The following guidelines are provided to insure safe operation of Standard Pneumatic's 2600 Series Pneumatic Screwdrivers.

• Always operate, inspect, and maintain any tool in accordance with American National Standards Institute Safety Code for Portable Air Tools (ANSI B1869.1)
  

• For safety, top performance, and maximum durability of parts, operate these tools at 90 psig (6.2bar/620kPa) maximum air pressure at the inlet with 1/4" (6mm) ID air hose.
  

• Always turn off and disconnect the air supply before installing, removing, or adjusting any accessory on this tool, or before performing any maintenance or repair.
  

• Keep hands, loose clothing, and long hair away from the rotating end of the tool.
  

• Anticipate and be alert for sudden changes in motion during start up and operation of any power tool.
  

• Standard Pneumatic is not responsible for damage caused by any customer modifications of tools.
  

• Always use clean, dry air. Dust, Corrosive fumes, or excessive moisture can damage the motor of an air tool. An air line filter and lubricator are required.
  

• Do not disassemble if the tool is still in the warranty period. Disassembly by anyone who is not an authorized Standard Pneumatic service technician will void the warranty.
  

• Low or fluctuating air pressure causes variations in tool speed and can result in inaccurate torque values.

• 11/16" open end wrench
  

• Strap wrench
  

• Retaining ring pliers
  

• Small Hammer
  

• Punch (p3 or similar)
  

• 1" Micrometer
  

• Small arbor press
  

• Pencil with eraser, or plastic rod (6" long)
  

• Flat plate (glass or other)
  

• Emery cloth
  

• Tachometer
  

• Container (at least 6" wide with low walls)

The ideal air supply to our tools can be achieved with our model 280 Filter-Regulator-Lubricator. The filter element removes contaminating solids, oils and liquids which may be in the compressed air line whether newly installed or not. This filter unit is equipped with a petcock for ÒdumpingÓ the contaminants without shutting off the air supply.

The regulator controls the air supply to maintain a constant pressure at the tool even though there are changes in the flow demand and or inlet pressure.

When other manufactures of lubricators are used, it is recommended that the customer check with that particular manufacturer for the proper procedure for setting the lubricator to deliver 1/10 of a drop per minute to the tool. Many lubricators, especially larger units, require high airflow rates for the lubricator to operate properly. Therefore, the manufacture should also be asked to verify the operation of the lubricator at a 3.6 cfm flow rate for the 2000 series.

Multiple tools on one air system present another problem. When several tools are connected to the same lubricator, it is not possible for the correct amount of lubrication to go to each tool. Since it is highly unlikely that the same number of tools would also be in operation at the same time, the airflow through the lubricator would be a variable; thus the amount of lubrication put into the airflow would also vary, however, with the micro fog type of lubricator, such as our model 280, the oil particle size is such that the oil stays suspended in the air through several takeoffs better than with other types of lubricators without wetting out, which results in multiple tools on the same line being better lubricated.

The position of the various tools in the system in relation to the distance away from the lubricator would also cause a variance in the amount of lubrication to each tool. If several tools must be connected to the same lubricator, the same procedure for setting the amount of the lubrication on the unit should be used with only one of the tools running. It is assumed that the increased airflow of tools operating at the same time will pull more oil into the system. The maximum number of tools that we recommend to one Model 280 is two.

1. Use Standard Pneumatic Tool lubricant (Part Number 100) or a S.A.E. 10 wt
non-detergent oil for lubricating the motor.

2. Generously lubricate rotor and rotor blades prior to reassembly of the motor.

3.The spindle (item 23) should be lightly greased on the gear teeth.

4.Coat all idler gears with Dana AX Multifuse grease or equivalent.

NOTE: Whenever a 2600 series tool is to be placed in a vise, use leather or copper covered vise jaws to protect the surface of the part or tool and help prevent distortion. This is especially true of motor housings and threaded portions of the housing. Distortion of the motor housing could result in irreparable damage. (Numbers in parentheses refer to numbered parts in parts drawing)

1. Grasp the tool and remove the clutch housing (34) by turning the housing clockwise (left hand thread). If the clutch housing will not unscrew by hand, then grasp the tool in a padded jaw vise and use a strap wrench to loosen the housing.

2. Remove the clutch from the motor housing assembly, taking special care not to bend the push rod (4).

3. Place an 11/16" open end wrench on the flats of the head assembly, turn clockwise to loosen, and continue turning until the head assembly separates from the motor housing (36). Carefully remove the head and push rod from the motor housing.

4. Remove the motor and drive train assemblies from the motor housing by using a pencil to push them through the housing. Insert the pencil, eraser first into the external threaded end of the housing. Note: place a shallow container under the motor and gear assembly prior to disassembling. The alignment pin will fall loose when the spindle gear and bearing are removed from the rotor.

5. Remove the motor assembly (items 15 through 25) from the gear assembly. Disassemble the motor by removing the cover plate (15), bearing ring (16), bearing (17), upper end plate (18), and alignment pin (19) from the cylinder (20). Slide the cylinder from the rotor/spindle gear and remove the rotor blades (22) from the slots in the rotor (21). Remove the spindle gear (25), bearing (17), bearing lower ring (24), and lower end plate (23) from the rotor. The alignment pin (14) will drop when the spindle gear and the rotor are separated.

6. Check bearings (17) for excessive side play and smooth rotations. Check that the press fit of the bearing and spindle (25) is still solid. Inspect the rotor, lower end plate (23), and upper end plate (18) for any scoring or excessive wear. The teeth of the spindle gear (25) should be checked for burrs or excessive wear.

7. If the upper or lower end plates are slightly scored they can be refurbished by placing a sheet of emery cloth on a flat surface, such as a piece of glass or plate and then lightly sliding them cross ways until a good finish has been achieved. Note: Always make sure that each item is flat against the emery cloth and this process should only be performed if the end plates are only slightly scored.

8. Remove the ring gears (26, 27) and idler gears (32) from the idler gear plate (28), and driver/pin assembly (29). Inspect all ring gears and idler gears for burrs, chips, and excessive wear. Check bearings (33,34) for wear and smooth rotation. After cleaning idler gears, place them on the pins of the idler gear plate and driver/pin assembly. Rotate each gear making sure it turns smoothly.

9. If the bearing (33) requires replacement, remove the retaining ring (35) from the driver/pin assembly (29). Press the driver/pin assembly (29) from the bearing (34). For the idler gear assembly, press the short spindle gear (30) from the bearing (33), making sure not to loose the alignment pin,

10. Disassemble the head assembly using a snap ring pliers to remove the retaining ring (5), then remove the muffler cap (6) and muffler (7). The muffler should be replaced whenever the tool is in for repair or maintenance. Visually inspect the push rod for straightness. If the push rod must be replaced, then remove the retaining ring (2) using a metal rod about the same diameter as the push rod, bent into a hook.

11. If it is found that the reverse does not function or the reverse valve (12) does not move freely, the tool should be sent back to Standard Pneumatic and Electric Tool Company for evaluation and repair.

12. Clean all parts thoroughly, using cleaning solvent, acetone, or an ultrasonic cleaner/specified soap.
