try to fall on its heavy side. Trim a few limbs to balance the tree.
3. Clear the work area. You need a clean area all around the tree. Get everything out of the area where the limbs might fall. Do not cut trees near structures. Because of the danger of electrocu tion, use extreme care when cutting trees near power lines.
4. The chain saw should cut with very little pressure applied to the handle. If you have to force the cut or if the cut is not straig ht, cease cutting immediately to prevent further saw chain and bar damage. See the Service manual for chain replacement, sharpening and adjustment proce dures.

FELLING OR TOPPING

1. Observe safety precautions.
   NOTCHING OR UNDERCUTTING

2. The notching or undercutting cut is made on the side you want the tree to fall.

3. Start the cut horizontally. Cut to about one-quarter of the tree’s diameter.

4. Make a diagonal cut down to meet the horizontal cut and remove the wood from the notch.

FELLING OR BACK CUT

1. The felling or back cut is made on the side opposite and at least 2 inches above the horizontal undercut (the felling cut is made higher as the size of the tree increases).

2. Start the cut horizontally parallel to the notch cut. Cut until the saw is about 1 or 2 inches from the notch. DO NOT CUT THROUGH THE NOTCH.
   Note: The uncut wood between the felling and notch cuts is called the hinge. The hinge controls the fall of the tree and should be of uniform thickness.

3. As the saw nears the back cut, watch the tree-top and the cut for signs of movement. Be alert as soon as the tree starts to move, turn off the saw, pull it from the tree and move away quickly on your escape route.

LOGS/LIMBS WITH PRESSURE ON BOTTOM

1. Observe all safety precautions.
2. Begin with a bottom-cut. The depth of the cut should be about one-third of the log diameter.
3. Finish with an upper cut, down from the top. The saw cuts should meet.

PRUNING & TRIMMING

1. Observe all safety precautions.
2. Use both hands. Keep a firm grip.
3. Be alert for kickback. Do not allow the tip of the bar to touch anything while the chain is in motion.
4. Pole chain saws must be hung securely in a vertical position to prevent dislodgement. Pole chain saws must not be hung on utility wires or cables and must not be left in the tree overnight. Pole chain saws must be hung so the sharp edge is away from the worker, if possible.
5. Warnings, when necessary, must be given by the worker in the tree before a limb is dropped. “Timber” or “heads up” are common terms used for this purpose.
6. A separate line should be attached to limbs that cannot be dropped safely or are too heavy to be controlled by hand. The line should be held by workers on the ground end of the rope. Use of the same crotch for both the safety rope and the work rope should be avoided.
7. The safety line or climbing rope must not be used for any purpose but for climbing.
8. Cut branches must not be left in trees overnight.

TOPPING/LOWERING LIMBS

1. Observe all safety precautions.
2. Use both hands. Keep a firm grip.
3. Workers performing topping operations should make sure the trees are able to stand the strain of a topping procedure. If not, some other means of lowering the branches should be provided, such as a tree crane.
4. If large limbs are lowered in sections, the worker in the tree should be above the limb being lowered.
5. Guidelines, hand lines, or tag lines must be used when conditions warrant their use.

LIMBING AND BUCKING

1. Observe all safety precautions.
2. Use both hands. Keep a firm grip.
3. When it is possible to do so, the tree worker must work on the side opposite the side on which the limb is being cut.
4. Branches bent under tension must be considered hazardous.

COLD WEATHER OPERATION
If the pole chain saw is to be used during cold weather, preheat the hydraulic fluid at low engine speed. When using the normally recommended fluids, fluid should be at or above 50 °F/10 °C (400 ssu/82 centistokes) before use.
Damage to the hydraulic system or pole chain saw can result from use with fluid that is too viscous or thick.
Cutting frozen wood causes the cutters to wear, crack and break at the back rivet hole unless proper precautions are taken. To extend chain life when cutting in cold weather:

• Be sure the automatic oiler is working.
• Keep the chain tensioned and check often.
• Keep the chain properly sharpened. Touch up at least every hour. Never force a dull chain to cut.
• Clean out the bar groove and keep the oil hole open. Turn the bar over to equalize wear on the rails.
• Always install a new sprocket with a new chain.

