Note: Shut off air supply and release all air pressure before filling. Disconnect airline before changing restrictors or servicing.

The lubricator is filled through a grease nipple, with a manual or air driven barrel pump.

Installing To The Air Line
Your "Hal" lubricator replaces your existing oil lubricator. There are no changes to the set up. Install the air-in (from the header) to the square end of the lubricator. At the lubricator end, prime the stinger hose (the hose going to the drill), by injecting a 1/4" tube of grease directly into the airline (only required on a first-time installation).

While Drilling
Your Hal lubricator has a #70 restrictor installed (P/N H-70). Also supplied, are the optional restrictors: #91, #81, #73, #67, and #65. Additional sizes are available upon request (they come in a wide range of, incremental larger, or smaller, sizes). The smaller the number, the less grease delivered. Factors deciding the proper restrictor size are: drill type, stoper or jackleg; drill make, Joy, Sig, Secan, GD, IR, etc. ; temperature; amount of water in air line and the type of drilling. If you are drilling in "room temperature," conditions with a Secan, GD, IR, or Joy jackleg, a #65 restrictor will probably deliver the right amount of lubrication. A Secan, GD, IR or Joy stoper, in the same temperature, will require a larger restrictor (a #67 or # 70). If drilling in a raise, with a stoper, a #70, or larger, is required (this is to offset the effects of gravity, when the lubricator is hanging in a vertical position). Grease consumption will vary, depending on the conditions. For example, drilling uppers, with a stoper, in a near freezing stope, will require a #89, or larger, restrictor. Extreme cold conditions will require a lighter, winter grade, grease. Warm conditions (85 deg+) will require a smaller restrictor (#50 or smaller). Initially, set your lubricator to use approximately 70 grams per one hour of drilling. This setting equates to 300 – 500 feet, drift drilling, per one tube (300 grams) of grease. Consumption is higher, when installing rockbolts. Monitor, for a shift or two. I f necessary, change grease delivery (by changing the restrictor size) to meet your specific requirements.

NOTE: Initially, refill the lubricator midway through the shift, to determine actual grease consumption. This is to prevent burning the drills up because of lack of grease. Over greasing can also cause problems. The drill, and work area, becomes messy with grease and, if not checked, the lubricator will run dry, part way through the shift, causing premature failure to the drill.

While drilling, you might not see the grease coming out of the exhaust. To verify that you are getting proper lubrication, hold a clean piece of cardboard in front of the drill exhaust while drilling. A noticeable "film" should appear on the cardboard. Also, you require a film of grease in the chuck insert. If one, or both, conditions do not exist, install a larger restrictor.

• Problem - The drill is getting covered in grease, creating a messy situation.
  
  Cause - The restrictor setting is too big. Install a smaller one and monitor grease consumption.
   
• Problem - Lubricator fails to deliver adequate lubrication.
  
  Possible Cause (1) - Restrictor (P/N H-xx) is plugged. To check, remove the airlines from the drill the lubricator. Re-fill the lubricator with grease. When full, keep trying to insert grease into the lubricator, while looking into the end of the lubricator, at the restrictor. If clear, you will see grease "oozing" through the restrictor. If nothing comes out, remove the restrictor and clean. Exhaust some grease out of the grease reservoir (by pushing on the reservoir piston) and reinstall the restrictor.
  
  Possible Cause (2) - Internal cylinder is filled with foreign material preventing piston (P/N H-02) to travel freely. Lubricator requires servicing. Note: Airlines that have excessive rust scale require an air filter to prevent premature failure and operation of the drill and lubricator.
  
  Possible Cause (3) - Restrictor size is too small. Install a larger restrictor.
  
  Possible Cause (4) - Airline connections are loose and/or there is a pin- hole in the air- line, allowing the grease to escape. Therefore, the drill will not receive proper lubrication.
  
  Possible cause (5) - Lubricator is running empty, part way through the shift. It is possible the resrictor is too large.
    
• Problem - Drill is stalling and/or freezing up.
  
  Possible Cause (1) - Abnormal amount of water in airlines. Install a larger restrictor. Note: An airline water separator is required.
   
• Problem - The leg, on the drill, is sticking .
  
  Possible cause - Insufficient grease delivery. Install a larger size.

Servicing

Remove the restrictor (P/N H-xx). By pushing on the reservoir piston (P/N H-03), exhaust all the grease. With a bottle washing brush, thoroughly clean out the lubricator in a wash tank. For proper operation, the piston (P/N H-03) must slide freely back and fourth, in the reservoir, when the lubricator is rocked in your hands.
