   Check

2. Pull the chain around the bar by hand. You should be able to easily pull the chain around the bar. If the chain does not move, loosen the chain.

3. Measure how far the chain links hang from the saw bar.

4. If the links hang from the bar more than 1/2 inches (12 mm), then you must tighten the chain.
   Adjust

5. Loosen the side cover nuts that hold the saw bar to the saw body.
   Note : Do not remove the nuts.

6. Tip bar up and adjust the tension screw.

7. Re-perform the chain tension check and repeat if necessary.

Tool Operation – Detail C

Connect to Water

1. Connect a standard garden hose to the water connection.
   Note : Water pressure must be at least 20 PSI.
   Connect to a Hydraulic Power Supply

2. Using a calibrated flow and pressure gauge, check the output of the hydraulic power source. Ensure it matches the flow and pressure in “Specifications” on page 6. Hydraulic fluid must be 50°F or above. Preheat if necessary.
   Note : Proper hydraulic flow and pressure are necessary to ensure proper speed of the chain.

3. Ensure that the hydraulic power source is equipped with a relief valve set to open at the maximum relief pressure (see ”Specifications” on page 6).

4. Wipe hose couplers with a clean, lint free cloth.

5. Connect the return hose to the male coupler.

6. Connect the pressure hose to the female coupler.

7. Ensure couplers are undamaged, properly connected and are tight.

8. Ensure the tool trigger is not engaged.

9. Power up the hydraulic power supply.
   Plan the Cut

10. If cutting pipe 8 – 12 inches in diameter, STANLEY recommends using the pipe clamp accessory. See “Installing and Using the Saw Clamp Accessory” on page 10.

11. Ensure the chain guard and hand guard are installed and are not damaged. Disconnect the tool from the hydraulic power supply and replace immediately if missing or damaged.

12. Ensure the material being cut is clamped or otherwise secured so that it cannot move during the cut. Position the saw to avoid pinching the bar or chain as the material is cut.

13. Ensure that the cut can be made without the chain making contact with he ground.

14. Mark the planned cut on the material.

15. Plan the cut so that you will not be injured by falling cut-off material.

16. Do not cut with excessive force. The chain could slow and stall, which could cause premature wear of the saw bar and chain.
    Tool Use

17. Wrap your right hand around the trigger handle.

18. Wrap your left hand around the assist handle.
      Keep all body parts away from the chain during operation. Moving chains are sharp and can cause death or serious injury.

19. Stand in the back of the tool.

20. Hold the tool with a light, but safe, grip taking account of the required hand-reaction forces, because the risk from vibration is generally greater when the grip force is higher.
    Note : Hold the tool correctly and be ready to counteract normal or sudden movements. Have both hands available. Holding the tool correctly will help reduce kickback.

21. Lift the tool, holding the saw bar away from you.

22. Ensure the saw chain is not touching the material to be cut.

23. Hold down the trigger lock.

24. Slowly hold down the trigger.

25. Run the tool for at least two minutes. Ensure the tool is running properly. If considerable vibration or other defects are detected, stop operation immediately. Contact your STANLEY dealer for service.

    Note : Release the trigger in case of interruption of the hydraulic power supply.

27. Feed the saw into the material to be cut. Keep feed force over the center line of the saw.

28. During the cut, do not stand in the way of the water discharge as it can contain small pieces of material moving at high velocity.
    Note : Do not feed the saw with force greater than 45 Lbs. (20 Kg).

29. When the cut is finished, release the trigger to stop the saw.

Installing and Using the Saw Clamp Accessory

Before cutting, ensure the pipe is in a safe condition to be cut. Support the work piece so that the cut remains open during the cutting operation and when finished. Pinching the chain can cause death, serious injury or chain damage.

The pipe clamp must be attached to the work piece so it does not move during the cutting operation and/or when the cut is finished. Unexpected movement of the clamp could cause loss of control of the saw and could result in death or serious injury to the operator.

Do not install, change tool accessories or perform maintenance on the tool while the hydraulic power source is connected. Accidental engagement of the tool can cause serious injury. Disconnect the hydraulic power source and put the direction control in neutral before servicing.

1. Disconnect the tool from the hydraulic power supply.
2. Remove the two nuts and washers that secure the chain guard to the saw and install the axle over the chain guard, then re-install the two nuts and washers. Install DS12 to the axle of the saw clamp over the chain guard.
3. Re-install the chain guard hardware.

Use

1. Place the clamp around the top of the pipe and hand tighten the adjustment nut.
2. Position the saw with the attached axle on the pipe clamp by sliding the saw clamp axle through the receiver hole at top of the clamp. Secure with a snap pin.
3. Ensure that the saw is positioned to allow the handle to pivot during the cut unobstructed and to ensure that the saw tip doesn’t contact dirt. If necessary, reposition the saw clamp/saw assembly around the pipe to optimum cutting position.
4. Tighten the clamp nut with a wrench to ensure that clamp does not move during cutting operation.
5. When cutting is finished, remove the hydraulic power supply from the tool, then remove the tool from the clamp.

Cutting Tips

• Position the saw to avoid pinching the blade or the chain as the pipe is cut. Support both ends of the pipe to prevent movement and possible injury to the operator.
• Hold the saw so that the chain isn’t in contact with the pipe. Start the water and activate the saw to full power. Press the chain against the pipe slowly, applying pressure to cut through the pipe.
• Pressure can be applied to the cut until the saw motor starts to lug.

Maintenance

Chain saw chains and bars are very sharp. Do not touch without proper Personal Protective Equipment (PPE). Wear leather gloves and only grab the diamond segments of the chain when adjusting chain tension. Serious cuts and abrasions can occur.

Do not install, change tool accessories or perform maintenance on the tool while the hydraulic power source is connected. Accidental engagement of the tool can cause serious injury. Disconnect the hydraulic power source and put the direction control in neutral before servicing.

Daily Maintenance

1. Check chain tension and adjust if necessary. See “Check & Adjust Chain Tension – Detail B” on page 9.
2. Check all hydraulic connections for damage. Replace if damaged.
3. Ensure the chain guard and hand guard are in place and are not damaged. Replace if missing or damaged.
4. Oil the chain to prevent rust.

Check for Saw Bar Wear – Detail D

The saw bar can develop a bur on the edge of the saw bar channel. If a bur develops, redress the saw bar.

1. Disconnect the tool from the hydraulic power supply.
2. Remove the saw bar and chain, as shown in Detail “E” on page 4.
3. Using a square, ensure the saw bar channel is square.
4. If a bur exists, use a flat file to file off the bur until the saw bar channel is square.
5. Check the saw bar bows or bends. If found, replace the saw bar.
6. Periodically remove the saw bar and rotate it. This will allow the saw bar to wear evenly

Replacing the Chain and Bar – Detail E

1. Disconnect the tool from the hydraulic power supply.
2. Loosen the chain tension screw.
3. Remove the saw bar and chain.
4. Replace the chain or bar. See “Accessories” on page 11.