AUTOMATIC OILER ADJUSTMENT

1. Observe all safety precautions.

2. The automatic oiler is located in the front of the motor housing. The oil volume can be adjusted with a 3/16 inch Allen wrench by turning the plug counter-clockwise to increase output and turning clock wise to decrease output.
   Note: Oil output varies proportionally to load and operating pressure. It should be adequate for most operations as adjusted from the factory.

3. Initial oiler adjustment is made with the saw bar and chain removed.
   The following step can be hazard ous. Failure to heed the instructions could result in serious injury.

4. Connect the pole chain saw to a hydraulic power source and check for proper operation. READ THE FOLLOWING CAREFULLY BEFORE PROCEEDING.

5. Make sure the hydraulic power source is running at the lowest gpm/lpm rate it can while still producing full pressure.

6. Secure the pole chain saw firmly in a bench vise and place the correct size wrench on the 1/2-20 nut securing the sprocket.

7. Connect the hydraulic power source to the pole chain saw and turn the circuit control valve to the ON position.

8. With a firm grip on the pole chain saw and wrench, SLOWLY squeeze the trigger to ac-tivate it.

9. Adjust the oiler for a flow of approximately one drop every one to two seconds.

10. Release the trigger and remove the wrench.

CHAIN TENSION ADJUSTMENT

1. Observe all safety precautions.

2. When the chain appears loose, lubricate it well and let it cool for a few minutes to allow for contraction of the chain. Disconnect the pole chain saw from its hydraulic power source.
   Note: Perform Steps 3 through 6 while holding the top end of the saw bar upward.

3. Loosen the two saw bar nuts slightly.

4. Tighten the chain tension screw until the bot toms of the tie straps and cutters just touch the saw bar rails of the bottom of the saw bar.

5. Pull the chain around the saw bar by hand to be sure it fits the sprocket and saw bar properly. The chain should move easily.

6. Hold the saw bar tip up as you tighten the two saw bar nuts.

7. Connect the pole chain saw to a hydraulic power source. Operate the chain at low speed (gpm) for a minute or two while pumping extra oil on the chain.

8. Stop the pole chain saw and check the tension.
   If it has loosened, disconnect the pole chain saw from the hydraulic power source and perform Steps 3 through 6 again to tighten the chain to the correct tension.

9. Reconnect the pole chain saw to the hydraulic power source. Operate the saw and make a few easy cuts. Check chain tension and readjust if necessary (disconnect it from the hydraulic power source and perform Steps 3 through 6).
   Note: Never break in a new chain under a heavy cutting load.

10. Watch the chain tension carefully for the first half-hour of cutting.

In addition to the safety precautions found in this manual, observe the following for equipment protection and care.

• Make sure all couplers are wiped clean before connection.
• The hydraulic circuit control valve must be in the OFF position when coupling or uncoupling hydraulic tools. Failure to do so may result in damage to the quick couples and cause overheating of the hydraulic system.
• Always store the tool in a clean dry space, safe from damage or pilferage.
• Make sure the circuit PRESSURE hose (with male quick disconnect) is connected to the IN port. The circuit RETURN hose (with female quick disconnect) is connected to the opposite port. Do not reverse circuit flow. This can cause damage to internal seals.
• Always replace hoses, couplings and other parts with replacement parts recommended by STANLEY. Supply hoses must have a minimum working pressure rating of 2500 psi/172 bar.
• Do not exceed the rated flow. Rapid failure of the internal seals may result. See “SPECIFICATIONS” on page 19 for correct flow rate and model number.
• Always keep critical tool markings, such as warning stickers and tags, legible.
• Do not use the tool for applications it was not designed for. The chain saw is intended to cut wood only.
• Keep chain sharp for maximum tool performance.
• Tool repair should be performed by experienced personnel only.
• Make certain that the recommended relief valves are installed in the pressure side of the system.
• Do not use the tool for applications for which it was not intended.
