Dust and Fumes

• WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm. Some examples of these chemicals are:

• Lead from lead-based paints,

• crystalline silica from bricks and cement and other masonry products, and

• arsenic and chromium from chemically treated lumber.
  Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well-ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles. Protect yourself and those around you. Research and understand the materials you are drilling. Follow correct safety procedures and comply with all applicable national, state, or provisional health and safety regulations relating to them, including if appropriate arranging for the safe disposal of the materials by a qualified person.

• When dust or fumes are created, control them at the point of emission. Direct tool exhaust to minimize disturbance of dust.

• Operate and maintain the tool as recommended in this manual to minimize dust.

• Use respiratory protection in accordance with employers’ instructions or as required by occupational health and safety regulations.

• Avoid prolonged contact with dust. Allowing dust to get into your mouth, eyes or lay on the skin may promote the absorption of harmful chemicals.

• Select and replace tool bits as recommended in order to prevent an unnecessary increase in dust or fumes.

• Keep tool handles dry, clean, and free from oil and grease. This will enable better control of the tool.

PPE

• Always wear safety equipment such as impact-resistant goggles, ear protection, head protection, breathing protection, and safety shoes at all times when operating the tool.

Parts of a DL07 – Detail A

Tool Setup

Do not install or change tool accessories while the hydraulic power source is connected. Accidental engagement of the tool can cause serious injury. Disconnect the hydraulic power source before installing or changing accessories.

1. Disconnect the tool from the hydraulic power source.
   Install Assist Handle & Set Hydraulic Circuit Type – Detail B
   The assist handle helps to absorb reaction torque and control the tool. Loss of control can cause personal injury. STANLEY recommends you use the assist
   handle whenever possible.

2. Screw the assist handle into the drill body.
   Note: The assist handle is held with your non-dominant hand.

3. Remove the hex plug on the back of the tool handle.

4. Turn the selector screw completely clockwise for open center operation
   -OR- completely counterclockwise for closed center operation.

5. Reinstall the hex plug.

Insert Bit & Choose Drill Rotation Direction – Detail C

1. Open the drill chuck using the chuck key.

2. Insert the bit, center it and tighten the chuck.
   Note: Never operate the tool unless the inserted bit is retained. Bit can become a high-velocity projectile. Secure the bit by tightening the chuck.

3. Store the chuck key away from the drill.
   Do not operate the tool with the chuck key inserted into the chuck. A chuck key left attached to a rotating part of the tool may result in personal injury.

4. Push the rotation direction spool left for clockwise bit rotation -OR- right for counterclockwise bit rotation.

Tool Operation

Set Depth Gauge – Detail D
Note: The depth gauge is included with Models DL07552B, DL07552M,
DL07552S, DL07572B & DL07572S.
Do not set or reset the depth gauge if the hydraulic power source is connected. Accidental engagement of the tool can cause serious injury. Disconnect the hydraulic power source before setting or resetting accessories.

1. Loosen the depth gauge thumb screw.
2. Slide the depth gauge rod so that the distance between the rod tip and the bit tip is equal to your drilling depth.
3. Tighten the thumb screw.
4. When drilling, the depth gauge will contact the material being drilled, stopping the bit from progressing further.

Connect to a Hydraulic Power Source – Detail E

1. 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 9. The hydraulic fluid must be 50°F or above. Preheat if necessary.
   Note: Check the hydraulic power source once a day. Proper flow and pressure is critical to maintaining proper tool speed.

2. Ensure that the hydraulic power source is equipped with a relief valve set to open at the maximum relief pressure, see “Specifications” on page 9.

3.  Wipe hose couplers with a clean, lint-free cloth.

4. Connect the return hose to the tool port marked “Out”.

5. Connect the pressure hose to the tool port marked “In”.

6. Ensure all hydraulic connections are tight.
   Using the Tool – Detail E

7. Hold the main tool handle with your dominant hand.

8. Hold the assist handle with your non-dominant hand.

9. Press the drill bit against the material to be drilled, at a 90° angle.

10. Squeeze the tool trigger.
    Note: Hold the tool correctly and be ready to counteract normal or sudden movements. Have both hands available. High reaction torque can develop if the tool stalls, which can be caused by excessive loads being applied to the drill bit, by the drill snagging on the material being drilled into or by the drill bit breaking through the material being drilled.

11.  Release Trigger to stop the tool.
    Note: If you encounter a breakdown or the tool stops for any reason, release the trigger and power down the hydraulic power source.

Drilling Tips

• Ductile material, such as metal or wood, is best drilled when a steady downforce is applied.
• When drilling metal, use a cutting lubricant to prolong bit life and to reduce the force required to drill.
• When drilling large holes, create smaller holes first, then incrementally work your way up to larger bits. Each bit must be selected so that it’s too large to thread and jam into an existing hole. Otherwise, the bit may break and become a hazard.
• Never use a dull bit as they can cause more vibration. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

Tool Maintenance

Use only accessories, consumables and parts recommended by STANLEY.
Daily Maintenance

1. Remove hydraulic power from the tool.
2. Check all hydraulic connections and hoses for damage. Replace damaged parts before operating the tool.
3. Inspect the drill chuck and associated parts. Replace when they have become worn, cracked or distorted.
4. Inspect tool to ensure all decals are legible. Contact STANLEY if replacements are needed.

Underwater Tool Maintenance

1. Remove hydraulic power from the tool.
2. Using water displacing oil, spray into the trigger3. Spray into the chuck.
3. Spray or dip the entire tool.

Tool Storage & Transport
Drain the tool of hydraulic fluid and plug open hydraulic ports. Clean the tool and store in a clean, dry space that is safe from damage. Ensure the tool is secured and will not move during transport. An unsecured tool could cause injury or damage to the tool.

Tool Disposal

Hydraulic Oil
Hydraulic oil can contaminate the air, ground and water if not properly recycled. Recycle hydraulic oil in accordance with all State, Federal and local laws, at your local oil recycling facility.
Hydraulic Hoses
Hang hydraulic hoses to drain. Collect the oil for recycling. Contact your local municipal recycling authorities for an approved hydraulic hose recycling site.
